  • Patent number: 8063591
    Abstract: The motor driving device includes a first function of supplying power to a motor so that the motor generates a driving force to drive a driven member, a second function of detecting a current flowing through the motor, a third function of performing a power supply control in order that a value of the current detected by the second function is maintained within a target range, a fourth function of performing a power supply operation in which the motor is supplied with power for a predetermined time period which is short enough to avoid the driven member from being driven by the motor, before the third function performs the power supply control, and a fifth function of making a judgment on a state of each of the first to third functions on the basis of the value of the current detected by the second function during the predetermined time period.

  • Patent number: 7906927
    Abstract: It is intended to realize a signal input method which makes it possible to add another method to an existing method later in a simple manner as well as an opening/closing controller which employs two methods and can be constructed by adding another method to an existing method in a simple manner. A signal processing circuit (5) is inserted in an auto signal path of a control circuit (1) which performs opening/closing control with a pinch preventing function on the basis of an auto signal (AUTO), a close signal (UP), and an open signal (DOWN) which are input via respective signal paths. The auto signal and a detection signal of an additional pinch sensor are input to the control circuit via the signal processing circuit in the form of serial signals.

  • Patent number: 7855525
    Abstract: An actuator includes a motor operated by a controller through a pulse width modulation drive signal applied to a drive circuit that drives the motor. The actuator has an output shaft connected to a coupling structure for manipulating a device such as a variable geometry turbine (VGT) or an exhaust gas recirculation (EGR) valve. The device has a range of motion limited by first and second mechanical stops located at opposing low and high ends of the range. The controller learns the location of the mechanical stops during calibration. An external control unit transmits a desired position to the actuator. A protocol allows the external control unit to implicitly request a positioning mode by virtue of what value range the desired position falls into. The controller is configured to limit the drive signal to a non-harmful level when one of the positioning modes calls for pushing the device against one of the stops.

  • Patent number: 7816879
    Abstract: The present invention is a system for high torque operation of a movable barrier utilizing a compact hub motor device, which may be directly coupled to a movable barrier without the use of additional gearing systems. The flat geometry provides high dynamic acceleration with short electrical and mechanical time constants, and its planetary gearing system implemented within the device allows for compact, more efficient access systems. Eliminating a gear system in accordance with the present invention lowers maintenance requirements, increases efficiency, and streamlines operation of movable barriers.

  • Patent number: 7804262
    Abstract: An electronic apparatus externally detects open protector contacts inside of a compressor. The compressor includes a compressor motor having a run winding and a start winding. The compressor motor also includes internal protector contacts that open the electrical circuit to the “C” terminal in a protection condition. A compressor running indicator circuit is electrically connected between the “S” and the “R” terminals to indicate a compressor running condition. Also, a protection indicator circuit is electrically connected between the “C” and the “S” terminals to indicate a voltage present across the “C” and the “S” terminals. The protection indicator circuit is also coupled to the compressor running indicator circuit such that the protection indicator circuit is disabled when the compressor is running normally and the protection indicator is enabled and indicates when protector contacts open inside of the compressor.

  • Patent number: 7764036
    Abstract: A controller for controlling a sliding roof sets, as an operating area, a predetermined range in the sunroof slidable range and controls a motor driving the sliding roof such that the sliding roof slides in the operating area. When the sliding roof stops near a sliding lock end, the stop position is stored on an assumption that the positional deviation would occur. The sliding roof slides again from the stop position. Based on whether a traveling distance from the stop position to the sliding roof comes into contact with the tilt lock end is longer than the sunroof slidable range, the positional deviation is determined. It is possible to accurately determine whether the sliding member is locked and stopped by positional deviation or the intrusion of foreign object.

  • Patent number: 7741801
    Abstract: The invention provides a device for automatically opening and closing a lid of a trash bin in noncontact fashion disposed in a lavatory unit of an aircraft. On the upper portion of a trash bin 100 disposed in a lavatory unit of an aircraft is attached a lid 50 that pivots via a shaft 250. The reflective infrared radiation sensor 200 attached to a lid frame 60 irradiates infrared radiation IR and detects an object. When the object is detected, a control means drives the DC motor 220 to pivot the shaft 250 via a rotating lever 240 and link arms 242 and 244 to open the lid 50 downward. The fully closed state and the fully opened state of the lid 50 can be detected by position detecting sensors 260 and 262.

  • Patent number: 7737653
    Abstract: A method of controlling a motorized window treatment provides for continued operation of the motorized window treatment during an overload condition, a low-line condition, or an electrostatic discharge (ESD) event. The motorized window treatment is driven by an electronic drive unit having a motor, a motor drive circuit, a rotational position sensor, a controller, and a memory for storing the command. The controller stores the present position of the motorized window treatment in the memory each time the rotational position of the motor changes by a predetermined angle, such that a plurality of positions are stored in the memory. When the controller is reset due to an overload condition or ESD event, the controller recalls the desired position from the memory, determines the present position, and continues to drive the motor drive circuit in response to the command and the present position.

  • Patent number: 7710057
    Abstract: A raindrop sensor outputs a measurement signal, which corresponds to a quantity of raindrops in a predetermined sensing range in a wiping range on a windshield. A prohibited time period setting arrangement sets a time period, during which a wiper blade is predicted to pass through the predetermined sensing range, as a raindrop quantity sensing prohibited time period based on an elapsed time from a time point of supplying a drive command signal to a wiper motor, which drives the wiper blade. The determining arrangement determines the quantity of raindrops on the windshield based on the measurement signal outputted from the raindrop sensor in a raindrop quantity sensing execution time period, which is outside of the raindrop quantity sensing prohibited time period.
