Infineon has teamed up with Reality AI to give vehicles a sense of hearing. “This solution enables cars to ‘see’ around the corner and to warn about moving objects hidden in the blind spot or approaching emergency vehicles, cars and other road participants, even if they cannot be seen by driver or detected by the sensors incorporated in the vehicles’ ...

Allegro has created a 3d magnetic sensor that can perform rotary and translation motion measurement both on-axis and off-axis (see diagram). Called A31315, it includes configurable signal processing, linearisation and angle calculation allows it to resolve the absolute rotary or linear position of a moving magnetic target. It has “excellent native angle error over temperature in any plane: <1.2° over -40°C to ...

Adlink Technology has launched an industrial smart camera series that integrates an Nvidia Jetson Xavier NX module for artificial intelligence processing. Called Neon-2000-JNX “the camera’s high performance, small form factor and ease of development open the door for AI vision solutions in manufacturing, logistics, retail, service, agriculture, smart city, healthcare and life sciences, and other edge applications,” claimed Adlink. “The ...

Melexis,  the Belgian fabless IC company, is targeting white goods, consumer electronics, and smart-metering applications with the MLX90392 three-axis magnetic field sensor, which can operate from a 1.8 V power rail shared with other components such as logic devices. Requiring no dedicated LDO or regulator, the competitively priced MLX90392 simplifies design, trims bill-of-materials costs and saves PCB space. Measuring just ...

Vishay has created a complete proximity sensor inside a single surface-mount package – integrating laser (940nm VCSEL), photodiodes, amplifiers, ADC and DSP into 2 x 1.25 x 0.5mm. Called VCNL36825T, it can detect objects up to 200mm away through a hole as small as 1.6mm, and pulsed operation allows power to be reduced, to an average below 7μA at ~3 detections ...

Sensirion and Nicolay have teamed up to offer an evaluation kit that measures air flow and pressure for human ventilator development. The companies already have an evaluation kit for proximal measurements of inspiratory and expiratory respiratory gas flow rates – Sensirion makes the flow sensors and Nicolay the connector and cable. “Having received many inquiries from ventilator manufacturers about whether we ...

ST has created  three-axis linear accelerometer for “non-safety”, it said, automotive applications including anti-theft, telematics, infotainment, tilt measurement, inclination measurement and vehicle navigation. Called AIS2IH, it has user-selectable full-scales covering ±2, 4, 8 and 16g (survivable shock is 10,000g), and output data rates between 1.6Hz and 1.6kHz. There are five modes all-told, one nominally high-performance and four nominally low-power – which ...

Over 340 new products have been added to the PRO factory automation sensors range by RS Components. The range now includes ultrasonic proximity sensors and fibre optical sensors which join the photoelectric proximity sensors (through-beam, retro-reflective and diffuse), inductive proximity sensors and capacitive proximity sensors. The sensors are used to detect a range of materials including metals, plastics, paper, liquids, ...

Vesper of Massachusetts is claiming high fidelity for a MEMs piezo microphone that picks up the vibration of the user’s voice through the skull. Inside is the mems, an amplifier and a power regulator. Called VA1200, the company describes it as “the world’s first analogue piezoelectric voice accelerometer. Unlike a traditional microphone, the VA1200 is completely immune to ambient sounds, ...

Infineon is claiming a first: AEC-Q103 qualification for a MEMS microphone. It is the IM67D130A, which operates over -40°C to +105°C and has an acoustic overload point (AOP) of 130dB SPL which “allows the microphone to capture distortion-free audio signals in loud environments. Because of that, it can be placed inside or outside of the vehicle”, said the company. It “is ...
