Abstract: The invention includes a computer readable storage medium with executable instructions to run a segment of code and identify associated variables. The segment of code is stopped at a predetermined breakpoint and state values that correspond to the associated variables are identified. A variable is selected from the associated variables via a Graphical User Interface, where the selected variable has a variable state. The variable state is saved to a data store via the Graphical User Interface.

Abstract: A movable barrier operator having a motor controller (10) and motor (11) that control selective movement of a movable barrier (12) also has an obstacle detector (14) that utilizes an automatically determined excess force threshold value to permit reliable detection of an obstacle under a wide variety of operational circumstances, including changing physical circumstances, aging components, temperature variations, and motor runtime. In a preferred embodiment, a characteristic force value for the system is frequently updated as a function of actual measured force requirements (and further compensated, pursuant to various embodiments, with respect to other conditions such as temperature and motor runtime). This characteristic force value is then utilized to determine the excess force threshold value.
