Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of priority under 35 U.S.C. § 120 as a continuation of U.S. application Ser. No. 16/122,029, filed Sep. 5, 2018 and claims the benefit of and priority under 35 U.S.C. § 119(e) to U.S. provisional patent application Nos. 62/555,172, filed Sep. 7, 2017 and 62/570,225, filed Oct. 10, 2017, the entirety of which is hereby incorporated by reference. 
    
    
     BACKGROUND OF THE PRESENT DISCLOSURE 
     As a general proposition, light in the ultraviolet region of the electromagnetic spectrum has proven particularly useful in killing bacteria in an array of professional and industrial environments. Moreover, apparatus for sterilizing garments with ultraviolet (UV) light have been conceived and manufactured. Among the extant apparatus is a locker-type enclosure, the interior of which includes one or more UV-light sources and which can accommodate the hanging of garment for selective sterilization by UV light emitted by the one or more light sources. 
     Against the backdrop of the previous development of UV-light sterilization apparatus, improvements have been made incrementally. Even so, while existing UV-emitting enclosures are capable of sterilizing external garment surfaces within “line of sight” of the UV-emitting sources disposed along the enclosure&#39;s interior, such a configuration is insufficient for sterilizing the inside surfaces of garments such as medical and lab coats and shirts. Areas of particular concern that go unsterilized by current UV-sterilization systems are sleeve and pocket interiors. When a garment is hanged in the normal manner, the sleeves hang down to the sides of the portion of the garment designed for the torso and the UV-light simply cannot access the sleeve interiors or the portions of the sleeves and torso portion that are adjacent one another. 
     One “work-around” the partially addresses the shortcomings of previous UV-sterilization enclosures is to hang a garment on a hanger within the enclosure in the normal manner and send it through a first sterilization cycle. The first cycle will sterilize most of the garment exterior, with the exception of the aforementioned portions of the sleeves and torso portion that hand adjacent one another. Subsequent to such a first cycle, a user can remove the garment from the enclosure and turn it inside out, hang it back on a hanger, and send through a second sterilization cycle, which second cycle will sterilize most of the interior surfaces of the garment. 
     Two disadvantages of the described work-around are (i) it is a two-stage process requiring more than twice the time required to run a single sterilization cycle and (ii) while it results in a substantially greater percentage of a garment&#39;s surface being sterilized than a first sterilization cycle alone, it still does not sterilize all—or even nearly all—of the garment surfaces. Left of sterilized by the two-stage work-around are, again, (i) portions of the sleeves and torso portion that hand adjacent one another, on both the interior and exterior surfaces of the garment and (ii) pocket interiors, pocket interiors representing a garment region that hosts high concentrations of bacteria. 
     SUMMARY OF THE PRESENT DISCLOSURE 
     Accordingly, a need exists for a sterilization system that combines elements cooperatively configured to holistically sterilize a garment in a single stage using ultraviolet light. 
     In each of various illustrative embodiments, a systemic approach to single-stage garment sterilization is achieved by uniquely configured, mutually cooperative elements. More specifically, an illustrative configuration involves three major elements: (i) a garment enclosure, (ii) a uniquely-configured garment hanger, and (iii) a set of “orbs,” each of which orbs is configured to selectively emit UV light, and is alternatively referred to as a UV-emitting orb. Each of the three major elements is described in detail below. 
     In accordance with one implementation, a garment enclosure that allows one-step sterilization using UV light is disclosed. The garment enclosure includes a housing, wherein the housing further includes a plurality of housing walls defining an interior garment cavity configured to selectively receive and temporarily house at least one garment to be sterilized; a door that is selectively openable and closable for introduction and removal of garments from the internal garment cavity; and at least three UV-emitter sets. The door may be configured to be closable to prevent leakage to the housing exterior of UV light during sterilization cycles. The housing may resemble a shape of, e.g., a cabinet, a locker, a closet, an armoire, or any other enclosure. 
