EMC/EMP filters and capacitor manufacturer, MPE, has appointed SACA Group as an authorised distributor specifically to serve customers who need small or occasional orders. This is the first time in its 95 year history that the Merseyside company will use a distributor for the UK market. It has come about as the company experiences an increase in business from its ...

TDK has added a wider choice of output voltages to its CUS400M range of 400Wmax medical power supplies, originally only available in 12V or 24V. The new options 15, 19, 28, 36 or 48V. 400W is available with forced cooling (30 minutes, 40°C ambient, 230Vac in, 50% duty). “The duration period of that peak is considerably longer than most products on ...

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 be applied during an operation, ...

Schaffner has introduced a series of filtered IEC mains input connectors designed not to compromise two MOPP (means of patient protection) safety precautions in medical equipment. Called FN9274, they have been designed according to Class II medical equipment standard IEC / EN 60601-1. The enclosure is plastic for higher dielectric strength insulation and C18 inlet receptacles do not have an earth pin ...

In tests conducted with Yamaguchi-University, Stanley Electric has achieved 99.9% ‘inactivation’ of Covid-19 virus SARS-CoV-2 using its aluminium nitride-based 265 nm UV-C leds. Inactivation here, said the company, is defined as the inability to multiply after exposure through damage to DNA and RNA. “10ml of virus solutions [5 x 105 PFU/ml] in dishes were irradiated with 265nm UVC LED at ...

GNSS antenna modules by Reyax are claimed to have smallest dimensions available today. The company’s GPS, Glonass, Galileo and BeiDo modules are now available from Manhattan Skyline. The RYS8830 is a small form factor, low power 1.8V UART/I2C interface GNSS antenna module, built on the high performance Sony CXD5605GF CXD5605AGF GNSS engine. It uses concurrent reception of GNSS systems for ...

U-blox has announced a module combining Bluetooth Low Energy 5.2 and dual Arm Cortex-M33 cores – M33 is Arm’s security-enabled small embedded core. Called Nora-B1, at 10.4 x 14.3 x 1.8mm the modules are tiny, and they operate at up to 105°C for industrial and outdoor lighting use. Bluetooth and MCU cores are supplied by a Nordic Semiconductor nRF5340 chip, around which ...

OmniVision is sampling extensions to its OVMed medical image signal processor (ISP) family endoscopes and catheters called OH0120 and OH0130. The OH0120 provides an off-the-shelf, board-level option with HDMI connectivity and LCD screen support, as well as external USB memory-card storage. The OH0130 supports all of OmniVision’s HD and analogue medical image sensors, enabling customers to expand to full HD ...

AMS has introduced what it describes as the industry’s thinnest dedicated sensor for blood oxygen saturation (SpO2) measurement, the AS7038RB.   The sensor specialist and analogue chip supplier says it has the capability to remotely monitor this vital sign in small consumer products, such as earbuds, smart watches and wristbands. This is in addition to medical devices such as patches ...

French research lab CEA-Leti has created a novel x-ray photon-counting detector module (PCDM) for CT scanners, based on cadmium telluride (CdTe). CT scanners computer-process combinations of many X-ray images taken from different angles to produce 3D data. “Current x-ray CT scanners produce images with energy-integrating detectors [EIDs], which are based on indirect conversion technology: X-ray photons are first converted into visible light using ...
