  • Patent number: 5435573
    Abstract: A wireless remote control system is provided. The remote control system includes a remote unit and a receiver unit, and may be utilized in connection with a video game system or other controllable system. The receiver unit includes a plurality of detectors for detecting a signal transmitted by a remote unit. An angle-limiting device is coupled to each detector for limiting the signal which may be received by the particular detector to that signal which is transmitted from a particular location. In one embodiment, the angle-limiting device may limit the signal received by the detector to that signal transmitted from within a specified angular range relative to the detector. In a preferred embodiment, the angle-limiting devices coupled to the plurality of detectors may be arranged so that each angle-limiting device allows a signal to be received by the respective detector from a unique angular region. In another embodiment, the angular regions may be overlapping.
