SiFive has created a PC-style motherboard as part of a platform for native Risc-V code development that “enables developers to create the Risc-V-based software they need for Risc-V platforms”, it said. “From real-time operating systems to custom Linux distributions, and the compilers, libraries, and applications that go with product design. Called ‘HiFive Unmatched’, at its ...

Essex-based Pickering Interfaces has announced a PXI-based module that simulates current loop based sensors in industrial control applications – a PXIe version is also available. Called ’41-765 Analog output/current loop simulator’, it is intended to tests transceivers using 4-20mA current loops. In addition, is also simulates other interfaces including 0-24mA, +/-24mA, 0-5V, +/-5V, and +/-12mV. A channel ...

Maxim is measuring blood oxygen, ECG, heart rate, body temperature and activity data in its third generation of wearable health monitor reference design, this time entirely wrist-worn. Called Health Sensor Platform 3.0 (aka MAXREFDES104#), it comes in a ready-to-wear wrist form with algorithms to provide heart rate, heart-rate variability (HRV), respiration rate (RR), SpO2 , ...

In a nice example of lateral thinking, Power Integrations has found a way to halve the space needed for electrolytic reservoir capacitors in universal mains ac-dc PSUs up to 65W. It relies on automatically switching a low-voltage capacitor in parallel with a high voltage capacitor, springing from the observation that, for the same amount of ...

Luminescent solar concentrators are sheets that collect light at various wavelengths and re-emit it at a wavelength better matched to a solar cell. They can be created in various geometries – for example a flat sheet can be arranged to collect light over its large surface, and then re-emit it from one edge to a ...

IAR Systems Embedded Workbench C/C++ compile and debug toolchain can now generate position-independent code and position-independent data for Renesas’ RH850 automotive MCUs. “The added functionality is useful in systems where applications are loaded dynamically,” according to IAR. “When using position-independent code and read-only data [ROPI], the compiler will generate code that uses PC-relative references for ...

Following on from an ultra-quiet 8mm tact switch in May, C&K has launched a ‘soft sound’ 12mm mid-travel tact switch, also aimed at automotive use. Called the SFS 12 Series, they are designed to have a positive haptic feeling and last for at least 300,000 cycles (1million cycles disconnected). There is a choice of actuation force: ...

University of Cambridge spin-out Flusso has launched what it claims to be “the world’s smallest flow sensor” – with a 3.5 x 3.5mm footprint. Called FLS110, it is a CMOS device designed for gas flow measurements, with gas entering and leaving through two tubular stubs. Flow range is up to 200cm3/min directly through the sensor, ...
