Face recognition and liveness detection solution based on NXP EdgeReady MCU

NXP's EdgeReady MCU-based facial recognition solution leverages the i.MX RT106F crossover MCU to enable developers to quickly and easily add facial recognition with liveness detection capabilities to their products. Liveness detection prevents photo spoofing and is enabled by low-cost IR and RGB cameras. The solution’s development kit, SLN-VIZNLC-IOT, comes with fully integrated, turnkey software for rapid out-of-the-box operation, minimizing time to market, risk and development effort. Facial recognition is done entirely at the edge, solving many consumer privacy concerns. The NXP EdgeReady solution is part of the EdgeVerse™ edge computing platform.

Homemade 10KV electronic load

Commercial electronic loads are more expensive, especially high-power loads such as computer power supplies that must handle transient current spikes well above their nominal ratings (1800W spike for a 600W GPU) and should be tested under worst-case conditions to Ensure stability.

NetSoM: Lowering the Barrier to Entry for Ethernet, Wi-Fi, 2G, 3G, Audio, Video and IoT Applications

NetSoM is a family of open source, OpenWrt-powered system-on-module (SoM) kernels and the development boards that host them. Combined with our sample code base, these boards allow developers to go from scratch to mass production in record time. With support for Wi-Fi connectivity and two Ethernet phy ICs, it is soldered to a development board with two RJ-45 Ethernet ports. NetSoM is currently in production as an industrial LoRaWAN gateway solution, but it is widely applicable in areas as diverse as home automation, automotive networking, audiovisual data processing, and smart cities. As part of this project, we are releasing software for a variety of useful NetSoM applications. Among them are: an audio streaming (SIP telephony) application using the WM8960 codec, a video streaming (RTSP/MPEGTS) application using the OV5640 camera module, an Alexa-style speech recognition application, a UDP to CAN forwarding application, a LoRaWAN Gateway Application
