Sometimes, I cringe; sometimes, I just listen and wonder. These past few months have given us all a lot to think about in the automotive space, and it's clear now that the coming years will keep the foot down on the accelerator when it comes to the dramatic changes we've experienced this past decade. One thing that stood out to me in various recent conversations is that there's a widening gulf opening between Chinese automakers and the rest of the world. This isn't exactly news, and this column isn't meant to monger any fears. It's just a bit of off-the-cuff reporting that sheds a bit of light on the level of the challenges we face. As you can read in Chris Clonts' excellent report further in this issue about the warning that Voltaiq's CEO gave at The Battery Show this October, the U.S. is in serious danger of falling well behind Chinese competitors in the EV battery race (Michael Robinette tackles similar ground through a tariff lens in this month's Supplier Eye). But that message was

Other system components for treating cabin air, such as filtration and humidification, are included, as are the ancillary functions of equipment cooling and cargo compartment conditioning
From televisions to smartphones, organic light-emitting diodes (OLEDs) are finding their way into many everyday devices. For use in displays, blue OLEDs are also required to supplement the primary colors — red and green. Especially in blue OLEDs, impurities give rise to strong electrical losses, which could be partly circumvented by using highly complex and expensive device layouts.
A unique wristwatch contains multiple modules, including a sensor array, a microfluidic chip, signal processing, and a data display system to monitor chemicals in human sweat. It can continuously and accurately monitor the levels of potassium (K+), sodium (Na+), and calcium (Ca2+) ions.
Validation plays a crucial role in any Electronic Development process. This is true in the development of any automotive Electronic Control Unit (ECU) that utilizes the Automotive V process. From Research and Development (R&D) to End of Line (EOL), every automotive module goes through a plethora of Hardware (HW) and Software (SW) testing. This testing is tedious, time consuming, and inefficient. The purpose of this paper is to show a way to streamline validation in any part of the automotive V process using Python as a driving force to automate and control Hardware-in-the-loop (HIL) / Model-in-the-loop (MIL) / Software-in-the-loop (SIL) validation. The paper will propose and outline a framework to control test equipment, such as power supplies and oscilloscopes, load boxes, and external HW. The framework includes the ability to control CAN communication signals and messages. A visual Graphical User Interface (GUI) has also been created to provide simplified operation to the user
Robots and cameras of the future could be made of liquid crystals, thanks to a new discovery that significantly expands the potential of the chemicals already common in computer displays and digital watches. The findings are a simple and inexpensive way to manipulate the molecular properties of liquid crystals with light exposure.
A research team led by Lawrence Berkeley National Laboratory (Berkeley Lab) has developed “supramolecular ink,” a new technology for use in OLED (organic light-emitting diode) displays or other electronic devices. Made of inexpensive, Earth-abundant elements instead of costly scarce metals, supramolecular ink could enable more affordable and environmentally sustainable flat-panel screens and electronic devices.
This SAE Standard specifies symbols (i.e. conventional signs) for use on controls, indicators, and tell-tales applying to passenger cars, light and heavy commercial vehicles, and buses, to ensure identification and facilitate use. It also indicates the colors of possible optical tell-tales, which inform the driver of either correct operation or malfunctioning of the related devices.
Imagine a thin, digital display so flexible that you can wrap it around your wrist, fold it in any direction, or even curve it over your car’s steering wheel. Well, imagine no more — researchers at the Pritzker School of Molecular Engineering (PME) at the University of Chicago have designed such a material; it can even bend in half or stretch to more than twice its original length — and still emit a fluorescent pattern.
More pixels! This is a major trend in the display industry. The benefits of 8K or higher resolution TVs may be debatable. For eye catching applications such as AR/VR glasses, more and therefore smaller pixels are required for technical feasibility. Screen door effects and pixel inhomogeneities are easily visible and disturbing for the user on displays that sit closely to the viewer’s eye. μ-LEDs are considered an innovative technology for very high resolutions with pixel sizes of less than 10 μm and equally small pixel pitches. In general, they have the potential to be a groundbreaking display technology – provided production challenges can be solved. Just like OLED displays, μ-LEDs are an emissive display technology, i.e., each single subpixel is in itself a light source. Luminance and color variations between the individual pixels are likely. As this strongly influences the visual quality of the displays, a quality control and calibration of the displays is necessary not only in the
Researchers have designed a thin, digital display that can bend in half or stretch to more than twice its original length while still emitting a fluorescent pattern. The material has a wide range of applications, from wearable electronics and health sensors to foldable computer screens.

