| 318443000 | PERIODIC, REPETITIOUS OR SUCCESSIVE OPERATIONS CONTROL OF MOTOR, INCLUDING "JOG" AND "INCH" CONTROL | 6 |
| 20080303466 | FAN SYSTEM CONTAINING FAN CONTROL APPARATUS AND FAN CONTROL METHOD - A fan system includes a fan attached to a housing; and a DC motor configured to drive the fan. A fan control apparatus includes a control unit configured to control a rotation speed of the fan so as to periodically change around a specific rotation speed based on data corresponding to a specific rotation speed. | 12-11-2008 |
| 20090096400 | Starter Relay Control - A starter control system includes a power source, a starter motor, a starter relay, a control module, and an ignition switch. The starter motor is in operative communication with the power source. The starter relay is operatively interposed between the power source and the starter motor, and includes a high side node and a low side node. The starter relay is controllable to selectively enable power delivery from the power source to the starter motor responsive to activation of the high side node and the low side node. The control module includes a high side driver in operative communication with the high side node of the starter relay and a low side driver in operative communication with the low side node of the starter relay. The ignition switch is in operative communication with the high side node of the starter relay and in operative communication with the control module. | 04-16-2009 |
| 20130127389 | METHOD FOR THE ACTIVATION OF A WINDSCREEN WIPER MOTOR - A method for the activation of a windscreen wiper motor is disclosed, in which the motor is connected to a wiper blade by a drive shaft, which moves the wiper blade between two reversal points of a wiping field in differing movement direction, where the rotation speed and direction of the motor, or the speed of the wiper blade, is detected by a sensor device and is supplied to a control device as an input value. The motor, before reaching the respective reversal point, is switched off, whereupon the drive shaft continues to rotate further by a castor angle up to a standstill, and the wiper blade moves further by a trailing distance. The actual speed of the wiper blade is compared at the switch-off time with a nominal speed, and the motor is operated further for a period of time when the comparison results in a difference in values. | 05-23-2013 |
| 20130175961 | ELECTRIC POWER TOOL - An electric power tool is configured to control power supply to a motor based on an operational amount of the variable speed switch, and further configured to perform in an intermittent control mode in which power supply to the motor is varied intermittently in the same manner as if an ON operation and an OFF operation of the variable speed switch were repeated. It is also able to perform in a continuous control mode in which power supply to the motor is varied based on the operational amount of the variable speed switch. | 07-11-2013 |
| 20150297824 | SYSTEM AND METHOD TO DISTRIBUTE POWER TO BOTH AN INERTIAL DEVICE AND A VOLTAGE SENSITIVE DEVICE FROM A SINGLE CURRENT LIMITED POWER SOURCE - A system may regulate voltage supplied from a power source to an integrated circuit and/or an inertial device. A minimal voltage may be maintained in the integrated circuit by temporarily cutting off current to the inertial device to supply surges of voltage to the controller. Optionally voltage may be smoothed between said surges for example by adding capacitance and/or a current restrictor. | 10-22-2015 |
| 20160118864 | WIPER CONTROL APPARATUS OF VEHICLE - A wiper control apparatus includes a wiper motor for operating a wiper, and providing a ground terminal, a low-speed terminal, and a high-speed terminal. A cam plate is disposed inside the wiper motor and generates a control signal for stopping the wiper when an operation mode of the wiper is a stop mode. A controller is configured to selectively supply a power to a low-speed terminal and a high-speed terminal of the wiper motor by turning on/off of a low-speed relay and a high-speed relay according to an operation mode of the wiper, to selectively turn off the low-speed relay and the high-speed relay by using the control signal according to a rotation of the cam plate, and to decelerate a wiper speed when the wiper stops. | 04-28-2016 |
