Title: Variable adjustable door latch

Description:
CROSS-REFERENCE TO RELATED APPLICATION AND CLAIM FOR PRIORITY 
     This application is a continuation-in-part of and claims the benefit of co-pending U.S. patent application Ser. No. 12/789,989, filed on May 28, 2010, entitled “Efficient And Safe Door Locking Control In Power-Off And Power-On Conditions”, the entirety of which is incorporated herein by reference. 
    
    
     TECHNICAL FIELD 
     The subject specification relates generally to door latches, and in particular to variable adjustable door latches. 
     BACKGROUND 
     Certain areas (e.g., rooms, secured production areas, etc.) can be accessed via a door (e.g., swinging door, sliding door, etc.), wherein, as desired, a particular defined physical area can be secured by employing a lock, a sensor, and/or other device on the door to the defined physical area. For example, an electromagnetic lock can be used to lock a door to a defined physical area, where the defined physical area can be used, for example, for storage of product, for production line operations, etc. Often, it can be desirable to be able to latch the door to hold the door in a desired position (e.g., closed position) in relation to the door frame, where, for example, the door can then be locked to facilitate securing the defined physical area. 
     One type of conventional door latch accomplishes latching of the door by using an electromagnet with variable current. Certain issues can arise when using such conventional door latches. For instance, such a conventional door latch consumes energy while producing the latching. Also, a loss of power creates a loss of latching by such door latch. Due in part to these drawbacks, such conventional door latches may not be suitable and/or may not be allowed in certain applications, such as some safety applications, for example. Another type of conventional door latch accomplishes latching of the door using a permanent magnet, wherein the magnet is integrated with the lock. With this type of conventional door latch, it is not possible to vary the latching conditions without degrading the locking quality of the lock (e.g., safety lock). Also, some conventional door latches are integrated with door stops, wherein such door latches may allow for some adjustment. However, such conventional door latches do not allow for adjustment of the door latch while at the same time allowing for predictable and desirable force profile settings. 
     It is desirable to be able to hold or latch a door in a desired locational position (e.g., closed position) in relation to a door frame with a desired amount of force without consuming power to produce the force, while, for example, a safety switch or safety lock associated with the door is activated, and at the same time, providing a stop for the door. It also is desirable to be able to intelligently adjust the amount of latching force used to hold the door in the desired locational position. It is further desirable to reduce or minimize shock to a device, such as a lock, sensor, or switch, attached to the door frame (or door), during closing of the door, to facilitate reducing or minimizing harm to or operational problems with such device. 
     SUMMARY 
     The following discloses a simplified summary of the specification in order to provide a basic understanding of some aspects of the specification. This summary is not an extensive overview of the specification. It is intended to neither identify key or critical elements of the specification nor delineate the scope of the specification. Its sole purpose is to disclose some concepts of the specification in a simplified form as a prelude to the more detailed description that is disclosed later. 
     Systems, methods, and devices that can efficiently employ a power efficient door latch/door stop arrangement are presented. In an aspect, a door latch/door stop system can comprise a first bracket component (e.g., door frame bracket component) that can be attached to a door frame, and a second bracket component (e.g., door bracket component) that can be attached to a door (e.g., swinging door, sliding door, etc.) associated with the door frame. In an aspect, the first bracket component and/or second bracket component can be made from a desired material(s), such as a ferromagnetic material(s), which can be attracted to a magnetic force when applied thereto, although accordance with other embodiments, another desired material(s) can be employed. The first bracket component can be have a desired shape (e.g., rectangular, square, etc.) and size, wherein, for example, the first bracket component can be desirably attached to the door frame and be large enough in size such that a desired portion of the first bracket component can overhang beyond the door frame and into the doorway so that the first bracket component can be employed, in part, as a door stop and door latching mechanism for the door, which can be associated with (e.g., attached to a side of, in the sliding groove of) the door frame, when the door is being closed. 
     In an aspect, the second bracket component can be shaped (e.g., substantially rectangular or square shaped with regard to the main body of the second bracket component) and sized, as desired, wherein there can be an extended portion (e.g., tongue, tag) that can extend out from the main body of the second bracket component, and wherein the extended portion can be employed to facilitate stopping and latching of the associated door, for example, when the extended portion comes in contact with a holder component (e.g., magnet component) associated with the first bracket component, as more fully disclosed herein. 
     The system can further comprise one or more holder components, which can be attached or adhered to a recessed area(s), for example, at or near an edge of the first bracket component. In an embodiment, a holder component can be or can include, for example, a permanent magnet that can produce at least a desired amount of force (e.g., magnetic force) to facilitate attracting and holding the extended portion of the second bracket component against the holder component to thereby hold or latch the door in a desired predefined locational position (e.g., a specified location) in relation to the door frame when the door is closed. The predefined locational position can be a desired locational position in relation to an operation device (e.g., lock, such as an electromagnetic lock; a sensor; a switch; etc.), which can be attached to the first bracket component and/or second bracket component. 
     In accordance another embodiment, the holder component, when contained on the first bracket component, can comprise a vacuum cup that can apply a desired amount of force to a surface (e.g., extended portion) of the second bracket component (or conversely, the first bracket component (e.g., in the recessed area), when the holder component is contained on the second bracket component) (e.g., via the vacuum or suction force generated by applying the vacuum cup to a surface of the second bracket component) to latch or hold the door in the desired locational position. In still another embodiment, the holder component can be a Velcro liner, which can be attached to the first or second bracket component, wherein a Velcro receptor can be attached to the other of the first or second bracket component, and the Velcro liner can come in contact with the Velcro receptor when the door is closed such that a desired amount of latching force is created by the Velcro liner being attached to the Velcro receptor to hold the door in the desired locational position. 
     As an example of the door stopping/door latching system, the operation device can be an electromagnetic lock, wherein the lock component, which can include the lock pin (e.g., lock bolt) and solenoid actuator, can be attached to the first bracket component (e.g., on the portion of the first bracket component that overhangs beyond the door frame), and a lock receptacle, which can have a hole that can receive the lock pin to the lock the door, when desired, can be attached to the second bracket component. When closing and locking the door, the overhanging portion of the first bracket component can act as a door stop for the door, so that the door stops when it comes in contact with the overhanging portion of the first bracket component, and the extended portion of the second bracket component comes in contact with the holder component, wherein the magnetic force of the holder component can hold or latch the extended portion to thereby latch the door and hold the door closed in the desired predefined locational position. The predefined location position can be selected such that, when the door is in that position, the lock pin of the lock component and the hole in the lock receptacle can be desirably aligned in relation to each other so that when the lock component is switched to the locked state, the lock pin can engage or be inserted in the hole in the lock receptacle to lock the door with respect to the door frame. 
     In accordance with an aspect, the amount of latching force applied by the holder component to the extended portion of the second bracket component can be controlled and varied based at least in part on the amount of overlap of the extended portion on the surface of the holder component there is when the door is in the latched position (e.g., when at least a portion of the extended portion is in contact with the surface of the holder component). As desired, the extended portion can be adjusted or moved in relation to the holder component associated with the first bracket component to facilitate adjusting the amount of latching force the holder component applies to the extended portion. The second bracket component can have extended or substantially rectangular or oblong screw guides (e.g., holes wherein a screw(s) can be inserted to attach the second bracket component to the door), wherein the second bracket component, including the extended portion, can be moved along the screw guides to adjust the amount of overlap the extended portion has on the holder component in the closed position until the extended portion has a desired amount of overlap with the holder component to result in the desired amount of latching force in the closed position, wherein the screws can be tightened to the door to attach the second bracket component to the door at the point along the screw guides that results in the desired amount of overlap of the extended portion on the holder component. 
     In another aspect, the extended portion of the second bracket component can be shaped and sized as desired to facilitate creating or adjusting the force profile of the extended portion and the system overall. For instance, the extended portion can be respectively shaped to have a force profile that is linear (or substantially linear) or non-linear with regard to adjusting the latching force based at least in part on adjustments of the amount of overlap of the extended portion in relation to the holder component. For example, when the extended portion has a rectangular or square shape, the force profile can be linear or at least substantially linear, such that, as the extended portion is moved in a direction resulting is less overlap with the holder component, there can be a linear or substantially linear reduction in the amount of latching force applied by the holder component to the extended portion, and, as the extended portion is moved in a direction resulting is more overlap with the holder component, there can be a linear or substantially linear increase in the amount of latching force applied by the holder component to the extended portion. As another example, instead of a rectangular or square shaped extended portion, the extended portion can have one edge or corner (or both edges or corners) rounded, or can be shaped in a triangular shape, which can create a non-linear force profile, such that, as the extended portion is moved in a direction resulting is less overlap with the holder component, there can be a non-linear (e.g., square function, exponential function, etc.) reduction in the amount of latching force applied by the holder component to the extended portion, and, as the extended portion is moved in a direction resulting is more overlap with the holder component, there can be a non-linear increase in the amount of latching force applied by the holder component to the extended portion, wherein the non-linear force profile can be based at least in part on the particular shape of the extended portion and the amount of overlap of extended portion on the holder component. 
     In yet another aspect, the second bracket component can include, or can have adhered thereon (e.g., using a suitable adhesive material), a force level guide that can show the respective amounts of latching force that can be achieved at respective positions of the extended portion of the second bracket component in relation to the holder component associated with the first bracket component. The force level guide can comprise a set of force level lines or grooves that each has a respective force level associated with that particular line or groove (e.g., first line indicates 10 Newtons (N), second line indicates 20 N, third line indicates 30 N, etc.). When the second bracket component is adjusted or moved about its screw guides to adjust the amount of overlap of the extended portion in relation to the holder component, the force level guide can indicate the amount of latching force that corresponds with the position of the second bracket component in relation to the holder component and/or associated operation device. The user can view the amount of latching force indicated on the force level guide so the user can be informed as to the amount of latching force and can adjust the second bracket component, and thereby the amount of latching force, to achieve the desired amount of latching force. The respective levels indicated by the force level guide and the placement of the corresponding force level lines or grooves can be determined based at least in part on the shape of the extended portion and the magnetic force of the holder component. In accordance with various embodiments, the force level guide can be formed on the second bracket component, wherein, for example, force level lines can be formed in or on a surface of the second bracket component (e.g., surface facing outward when attached to the door; or the force level guide can be formed on a force level plate, which can be formed of metal, polymer-based material, paper, or other desired material, and can be attached or adhered to the surface of the second bracket component). 
