Abstract: A left object detection device for detecting an object left behind in a monitoring target area includes an acquisition section which acquires an image of the area from an image pickup device for picking up an image of the monitoring target area, a processing section, and an output section which outputs in accordance with a result of the processing section. Upon detection of the object which has been kept static for a given time period as an article from the image acquired by the acquisition section, the processing section starts a timer for counting time from detection of the article, determines whether or not a person who owned the article matches a person in the image acquired by the acquisition section, stops the timer upon determination that they match, and does not stop the timer upon determination that they do not match. The processing section determines whether or not the timer counts in excess of a predetermined time period.

Abstract: A schedule proposal system includes a data server for storing information collected at a plurality of stations and related to passengers and a computing server storing a program for predicting the numbers of passengers who wait for trains and a program for determining an increase or reduction in the number of trains to be operated. The computing server executes, at predetermined time intervals, the program for predicting the numbers of passengers who wait for trains and the program for determining an increase or reduction in the number of trains to be operated. The program for predicting the numbers of passengers who wait for trains predicts, based on the information related to passengers, the numbers of passengers who wait for trains at the plurality of stations in a predetermined time zone.

Abstract: In the state that a train moves from a track circuit 3T toward a track circuit 5T, and a train detection signal TD1 is supplied from the boundary between the track circuits 3T and 5T to the track circuits 3T and 5T, and the train detection signal TD1 is received by the train, if the signal intensity is suddenly reduced greatly immediately after the axle of the train passes the boundary between the track circuits 3T and 5T, it can be decided that the train passes the boundary between the track circuits 3T and 5T. Therefore, if absolute position information of the track circuit 5T is preserved beforehand in the train, the movement distance calculated from pulse output of a speed generator is corrected (replaced) in the absolute position information of the track circuit 5T, and hereafter is updated by the pulse output, thus the position of the own train can be easily detected as a movement distance.

Abstract: In an automatic train stop system in which a track circuit 3 is divided into track circuit sections 1T, 2T and 3T, and a digitized train control information telegram (ATS telegram) 8 is transmitted through the track circuit sections on carriers having different frequencies, a carrier sensor 12 mounted on a train 5 receives a carrier in the track circuit 3 and detects a track circuit boundary 31 by detecting a level change of the carrier, whereby an onboard system grasps the position thereof and controls the train 5 based on the information of the ATS telegram 8.
