The Unyielding Protector: Mastering Extreme Environments with Fiber Glass Felt

In industries where temperatures soar, chemicals abound, and safety is paramount, conventional materials often fall short. From industrial furnaces operating at scorching heats to exhaust systems managing hot gases, the need for a material that can withstand such brutal conditions without degradation is critical. This is where Fiber Glass Felt emerges as an indispensable solution – a high-performance nonwoven material engineered for the extreme.

Fiber Glass Felt is not just an insulator; it's a testament to material science, offering unparalleled thermal stability, chemical resistance, and non-combustibility. It provides a robust shield against heat, noise, and corrosive elements, ensuring the longevity and safety of vital systems.

At PARKNONWOVEN, with our state-of-the-art manufacturing facilities in Gurugram, Haryana, India, we are a leading producer of high-performance nonwoven felts, including specialized Fiber Glass Felt, precisely engineered to excel in the most challenging industrial and automotive applications.

The Unyielding Protector: What is Fiber Glass Felt?

Fiber Glass Felt is a type of nonwoven felt fabric made predominantly, or entirely, from glass fibers. Unlike synthetic polymer-based felts (like polyester or polypropylene), fiberglass is an inorganic material derived from glass, giving it inherently superior properties for high-temperature and harsh environments.

In the nonwoven manufacturing process, discrete glass fibers are mechanically or chemically bonded into a flexible, porous felt structure. This unique construction provides a highly effective medium for:

Thermal Insulation: Trapping air within its structure to impede heat transfer.

Acoustic Absorption: Dampening sound waves due to its open, fibrous network.

Filtration: Capturing particulates from hot gases or corrosive liquids.

Reinforcement: Providing structural integrity in various composite applications.

Built for Extremes: Why Fiberglass is the Material of Choice for Felt

The exceptional performance of Fiber Glass Felt stems directly from the inherent properties of glass fibers:

Extreme High Temperature Resistance: Glass fibers possess a very high softening point, allowing the felt to withstand continuous operating temperatures that would melt or degrade most organic and synthetic polymer fibers. It remains stable and functional even in intense heat.

Inherent Non-Combustibility: Fiberglass is fundamentally inorganic and will not burn, char, melt, drip, or produce significant smoke or toxic fumes when exposed to fire. This makes it an invaluable material for fire safety applications.

Exceptional Chemical Inertness: Glass is highly resistant to a broad spectrum of acids, alkalis, solvents, and corrosive gases. This makes fiberglass felt ideal for environments where chemical attack is a concern.

Superior Dimensional Stability: Fiberglass has a very low coefficient of thermal expansion, meaning the felt maintains its shape, size, and integrity even under extreme temperature fluctuations and mechanical stress, preventing shrinkage or deformation.

High Tensile Strength: Despite its fibrous nature, glass fibers are remarkably strong, providing the felt with good tensile and tear strength.

Good Acoustic Absorption: The porous, entangled structure of the felt effectively dissipates sound energy, contributing to noise reduction.

Electrical Insulation: Glass fibers are non-conductive, offering excellent electrical insulation properties.

Mastering the Inferno: Key Properties of High-Performance Fiber Glass Felt

The strategic manufacturing of Fiber Glass Felt unlocks a powerful combination of features:

Unmatched Thermal Resistance: Capable of continuous operation up to 500-800°C (depending on specific glass type and binder system), with intermittent exposure to even higher temperatures.

Excellent Thermal Conductivity (Low): Efficiently limits heat transfer, providing superior insulation in hot industrial processes, pipes, and equipment.

High Sound Absorption Coefficient: Effectively dampens noise across a wide frequency range.

Corrosion Resistance: Maintains structural and chemical integrity in aggressive chemical environments.

Non-Flammable & Self-Extinguishing: Provides inherent fire barrier properties.

Resistant to Moisture & Fungi: Glass fibers do not absorb moisture or support microbial growth.

Durability & Long Lifespan: Withstands harsh operating conditions, reducing the need for frequent replacement.

Customizable Density & Porosity: Can be engineered for specific insulation thickness, firmness, or filtration efficiency.

From Raw Glass to Resilient Felt: The Manufacturing Process (Simplified)

The production of Fiber Glass Felt requires specialized equipment and expertise:

Fiber Preparation: Continuous glass filaments are precisely chopped into staple fibers of specific lengths, optimizing them for nonwoven processing.

Web Formation: These chopped fibers are then carefully opened and formed into a uniform, loose fibrous web, typically using advanced dry-laid (air-laying or carding) or sometimes wet-laid technologies.