     Each housing wall may include a housing-wall inside and outside surface defining, respectively, a portion of the overall housing interior and exterior. The housing-wall inside faces an interior of the housing wall and a surface, wherein surface may include a first UV-emitter set. The first UV-emitter set may include a UV-emitter configured to selectively emit light within the ultraviolet range of the electromagnetic spectrum when energized by electrical current. The UV-emitter is hereinafter alternatively referred to as a UV-emitter or UV-emitting element. In another embodiment of the present disclosure, a housing including only a single UV-emitter is within the scope of the overall concept, and it is envisioned that the housing interior have disposed along more than one inside wall surface a plurality of UV-emitters configured and mutually arranged to selectively bombard the housing interior with UV light. 
     Additionally, in order to facilitate the thorough and even distribution of UV light throughout the housing interior, the housing-wall inside surfaces may be configured to be reflective of UV light. In one embodiment of the present disclosure, UV reflectivity is achieved by fabricating the interior of the housing walls from a reflective material. The reflective materials may include, e.g., aluminum, polished aluminum, glass, hydroponics, any material with a greater than 75% reflectivity of UV light, or any combinations thereof. In another embodiment of the present disclosure, the housing-wall inside surfaces may be coated in a UV-reflective coating. The UV-reflective coating may include aluminum, glass, hydroponics, any material with a greater than 75% reflectivity of UV light, or any combinations thereof. In yet another embodiment of the present disclosure, reflective elements may be fastened to the housing-wall inside surfaces by any of various fastening element including, e.g., rivets, threaded fasteners, and an adhesive such as glue or epoxy, or any combinations thereof. 
     While it is envisioned that various embodiments include a garment enclosure preassembled with the specific sterilization purposes in mind, and therefore incorporating, at the time of manufacture, the UV-emitter and reflective surfaces along the housing-wall inside surfaces, a retrofitting option is also disclosed herein. More specifically, according to an aspect of the present disclosure, a retrofitting kit includes at least one sterilization panel configured for installation into an existing garment enclosure (e.g., locker, cabinet, armoire, and the like). The sterilization panel has depending therefrom, or otherwise incorporated therein, at least one UV emitters. Each panel of the retrofitting kit is configured for mounting on an inner surface (e.g., inside housing wall) of the pre-existing garment enclosure. In another embodiment of the present disclosure, the retrofitted garment enclosure would then function in essentially the same manner as a garment enclosure with UV-emitter that is fabricated as a single unit from inception in accordance with the principles of the present invention. 
     Whether used in conjunction with a garment enclosure fabricated from inception to emit UV light, or in conjunction with a retrofitted garment enclosure, an overall UV-sterilization system configured in accordance with the present invention further includes a uniquely configured garment hanger. In one embodiment, the garment hanger is configured for hanging a garment includes at least a torso portion with a torso-portion interior, an exterior surfaces, a left and a right sleeve portions depending from the torso portion, sleeve-portion interior, and exterior surfaces. The garment hanger further includes a hook portion by which the hanger may be hung within the garment enclosure. Depending from the hook portion is a garment-support frame, which includes left-side and right side hanger arms corresponding to, and configured to at least partially coextend with, respectively, the left and right sleeve portions of the garment. In order to facilitate UV-sterilization of the torso-portion and sleeve-portion interior surfaces, a second UV-emitter set includes at least one electrically energizable UV-emitter that is carried by the garment support frame of various garment hanger embodiments. 
     In an embodiment of the present disclosure, the garment enclosure includes a hanger station configured to receive hook portion of the garment hanger. The hook portion may be hanged on the hanger station. The hanger station may include a pole. The presence of the hook portion upon the hanger station defines a detectable registration condition. That is, in such an embodiment, when the hook portion is hung as intended and properly seated upon the hanger station, the garment hanger is regarded as “in registration” with the hanger station. In at least one embodiment, the registration condition of the hanger facilitates selective energizing of the second UV-emitter set from the exterior of the garment housing. This may be facilitated by the proper seating of the hook portion upon the hanger station establishing electrical connectivity between the second UV-emitter set of the garment hanger and a power source that, for example, provides electrical power to the garment enclosure (e.g., to the first UV-emitter set disposed within the housing interior of the garment enclosure). The power source may include, e.g., a battery, an electricity outlet, and the like. 
