Abstract: A barrier operator feature enhancement device is designed to provide one or more features found in modern barrier operator devices and to incorporate those features into a previously installed barrier operator system. To facilitate ease of use, the barrier operator feature enhancement device can communicate with a large variety of barrier operators. Such communication may be wireless or wired, depending on the communication protocol implemented by a particular previously installed barrier operator. To facilitate the ease of installation, the device is designed to configure itself to operate with the communication protocol of the previously installed barrier operator. Once configured to be able to communicate with the previously installed barrier operator, the feature enhancement device works with the barrier operator to provide one or more additional features to enhance the capabilities of the previously installed barrier operator.

Abstract: An accessory for a garage door opener which includes a circuit which is energized when the garage door operator is actuated and which can be used to energize a power circuit as, for example, a lamp so as to provide illumination upon energization of the garage door operator. The lamp automatically turns off after a pre-set time and can also be manually controlled by an on-off switch.

Abstract: An improved digital radio control including a transmitter and receiver utilizing codes in which a plurality of switches at the transmitter and receiver establish a binary serially transmitted code for energizing only a particular receiver which has its switches set to the same binary code and wherein the different conditions of the binary code depend upon the pulse length such that unique codes can be selected for particular transmitters and receivers so that interference with other systems in the vicinity will not occur.
