In a work machine, a load information output part outputs a load calculated by a load calculation part as load information before a piston member shifting toward a stroke end reaches a specific position, and a load storage part stores the load calculated by the load calculation part as a specific load when the piston member shifting toward the stroke end reaches the specific position. The load information output part further outputs the specific load as the load information after the piston member shifting toward the stroke end enters a specific region.

A load sensor having a centrally disposed aperture element through which a fastening element of a vehicle air suspension assembly passes to affix the load sensor between the vehicle air suspension assembly and the vehicle suspension, wherein the load sensor has a force measurement sensor disposed proximate an elongate slot to generate a load signal which varies based on an amount of strain in the load sensor, wherein the load signal received by a load calculator allows calculation of the load exerted from the vehicle frame to the vehicle suspension.

A weight sensing assembly for a semi-trailer truck enabling balancing of a load includes a sensing module, which is one of a plurality thereof. The sensing modules are mountable to wheels of the semi-trailer truck so that each axle has a sensing module engaged to outside wheels thereof. The sensing module obtains a pressure measurement of a tire engaged to the wheel and transmits it to an electronic device. Programming code on the electronic device enables it to utilize a pressure change, upon positioning of a load upon the semi-trailer truck, to determine a weight that is positioned upon an associated axle. The electronic device calculates adjustments to positions of a sliding fifth wheel and of sliding tandems of the semi-trailer truck to obtain positions thereof that will achieve a legal weight distribution of the load. The electronic device presents, upon a screen thereof, the adjustments to a user.

A load estimation system for a tire is provided. The tire includes a pair of sidewalls extending to a circumferential tread and supports a vehicle. A sensor is mounted to the tire and measures an inflation pressure of the tire and a footprint length of the tread. A vehicle loading state estimator determines a loading state of the vehicle. An inflation correction factor is determined from the vehicle loading state. A pressure correction module receives the measured footprint length, the measured inflation pressure, and the inflation correction factor, and determines an adjusted footprint length. A de-noising module processor receives the adjusted footprint length to generate a filtered footprint length, and a wear correction module receives the filtered footprint length and corrects for wear of the tire to generate a wear-corrected footprint length. A load determination model receives the wear-corrected footprint length and determines an estimated load on the tire.

The methods and systems provide for increasing the accuracy of aircraft weight and center of gravity determination through the use of filtered strut pressure measurements. Aircraft vertical and horizontal accelerations are determined as the aircraft is taxiing, and used to identify and reduce the number of significantly distorted pressure measurements, to allow the lesser distorted pressure measurements to be averaged, and a lesser number of distorted pressure measurements to be averaged; further identifying the aircraft in near-neutral acceleration and strut pressure values near-neutral of strut seal friction distortions. Pressure sensors, accelerometers, and an inclinometer are mounted in relation to landing gear struts to monitor, measure and record strut pressure as related to strut telescopic movement, rates of strut telescopic movement and aircraft vertical and horizontal accelerations; experienced by landing gear struts, as the aircraft proceeds through typical ground and taxi operations.
