  • Patent number: 10229364
    Abstract: In certain example embodiments, moisture sensors, defoggers, etc., and/or related methods, are provided. More particularly, certain example embodiments relate to moisture sensors and/or defoggers that may be used in various applications such as, for example, refrigerator/freezer merchandisers, vehicle windows, building windows, etc. When condensation or moisture is detected, an appropriate action may be taken (e.g., actuating windshield wipers, turning on a defroster, triggering the heating of a merchandiser door or window, etc.). Bayesian approaches optionally may be implemented in certain example embodiments in an attempt to improve moisture detection accuracy. For instance, models of various types of disturbances may be developed and, based on live data and a priori information known about the model, a probability of the model being accurate is calculated. If a threshold value is met, the model may be considered a match and, optionally, a corresponding appropriate action may be taken.

  • Patent number: 9667182
    Abstract: The invention describes a method for controlling a sensorless, brushless DC motor that is controlled via a bridge circuit preferably using pulse width modulation (PWM) having precommutation. According to the invention, in the braking operation each commutation interval is divided into two phases. A drive phase, lasting from the start of the commutation interval up to zero crossing in which the motor is controlled with the normal PWM, and a braking phase, lasting from zero crossing up to the next commutation time in which at least two motor phases are short-circuited and/or in which the PWM is operated with recovered energy. The efficiency of the control circuit is as low as possible so as to ensure that the braking energy is consumed in the control circuit.

  • Patent number: 7622878
    Abstract: A wiper unit controller for performing wiping at an accurate intermittent wipe cycle. The controller stores a maximum resistance value of a variable resistor having a resistance value that varies in accordance with the intermittent wipe cycle. When a reference time elapses after calculating a resistance value that exceeds the stored maximum resistance value, a computer renews the maximum resistance value with a new maximum resistance value.

  • Patent number: 7586275
    Abstract: A wiper device includes a sensor magnet fitted to an output shaft so that when wiper arms are positioned at upper reversal positions B relative to an origin position O, both hall ICs are opposed to an S-pole and when the wiper arms are positioned at lower reversal positions A relative to the origin point O, at least one of the hall ICs is opposed to an N-pole. When the wiper arms are abnormally stopped, the sensor magnet determines at the time of re-starting whether the wiper arms are positioned at the lower reversal positions A or at the upper reversal positions B relative to the origin position O and always starts the wiper arms toward the origin position O, whereby the positions of the wiper arms can be accurately detected by two hall ICs. After re-setting position data by re-starting the wiper arms toward the origin position O, the sensor magnet performs a normal control.

  • Patent number: 7528500
    Abstract: Disclosed herein is an intelligent wiper control system for a vehicle. A rain sensor unit controls the speed of wipers based on the amount of rain. An electronic control unit analyzes the input signal of the input unit. An output unit controls the output integrated circuits, and adjusts and controls the driving of the wiper motor. The input unit includes a remote key for inputting a signal for controlling the driving of a wiper system and wirelessly transmitting the signal. An output unit causes an emergency light to blink when the drive power of the wiper motor is set to firm power and the driver turns off an ignition key and then gets out of the vehicle while wipers are turned on.

  • Patent number: 7504798
    Abstract: A controller for controlling a wiper unit including a wiper and an intermittent wipe cycle setting device for setting an intermittent wipe cycle of the wiper. The cycle setting device is set at a plurality of positions respectively corresponding to different intermittent wipe cycles. Further, the cycle setting device has a resistance value, which changes in accordance with each of the positions, and generates an output signal, which is in accordance with the change in the resistance value. The controller computes position information of the intermittent wipe cycle setting device from the output signal by using a learned value. The computer adjusts the learned value in accordance with the computation result of the position information to correct the position information. Accordingly, resistance value variances of the intermittent wipe cycle setting device are automatically corrected.

  • Patent number: 7466097
    Abstract: A wiper control method and a wiper control device are provided which can smoothly respond to rapid change of a rainfall situation at passage of a rainfall shutoff environment such as a tunnel. A wiping state control part 42 determines entry of a vehicle into the rainfall shutoff environment, sets a wiping level low for the low level of rainfall less than a predetermined rainfall level in response to this determination or sets the wiping level high for the high level rainfall at the predetermined rainfall level or more. A rainfall level generation part 32 detects adhesion of raindrops and determines the rainfall level. A wiper driving signal generation part 48 determines wiper operation based on the rainfall level determined by the rainfall level generation part 32 and the wiping level set by the wiping state control part 42.
