Patent US4934468 - Hospital bed for weighing patients - Google Patents
A hospital bed has a support frame and a weigh frame mounted on the support frame by load cells. The output of the load cells is summed to provide a reading of the total weight on the weigh frame. The tare weight is subtracted to provide the patient's weight....http://www.google.com/patents/US4934468?utm_source=gb-gplus-sharePatent US4934468 - Hospital bed for weighing patients
