WIRELESS CONTROL SYSTEM AND METHOD

摘要

A wireless control system and method is disclosed. The system includes a controlled device having a wireless communication system, the wireless communication system including a source of an interrogating field and a reader. The wireless control system also includes a control device having one or more manual inputs and a modulator for modulating the interrogating field with a coded signal. The modulated interrogating field is detected by the reader in the controlled device and the controlled device wireless operation with the control device is enabled based on the coded signal received from the control device if the control device is within a predetermined distance as determined by the received modulated interrogating field.

主权项

1. A method for short range wireless control, comprising:
wirelessly transmitting an interrogating field from a controlled device; receiving the interrogating field at a control device having one or more manual inputs and modulating the interrogating field with a coded signal; detecting the modulated interrogating field at the controlled device; and controlling the controlled device operation based on the coded signal if the control device is within a predetermined distance determined by the modulated interrogating field received from the control device.