An international team of scientists is developing an inkable nanomaterial that they say could one day become a spray-on electronic component for ultra-thin, lightweight, and bendable displays and devices.
The startup plans to apply lessons learned in Europe to the U.S. market, bringing a “small fleet” of electric trucks for potential customers by the end of the year. Volta Trucks has been operating its all-electric Volta Zero delivery trucks in Europe for three years. Now, the map is expanding. Fleet operators soon will be able to get behind the wheel of a Class 6 or 7 Zero in the U.S., adding to a growing list of electric options for moving freight. Volta displayed a Zero at the 2023 Advanced Clean Transportation (ACT) Expo in Anaheim, California, in May as a sort of ambassador. Volta will tour this truck around the U.S. for a few months before bringing over a “small fleet” for potential customers to test out and perhaps integrate into their operations before the end of the year, according to Volta Trucks CEO Essa Al-Saleh. It's all part of a dramatic shift towards electrification throughout the industry, he said.
Operating beyond the visible light spectrum, forward-looking infrared (FLIR) cameras use a thermographic imager (camera) that senses infrared radiation, or heat signatures. Advanced FLIR thermal imaging systems capture and display infrared wavelengths that are radiating energy. Infrared thermography consists of three specific wavelengths, including short-wave infrared (SWIR), midwave infrared (MWIR), and long wavelength infrared (LWIR). MWIR imaging cameras have long been the preferred solution for clear thermal imaging at distances greater than one kilometer (km) for defense, unmanned aircraft systems (UAS), counter-UAS, security, and other long-range surveillance applications. To meet these imaging requirements, advanced MWIR camera systems are commonly integrated with infrared telescopes that feature a continuous zoom (CZ) lens assembly. Developing custom cameras and CZ lenses can be costly in terms of time and resources, and it can become complicated.
SAE J1362 presents graphical symbols for use on operator controls and other displays on off-road work machines as defined in SAE J1116, plus mobile cranes, but excluding agricultural tractors. Symbols for agricultural tractors are covered by ASABE S304, ISO 3767-1, and ISO 3767-2.
SAE J2461 specifies the recommended practices of a Vehicle Electronics Programming Stations (VEPS) architecture.in a Win32® environment. This system specification, SAE J2461, was a revision of the requirements for Vehicle Electronics Programming Stations (VEPS) set forth in SAE J2214, Vehicle Electronics Programming Stations (VEPS) System Specification for Programming Components at OEM Assembly Plants (Cancelled Jun 2004). The J2214 standard has been cancelled indicating that it is no longer needed or relevant.
An ultrathin display for holographic images consists of a thin film of titanium filled with tiny holes that precisely correspond with each pixel in a liquid crystal display (LCD) panel. This film acts as a “photon sieve” — each pinhole widely diffracts light emerging from them, resulting in a high-definition 3D image observable from a wide angle.
ABSTRACT As U.S. Army leadership continues to invest in novel technological systems to give warfighters a decisive edge for mounted and dismounted operations, the Integrated Visual Augmentation System (IVAS) and other similar systems are in the spotlight. Continuing to put capable systems that integrate fighting, rehearsing, and training operations into the hands of warfighters will be a key delineator for the future force to achieve and maintain overmatch in an all-domain operational environment populated by near-peer threats. The utility and effectiveness of these new systems will depend on the degree to which the capabilities and limitations of humans are considered in context during development and testing. This manuscript will survey how formal and informal Human Systems Integration planning can positively impact system development and will describe a Helmet Mounted Display (HMD) case study.
Used in products ranging from brake lights to billboards, LEDs are ideal components for backlighting and displays in electronic devices because they are lightweight, thin, energy-efficient, and visible in different types of lighting. Micro LEDs, which can be as small as 2 micrometers and bundled to be any size, provide higher resolution than other LEDs. Their size makes them a good fit for small devices such as smartwatches but they can be bundled to work in flat-screen TVs and other larger displays. LEDs of all sizes, however, are brittle and typically can only be used on flat surfaces.
