Abstract: Upon identifying an authorized user approaching a vehicle, vehicle locks are controlled to permit the authorized user to access an authorized area based on a user authorization. Permitted vehicle features within the authorized area for the authorized user are identified based on the user authorization. Upon receiving a user input selecting one permitted vehicle feature, the selected permitted vehicle feature is actuated based on determining that a state of charge of a battery is above a charge threshold. Upon determining that the state of charge of the battery decreases below the charge threshold, actuation of the selected permitted vehicle feature is stopped. Then an engine is controlled to charge the battery based on the user authorization.

Abstract: A computer includes a processor and a memory storing instructions executable by the processor to select a scanning rate for a first sensor of a vehicle based on at least one of data related to a current time or data related to a location of the vehicle; instruct the first sensor to run at the selected scanning rate; in response to receiving data from the first sensor indicating a newly present object, turn on a second sensor; and then record data from the second sensor. The second sensor has a higher power draw than the first sensor.

Abstract: A charge level of a sensor battery providing power to a sensor in a vehicle is determined. A charge depletion of the sensor battery is determined based on the charge level. A recharge rate to recharge the sensor battery is determined based on a time elapsed on a previously traveled path, a current charge level, and the charge depletion. Upon activation of the vehicle, one or both of a propulsion or a vehicle battery is actuated to recharge the sensor battery at the recharge rate.

Abstract: While a vehicle is in a minimal power state, a first sensor is activated based on a location of the vehicle within a monitored area. The vehicle is transitioned to an on state based on detecting an object via data from the first sensor. Then the vehicle is operated to block an exit from the monitored area based on identifying the object as an unauthorized object.

Abstract: System (10) is disclosed including an acoustic sensor array (20) coupled to processor (42). System (10) processes inputs from array (20) to extract a desired acoustic signal through the suppression of interfering signals. The extraction/suppression is performed by modifying the array (20) inputs in the frequency domain with weights selected to minimize variance of the resulting output signal while maintaining unity gain of signals received in the direction of the desired acoustic signal. System (10) may be utilized in hearing, cochlear implants, speech recognition, voice input devices, surveillance devices, hands-free telephony devices, remote telepresence or teleconferencing, wireless acoustic sensor arrays, and other applications.
