  • Load sensing system with flexure plate
    Patent number: 9024212
    Abstract: A load sensing system having at least one load sensing assembly, each assembly including a flexure plate with an upper region extending along a longitudinal length of the flexure plate, a lower region disposed below the upper region, and at least one flex region disposed between the upper region and the lower region. The lower region defines a mounting feature for an end of a weigh idler and is capable of substantially only lateral movement relative to the upper region. Each assembly further includes a load cell and a bracket having a first end rigidly connected to a force transmission surface of the load cell and having a second end rigidly connected at a plurality of areas to the upper region of the flexure plate to rigidly capture the upper region while suspending the remainder of the flexure plate.

  • Object oriented customer information exchange system and method
    Patent number: 6078325
    Abstract: A computer-based information exchange system permits customers to request and receive different types of information from various sources. The operation of the system is controlled by an application created using object oriented techniques. These techniques permit simple and straightforward creation and modification of complex automation tasks involving numerous action-object pairs.
