  • Electronic scale assembly having incorporated spreader arm
    Patent number: 7022921
    Abstract: An electronic scale/spreader arm assembly for use with an apparatus includes an axial force transducer, such as a load cell, that is attachable to the apparatus. A spreader bar is configured to receive a support wherein the spreader bar and the load cell are interconnected such that the load cell is pivotally attached to the apparatus and the spreader arm is pivotally attached to the support while the spreader arm and the load cell are attached to one another such that non-axial loads imparted to the spreader arm will not be transmitted to the axial force transducer.
    Type: Grant

  • Weighing apparatus and method
    Patent number: 6956175
    Abstract: A scale including an event data discrimination and collection system for continuously monitoring a weight of an infant placed on the scale platen, which may be configured as a bed. Load cells are used to continuously monitor infant weight from time placed on the scale platen, so that sudden apparent weight spikes sensed by the load cells but attributable to events involved in patient care may be discarded as artifact, while gradual weight changes reflective of infant physiology are accumulated by the scale controller and used to provide a current weight for the infant.