Consolidation: The fragile glass fiber web is then consolidated into a coherent felt. The most common method is needlepunching, where thousands of barbed needles mechanically entangle the glass fibers, creating a strong, durable felt structure without the need for significant chemical binders. In some cases, a high-temperature resistant binder may be incorporated for enhanced integrity in specific applications.

Finishing: The felt may undergo specialized heat treatments or surface modifications to optimize its performance characteristics for its intended end-use.

Applications Where Performance is Non-Negotiable: Uses of Fiber Glass Felt

The unique properties of Fiber Glass Felt make it indispensable in a variety of critical high-temperature and demanding applications:

High-Temperature Industrial Insulation:

Lining and insulation in industrial furnaces, ovens, kilns, and boilers.

Thermal wraps for hot pipes, ducts, and machinery in power plants, refineries, and chemical processing facilities.

Insulation for turbines and exhaust stacks.

Hot Gas Filtration:

Filter media for removing particulates from high-temperature exhaust gases and industrial emissions, common in incinerators and cement plants.

Acoustic Insulation & Sound Dampening:

Liners and blankets in engine compartments (automotive, marine, industrial generators) for heat and noise control.

Acoustic panels in industrial environments.

Composite Reinforcement:

As a reinforcement mat in specialized composite materials (e.g., fiberglass reinforced plastics - FRP) where high temperature resistance, dimensional stability, or chemical inertness are required.

Fire Barriers & Protective Layers:

Components in fire doors, fire blankets, and protective barriers in buildings and transportation.

High-Temperature Gasketing & Sealing:

Used as resilient, high-temperature resistant gaskets and seals in industrial equipment.

The Unrivaled Benefits: Investing in Quality Fiber Glass Felt

Choosing high-quality Fiber Glass Felt provides a multitude of advantages:

Unmatched Thermal Performance: Ensures thermal efficiency and protection in extreme heat.

Enhanced Safety: Provides inherent fire protection, preventing ignition and spread of flames.

Exceptional Durability: Withstands continuous exposure to harsh conditions, reducing replacement frequency.

Superior Chemical Resistance: Maintains integrity in corrosive or chemically aggressive environments.

Effective Sound Control: Contributes significantly to noise reduction in loud machinery and processes.

Customer reviews: iRobot Roomba 761 review

If cleaning the floor makes you feel tired, the iRobot Roomba 761 review – smart vacuum cleaner will help you effectively. There are many Roomba models to choose from, which makes it difficult for buyers to determine which one is best suited to their home cleaning requirements. The iRobot Roomba 761 smart vacuum cleaner is the new iRobot house cleaning robot and is said to have powerful features that help clean the floor. On the surface, the iRobot Roomba 761 smart vacuum cleaner is quite similar to the model 770 in size and main features, and really, it is only inferior to the version after each trash signaling function is full. The rest of the iRobot Roomba 700 series models come equipped with the same brush and motor as well as cleaning capabilities. The price of these smart vacuum cleaners is not cheap, If you can not afford the most advanced or not too interested in the above functions, you can completely pay attention to this smart vacuum cleaner iRobot Roomba 761. There is only a slight difference between the two models but you can save money.

iRobot Roomba 761 Review in 2020

Salient features of iRobot Roomba 761

The cleaning capabilities of the iRobot Roomba 761 smart vacuum cleaner

The iRobot Roomba 761 smart vacuum cleaner is specially designed for optimal cleaning and easily adapts to any type of floor. It is equipped with a HEPA dual filter that can remove all trash and allergens it comes in contact with. In fact, this filter is capable of removing even the smallest dust particles, allowing up to 98% dust extraction performance, allergens and dust particles.

Vacuuming on floor types: Like previous models, the Roomba 761 works best on bare surfaces, removing pet hair, dust, and trash from around the room with impressive efficiency. However, it can only remove loose particles, not vacuum if it gets stuck on the floor.

Carpet cleaning: iRobot Roomba 761 smart vacuum cleaner can clean quite well on most carpet surfaces. However, do not expect them to work well on thick carpets because they do not have the ability to clean deep inside the carpet fibers like conventional large vacuum cleaners.

Usually the iRobot Roomba 761 smart vacuum cleaner does not have any trouble moving from floor to carpet, as long as the carpet is not too thick. Vacuuming on medium thickness or thin carpet will not make this machine difficult as long as you hide all the fringes decorated the edge of the carpet so they do not get stuck or get caught in the robot.

