  • Patent number: 11513516
    Abstract: An autonomous running vehicle transmits a camera image around the vehicle photographed by a camera to a remote monitoring center. An obstacle is detected on the basis of information obtained from autonomous sensors including the camera. When an obstacle is detected, the autonomous running vehicle is automatically stopped. The remote monitoring center determines, when the autonomous running vehicle automatically stops, whether or not the run of the autonomous running vehicle is permitted to restart on the basis of the received camera video. When it is determined that the autonomous running vehicle can be restarted, a departure signal is transmitted to the autonomous running vehicle. When the departure signal is received from the remote monitoring center, the autonomous running vehicle restarts running.

  • Patent number: 10060527
    Abstract: During changing of a shift range (for example, from P-range to NotP-range), an SBW-ECU determines whether it is in a range-change delay condition (a switching completion time of the shift range is delayed than a normal switching completion time). When it is determined that it is in the range-change delay condition, it is determined whether a target range should be changed to a safer range (for example, P-range). As a result, when it is determined that the target range should be changed to the safer range, the target range is changed to the safer range. Thereby, even if a driver determines that the shift range cannot be changed before the switching completion of the shift range and the driver gets off the vehicle, the shift range can be changed to the safer range (P-range).

    Abstract: A variable frequency motor drive comprises a converter including a rectifier having an input for connection to an AC power source and converting the AC power to DC power. A DC bus is connected to the rectifier circuit. At least one bus capacitor is across the DC bus. An inverter receives DC power from the DC bus and converts the DC power to AC power to drive a motor. A controller is operatively connected to the converter. The controller comprises a speed control controlling the inverter responsive to a speed command to maintain a desired motor speed. A speed foldback control measures DC bus ripple voltage and regulates the speed command responsive to the measured DC bus ripple voltage.

  • Patent number: 9010549
    Abstract: An apparatus for raising and lowering a carrier for supporting clothes hangers or other hanging articles within a wardrobe closet that includes a tube, brackets for rotatable mounting of the tube, a tubular motor coupled to the tube for rotating the tube, and a base that attaches to a side panel of the wardrobe closet. Two arms each lie on a plane parallel to the base and to the side panel, attach at their ends to the carrier, and are mounted on the base so that they may oscillate and pivot in the plane between two positions, raising and lowering the carrier. At the lowest position the carrier releases from the arms and drop further. Fabric straps are wound onto and unwound from the tube to raise and lower the arms as the tube is rotated. A remote control receiver or programmable device may be used to control operation of the motor.

  • Patent number: 8973303
    Abstract: The invention relates to a control device (10) for use in an ambient light control system (20) for controlling ambient light entering a space (1) through an opening (2). An ambient light prediction unit (11) provides ambient light prediction values, which are predictions of an ambient light property at the opening (2). An ambient light adjusting unit (12) provides, at different ambient light adjusting time points, an ambient light adjusting signal depending on the ambient light prediction values for an upcoming ambient light prediction time period. The ambient light adjusting signal is adapted for use by an ambient light modifying element (22) for modifying the entering of ambient light into the space (1) through the opening (2). By taking the predicted ambient light conditions at the opening (2) into account, necessary adjustments can be made at temporally spaced ambient light adjusting time points, resulting in fewer disturbances of the users.

  • Patent number: 8952642
    Abstract: Temperature rise in semiconductor switching element that is part of a power conversion device is estimated to assess the degradation and remaining lifetime of the switching element. This is accomplished with a heat generation amount calculation unit in a calculation processor, where current command values Id* and Iq* and voltage command values vu*, vv* and vw* are used to calculate a chip loss. Current values iu*, iv* and iw* of all output phases are estimated from the current command values. The ON/OFF loss of the chip is represented by a function of an estimated value for a current flowing in each output phase, and the loss can be derived by integration with a PWM carrier frequency f. With respect to a conduction loss, a conduction time is integrated with the estimated current value and a saturation voltage, which is a function of the estimated current value.

    Abstract: A delay circuit for a fan includes a signal generation circuit, a first switch, a delay microchip, and a second switch. The signal generation circuit receives a driving signal and generates a control signal according to the driving signal. The first switch is electronically connected to the signal generation circuit to receive the control signal. The second switch is electronically connected between the delay microchip and the fan. When the signal generation circuit is electronically connected to the fan via the first switch, the control signal is transmitted to the fan to activate the fan. When the signal generation circuit is electronically connected to the delay microchip, the delay microchip receives the control signal and outputs a delayed control signal after a predetermined delay time, and the delayed control signal is transmitted to the fan via the second switch to activate the fan.

  • Patent number: 8941344
    Abstract: In at least one implementation, a vehicle wiper control system includes an actuator and a controller. The actuator is coupled to the wiper and operable to selectively move the wiper from a normal operating position engaged with a vehicle surface to be wiped and to a deployed position not engaged with said vehicle surface. The controller is communicated with the actuator and with a source of weather information regarding one or more weather factors, the controller being operable to cause the actuator to move the wiper from its normal position to its deployed position when one or more of the weather factors are at or beyond a threshold for said one or more weather factors. This may cause, for example, a wiper blade to be moved off of a vehicle surface if the current or predicted weather is indicative of possible snow fall or ice formation.