     In still another aspect, the first bracket component can function as a shock or force absorber for an operation device attached to the first bracket component. For instance, the first bracket component, with the overhanging portion that overhangs beyond the door frame, can function as a type of cantilever, wherein the material that forms the first bracket component can have at least some level of elasticity, and when the door impacts and is stopped by the overhanging portion of the first bracket component, the first bracket component can absorb at least a portion of the impact of the door, which can reduce the amount of shock, vibration, or force that is impacted on (e.g., transferred to) the operation device. In an embodiment, if desired, a shock absorber component, which can be fabricated from a desired material(s) (e.g., polymer-based material, felt, etc.) and can have a desired thickness and shape (e.g., shape that corresponds to the shape of the surface of the overhanging portion with which the shock absorber component will be in contact and/or the shape of the side of the operation device with which the shock absorber component will be in contact), can be inserted between the first bracket component and the operation device to provide further shock or force absorption to thereby further reduce the amount of shock, vibration, or force impacted on the operation device when the door impacts (e.g., comes in contact with) the overhanging portion of the first bracket component when the door is being closed. 
     In yet another aspect, the system can comprise an operation integrity component that can sense conditions associated with the first bracket component and second bracket component, the door and associated door frame, and/or operation devices attached to the first bracket component or second bracket component to facilitate securing the door and associated defined physical area, as desired, and maintaining desirable operation of the system. In an embodiment, the operation integrity component can be associated with a sensor component (e.g., magnetic field sensor, which can be or can comprise a Reed switch or Hall-effect sensor, in accordance with various embodiments) that can be associated with (e.g., connected to, implanted in) the recessed area of the first bracket component (or, in another embodiment, in the extended portion of the second bracket component) and can sense whether recessed area (or the extended portion) is in a magnetized state or non-magnetized state and/or sense the amount of magnetic field or force applied to recessed area (or the extended portion) by the holder component, wherein, for example, the holder component can be attached to the extended portion and can apply a desired latching force to the recessed area (or another component formed thereon or attached thereto), or alternatively, can be attached to the recessed area and can apply a desired latching force to the extended portion. When the door is open, the sensor component can sense that the amount of magnetic force applied to or experienced by the recessed area (or the extended portion) is low (e.g., below a minimum threshold magnetic force level that indicates the door is properly closed) and can transmit a signal (e.g., feedback signal) that indicates the door is in an open state. When the door is closed properly, the sensor component can sense that the amount of magnetic force applied to or experienced by the recessed portion (or the extended portion) is at least the minimum threshold latching force level and can transmit a signal that indicates the door is in a closed state. The feedback signal can serve as a Magnetic Bond Sensor (MBS) output as well as a Door Status Switch (DSS) for the door latch. The sensor component can be useful, for example, when a lock component with a lock pin is attached to the first bracket component and a lock receptacle is attached to the second bracket component, as the sensor component can indicate when the second bracket component and associated lock receptacle are in the desired predefined locational position in relation to the lock pin associated with the first bracket component, so that when the lock pin is moved to the locked position, the lock pin can successfully engage the hole in the lock receptacle. 
     Also, over time and/or for other reasons, the door may become misaligned, and, as a result, which can cause misalignment of the recessed area (or the extended portion) in relation to the holder component, and also can cause misalignment of the lock pin in relation to the hole in the lock receptacle, which can negatively affect operations associated with the door (e.g., door is unable to be locked because the lock pin is not able to engage the hole in the lock receptacle). The misalignment of the recessed area (or the extended portion) in relation to the holder component can result in a change in the strength of the magnetic field. The sensor component can detect the magnetic field strength at or on the recessed area (or the extended portion), and can send feedback relating to the detected magnetic field strength, for example, to a computer system. The computer system can analyze the feedback information and can identify that the magnetic field strength has changed to an undesirable level, and can determine that the door is misaligned or at least is likely misaligned, or that the recessed area (or the extended portion) is not in proper alignment with the holder component, and a maintenance ticket can be issued to have a maintenance person check out the door and the door latch/door stop system and correct any defect so that the system operates properly. 
     The following description and the annexed drawings set forth certain illustrative aspects of the specification. These aspects are indicative, however, of but a few of the various ways in which the principles of the specification can be employed. Other advantages and novel features of the specification will become apparent from the following detailed description of the specification when considered in conjunction with the drawings.

     DETAILED DESCRIPTION 
     The disclosed subject matter is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed subject matter. It can be evident, however, that the disclosed subject matter can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing the disclosed subject matter. 
     As used in this application, the terms “component,” “module,” “object”, “system,” or the like can refer to hardware (e.g., lock housing, lock pin, magnet, etc.) and/or a computer-related entity, either hardware, a combination of hardware and software, software, or software in execution. For example, a component can be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration, both an application running on a controller and the controller can be a component. One or more components can reside within a process and/or thread of execution and a component can be localized on one computer and/or distributed between two or more computers. As another example, an interface can include I/O components as well as associated processor, application, and/or API components. 
     Typically, operation devices, such as door locks, can be employed to secure doors and defined physical areas associated with the doors. Often, it can be desirable to be able to latch the door to hold the door in a specified position (e.g., a predefined locational position when closed) in relation to the door frame, where, for example, the door can then be locked, to facilitate securing the defined physical area. One type of conventional door latch accomplishes latching of the door by using an electromagnet with variable current. Certain issues can arise when using such conventional door latches, as for example, such a door latch consumes energy while producing the latching and loss of power creates a loss of latching. Due in part to these drawbacks, such conventional door latches may not be suitable and/or may not be allowed in certain applications, such as some safety applications, for example. Another type of conventional door latch accomplishes latching of the door using a permanent magnet, wherein the magnet is integrated with the lock. With this type of conventional door latch, it is not possible to vary the latching conditions without degrading the locking quality of the lock. Also, some conventional door latches are integrated with door stops, wherein such door latches may allow for some adjustment. However, such conventional door latches do not allow for adjustment of the door latch while at the same time allowing for predictable and desirable force profile settings. 
     To that end, systems, methods, and devices that efficiently stop and latch a door are presented. In an aspect, a first bracket component can be attached to a door frame and can have an overhang portion, comprising a holder component (e.g., permanent magnet), that can extend into the doorway to act as a door stop when the door is moved from the open position to the closed position in relation to the associated door frame. In another aspect, the second bracket component, which can comprise an extended portion (e.g., tongue, tag), can be desirably adjusted in position in relation to the holder component and attached to the door such that the extended portion has a desired amount of overlap on the holder component, wherein the amount of overlap can correspond to an amount of latching force (e.g., magnetic force) between the holder component and the extended portion in accordance with the force profile associated with the extended portion and based at least in part on the shape of the extended portion, wherein differently shaped extended portions can have different force profiles. In an embodiment, the holder component, by employing a permanent magnet to apply a desired amount of magnetic force to the extended portion (e.g., to magnetically attract and hold the extended portion), can desirably maintain latching without requiring power to thereby conserve power and maintain latching during power off conditions associated with the door. In still another aspect, an operation device (e.g., electromagnetic lock, sensor, switch, etc.) can be attached to the first bracket component (e.g., electromagnetic lock, comprising a solenoid actuator and lock pin, can be attached to the first bracket component) and/or second bracket component (e.g., lock receptacle associated with the lock can be attached to the second bracket component) and the door latching can hold the door in the desired predefined locational position to facilitate operations of the operation component. 
     Now referring to  FIG. 1 , illustrated is a diagram of an example system  100  that can efficiently stop and latch a door in accordance with various aspects and embodiments of the disclosed subject matter. In an aspect, the system  100  (e.g., a door latch/door stop system) can comprise a first bracket component  102  (e.g., door frame bracket component) that can be attached to a portion of a door frame (not shown in  FIG. 1 ; e.g., as shown in  FIGS. 3 ,  5 A, and  5 B) at a desired location on the door frame. The system  100  also can include a second bracket component  104  (e.g., door bracket component) that can be attached to a door (e.g., swinging door, sliding door, etc.) (not shown in  FIG. 1 ; e.g., as shown in  FIG. 5A ) associated with the door frame. In an aspect, the first bracket component  102  and/or second bracket component  104  can be made from a desired material(s), such as a ferromagnetic material(s), which can be attracted to a magnetic force when a magnetic force is applied thereto. The first bracket component  102  can be have a desired shape (e.g., rectangular, square, etc.) and size, wherein, for example, the first bracket component  102  can be large enough in size such that a portion of the first bracket component  102  can be desirably attached to the door frame and a desired portion of the first bracket component  102  can overhang and/or extend beyond the door frame and into the doorway so that the first bracket component  102  can be employed, in part, as a door stop and door latching mechanism for the door, which can be associated with (e.g., attached to a side of, in the sliding groove of) the door frame, when the door is being closed. That is, when the door is being closed, the door can come in contact with the overhanging portion of the first bracket component  102  and the first bracket component  102  can stop the door at that point. 
     In an aspect, the second bracket component  104  can be shaped (e.g., substantially rectangular or square shaped with regard to the main body of the second bracket component  104 ) and sized, as desired, wherein there can be an extended portion  106  (e.g., tongue, tag) that can extend out from the main body of the second bracket component  104 . The extended portion  106  can be employed to facilitate stopping and latching of the associated door, for example, when the extended portion  106  comes in contact with a holder component  108  (e.g., magnet component) associated with the first bracket component  102 , as more fully disclosed herein. 
     It is to be appreciated and understood that, while the subject specification generally discloses that the first bracket component  102  is attached to a door frame and the second bracket component  104  is attached to a door, the subject specification is not so limited, as, in accordance with another embodiment, the first bracket component  102  can be attached to the door and the second bracket component  104  can be attached to a door frame. 
     The system  100  can further comprise one or more holder components  108 , which can be attached or adhered to a recessed area(s)  110 , for example, at or near an edge of the first bracket component  102 . In an embodiment, a holder component  108  can be or can include, for example, a permanent magnet that can produce at least a desired amount of force (e.g., magnetic force) to facilitate attracting and holding the extended portion  106  of the second bracket component  104  against the holder component  108  to thereby hold or latch the door in a desired predefined locational position (e.g., a specified location) in relation to the door frame when the door is closed. By employing a holder component  108  that comprises a permanent magnet to apply the desired force to latch the door, the system  100  does not have to use external power to maintain latching of the door, which can eliminate power consumption with regard to door latching (e.g., the system  100  can be desirably “green” or eco-friendly). 
     It is to be appreciated and understood though that, while the holder component is often described herein as comprising a magnet, such as a permanent magnet, the subject specification is not so limited, as in accordance with various embodiments of the disclosed subject matter, the holder component can comprise other components or features that can facilitate applying a desired latching force to hold the door in the desired locational position when the door is closed. In accordance with an embodiment, a holder component  108  alternatively can comprise an electromagnet that can receive power to generate an electromagnetic force to be applied to the extended portion  106  to facilitate the door latching. With regard to the door latching, the predefined locational position can be a desired locational position in relation to an operation device (e.g., lock, such as an electromagnetic lock; a sensor; a switch; etc.) (not shown in  FIG. 1 ; e.g., as shown in  FIGS. 3 and 5A ), which can be attached to the first bracket component  102  (e.g., electromagnetic lock, comprising a solenoid actuator and lock pin can be attached to the first bracket component  102 ) and/or second bracket component  104  (e.g., a lock receptacle that is part of or associated with the electromagnetic lock can be attached to the second bracket component  104 ). 