Removing pet hair: As mentioned above, one of the great differences of the Roomba 761 is that the two motor-mounted brushes come with an extra brush that can help effectively with the removal of pet hair. . This explains why the Roomba 761 is especially popular with pet owners. However, you should note that you must regularly maintain the machine by removing the bristles around the brush. If your pet has short hairs, then you don’t need to do this as often.

Control and use the iRobot Roomba 761 intelligent vacuum cleaner

One of the highlights of the iRobot Roomba 761 smart vacuum cleaner is its extremely simple usage. With just a small press of the button “Clean”, the device is ready to work.

The iRobot Roomba 761 smart vacuum cleaner is reinforced with a polymer collision damping bar, which helps this robot mop and vacuum the house to gently move around furniture and furnishings without causing any damage. Damage or scratches that still complete the cleaning job at maximum efficiency. Alternatively, you can optionally install the Roomba 761 so that it automatically cleans the house on different days of the week and even set how long it works. This means that even if you are not at home, you still get clean floors.

Smart cleaning ability

The iRobot Roomba 761 smart vacuum cleaner is equipped with the patented iAdapt response cleaning technology. Basically, this technology allows devices to automatically search for certain areas that are often overlooked in the home if using a traditional vacuum cleaner. These include nooks and crannies under furniture, under cabinets and other hard-to-reach areas where conventional standing vacuum cleaners are not able to clean.

The iRobot Roomba 761 smart vacuum cleaner is also designed to focus on places with more dirt to ensure a thorough cleaning and application of a translational movement. Discrete dust particles are sucked up and put into the AeroVac trash compartment, along with the Roomba 761’s air dispersion system to optimize the efficiency of vacuuming, especially hair and dirt.

Flexible navigation

Like the other iRobot Roomba 761 smart vacuum cleaners in the 700 series, the Roomba 761 is built with iAdapt technology. In addition to finding dirt, it is capable of making 60 decisions per second in terms of cleaning orientation. Over time, it will work more effectively because it already belongs to the layout of the house as well as the shape of the rooms in your home.

With each house, the iRobot Roomba 761 smart vacuum cleaner has a different adaptation time. The sensor system can detect the sound from the smallest dust particles and control the machine to move to the area with the most dust, clean first.

Like other vacuum cleaner robots on the market today, you need to create a space as open as possible for the robot to maximize performance. So remember to keep loose wires, scattered papers, toys and litter boxes in the house, as these are obstacles that affect its efficiency and cleaning ability.

Operation time

The average operating time of the iRobot Roomba 761 smart vacuum cleaner is 90 minutes. After this time, you need to charge it for about 3 hours on average. This product comes with a rechargeable battery and a self-charging device (home base). The iRobot Roomba 761 Smart Vacuum Cleaner also includes intelligent Virtual Wall (virtual wall) technology, which helps the Roomba 761 clean up where you install it and prevent it from exceeding the limits of that area. Virtual Wall requires 2 C batteries (not included in the product). The remote also requires 2 AA batteries (this kit is not included).

Customer service and warranty when buying iRobot Roomba 761 smart vacuum cleaner

IRobot Roomba 761 smart vacuum cleaner comes with a one-year warranty and 6-month warranty for the battery. The manufacturer of iRobot will replace any defective product as long as it is identified as a faulty manufacturer and not a fault due to misuse or negligence of the user.

Seafarers Must Adapt to the Rapid Evolution of Piracy

In two recent articles, Sea Piracy in 2025: Piracy 2.0? and Countering Gulf of Guinea Piracy Towards 2025 I tried to map out the possible evolution of piracy within Gulf of Guinea until 2025. Then I analyzed the different possible actions to reduce this threat. This analysis cannot be complete without integrating the main actor, the seafarer. This third article therefore concerns the how seafarers must adapt to the rapid evolution of pirate activities.

It’s noticeable that this domain for seafarers is based on regulatory documentation that is low in volume and weak in practical guidance. The Ship Security Plan (SSP) is the basis for maritime security regulations. This document, established after the USS Cole, Limburg and September 11 attacks, was mainly focused on maritime terrorism. The content has been lightly modified since, integrating some requirements arising from the evolution of piracy.

The ISPS regulation does not go deeper on practical measures concerning vessel, crew members, equipment and procedures when looking at piracy. To cover the seafarers practical needs a group of associations published a document called Best Management Practices in early 2000. This document, dedicated to deter piracy and enhance maritime security in the Red sea, Gulf of Aden, Indian Ocean and Arabian sea has been reviewed several times since (Last review BMP 5 –June 2018). To respond to the specific Gulf of Guinea environment, one document, Guideline for Owners, Operators and Masters for Protection against Piracy in the Gulf of Guinea Region has been established by the same structure.

