The present invention is remote control system including one or moree portable units and a base unit which employs identifiction codes for security. The operator preferably can select the identification code for the base unit, preferably via a process yielding a random number, with a provision for selection of a predetermined reset code. The base unit teaches this identification code to a portable unit via mating asynchronous communication ports. The same identification code may be taught to plural portable units. This identification code is stored in a static random access memory in the portable units and in an electrically erasable read only memory in the base unit and this is not susceptible to determination by visual inspection. Each portable unit includes a capacitor for storing energy so that the battery, which ordinarily supplies electrical power to the portable unit, can be replaced without loss of the stored identification code. Each portable unit may have plural buttons and plural memories enabling a portable unit to operate a plurality of base units. This may also enable a single portable unit to control a plurality of operations of a single base unit.

Remote control system with teach/learn setting of identification code

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.

Automatic garage door operator with remote load control

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 gargage 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 botton 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.