     In accordance with another embodiment, the holder component  108 , when contained on the first bracket component  102 , can comprise a vacuum cup(s) that can apply a desired amount of force to the extended portion  106  of the second bracket component  104  (or conversely, to the surface in the recessed area  110  of the first bracket component  102 , when the holder component  108  is contained on the second bracket component  104 ) (e.g., via the vacuum or suction force generated by applying the vacuum cup to the extended portion  106  of the second bracket component  104 ) to latch or hold the door in the desired locational position. In an aspect, multiple vacuum cups can be employed wherein the amount of latching force applied can be based at least in part on the amount of overlap of the holder component  108  has on the surface (e.g., extended portion  106 ), wherein the amount of overlap can determine the number of vacuum cups that are in contact with the surface when the door is in the closed position (e.g., the more vacuum cups in contact with the surface, the higher the latching force). 
     In still another embodiment, the holder component  108  can be or can comprise a Velcro liner, which can be attached to the first bracket component  102  or the extended portion  106  of the second bracket component  104 , wherein a Velcro receptor can be attached to the other of the first bracket component  102  (e.g., in the recessed area  110 ) or the extended portion  106  of the second bracket component  104 , and the Velcro liner can come in contact with the Velcro receptor when the door is closed such that a desired amount of latching force is created by the Velcro liner being attached to the Velcro receptor to hold the door in the desired locational position. In an aspect, the amount of latching force created by the Velcro liner can be based at least in part on the amount of overlap of the Velcro liner on the Velcro receptor, wherein more overlap can result in a higher latching force and less overlap can result in a lower latching force. The vacuum cup latching feature and the Velcro liner latching feature each can desirably latch the door without consuming or requiring power to generate and apply the desired amount of latching force. 
     In accordance with an aspect, the amount of latching force applied by the holder component  108  to the extended portion  106  of the second bracket component  104  can be controlled and varied (e.g., increased, decreased) based at least in part on the amount of overlap of the extended portion  106  on the surface of the holder component  108  when the door is in the latched position (e.g., when at least a portion of the extended portion  106  is in contact with the surface of the holder component  108 ). As desired, the extended portion  106  can be adjusted or moved in relation to the holder component  108  associated with the first bracket component  102  to facilitate adjusting the amount of overlap and thereby the amount of latching force the holder component  108  applies to the extended portion  106  when the associated door is in the closed position with respect to the door frame. 
     To facilitate adjusting the amount of overlap of the extended portion  106  on the surface of the holder component  108 , the second bracket component  104  can have extended or substantially rectangular or oblong screw guides  112  (e.g., holes wherein a screw(s)  114  can be inserted to attach the second bracket component  104  (and/or an associated component of an operation device) to the door). The second bracket component  104 , including the extended portion  106 , can be moved along the screw guides  112  (e.g., slits) to adjust the amount of overlap the extended portion  106  has with regard to the surface of the holder component  108  when in the closed position until the extended portion  106  has a desired amount of overlap with the holder component  108  to result in the desired amount of latching force when in the closed position, wherein the screws  114  can be tightened to the door to attach the second bracket component  104  to the door at the point along the screw guides  112  that results in the desired amount of overlap of the extended portion  106  on the surface of the holder component  108 . It can be desirable to be able to adjust the amount of latching force because, for example, different doors can have different weights or different door movement resistances, which can affect the amount of latching force that is desired for a particular door (e.g., it can be desirable to have a lower amount of latching force on a lighter door with a light amount of door movement resistance than on a heavier door and/or a door with heavier door movement resistance, for reasons of safety, for example (e.g., a higher latching force can quickly be reduced as the amount of space between the holder component and extended portion increases, which can result in a light door with a light amount of door level resistance suddenly breaking away when the latching force is overcome and the door can then potentially hit and/or injure the user who is opening the door), and/or there can be other factors that make is desirable to adjust the amount of latching force. 
     It is to be appreciated and understood that, while the subject specification generally discloses that the holder component  108  is inserted or attached to a recessed area  110  of the first bracket component  102  and the extended portion  106  is formed of a ferromagnetic material that can be attracted to the force applied by the holder component  108 , the subject specification is not so limited, as, in accordance with another embodiment, the holder component  108  can be attached to the extended portion  106  and a portion of the recessed area  110  can be formed of a ferromagnetic material that can be attracted to the force applied on it by the holder component  108  (e.g., as depicted in  FIG. 6  and described herein). 
     In accordance with various embodiments, the force profile of a latching system can be adjusted or set based at least in part on the shape of the extended portion of the second bracket component. Referring briefly to  FIGS. 2A ,  2 B,  2 C, and  2 D,  FIG. 2A  depicts a portion of a system  200  that can employ a second bracket component having a substantially rectangular extended portion to facilitate door latching in accordance with an embodiment of the disclosed subject matter;  FIG. 2B  depicts a portion of a system  220  that can employ a second bracket component having an extended portion that is partially rounded to facilitate adjusting the force profile to facilitate desired door latching in accordance with another embodiment of the disclosed subject matter;  FIG. 2C  depicts a portion of a system  240  that can employ a second bracket component comprising an extended portion that is rounded on its top end to facilitate adjusting the force profile to facilitate desired door latching in accordance with yet another embodiment of the disclosed subject matter; and  FIG. 2D  depicts a portion of a system  260  that can employ a second bracket component comprising an extended portion that is shaped in the form of a triangle to facilitate adjusting the force profile to facilitate desired door latching in accordance with still another embodiment of the disclosed subject matter. 
     With regard to  FIG. 2A , the portion of the system  200  can include a first bracket component  202  that can be attached to a door frame (not shown in  FIG. 2A ) and can be employed as a door stop and to facilitate latching the door (not shown in  FIG. 2A ) when the door is in the closed position in relation to the door frame. The system  200  can include a second bracket component  204  that can be attached to the door, for example, to facilitate latching of the door when the door is closed in relation to a door frame to which the door can be attached or can otherwise be associated. The second bracket component  204  can have an extended portion  206 , which can be formed of a ferromagnetic material(s) (e.g., a material that can be magnetically attracted to a magnetic force or electromagnetic force), and can be employed to facilitate latching the door when the door is in the closed position, wherein the first bracket component  202  can comprise a holder component  208 , which can include a permanent magnet that can produce a specified amount of magnetic force, and the holder component  208  can be inserted and/or adhered to a recessed area  210  formed in the first bracket component  202  in a region of the first bracket component  202  that can be aligned with the extended portion  206  of the second bracket component  204 . The size of the recessed area  210  can be such that a desired portion of the extended portion  206  can be placed inside the recessed area  210 . The holder component  208  can apply a desired amount of magnetic force to the extended portion  206  to hold the associated door in the closed position when the extended portion  206 , or desired portion thereof, is in contact with the holder component  208 , in accordance with the force profile associated with the extended portion  206 , wherein the force profile can be based at least in part on the shape of the extended portion  206 . 
     In this embodiment, the extended portion  206  can be shaped in the form of a rectangular shape, or a substantially rectangular shape, which can give the extended portion  206  a linear or substantially linear force profile. As a result, when the second bracket component  204  is adjusted in position in relation to the first bracket component  202  by moving the second bracket component  204  along its screw guides  212  the amount of force that can be applied to the extended portion  206  by the holder component  208  when the door is in the closed position can increase linearly or substantially linearly as the amount of overlap of the extended portion  206  on the holder component  208  increases, and can decrease linearly or substantially linearly as the amount of overlap of the extended portion  206  on the holder component  208  decreases. 
       FIG. 2B  illustrates the portion of the system  220 , which can include a first bracket component  222  that can be attached to a door frame (not shown in  FIG. 2B ) and can be employed as a door stop and to facilitate latching the door (not shown in  FIG. 2B ) when the door is in the closed position in relation to the door frame. The system  220  can include a second bracket component  224  that can be attached to the door, for example, to facilitate latching of the door when the door is closed in relation to a door frame to which the door can be attached or can otherwise be associated. The second bracket component  224  can have an extended portion  226 , which can be formed of a ferromagnetic material(s), and can employed to facilitate latching the door when the door is in the closed position, wherein the first bracket component  222  can comprise a holder component  228 , which can include a permanent magnet that can produce a specified amount of magnetic force, and the holder component  228  can be inserted and/or adhered to a recessed area  230  formed in the first bracket component  222  in a region of the first bracket component  222  that can be aligned with the extended portion  226  of the second bracket component  224 . The size of the recessed area  230  can be such that a desired portion of the extended portion  226  can be placed inside the recessed area  230 . The holder component  228  can apply a desired amount of magnetic force to the extended portion  226  to hold the associated door in the closed position when the extended portion  226 , or desired portion thereof, is in contact with the holder component  228  in accordance with the force profile associated with the extended portion  226 . 
     In accordance with this embodiment, the extended portion  226  can be shaped such that it is rounded on one side so as to form a quarter portion of a circle or an oval, which can give the extended portion  226  a specified non-linear force profile. As a result, when the second bracket component  224  is adjusted in position in relation to the first bracket component  222  by moving the second bracket component  224  along its screw guides  232  the amount of force that can be applied to the extended portion  226  by the holder component  228  when the door is in the closed position can increase non-linearly as the amount of overlap of the extended portion  226  on the holder component  228  increases (e.g., the rate of increase in magnetic force can vary (e.g., increase) as the amount of overlap increases), and can decrease non-linearly as the amount of overlap of the extended portion  226  on the holder component  228  decreases (e.g., the rate of decrease in magnetic force can vary (e.g., increase) as the amount of overlap decreases). As a further result, in comparison to the extended portion  206  of  FIG. 2A , the increase in force experienced by (e.g., applied to) the extended portion  226  can be at a relatively slower rate than the increase in force experienced by the extended portion  206  in  FIG. 2A  as the second bracket component is moved to increase overlap of the extended portion  226  on the holder component  228 , and the overall amount of force (e.g., latching force) that can be experienced by the extended portion  226  (e.g., when there is maximum overlap of the extended portion  226  on the holder component  228 ) will be less than the overall amount of force that can be applied to or experienced by the extended portion  206  (e.g., when there is maximum overlap of the extended portion  206  on the holder component  208 ), since the extended portion  206  can have more overlap on the holder component than the extended portion  226 . 
