This invention relates generally to movable barrier operators and more particular to movable barrier operators having a remote transmitter learning mode.
Movable barrier operators of various kinds are known in the art. Some movable barrier operators provide automated (and/or remote) control with respect to movement of a movable barrier (such as, but not limited to, a single-piece or segmented garage door, a sliding or pivoting gate, a pivoting guard arm, rolling shutters, and the like). Such control systems generally serve to provide some point of control with respect to a mechanism that itself governs, in some fashion, access to some further destination (such as, but not limited to, a garage or other parking area, a business area, a recreation or exercise area, and so forth).
For purposes of security many such movable barrier operators are configured to respond only to a previously authorized remote transmitter as versus any remote transmitter that might otherwise be able to communicate compatibly with the movable barrier operator. By one common approach an authorized remote transmitter transmits one or more codes by which the movable barrier operator can determine the authorized status of the remote transmitter. Such codes may be relatively static or may change, at least in part, pursuant to a shared algorithm (with so-called rolling codes comprising a common example of the latter).
Many movable barrier operators have a learning mode of operation and more particularly a remote transmitter learning mode of operation. When operating in this remote transmitter learning mode a movable barrier operator can learn the code that characterizes and identifies a particular corresponding remote transmitter. Thereafter, when operating in an ordinary mode of operation, the movable barrier operator can identify such a remote transmitter as being an authorized source of remote transmitter-sourced barrier movement control signals. This, in turn, permits having the movable barrier operator respond to that barrier movement control signal.
In many cases a programmer will place a movable barrier operator into this learning mode through physical manipulation of a corresponding user interface. This user interface often comprises one or more switches, buttons, or the like on the movable barrier operator itself. This location is chosen in order to make it somewhat difficult to inadvertently learn a transmitter through unplanned actuation of the learning mode. A corresponding difficulty, however, is that this location places the programmer or the programmer's equipment (such as a ladder or the like) at risk of damage if the movable barrier operator is activated. The damage can arise from a reaction to being startled by the motion or by undue engagement with the movable barrier itself and/or with moving portions of the movable barrier operator while the programmer is located near to the movable barrier operator in order to effect manipulation of that user interface.
By one prior art approach, the movable barrier operator must first lose (or otherwise cease receiving) an original remote transmitter-sourced barrier movement control signal and then receive a subsequent remote transmitter-sourced barrier movement control signal before the movable barrier operator will be permitted to respond. In the majority of cases this precaution will serve adequately to protect the programmer from the aforementioned risks, but this approach can nevertheless be supplemented further.
For example, in some cases a given movable barrier operator will be able to detect a loss-of-signal event within 0.5 seconds or less. This can lead to operational circumstances where the subsequent remote transmitter-sourced barrier movement control signal can be received very quickly after cessation of a first remote transmitter-sourced barrier movement control signal. This, in turn, can lead to a responsive action on the part of the movable barrier operator within a very brief period of time (typically less than one second) following conclusion of a learning mode action. A given programmer may be unable to move away from the movable barrier operator quickly enough under such circumstances to more fully ensure avoidance of risks such as those noted above.
The above needs are at least partially met through provision of the programmer protection method and apparatus for use with a movable barrier operator described in the following detailed description, particularly when studied in conjunction with the drawings, wherein:
Skilled artisans will appreciate that elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions and/or relative positioning of some of the elements in the figures may be exaggerated relative to other elements to help to improve understanding of various embodiments of the present invention. Also, common but well-understood elements that are useful or necessary in a commercially feasible embodiment are often not depicted in order to facilitate a less obstructed view of these various embodiments of the present invention. It will further be appreciated that certain actions and/or steps may be described or depicted in a particular order of occurrence while those skilled in the art will understand that such specificity with respect to sequence is not actually required. It will also be understood that the terms and expressions used herein have the ordinary meaning as is accorded to such terms and expressions with respect to their corresponding respective areas of inquiry and study except where specific meanings have otherwise been set forth herein.
Generally speaking, pursuant to these various embodiments, when a movable barrier operator detects a predetermined state with respect to a remote transmitter learning mode, the movable barrier operator can respond by temporarily requiring at least a first programmer protection duration of time to pass before permitting the movable barrier operator to respond to a remote transmitter-sourced barrier movement control signal. By one approach this first programmer protection duration of time is longer than a loss-of-signal detection duration as characterizes the movable barrier operator.
The precise nature of the predetermined state can vary with the needs and/or capabilities of a given application setting. As one example, the predetermined state can comprise initiation of the remote transmitter learning mode. By one approach, the first programmer protection duration of time can comprise a period of time that begins with a conclusion of the remote transmitter learning mode and that concludes a predetermined amount of time thereafter. By another approach, if desired, the first programmer protection duration of time can comprise a period of time that begins with a conclusion of a last received remote transmitter transmission and that concludes a predetermined amount of time thereafter.
