The motor control unit includes a motor control section for applying drive pulses to the pulse motor, a counting section for counting the number of drive pulses applied to the pulse motor, a voltage-drop detecting section for detecting a voltage drop of a drive power supply for the motor control section, and a writing section for writing a count from the counting section in a nonvolatile memory if the voltage-drop detecting section detects the voltage drop. | 09-17-2009 |
20090294711 | CONTROL ALGORITHM FOR FREEING AN EGR VALVE FROM CONTAMINATION ADHESION - A method of controlling a device having restricted movement. A controller is provided for controlling the operation of the device using a control algorithm. A normal operation control method is programmed onto the controller and is selectively activated by the controller to generate a normal control signal. A forcing control method is also programmed into the controller and selectively activates a forcing control signal. The normal operation control signal provides regular operation of the device, while the forcing control signal causes the device to operate in a manner that will correct the operation of the device when a restricted motion of the device is detected. | 12-03-2009 |
20100327198 | CONTROL DEVICE FOR PLUMBING APPLIANCES - The application relates to a control device comprising a control element that can be rotated on a first functional level, an electronic controller, an electric power supply, and a base for mounting the control device. Said control device is designed to control plumbing appliances comprising a water discharge point and an electronically controlled mixing valve that has a cold water connection and a hot water connection. The flow or the temperature of the water discharged from the water discharge point can be changed by rotating the control element. The control device according to the invention is characterized in that a second functional level can be assigned to the control element by means of an electronic or electric pulse. Said second functional level is mechanically identical to the first functional level. The temperature of the water discharged from the water discharge point can be changed by rotating the control element when the second functional level has been assigned. | 12-30-2010 |
20110024654 | ELECTRO-HYDRAULIC PROPORTIONAL FLOW VALVE SPEED REGULATING CONTROL SYSTEM AND ITS METHOD - An electro-hydraulic proportional flow valve speed regulating control system includes a PWM regulating device, an electro-hydraulic proportional flow valve, a hydraulic executing element, a speed measuring module, an electro-hydraulic proportional flow valve characteristic measuring module, and a feedforward control module. The speed measuring module measures a speed of the hydraulic executing element and sends the measured result to the electro-hydraulic proportional flow valve characteristic measuring module which measures a minimum actuating current and a maximum actuating current of the electro-hydraulic proportional flow valve and a maximum speed of the hydraulic executing element and inputs these measured results to the feedforward control module. With these measured results, the feedforward control module establishes a corresponding relationship between the speed of the hydraulic executing element and the valve core current and inputs the valve core current in correspondence with the setting speed value to the PWM regulating device, thereby driving the electro-hydraulic proportional flow valve. | 02-03-2011 |