     Turning to  FIG. 2C , illustrated is the portion of system  240 , which can include a first bracket component  242  that can be attached to a door frame (not shown in  FIG. 2C ) and can be employed as a door stop and to facilitate latching the door (not shown in  FIG. 2C ) when the door is in the closed position in relation to the door frame. The system  240  can include a second bracket component  244  that can be attached to the door, for example, to facilitate latching of the door when the door is closed in relation to a door frame to which the door can be attached or can otherwise be associated. The second bracket component  244  can have an extended portion  246 , which can be formed of a ferromagnetic material(s), and can employed to facilitate latching the door when in the closed position, wherein the first bracket component  242  can comprise a holder component  248 , which can include a permanent magnet that can produce a specified amount of magnetic force, and the holder component  248  can be inserted and/or adhered to a recessed area  250  formed in the first bracket component  242  in a region of the first bracket component  242  that can be aligned with the extended portion  246  of the second bracket component  244 . The size of the recessed area  250  can be such that a desired portion of the extended portion  246  can be placed inside the recessed area  250 . The holder component  248  can apply a desired amount of magnetic force to the extended portion  246  to hold the associated door in the closed position when the extended portion  246 , or desired portion thereof, is in contact with the holder component  248 , in accordance with the force profile associated with the extended portion  246 . 
     In this embodiment, the extended portion  246  can be shaped such that it is rounded on both ends of the top side so as to form a semi-circle or semi-oval on the top end of the extended portion  246 , which can give the extended portion  246  a non-linear force profile. As a result, when the second bracket component  244  is adjusted in position in relation to the first bracket component  242  by moving the second bracket component  244  along its screw guides  252  to increase or decrease overlap of the extended portion  246  on the holder component  248 , the amount of force that can be applied to the extended portion  246  by the holder component  248  when the door is in the closed position can increase non-linearly as the amount of overlap of the extended portion  246  on the holder component  228  increases (e.g., the rate of increase in the amount of magnetic force can vary (e.g., increase) as the amount of overlap increases), and can decrease non-linearly as the amount of overlap of the extended portion  246  on the holder component  248  decreases (e.g., the rate of decrease in the amount of magnetic force can vary (e.g., increase) as the amount of overlap decreases), wherein the force profile associated with the extended portion  246  can be different than the force profile associated with the extended portion  226 , even though both force profiles are non-linear. As a further result, in comparison to the extended portion  206  of  FIG. 2A , the increase in force experienced by the extended portion  246  can be at a relatively slower rate than the increase in force experienced by the extended portion  206  in  FIG. 2A  as the second bracket component is moved to increase overlap of the extended portion  246  on the holder component  248  (in  FIG. 2C ), and the overall amount of force (e.g., latching force) that can be experienced by the extended portion  246  (e.g., when there is maximum overlap of the extended portion  246  on the holder component  248 ) will be less than the overall amount of force that can be experienced by the extended portion  206  (e.g., when there is maximum overlap of the extended portion  206  on the holder component  208 ), since the extended portion  206  can have more overlap on the holder component  208  than the amount of overlap the extended portion  246  can have on holder component  248 . 
     Referring to  FIG. 2D , illustrated is the portion of system  260 , which can include a first bracket component  262  that can be attached to a door frame (not shown in  FIG. 2D ) and can be employed as a door stop and to facilitate latching the door (not shown in  FIG. 2D ) when the door is in the closed position in relation to the door frame. The system  260  can include a second bracket component  264  that can be attached to the door, for example, to facilitate latching of the door when the door is closed in relation to a door frame to which the door can be attached or can otherwise be associated. The second bracket component  264  can have an extended portion  266 , which can be formed of a ferromagnetic material(s), and can employed to facilitate latching the door when the door is in the closed position, wherein the first bracket component  262  can comprise a holder component  268 , which can include a permanent magnet that can produce a specified amount of magnetic force, and the holder component  268  can be inserted and/or adhered to a recessed area  270  formed in the first bracket component  262  in a region of the first bracket component  262  that can be aligned with the extended portion  266  of the second bracket component  264 . The size of the recessed area  270  can be such that a desired portion of the extended portion  266  can be placed inside the recessed area  270 . The holder component  268  can apply a desired amount of magnetic force to the extended portion  266  to hold the associated door in the closed position when the extended portion  266 , or desired portion thereof, is in contact with the holder component  268 , in accordance with the force profile associated with the extended portion  266 . 
     In this embodiment, the extended portion  266  can be shaped such that it is in the form a triangle, which can give the extended portion  266  a non-linear force profile, which, for example, can be different from the non-linear force profiles disclosed herein with regard to  FIGS. 2B and 2C . As a result, when the second bracket component  264  is adjusted in position in relation to the first bracket component  262  by moving the second bracket component  264  along its screw guides  272  to increase or decrease overlap of the extended portion  266  on the holder component  268 , the amount of force that can be applied to the extended portion  266  by the holder component  268  when the door is in the closed position can increase non-linearly as the amount of overlap of the extended portion  266  on the holder component  268  increases (e.g., the rate of increase in magnetic force can vary (e.g., increase) as the amount of overlap increases), and can decrease non-linearly as the amount of overlap of the extended portion  266  on the holder component  268  decreases (e.g., the rate of decrease in the amount of magnetic force can vary (e.g., increase) as the amount of overlap decreases). As a further result, in comparison to the extended portion  206  of  FIG. 2A , the increase in force experienced by the extended portion  266  can be at a relatively slower rate than the increase in force experienced by the extended portion  206  in  FIG. 2A  as the second bracket component is moved to increase overlap of the extended portion  266  on the holder component  268  (in  FIG. 2D ), and the overall amount of force (e.g., latching force) that can be experienced by the extended portion  266  (e.g., when there is maximum overlap of the extended portion  266  on the holder component  268 ) will be less than the overall amount of force that can be experienced by the extended portion  206  (e.g., when there is maximum overlap of the extended portion  206  on the holder component  208 ), since the extended portion  206  can have more overlap on the holder component  208  than the amount of overlap the extended portion  266  can have on holder component  268 . 
     Turning to  FIG. 3 , illustrated is a diagram of an example system  300  that can efficiently stop and latch a door in accordance with an embodiment of the disclosed subject matter. In an aspect, the system  300  (e.g., a door latch/door stop system) can comprise a first bracket component  302  (e.g., door frame component) that can be attached to a portion of a door frame  304  at a desired location on the door frame  304 . The system  300  also can include a second bracket component  306  (e.g., door bracket component) that can be attached to a door (e.g., swinging door, sliding door, etc.) (not shown in  FIG. 3  for reason of clarity; e.g., as depicted in  FIG. 5A ) associated with the door frame  304 . In an aspect, the first bracket component  302  and/or second bracket component  306  can be made from a desired material(s), such as a ferromagnetic material(s), which can be attracted to a force (e.g., magnetic force) when a force is applied thereto. The first bracket component  302  can be have a desired shape (e.g., rectangular, square, etc.) and size, wherein, for example, the first bracket component  302  can be large enough in size such that a portion of the first bracket component  302  can be desirably attached to the door frame  304  and a desired portion (e.g., overhanging portion  308 ) of the first bracket component  302  can overhang or extend beyond the door frame  304  and into the doorway so that the first bracket component  302  can be employed, in part, as a door stop and door latching mechanism for the door, which can be associated with (e.g., in the sliding groove of, attached to a side of) the door frame  304 , when the door is being closed. That is, when the door is being closed, the door can come in contact with the overhanging portion  308  of the first bracket component  302  and the first bracket component  302 , including the overhanging portion  308 , can stop the door at that point where the overhang portion  308  is positioned in the doorway. 
     In an aspect, the second bracket component  306  can be shaped (e.g., substantially rectangular or square shaped with regard to the main body of the second bracket component  306 ) and sized, as desired, wherein there can be an extended portion  310  (e.g., tongue, tag), which can have a desired shape and size, that can extend out from the main body of the second bracket component  306 . The extended portion  310  can be employed to facilitate stopping and latching of the associated door, for example, when the extended portion  310  comes in contact with a holder component  312  associated with the first bracket component  302 . 
     The first bracket component  302  can further comprise a desired number of holder components, such as holder components  312  and  314 , which can be attached or adhered to a corresponding number of respective recessed areas  316  and  318 , for example, at or near desired edges of the first bracket component  302 . In an embodiment, a holder component (e.g.,  312 ,  314 ) can be or can include, for example, a permanent magnet that can produce at least a desired amount of force (e.g., magnetic force) to facilitate attracting and holding the extended portion  310  of the second bracket component  306  against the holder component  312  to thereby hold or latch the door in a desired predefined locational position (e.g., a specified location) in relation to the door frame  304  when the door is closed. The predefined locational position can be a desired locational position in relation to an operation device  320  (e.g., lock, such as an electromagnetic lock (as shown in  FIG. 3 ); a sensor; a switch; etc.), which can be attached to the first bracket component  302  (e.g., on the overhanging portion  308  of the first bracket component  302 ), for example, using screws  322  that can be inserted into holes in the first bracket component  302  that can correspond to screw holes (not shown) in the operation device  320 . 
     In an aspect, when the door is a sliding door, the door can be slid (e.g., from right to left with regard to  FIG. 3 ) in a track (not shown) to the closed position wherein at such point the side of the door can be in contact with the door frame  304 , and the extended portion  310  can desirably overlap (e.g., have a desired amount of overlap on the holder component) and be in contact with the holder component  312 , which can apply a desired amount of latching force to the extended portion  310  to latch or hold the door in the closed position. To facilitate enabling the extended portion  310  to more easily engage or enter the recessed area  316 , the edge  324  of the recessed area  316  can have a beveled or chamfered edge that can facilitate guiding the extended portion  310  into the recessed area  316  when the door is being slid to the closed position. The recessed area  318  also can have a beveled or chamfered edge  326 , which can facilitate use of the first bracket component  302  when the door is slid from right to left to close the door, for example, as the first bracket component  302  can be turned 180 degrees from its orientation, as depicted in  FIG. 3 , so that the first bracket component  302  can be attached to the opposite side of the door frame  304 , if the closed position for the door is on the right side of the door frame (right side portion of the door frame  304  is not shown for reasons of brevity and clarity). 
     In an aspect, the first bracket component  302  can be flexible in use, such that it can be used with various different types of doors (e.g., sliding doors, swinging doors, etc.) and various different orientations (e.g., door sliding closed from right to left (in accordance with  FIG. 3 ), door sliding closed from left to right, door sliding down to the closed position, door swinging closed, etc.). The multiple recessed areas, recessed areas  316  and  318 , can be located, for example, at two corners of the first bracket component  302  and recessed such that the extended portion  310  can enter the recessed area when a door swings closed, when a door is slid down to the closed position, when a door is slid closed from right to left (e.g., in accordance with  FIG. 3 ), and/or when a door is slid closed from left to right, in relation to the door frame (e.g.,  304 ). 
