The envisioned reader of blood alcohol content (BAC) will be small, as part of the button that turns the car on. If the driver is inebriated, the car won’t budge, even after the driver hits this “start” button.TruTouch, is a company that defines its specialty as noninvasive biometric intoxication detection systems. Its product for this automotive application has an infrared light. The optical touch pad transmits light into the skin via direct contact and collects a portion of the light reflected back by the skin. This signal is analyzed to determine the alcohol concentration and verify the user’s identity. The device’s test is said to be as accurate as a blood test. Takata is aiming to get the cost down to approximately $200 each. © 2011 PhysOrg.com (PhysOrg.com) — TK Holdings Inc., a subsidiary of Takata Corporation of Japan, manufacturers of safety belts and airbag modules, will partner with TruTouch Technologies to create an in-car detection device that can tell if the driver is too drunk to drive. The device will check out the driver’s blood alcohol level through the skin of the finger. The finger-scanning device is seen as a nonintrusive but reliable way to keep drunk drivers off the road. Explore further To move the product further into development, the two companies partnering for this device have received a $2.25 million grant from the National Highway Traffic and Safety Administration (NHTSA) through the Driver Alcohol Detection System for Safety (DADSS) and the Automotive Coalition for Traffic Safety (ACTS).As for accuracy, observers say it would be a step up from the breathalyzer test, which can yield false positives. The Takata-TruTouch device could be on the market in eight to ten years. According to the NHTSA, the technology could be voluntarily installed as a new-car option.Skeptics ask if a voluntary, not mandatory, solution of this type will bring any meaningful change in the numbers of road accidents caused by drunk drivers. Nonetheless, supporters say the device may signal a new era in safety against drunk drivers.In 2009, close to 11,000 Americans, or one every 48 minutes, were killed in drunken-driving accidents, or 32% of the country’s total motor vehicle traffic fatalities, according to NHTSA data.As part of further product development efforts, the goal is to reduce processing time and to function not just at room temperature but under hot and cold temperatures and with different humidity and vibration levels. In future, cars might decide if driver is drunk The TruTouch Guardian device.

Citation: Single-inlet electric vehicle charging to showcase in LA (2012, May 5) retrieved 18 August 2019 from https://phys.org/news/2012-05-single-inlet-electric-vehicle-showcase-la.html (Phys.org) — Big names in global car manufacturers have announced a common method for charging electric vehicles. The companies are in agreement with a common charging technology for use on electric vehicles in Europe and the United States. The new method will provide special convenience by enabling car owners to charge their EVs using AC or DC from a single inlet. The charging system will allow for both alternating current and faster direct current charging on the same port. Another feature of the new system is that the charge can be done in faster time; a battery charge will take only 15 to 20 minutes. Explore further Seven auto manufacturers collaborate on harmonized electric vehicle fast charging solution Audi, General Motors, BMW, Chrysler, Daimler, Ford, Porsche, and Volkswagen are the automakers who support the technology, which will be showcased next week at the Electric Vehicle Symposium (EVS) in Los Angeles, from May 6 to May 9.The first vehicles to use the system are expected next year. Vehicles are already in development that will be capable of using the new system. The charging solution is titled “DC Fast Charging with a Combined Charging System” or Combined Charging System, for short. An EVS statement says this is a step forward in reducing complexity with its combined AC and DC charging. “One vehicle inlet, one control logic, one communication path, and one electric architecture.” The LA event will show vehicles and charge pumps for the Combined Charging System. According to reports, the system was developed for all international vehicle markets. Uniformity was key, with identical electrical systems, charge controllers, package dimensions and safety mechanisms.Numerous auto blogs point to the announcement as good news for an EV industry trying to achieve wider consumer adoption by coming up with practical solutions for battery charging. Car buyers understandably are skittish about not having available charging opportunities on longer drives or about charging waits. The new method takes15 to 20 minutes to power up a car using a similar standard.The charging system integrates one-phase AC-charging, fast three-phase AC-charging, DC-charging at home and ultra-fast DC-charging at public stations into one vehicle inlet. The International Society of Automotive Engineers (SAE) has chosen the Combined Charging System as a standard that incrementally extends existing Type 1-based AC charging The standard is to be officially published this summer. ACEA, the European association of vehicle manufacturers, has chosen the Combined Charging System as its AC/DC charging interface for new vehicle types in Europe as of 2017.According to a Chrysler release, the timeline is as follows: Commercially available combined charging units are projected for later this year. All committed OEMs have vehicles in development that will use the Combined Charging System. The first vehicles to use this system will reach the market in 2013. © 2012 Phys.Org This document is subject to copyright.

