  • Patent number: 10259170
    Abstract: A method for use in efficiently joining together multiple workpieces to inhibit establishment of weld material in unwanted areas. The method uses a hybrid shaping-and-energizing system having a shaping tool and an ultrasonic horn. The method positions the hybrid shaping-and-energizing system proximate a workpiece, uses the shaping tool to form at least one recess in the proximate workpiece, and applies weld energy to the proximate workpiece using the ultrasonic horn. The recess is formed and the weld energy applied such that molten workpiece material becomes disposed within the recess, thereby inhibiting formation of weld material in the unwanted areas.

  • Patent number: 10260405
    Abstract: An internal combustion engine has a cylinder configured to combust an air-fuel mixture and expel an exhaust gas and a turbocharger for generating a pressurized airflow to the cylinder. The turbocharger includes a turbine scroll defining an inlet and an outlet, an exhaust gas driven rotating assembly having a turbine wheel disposed inside the turbine scroll, and a waste-gate defining an opening. A first sensor detects turbine outlet pressure. A second sensor detects turbine inlet temperature. A controller determines an effective area of the waste-gate opening and an exhaust gas mass flow-rate. The controller also determines a turbine inlet pressure in response to the detected turbine outlet pressure and the turbine inlet temperature, and the determined waste-gate opening effective area and the exhaust gas mass flow-rate. The controller additionally regulates a supply of fuel to the cylinder corresponding to the pressurized airflow affected by the determined turbine inlet pressure.

  • Patent number: 10259448
    Abstract: A hybrid vehicle propulsion includes an engine and a first electric machine, where each is configured to selectively provide torque to propel the vehicle. The propulsion system also includes a second electric machine coupled to the engine to provide torque to start the engine from an inactive state. A high-voltage power source is configured to power both of the first electric machine and the second electric machine over a high-voltage bus. The propulsion system further includes a controller programmed to deactivate the engine and propel the vehicle using the first electric machine in response to the vehicle being driven at a steady-state speed for a predetermined duration of time. The controller is also programmed to restart the engine using the second electric machine powered by the high-voltage power source.

  • Patent number: 10259451
    Abstract: Systems and methods are provided for mitigating motion sickness. When motion sickness is predicted, the motion sickness mitigation system alters vehicle performance, cabin conditions, and/or alerts the occupant to upcoming vehicle actions, to avoid or alleviate motion sickness. A controller includes a processor that receives an occupant profile and traffic information for an upcoming trip of the vehicle on a route. Using the occupant profile and the traffic information, the processor calculates whether the occupant will experience motion sickness when the vehicle travels on the route. A vehicle performance signal correlated to the calculation, is delivered by the processor to initiate motion sickness mitigation. The vehicle performance signal varies operation of a steering actuator, an acceleration actuator, and/or a brake actuator to implement the motion sickness mitigation.

    Abstract: A method of tracking an object includes establishing a track from a plurality of sequential Doppler radar frames f?1, f?2, f?3, etc. A location of a representative centroid of a cluster of data points is identified in a Doppler radar frame f. A radial velocity between a location of the track in the Doppler radar frame f?1 and the location of the representative centroid of the cluster in the Doppler radar frame f is calculated. An error between a Doppler velocity of the track in the Doppler radar frame f?1 and the calculated radial velocity is calculated. When the calculated error is less than a minimum error threshold, the representative centroid of the cluster in the Doppler radar frame f is associated with the track.
