Toyota 2nd Generation ADAS Changes Sensor from ON Semi to Sony

Nikkei: The second generation of "Toyota Safety Sense" (TSS2) ADAS switches to Sony image sensors in its monocular camera. The TSS2 was launched in 2018. The automatic braking function of the TSS2 (one of the main functions of the system) now can detect pedestrians at night. The new low light functionality is said to be enabled by higher DR of Sony sensors and by multiple image combination to increase signal.

Film-Based Light Sensing Review

University of Toronto repo publishes a Nature paper from January 2017 "Solution-processed semiconductors for next-generation photodetectors" by F. Pelayo García de Arquer, Ardalan Armin, Paul Meredith, and Edward H. Sargent. " Efficient light detection is central to modern science and technology. Current photodetectors mainly use photodiodes based on crystalline inorganic elemental semiconductors, such as silicon, or compounds such as III–V semiconductors. Photodetectors made of solution-processed semiconductors — which include organic materials, metal-halide perovskites and quantum dots — have recently emerged as candidates for next-generation light sensing. They combine ease of processing, tailorable optoelectronic properties, facile integration with complementary metal–oxide–semiconductors, compatibility with flexible substrates and good performance. Here, we review the recent advances and the open challenges in the field of solution-processed photodetectors, examin...

Microsoft Proposes Government Regulation of Facial Recognition Use

Microsoft President Brad Smith writes in the company blog : " Advanced technology no longer stands apart from society; it is becoming deeply infused in our personal and professional lives. This means the potential uses of facial recognition are myriad. Some emerging uses are both positive and potentially even profound. But other potential applications are more sobering. Imagine a government tracking everywhere you walked over the past month without your permission or knowledge. Imagine a database of everyone who attended a political rally that constitutes the very essence of free speech. Imagine the stores of a shopping mall using facial recognition to share information with each other about each shelf that you browse and product you buy, without asking you first. Perhaps as much as any advance, facial recognition raises a critical question: what role do we want this type of technology to play in everyday society? This in fact is what we believe is needed today – a government init...

Synaptics Under-Display Fingerprint Scanner Reverse Engineering

SystemPlus Consulting publishes a reverse engineering report of Synaptics’ under-display fingerprint scanner found inside the VIVO X21 UD Smartphone: " This scanner uses optical fingerprint technology that allows integration under the display. With a stainless steel support and two flexible printed circuit layers, the Synaptics fingerprint sensor’s dimensions are 6.46 mm x 9.09 mm, with an application specific integrated circuit (ASIC) driver in the flex module. This image sensor is also assembled with a glass substrate where filters are deposited. The sensor has a resolution of 30,625 pixels, with a pixel density of 777ppi. The module’s light source is providing by the OLED display glasses. The fingerprint module uses a collimator layer corresponding to the layers directly deposited on the die sensor and composed of organic, metallic and silicon layers. This only allows light rays reflected at normal incidence to the collimator filter layer to pass through and reach the optical ...