Finally, as the piracy epicenter as moved from East Africa to West Africa, one new document BMP West Africa has been issued beginning 2020 to provide threat mitigation guidance on counter-piracy/armed robbery at sea and to help companies and mariners to risk assess voyages while operating along the West African coast.

Despite the evolution of communications at sea, the captain is an isolated leader. His or her job requires quick decisions concerning a wide variety of situations. If the situation allows, he can try to establish a telephone connection but, the handset hung up, he becomes again, isolated. A piracy attack is a dynamic event testing a captain's competency and reactivity. This situation can be illustrated by the Captain Phillips movie scene where Tom Hanks calls the MSCHOA. As with everything else, a captain must be informed, trained, prepared.

This readiness must not only apply to seafarers, it should be also concern the vessel. “If you ignore both your enemy and yourself, you will only count your fights by your defeats.” This citation should be a guide for a captain or ship security officer (SSO) operating within the Gulf of Guinea. The pirates' boarding rate within Gulf of Guinea is very high. As said in my previous article, there are several reasons for this. Some are linked to the combination of operational capacities of pirates and the lack of military responses (PMSC / escort vessel) but it is obvious that somet of the reasons are linked to another conjunction: ignorance of West Africa pirates, to their profiles and their modes of action.

As such, it would be interesting to test the captains/SSOs to make them draw Gulf of Guinea pirates. To help their sketches, we can try to characterize them by some elements:

Use of fiber speed boat, eight to 10 meters long, usually sporting colored flags (mainly red or white), usually motorized by two outboard engines, 150/200 Hp, more than six men onboard (usually eight to 10), men armed with AK 47, speed boat fitted with an aluminum ladder eight to 10 meters long. Pirates can operate on one sole speed boat, sometimes in pairs.

It’s noteworthy that numerous specialized articles speaking about Gulf of Guinea piracy are illustrated by a very well-known picture showing a speed boat having a mounted Cal 50 machine gun and transporting……MEND militants. If the picture is beautiful, it’s not related to real Gulf of Guinea pirates. Sometimes this picture is replaced by the view of one skiff transporting Somalian sea pirates. This pictorial materialization may disturb the initial perception of what a Gulf of Guinea pirate is.

The fiber vessels don't offer a strong Radar Cross Section, navigational radars have limited capacities. The pirates' speed boat emerges on the radar screen at about three nautical miles when the sea state is under three and the speed is high. It’s highly recommended that one radar be set on short pulse/ short range, the AC SEA/AC RAIN setting in accordance. It’s possible that watchkeepers will detect the approach by the noise before sight or radar screen. The approach axes can be various but the CPA (Closest Point of Approach) is …0.

The time of the attack varies too and is evolving regularly. In 2018, almost two thirds of the piracy attacks was conducted by daylight. Currently, piracy attacks within Gulf of Guinea are mainly conducted at night time and mainly at the beginning or end of the night.

The location is, of course, one of the important facts to analyze. My previous article, Sea Piracy in 2025 analyzed the current trend of attack attempts very deep offshore …..or within non protected anchorage areas along the West African coast from Luanda till Abidjan.

This first enemy analysis realized, and to remind on the Sun Tzu citation, it may be even more important to know yourself. Turning back to the Gulf of Guinea piracy data, one element is alarming: it’s the number of vessels boarded without alarm/alert: No VHF.M distress call, no SSAS (Ship Security Alert System) alert, no vessel internal alert. The personnel on bridge duty discover the pirates when one is directly pointing a gun at them on the other side of the bridge glass.

For at least two cases in the last few months, the pirates have used….the pilot ladder left along the hull by night. These observation led to at least two main reflections: the seafarers had misjudged the threat and, because of this error, had not applied the adapted basic security measures.

Reviewing the current trends, appreciating more precisely the Gulf of Guinea pirates' modus operandi, it’s obvious that the area located between San Pedro and Luanda and taking a range of 200 nautical from the shore must be considered as High Risk Area for piracy. (Conakry Anchorage is a specific bubble which should be considered too.) This area is globally characterized on the specific chart established by the MDAT-GOG. Within this area, as said before, the pirates are currently acting on two modes:

Piracy attack deep/very deep offshore: Action is characterized by a direct attack against a vessel en route day or night. The detection of the threat is facilitated by the sparse maritime traffic, but the vessel is usually alone, not protected.

