Abstract
Disclosed a load measurement system (100) includes a compartment (110), a damper (112) and a weight calculation unit (131). The damper (112) is configured to be positioned between the compartment (110) and a platform (121) and to compress at a predetermined rate based on a load of the compartment (110). The weight calculation unit (131) is configured to calculate a weight of the compartment (110) based on the compression of the damper (112).
Claims22
A load measurement system, comprising:
- a compartment;
- a damper configured to be positioned between the compartment and a platform and to compress at a predetermined rate based on a load of the compartment;
- and
- a weight calculation unit configured to calculate a weight of the compartment based on the compression of the damper.

A damper, comprising:
- an upper plate configured to be attached to a compartment;
- a lower plate configured to contact a platform;
- a first spring located between the upper plate and the lower plate;
- and
- an elastic filler surrounding the first spring, wherein the first spring and the elastic filler are configured to compress at a predetermined rate based on a force being exerted against the upper plate and the lower plate.
2 more elements
A method, comprising:
- compressing a damper between a compartment and a platform;
- sensing a compression distance of the damper, corresponding to a difference between a non-compressed state and a compressed state based on the compressing of the damper;
- and
- calculating a weight of the compartment based on the compression distance of the damper.
