RFID - Based Wireless Remote Control Using Variable ID Field
First Claim
Patent Images
1. A TV remote control (RC) powered using RFID principles from an electric field generated by a controlled component, comprising:
- a housing containing no batteries;
plural command elements on the housing and manipulable by a person;
a processor receiving signals indicating manipulation of a command element, the processor establishing an ID field for a data packet based on what command element is indicated as having been manipulated, wherein no more than two command elements are associated with the same ID such that at least a first command element is associated with a first ID and at least a second command element is associated with a second ID different from the first command element; and
one and only one RFID tag in the RC sending the packet under control of the processor to the controlled component.

Abstract
A TV remote control is powered using RFID principles from an electric field generated by the TV and so the RC requires no batteries. The RC changes the ID field of the data packet it transmits based on what button was pushed so that a first button is associated with a first ID, a second button is associated with a second ID, and so on. In this way, only a single RFID tag need be provided in the RC.

6. A method comprising:
-
powering, using an electric field generated by a component, a batteryless remote control (RC) having plural keys, at least first and second keys being associated with respective first and second IDs; receiving a first signal indicating manipulation of the first key; in response to receiving the first signal, configuring a first command packet to have the first ID and a data field; sending the first command packet to the component to cause the component to execute a command associated with the first command packet; receiving a second signal indicating manipulation of the second key; in response to receiving the second signal, configuring a second command packet to have the second ID and a data field; and sending the first command packet to the component to cause the component to execute a command associated with the first command packet. - View Dependent Claims (7, 8, 9, 10)

11. A system comprising:
-
a component to be controlled; an RFID reader assembly in the component to be controlled and generating an electric field; a portable remote control (RC) powered by the electric field; plural command elements on the RC; wherein in response to manipulation of a command element, a data packet is generated in the RC with an ID field correlated to the command element such that an ID in the ID field depends on what command element is manipulated, such that at least a first command element is associated with a first ID and at least a second command element is associated with a second ID different from the first command element; and an RFID tag in the RC sending the packet to the controlled component. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