Maritime criminality within anchorage area: The pirates operate in discretion, by night against vessels anchored or on stand by. The detection of the threat is complicated by the numerous speed boats/canoes fishing in the area, but the vessel can benefit from security support from navy assets protecting the area.

The objective of these two pirates process is the same: kidnapping of crew members.

This being posed, and as the threat is focused on abduction, it is interesting to revisit the maritime operators possible internal self responses in 10 main actions:

• Secure the vessel as much as possible by a security escort vessel or an embarked military security team: The pirates are focusing on soft targets!

• Optimize your detection means for locating pirates as early as possible: One speed boat sailing 30 knots is along board six minutes after detection at three nautical miles!

• Be able to classify the threat as soon as possible, using the piracy criteria declined above: Personnel on duty on the bridge should be informed, trained and regularly refreshed about local pirates. Raise the alarm about the attack by all means available (VHF.M 16 / SSAS/ GMDSS/ PHONE / HORN-SIREN/LIGHT)

• Optimize internal alert systems to ensure all crew members will be aware of the alert sent. Conduct regular anti-piracy drills: piracy attack / alert / immediate communication / mustering / lock down control / anti-boarding measures / move to safe haven.

• As soon as you operate within a high risk area, lock your vessel. All external doors locked, all portholes secured. Try to slow down the pirates progression onboard the vessel after boarding by the use of specific items (wire rack or other) on external stairs.

• Use the navigation lights only, no deck light, all portholes blinded. By night level 4 or 5, when navigation lights are off, after change of course /speed, the vessel targeted disappears for pirates sailing onboard speed boat without radar, AIS or night vision goggles.

• Optimize the vessel's readiness by using simple and efficient systems. As the maritime industry is strongly impacted by the general economic situation, focus on low cost equipment rather than hoping for the use of means that are certainly effective but financially unaffordable. As an example, one general public autonomous sensor sending sound, light and possibly video, set up on the obliged path from deck to bridge, can efficiently alert the watchkeeping team in case of initial surveillance/detection failure.

• Consider the first internal door from navigation bridge to accommodations and lower decks as one essential element of your safe haven. Reinforce this door, reinforce the frame, complete the hardening with a mobile forestay. This first internal door will create an emergency initial secured bubble allowing a short time to alert and gather the crew in emergency in case of a late alert, pirates being already onboard. The four or five minutes it will take pirates to destroy this door will allow you to secure the full crew within the real final citadel.

Of course, this list is not exhaustive. It’s established on the analysis of hundred of maritime piracy acts within the Gulf of Guinea and is mainly dedicated to avoiding crewmembers being kidnapped. It can be completed and/or adapted depending of vessel configuration and the good sense.

LENOVO THINKPAD T490S LAPTOP REVIEW: THIN AND LIGHT DONE RIGHT

A SLIM LAPTOP WITHOUT THE USUAL COMPROMISES

The ThinkPad T490s (note the s) is a slimmer take on the already slim ThinkPad T490, both of which are 14-inch models in Lenovo’s current ThinkPad lineup.

It seems to fit somewhere between the standard T-series and ultra thin-and-light X-series laptops from Lenovo, and any way you look at it the T490s is a slim and very lightweight business machine.

Another aspect of the T490s is the variety of display options available, from low-power FHD panel of our review sample all the way up to a WQHD option featuring Dolby HDR support.

But the best part of this design? Though it carries the ubiquitous “thin-and-light” label, the T490s actually offers legitimate I/O support in the era of USB-C-only laptops.

T490S DESIGN

The case material is the familiar ThinkPad combination of carbon fiber-reinforced plastic and magnesium alloy, and this version of the T490s measures 12.94 x 8.85 x 0.63 inches and weighs just 2.81 lbs (there is some variance based on display panel configuration).

And now for a look at the all-important I/O, which is significantly above average with the ThinkPad T490s compared to other laptops in the “thin-and-light” category. No, it’s not quite up to the level of the full-sized T-series models, but we aren’t talking about yet another slim laptop with just a pair of USB-C ports, either.

From left to right we have the USB-C AC power input, USB-C Thunderbolt 3 port, Ethernet (requires optional Ethernet Extension Adapter), USB 3.1 Gen1 port, HDMI output (1.4), and 3.5 mm headphone/mic combo port.

On the other side we see, again from left to right, an ExpressCard slot for an optional Smart Card reader, another USB 3.1 Gen1 port (this one offering Always On power for charging), and a Kensington lock slot.

The rear of the T490s is where you’ll find this model’s combo MicroSD card reader/micro-SIM slot.

