PRIORITY INFORMATION 
       [0001]    The present application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Patent Application Ser. No. 61/924,350 entitled “Cable Management System,” filed Jan. 7, 2014, the entire contents of which are expressly incorporated herein by reference. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    1. Technical Field 
         [0003]    The embodiments described herein generally relate to cable management systems. More particularly, the embodiments relate to a cable management and active-user notification system for use in a conference room environment. 
         [0004]    2. Background 
         [0005]    Currently available conference room audio/video (AN) systems typically do not provide a simple solution for the interface or switching of portable electronics sources to a primary display and audio system. Conventional systems generally have one or more complex, remotely located integrated control panels/interfaces to allow switching between devices (e.g. computers, video players, audio/voice amplifiers, internet access, among others), other room controls (lighting, drapery and shade systems, air-conditioning, heating, and ventilation), and A/V controls, making it confusing to just switch control of the one or more plurality of devices/systems within the room from one device to another. 
         [0006]    Moreover, it is not always apparent (to the other occupants) whose device is controlling the one or more A/V devices because normally, the light emitting diodes (LEDs), or other visible notification means, which are illuminating the control panel, usually face one direction (generally towards the primary user, but not always), making it even more difficult for the primary user to control the one or more systems. Additionally, installation of conference room A/V systems is fairly time consuming and expensive. 
         [0007]    Furthermore, integrating pass-through power access to portable devices is also cumbersome, as power outlets are typically well below the surface of the table, and also can be located in obscure, difficult to access (to meet Underwriter Laboratories® (UL) requirements), water-resistant locations. 
         [0008]      FIGS. 1 and 2  illustrate views of a conventional conference room  100  with A/V devices that can generally be found in a large amount of conference rooms in corporations in the U.S., among other places. As those of skill in the art can appreciate, use of “conference rooms” and A/V control systems is not limited to corporations, but can further includes similar environments, such as classrooms (high schools, and colleges), government entities (such as different agencies, and the military), and just about any such group/entity that has a need to regularly meet and hold conferences to convey information to a plurality of people. 
         [0009]    Conference room  100  includes display screen  112 , table  118 , speaker phone  114 , laptop-control panel interface (CP interface) box  120 , and A/V panel  102 . A/V panel  102  includes Blu-Ray video disk player  104 , amplifier  106 , video cassette recorder and digital video disk (VCR/DVD) player  108 , and lighting control  110 . Located near, or part of control panel  102 , is wireless gateway  122 , which can receive wireless signals according to the one or more wireless protocol(s) in use (Wi-Fi, Bluetooth, among others), and control one or more of the devices within control panel  102 . Connecting control panel (CP)  102  to laptop-control panel interface box (CP interface)  120  is CP interface-CP cable (CP cable)  128 , and laptop  116  is connected to CP interface  120  via laptop—CP interface cable (CP interface cable)  130 . It can be appreciated by those of skill in the art that although this background section, as well as the detailed description of the embodiments below, reference is made solely to laptop  116  as the device that interfaces to CP  102 , other types of both portable and non-portable electronic processing devices can be used within any of the systems described herein; however, in fulfillment of the dual purposes of clarity and brevity, reference shall only be made to “laptops  116 ” (which are fairly ubiquitously used in conference rooms to provide presentations), but other types of devices can also be used, such as a personal computers, so-called smart phones (3G/4G-LTE), tablets, among other computer/processing devices. 
         [0010]    CP  102 , and one or more of the devices contained therein, are connected to ceiling mounted projector  124  that can display video, photos, or computer-generated images. CP  102 , and one or more of the devices connected therein, are also connected to speakers  126 , for projecting audio associated with teleconferences, videos, or computer generated videos, among other sources of audio information. 
         [0011]    Several prior art devices have attempted to solve the problems outlined above. For example, U.S. Published Patent Application No 2013/0327659 by Stathis, et al., provides a power, communications and data grommet mounted in an aperture in a work surface. The grommet includes a housing adapted to fit into the aperture, with the housing comprising a cap removably connected to a liner. The liner includes an upper liner and a lower liner, with the upper liner flaring outwardly to prevent the grommet from falling through the aperture, and a substantially cylindrical lower liner having a threaded outer surface, and a lock ring having inner threads to be threadably attached to the lower liner. 
         [0012]    PCT Published Patent Application No. WO 2013 111125 A2, by J. Kramer, describes a pop-up enclosure system for electronic equipment that includes a receptacle adapted for mounting in a work-surface and which contains one or more electrical outlets for connection of equipment thereto. The pop-up enclosure system by Kramer further includes a bezel supported by the receptacle and which is adapted for countersinking in said work-surface. A top plate is dimensioned for closing an opening defined by the bezel, and a hinge is mounted at an edge of the top plate and the bezel for hingedly attaching the top plate to the bezel so as to allow rotation of the top plate from a closed position to a fully open position wherein the edge of the top plate abuts an upper surface of the bezel. A releasable resilient opening force is the receptacle and articulated to the top plate for opening the top plate. 
         [0013]    Another prior art grommet is described in U.S. Published Patent Application No. 2012/0305868, by Callahan et al., which provides a wall grommet that can be installed through the surfaces of walls to route wiring into the walls&#39; interior spaces. The wall grommet is allegedly configured for running power cords inside walls and presenting the electrical connectors of a power cord in a manner such that power cords are hidden from view. The grommet can include a power module and a back cover. The power module itself comprises a housing, which defines an interior space that is adapted to hold either the female connector or male connector of a power cord. The back cover can be attached to the housing to secure the electrical connector of the power cord in the housing. 
