【発明の名称】音波経過時間測定を利用する重量決定装置およびコンピュータ
Document Type and Number:
Japanese Patent JP2857251
Kind Code:
B2
Abstract:
A method and apparatus for determining of weight on a structure which utilizes an acoustic wave transmitting transducer and an acoustic wave receiving transducer. The elapsed time of transmission of the acoustic wave between the transmitting transducer and the receiving transducer varies according to the amount of weight on the load bearing member within the structure upon which the transducers are fixedly mounted. By determining of the elapsed time and comparing of such to a computer to a known weight versus elapsed time curve, the current weight can be determined for the structure.