     In addition, or as an alternative, to the registration condition enabling electrical energizing of a second UV-emitter set, if present, the registration condition may be tied to the overall functionality of the UV-sterilization system. That is, for example, the system as a whole may not be energizable in some implementations if at least one garment hanger is not detected as “in registration” with at least one hanger station within the garment enclosure. 
     As described, one of the problems in association with previous UV-sterilization systems is that, when a sleeved garment is hung on a hanger of substantially standard configuration, parts of the torso-portion and sleeve-portion exterior surfaces hang directly adjacent and in contact with one another, thereby preventing impingement thereon by sterilizing ultraviolet light. Various embodiments of the present UV-sterilization system include garment hangers uniquely configured to address this issue. 
     According to one hanger configuration, each of the left-side and right-side hanger arms comprises a shoulder-support portion and a corresponding sleeve-support portion configured to support, respectively, a shoulder and sleeve portion of a sleeved garment. As one would expect, the sleeve support portion is more distant from the hook portion than is the corresponding shoulder-support portion. Each of the left-side and right-side hanger arms further includes an elbow defining an obtuse angle between the shoulder-support and sleeve-support portions thereof. The elbow is such that the sleeve portion of a garment hanging on the hanger protrudes one of (i) forwardly and (ii) backwardly from the torso portion of the garment in order to maximize the surface area along each sleeve-portion exterior surface that is supported out of contact with the torso-portion exterior surface adjacent thereto. By this configuration, impingement of ultraviolet light upon the otherwise-obstructed adjacent exterior surfaces is facilitated. 
     Although previously specified was a garment hanger having a garment support frame carrying a second UV-emitter set with as few as a single UV-emitter, another version prescribes that the second UV-emitter set include at least one UV-emitter disposed along each of the left-side and right-side hanger arms. A still-additional version calls for the second UV-emitter set to include a plurality of UV-emitters disposed along each of the left-side and right-side hanger arms. In general, the greater the number of UV-emitter included within the second UV-emitter set, the more thorough and efficient will be the sterilization of torso-portion and sleeve-portion interior surfaces of a sleeved garment undergoing sterilization. Additionally, a variation of the hanger is configured such that least the shoulder-support and sleeve-support portions of each hanger arm comprises a material that is translucent relative to ultraviolet light. It will be readily appreciated that translucency of the garment support frame facilitates maximizing the surface area of the torso-portion and sleeve-portion interior surfaces that are impinged upon by ultraviolet light emitted from UV-emitters of the second UV-emitter set. 
     As garment pockets host a particularly high concentration of bacteria, variations of the UV-sterilization include pocket-sterilizing orbs. An illustrative pocket-sterilizing orb includes a bulbous orb housing defining an interior orb cavity containing a third UV-emitter set including at least one electrically energizable UV-emitter. The orb housing is configured for insertion into a pocket of a garment to be sterilized. Moreover, the orb housing comprising a material that is translucent relative to ultraviolet light in order to facilitate maximization of the surface area of the pocket interior surface that is impinged upon by ultraviolet light emitted from the at least one UV-emitter of the third UV-emitter set. 
     It is generally envisioned that a pocket-sterilizing orb will be inserted into a garment pocket of a garment to be sterilized within the garment enclosure in order to sterilize the pocket interior contemporaneously the sterilization of other garment portions by other elements of the UV-sterilization system. Accordingly, in at least one embodiment, the third UV-emitter set is selectively energizable through an electrically-conductive orb tether having an orb-tether first end electrically connected to the third UV-emitter set and an orb-tether second end that is electrically connectable to an orb-energizing electrical connection situated on at least one of (i) the garment hanger and (ii) one of the housing-wall inside surfaces. In this way, if the first, second, and third UV-emitter sets are electrically linked to a single energizing circuit, they can be activated and deactivated simultaneously. 
     Representative embodiments are more completely described and depicted in the following detailed description and the accompanying drawings.

Moreover, the separation of various system components in the implementations described above should not be understood as requiring such separation in all implementations, and it should be understood that the described program components and systems can generally be integrated together in a single software product or packaged into multiple software products. 
