Title: Movable barrier operator with multiple lighting schemes and method

Description:
TECHNICAL FIELD 
     This invention relates generally to movable barrier operators. 
     BACKGROUND 
     Movable barrier operators are well known in the art. Such mechanisms typically serve to use an electric motor to selectively move a movable barrier between open and closed positions. Such operators often have lighting associated therewith, either integral to the operator housing or physically separated from the operator housing. Many times such lighting will be activated by the operator for the duration of moving the movable barrier from one position to another plus some set period of time thereafter (such as four and one half minutes). 
     Such prior art solutions are adequate for some applications. There are, however, situations where such solutions are not fully suitable. For example, using the same amount of time to maintain the light in an illuminated state regardless of whether the movable barrier has just closed or just opened constitutes a compromise representing an average solution. Furthermore, present designs usually offer only a fixed selection of lights and a fixed orientation of those lights. Again, such designs are oriented towards satisfying a sense of average demand and not the specific needs of a specific user. Also, such prior art movable barrier operators typically provide a fixed lighting scheme; that is, regardless of what options may otherwise be available, the lights tend to illuminate and extinguish in accordance with an original built-in lighting scheme and offer little user opportunity to customize the scheme in any way.

     DETAILED DESCRIPTION 
     Generally speaking, pursuant to these various embodiments, a movable barrier operator is configured to have a plurality of ambient light drivers (such that lights can be operably coupled to the drivers to facilitate control of the lights via the movable barrier operator). In general, the movable barrier operator can operate in at least two modes of operation. When operating in a first mode of operation, the operator controls the ambient lights using a first control scheme. When operating in a second mode of operation, the operator controls the ambient lights using a second control scheme. The first and second control schemes are different from one another. 
     For example, the number of lights used for each mode of operation can be varied and/or the manner of use can be varied for some or all of the lights as used during each mode of operation. In a preferred embodiment, the user has an ability to readily select particular variations to thereby allow the user to customize the lighting functionality to accommodate a specific installation. In some embodiments, the mode of operation itself can vary to accommodate corresponding operational states of the movable barrier operator. This additional flexibility offers an even greater range of customization to the user. 
     Referring now to  FIG. 1 , a movable barrier operator  10  comprises a programmable platform as well understood in the art. Being programmable, the operator  10  can be readily modified to accommodate the functionality described herein. In this embodiment, a plurality of light drivers  11 A through  11 C are operably coupled to the movable barrier operator  10 . In particular, the drivers  11 A– 11 C have their actuation inputs coupled to corresponding outputs of the operator  10 . So configured, the operator  10  can actuate and switch off individual any of the light drivers  11 A– 11 C. Such light drivers are well understood in the art and include silicon controlled rectifier circuits, triac circuits, relay-based circuits and so forth; these drivers essentially serve to switch high voltage alternating current (such as 120 V AC) in response to low level direct current signals as typically provided by the logic circuits of a movable barrier operator. Given the relative familiarity of those skilled in the art with such drivers, additional detail will not be provided here for the sake of brevity and the preservation of focus. 
     In this embodiment, each light driver  11 A– 11 C couples individually to a corresponding ambient light source  12 A– 12 C, again as well understood in the art. Such light sources serve to provide ambient light to nearby surroundings (as versus, for example, merely serving to provide user-discernable signaling as occurs with light sources such as light emitting diodes). Various light sources can be successfully used herein, including incandescent, fluorescent, mercury vapor, sodium filament, and other as well. In addition, though only one light source is shown in this embodiment as being connected to a given light driver, if desired, additional light sources can be coupled to any given light driver as may be appropriate to a given application. In addition, as depicted, only three light drivers  11 A– 11 C are coupled to the movable barrier operator. If desired, additional (or fewer) light drivers can be used as appropriate. 
     In this embodiment, a wireless receiver  13  and a user interface  14  are also coupled to the movable barrier operator  10 . The wireless receiver  13  can be a typical movable barrier operator wireless receiver that receives appropriately modulated radio frequency signals that can include transmitter identification and/or user instructions regarding desired operation of the operator  10  and a corresponding movable barrier. Such a receiver  13  can also be used to support other functionality as described below in more detail. The user interface  14  can be as simple as a single switch or dual inline package switch (a so-called DIP switch) or as complex as a keypad, touchscreen display, or voice recognition mechanism as befits the needs of a given application. In at least some of the embodiments described below, this user interface  14  can serve to facilitate selection and/or programming of specific ambient light control schemes. 
     As depicted, the light drivers  11 A– 11 C are all physically coupled to the movable barrier operator  10 . Such an arrangement represents a fairly typical mode of installation. If desired, however, and referring now to  FIG. 2 , any given light driver signal  11  can be coupled to a transmitter  21  that transmits control signaling to a corresponding light source  12  via a wireless receiver  22  that controls a light driver  23  that is coupled to the light source  12 . With such an arrangement, the movable barrier operator  10  can control light sources that are otherwise difficult to physically couple to the operator  10  (such a circumstance can arise, for example, when retrofitting an installed movable barrier operator with additional light sources that are oriented at some distance from the operator). 
     So configured, the movable barrier operator  10  can receive user instructions via wireless signals or via the user interface  14 . Such instructions can facilitate desired operation of the various ambient light sources  12 A– 12 C that are under the control of the movable barrier operator  10  as described below in more detail. 
