Abstract: PROBLEM TO BE SOLVED: To provide a wiper controller for preventing an operation of wiper blades causing a feeling of incongruity at an intermittent stop by holding wiper arms so as not to move from a predetermined stop position when the wiper system is intermittently stopped or stored.SOLUTION: When an electric motor is in a stopping state to stop the wiper arms at target stopping positions when the wiper system is intermittently stopped or stored, a distance between the target stopping position and the present position of each of the wiper arms is recognized by using a relative position signal, and the electric motor is controlled on the basis of recognition to hold the wiper arms at the target stopping positions. In the stop position holding control, it is determined whether or not the wiper arms are positioned within a position holding allowable range, and if they are out of the position holding allowable range, a motor output is gradually increased each time the wiper arms are separated by one pulse of a relative position signal. After that, if the relative position signal has no change even after the lapse of a predetermined time, the output is further increased. Meanwhile, each time the wiper arms approach by one pulse of the relative position signal, the motor output is gradually increased.

IPC: H04W48/10
Filed: 2010-04-28
Abstract: PROBLEM TO BE SOLVED: To transmit video signals from a video signal transmission terminal to a video signal reception terminal so that the video signal reception terminal can display video at such timing as conforms to video display specification even if there exists radio LAN beacon which interferes with the communication between the video signal transmission terminal and the video signal reception terminal.SOLUTION: Upon detecting a beacon signal transmitted from other radio system, the detected beacon signal is analyzed to predict the period during which the beacon signal is transmitted(105). During the time period in which transmission of the beacon signal is predicted, transmission of video signal is stopped, and during that period, the video signal is accumulated in a buffer (102) in a transmission terminal. When that period has passed, the video signal accumulated in the buffer (102) is transmitted to a reception terminal (200) together with the video signal synchronization information by utilizing a blanking period as well.
