Abstract
A portable scale including an inflatable bladder, an inflation port, a pressure sensor, and a display. The display indicates the weight of an object that may be placed upon the bladder based on the pressure inside the bladder that is sensed by the pressure sensor. The bladder may be deflated for easy transport or storage. The portable scale may further include a mechanical or electric pump for inflating the bladder. The pump may be turned off when the pressure inside the bladder reaches a predetermined level.
Claims14
A portable scale comprising:
- a bladder;
- an inflation port for introducing a gas into the bladder;
- a pressure sensor in communication with the interior of the bladder for sensing pressure inside the bladder;
- and
- a display in communication with the pressure sensor for indicating the weight of an object placed on the bladder, wherein
- the weight of the object is a function of the pressure inside the bladder created by the weight of the object and that is sensed by the pressure sensor.
