摘要： The invention is a load cell (20) for the measurement of force, independent of displacement, created by means such as weight, acceleration, pressure, and the like. The load cell (20) has a beam structure with beams positioned parallel to each other in at least one plane. Generally, these parallel beams (42, 45) are attached to a stationary base (40) and have sensing means (52) attached between the two beams (42, 45). In operation, deflection of one beam creates a response in the sensing means due to the relative action or deflection in the second beam.

摘要： A load cell assembly (20) includes a load cell body (10) having a pair of sensors (15a, 15b) mounted therein which provide complementary output signals in response to a force applied to the load cell body. A linearization and common mode discrimination routine (50) analyzes changes in the sensor outputs and characterizes the changes as being either primarily due to applied force or primarily due to common mode effects. A force value, indicative of the applied force on the load cell body, is updated only for changes in the sensor outputs which are primarily due to applied force. However, changes which are primarily due to common mode effects are not incorporated into force value calculations, whereby common mode effects are rejected.

摘要： A composite load cell (30) utilizes end blocks (60, 62) mounted to the ends of a load cell body (32) to increase the apparent bulk modules of the end beams (34, 36) on the body. The increased modules of the end beams improves cornering of the load cell, and further aids in the rejection of moment induced shears, including those due to off-center loading, thereby increasing the usable resolution of the load cell.

摘要： A load cell device includes a load cell structure formed of a suitable metal and including vertically spaced apart, generally parallel horizontal elements (14, 15) integrally formed with longitudinally spaced apart, generally parallel vertical elements (12, 13). Flexures (16, 17) interconnect each horizontal element with the vertical elements. A bending beam (18) extends between and is interconnected with the horizontal or vertical elements. When a load is applied vertically and perpendicularly to one of the horizontal elements, the load cell structure will elastically deform as a parallelogram to thereby transfer shear force to the bending beam to cause shearinduced bending of the latter. Strain gages or frequency resonator crystal elements sense the shearinduced bending and are embodied in electronic circuitry which produces an output signal caused by deformation of the bending beam. The electronic circuitry is operable to convert the output signal to a perceptive force readout.

摘要： A low profile electronic bathroom scale (10) includes a base (17) having a pair of elongate rigid deformable members (16) affixed thereto. The end portions of the deformable members (16) are spaced from the base and define cantilevered beams having a plurality of strain gauges (34-39) secured to the respective upper surfaces thereof. A rigid deck (11) is secured to the ends of the deformable members (16) by Z-shaped clips (29) so that the weight of a person on the deck is transferred to the deformable members (16), causing the latter to deform, and imposing a strain on the strain gauges. The bridge circuit output signal is converted into a perceptive weight read-out (45).

摘要： A force sensitive scale and dual sensor load cells for use therewith isolate, measure, and reject out residual rejected effects from the output of the scale. By isolating residual rejected effects, the overall accuracy of the scale may be improved, and the scale may be made substantially insensitive to the position of an object on the scale. In addition, where a scale includes multiple load cells coupled in parallel to a load receiving member and spaced apart in the direction of the force vector, the outputs of the load cells may be effectively scaled to cancel out frictional effects inherent in the scale.

摘要： The invention is directed to a counting scale which implements a load cell assembly (20) for the measurement of weight used in counting calculations. A load cell in such an assembly has a beam structure with beams positioned parallel (42, 45) to each other in at least one plane. Generally, these parallel beams (42, 45) are attached to a stationary base (40) and have sensing means (52) attached between the two beams (42, 45) and the base (40). These sensing means (52) are preferably resonators (52) which have resonant frequencies that vary in response to an applied force on the load cell (20). A controller (200) is included in the assembly to drive these resonators (52), convert their frequency outputs to digital values, and correct for various environmental effects, to obtain an accurate weight measurement for use in the counting scale.
