streamCTX - Low-Latency Sensor Streaming and Control I/O for Physical Edge AI

streamCTX records analog and digital measurement data and streams it, timestamped, with extremely low latency to an external device. In the opposite direction, it receives commands to control its digital outputs. An API is available for telemetry.

Streaming to the Device of Your Choice

The external device can be a MEC4000 rail computer with Neural Network Accelerator, or another existing system. This gives you a direct data path from the sensors to AI-based analysis in the vehicle - the foundation for Physical Edge AI applications on rolling stock.