     In accordance with one embodiment, the operation device  320  can be a lock (e.g., an electromagnetic lock) that can employ a lock pin (e.g., lock bolt) (not shown) that can be moved between an unlocked position and a locked position to unlock or lock the door, using, for example, a solenoid actuator (not shown) with a solenoid plunger  328  desirably coupled to the lock pin. In an aspect, the second bracket component  306  can have a lock receptacle  330  attached thereto, wherein the lock receptacle  330  can have a hole thereon, and the hole can be aligned with the lock pin while the door is in a desired predefined locational position, so that the lock pin can engage or be inserted in the hole in the lock receptacle  330  to put the lock and associated door in the locked state. The lock can be, for example, a lock (e.g., lock component) such as is more fully described in co-pending U.S. patent application Ser. No. 12/789,989. 
     The second bracket component  306  can comprise screw guides  332  and the second bracket component  306  can be moved or adjusted along the screw guides  332  to facilitate adjusting the amount of overlap of the extended portion  310  on the holder component  312 . When the desired amount of overlap, corresponding to a desired amount of latching force, is achieved, in accordance with the force profile associated with the extended portion  310 , the second bracket component  306  and associated lock receptacle  330  can be firmly attached to the door (not shown) by tightening the screws  334  in corresponding screw holes on the door. 
     In an aspect, when closing and locking the door, the overhanging portion  308  of the first bracket component  302  can act as a door stop for the door, so that the door stops when it comes in contact with the overhanging portion  308 , and the extended portion  310  of the second bracket component  306  comes in contact with the holder component  312 . When the door is stopped in the closed position, the force (e.g., magnetic force) of the holder component  312  can have desired strength (e.g., sufficient strength) to hold or latch the extended portion  310  to thereby latch the door and hold the door closed in the desired predefined locational position. As disclosed herein, the predefined locational position of the door (and thus, the lock receptacle  330 ) can be selected such that, when the door is in that position, the lock pin of the lock component and the hole in the lock receptacle  330  can be desirably aligned in relation to each other so that when the lock component is switched to the locked state, the solenoid plunger  328  can transition the lock pin to engage or be inserted in the hole in the lock receptacle  330  to lock the door with respect to the door frame  304 . 
     It is to be appreciated and understood that, in accordance with various embodiments, an operation device can be or can comprise a lock (e.g., electromagnetic lock), a sensor (e.g., Radio-Frequency Identification (RFID) sensor), a magnetic card reader for receiving authentication credentials (e.g., as contained on a card with a magnetic strip), a keypad or other interface (e.g., touch screen graphical user interface) for receiving authentication credentials (e.g., password, passcode, Personal Identification Number (PIN), etc.), a scanner for scanning or reading information (e.g., authentication credentials) contained in a smart card, a biometric scanner that can scan biometric information associated with a user to facilitate authenticating the user, and/or other interfaces or components, to facilitate controlling operation of the door and access to the associated defined physical area. For example, an operation device can comprise a lock and a magnetic card reader, wherein the lock associated with the door can be unlocked and opened in response to a user swiping a magnetic strip on the user&#39;s card, comprising proper authentication credentials embedded on the magnetic strip, through a reader on the magnetic card reader, and the magnetic card reader granting access to the user. As another example, an operation device can comprise a lock and an RFID sensor, wherein the lock associated with the door can be unlocked and opened in response to the RFID sensor sensing or scanning information (e.g., proper authentication credentials) contained on the user&#39;s RFID card and granting access to the user. 
       FIG. 4  depicts a diagram of an example system  400  that can facilitate intelligently adjusting and selecting a desired amount of force to be applied to an extended portion (e.g., tongue, tag) of a second bracket component (e.g., door bracket component) in accordance with an embodiment of the disclosed subject matter. In an aspect, the system  400  can include a second bracket component  402  that can be attached to a door  404 , using, for example, screws  406 , at a desired position within the screw guides  408 . The screw guides  408  can be oblong shaped holes in the second bracket component  402  that can facilitate adjusting the second bracket component  402  to a desired position, wherein the second bracket component  402  can be fastened to the door  404  in the desired position by inserting and tightening the screws  406  in the screw holes  410  in the door  404  via the screw guides  408  at a position in the screw guides  408  that corresponds with the desired position of the second bracket component  402 . 
     In another aspect, the second bracket component  402  can comprise an extended portion  412  (e.g., tongue, tag), which can run the entire width of the second bracket component  402  (as depicted in  FIG. 4 ) or can span a portion of the width of the second bracket component (e.g., as depicted in  FIG. 1 ). When the door is placed in a closed position in relation to an associated door frame (not shown in  FIG. 4 ), a first bracket component comprising a holder component in a recessed area (not shown in  FIG. 4 ; as depicted, for example, in  FIGS. 1-3 ), which can be attached to the door frame, can be in proximity to the extended portion  412  and the holder component can be in contact with at least a portion of the extended portion  412  and can apply a desired amount of magnetic force to the extended portion  412  to latch or hold the door in the closed position, in accordance with the force profile of the extended portion  412 , wherein the force profile can be based at least in part on the shape of the extended portion  412 . 
     In still another aspect, the system  400  can provide a user with information regarding the amount of latching force that is being applied to the extended portion  412  by the holder component to latch the door, so that the user can intelligently adjust the amount of latching force to a desired level to facilitate desirable (e.g., smooth and safe) latching and unlatching of the door. The second bracket component  402  can include, or can have adhered thereon (e.g., using a suitable adhesive material), a force level guide  414  that can show the respective amounts of latching force that can be applied to the extended portion  412  by the holder component at respective positions of the extended portion  412  of the second bracket component  402  in relation to the holder component associated with the first bracket component. The force level guide  414  can comprise a set of force level lines or grooves that each has a respective force level, such as, for example, force level A, force level B, force level C, . . . , force level F, . . . , associated therewith, wherein the force levels can be in a desired format (e.g., numerical value associated with a desired unit of measure) and a desired level of granularity (e.g., a force level every 5 N or every 10 N; a specified number of different force levels over the available range of force levels; etc.) to facilitate enabling a user to view and understand the amount of latching force being applied for each position of the second bracket component  402 , and thus, the position of the extended portion  412  in relation to the holder component (e.g., amount of overlap of the extended position  412  on the holder component). For example, the first line (e.g., force level A) can indicate 10 N, the second line (e.g., force level B can indicate 20 N, the third line (e.g., force level C) can indicate 30 N, etc. 
     When the second bracket component  402  is adjusted or moved about its screw guides  408  to adjust the amount of overlap of the extended portion  412  in relation to the holder component, the force level guide  414  can indicate the amount of latching force that corresponds with the position of the second bracket component  402  in relation to the holder component and/or associated operation device  416 , or portion thereof (e.g., component, such as a lock receptacle, of the associated operation device). For instance, the user can view the amount of latching force indicated on the force level guide  414  at a particular position of the second bracket component  402  when the portion of the operation device  416  is in a desired position (e.g., predefined locational position) in relation to another portion of the operation device  416  attached to the first bracket component, so the user can be informed as to the amount of latching force and can adjust the position of the second bracket component  414  to thereby adjust the amount of overlap of the extended portion  412  on the holder component, and thereby adjust or control the amount of latching force, to achieve the desired amount of latching force on the extended portion  412  and thereby the associated door. An edge of the portion of the operation device  416  to be attached to the second bracket component  402  can be used with the force level guide  414  to facilitate determining the amount of latching force for a given position (e.g., when the portion of the operation device  416  is in the desired position, the amount of force indicated at the bottom edge of the portion of the operation device  416  can be the amount of force that will be applied is the second bracket component  402  is attached in that position). The respective force levels indicated by the force level guide  414  and the placement of the corresponding force level lines or grooves (e.g., respectively associated with force levels A through F) can be determined based at least in part on the shape of the extended portion  412 , the type of material used to form the extended portion  412 , and the magnetic force of the holder component. In accordance with various embodiments, the force level guide  414  can be formed on the second bracket component  402 , wherein, for example, force level lines and respectively associated force level values can be formed in or on a surface of the second bracket component  402  (e.g., surface facing outward when attached to the door  404 ; or the force level guide  414  can be formed on a force level plate, which can be formed of metal, polymer-based material, paper, or other desired material, and can be attached or adhered to the surface of the second bracket component  402 ). 
       FIG. 5A  depicts a diagram of an example system  500  that can facilitate reducing an amount of impact on an operation device due to closing of a door in accordance with an embodiment of the disclosed subject matter. The system  500  (e.g., a door latch/door stop system) can comprise a first bracket component  502  (e.g., door frame component) that can be attached to a portion of a door frame  504  at a desired location on the door frame  504 . The system  500  also can include a second bracket component  506  (e.g., door bracket component) that can be attached to a door  508  (e.g., swinging door, sliding door, etc.) associated with the door frame  504  (e.g., attached to a portion of the door frame  504 , inserted in a track of the door frame  504 , etc.). In an aspect, the first bracket component  502  and/or second bracket component  506  can be made from a desired material(s), such as a ferromagnetic material(s), which can be attracted to a magnetic force when a force (e.g., magnetic force) is applied thereto. The first bracket component  502  can be have a desired shape (e.g., rectangular, square, etc.) and size, wherein, for example, the first bracket component  502  can be large enough in size such that a portion of the first bracket component  502  can be desirably attached to the door frame  504  and a desired portion (e.g., overhanging portion  510 ) of the first bracket component  502  can overhang or extend beyond the door frame  504  and into the doorway so that the first bracket component  502  can be employed, in part, as a door stop and door latching mechanism for the door  508 , which can be associated with (e.g., in the sliding groove of, attached to a side of) the door frame  504 , when the door  508  is being closed. That is, when the door  508  is being closed, the door  508  can come in contact with the overhanging portion  510  of the first bracket component  502  and the first bracket component  502 , including the overhanging portion  510 , can stop the door  508  at that point. 
     In an aspect, the second bracket component  506  can be shaped (e.g., substantially rectangular or square shaped with regard to the main body of the second bracket component  506 ) and sized, as desired, wherein there can be an extended portion  512  (e.g., tongue, tag), which can be desirably shaped and sized, that can extend out from the main body of the second bracket component  506 . The extended portion  512  can be employed to facilitate stopping and latching of the associated door  508 , for example, when the extended portion  512  comes in contact with a holder component  514 , attached to or inserted in a recessed area  516  of the first bracket component  502 . When the door  508  is closed, the holder component  514  can apply a desired amount of latching force on the extended portion  512  to latch or hold the door in the closed position, which can be a predefined locational position to facilitate operations associated with the door  508  (e.g., locking the door  508 , sensor-related operations, etc.). 
