Abstract: A remote control system for controlling a television receiver or the like, which has an operating portion including a diaphragm and at least four light receiving elements. In the remote control system, light issued from an external light source is received by the light receiving elements through the diaphragm. Further, the direction in which the operating portion is oriented is detected on the basis of light receiving signals outputted, by corresponding single electrodes, from each of the light receiving elements. Furthermore, in a unit such as a to be controlled television receiver, a cursor is displayed at a position toward which the operating portion is turned on the screen of the unit. Then, the cursor is moved on the screen in response to change in the direction in which the operating portion is oriented. Subsequently, a desired operation is performed by depressing a switch of the operating portion when the cursor is superposed on an indication of the desired operation in a menu displayed on the screen. Thereby, the remote control system is easily manipulated.

Abstract: A volume amplitude limiting device includes a volume adjustment unit, an amplitude limiting unit, and a control unit. The volume adjustment unit adjusts the amplitude of an input sound signal to a larger degree as the adjustment value increases and outputs the resulting sound signal. The amplitude limiting unit limits the amplitude of the sound signal output from the volume adjustment unit to an output limitation value and outputs the resulting signal to a speaker. The control unit sets an adjustment value for the volume adjustment unit and also sets an output limitation value for the amplitude limiting unit according to an adjustment value.