The researchers, led by Professor Joel K.W. Yang, at A*STAR (the Agency for Science, Technology and Research) in Singapore, the National University of Singapore, and the Singapore University of Technology and Design, have published a paper on the new technique for realizing 3D full-color stereoscopic prints in a recent issue of Nature Communications.”We have created possibly the smallest-ever stereoscopic images using pixels formed from plasmonic nanostructures,” Yang told Phys.org. “Such stereoscopic images do not require the viewer to don special glasses, but instead, the depth perception and 3D effect is created simply by viewing the print through an optical microscope coupled with polarizers.”The work is based on the concept of surface plasmon resonance: metal nanostructures can scatter different wavelengths (colors) of light due to the fact that the tiny nanostructures themselves resonate at different wavelengths. If a nanostructure is circular, its resonance is polarization-independent because the diameter of the circle is the same from all directions. However, if a nanostructure is biaxial (such as an ellipse or rectangle), its resonance will depend on the polarization of the incident light. By tailoring the exact dimensions of the biaxial nanopixels, researchers can generate different colors under different polarizations.Building on these ideas, the researchers in the current study have demonstrated that polarization-sensitive nanopixels that encode two sets of information can be used to produce 3D stereoscopic microprints. To do this, the researchers created nanopixels out of tiny pieces of aluminum a hundred or so nanometers across. The scientists experimented with nanopixels in two different shapes: elliptical and coupled nanosquare dimers (a pair of squares separated by a very small gap). This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. To demonstrate how these nanopixels could enable high-resolution 3D color microprints, the researchers designed a stereoscopic image containing stars on a 2D sheet by overlaying two slightly displaced views of the same image onto the same area. Then they added an x- and y-polarizer to the eyepieces of a microscope. Viewing the microprint through this stereomicroscope reveals a different image for each polarization, and the combined images appear as a 3D image.In addition to 3D prints, the polarization-sensitive nanopixels could have several other applications.”One can envision application of these prints to high-density optical information encoding or holography,” Yang said. “3D security elements that are difficult to replicate, and which offer different levels of authentication, could also be generated for anti-counterfeiting and anti-forgery technologies.”The researchers also note that it’s possible to make pixels that can encode not just two, but three or more images in a single pixel. For example, nanostructures that have circularly asymmetric shapes could have more than two polarization-dependent resonances due to the additional circularly polarized dimension. The researchers also plan to take steps toward commercialization.”Moving forward, there is much interest in developing techniques for creating such prints with significantly lower cost and higher throughput, both of which are imperative for this technology to be implementable at an industrial level,” Yang said. More information: Xiao Ming Goh, et al. “Three-dimensional plasmonic stereoscopic prints in full color.” Nature Communications. DOI: 10.1038/ncomms6361 Because these shapes are biaxial, they exhibit plasmonic resonances at different wavelengths for each axis, with the colors determined almost entirely by the dimension of the axis parallel to the polarization direction. For example, a 130-nm x 190-nm elliptical pixel appears green under y-polarized light and purple under x-polarized light. Comparing the two pixel shapes, the researchers found that the elliptical pixels have a broader range of polarization-dependent colors, while the nanosquare dimer pixels have lower levels of cross-talk, minimizing unwanted mixing of colors.

Each pixel can exhibit one of two colors depending on the polarization of the light used to illuminate it. So by viewing the pixels under light of both polarizations, two separate images can be seen. If the two images are chosen to be slightly displaced views of the same scene, viewing both simultaneously results in depth perception and the impression of a 3D stereoscopic image. © 2014 Phys.org (Left) Elliptical and coupled nanosquare pixels scatter different wavelengths of light depending on polarization.

Chai being the common accomplice to any conversation in all strata holds a very recognisable space. Also Read – ‘Playing Jojo was emotionally exhausting’Says Seema Kohli, “While painting I can hold my conversation intact with my canvas and me. I have used teacups and the idea of tea as a means of introspection, leading to final liberation. It holds an important dialogue between me and my inner, my outer, my social and my spiritual world. Hence the need for this installation.”The Cheekka holds cutting tea glasses with tea lights in it. The size of the installation can be increased or decreased according to the space allotted. The materials used include metal wire, glass, acrylic colour and tea. Also Read – Leslie doing new comedy special with NetflixSeema Kohli’s art practice involves various disciplines from drawing, painting, sculptures, installations and performance. The most significant one to emerge is ‘Performance Art’. Decay, hybridisation and transformation: Creating new identity; reshaping belongings; intimacy; a dialogue of matter and memory, all these constitute the language of her work.‘Time’ as a factor, is central to her practice, whether it’s a wrapped object or a performance. She uses time as medium, which is extended, assembled and captured. The aspects of continuity, repetition, vulnerability, duration, temporality, awareness, situation and public involvement are also inherent qualities that inform her art practice. The process before and after the performance is equally important and challenging.