     In still another aspect, the first bracket component  502 , including the overhanging portion  510 , can function as a shock or force absorber for an operation device  518  attached to the overhanging portion  510  of the first bracket component  502 . For instance, the first bracket component  502 , with the overhanging portion  510  that overhangs beyond the door frame  504 , can function as a type of cantilever, wherein the material that forms the first bracket component  502  can have at least some level of elasticity, and when the door  508  impacts and is stopped by the overhanging portion  510  of the first bracket component  502 , the first bracket component  502  can absorb at least a portion of the impact of the door  508 , which can reduce the amount of shock, vibration, or force that is impacted on (e.g., transferred to) the operation device  518 , or portion thereof, that is attached to the first bracket component  502 . 
     Turning briefly to  FIG. 5B  (along with  FIG. 5A ), illustrated is an example system  550  that can employ a shock absorber component, which can further reduce impact of a door on an operation device  518  when the door is closed in accordance with an embodiment of the disclosed subject matter. In this embodiment, when desired, a shock absorber component  552 , which can be fabricated from a desired material(s) (e.g., polymer-based material, such as rubber or plastic; felt; etc.) and can have a desired thickness and shape (e.g., shape that corresponds to the shape of the surface of the overhanging portion  510  with which the shock absorber component  552  will be in contact and/or the shape of the side of the operation device  518  with which the shock absorber component  552  will be in contact), can be inserted between the first bracket component  502  and the operation device  518  to provide further shock or force absorption, beyond the shock absorption provided by the first bracket component  502 , in relation to the operation device  518  to thereby further reduce the amount of shock, vibration, or force impacted on the operation device  518  when the door  508  impacts (e.g., comes in contact with) the overhanging portion  510  of the first bracket component  502  when the door  508  is being stopped by the first bracket component  502  when the door  508  is being latched to the desired predefined locational position for the closed state. 
       FIG. 6  depicts a diagram of an example system  600  that can facilitate monitoring integrity of the door latch/door stop system to facilitate system security and maintenance in accordance with an embodiment of the disclosed subject matter. In an aspect, the system  600  can comprise a first bracket component  602 , second bracket component  604 , extended portion  606 , holder component  608 , recessed area  610 , and screw guides  612  that each can comprise the same or similar features (or a desired portion thereof), or same or similar functionality (or a desired portion thereof), as respective components such as more fully described herein, for example, with regard to system  100 , system  200 , system  300 , system  400 , and system  500 . 
     In accordance with one aspect, the first bracket component  602  can be attached to a door frame (not shown) wherein there can be an overhang portion  614  on the first bracket component  602  that can overhang or extend beyond the door frame and into the doorway formed by or within the door frame. The first bracket component  602  can comprise the recessed area  610  formed in a desired region (e.g., at or near a corner) in the overhang portion  614  of the first bracket component  602 . 
     The second bracket component  604  can be attached to a door (not shown) associated with the door frame. The second bracket component  604  can have an extended portion  606  that can comprise a holder component  608  (e.g., permanent magnet) that can be located (e.g., attached) on the region of the extended portion  606  that faces the recessed area  610  when the door is in the closed position. The extended portion  606 , and correspondingly the holder component  608 , of the second bracket component  604  can have a desired shape and size in order to produce a desired force profile to facilitate desired latching of the door in the closed position by the holder component  608  and the extended portion  606 . Additionally or alternatively, the recessed area  610  can have the shape and size of the region that is formed of a ferromagnetic material formed to a desired shape and size in order to produce a desired force profile. The position of the second bracket component  604  can be adjusted to thereby adjust the amount of overlap of the holder component  608  on the recessed area  610  when the door is in the desired predefined locational position (e.g., desired closed position, wherein the holder component  608  is in contact with and/or is applying the desired amount of latching force to the recessed area  610  to hold the extended portion  606  (and holder component  608 ) against the recessed area  610  and thereby hold the door in the desired closed position). 
     In an embodiment, an operation device(s)  616  (e.g., lock component, RFID sensor, magnetic card reader, biometric scanner, etc.) can be attached to the first bracket component  602  with an associated operation facilitator component  618  (e.g., lock receptacle) attached to the second bracket component  604 . The operation device  616  can perform desired operations (e.g., locking and/or monitoring and controlling access to the defined physical area, controlling access to the defined physical area being secured by the door, etc.) associated with the door and defined physical area. 
     In accordance with an aspect, the system  600  also can comprise a remote operation system  620  that can employ an operation platform  622  to control and/or monitor operations associated with the door (e.g., latching operations, lock operations, sensor operations, etc.) and associated defined physical area, for example. The operation platform  622  can include an operation integrity component  624  that can monitor and sense conditions associated with the first bracket component  602  and second bracket component  604 , the door and associated door frame, and/or the operation device  616  attached to the first bracket component  602  and/or second bracket component  604  to facilitate securing the door and associated defined physical area, as desired, and maintaining desirable operation of the system  600 . 
     In an embodiment, the operation integrity component  624  can be associated with (e.g., electrically connected with and/or communicatively connected with via a wired or wireless communication connection) a sensor component  626  (e.g., magnetic field sensor, which, for example, can be or can include a Reed Switch or Hall-effect sensor) that can be associated with (e.g., connected to, implanted in) the recessed area  610  of the first bracket component  602  and can sense the amount of magnetic field applied to the recessed area  610  by the holder component  608 , or at least can sense a change in state (e.g., magnetized state, unmagnetized state) on the recessed area  610 , on a continuous basis, periodic basis, or in response to a request (e.g., a request from the remote operation system  620 , for example, when such request is received from a user). When the sensor component  626  senses or detects a particular condition (e.g., unlatched extended portion  606 , properly latched extended portion  606 , improperly latched extended portion  606 ), the sensor component  626  can automatically generate and transmit a respective signal (e.g., unlatched signal, proper latch signal, defective latch signal) that can correspond with the sensed condition, wherein the respective signal can be received by the operation integrity component  624  and/or a local component associated with the door (e.g., door status interface (not shown)). The respective signals (e.g., feedback signals) from the sensor component  626  can thereby serve as a Magnetic Bond Sensor (MBS) output as well as a Door Status Switch (DSS) for the door latch formed by the extended portion  606  (with the associated holder component  608 ) and recessed area  610 . 
     For instance, when the door is in the open position in relation to the door frame, the sensor component  626  can sense that the amount of magnetic force applied to or experienced by the recessed area  610  is low (e.g., at or near 0 N) and can transmit an open or unlatched signal that indicates the door is not latched (e.g., the recessed area  610  is not latched to the holder component  608 ) and is thus in an open state to the operation integrity component  624 . When the door is properly closed and latched, the sensor component  626  can sense that the amount of magnetic force applied to or experienced by the recessed area  610  is relatively high (e.g., at or above the predefined minimum threshold latching force level that indicates the recessed area  610  is desirably latched to the holder component  608 ), and the sensor component  626 , can transmit a latched signal (e.g., proper latch signal), which indicates the recessed area  610  is desirably latched to the holder component  608  on the extended portion  606 , to the operation integrity component  624 , and thus, the door is desirably latched in the closed state. As desired, when the door is properly open or closed, respectively, in relation to the door frame, a respective visual indicator or audio indicator indicating proper operation and/or current status of the door (e.g., door latching) also can be provided, for example, by the local door status interface (in response to a corresponding signal from the sensor component  626 ) to let a user near the door know the current status of the door latching. 
     In an aspect, when there is a latching problem between the recessed area  610  and holder component  608  when the door is in the closed position (e.g., door is misaligned in relation to the door frame, the extended portion  606 , and thus the holder component  608 , is misaligned in relation to the recessed area  610 , etc.), the sensor component  626  can sense that the force applied to or experienced by the recessed area  610  from the holder component  608  does not meet the minimum threshold latching force level, which can indicate a defective condition in the latching of the holder component  608  on the recessed area  610 . When the force does not meet the minimum threshold latching force level (but, for example, is above a predefined force level—below which indicates an open or unlatched door), the sensor component  626  can transmit a latch defect signal to the operation integrity component  624 . In response to the latch defect signal, the operation integrity component  624  can generate and transmit a defective latch indicator to the operation device  616  or a desired local interface (e.g., door status interface), wherein the operation device  616  and/or desired local interface can produce a visual or an audio signal to let a user know that the latching between the recessed area  610  and holder component  608  is defective. The operation integrity component  624  also can facilitate generating and providing a latch defect ticket or token, which can be provided to a maintenance system (not shown) or maintenance person to facilitate having the latch defect checked out and rectified. Alternatively or additionally, the latch defect signal can be communicated directly or locally from the sensor component  626  to the door status interface associated with or near the door and the door status interface can broadcast a visual signal (e.g., flashing and/or colored light indicative of latch defect) or an audio signal (e.g., beeping or other sound indicative of a latch defect) to let a user near the door know of the latch defect. 
     The sensor component  626  can be useful, for example, when the operation device  616  is a lock component with a lock pin, wherein the lock component is attached to the first bracket component  602  and the associated operation facilitator component  618 , in this example, a lock receptacle, is attached to the second bracket component  604 , as, when the door latching is operating properly, the sensor component  626  can sense the proper operation of the door latching (e.g., can sense that the magnetic force on the recessed area  610  at least meets the minimum threshold latching force level) and thereby can indicate when the second bracket component  604  and associated lock receptacle are in the desired predefined locational position in relation to the lock pin associated with the first bracket component  602 , so that when the lock pin is moved to the locked position, the lock pin can successfully engage the hole in the lock receptacle to lock the door. 
     Over time and/or for other reasons (e.g., abuse of the door or door latching system), the door may become misaligned, and, as a result, can cause misalignment of the extended portion  606  and/or the holder component  608  in relation to the recessed area  610 , and also can cause misalignment of the lock pin in relation to the hole in the lock receptacle, which can negatively affect operations associated with the door (e.g., door is unable to be locked because the lock pin is not able to engage the hole in the lock receptacle). The misalignment of the extended portion  606  in relation to the holder component  608  can result in a change in the strength of the magnetic field applied by the holder component  608  on the recessed area  610  when the holder component  608  is being latched to the recessed area  610  or an attempt is being made to latch the holder component  608  to the recessed area  610 . The sensor component  626  can detect the force field strength (e.g., magnetic field strength) at the recessed area  610  and can detect that the force on the recessed area  610  does not at least meet the predefined minimum threshold latching force, and can send feedback relating to the detected force field strength (e.g., latch defect signal, amount of force field strength), for example, to the operation integrity component  624 . The operation integrity component  624  can analyze the feedback information from the sensor component  626  and can identify that the force field strength has changed to an undesirable level, and can determine that the door and/or extended portion  606  is misaligned or at least is likely misaligned, and a maintenance or defect ticket can be generated to have a maintenance person check out the door and the door latch/door stop system and correct any defect so that the system operates properly. Further, the operation integrity component  624  can transmit a defective latch indicator to the operation device  616  or a desired local interface (e.g., door status interface) associated therewith or in proximity thereto, wherein the operation device  616  and/or desired local interface can produce a visual signal or an audio signal to let a user know that the latching between the extended portion  606  (with associated holder component  608 ) and recessed area  610  is defective. 
