Abstract
An inductive system for vehicle information capture, having a radar module adapted to identify an echo signal having an amplitude over a threshold value, an interrogator module coupled to the radar module and adapted to initiate a radio frequency identification (RFID) information exchange when the amplitude is over the threshold value, a processor coupled to the radar module and the interrogator module, and a memory storage unit adapted to store RFID information. Examples disclosed herein provide methods and apparatus for vehicle sensors and vehicle identification.
Claims20
A vehicle sensor system, comprising:
- a radar module;
- and
- an inductive sensor module having a decode module to extract content from a sensor signal.
A traffic infrastructure element, comprising:
- a reflectarray having a reflection distribution for incident electromagnetic signals to reflect at a first gain value;
- and
- a radio frequency identification (RFID) tag module responsive to RFID transmissions from a reader device, wherein the RFID transmission activates the RFID module to return data to the reader device.
