Abstract
A digital license plate system having various power and communication modes to improve performance and increase expected battery life is disclosed. In one embodiment, a response to a sensor triggered plate event requires determination of whether a vehicle is running, parked or in-motion. This determination involves waking the processor, establishing wireless connectivity, and determining if the vehicle is in motion based on local sensor data.