     Referring to  FIGS. 1-5  concurrently, components of an illustrative UV-sterilization system are shown and described. As indicated in the summary, an illustrative UV-sterilization system includes up to three main cooperating elements, each of which may incorporate UV-emitting elements: (i) a garment enclosure  100 , (ii) a garment hanger  200 , and (iii) a set of pocket-sterilizing orbs  300 . Each of these three elements is the subject of detailed discussion below and in conjunction with referenced drawings. 
     Referring to  FIGS. 1 and 2  concurrently, a garment enclosure  100  includes a housing  110  and a door  160  attached to the housing. The housing  110  may include a generally rectangular configuration resembling a standard cabinet, closet, or locker. The housing  110  includes a plurality of housing walls  120 , each of which further includes a housing-wall inside surface  122  and a housing-wall outside surface  124 . Collectively, the housing-wall inside and outside surfaces  122  and  124  define, respectively, an interior garment cavity  130  and the overall housing exterior  140 . 
     The garment cavity  130  is configured to selectively receive and contain at least one garment to be sterilized. Access to the interior garment cavity  130  is facilitated through a door  160  that is selectively openable, as in  FIG. 2 , for the introduction into and removal of garments from the garment cavity  130 , and closable, as shown in, e.g.,  FIG. 1 , to prevent leakage to the housing exterior of UV light during sterilization cycles. 
     Disposed on at least one housing-wall inside surface  122  is a first UV-emitter set  180 , which includes at least one UV-emitter  185 , configured to selectively emit light within the UV range of the electromagnetic spectrum when energized by an electrical current. In one embodiment of the present disclosure, the light emitted may include, e.g., x-rays, gamma rays, infrared, and any other electromagnetic ray. 
     As shown in, e.g.,  FIGS. 1-2 , it is advantageous for the housing interior (the garment cavity  130 ) to have disposed along the interior at least one housing-wall inside surface  UVL  a plurality of UV-emitters  185  configured and mutually arranged to thoroughly bombard the garment cavity  130  with UV light. Moreover, as shown in  FIG. 2 , for example, thorough and even distribution of UV light is facilitated by rendering the at least one housing-wall inside surfaces  122  reflective of UV light. In an embodiment of the present disclosure, the housing-wall inside surfaces  122  may include a UV-reflective lining  122   UVL . 
     The UV-sterilization system incorporate a specially-configured garment hanger  200  that works in conjunction with the garment enclosure  100  with the goal of maximizing the surface area of garment that is impinged upon by sterilizing ultraviolet light. Moreover, as shown in, e.g.,  FIGS. 3 and 4 , the configuration and use of the illustrative garment hanger  200  is shown relative to the hanging of a garment  500  including at least a torso portion  510  with a torso-portion interior surface  512  and a torso-portion exterior surface  514 , respectively, and left and right sleeve portions  520   L  and  520   R , respectively, depending from the torso portion  510 , the sleeve portions  520   L  and  520   R  including sleeve-portion interior and exterior surfaces  530  and  540 , respectively. Furthermore, in order to demonstrate additional features associated with various versions of the UV-sterilization system, the garment  500  may include a pocket  550 . 
     An illustrative garment hanger  200  may include a hook portion  210  by which the garment hanger  200  may be hung within the garment enclosure  100 . Depending from the hook portion  210  is a garment-support frame  215  which further includes a left-side hanger arm  220   L  and a right-side hanger arm  220   R  corresponding to, and configured to at least partially coextend with and support, respectively, the left sleeve portion  520   L  and the right sleeve portions  520   R  of the garment  500 , as shown in  FIG. 4 . The left-side and right-side hanger arms  220   L  and  220   R  comprise, respectively, shoulder-support portions  222   L  and  222   R  and corresponding sleeve-support portions  224   L  and  224   R  configured to support, respectively, left and right shoulder portions  522   L  and  522   R  and the left and right sleeve portions  520   L  and  520   R  of the garment  500 . The garment-support frame  215  may further include a hook portion  210 , upper side  217  and an underside  216 . 