     In another aspect, the remote operation system  620  also can facilitate controlling operations associated with the operation device  616 . For example, when the operation device  616  is a lock component (e.g., employing a bi-stable latching solenoid), the remote operation system  620  can control locking and unlocking of the lock component, and thus, the associated door, to control access to the defined physical area associated with the door. For instance, the remote operation system  620  can monitor power conditions associated with the operation device  616 , and can employ a sensor that can detect when a power off condition is impending with regard to the operation device  616  (e.g., impending loss of power to the operation device  616 , undesirable power fluctuations in power supplied to the operation device  616 ), and can place or transition the operation device  616  into a desired operating state (e.g., locked position) in response to the detected power off condition, and/or can perform other desired operations, as are more fully disclosed in related co-pending U.S. patent application Ser. No. 12/789,989. 
     In an aspect, the remote operation system  620  can employ a processor component  628  that that can work in conjunction with the other components (e.g., operation platform  622 , operation integrity component  624 , etc.) to facilitate performing the various functions of the remote operation system  620 . The processor component  620  can employ one or more processors, microprocessors, or controllers that can process data, such as information relating to received feedback information (e.g., respective signals indicative of door latching status, current state of the door, operation status of an operation device  616 , etc.), information relating to operations of the remote operation system  620 , and/or other information, etc., to facilitate operation of the remote operation system  620 , operation related to latching or securing the door and the associated defined physical area, and operation of system  600  overall; and can control data flow between the remote operation system  620  and other components (e.g., sensor component  626 , door status interface, operation device, etc.) that are or can be associated with the remote operation system  620 . 
     The remote operation system  620  also can include a data store  630  that can store data structures (e.g., user data, metadata); code structure(s) (e.g., modules, objects, classes, procedures) or instructions; information relating to latching conditions between the holder component  608  and the recessed area  610 , operating conditions or operating state of the operation device  616 , predefined operation criteria, predefined minimum threshold latching force, predefined magnetic force level (e.g., at or near 0 N) at or below which indicates an unlatched state, etc., to facilitate controlling operations associated with the remote operation system  620 , etc. In an aspect, the processor component  628  can be functionally coupled (e.g., through a memory bus) to the data store  630  in order to store and retrieve information desired to operate and/or confer functionality, at least in part, to the operation platform  622 , operation integrity component  626 , and/or substantially any other operational aspects of the remote operation system  620 . For instance, in accordance with various embodiments, the systems (e.g., operating environment, sample computing environment) disclosed herein with regard to  FIGS. 12 and 13  can be employed to facilitate operations associated with system  600 . 
     It is to be appreciated and understood that, while, depicted in  FIG. 6  and described herein, the holder component  608  is attached to the extended portion  606  and the sensor component  626  is associated with the recessed area  610 , the subject specification is not so limited, as in accordance with another embodiment, the holder component  608  can be associated with (e.g., attached to) the recessed area  610  (e.g., as depicted in  FIG. 1 ) and the sensor component  626  can be attached to the extended portion  606 , wherein the respective components can function substantially as otherwise described herein. 
       FIGS. 7-11  illustrate methodologies and/or flow diagrams in accordance with the disclosed subject matter. For simplicity of explanation, the methodologies are depicted and described as a series of acts. It is to be understood and appreciated that the subject innovation is not limited by the acts illustrated and/or by the order of acts, for example acts can occur in various orders and/or concurrently, and with other acts not presented and described herein. Furthermore, not all illustrated acts may be required to implement the methodologies in accordance with the disclosed subject matter. In addition, those skilled in the art will understand and appreciate that the methodologies could alternatively be represented as a series of interrelated states via a state diagram or events. Additionally, it should be further appreciated that the methodologies disclosed hereinafter (or at least portions thereof) and throughout this specification are capable of being stored on an article of manufacture to facilitate transporting and transferring such methodologies to computers or other processing devices. The term article of manufacture, as used herein, can encompass a computer program accessible from any computer-readable device, carrier, or media. 
     Now referring to  FIG. 7 , illustrated is an example methodology  700  that can facilitate efficient latching of a door in accordance with various aspects and embodiments of the disclosed subject matter. At  702 , an amount of overlap of an extended portion of a second bracket component on a surface of a holder component associated with a first bracket component can be controlled to obtain a desired amount of latching force between the extended portion and the holder component to hold a door associated with one of the extended portion or the holder component in a predefined locational position in relation to an associated door frame when the door is in the closed position. In an embodiment, the first bracket component can be attached to the door frame and the second bracket component can be attached to a door, wherein the overlap of the extended portion of the second bracket component on a holder component can be adjusted to facilitate correspondingly adjusting the amount of latching force between the extended portion and holder component in accordance with a force profile associated with the extended portion. At  704 , the desired amount of latching force (e.g., magnetic force) can be applied by the holder component to the extended portion to hold the extended portion and the associated door in the predefined locational position when the extended portion is placed in the latched or closed position. 
       FIG. 8  depicts an example methodology  800  that can facilitate stopping and latching of a door in accordance with an aspect of the disclosed subject matter. At  802 , a door can be stopped by, in part, coming in contact with an overhang portion of a first bracket component associated with a door frame when the door is being moved from an open position to a closed position in relation to the door frame. 
     At  804 , a force can be applied to an extended portion of a second bracket component associated with the door to latch the extended portion and associated door in a predefined locational position, wherein the force can be based at least in part on an amount of overlap of the extended portion on a surface of a holder component associated with the first bracket component and the shape of the extended portion. 
     At  806 , a desired operation associated with an operation device, which can be associated with at least one of the first bracket component or the second bracket component, can be performed. For instance, when the operation device is a lock component (e.g., electromagnetic lock comprising a bi-stable latching solenoid), and the extended portion and associated door are in the predefined locational position in relation to the door frame, which can occur when the extended portion is properly latched to the holder component, the lock pin of the lock component, which can be attached to the overhanging portion of the first bracket component, can be placed in a locked position by engaging a hole in a lock receptacle, which can be attached to the second bracket component to place the door in a locked state. 
       FIG. 9  illustrates an example methodology  900  for fabricating a door stop/door latch in accordance with an aspect of the disclosed subject matter. At  902 , a first bracket component can be formed, wherein the first bracket component can comprise at least one recessed area at or near one or more corners of the first bracket component. If and when the first bracket component is attached to, for example, a door frame, the at least one recessed area can be located at or near a corner(s) that will be part of the overhang portion of the first bracket component that will be overhanging or extending outward beyond the door frame and into the doorway. 
     At  904 , at least one holder component can be inserted into the at least one recessed area. The at least one holder component can be, for example, a permanent magnet that can produce and apply at least a desired amount of force to the extended portion to desirably latch and hold the extended portion and thereby the associated door in a closed position (e.g., predefined locational position) in relation to the door frame (e.g., can apply the desired amount of force, or can produce more than the desired amount of force wherein the amount of force ultimately applied to the extended portion can be controlled based at least in part on the shape of the extended portion and the amount of overlap of the extended portion on the holder component). 
     At  906 , the second bracket component can be formed with an extended portion (e.g., tongue, tag) that can have a desired shape and size to facilitate producing a desired force profile. At  908 , the position of the second bracket component can be adjusted in relation to the first bracket component to position the extended portion to have a desired amount of overlap on the holder component to facilitate enabling the holder component to apply the desired amount of latching force on the extended portion to latch or hold the extended portion in a predefined locational position in accordance with the force profile (e.g., force profile that is based at least in part on the shape and size of the extended portion) when the door is being placed in the closed position. At this point, methodology  900  can end and/or proceed to reference point A, wherein, as desired, methodology  1000  can proceed from reference point A, as more fully disclosed herein. 
     Referring to  FIG. 10 , illustrated is an example methodology  1000  that can facilitate construction of a door stop/door latch in accordance with an aspect of the disclosed subject matter. As desired, Methodology  1000  can proceed from reference point A, wherein methodology  900  ended. At  1002 , the first bracket component can be attached to a door frame such that the overhang portion of the first bracket component overhangs or extends out from the door frame into the door way. 
     At  1004 , a first component of an operation device can be attached to the first bracket component. In an aspect, the operation device can be a lock (e.g., electromagnetic lock), and/or sensor (e.g., RFID sensor, magnetic card reader, biometric scanner, movement sensor, etc.), wherein the first component can be, for example, a solenoid actuator (e.g., bi-stable solenoid actuator) when the operation device is a lock or a sensing portion of a sensor. In an embodiment, as desired, a shock absorber component can be inserted in between the overhang portion of the first bracket component and the first component of the operation device to further reduce the impact (e.g., shock, vibration) on the first component of the operation device, beyond the shock or impact absorption that is already provided by the first bracket component, when the door impacts the overhang portion, wherein the overhang portion can act as a door stop, when the door is moved from the open position to the closed position. 
     At  1006 , the second bracket component can be attached to the door at the desired adjusted position for the extended portion of the second bracket component. In an aspect, the position of the extended portion of the second bracket component can be adjusted in relation to the position of the holder component associated with the first bracket component to facilitate achieving a desired amount of latching force in accordance with the force profile associated with the extended portion. 
     At  1008 , a second component of the operation device can be attached to the second bracket component such that the extended portion is in the desired adjusted position in relation to the holder component and the second component is in a desired location in relation to the first component of the operation component attached to the first bracket component. In an aspect, the second component of the operation device can be attached to the second bracket component and the door, for example, by using screws that can be inserted in screw holes in the second component through adjustable screw guides in the second bracket component and into screw holes on the door, wherein the screws can be tightened to attach and hold the second component and second bracket component in the desired adjusted position in relation to each other and the holder component such that a desired amount of latching force can be applied to the extended portion when the door is in the closed position and, when the door is latched, the second component can be in a desired predefined locational position in relation to the first component of the operation device to facilitate proper operation of the operation device (e.g., so the lock pin of the first component (e.g., electromagnetic lock) can engage the hole in the second component (e.g., lock receptacle)). 
     It is to be appreciated and understood that, while the methodologies disclosed herein primarily describe the holder component as being associated with the recessed area of the second bracket component and applying a force to the extended portion to hold the extended portion of the first bracket component during latching, the subject specification is not so limited, as in accordance with various embodiments, the holder component can be associated with (e.g., attached to) the extended portion and can apply a desired force to latch to the recessed area (or another component attached thereto or formed thereon) of the second bracket component (e.g., as described with regard to methodology  1100 ), wherein the respective components can function substantially as otherwise described herein. 
