SYSTEM AND METHOD FOR WIRELESS CONTROL OF MEDICAL DEVICES

摘要

A system 100 and method 800 for controlling a body-scanning device with a wireless footswitch 110 is disclosed. The method includes polling a status of a plurality of switches 114 on a wireless footswitch 110 using a microprocessor 122. A pulsed signal is sent from the microprocessor 122 to a watchdog timer U7. The pulsed signal is pulsed at a predetermined rate when the microprocessor 122 is operating within selected operating parameters. The microprocessor 122 is reset when the pulsed signal is pulsed at a rate less than the predetermined rate. The status of the plurality of switches 114 on the wireless footswitch 110 is transmitted to a receiver 138 connected to the scanning device 130 to enable the scanning device 130 to be controlled by actuating at least one of the plurality of switches 114 on the wireless footswitch 110.
