  • System and method for key absence management in a vehicle
    Patent number: 12257978
    Abstract: A system for key absence management in a vehicle configured to be started by an electronic key fob includes a key absence management controller that implements a method configured to authorize starting of the vehicle by monitoring presence and absence of the electronic key fob in the vehicle. If the controller finds the electronic key fob to be present in the vehicle, then the controller authorizes starting of the vehicle. If the controller finds the electronic key fob to be absent from the vehicle, then the controller authorizes starting of the vehicle based on detection of a keyless authority indicator. A vehicle configured to be started by an electronic key fob includes the system with the controller that implements the method.

  • AUDIO FILTER SYSTEM
    Publication number: 20250095625
    Abstract: A computer-implemented method executed by data processing hardware causes the data processing hardware to perform operations that include receiving multiple audio signals from a sensor array. The multiple audio signals include a target audio signal and interference audio signals. The data processing hardware then identifies a design constraint based on the multiple audio signals. The desired constraint includes a pass constraint corresponding to the target audio signal and a null constraint corresponding to the interference audio signals. The data processing hardware then compares a design filter weight of the design constraint with a filter weight maximum, designs an audio filter using the desired constraint, and filters the multiple audio signals using the designed audio filter.
