Pepperl+Fuchs has combined laser pulse ranging and piezoelectric 2D scanning to create 3D point clouds. Adopting mems scanner technology from the Fraunhofer Institute for Silicon Technology (Fraunhofer ISIT), the proof-of-concept, dubbed R3000, sweeps a 40° x 30° cone at ranges “from a few centimetres to several hundred meters with millimetre accuracy,” according to P+F. “Ambient light and other environmental influences ...

For monitoring X-ray doses in patients undergoing radiotherapy for gastrointestinal cancer, a group of researcher have created a prototype swallowable dosimeter capsule that also measures gut pH and temperature. “The researchers found that the dosimeter was approximately five times more accurate than standard methods for dose determination,” according to the Chinese Academy of Sciences, whose Shenzhen Institute of Advanced Technology ...

Mouser Electronics has been announced as a sponsor for Nordic Semiconductor‘s Connect for Good: Low Power Wireless Sustainability Challenge, in association with Wevolver. The challenge is open to all engineers and students, ages 18 and up, with sufficient engineering capability to develop a working prototype that uses low power wireless technology to tackle one (or more) of the UN’s sustainable ...

LEM has created a current sensor specifically for Coulomb counting in electric vehicles. CAB 1500 is an automotive grade open-loop flux-gate transducer, intended to comply with ISO 26262 ASIL C functional safety. Range is ±1.5kA and the sensor is compatible with 800V applications to IEC 60664-1. Galvanic isolation is up to 2.5kV, and total error over -40 to +85° is ...

We caught up with Panasonic Industry in Nuremberg at Embedded World 2023 as part of our promotional coverage for the event. Benno Kirschenhofer – Communication Manager, Corporate Marketing Division, Panasonic Industry Europe GmbH – discusses being involved in the connectivity ecosystem that makes a smart world more sustainable, part of the company’s green impact initiative. He covers polarised power relays, ...

As alternatives to through-hole TO-39 or TO-18 packaged PIN diodes, Marktech Optoelectronics has announced hermetic surface-mount InGaAs PIN diodes sensitive to 1.7 or 2.6μm, protected against water vapour, oxygen and other gaseous contaminants. “The Atlas brand package is designed to deliver performance and reliability for applications including aerospace, medical, defence, wearables and industrial,” according to New York-based Marktech. “In addition, ...

Timing devices provide a mission-critical function in automotive systems. Even if a component or system goes awry, EMS clocking signals must continue operating without fail, says Etienne Winkelmuller, of SiTime. Vehicles are designed to work reliably for many years while operating in harsh conditions. If a component or system malfunctions, the vehicle is still expected to operate safely and reliably ...

Rohm has announced a high-side current sensor with a -0.2 to +26V input common-mode range and ±1.0% maximum gain error. Packaged in a 2.9 x 2.8 x 1.25mm SSOP6, BD14210G-LA senses voltage across an external high-side resistor and transfers this to a voltage relative to the 0V rail with a fixed gain of 20. Max offset is ±0.6mV (refered to ...

Allegro MicroSystems has announced an ASIL C safety rated magnetic field beased current sensor for electric vehicle power trains and automotive battery management systems. The company “has developed the ACS37601 programmable linear Hall-effect current sensor IC with over-current, over-temperature and self-test capabilities,” it said. The part “is Allegro’s highest-accuracy field current sensor for applications requiring measurement capability greater than 200A”. ...

Semiconductors drive three trends to maximise productivity and reduce energy consumption in factories and cities, says Amichai Ron of Texas Instruments. Higher levels of automation and control through more efficient systems maximise productivity and small innovations at the component level can result in meaningful cost, energy and time savings at the system level. There are three consistent trends, across industrial ...