So configured, a programmer will more likely be ensured of having a longer minimum period of time within which to remove themselves from proximity to the movable barrier operator following usage of the movable barrier operator's learning mode. The particular duration of time employed in a particular setting can be varied to suit the likely dynamics of a particular application setting.
By one approach, if desired, these teachings can also provide for receiving an otherwise authorized remote transmitter transmission from a given remote transmitter during the first programmer protection duration of time. In response to such an event, if desired, the movable barrier operator can then automatically unauthorize the given remote transmitter such that subsequent remote transmitter transmissions from the given remote transmitter will not be heeded in the absence of subsequent reauthorization of the given remote transmitter.
So configured, these teachings can additionally serve to permit a given programmer to quickly correct an unintended or mistaken authorization event for a given remote transmitter as may have occurred during a given learning session. In some cases this comprises an increase in convenience with respect to accomplishing such an event. In other cases this provides a mechanism to achieve this result where another approach may not have been otherwise available.
By yet another approach, when a movable barrier operator detects a predetermined state with respect to a remote transmitter learning mode, the movable barrier operator can respond by disabling the movable barrier operator from responding to a remote transmitter-sourced barrier movement control signal until a second event, such as physical manipulation of a corresponding user interface, occurs. Upon detecting this second event, the movable barrier operator can again be permitted to respond to remote transmitter-sourced barrier movement control signals.
These and other benefits may become clearer upon making a thorough review and study of the following detailed description. Referring now to the drawings, and in particular to
Upon detecting 101 this predetermined state with respect to a remote transmitter learning mode, however, this process 100 can optionally accommodate having the movable barrier operator learn 102 to recognize at least one remote transmitter during the remote transmitter learning mode. Such an accommodation can be appropriate, for example, when the predetermined state comprises initiation or activation of a remote transmitter learning mode. This learning 102 can further comprise, if desired, learning to recognize a plurality of remote transmitters during such a remote transmitter learning mode (that is, if desired, one can accommodate learning a plurality of remote transmitters during the course of a single given learning session).
Those skilled in the art will understand that there are numerous known ways by which such learning can be carried out and that other ways will likely be developed in the future. As these teachings are not particularly sensitive to the selection of any particular approach in this regard, for the sake of brevity additional elaboration regarding specific learning techniques or approaches will not be presented here.
In any event, in response to detecting 101 the predetermined state of the remote transmitter learning mode, this process 100 provides for temporarily requiring 103 at least a first programmer protection duration of time to pass before permitting the movable barrier operator to respond to a remote transmitter-sourced barrier movement control signal. With momentary reference to
This first programmer protection duration of time can comprise, if desired, a duration of time that begins with a conclusion of the remote transmitter learning mode and that concludes a predetermined amount of time (such as, for example, the aforementioned 30 seconds) thereafter. By another approach (and again as desired) this first programmer protection duration of time can comprise a period of time that begins with a conclusion of a last received remote transmitter transmission and concludes a predetermined amount of time thereafter. It would also be possible to employ both of these possible approaches and/or to tether the first programmer protection duration of time to some other event, state, or condition of interest if desired.
So configured, these teachings can aid in protecting a programmer from untoward interactions with the movable barrier operator and/or a corresponding movable barrier. In particular, a transmission from a recently learned remote transmitter are largely prevented from causing a responsive movement when such a transmission occurs at a time that is perhaps more likely to correspond to when the programmer is physically proximal to the movable barrier operator itself as often ordinarily occurs during a remote transmitter learning process.
As one illustrative example, and referring now to
As another illustrative example, however, and referring now to
Referring again to
If desired, this process 100 can also accommodate using the first programmer protection duration of time to de-authorize a previously authorized remote transmitter. For example, this process 100 can provide for detecting reception 105 of an otherwise authorized remote transmitter transmission from a given remote transmitter during the first programmer protection duration of time and to then automatically unauthorize 106 that given remote transmitter such that subsequent remote transmitter transmissions from that remote transmitter will not be heeded in the absence of subsequent reauthorization of the given remote transmitter. By one approach, if desired, this automatic unauthorization can comprise preparing to unauthorized the given remote transmitter and then, upon detecting subsequent initiation of the remote transmitter learning mode, responsively completing the unauthorization of this remote transmitter.
This can be helpful and useful, for example, when a programmer has a plurality of remote transmitters and inadvertently causes the movable barrier operator to learn a particular remote transmitter that, in fact, is not intended for authorized use with that movable barrier operator. At present, such de-authorization can be cumbersome or may not be a supported function by any means. This optional feature provides a relatively simple, effective, and intuitive mechanism by which such an action can be accomplished. If desired, this process 100 can further accommodate providing 107 a programmer discernable signal (such as any of those previously noted above) to indicate when such unauthorizing occurs or is about to occur).