     Referring now to  FIG. 3 , a non-exhaustive illustrative example depicts a garage  30  having a movable barrier  31  comprising, in this example, a garage door. The movable barrier  31  can be moved between opened and closed positions by a motor and corresponding drive mechanism (not shown) as well understood in the art The motor in turn is controlled by a movable barrier operator  10  that is installed within the garage  30  (often through mounting on the ceiling of the garage  30 ). In this embodiment there are five light sources  12 A– 12 E that are coupled to the operator  10  via corresponding light drivers (as otherwise described with reference to  FIG. 1  but not shown here for purposes of clarity). Three of the light sources  12 A– 12 C are disposed within a housing  32  that contains at least a majority of the movable barrier operator  10  and two of the light sources  12 D and  12 E are located to the exterior of the housing  32 . For example, one light source  12 A can be disposed underneath the operator housing  32  to provide lighting directly below the housing. The other two housing-mounted light sources  12 B and  12 C can be side mounted to direct lighting from the approximate center of the garage  30  towards each of the individual parking positions therein (appropriate reflectors and/or lenses can of course be utilized to shape, diffuse, and direct such lighting as desired and as well understood in the art). The remaining two light sources  12 D and  12 E can be mounted on the ceiling of the garage  30  distal from the operator housing  32  and over a forward portion of the two parking positions to thereby, for example, improve illumination of the forward area where a user will park their vehicle. 
     It should be understood that this embodiment presents only one possible configuration for illustrative purposes only. Fewer or greater numbers of light sources could be used, either in a housing-mounted form factor or as separate outboard elements. In addition, light sources could also be disposed outside the garage  30  as desired. 
     Pursuant to the embodiment presented below, the operator  10  can control these various lights in various ways depending upon the specific operational mode and/or operational state of the movable barrier operator  10 . A few examples in this regard are as follows: 
     EXAMPLE 1 
     When the movable barrier operator  10  is placed into an OPEN mode of operation, the operator  10  could activate all of the light sources  12 A– 12 E. When the movable barrier operator  10  is placed in a CLOSE mode of operation, however, the operator  10  could instead activate only a single light source (such as the centrally positioned housing-mounted light source  12 A). 
     EXAMPLE 2 
     When the movable barrier operator  10  receives either an OPEN or CLOSE command via a wireless instruction from a specific user&#39;s remote transmitter (as is well understood in the art), the operator  10  can identify the user via the unique identification code that accompanies the command. By pre-assigning a specific side of the garage  30  to this specific user (for example, the right side of the garage  30  could be pre-assigned to the specific individual), the operator  10  can use this information to cause the corresponding light sources  12 C and  12 E for that side of the garage  30  to illuminate for the benefit of that specific user. Conversely, when a command is received from a second user who uses the left side of the garage  30 , only the light sources  12 B and  12 D are illuminated. 
     EXAMPLE 3 
     When a wireless-based command is received, the movable barrier operator  10  will effect the command while causing illumination of only three of the light sources  12 A,  12 D, and  12 E. When a user provides a command through a user interface switch  14 , however, the movable barrier operator  10  will effect the command while causing illumination of all five light sources  12 A– 12 E. 
     It should be clear that the movable barrier operator  10  can effect various lighting operational schemes to accommodate various operating modes and operational states. Such capability can be inflexibly programmed into the movable barrier operator  10  during manufacturing such that the operator  10  will always respond the same way to such stimuli. In a preferred embodiment, however, the operator&#39;s programmability is leveraged to at least permit a user to themselves associate a given lighting operational scheme (from amongst a plurality of such schemes) with a given operational mode or state and preferably to permit user programming of unique lighting operational schemes themselves. 
     With reference to  FIG. 4 , it should be clear that the movable barrier operator  10  functions, when implementing  41  a first mode of operation, will effect  42  a first lighting control scheme when facilitating  43  a first mode of operation. Similarly, and referring now to  FIG. 5 , the movable barrier operator  10  will, when operating  51  in a second mode of operation, effect  52  a second lighting control scheme when facilitating  53  a second mode of operation. As noted above, the various modes of operation can relate to specific actions of the operator (such as opening the movable barrier, closing the movable barrier, reversing movement of the movable barrier in response to detecting an obstacle, and so forth). It is also possible to correlate specific light schemes, however, with operational states of the movable barrier operator as well. 
     For example, and referring now to  FIG. 6 , the movable barrier operator  10  can detect  61  when either of two operational states  1  and  2  has been selected (for purposes of this example, the first operational state can be engaged when a first user transmits a command in conjunction with their unique identification code and the second operational state can be engaged when a second user transmits a command in conjunction with their unique identification code). When a first operational state is detected (for example, when the first user has used their wireless remote to transmit an OPEN command to the movable barrier operator  10 ), the operator  10  can then determine  62  a specific mode of operation as selected by the user (in this example, the mode of operation would be the OPEN mode of operation). The operator  10  would then implement  63  a corresponding first lighting control scheme (in this example, when opening the movable barrier for the first user, perhaps only two specific light sources are illuminated). 
     To continue this example, when the operational state is determined  61  to instead reflect reception of a wireless command from a second user, and the corresponding mode of operation is determined  64  to be the CLOSE operation, a second lighting control scheme is implemented  65  (for example, only a single light source, different than the two light sources used above, is actuated). 
     So configured, it should be understood that a large number of unique lighting schemes can be accommodated and correlated with various operating modes and/or operational states. Again, preferably, the movable barrier operator  10  is provided with a user interface  14  (or a sufficiently capable wireless interface) to permit a user to at least associate pre-stored lighting schemes with at least some operating modes/states and, if desired, to permit a user to specify and define custom lighting schemes to meet their specific needs. 
     Such a movable barrier operator  10  will support wide and varied lighting capability both at the time of installation and later (particularly as and when additional light sources are added to an existing movable barrier operator). Furthermore, such an operator  10  will readily accept alterations to whatever lighting schemes are selected. Such flexibility allows a user to modify the lighting response of the operator  10  to suit changing needs over time. 
     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.