The front edge of the laptop’s lid houses the slider for the physical camera cover (ThinkShutter).

While this is a not a 360-degree hinge design like the Yoga series, this ThinkPad offers a hinge that allows the display to fold nearly flat:

Next up we’ll check out the all-important input.

INPUT

Long-time ThinkPad users have very strong opinions about their laptops, particularly when it comes to input. Here I decided to compare the T490s to recent ThinkPads and other thin-and-lights that I have used.

KEYBOARD

The keyboard is comfortably wide, with slightly concave key caps that help make these feel a bit more traditional. The key travel is still fairly shallow, but still deeper than most chiclet-style options out there. I found this model to feel almost exactly like my trusty ThinkPad Yoga S1’s keyboard, which is to say it’s very, very good.

The keyboard is also spill resistant (though I was not brave enough to test this out before I had to send it back), and our review unit featured LED backlighting. I really don’t have any complaints here.

ULTRANAV AND TRACKPOINT

The buttonless touch pad (UltraNav) offers a smooth multi-touch surface that feels good, though not up to the level of the large glass touch pads on Apple machines. That unpopular Apple reference aside this did feel quite good and was very responsive, and I had zero issues with it.

For its part the TrackPoint “nub” felt like any other ThinkPad’s TrackPoint I’ve personally used. Some people will prefer this method, and you do get physical buttons for left and right click at the top of the touch pad just below the space bar. Tracking felt as precise as ever.

I found myself favoring the TrackPoint for certain types of work including photo editing, while I defaulted to the touch pad for things like web browsing, where I appreciated the solid implementation of two-finger scrolling.

DISPLAY

Without doing a thorough analysis I can only offer subjective impressions here, and the low-power FHD display on our sample was excellent. It offers a matte surface that was pretty good at rejecting glare, but I was immediately struck by its rich color and what I thought was very good accuracy out of the box (especially for a business machine that isn’t marketed toward creative professionals).

Lenovo doesn’t provide specifics about the Low Power FHD panel in our sample, other than the fact that it is IPS. I have seen it suggested that they may be using IGZO technology for this low-power variant (in the Notebook Check review), and going all the way back to 2016 when I experienced my first IGZO display (with the Dell XPS 15) that seems right. There’s just something about the color, which I would describe as a quasi-OLED effect.

PERFORMANCE

I set out evaluating this laptop by simply using it as my daily driver for a few months. I used the T490s exclusively over this past summer (keen-eyed observers may have noticed a system date from way back in July in the photos of the system), and I continued to use the machine until the end of August.

This isn’t new information, but honestly there is nothing earth-shattering about performance numbers from a notebook with an 8th-Gen Intel Core i5 mobile processor. The most important aspects of a laptop (to me, anyway) have nothing to do with compute performance, and everything to do display and input quality – and of course battery life.

I did run the PCMark 10 Extended benchmark (and a couple of others) for reference, and provide the results below for anyone interested. One thing of debatable interest was the x264 benchmark, which I’ll admit right now is a terrible idea for a mobile benchmark – just like Cinebench. How many people are rendering or transcoding with their laptop? (Unless it’s their only PC, of course.)

After the first pass of the first iteration (of four consecutive) of the x264 benchmark, the CPU performance dropped considerably as thermal/power management kicked in (from the benchmark’s text output):

Pass 1

encoded 11812 frames, 79.49 fps, 7754.22 kb/s

encoded 11812 frames, 69.55 fps, 7754.21 kb/s

encoded 11812 frames, 69.32 fps, 7754.22 kb/s

encoded 11812 frames, 69.30 fps, 7754.32 kb/s

We’re talking a drop from 79.5 to 69.5 FPS immediately, which stabilized at around that 69 FPS number after that. What does this mean? It means don’t use a laptop for video transcoding unless you have to.

In closing, performance with an 8th Gen Core i5 processor is just fine for most tasks, and you only run into problems if you want to do something very CPU or GPU intensive – particularly the latter. There is no discrete GPU option with the T490s, and a Core i5-8265U processor limits you to Intel UHD 620 graphics. This isn’t going to take you very far up the resolution/detail settings ladder, but this is a business machine after all (though it runs DOSBox like a champ, which is all that really matters anyway).

CONCLUSION

I used a number of laptops in 2019, and this ended up being my overall favorite. No, it’s not a big gaming beast with a mechanical keyboard and desktop GPU inside, nor is it an impossibly slim aluminum lifestyle accessory with zero connectivity. The ThinkPad T490s exists in this happy medium of professional machines where at least some of the I/O we used to take for granted is still built in to the device itself, and doesn’t exist only in one’s imagination (aka a series of dongles).

