1. An improved mobile or vehicle mounted device for measuring weight or force comprising:
- a cantilever beam secured or affixed at one end to the vehicle or mobile platform, with an array of multiple gauges or sensors placed at known locations on or in said beam substantially near to a secured end, so as to detect a local tensile stress or strain and a local compressive stress or strain in the beam outboard of the sensors;
wherein the ratios of outputs from the array of multiple gauges or sensors can be used to determine weight or force applied anywhere along said beam;
where the local compressive stress and the local tensile stress are measured substantially simultaneously;
where the individual sensors are pressed into a receiver hole formed or cut into the cantilever beam;
where the receiver hole is formed around each sensor; and
where each receiver hole substantially forms a cylindrical shape around each sensor.

Abstract
An improved device for the measuring of weight or force is disclosed. This is an apparatus that allows for measurement of weight or force using a cantilever beam that is substantially insensitive to location of the weight or force within certain limits on the beam and is capable of correction for off-level conditions.

8. A scale mounted on a mobile platform comprising:
-
(a) a cantilever beam secured or affixed at one end to a mobile platform; (b) two gauges or sensors placed at known locations near said secured or affixed end of said cantilever beam, and positioned along the upper portion of said cantilever beam, said sensors being placed either internally to said cantilever beam or externally secured to said cantilever beam, said sensors or gauges being of a type to detect and measure a first local tensile stress and a second tensile stress or strain in said cantilever beam outboard of said sensors or gauges; (c) two gauges or sensors placed along the lower portion of cantilever beam, corresponding in location as measured from the end of said cantilever beam to the locations of the sensors placed along the upper portion of said cantilever beam, said sensors likewise being placed either internally to said cantilever beam or externally secured to said cantilever beam, said sensors or gauges likewise being of a type to detect and measure a first local compressive stress and a second compressive stress or strain in said cantilever beam outboard of said sensors and gauges; (d) an attachment capable of receiving a force or load to be measured, said attachment located outboard of the location of said gauges or sensors on the opposite end of said cantilever beam than the secured or affixed end; (e) the individual output signals of said gauges or sensors and uses a mathematical formulae based on the ratio of the individual output signals to calculate the weight or force applied to said cantilever beam; (f) where the local compressive stress and the local tensile stress are measured simultaneously; and (g) where the individual sensors are pressed into a receiver hole formed or cut into the cantilever beam. - View Dependent Claims (9, 10)

11. A method, comprising:
- securing a cantilever beam to a vehicle or mobile platform, the cantilever beam having an array of multiple gauges or sensors placed at known locations on or in said beam substantially near to a secured end of the cantilever beam, so as to detect a local tensile stress and a local compressive stress or strain in the beam outboard of the sensors;
where the individual sensors are pressed into a receiver hole formed or cut into the cantilever beam. - View Dependent Claims (12, 13, 14, 15)
