Abstract: A bicycle display unit is provided for displaying information to the rider. The bicycle display unit is preferably part of a bicycle computer that is battery operated. The bicycle display unit has a display panel with a front display surface and a backlight arranged to illuminate the front display surface for viewing the information displayed thereon. The battery is electrically coupled to the backlight to supply electrical energy thereto. The bicycle display unit also has a backlight switch command operatively coupled between the backlight and the battery to selectively turn the backlight “on” and “off”, and a control unit that extends the life of the battery by controlling the illumination of the backlight. The backlight switch command turns “on” the backlight upon receiving a predetermined operational command. The predetermined operational command can be a pre-selected time period, a shifting operation, a mode change, etc.

Abstract: A first orientation control system controls the orientation of the main body of a satellite so that the main body is oriented toward the center of the Earth, and a second orientation control system controls the orientation of an antenna so that the antenna is continuously directed toward a target (e.g., a satellite revolving around the Earth). Between these two control systems, there is inevitably mutual interference, due to dynamic effects. To prevent this mutual interference, the first control system controls the orientation of the main body of the satellite on the basis of antenna driving information of the second orientation control system, while the second control system corrects the antenna driving information on the basis of orientation error information of the first control system.
