Abstract: An operating system for a motorized barrier includes an operator for controlling movement of the barrier between various positions. The operator may receive wireless signals from a wireless or wired wall station transmitter, a wireless keyless entry device and/or a portable remote transmitter device. The system also includes a device such as a light kit or switch that controls a load, wherein the device is capable of also receiving wireless signals to control the kit or the load. And the transmitters are capable of generating wireless signals receivable by the operator and the device for independent operation of each.

Abstract: A method and related system for enabling receipt and storage of data by an operator from at least two types of transmitters, is disclosed. The method includes designating a number of records in a memory array; sub-dividing the memory array into at least two groups, wherein each group is associated with a specific type of transmitter. The method concludes by determining whether one of the number of records is available for writing of data to a specific one of the transmitters.

Abstract: A motorized barrier operator system that moves a barrier between limit positions includes a barrier, a motor coupled to the barrier and adapted to move the barrier between a full open limit position, a danger zone position, and a full close position. The system further includes a position sensor coupled to one of the barrier and the motor to detect the positions, and a force sensor coupled to one of the barrier and the motor to detect an actual force value during movement of the barrier. A controller is connected to the sensors which determines a first threshold response value between the full open limit position and the danger zone position, and a second threshold response value between the danger zone position and the full close limit position. The second threshold response value is less than the first threshold response value, and the controller commands the motor to at least stop movement of the barrier if the actual force value is greater than either of the threshold response values.

Abstract: A method and system for setting a downward force adjustment exerted by a barrier is disclosed. As is known, the barrier operator initiates corrective action if a detected obstruction force is deemed excessive. The inventive method and system comprises pre-setting a force threshold value used by the barrier operator. While in a programming mode, the barrier is moved from one limit position to another limit position. A recorded value is determined during the moving of the barrier and the threshold value is adjusted until equal the recorded value. A feedback device such as a light or a speaker is used to indicate when the threshold value is at least equal the recorded value.

Abstract: A method for controlling a motorized barrier operator after detecting an obstruction includes the steps of providing a motorized barrier operator that moves a barrier between limit positions and providing at least one control switch that upon actuation moves the barrier in a direction toward one of the limit positions. Actuation of the at least one control switch during movement of the barriers at least causes the barrier to stop. If an obstruction is detected by the motorized barrier operator during movement of the barrier, the operator allows only uni-directional movement of the barrier, regardless of actuation of the at least one control switch, after the detecting step.