Can it be argued that an extra-slim T-series machine from Lenovo is really a T-series machine, considering concessions to size such as the need for an optional adapter for Ethernet? I wasn’t hung up on the branding of the laptop, so I won’t argue either way. To me it was just a solid business-oriented laptop with a great display, great input, and great battery life. And it was super lightweight. What more can you really ask for from a work laptop?

Now we come to an aspect of the T490s that I didn’t get into in the review as I was evaluating a single variant of this model: there are a lot of different configurations available. A ThinkPad T490s as reviewed is about $1700, but a T490s actually starts at around $1399, and there’s even a T495s variant with AMD processors available now (starting at ~$1050).

I would certainly recommend that anyone check out this T490s/T495s product family if they are in the market for a lightweight productivity laptop that doesn’t require carrying around a series of dongles everywhere you go. The T490s might not be what long-time T-series users think of as a “T-series” laptop (it’s probably more like a thicker X-series), but regardless of the designation it’s a damn good laptop.

First Drive: 2019 Audi A8L

VALENCIA, SPAIN — Waking up the 2019 Audi A8 invokes a brief but dazzling light show where photons pulse across hundreds of LED and OLED elements within the headlamps and tail lamps. The fleeting welcome sequence flourishes with two blue glows adjacent to night-piercing laser diodes, the pièce de résistance of a sophisticated lighting system that uses GPS data to illuminate the next bend before the driver turns the steering wheel. Is this the future of the übersedan? The lighting is but a fragment of the startlingly advanced features Audi hopes will help make the A8 into the gotta-have-it German four-door. Welcome to the (remarkably complex) machine.

Enhanced, Automated

Fancy LEDs aside, the 2019 Audi A8’s prime push is its positioning as the first production car capable of level 3 autonomy—“conditional automation.” Audi’s autonomous tech alleviates the driver of the responsibility of monitoring vehicle controls as long as a physical barrier blocks vehicles from oncoming travel. The system, dubbed Traffic Jam Pilot, works from a standstill up to 37 mph and fully controls steering, throttle and brakes in nose-to-tail traffic. Though drivers shouldn’t need to intervene, Audi also says, “The driver must remain alert and capable of taking over the task of driving when the system prompts them to do so.” That is, as long as government agencies modify their policies in time to permit the technology when the car bows in fall of 2018.

Ahead of the Curve

You might not know it from the mild silhouette or subtly rendered proportions, but Audi’s new design language debuts in this A8—though it seems more like an exercise in extreme discretion than an outright discourse. There’s a smidge of sharpness on the edges of the character lines along the doorsills when viewed straight on (made possible from deep-drawn aluminum panels), but the prevailing theme here is one of gently chamfered edges and elegant understatement. The hexagonal grille may be imposingly large, but it also blends into the car’s front end unobtrusively.

The 2019 A8’s body-in-white is composed of four materials—aluminum, high tensile steel, magnesium, and carbon fiber-reinforced polymer—and claims lowest-in-class (but not yet specified) weight and up to 24 percent greater torsional rigidity than the outgoing model. Its dimensions grow 1.5 inches in length, between .5 and .7 inches in height, and .2 inches in wheelbase, while width shrinks by .2 inches.

Similar to Range Rover’s embrace of the term “reductionism” to describe the lack of ornamentation in its Velar, the A8’s minimalist thread carries inward, where wood, leather and aluminum form a layer cake of reassuringly authentic finishes that are, again, solid and stately, but lacking in drama. There’s a masculinity to the spacious cabin, though those rich tactile materials are interrupted by the door handles made of chromed plastic, an unfortunate counterpoint to the otherwise sincere materials throughout. At least their electrically actuated action is crisply satisfying.

The MMI interface as we know it has been replaced by a 10.1- and an 8.6-inch touchscreen, a system Audi calls MMI Touch Response. The haptic system works well, with subtle feedback and audible clicks, both of which are adjustable. While the top screen manages a vast number of settings from vehicle dynamics to navigation and multimedia, the bottom is dedicated to HVAC and seats—which, incidentally, offer some of the best, deepest chair massages in the industry. Rear passengers get reclining seats and a weighty, removable tablet that also controls an available heated, massaging footrest behind the front passenger seat. The starkness of the dashboard’s black panel screens is, thankfully, countered by a key selection of fixed touch sensitive buttons and dials—namely drive select mode, a volume knob, a stability control button, and HVAC vent controllers that offer additional micromanagement of fan speeds and can shut off the vents altogether, sliding them behind an electrically actuated panel for a clean look.

