    • PROBLEM TO BE SOLVED: To provide a method for determining a position and an operation to detect the position of an object to be detected and exactly determine the operation of the object to be detected with high accuracy.SOLUTION: In the method for determining a position and an operation to determine the position and the operation of the object to be detected based on an infrared detection signal output from an infrared detection part receiving infrared ray emitted from the object to be detected, the infrared detection part includes at least two infrared sensor parts provided with a view angle limiting body to determine the operation of the object to be detected based on a position signal of the object to be detected that indicates a difference or a ratio of intensity of the infrared rays obtained from the two infrared sensor parts, and a signal obtained by differentiating the difference or the ratio with respect to time using the difference or the ratio of the intensity of the infrared rays as a function of the time.
    • 要解决的问题:提供一种用于确定检测待检测物体的位置的位置和操作的方法,并且精确地确定待检测物体的操作。 解决方案:在用于确定位置和操作的方法中,基于从接收从被检测物体发出的红外线的红外线检测部分输出的红外线检测信号来确定待检测物体的位置和操作 红外线检测部分包括至少两个设置有视角限制体的红外线传感器部分,以根据被检测物体的位置信号来确定被检测物体的操作,该位置信号指示被检测物体的差异或强度比 从两个红外线传感器部分获得的红外线,以及通过使用红外线的强度或红外线的强度的比率作为时间的函数来区分差异或相对于时间的比率而获得的信号。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a road-vehicle communication system for providing high-precision vehicle position information by suppressing a decrease in location accuracy when locating a vehicle with an uplink region as a plurality of split regions. SOLUTION: The road-vehicle communication system 1 includes: a plurality of photodiodes 9 provided at a beacon head 8 corresponding to the plurality of split regions constituting the uplink region; a determination part 50 determining whether light reception is permitted in each of the plurality of photodiodes 9; and a locating part 51 locating the transmission position of uplink light UO of an in-vehicle machine 2 on the basis of the determination result of the determination part 50. The road-vehicle communication system further includes a control part 49 causing the beacon head 8 to transmit downlink light DO including information about the transmission position when the determination part 50 determines that the light reception is permitted in only one photodiode 9 or only two photodiodes 9 adjacent to each other from among the plurality of photodiodes 9.