     In order to promote impingement of ultraviolet light upon maximum surface areas of the torso-portion exterior surfaces  514  and the sleeve-portion exterior surfaces  540 , each of the left-side hanger arm  220   L  and right-side hanger arm  220   R  further includes an elbow  225  defining a “sharp” or “abrupt” elbow angle θ between the corresponding shoulder-support portions  222   L  and  222   R  and sleeve-support portions  224   L  and  224   R  thereof. The elbows  225  are such that the left and right sleeve portions  520   L  and  520   R  of a garment  500  hanging on the garment hanger  200  protrude one of (i) forwardly and (ii) backwardly from the torso portion  510  of the garment  500 . Of course, whether the sleeve portions  520   L  and  520   R  extend forwardly or backwardly of the torso portion  510  is a function of which way the garment  500  is draped over the garment hanger  200 . In the applicable figures, the sleeve portions  520   L  and  520   R  extend forwardly of the torso portion  510 . It will be appreciated that the sharply-bent configuration of each of the hanger arms  220   L  and  220   R  helps maximize the surface area along each sleeve-portion exterior surface  540  that is supported out of contact with the torso-portion exterior surface  514  adjacent thereto. By this configuration, impingement of ultraviolet light emitted from UV-emitters  185  of the first UV-emitter set  180  upon the otherwise-obstructed adjacent exterior surfaces  514  and  540  is facilitated. 
     In order to facilitate UV-sterilization of the torso-portion interior surface  512  and sleeve-portion interior surface  530 , a garment hanger  200  is configured to incorporate a second UV-emitter set  280 . The second UV-emitter set  280  includes at least one electrically energizable UV-emitter  285 . In the view of  FIG. 5 , UV-emitters  285  of the second UV-emitter set  280  may be carried by or attached to the garment-support frame  215 . The UV-emitters  285  may be distributed along an underside  216  of an opaque garment-support frame  215 . However, it is to be understood that this arrangement, as well as the opacity of the garment-support frame  215  are illustrative and non-limiting in nature. For instance, in another embodiment of the present disclosure, the garment-support frame  215  may be constructed, at least in part or in its entirety, from a material that is translucent with respect to ultraviolet light in order to promote the impingement of ultraviolet light upon the torso-portion interior surface  512  and sleeve-portion interior surfaces  530  resting upon the upper side  217  of the garment-support frame  215 . Returning to the opaque version depicted in, e.g.,  FIG. 5 , the underside  216  of the opaque garment-support frame  215  may be lined with a UV-reflective lining  216   UVL . The UV-reflective lining  216   UVL  reflects ultraviolet light emitted from UV-emitters  285  of the second UV-emitter set  280  downwardly and into the lower portions of the torso-portion interior surface  512  and sleeve-portion interior surface  530 . It should, of course, be noted that another version of the garment hanger  200  within the scope and contemplation of the invention may include a garment-support frame  215  that is both translucent to ultraviolet light and includes a UV-reflective lining  216   UVL . 
     The second UV-emitter set  280  carried by the garment hanger  200  requires a source of electrical power available to selectively energize its constituent UV-emitters  285 . To this end, means of supplying electrical current to the second UV-emitter set  280  are discussed with principal reference to, e.g.,  FIGS. 3 and 5 . As seen in  FIG. 3 , a hanger station  170  is provided within the garment enclosure  100  and configured to receive for hanging the hook portion  210  of the garment hanger  200 . The presence of the hook portion  210  upon the hanger station  170  defines a detectable registration condition. In the version of the hanger station  170  and garment hanger  200  depicted, the garment hanger  200  being “in registration” with the hanger station  170  enables or triggers selective energizing of the second UV-emitter set  280 . More specifically, the hanger station  170  may be provided with station electrical contacts  172   e  and the hook portion  210  of the garment hanger  200  is provided with hanger electrical contacts  212   e . When the hook portion  210  is properly seated upon the hanger station  170 , the hanger electrical contacts  212   e  are in electrical contact with the station electrical contacts  172   e , thereby establishing electrical connectivity between the second UV-emitter set  280  and a power source (not shown) that, for example, provides electrical power to the garment enclosure  100  as whole (e.g., to the first UV-emitter set  180  disposed within the housing interior of the garment enclosure  100 ). 
