Abstract: A system for testing a pressure sensor of a seat includes a loading device and a processor. The loading device removably applies weight to the seat. The processor receives a measurement of a pre-installation pressure offset of a bladder of the pressure sensor measured before installation of the pressure sensing assembly into the seat. The processor is programmed to receive a weighted measurement from the pressure sensor in the seat when the loading device applies weight to the seat and an empty seat measurement from the pressure sensor in the seat when the loading device does not apply weight to the seat. The processor determines a threshold value by subtracting the empty seat measurement from the weighted measurement. The processor determines a seat pressure offset value by subtracting the pre-installation pressure offset value from the threshold value. The processor compares the seat pressure offset value to a selected range.

Abstract: A controlled lean system for a tree feller-buncher includes a sensor configured to measure an orientation of a boom coupled to the tree feller-buncher, and a felling head operably connected to the boom. A controller is operable to detect a cut tree carried by the felling head and to estimate a quantity of tree lean needed to reduce torsional load during rotation of the boom while carrying the cut tree based at least in part on the measured orientation of the boom.

A fluid-sealed chamber (40) in which a measurement liquid is hermetically enclosed is provided between a first member (8) and the bearing raceway ring (25) which is disposed near the mounting section (9). Pressure acting on the fluid to be measured changes as the bearing raceway ring (25) moves in the cylinder-axis direction, the bearing raceway ring (25) being disposed near the mounting section (9). The fluid-sealed chamber (40) is provided with a pressure sensor (44) capable of detecting a change in the pressure of the fluid to be measured.

Abstract: A technique facilitates measurement of forces resulting from a variety of loads, stresses, temperatures, or other sources. In an embodiment, the system comprises a load cell constructed with channels extending into a component which may be subjected to forces. Sensors cooperate with the channels to detect changes in volume of the channels as an indicator of the forces acting on the component. In some applications, the channels enclose a liquid, and the sensors comprise pressure sensors which detect changes in pressure within the liquid due to the volumentric changes in the channels. The system also may comprise a compensation system which compensates for external influences, such as temperatures and hydrostatic pressures.
