Weighing apparatus that quantifies amount of impact
First Claim
1. A weighing apparatus including a weighing unit on which a weighing object is placed and a mass sensor that receives its mass×
- acceleration of gravity as a load and measures mass from an electrical signal corresponding to displacement of an internal structure of the apparatus at that time, comprisingimpact load quantifying means that quantifies and records an amount of the displacement, determines acceleration by a numerical calculation from said displacement amount data, and records said acceleration as a degree of impact received by the mass sensor on placement, for judging whether the measurement apparatus is used in an impulsive manner by a comparison with a value of a manually placed static load.

Abstract
A weighing apparatus is provided that quantifies an impact load based on an electrical output from a mass sensor to prevent damage to the mass sensor by disclosing the degree of impact to a user. The weighing apparatus includes a weighing unit on which an object is placed and a mass sensor that receives the mass×acceleration of gravity of the object as a load and measures mass from an electrical signal corresponding to displacement of an internal structure of the apparatus. The apparatus quantifies and records the amount of the displacement, and determines acceleration by a numerical calculation from the displacement data. The obtained acceleration quantifies the amount of impact applied on the weighing apparatus by the object, and may be used to warn the user when the weighing apparatus is in danger of damage.