This SAE Aerospace Standard (AS) establishes the minimum standard requirements for message boards (MBs) at designated deicing facilities. The design of aircraft deicing facilities is covered by ARP4902. Standards for the deicing facility management system are outside the scope of this document.
A new device from Lincoln Laboratory can now alert trainees when they are heading toward injury. The device continuously estimates a person’s core body temperature to determine their risk level for heat strain as they train. This risk is communicated on a smartwatch display, providing early warning to its wearer.
Based on the success of the second-generation Genesis G80 model, Hyundai Motor has declared the independence of Genesis as a luxury car brand in 2015. The third-generation G80 is the representative model of the Genesis brand and has a unique identity of Genesis that can surpass its competitors. In addition, it was necessary to develop seats that were considered not only for ICE but also for the scalability of electric vehicles. A newly formed Genesis organization established the Genesis design philosophy of its own. Four key elements of the design philosophy were comfort, aesthetics, usability and safety. The third-generation Genesis seats incorporate its design philosophy of seat design and new technologies based on comfort, aesthetics, usability, and safety. This paper describes the seat development of the Ergo Motion seat, Rear Seat Relaxtion(Relax + Position), Seat Syling, AVN switch display and PSS(pre-active safety seat )system, which are representative technologies.
At CES 2022 Panasonic Automotive Systems Company of America unveiled AR HUD 2.0 (Augmented Reality Head-Up Display 2.0), the first system to include a new, patented eye-tracking system (ETS). If you've ever thought about what exists beyond the limits of a HUD and the small rectangular box it displays on the windshield, welcome to the world of AR. And note that AR is not VR, Virtual Reality; VR is a space in which headsets or special glasses allow the wearer to experience a 3D world that doesn't exist except in this technology. It's increasingly used in automotive interior design.
Researchers have developed an innovative display that shows information through clothes and other fabrics. The new technology, called PocketView, uses LED lights to display basic information. It can function as a standalone piece of technology or could be incorporated into existing or next-generation smart devices.
The SAE Recommended Practice is intended for use in measuring the radius of curvature (ROC) of spherical convex mirrors.
A hyphenated instrument is one that blends the capabilities of two different technologies to form a new analytical technique with novel abilities. The microscope spectrophotometer is one such hyphenated instrument; it is a hybrid that combines the magnifying power of an optical microscope with analytical proficiencies of a UV-visible-NIR range spectrophotometer. As such, microscope spectrophotometers can be used to measure the molecular spectra of microscopic sample areas from the deep ultraviolet to the near infrared region. They can be configured for many different types of spectroscopy and, as such, are used to measure absorbance, reflectance, and even emission spectra, such as fluorescence and photoluminescence, of micron-sized samples. With the addition of specialized algorithms, the microscope spectrophotometer can also be used to measure the thickness of thin films or act as a colorimeter for microscopic samples.
LCD (liquid crystal display) is the most widely used display technology. They are used for automotive, appliance, telecommunication, home appliance, industrial, consumer electronic, military etc. But LCD displays have some drawbacks, such as slow response, narrow viewing angle, lower contrast etc. One annoying phenomenon often complained about by users is image sticking.
This document considers the cooling of equipment installed in equipment centers, which usually consist of rack-mounted equipment and panel mounted equipment in the flight deck. Instances where these two locations result in different requirements are identified. This document generally refers to the cooled equipment as E/E equipment, denoting that both electrical and electronic equipment is considered, or as an E/E equipment line-replaceable-unit (LRU). The majority of cooled equipment takes the form of LRUs. The primary focus of this document is E/E equipment which uses forced air cooling to keep the equipment within acceptable environmental limits. These limits ensure the equipment operates reliably and within acceptable tolerances. Cooling may be supplied internally or externally to the E/E equipment case. Some E/E equipment is cooled solely by natural convection, conduction, and radiation to the surrounding environment. This document discusses specification requirements, system
Even small changes in a soldier’s surroundings could indicate danger. Now, a robot can detect those changes and a warning could immediately alert the soldier through a display in her eyeglasses. Researchers demonstrated in a real-world environment the first human-robot team in which the robot detects physical changes in 3D and shares that information with a human in real time through augmented reality. The human is then able to evaluate the information received and decide follow-on action.
