Abstract: To provide a moving body detection system capable of reliably receiving response signals and discerning the arrangement of opposing moving bodies. A moving body detection system for transmitting and receiving signals in such a manner that moving bodies can detect each other, wherein each moving body transmits an ID code for identifying the moving body itself and giving a priority to the moving body as an ID code signal of a fixed time period, each moving body receives said ID code signals of other moving bodies, each moving body receiving an ID code signal makes a determination as to whether or not a neighboring upper order moving body of a higher order than itself is present within a prescribed distance and each moving body determining the presence of a neighboring upper order moving body receives a detection signal transmitted from a detection side moving body and transmits a response signal only when the neighboring upper order moving body is determined not to be present.

Abstract: A moving body detection system for detecting moving bodies by transmitting and receiving signals between the moving bodies. Each moving body transmits an ID code capable of identifying the moving body itself. A detection side moving body receives the ID code signal based on changes in driving conditions, discriminates the received ID signal, and transmits a detection signal with the ID code and the ID code of the detection side moving body itself added thereto. A non-detection side moving body receives the detection signal, and transmits a response signal with its own ID code and the ID code of the detection side moving body added if the ID code added to the detection signal is the same as its own ID code. Furthermore, the detection side moving body receives the response signal and measures the distance to the non-detection side moving body having the same ID code as the response signal.

Abstract: A moving body detection system for detecting moving bodies by transmitting and receiving signals between the moving bodies, each moving body transmits an ID code capable of identifying the moving body itself as a fixed output ID code signal for a fixed period. A detection side moving body receives the ID code signal for the same transmission period as the ID code signal based on changes in driving conditions, discriminates the received ID signal and gives an order of priority to each ID code based on the discrimination results, and transmits a detection signal with the ID code and the ID code of the detection side moving body itself added at prescribed time intervals in ID code order. A non-detection side moving body receives the detection signal, and transmits a response signal with its own ID code and the ID code of the detection side moving body added if the ID code added to the detection signal is the same as its own ID code.

Abstract: An inclination sensor is contemplated which includes case means having a cavity formed in the interior thereof, with this cavity having a longitudinal slope which is generally V-shaped in longitudinal profile, downwardly concave, and having a downwardly facing apex. A movable member is movable longitudinally along the slope within said cavity. A detecting means is operable to detect the inclination of a mounting body to which said case means is attached, in response to longitudinal movement of the movable member along the longitudinal generally V-shaped slope. A restricting means is provided by the apex and is operable to impede movement of the movable member out of the apex only until the case means undergoes a predetermined, longitudinal tilting movement.

Abstract: A flasher device flashes a selected one of a plurality of groups of indicator lamps selected by a flasher starting switch. An intermittent voltage is supplied to the selected group of indicator lamps to cause the lamps to flash. A capacitor is operatively connected to the selected group of indicator lamps and the rate of change of the voltage across the capacitor is indicative of the resistance of the selected group of indicator lamps. The frequency of the intermittent voltage supplied to the indicator lamps to flash the lamps is varied in response to the rate of change of the voltage across the capacitor. As the rate of change of voltage across the capacitor varies in relationship to the resistance of the selected group of indicator lamps, the change in the frequency of the intermittent voltage supplied the indicator lamps and thus the flash rate of the indicator lamps is representative of the resistance of the group of lamps.