Driving Digital

Audi AI, the system that governs the autonomous driving and parking tech, is not yet avaialable in test cars, so we sampled the two gasoline-powered models confirmed for the U.S. market instead: the A8 55 TSFI, powered by a 340 hp, 368 lb-ft 3.0-liter turbo V-6; and the A8 60 TSFI, motivated by a 460 hp, 486 lb-ft 4.0-liter twin-turbo V-8. The V-6 will be available at launch, followed by the V-8 several months later. Don’t be surprised to see plug-in hybrid and W-12-powered variants down the line.

Quiet certainty is A8’s the modus operandi on the road, aided by a standard adaptive air suspension system that combines a smooth ride with comfort-focused but glued-down handling. The roads in and around Valencia were already eerily smooth, but perhaps more impressive than the ride quality was how the A8L defied its bulky proportions. The A8’s available all-wheel steering system countersteers the rear wheels as much as 5 degrees at lower speeds, easing turn-in and reducing turning radius by 3.3 feet. High-speed stability is bolstered by up to 2 degrees of parallel-phase rear steering. On the winding stretches of mountain overlooking the city, the A8L negotiated dramatically tight corners with relative ease, making it feel considerably smaller than its 123.1-inch wheelbase might suggest.

An optional active suspension will be available following market launch. The electromechanical suspension, dubbed Audi AI active, is powered by a 48-volt system that scans the road ahead and can not only lift each wheel by up to 2.3 inches in anticipation of a bump, it can also raise the body nearly 2 inches to aid body control. A staged demonstration showcased a startling ability to soak up a raised section of road, all but eliminating the impact of the offending bump. Observing the system externally reveals a visible lift in the body, the wheel wells becoming more exposed in anticipation of the suspension articulation. Neat. The system can also sense an impending side impact and raise the body up to 3.1 inches in a half-second in order to minimize injury. While Audi didn’t offer road tests of the electromechanical suspension, the parking lot demo offered a convincing argument for the technology.

The 3.0-liter V-6 delivers even, smooth power—0 to 62 mph arrives in a claimed 5.7 seconds—but the 8-speed auto plays so nicely with the mill that it rarely leaves the driver wanting for quicker acceleration. Engine noise comes in quiet, hushed tones thanks to the well-isolated body and double-paned glass. The 4.0-liter V-8 delivers the predictably more satisfying thump of torque that expedites forward movement (Audi has yet to provide an acceleration time), and active engine mounts help smooth out the powerplant’s reciprocating effect. The V-8 also runs rather quietly and gains active noise cancellation to help further dampen the acoustics, though keen listeners might appreciate the faintly audible thrum and the quiet, low frequency bottom note between shifts. Choose the right drive mode setting, and you’ll hardly ever question the computer’s gear selection; take over with the small, wheel-mounted paddle shifters, and you’ll get quick-enough cog swaps that can shift smoothly in milder settings or with a slight punch in dynamic mode.

Genius Seeks Soul

The A8L’s advances suggest Audi is hell bent on becoming the technical leader in the large, high dollar sedan segment. If you’re the type to geek out on whiz bang gizmos, it’s hard not to fall for the A8’s bag-o-tricks, which of course centers on self-driving and gains supported from the trick electromechanical suspension and features like a self-parking function that enables operation from outside the vehicle. But Audi’s latest flagship begs a deeper question about intangibles: this dizzyingly sophisticated machine packs a total of 24 sensors including six cameras, five radar sensors and one laser scanner, not to mention an array of microprocessors to orchestrate and execute the vehicle’s deep skillset. But does this technological tour de force inspire emotion? The A8L claims an impressive skillset and groundbreaking autonomy, but the million-dollar question might leave some traditional luxury lovers cold.

Seafarers Must Adapt to the Rapid Evolution of Piracy

As such, it would be interesting to test the captains/SSOs to make them draw Gulf of Guinea pirates. To help their sketches, we can try to characterize them by some elements:

The objective of these two pirates process is the same: kidnapping of crew members.

This being posed, and as the threat is focused on abduction, it is interesting to revisit the maritime operators possible internal self responses in 10 main actions:

• Secure the vessel as much as possible by a security escort vessel or an embarked military security team: The pirates are focusing on soft targets!

• Optimize your detection means for locating pirates as early as possible: One speed boat sailing 30 knots is along board six minutes after detection at three nautical miles!

François Morizur is a maritime security expert and former French Navy officer.
