Multi-channel remote control transmitter
First Claim
1. A hand-held multi-channel remote control transmitter for transmitting a selected one of a plurality of possible channel codes preassigned for particular functions in a security system, comprising:
- a transmitter housing;
a transmitter circuit for transmitting encoded radio frequency (RF) signals;
at least one user-actuated channel select switch mounted for convenient access by the user without opening said housing and having on and off states;
a user-actuated transmit switch mounted for convenient access by the user without opening said housing and having on and off states; and
a controller responsive to the states of said channel select and said transmit switches, said controller comprising;
means responsive to the number of times said channel select switch is actuated for providing a channel select count value;
means responsive to actuation of said transmit switch only when power is applied to the controller for providing a predetermined channel code in dependence on said channel select count value, where in actuation of said transmit switch is not operative to supply power to said controller, and wherein a different predetermined channel code corresponds to each channel count value, and for actuating said transmitter circuit to transmit a signal encoded with said selected channel code,whereby said transmitter is capable of transmitting a selected one of a plurality of possible channel codes in dependence on the number of times said channel select switch is actuated.

Abstract
A multi-channel remote control transmitter is disclosed for control of apparatus such as vehicle security systems, garage door openers, and the like. The transmitter provides the capability of selecting one of many different channels or codes to be transmitted with a minimum number of control switches. The transmitter includes at least one channel select switch and a transmit switch. The user actuates the channel select switch to select a desired channel, and then actuates the transmit switch to actually transmit the selected channel code. The transmitter includes an audible or visual indicator for confirming to the user the particular channel selected. The transmitter provides an audible "battery low" signal when the battery voltage drops below a predetermined level.

32. A hand-held multi-channel remote control transmitter for a security system for transmitting a selected one of a plurality of possible channel codes, comprising:
-
a transmitter housing; a channel select switch and a transmit switch mounted for convenient access by the user without opening said housing, said switches having "on" and "off" states; a transmitter circuit for transmitting encoded radio frequency (RF) signals; a battery for providing electrical power to said transmitter; means responsive only to actuation of said channel select switch to the "on" state for powering up the transmitter controller; a controller responsive to the states of said channel select and transmit switches, said controller comprising; means activated on powering up of said controller for maintaining electrical power to said controller for a predetermined time interval after release of said channel select switch; means responsive to actuation of said channel select switch for providing a channel select count value, said means comprising means for incrementing or decrementing the count value each time said switch is actuated; means responsive to actuation of said transmit switch only when power is applied to the controller for providing a predetermined channel code in dependence on said channel select count value, wherein a different predetermined channel code corresponds to each channel count, and for actuating said transmitter circuit to transmit a signal encoded with said selected channel code; and means for turning the power to said controller off a predetermined time after the last actuation of said transmit or channel select switch. - View Dependent Claims (33, 34)
