摘要： A load change detection apparatus is provided with a base member, an elastic member, a first plate, a fixing member and heat flow sensors. The elastic member deforms according to a changed load applied to the elastic member, received by the receiving member. The first plate supports a surface of the elastic member on a side of the base member. The fixing member fixes the lower plate and the elastic member to the base member. The heat flow sensors, provided between the base member and the lower plate, output signals according to heat flowing between the lower plate and the base member. The heat flows due to heat generated or heat absorbed when the elastic member changes the elasticity shape thereof. Stress occurring when the elastic member deforms, is shut off by the first plate, thus direct transmission of the stress to the heat flow sensors is avoided.

摘要： There is disclosed a multiple axis load cell or controller in which axial and torsion measurements are decoupled while maximizing the outputs of both measurements. The active member of the load cell is a wheel with dual beams as the spokes. The wheel thus has four spokes or four beam members, each spoke is a pair of rectangular cross-section beams, orthogonal to each other. The beams have strain gages on the wide surfaces which measure the bending strain which is proportional to torsion or the axial input. There is an inner beam section and an outer beam section associated with each spoke and orthogonal to each other. The outer beams have the wide surface normal to the axis of the load cell. This beam section is more sensitive to the axial tension/compression input. The inner beam sections have their wide surface parallel to the axis of the load cell and are much less sensitive to bending but are sensitive to torsion. Therefore when a torsion or twisting motion is applied to the load cell, the inner beams with their wide surface parallel to the axis of the wheel are more sensitive and bend more. These beams experience bending as a result of the torsion input and have strain gages formed in a Wheatstone bridge arrangement to provide an output proportional to the torsion. The outer beams also have gages mounted thereon which are also wired in a Wheatstone bridge configuration and which Wheatstone bridge output of these gages are proportional to the axial force.

摘要： A semiconductor sensor device is formed using MEMS technology by placing a thin layer of single-crystal silicon, which includes semiconductor devices, over a cavity, which has been formed in a semiconductor material. The thin layer of single-crystal silicon can be formed by forming the semiconductor devices in the top surface of a single-crystal silicon wafer, thinning the silicon wafer to a desired thickness, and then dicing the thinned wafer to form silicon layers of a desired size.
