  • Patent number: 8217611
    Abstract: An automated refrigerator opener is described. The automated refrigerator opener includes a door seal separator (e.g., solenoid) for breaking a door seal between a refrigerator door and a refrigerator door casing. Also included is a powered door opener (e.g., linear actuator) for attaching with a refrigerator door and automatically opening the refrigerator door after the door seal is broken. A control device is communicatively connected with both the door seal separator and the powered door opener. The control device is operable for receiving an actuation command from a user and, thereafter, activates the door seal separator to break the door seal and cause the powered door opener to open the refrigerator door. Alternatively, if the door is already open, the control device is operable for causing the powered door opener to pull the door closed.

The interface system includes a relay system that does not interrupt, read, signal, or otherwise interfere with the communication lines between a body control unit, door control unit, or remote control transmitter or receiver. Thus, the interface system functions without the need to receive and transmit signals on the vehicle's communication bus.

  • Patent number: 7906926
    Abstract: A door drive control apparatus capable of an accurate detection, without misidentifying an inverse overrun condition, and a door drive control method that improves safety. The door drive control apparatus includes a power converter that supplies power to a door drive linear motor, and operates the power converter by feedback control using a speed detection value and a speed command value of the door, and controls a speed of the door. The door drive control apparatus includes a speed trouble determiner, which outputs a door inverse direction speed trouble signal in the event that the speed command value of the door exceeds either a positive or negative first setting speed, and the speed detection value exceeds a second setting speed of a polarity opposite to that of the speed command value.

  • Publication number: 20110060452
    Abstract: A conveyor system having a conveyor path and friction drive spaced along the path to drive carriers along the path. Each friction drive is controlled by a drive controller, which communicates tracking, routing, and other information directly to other drive controllers within range via a wireless signal. The drive controllers may also directly communicate wirelessly with a central controller. If the central controller or a desired destination drive controller is out of range of a particular drive controller, that drive controller may communicate through other drive controllers until the desired destination drive controller is reached, or a drive controller that is within range of the central controller is reached.

  • Patent number: 7889462
    Abstract: At least one embodiment of the invention relates to a protective circuit for protection of an appliance, in particular of an electric motor, against thermal overloading. In at least one embodiment, the protective circuit includes a first and a second terminal for connecting a temperature detection element; a detection unit for detecting whether a resistance value of the temperature detector element which is connected between the first and the second terminals, is in a first or a second resistance range; a short-circuit detector for identifying whether there is a short circuit between the first and the second terminals; signaling outputs for emitting signal messages to an evaluation unit when the detected resistance value is in the second resistance range and/or when a short circuit has been identified by the short-circuit detector; and a third terminal, which is connected to the second terminal via a predetermined resistance.

  • Patent number: 7877209
    Abstract: Rooftop cargo racks, otherwise simply known as roof-racks, provide an option for transporting cargo that does not use space inside a vehicle. However, despite the usefulness of roof-racks, once cargo is secured to a roof-rack on a vehicle there is the added potential for a collision between the cargo and some overhead obstruction—such as, for example only, a garage door, over-hanging sign, public parking structures, and tree branch. Previous collision avoidance systems that employ either ultrasonic acoustic or Doppler-based radar systems are poorly suited for detecting the potential of a collision between rooftop mounted cargo and an overhead obstruction. By contrast, aspects of the present invention provide systems and methods for reducing the risk of a collision between rooftop mounted cargo and overhead obstructions by providing a more suitable radar-based means for detecting overhead obstructions and warning drivers and, if present, passengers in vehicles when there is a risk of a collision.

  • Publication number: 20110006716
    Abstract: A method for protecting an electronic apparatus driven by a DC motor and a detection circuit for detecting positioning signals thereof. The electronic device includes an optical encoder, a code strip, and a DC motor. While moves along the code strip, the optical encoder outputs a first positioning signal and a second positioning signal for the control of the DC motor. The method includes the steps described below. First, states of the first and second positioning signals are detected. If the states of the first and second positioning signals are normal, the DC motor is controlled according to the first and second positioning signals. If the first positioning signal or the second positioning signal is abnormal, a preventive method is performed.

  • Patent number: 7834570
    Abstract: A method for operating an actuating element (30) comprises the following method steps: controlling the rotational frequency of an electric motor (1) to a constant value, calculating an estimate (FE) for the actuating force (F) acting on the actuating element, comparing the estimate (FE) with a predetermined limiting value, and detecting a current position of the actuating element (30) for the predetermined limiting value and assigning the detected position to a final position stored in a travel model. An actuating drive under the control of force and operating according to this method is low in noise and energy-efficient and can therefore be used, in particular, even to operate a battery-fed radiator valve driven in a wireless fashion.

  • Patent number: 7825617
    Abstract: A drive for a movable furniture part includes a motor to power the movable furniture part and a control or regulation unit to control or regulate the motor. The control or regulation unit is designed such that it has a threshold value which, if surpassed, causes the actuation of the movable furniture part by the motor. A measurement device is provided to capture the position of the movable furniture part, and the control or regulation unit is designed in such a way that the threshold value varies for at least two different positions of the movable furniture part.

  • Patent number: 7825618
    Abstract: A vehicle-mounted display device comprises a display mounted to a shaft, and operable to revolve with the rotation of the shaft; a transmission mechanism for coupling an output shaft of a motor with the shaft; a control module for controlling the motor; a baffle plate located at any position that enables it to rotate in synchronism with the rotation of the display, and a detection module for detecting the baffle plate. During the rotation of the display, when the detecting module does not detect the baffle plate in a predetermined period of time, the control module causes the motor to stop running or to turn in a reverse direction. This vehicle-mounted display device not only is reliably operable and electronically controllable, but also has anti-clamping and self-protection functions and has a simple structure and low cost.

  • Patent number: 7816878
    Abstract: A system and method for coordinating movement of a powered sliding door module and an access ramp for a vehicle. A system control board communicates with a current detector that can detect current on the power wires for the sliding door's motor. The current detector signals the system control board when it detects current and the system control board determines whether the ramp is stowed or deployed. If the ramp is deployed, the system control board stops and reverses the door so that the door remains open. The system control board then stows the ramp and closes the door. If the ramp is stowed, the system control board waits for the current in the door motor to return to zero and then determines if the door is completely open. If the door is not completely open the system control board does nothing. If the door is completely open, the system control board deploys the ramp.
