  • Publication number: 20240343297
    Abstract: In one or more embodiments described herein, devices, systems, methods and/or apparatuses are described that can facilitate provision of a single motor torque request based on a driver assistance system pinion angle request. The motor torque request can be generated absent arbitration between two or more requests from two or more different controller components. A device can comprise a steering control system that generates a motor torque request based on a single request from a single first controller component.

  • Patent number: 11796464
    Abstract: A fuel quality sensor can include a pump with a suction side and a pressure side for pumping fuel along a fuel flow path between an underground reservoir and a nozzle of a fuel dispensing unit; a first transmitter disposed at the suction side of the pump on a first side of a bypass plenum in fluid communication with the fuel flow path, the first transmitter configured to transmit a first light signal at a first predetermined frequency in the bypass plenum; a receiver disposed at the suction side of the pump on a second side of the bypass plenum and configured to receive the first light signal; and a control unit electrically connected to the first transmitter and the receiver and configured to determine at least one parameter of the fuel present in the fuel flow path based on the received first light signal at the first predetermined frequency.

  • Patent number: 11679717
    Abstract: The present disclosure relates to a method for operating a haptic system, the haptic system comprising at least one actuator and at least one haptic control device adapted to control the at least one actuator and to provide haptic feedback to a user, the method comprising the steps of: obtaining, from a feedback computational model, modelled feedback data, obtaining, from a feedback estimator, estimated feedback data based on measurement data determined from measurement made on the haptic system, overlaying the modelled feedback data and the estimated feedback data to generate blended feedback data, and providing the blended feedback data to control the haptic feedback to the user.

  • Patent number: 5269275
    Abstract: A pulse width modulated controller for N.sub.2 O and enrichment fuel delivery includes a system control logic section which processes signals from sensors for throttle position, engine speed and a number of other user-selectable parameters and a driver section controls electrically operated injectors or solenoid valves. The driver section allows the injectors to open only when all of the parameters sensed in the control section are met. Moreover, the driver section activates injectors according to a pulse generated by a pulse width modulation section which determines how long the injectors will remain activated. The pulse width modulation section receives signals based on the present throttle position and engine speed and adjusts these values according to values for N.sub.2 O and enrichment fuel based on engine speed and throttle position set by the user in a tuning section and thereby continuously provides the driver section with a pulse having a width proportional to the proper amount of N.sub.
