A bio-inspired vision sensor that can detect spectrally distinctive features
Posted by Saúl Morales Rodriguéz in categories: robotics/AI, transportation
The ability to detect objects in settings with unfavorable lighting, for example at night, in shadowed locations or in foggy conditions, could greatly improve the reliability of autonomous vehicles and mobile robotic systems. Most widely employed computer vision methods, however, have been found to perform under poor lighting.
Researchers at the Hong Kong Polytechnic University recently introduced a new bio-inspired vision sensor that can adapt to the spectral features of the environments it captures, thus successfully detecting objects in a wider range of lighting conditions. This newly developed sensor, introduced in a paper published in Nature Electronics, is based on an array of photodiodes arranged back-to-back.
“In a previous paper in Nature Electronics, we presented a simple in-sensor light intensity adaptation approach to improve the recognition accuracy of machine vision systems,” Bangsen Ouyang, co-author of the paper, told Tech Xplore.

Tesla chooses interesting location for Robotaxi unveiling event
Posted by Genevieve Klien in categories: Elon Musk, sustainability, transportation
Tesla has reportedly chosen its location for the Robotaxi unveiling event on October 10, and it is quite interesting.
According to a new report from Bloomberg, citing people familiar with the matter, Tesla is planning to show off its new Robotaxi platform, along with “a few other things,” at the Warner Brothers Studio in Burbank, California.
Tesla initially planned to hold its unveiling event on August 8, but it was pushed back to October 10 due to a request for a front-end design change by CEO Elon Musk, who also hinted there would be more to show at the event with the delayed date.

Ultracompact fiber-tip sensor achieves high sensitivity in magnetic field and temperature measurements
Posted by Saúl Morales Rodriguéz in categories: biotech/medical, transportation
Magnetic field sensing plays a pivotal role in numerous fields of medical, transportation and aerospace. The optical fiber-based magnetic field sensor possesses outstanding characteristics of compactness, long-distance interrogation, low cost and high sensitivity, which has attracted intensive interest. However, the fiber-based magnetic field sensor is generally affected by the temperature perturbation.

Study of disordered rock salts leads to battery breakthrough
Posted by Shailesh Prasad in categories: engineering, mobile phones, nuclear energy, sustainability, transportation
For the past decade, disordered rock salt has been studied as a potential breakthrough cathode material for use in lithium-ion batteries and a key to creating low-cost, high-energy storage for everything from cell phones to electric vehicles to renewable energy storage.
A new MIT study is making sure the material fulfills that promise.
Led by Ju Li, the Tokyo Electric Power Company Professor in Nuclear Engineering and professor of materials science and engineering, a team of researchers describe a new class of partially disordered rock salt cathode, integrated with polyanions—dubbed disordered rock salt-polyanionic spinel, or DRXPS—that delivers high energy density at high voltages with significantly improved cycling stability.

Solid-state electrolyte advance could double energy storage for next-gen vehicles
Posted by Shailesh Prasad in categories: chemistry, energy, sustainability, transportation
Using a polymer to make a strong yet springy thin film, scientists led by the Department of Energy’s Oak Ridge National Laboratory are speeding the arrival of next-generation solid-state batteries. This effort advances the development of electric vehicle power enabled by flexible, durable sheets of solid-state electrolytes.
The sheets may allow scalable production of future solid-state batteries with higher energy density electrodes. By separating negative and positive electrodes, they would prevent dangerous electrical shorts while providing high-conduction paths for ion movement.
These achievements foreshadow greater safety, performance and energy density compared to current batteries that use liquid electrolytes, which are flammable, chemically reactive, thermally unstable and prone to leakage.