     The UV-sterilization system further includes pocket-sterilizing orbs  300 . As shown in, e.g.,  FIG. 6 , the pocket-sterilizing orb  300  may include a bulbous orb housing  310  defining an interior orb cavity  315 , a third UV-emitter set  380  placed within the interior orb cavity  315  and containing at least one electrically energizable UV-emitter  385 , and an orb-tether first end  392 , an orb-tether second end  394 , and an electrically-conductive orb tether  390 , wherein the orb-tether first end  392  is connected to the third UV-emitter set  380 , wherein the orb-tether first end  392  is connected to the orb-tether second end  394  via the electrically-conductive orb tether  390 . The orb housing  310  may be configured for insertion into a pocket  550  of a garment  500  to be sterilized. Additionally, the orb housing  310  is fabricated from a material that is translucent relative to the UV light in order to facilitate maximization of the surface area of the pocket interior surface that is impinged upon by ultraviolet light emitted from the at least one UV-emitter  385  of the third UV-emitter set  380 . 
     The pocket-sterilizing orb may be inserted into a garment pocket  550  of a garment  500  to be sterilized within the garment enclosure  100  in order to sterilize the pocket interior surface while simultaneously sterilizing other garment portions by other elements of the UV-sterilization system. Accordingly, in at least one version, the third UV-emitter set  380  is selectively energizable through the electrically-conductive orb tether  390  having the orb-tether first end  392  electrically connected to the third UV-emitter set  380  and the orb-tether second end  394  that is electrically connectable to an orb-energizing electrical connection situated on at least one of (i) the garment hanger  200  and (ii) one of the housing-wall inside surfaces (electrical connection not shown in this provisional, but readily comprehensible and therefore adequately disclosed). In this way, if the first, second, and third UV-emitter sets  180 ,  280 , and  380 , respectively, are electrically linked to a single energizing circuit, they can be activated and deactivated simultaneously. In an embodiment, this activation and deactivation may be configured to be carried out by a manual input or instruction by a user, or automatically upon detection of the presence (or absence) of the garment  500  inside the garment enclosure  100 . 
     In order to encourage and monitor usage, particularly in institutional settings, each of various embodiments of a UV-sterilization system is cooperatively associated with a method and system for remotely status-monitoring UV-sterilization garment enclosures  100 .  FIG. 7  illustrates an example of an implementation and associated architecture for status-monitoring a UV-sterilization system as disclosed herein. For ease of reference and discussion, implementations of the monitoring system and associated architecture are hereinafter referred to as “UV-sterilization monitoring system  700 .” 
     The UV-sterilization monitoring system  700  may include data-processing system  710 , garment enclosure banks  100 B containing on-site machine-to-human interface  730 , at least one remote machine-to-human interface  750 , and an individual-user machine-to-human interface  750   IND , wherein each of the aforementioned elements may be connected to each other via communications network. 
     The data processing system  710  may include a computer  712 , a computer memory  720 , and a locker-user data file  722 , wherein the computer  712 , the computer memory  720 , and the locker-user data file  722  are connected via communications network. Each of the computer  712 , the computer memory  720 , and the locker-user data file  722  may include a server and a database, wherein each of the server and the database may further include a machine readable medium that is configured to carry out the processes for sanitizing a garment as disclosed herein. Although the UV-sterilization monitoring system  700  may be implemented in association with as few as one UV-sterilization garment enclosure  100 , such a system  700  may also be associated or connected with a plurality or “bank” of garment enclosures  100  via communications network. Accordingly, the UV-sterilization monitoring system  700  provides an example of a garment enclosure bank  100 B illustratively including more than one garment enclosures  100 , 
     According to an embodiment of the present disclosure, there is associated with each garment enclosure  100  an on-site machine-to-human interface  730 . In another embodiment, each garment enclosure  100  includes a dedicated machine-to-human interface  730 , while, in another version, a single machine-to-human interface  730  is communicatively linked to each of several garment enclosures  100 . For purposes of efficiency and brevity in explanation, both options are shown in coexistence in the schematic of  FIG. 7 . In either or both cases, an on-site machine-to-human interface  730  may be configured as a keypad and/or touchscreen with an associated display. The on-site machine-to-human interface  730  may further include a kiosk or another computer that is capable of interacting with the user via, e.g., receiving an input, relaying information, and the like. 
