Mentor aims at automotive functional safety with tool ecosystem

Mentor is addressing the functional safety requirements of ICs in autonomous vehicles with an initiative called ‘Tessent Safety Ecosystem’ which links the firm’s own functional safety tools, including those acquired when it bought Austemper, to those from external partners – notably Arm through its Functional Safety Partnership Program. At the same time, it announced a related ...

20A 40Vdc EMI filters for MIL-COTS applications

TDK-Lambda has announced quarter brick EMC filters with a rating of ±40Vdc at 20A and a choice of flanged or non-flanged baseplates. Called the FQA series, they are intended for harsh and demanding environments including MIL-COTS vehicle and airborne. Differential and common mode noise attenuation is described as sufficient to simplify system level compliance to MIL-STD-461G by the firm, ...

Transceiver self-tunes to add DWDM to fibre

ProLabs of Cirencester has unveiled a plug-and-play optical fibre transceiver that can add DWDM to existing network infrastructure. Called Clarity Auto-Tuneable DWDM Transceiver, it plugged into the host device and passive mux, and is compatible with any OEM switch platform that supports SFP+ transceivers including switch platforms that do not natively support tuneable transceivers. The transceivers ...

AI processor is task parallel and thread parallel

Californian chip-maker Blaize has emerged from stealth development with a processor aimed at artificial intelligence. Until recently called Thinci, the El Dorado Hills firm describes its product as “the first true graph-native silicon architecture and software platform built to process neural networks and enable AI applications with unprecedented efficiency”. Unfortunately: “we are not disclosing any ...

Shared tooling means custom backlights for less

Cornish optical firm OMC is looking to cut the cost of custom moulded backlights for customers seeking medium quantities. The scheme is called ‘Mouldshare’, and it does what it says on the tin – a single moulding tool is made to manufacture parts for multiple customers. “In general, setup costs for standard moulded backlights are ...

3D printed conductors inside 3D printed solids offer little resistance

Engineers at Rutgers University are claiming 11.8μΩ.cm for conductors printed inside plastic structures, created by printing a novel silver ink and exposing it to high intensity light. The ink has both silver nano-wires and silver nano-spheres within it. These are fused using ‘intense pulsed light sintering’ with a xenon lamp, that is brief enough not to ...

Inorganic perovkite solar cell lasts longer

Perovskite solar cells can be made in open air and “last for months rather than days with a solar conversion efficiency slightly above 12%” according to Rice University if some of the Pb is replaced with indium. The switch also reduces defects that skew the cell’s bandgap. “From our perspective, this is something new and ...

Laser hacks hacks smart-speaker from 100m, opens house doors

University researchers have remotely gained control of a home smart speaker using a laser. The hack worked at a range of 110m, and would have been further if the team had had more space. All that was needed was a 5mW laser (little more than pointer-power) and a telescope (actually a telephoto lens). 60mW was sufficient ...

Fraunhofer secure’s local AI processing for sensors

Secured sensor processing using local artificially intelligence is the aim of a chip announced by Fraunhofer Institute for Microelectronic Circuits and Systems (IMS), which has developed it around an open-source Risc-V core. “In combination with the AIfES framework for embedded AI we have enabled a system for the application of artificial intelligence on sensor and actuator-related ...

ADC offers multi-microphone beam-forming to ease host processor load

Texas Instruments is aiming at beam-forming microphones with four-channel ADC that can connect to four analogue microphones or eight digital microphones, or a combination of the two. “Smart home systems face challenges with far-field audio capture,” according to TI. “In today’s systems, a limited number of microphones and restricted signal processing capability make it difficult ...
