Abstract: A system and method is disclosed for communicating data and transmitting information between roadside infrastructure units regarding vehicle data, in some embodiments, the roadside infrastructure units have one or more communication nodes equipped with a wireless transceiver configured to communicate wirelessly with a vehicle such as a dedicated short-range communication (DSRC) or cellular system. Each communication node can also wirelessly communicate with one or more of the other remaining communication nodes in, for example, a mesh network. One of the communication nodes can establish a connection with the vehicle via DSRC, obtain vehicle-specific data, and transmit at least a portion of this vehicle-specific data to one or more other communication nodes in other roadside infrastructure units. The roadside units can change operation state (e.g.

The roadside units can change operation state (e.g., illuminate) in response to receive the vehicle-specific data indicating the vehicle approaching that roadside unit.

Abstract: A device for testing a power supply. The device includes a modulation generator, and a connection between the modulation generator and the power supply under test through which a load is injected to the power supply under test. A resistive load generator applies a resistive load to the power supply. A reactive load generator applies a reactive load to the power supply. A load selector selectively applies the resistive load and/or the reactive load to the power supply to be tested. The device further includes a discharge network that automatically or manually discharges capacitors of the device.

Abstract: An unmanned vehicle interface device includes a wireless transceiver configured with a radiation pattern that covers a particular spatial region, and a controller coupled to the wireless transceiver. The controller is programmed to detect an unmanned vehicle within the particular spatial region using the wireless transceiver, upon detecting the unmanned vehicle, communicate with the unmanned vehicle using the wireless transceiver to override existing controls of the unmanned vehicle, and after overriding the existing controls, forcibly control the unmanned vehicle.
