UK made: PXI test module simulates current loop sensors

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 ...

Stronger haptic feedback for unambiguous automotive control

Alps Alpine has revealed more about its high-power haptic vibrator, following Dialog Semi’s announcment of the driver chip inside it yesterday. Haptic Reactor Heavy Type is intended for touch feedback, primarily in automotive applications. “There is currently growing demand for vibrational feedback, which allows more intuitive control and does not require any shift of gaze,” according ...

Machine learning finds heart faults

Russian and US scientists have used machine learning to find ‘atrial fibrillation (AF) drivers’ – small patches of faulty heart muscle that can cause cardiac arrhythmia. The team tested their approach on 11 donated human hearts and located AF drivers with an accuracy of up to 81%. Multi-electrode mapping (MEM) is a technique that can ...

Wrist-wearable ref design measures blood oxygen, ECG, heart rate, temperature and activity

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 , ...

How to half the size of electrolytics in universal ac-dc PSUs

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 ...

Maxim majors on industrial automation with new parts and designs

Maxim has announced a suite of integrated circuits and reference designs for industrial automation using IO-Link communications. IO-Link is a short-range (<20m) point-to-point industrial bus developed to connect sensors and actuators to a local hub, from which the data is transferred to a remote PLC (programmable logic controller) via Ethernet or other long-range field bus. ...

Toshiba CMOS op-amp draws only 0.27μA

Toshiba has released an micro-power CMOS operational amplifier, drawing a maximum of 600nA and typically 270nA (1.5V supply, -40 to 105°C). Called TC75S102F, it will run from supplies between 1.5V and 5.5V and is rail-to-rail on both input and output. Unusually for an op-amp, no input excursion outside the rails is allowed at all. “Operational amplifiers have ...