If desired, an over-ride mechanism 500 can be provided to supplement (or to substitute for) the above described processes. As is already described above, a movable barrier operator can be configured to respond to detection of a predetermined state of interest as corresponds to a remote transmitter learning mode. With reference to
The distance between such a user interface and the movable barrier operator can of course vary with the particular circumstances of a given application setting but will typically be a distance that is at least sufficiently remote so as to require the programmer to remove themselves from physical proximity to the movable barrier operator in order to effect the required physical manipulation of the user interface.
Upon detecting 501 such a physical manipulation, this process 500 can then provide for re-enabling the ability of the movable barrier operator to respond to remote transmitter-sourced barrier movement control signals. In the case where this process 500 is used in conjunction with the previously described process 100, this re-enablement can occur notwithstanding that the first programmer protection duration of time has not yet passed.
If desired, such re-enablement can be further conditioned by a preceding requirement 502 that at least predetermined threshold amount of time have passed. This predetermined threshold amount of time may comprise, for example, a second programmer protection duration of time that may, for example, be less than the first programmer protection duration of time discussed above. For example, the first programmer protection duration of time could be 60 seconds and the second programmer protection duration of time could be 30 seconds.
Those skilled in the art will appreciate that the above-described processes are readily enabled using any of a wide variety of available and/or readily configured platforms, including partially or wholly programmable platforms as are known in the art or dedicated purpose platforms as may be desired for some applications. Referring now to
In this illustrative example a movable barrier operator 600 comprises a receiver 601 that is configured and arranged in accordance with prior art knowledge to operate compatibly with one or more wireless remote transmitters 602. The latter may comprise, for example, handheld devices or a sunshade-mounted device that a person can use to cause a movable barrier, such as a garage door, to move in a desired direction. This movable barrier operator 600 also comprises a remote transmitter learning mode state detector 603 and a memory 605.
The remote transmitter learning mode state detector 603 serves to detect the desired predetermined state of a remote transmitter learning mode as described above. By one approach, such a detector 603 can be operably coupled to (or rendered otherwise responsive to) a user interface 604 that serves to facilitate, for example, initiation of a remote transmitter learning mode.
The memory 605, by one approach, has stored therein a first programmer protection duration of time as described above. As already described, this first programmer protection duration of time may represent a duration of time (such as but not limited to a duration of time that is at least 30 seconds in length) that is longer than a loss-of-signal detection duration that may otherwise characterize the operation of the movable barrier operator 600. When this platform serves to support the optional remote user interface interaction process 500 described above, this memory 605 can also have stored therein the aforementioned second programmer protection duration of time.
A programmer protection circuit 606 operably couples to the receiver 601, the remote transmitter learning mode state detector 603, and the memory 605. By one approach this programmer protection circuit is configured and arranged to temporarily require at least the first programmer protection duration of time to pass before permitting the movable barrier operator to respond to a remote transmitter-sourced barrier movement control signal following detection of the aforementioned predetermined state as corresponds to the remote transmitter learning mode of operation. For example, by one approach, this can comprise temporarily requiring at least the first programmer protection duration of time to pass beginning with a conclusion of the remote transmitter learning mode of operation. As another example, by another approach, this can comprise temporarily requiring at least the first programmer protection duration of time to pass beginning with a conclusion of a last received remote transmitter transmission.
If desired, this programmer protection circuit 606 can be further configured and arranged to provide for automatically unauthorizing a given remote transmitter upon receiving an otherwise authorized remote transmitter transmission from a given remote transmitter during the first programmer protection duration of time. This, in turn, would cause the movable barrier operator to not heed subsequent remote transmitter transmissions from that remote transmitter unless and until that remote transmitter were reauthorized. As noted above, such unauthorizing can comprise, if desired, initially preparing to unauthorize the remote transmitter and then completing such unauthorization in response to detecting, for example, initiation of the remote transmitter learning mode.
If desired, this movable barrier operator 600 can also optionally comprise a programmer discernable signal 607. This can comprise an audible signal, a visual, and/or a haptic signal as may best suit the needs and requirements of a given application setting. Such a signal can be used, for example, to indicate when the first programmer protection duration of time has not yet passed and/or to indicate one or more steps or states during the aforementioned unauthorization steps, to note but a few useful examples.
As noted above, this platform 600 may also operably couple to a remotely located user interface 608 such as, but not limited to, a wall-mounted switch that is located, for example, near a door leading from a garage into a connected residence. It is the physical manipulation of such a remotely located user interface 608 that can serve as a trigger for the above-described corresponding process 500.
Those skilled in the art will recognize and understand that such an apparatus 600 may be comprised of a plurality of physically distinct elements as is suggested by the illustration shown in
Those skilled in the art will appreciate the added protection that may be achieved via these teachings. It will also be appreciated that these teachings may be further leveraged to increase the capabilities and functionality of a given movable barrier operator. These teachings are also readily implemented using readily available technology in a highly cost effective manner.
Those skilled in the art will recognize that a wide variety of modifications, alterations, and combinations can be made with respect to the above described embodiments without departing from the spirit and scope of the invention, and that such modifications, alterations, and combinations are to be viewed as being within the ambit of the inventive concept.
