Abstract
In a movable barrier operator, data that corresponds to force requirements to effect desired movement of a movable barrier is compressed and stored for later retrieval. Multiple compression schemes and/or compression rates can be made available. Selection of a given scheme or rate can be determined on a user-directed or an automatic basis. Automatic selection in turn can be based on various criteria including, for example, presently available memory resources.
Claims35
A movable barrier operator comprising:
- a movable barrier controller;
- at least a first movable barrier force sensor input operably coupled to the movable barrier controller;
- a first memory operably coupled to the movable barrier controller, which first memory at least includes compressed data that corresponds to force data as regards movement of a movable barrier;
- a second memory operably coupled to the movable barrier controller, which second memory at least includes at least a portion of the compressed data in uncompressed form.
1 more element
A method comprising:
- at a movable barrier operator:
- detecting force as corresponds to travel of a movable barrier during at least portions of the travel to provide sensed force information;
- compressing information that corresponds to at least some of the sensed force information to provide compressed force information;
- storing the compressed force information;
- uncompressing at least some of the compressed force information.
2 more elements
A movable barrier controller comprising:
- operator means for controlling movement of a movable barrier;
- force sensor means operably coupled to the operator means for detecting an amount of force as is currently being applied to effect movement of the movable barrier;
- position determination means operably coupled to the operator means for determining a present respective position of the movable barrier;
- data compression means operably coupled to the operator means for compressing force information to provide compressed force information;
- memory means operably coupled to the operator means for storing the compressed force information and at least a portion of the compressed force information in uncompressed form.
