Abstract: In system and methods for theft prevention or mitigation, driver-related data associated with one or more authorized drivers of an insured vehicle may be collected over time. The authorized drivers and the insured vehicle may be covered by an insurance policy issued by an insurance provider. Based upon the collected driver-related data, a database associated with the authorized drivers may be built. Current driver-related data associated with an individual currently driving, attempting to start, or sitting in a seat of the insured vehicle may be collected. It may be determined, using both the database and the current driver-related data, that the individual is not among the authorized drivers. A disablement of an operation of the insured vehicle may be caused, and/or the individual may be caused to be prevented from starting or otherwise operating the insured vehicle, to facilitate preventing or mitigating theft of the insured vehicle.

Abstract: Techniques are generally described for motion detection by supplying voltage pulses to a radio frequency (RF) circuit. In some examples, an RF motion detection circuit may output a first RF signal based at least in part on a first voltage pulse. In some further examples, the RF motion detection circuit may receive a second RF signal, the second RF signal being the first RF signal reflected from an environment external to the RF motion detection circuit. In some further examples, the first RF signal and the second RF signal may be mixed to generate a difference component signal. A first output voltage representing the difference component signal may be generated. In some examples, the first output voltage may be used to detect motion in the environment.

Abstract: In one embodiment, a system displays a priority sign for a first road and a yield sign for a second road as a default right of way for a road intersection. The system receives signals from one or more X2X sensors detecting a traffic flow for a predetermined segment of road for each of the first and the second roads before the road intersection. If it is determined the traffic flow of the first road has no vehicle and the traffic flow of the second road includes at least one vehicle, the system initiates a first timer to count a predetermined time duration. If the traffic flow of the first road is determined to remain with no vehicle for the predetermined time duration, the system reverses the default right of way for the intersection so traffic signs for the first road displays yield and the second road displays priority.
