Patent ID: 6956175

Claim:
An apparatus for monitoring weight of a patient, comprising: a scale platen; at least one sensor for providing output data indicative of changes in weight supported by the scale platen; a microprocessor programmed to: (1) store an initial output data segment as an initial data record indicative of an initial weight supported by the scale platen in memory, (2) receive subsequent output data segments indicative of each subsequent weight change over a period of time, (3) sort the subsequent output data segments into one of at least two categories responsive to both: (a) a duration of time during which each subsequent output data segment is generated and (b) a magnitude of each subsequent output data segment, (4) discard output data segments sorted into at least one category, and (5) apply output data segments in the at least another category to a previously determined and stored cumulative output data record to update the data record.
