发明名称 Automatic garage door operator with remote load control
摘要 The present invention is an automatic garage door operator with a two button portable controller enabling a secure mode and control of a load remote from the door operator. In accordance with the normal operation of the secure button, actuation when the garage door is closed toggles a secure mode between secure and non-secure states. In the secure state the automatic garage door operator does not move the door upon receipt of a door signal. To open the door when in the secure state the operator must first press the secure button to enter the non-secure state and then press the door button to open the door. The secure button has a secondary function when the garage door is open and the secure state is prohibited. Actuation of the secure button when the door is open toggles the state of a load remote from the automatic garage door operator between an on state and an off state. This control is achieved via a signal modulated on the electric power main.