     In each of various implementations, the data processing system  710  may be communicatively linked (via, e.g., communications network) and associated with is the at least one remote machine-to-human interface  750 . In a first instance, an individual-user machine-to-human interface  750   IND  enables a human individual user(s) to communicate remotely with any of the components of the UV-sterilization monitoring system  700  for any of various purposes. For instance, an individual user who has placed a garment  500  in a garment enclosure  100  for sterilization may wish to check on the status of a cleaning cycle so that he or she knows when the garment  500  is clean. For this purpose, it is also contemplated that the UV-sterilization monitoring system  700  could send a notification to a user&#39;s individual-user machine-to-human interface  750   IND  when a cleaning cycle is complete. The user&#39;s individual-user machine-to-human interface  750   IND  may include, e.g., a computer. Alternatively, a user seeking an available garment enclosure  100  in which to place a garment  500  requiring cleaning could consult the UV-sterilization monitoring system  700  through his or her individual-user machine-to-human interface  750   IND  to locate a nearest available garment enclosure  100 . 
     Alternatively (or additionally) to associated individual-user machine-to-human interfaces  750   IND , the UV-sterilization monitoring system  700  may include at least one institutional-user machine-to-human interface  750   INST  that is communicatively linked (via, e.g., communications network) and associated with the data processing system  710 . In this context, “institutional-user” may include a supervisor, a system operator, an authorized user, or an organization having an interest in monitoring use of garment enclosures  100  associated with the UV-sterilization monitoring system  700  by individuals. Such institutional-user may include, by way of non-limiting example, hospitals, nursing homes, restaurants, hotels, department stores wear clothes are tried on by customers, and sports, recreation, and exercise facilities. 
     The UV-sterilization monitoring system  700  is especially useful in a hospital where hospital administrators and staff have a vested institutional interest in maintaining as clean and sterile an environment as possible. It follows that a hospital would benefit from additional ways to encourage and monitor the extent to which individual medical professionals and students observe cleanliness protocols. Accordingly, illustratively implemented, individual users may be uniquely identified to the UV-sterilization monitoring system  700  and the locker-user data file  722  may be associated in the computer memory  720  with each such user individually. Each time the locker user interacts with the UV-sterilization monitoring system  700 , he or she may actively or passively identifies himself or herself to the system  700  by, for example, use of a key-entered identification number, a scanned code such as a barcode, username and password, and/or an IP address associated with a device serving as his or her individual-user machine-to-human interfaces  750   IND . Maintained in the locker-user data file  722  associated with each locker user is information such as, for example, (i) dates and times of use, (ii) duration of use, (iii) location of garment enclosure&#39;s  100  used, (iv) types of garments  500  sterilized, and (v) elapsed time since most recent use, by way of non-limiting example. 
     By maintaining and providing access to individual-user information, an institutional user can track and analyze data files  722  for the purposes of encouraging and rewarding individual use, but can also use this data for more holistic purposes. For instance, if the institutional user such as a hospital has various garment enclosure banks  100 B situated throughout its facilities, it can—after sufficient data has been accumulated—optimize locations for the addition or subtraction of garment enclosures  100  associated with particular garment enclosure banks  100 B. Also, after initial installation and use of a certain number of garment enclosures  100  arranged in strategic locations, the institutional user could track whether there has been a corresponding reduction in infections, etc. since initial installation and/or situating of garment enclosure banks  100 B in specific locations throughout its facilities. Remote machine-to-human interfaces  750 , whether they are individual-user machine-to-human interfaces  750   IND  or institutional-user machine-to-human interfaces  750   INST , may include a computer. Additionally, individually, the various remote machine-to-human interfaces  750  may be communicatively linked to the data processing system  710  by communications network as indicated schematically in, e.g.,  FIG. 7 . As shown, hardwiring may be indicated by solid-line connections while wireless communication links are indicated by arcuate wave-front symbols. 
     The foregoing is considered to be illustrative of the principles of the invention. Furthermore, since modifications and changes to various aspects and implementations will occur to those skilled in the art without departing from the scope and spirit of the invention, it is to be understood that the foregoing does not limit the invention as expressed in the appended claims to the exact constructions, implementations and versions shown and described.
