Claims 2-3, 5-15, 17-18 and 20-26 were not reexamined.
1. A remote controlled barrier opening system, comprising:
a transmitter configured to:
(a) switch an output frequency to different channels, the switching being performed at a transmitter-switching rate, and
(b) on each of the channels, transmit multiple copies of a message;
a receiver configured to:
(a) switch a reception frequency to the different channels at a receiver scan rate that is different from the transmitter-switching rate, and
(b) on each of the channels, receive data for a period of time greater than a transmission time of one copy of the message; and
a barrier operator configured to operate a device at least in part in response to receipt of a copy of the message on any of the different channels.
