Title:
SENSOR BOARD FOR DETECTING START OPERATION, AND START OPERATION-JUDGING APPARATUS
Document Type and Number:
Japanese Patent JP3914030
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make further accurate a start operation-judging apparatus, to provide the start operation-judging apparatus that can be also applied to the race of a car such as a wheelchair, and to provide a sensor board for detecting start operation.
SOLUTION: A sensor 1 such as a strain gauge that is provided near a position where the deflection of a board on the surface of a sensor board 2 for detecting start operation is maximized is provided. An input signal obtained by A/D-converting the output signal of the sensor 1 is compared with two comparison signals obtained by smoothing and delaying the input signal and giving a threshold up and down to generate a detection signal. Time at the point of inflection of a comparison signal immediately nearby by going back from the second time that is delayed by specific time from the first time where a signal in detection is generated is specified. Based on it, a player obtains the starting point of the start operation, thus accurately obtaining the operation start point without any errors due to the threshold.
