Not only are these sensor circuits prone to variations in their as-manufactured parameter values, there are also end-user manufacturing-induced variables that must be accommodated and reduced to ...

Over time, the performance of optical isolators or sensors can degrade. But a simple auto-calibration circuit will account for changes in LED and sensor characteristics to keep optical devices running ...

Aptiv has patented a technique for calibrating vehicle sensors by identifying triggers, generating calibration paths, and selecting the best path based on various factors. The vehicle travels along ...
