Electromechanical Actuator

Thomson Industries, Radford, VA, has launched a compact electromechanical actuator that retains all of the intelligence built into its larger counterparts. Factory automation applications can benefit from the compact Electrak® MD actuator with up to 2 kN of force, advanced onboard electronics, andJ1939 CAN Bus support. Onboard intelligence enhances overall performance and eliminates space consumption by keeping any external equipment like encoders and switches within the actuator housing. It features feedback on position, J1939 CAN bus communication, low-current switching (PLC compatibility), and end-of-stroke indication output.

Renesas, Tokyo, Japan, has released a series of microprocessors (MPUs) that feature a dynamically reconfigurable processor (DRP-AI), the company’s vision-optimized artificial intelligence (AI) accelerator. The first product in the RZ/V series, the RZ/V2M, is designed to deliver a combination of real-time AI inference and excellent power efficiency in embedded devices. The RZ/V2M realizes power consumption as low as 4W (typical), which eliminates the need for heat sinks and cooling fans, greatly simplifying heat dissipation measures. The MPU features an imaging signal processor (ISP) capable of processing high-resolution 4K pixels at 30 frames per second.

Sleep Tracking Sensor

A sleep tracking sensor from TE Connectivity, Anaheim, CA, monitors vital signs including respiratory rate, heart rate, and other parameters like body motion and bed exit. It requires no external power or bias voltage and enables continuous monitoring without disturbing the user. The sensor is manufactured with PVDF film, and when placed onto a mattress, it monitors vital signs and provides comprehensive sleep data for more precise sleep quality analysis. The noncontact sleep sensor can be combined with a bedside sleep monitor, smartphone, and Web-based app to help track and better understand sleep patterns and create personalized feedback and suggestions to help improve sleep.

Temperature Sensors

A new line of miniature bearing embedment temperature sensors is available from Minco, Minneapolis, MN. The S7 and TC7 sensors commonly monitor the metal temperature of bearings in rotating equipment — the most reliable indicator of bearing condition — to give early warning of oil film breakdown before costly failures occur. Moreover, the sensor leads can be configured with either stainless steel feedthrough tubes or elastomer filled cables to block oil from wicking out of the machine housing along the lead wires.
