Illustration of a pulse tube refrigerator. Credit: S. Kelley/NIST By modifying a refrigerator commonly used in both research and industry, researchers at the National Institute of Standards and Technology (NIST) have drastically reduced the time and energy required to cool materials to within a few degrees above absolute zero. The scientists say that their prototype […]
It enables small module designs with reduced component count for improved safety and electrification: high voltage interlocks, charging flaps, seatbelts, hood/trunk, gear tooth sensing, or brake-by-wire applications. For traditional safety automotive latches and switches, ranging from door and boot/trunk handles to seatbelts and brake light switches, the standard design uses a mechanical contact or […]
“Embedded AI is becoming increasingly important for safety-critical real-time applications,” said Infineon. “However, this also creates new requirements and standards that must be considered during the complete product lifecycle.” The TC4x family includes ‘PPU’ (parallel processing unit), an AI-accelerator intended to be ASIL-D compliant and aimed at motor control, battery management, vehicle motion control and […]
Radial flux AC motors offer some performance and packaging benefits but also bring some thermal and manufacturability issues. Part 1 of this series examined the axial-flux motor (AFM) in detail and compared it to the very widely used radial-flux motor (RFM). Part 2 of this FAQ continued the exploration of AFMs and RFMs. This final part […]
The hardware, called ‘VISC’, is an accelerated RISC-V core that “optimises complex mathematical algorithms for parallel execution in its reconfiguration hardware engine”, according to Red, which claims: “The VISC ISA [instruction set] enables developers to describe complex algorithms in just a fraction of the code size it would take with the standard RISC-V instruction set, […]
6.5 billion semiconductor sensors for automotive applications were shipped last year generating revenue of $9.3 billion and demand is pointing to a 9 billion unit market with revenue of $14.3 billion by 2029 at a 7% CAGR between 2023 and 2029. “The upcoming years are poised to witness a dynamic transformation in automotive sensor technology […]
The kit comes with pre-loaded configurable firmware, eliminating the need for firmware development, and replacing it with straightforward calibration and configuration through a GUI. LED lighting, especially when implemented in a highly dynamic manner, is increasingly recognized as a key element of modern automotive design. It creates striking visual differentiation, helping manufacturers to make their […]
Generative artificial intelligence (AI) requires rapid and continuous movement of large amounts of data. In a growing number of instances, electrical input/output (I/O) connections between the ICs in chiplets are becoming a bottleneck to higher performance. Key electrical I/O performance barriers include power efficiency, bandwidth, and latency. This FAQ looks at the anticipated benefits of […]
