An impact force measurement associated with a test of a moveable barrier operator is obtained. An impact force signal representing the impact force measurement is generated. The impact force signal is received at a controller. Based upon the impact force represented by the signal, an adjustment of the at least one performance parameter of the moveable barrier operator is determined. The at least one parameter is then adjusted by the controller. A secondary protection device may thereafter be added as appropriate.

System and method for measuring force in a barrier operator system

A movable barrier operator having a microprocessor () or other programmable platform will automatically work in a safe and appropriate manner both with and without safe-operation sensors (). Once a safe-operation sensor is detected, the operator will thereafter function in a fashion that requires the continued presence of such sensor. In one embodiment, the operator state can be purposely reset to the initial operating state.

Automatic sensing of safe-operation sensor apparatus and method

A control unitresponds in ordinary course to external stimuli. In addition, the control unitfurther processes the external stimuli to characterize and otherwise seek to identify certain aspects and attributes. Unique audible signals that correspond to varying results of such analysis are then provided. These audible signals can readily facilitate ease and accuracy when diagnosing the cause of a particular operational issue. In one embodiment the diagnostic audible signals are selectively mutable without concurrently muting other audible signals as correspond to ordinary operation of the control unit

Audible diagnostic information apparatus and method

A control unitfor a movable barrier operator and having a user interface having a displaycan provide information on that displayof all presently blocked remote control transmitters without necessitating the display of any non-blocked transmitter information. In one embodiment the information is displayed one transmitter at a time, either automatically or in response to the user's actions.

Method and apparatus for displaying blocked transmitter information

A control devicefor use with another device (such as a movable barrier operator) has multiple memory interfacesandto permit the contents of one memory to be copied to another memory to thereby create an effective clone of the first memory. This copied memory is easily removable from the control deviceand thereafter stored separately as a back-up memory or used as the main memory in another control device. This effectively avoids a need for more tedious registration of authorized remote control transmitters in systems where the control deviceinterfaces with a movable barrier operator. In one embodiment, blocking information as corresponds to any of the otherwise registered transmitters can also be copied to the new memory when effecting this process.

Method and apparatus for memory cloning for a control device

A control unit responds in ordinary course to external stimuli. In addition, the control unit further processes the external stimuli to characterize and otherwise seek to identify certain aspects and attributes. Unique audible signals that correspond to varying results of such analysis are then provided. These audible signals can readily facilitate ease and accuracy when diagnosing the cause of a particular operational issue. In one embodiment the diagnostic audible signals are selectively mutable without concurrently muting other audible signals as correspond to ordinary operation of the control unit

A learning mode permits a device to register a plurality of transmitters (as part of authorizing such transmitters to act as remote control devices for use with a movable barrier operator ) without necessitating intervening user tactile inputs (as through a user interface keypad ) and without unnecessarily creating a security risk with respect to the duration of the learning mode. In one embodiment, duration of the learning mode is extended in response to detecting indicia that the learning mode continues to be used.