     Turning to  FIG. 11 , depicted is an example methodology  1100  that can monitor and detect operating conditions associated with a door in accordance with an aspect of the disclosed subject matter. At  1102 , operating conditions associated with a door can be monitored. In an aspect, a first bracket component can be attached to a door frame such that an overhang portion of the first bracket component can extend out beyond the door frame and into the doorway to act as a door stop and part of a door latch. The first bracket component can comprise a recessed area (e.g., formed of, or having attached thereto, a ferromagnetic material(s)) to form part of the door stop/door latching system. A second bracket component can be attached to the door, associated with the door frame, and can comprise an extended portion that can have a holder component (e.g., permanent magnet) wherein the extended portion, or at least the holder component, can have a desired size and shape to achieve a desired force profile. The recessed area (or another component formed thereon or attached thereto) can be attracted to the magnetic force produced by the holder component to facilitate latching the door. The second bracket component can be desirably adjusted and attached to the door so that there is a desired amount of overlap of the holder component on the recessed area (or another component attached thereto or formed thereon), and correspondingly, a desired amount of latching force applied by the holder component on the recessed area (or another component attached thereto or formed thereon), when the door is in the closed position, wherein the holder component can be in contact with the recessed area (or another component attached thereto or formed thereon) to latch the door closed. In another aspect, the recessed can have a sensor component (e.g., MBS) that can be attached thereto or inserted therein, and can sense whether the recessed area (or another component attached thereto or formed thereon) is magnetized or not, and/or an amount of latching force (e.g., magnetic force) applied to or experienced by the recessed area (or another component attached thereto or formed thereon) to facilitate determining whether the door is properly latched (e.g., whether the extended portion (with the holder component) is properly latched to the recessed area). 
     At  1104 , a determination can be made regarding whether a latching force is detected. In an aspect, the sensor component can detect whether there is a latching force being applied to the recessed area (or another component attached thereto or formed thereon) by the holder component. For instance, the sensor component can detect whether the recessed area (and/or another component formed thereon or attached thereto) is magnetized or not magnetized. 
     If it is determined that there is no latching force detected, at  1106 , the door latch associated with the door can be identified as being in an open state. If no latching force is detected by the sensor component, the sensor component can transmit an open or unlatched signal to the remote operation system and/or another component), and the remote operation system and/or another component (e.g., local operation system or door status interface) associated with the sensor component can identify the door latch as being in the opened state, that is, can identify the holder component as not being latched to the recessed area. 
     If, at  1104 , it is determined that there is a latching force detected, at  1108 , a determination can be made regarding whether the latching force meets a predefined minimum threshold latching force level. In an aspect, the sensor component can measure or identify the amount of latching force being applied to the recessed area (or another component attached thereto or formed thereon) by the holder component or can provide information that can facilitate measuring or identifying the amount of latching force being applied to the recessed area (or another component attached thereto or formed thereon) by the holder component, wherein the sensor component can transmit a signal or message comprising such information. The amount of latching force can be evaluated in relation to the predefined minimum threshold latching force level (e.g., compared to the predefined minimum threshold latching force level) to determine whether the amount of latching force is at or higher than the predefined minimum threshold latching force level, wherein a latching force amount that is at or greater than the predefined minimum threshold latching force level can indicate that the door latch is properly latched, and/or can thereby indicate that the operation device associated with the door is in the desired predefined locational position for proper operation. 
     If it is determined that the amount of latching force at least meets the predefined minimum threshold latching force level, at  1110 , the door latch can be identified as being properly latched. As desired, the associated operation device can perform any desired operations (e.g., when the operation device is a lock component, the lock pin can be inserted in the hole in the lock receptacle to lock the door). 
     If, at  1108 , it is determined that the amount of latching force is below the predefined minimum threshold latching force level, at  1112 , the door latching can be identified as defective. At  1114 , at least one of a visual indicator or an audio indicator can be presented. In an aspect, a visual indicator or an audio indicator, which indicates that the door latch is defective can be presented locally via an interface(s) associated with the door (e.g., at or near the location of the door and/or associated defined physical area) and/or remotely via an interface(s) associated with the remote operation system. At  1116 , a defect ticket can be generated in response to the identified door latching defect. In an aspect, a defect ticket relating to and identifying the defect in the door latching can be generated and, for example, can be provided to a maintenance person so that the maintenance person can examine and/or repair the door latch (e.g., adjust the position of the extended portion in relation to the holder component, replace a component of the door stop/door latch system, etc.). 
     For purposes of simplicity of explanation, methodologies that can be implemented in accordance with the disclosed subject matter were shown and described as a series of blocks.

To facilitate connection of the disk storage devices  1224  to the system bus  1218 , a removable or non-removable interface is typically used, such as interface  1226 . 
     It is to be appreciated that  FIG. 12  describes software that acts as an intermediary between users and the basic computer resources described in the suitable operating environment  1200 . Such software includes an operating system  1228 . Operating system  1228 , which can be stored on disk storage  1224 , acts to control and allocate resources of the computer system  1212 . System applications  1230  take advantage of the management of resources by operating system  1228  through program modules  1232  and program data  1234  stored either in system memory  1216  or on disk storage  1224 . It is to be appreciated that the claimed subject matter can be implemented with various operating systems or combinations of operating systems. 
     A user enters commands or information into the computer  1212  through input device(s)  1236 .

Interface port(s)  1238  include, for example, a serial port, a parallel port, a game port, and a universal serial bus (USB). Output device(s)  1240  use some of the same type of ports as input device(s)  1236 . Thus, for example, a USB port may be used to provide input to computer  1212 , and to output information from computer  1212  to an output device  1240 . Output adapter  1242  is provided to illustrate that there are some output devices  1240  like monitors, speakers, and printers, among other output devices  1240 , which require special adapters. The output adapters  1242  include, by way of illustration and not limitation, video and sound cards that provide a means of connection between the output device  1240  and the system bus  1218 .

The client(s)  1310  can be hardware and/or software (e.g., threads, processes, computing devices). The system  1300  also includes one or more server(s)  1330 . Thus, system  1300  can correspond to a two-tier client server model or a multi-tier model (e.g., client, middle tier server, data server), amongst other models. The server(s)  1330  can also be hardware and/or software (e.g., threads, processes, computing devices). The servers  1330  can house threads to perform transformations by employing the subject innovation, for example. One possible communication between a client  1310  and a server  1330  may be in the form of a data packet transmitted between two or more computer processes. 
     The system  1300  includes a communication framework  1350  that can be employed to facilitate communications between the client(s)  1310  and the server(s)  1330 .

By way of example, and not limitation, communication media include wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media. Combinations of the any of the above should also be included within the scope of computer-readable media. 
     The aforementioned systems have been described with respect to interaction among several components. It should be appreciated that such systems and components can include those components or sub-components specified therein, some of the specified components or sub-components, and/or additional components. Sub-components can also be implemented as components communicatively coupled to other components rather than included within parent components. Additionally, it should be noted that one or more components could be combined into a single component providing aggregate functionality. The components could also interact with one or more other components not specifically described herein but known by those of skill in the art. 
     It is to be appreciated and understood that components (e.g., first bracket component, second bracket component, extended portion, holder component, operation device, etc.), as described with regard to a particular system or methodology, can include the same or similar functionality as respective components (e.g., respectively named components) as described with regard to other systems or methodologies disclosed herein. 
     Furthermore, the disclosed subject matter can be implemented as a method, apparatus, or article of manufacture using standard programming and/or engineering techniques to produce software, firmware, hardware, or any combination thereof to control a computer to implement the disclosed subject matter. The term “article of manufacture” as used herein is intended to encompass a computer program accessible from any computer-readable device, carrier, or media. For example, computer readable media can include but are not limited to magnetic storage devices (e.g., hard disk, floppy disk, magnetic strips . . . ), optical disks (e.g., compact disk (CD), digital versatile disk (DVD) . . . ), smart cards, and flash memory devices (e.g., card, stick, key drive . . . ). Additionally it should be appreciated that a carrier wave can be employed to carry computer-readable electronic data such as those used in transmitting and receiving electronic mail or in accessing a network such as the Internet or a local area network (LAN). Of course, those skilled in the art will recognize many modifications can be made to this configuration without departing from the scope or spirit of the disclosed subject matter. 
     Some portions of the detailed description have been presented in terms of algorithms and/or symbolic representations of operations on data bits within a computer memory. These algorithmic descriptions and/or representations are the means employed by those cognizant in the art to most effectively convey the substance of their work to others equally skilled. An algorithm is here, generally, conceived to be a self-consistent sequence of acts leading to a desired result. The acts are those requiring physical manipulations of physical quantities. Typically, though not necessarily, these quantities take the form of electrical and/or magnetic signals capable of being stored, transferred, combined, compared, and/or otherwise manipulated. 
     It has proven convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like. It should be borne in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. Unless specifically stated otherwise as apparent from the foregoing discussion, it is appreciated that throughout the disclosed subject matter, discussions utilizing terms such as processing, computing, calculating, determining, and/or displaying, and the like, refer to the action and processes of computer systems, and/or similar consumer and/or industrial electronic devices and/or machines, that manipulate and/or transform data represented as physical (electrical and/or electronic) quantities within the computer&#39;s and/or machine&#39;s registers and memories into other data similarly represented as physical quantities within the machine and/or computer system memories or registers or other such information storage, transmission and/or display devices. 
     In the subject specification, terms such as “data store,” “storage,” and substantially any other information storage component relevant to operation and functionality of a component, refer to “memory components,” or entities embodied in a “memory” or components comprising the memory. For example, information relevant to operation of various components described in the disclosed subject matter, and that can be stored in a memory, can comprise, but is not limited to comprising, information relating to operation of the lock component, programming information, information relating to authentication and authorization to access the lock component, etc. It will be appreciated that the memory components described herein can be either volatile memory or nonvolatile memory, or can include both volatile and nonvolatile memory. By way of illustration, and not limitation, nonvolatile memory can include read only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable ROM (EEPROM), phase change memory (PCM), flash memory, or nonvolatile RAM (e.g., ferroelectric RAM (FeRAM). Volatile memory can include random access memory (RAM), which acts as external cache memory. By way of illustration and not limitation, RAM is available in many forms such as synchronous RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), enhanced SDRAM (ESDRAM), Synchlink DRAM (SLDRAM), and direct Rambus RAM (DRRAM). Additionally, the disclosed memory components of systems or methods herein are intended to comprise, without being limited to comprising, these and any other suitable types of memory. 
     Further, as used in this application, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or”. That is, unless specified otherwise, or clear from context, “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then “X employs A or B” is satisfied under any of the foregoing instances. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form. 
     What has been described above includes examples of the subject specification. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the subject specification, but one of ordinary skill in the art can recognize that many further combinations and permutations of the subject specification are possible. Accordingly, the subject specification is intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims. Furthermore, to the extent that the term “includes” is used in either the detailed description or the claims, such term is intended to be inclusive in a manner similar to the term “comprising” as “comprising” is interpreted when employed as a transitional word in a claim.
