Abstract: A parking space monitoring device that calculates a parking space with higher accuracy. The parking space monitoring device includes an obstacle detection unit (2, 3, 4) that uses a relative distance (Ri) and relative angle (?i) between an obstacle (Cp) near a vehicle (1) and the vehicle to detect a relative position (Pi(R1, ?i)) of the obstacle with respect to the vehicle, a memory (8) that stores the relative position (Pi) detected by the obstacle detection unit in association with movement information of the vehicle, and a parking space calculation unit (7) that calculates a parking space based on the relative information (Pi) and the movement information that are stored in the memory.

Abstract: A multi-color small amount painting system of the present invention stores small unit amounts of paint having a variety of paint colors and may selectively feed desired color paint to a painter of a painting robot or the like. The painting system stores the paint having a large number of paint colors in a stock unit in the form of paint cartridges. The paint cartridge of the paint color selected is picked up from the stock unit and carried by a carrier and is loaded on the painting robot or an automatic painting device. Subsequently, the paint within the paint cartridge loaded is fed to the painter of the painting robot or the automatic painting device by a paint feeding mechanism. In addition, the system ensure an advantage that the painting system is high in efficiency of painting work including the exchange of colors and is small in size as a whole.

Abstract: A moving object detecting device is arranged for detection in time series of an angle of respective received-wave signals at every moment with respect to basic axes in a vector plane, the basic axes being a pair of intermediate signals obtained by converting frequency deviation components of the received-wave signals responsive to incident on a wave receiver of reflected waves of radiated energy by a wave radiator from an object moving in a supervisory zone. Such moving object can be thereby detected at a high precision, irrespective of how quickly or slowly it moves within the zone.

Abstract: A composite type crime preventive sensor processes output detection signals from a plurality of sensor units of mutually different detection systems for ranking the signals into a plurality of grades depending on signal level, and provides an intruder detection signal when a sum of ranked level values is above a preset reference value, whereby any risk of alarm failing and erroneous alarming can be effectively minimized.
