APPARATUS AND METHOD FOR WEIGHING THE OCCUPANT OF A BED

摘要

Weighing apparatus (1) which is comprised of at least two weight sensing elements (12) that are connected to each other by at least one communication cable (48) and are preferably positioned either adjacent to or at each end of bed in order to support bed. In one embodiment, each weight sensing element (12) comprises a weight sensing base (11) and at least a pair of mounting assemblies (7) that may be at or adjacent to the head and foot of bed. Preferably, weight sensing base (11) extends laterally and mounting assemblies (7) extend vertically. Each weight sensing base (11) is supported by the corresponding pair of mounting assemblies (7). The method of operation of weighing apparatus is based on a two-mode operation: TARE mode operation and WEIGH mode operation. The principals of operation of weighing apparatus are a summation of load points that are established when bed, under its own controls, is lowered to a position that allows bed and its contents to rest on weighing apparatus.
