Abstract
Described is a multi-optic scanner that can detect and/or measure weight placed on its vertical plate. In one embodiment, a portion of the vertical plate is positioned under a portion of a horizontal plate so that a force exerted on the vertical plate is transferred, whole or in part, to the horizontal plate. In alternate embodiments, one or more sensors are coupled to the vertical plate for detecting a force on the plate. The sensors can be coupled to an alert, such as an audible signal, to warn an operator of a misread weight.
Claims33
A scale comprising:
- a horizontal plate coupled to a load cell, said horizontal plate comprising a first extending member;
- and
- a vertical plate coupled to said load cell, said vertical plate comprising a second extending member, wherein said second extending member is positioned under said first extending member, and at least some force can transfer from said vertical plate to said horizontal plate.
A scanner comprising:
- a scan module;
- a horizontal plate coupled to a load cell, said horizontal plate comprising a first extending member;
- and
- a vertical plate coupled to said load cell, said vertical plate comprising a second extending member, wherein said second extending member is positioned under said first extending member, and at least some force can transfer from said vertical plate to said horizontal plate.
A scanner comprising:
- a scan module;
- a scale module comprising a horizontal plate coupled to a load cell;
- a vertical plate;
- a sensor coupled to said vertical plate that can detect a force on said vertical plate;
- and
- an alert that can warn a scanner operator.
A method of measuring a force on a scanner comprising:
- providing a horizontal plate coupled to a load cell, said horizontal plate comprising a first extending member;
- and
- transferring at least some force from a vertical plate to said horizontal plate, wherein said vertical plate is coupled to said load cell and said vertical plate comprises a second extending member, wherein said second extending member is positioned under said first extending member.
A method of detecting a force on a vertical plate of a scanner comprising:
- providing a scale module comprising a horizontal plate coupled to a load cell;
- detecting a force by a sensor coupled to a vertical plate;
- and
- transmitting a signal to operate an alert to a scanner user.
