Wireless appliance activation transceiver
First Claim
1. A system for wirelessly activating an appliance, the appliance associated with an appliance receiver for receiving a wireless activation signal, the appliance responding to one of a plurality of transmission schemes, the system comprising:
- a receiver section separate from the appliance receiver, the receiver section operative to receive a radio frequency activation signal;
a transmitter operative to transmit a radio frequency activation signal;
at least one user activation input, each activation input identifying a wireless channel;
memory holding data describing a plurality of rolling code transmission schemes associated with a rolling code mode and a plurality of fixed code transmission schemes, at least one fixed code transmission scheme associated with each of at least one fixed code mode; and
control logic in communication with the receiver section, the transmitter, the at least one user activation input and the memory, for each channel the control logic maintaining a channel mode set initially to a rolling code mode, the channel mode changing to one of the at least one fixed code mode if the channel is trained to a fixed code in response to receiving a signal transmitted from an existing transmitter, the control logic in response to an assertion of the user activation input associated with the channel generating and transmitting an activation signal based on each transmission scheme associated with the mode maintained for the channel.

Abstract
A universal remote control transmits one of a plurality of sequences of activation signals when activated. The remote control includes a receiver and a transmitter. At least one wireless channel is associated with a user activation input. Memory holds data describing rolling code transmission schemes and fixed code transmission schemes. Control logic maintains a channel mode set initially to a rolling code mode. The channel mode changes to one of at least one fixed code mode if the channel is trained to a fixed code. In response to an assertion of the user activation input for a particular channel, the control logic generates and transmits an activation signal based on each of a plurality of transmission schemes associated with the mode programmed for the channel.

12. A method for use in a wireless appliance activation transceiver system having a transmitter section and a receiver section, the method controlling an appliance activated by a radio frequency activation signal received by an appliance receiver and described by a transmission scheme, the transmission scheme one of a plurality of possible transmission schemes including a plurality of rolling code transmission schemes and a plurality of fixed code transmission schemes, the method comprising:
-
establishing a mode as rolling mode in the transceiver system; if a fixed code in a radio frequency activation signal received by the receiver section from an existing transmitter is detected, storing the detected fixed code and changing the mode to fixed mode; receiving in the transceiver system an activation request from a user; if the mode is rolling mode, generating in the transceiver system and transmitting from the transmitter section to the appliance receiver a sequence of activation signals, each activation signal based on one of the plurality of rolling code transmission schemes; and if the mode is fixed mode, generating in the transceiver system and transmitting from the transmitter section to the appliance receiver at least one activation signal, each of the at least one activation signal based on one of the plurality of fixed code transmission schemes, each of the at least one activation signal including the stored fixed code. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
