  • Patent number: 11028634
    Abstract: A manipulation detecting device for a vehicle includes a sensor electrode that is configured to have a capacitance that increases as a detection target approaches the sensor electrode and circuitry that is configured to selectively open and close an opening-closing body of a vehicle by controlling an actuator. A first determination value is used to determine proximity of the detection target to the sensor electrode. The circuitry is configured to selectively open and close the opening-closing body when the opening-closing body is in a stopped state and the capacitance of the sensor electrode is greater than or equal to the first proximity determination value and smaller than a second proximity determination value, which is greater than the first proximity determination value.

  • Patent number: 8328250
    Abstract: A door handle for a door of an automotive vehicle having a first gasket attached at a distal end of the door handle and a second gasket attached at a proximate end of the door handle. The first gasket and second gasket have an inner surface facing the outer surface of the door and an outer surface facing the respective ends of the door handle. The first gasket and the second gasket also include a lip formed of a resilient material, which protrudes outwardly relative to the outer surface of gaskets and extends longitudinally along the edge of the gaskets to sealingly engage the ends of the door handle. The lip is embossed so that it is recessed relative to the inner surface of the gasket to accommodate compression of the lip as the handle is displaced towards the door. A flattened portion extends from an end of the lip on the first gasket to dampen noise due to impact between the distal end of the door handle and an outer surface of the door.

  • Patent number: 7492508
    Abstract: A fiber amplifier includes at least one coreless end used for the input or extraction of optical energy. The coreless end has a transverse cross section which differs from the transverse cross section of the core at fiber locations remote from the end, so that the diameter of the input or extracted optical beam at the coreless end can be larger than the diameter of the fiber core, to increase an optical damage threshold of the fiber amplifier.

  • Patent number: 6508102
    Abstract: An improved estimator is provided for road/tire friction. The friction estimator provides near-real-time friction estimation, even while the car is accelerating, braking or turning. It is desirable to have an instantaneous and continuous estimate of the road/tire friction, but an estimate that occurs over several wheel rotations is more realistic. The estimate relies on easily measured signals such as yaw rate, lateral acceleration, wheel speed, etc. The estimate can be used to give the driver or a closed-loop controller an advanced warning when the tire force limit is being approached.

  • Patent number: 5936820
    Abstract: An overheating protection system for a switching module prevents thermal breakdown of switching devices for passing currents through a load, for example an electric motor, while making it possible for the switching module to provide as much required current to the load as possible. The system comprises a temperature detector for detecting the temperature of a switching module, a temperature estimator for calculating a temperature change rate of a switching device inside the switching module corresponding to a current passed through the load and calculating an estimated value of the internal temperature of the switching module on the basis of the calculated temperature change rate and the detected temperature and a current limiter for on the basis of the estimated value correcting a target current value of a current controller controlling a current passed by the switching device.
