Abstract
A system for determining the location of a patient on a support. The system includes a first and second sensor coupled to a patient's support surface and being at least laterally spaced. A first load signal from the first sensor has a first sensitivity greater than a second sensitivity of a second load signal from the second sensor. A determination circuit receives a first and second load signals and provides an indication of the location of the patient on the support surface from a comparison of the sum of the load signals to a selected value.
