1. A monitoring system for monitoring a patient in a patient-support apparatus, the system comprising:
- a first detector operable to detect electromagnetic radiation within a detection field, the detection field including a patient supporting area on the patient-support apparatus;
at least one standard configured to be supported on the patient-support apparatus for movement therewith, positioned in the detection field, the standard conveying electromagnetic radiation having a predetermined signature to the detector; and
a controller coupled to the detector, the controller including a processor and a memory device coupled to the processor;
the memory device including instructions that, when executed by the processor, cause the controller to evaluate data received from the detector to compare all of the electromagnetic radiation in the detection field, including the patient supporting area, to the signature of the standard and determine if changes in the electromagnetic radiation are indicative of movement of a person in the detection field.

Abstract
A monitoring system for monitoring a patient in a patient-support apparatus includes a detector, a standard, and a controller. The detector detects electromagnetic radiation in a field. The standard conveys a predetermined electromagnetic signature to the detector. The controller monitors the electromagnetic radiation in the field and compares the electromagnetic radiation to the standard to determine the position of a patient supported on a patient-support apparatus positioned in the field.