         [0014]    U.S. Pat. No. 8,007,295 to Lin discloses a reversible and concealable electrical power receptacle that includes a main body, a shaft section, an accommodating section, and an electrical outlet assembly. The electrical outlet assembly is disposed on the main body, and the accommodating section receives the main body, and the shaft section includes a first shaft member and a second shaft member. The second shaft member is coupled to the main body and perpendicular to the first shaft member. The main body is rotatable with respect to the first and the second shaft members transversely respectively. Consequently, the main body is able to rotate transversely and perpendicularly with respect to the accommodating section in accordance with the rotational movements of the first shaft and the second shaft members, resulting in an exposed state in use or a concealed state when not in use, thereby achieving effective space utilization. 
         [0015]    A further conventional laptop cable interface device is described in a non-patent literature document that is a two-page marketing brochure, and which describes “Pixel,” which is an Office Electrics device (a UK company). The “Pixel” document describes a device that can be configured as either a power-only interface, a data-only interface, or a combined power/data interface for use on a conference table, similar to that as shown in  FIG. 1 . 
         [0016]    Thus far, the prior art&#39;s alleged solutions, describe above, provide very little in terms of integrating or providing means for accessing and manipulating conference room A/V systems by portable devices. 
         [0017]    U.S. Pat. No. 7,806,723 to Chong, et al., however, is allegedly directed to an electrical grommet device, and methods of use and manufacture thereof. Accordingly, the electrical grommet device by Chong comprises a casing that includes a grommet that includes one or more first apertures and an insertion portion, and a connection mechanism capable of being coupled to the grommet. The electrical grommet device further includes one or more electrical components located at least partially within the casing, and one or more electrical connectors located at least partially within the casing and coupled to the one or more electrical components. The insertion portion of the electrical grommet device can allegedly be removably placed in a grommet hole from a first side of the grommet hole, and the electrical grommet device can further allegedly be removably coupled to the connection mechanism at a second side of the grommet hole opposite the first side. 
         [0018]    U.S. Pat. No. 7,163,409 to Chen, et al, describes a modular integrated socket apparatus that includes a shell, a pop-up structure, an adapter module, a connector base, and a coupling device. The pop-up structure contains one or more electrical connectors, including power and signal connections. The pop-up structure, the adapter module, the connector base, and the coupling device are mounted in the shell. The adapter module is electrically connected to the connector base. When in use, the shell and the adapter module can be lifted and located higher than the table by use of the pop-up structure and the coupling device. As a result, access can therefore be made of the power and signal connectors on the pop up structure. 
         [0019]    The table top connection box shown in U.S. Design patent No. D553,306, which apparently combines one or more electrical power and signal connectors in a single connection box that can be mounted on a table top. 
         [0020]    U.S. Pat. No. 3,646,244 to Cole describes an adjustable floor receptacle mount that includes a housing movable within a stationary casing fitted into a circular opening in a concrete floor. The housing and the casing are each formed of a pair of interlocking extruded channel structures whose walls are shaped to facilitate the installation and operation of the floor receptacle mount. In order to simplify the withdrawing of the housing from a recessed position within the casing, a cap provided on a cover plate for the housing and operating in conjunction with a latching mechanism pops up when the housing is unlatched. The cap thus provides a convenient handle by which the housing can be quickly pulled out of the casing in the floor when it is desired to use the electrical service provided by the receptacles on the sides of the housing. 
         [0021]    Thus, while the prior art described generally devices that provide table and floor recessed devices that provide for interconnection to one or more of power and signal connections, there is a need for an improved means for accessing and manipulating conference room A/V systems by portable devices. 
       SUMMARY OF THE INVENTION

       DETAILED DESCRIPTION OF THE INVENTION 
       [0084]    Unless the context clearly requires otherwise, throughout the description and the claims, the words ‘comprise’, ‘comprising’, and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to.” The embodiments are described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the inventive concept are shown. In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity. Like numbers refer to like elements throughout. The embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the inventive concept to those skilled in the art. The scope of the embodiments is therefore defined by the appended claims. The detailed description that follows is written from the point of view of a control systems company, so it is to be understood that generally the concepts discussed herein are applicable to various subsystems and not limited to only a particular controlled device or class of devices, such as cable management systems for use with A/V equipment in conference or meeting rooms. 
         [0085]    Reference throughout the specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with an embodiment is included in at least one embodiment of the embodiments. Thus, the appearance of the phrases “in one embodiment” on “in an embodiment” in various places throughout the specification is not necessarily referring to the same embodiment. Further, the particular feature, structures, or characteristics may be combined in any suitable manner in one or more embodiments. 
       MODE(S) FOR CARRYING OUT THE INVENTION 
       [0086]    The different aspects of the embodiments described herein pertain to the context of cable management and interactive control electronics to facilitate interconnection of portable electronic devices to an A/V control system in a conference room, but is not limited thereto, except as may be set forth expressly in the appended claims. According to different aspects of the embodiments, described in greater detail below, a cable management hub is provided that includes one or more buttons, indicators, and cables. The cable management hub provides an interface between a user&#39;s electronic processing device through the cables of the cable management hub. The electronic processing device is generally a laptop, but not necessarily limited thereto, that can use software applications stored thereupon to generate audio-visual signals that can be used by the audio-visual presentation equipment present in, for example, a conference room, to be displayed or presented. Since there can be multiple users of the audio-visual equipment in the conference room, it is not always clear who is generating the audio-visual data that is being presented and displayed on, for example, a large LED panel. Pressing one of the buttons on the cable management hub allows a user to assert control over the audio-visual equipment, so that user&#39;s signals can be displayed on the panel (or other signals presented, dependent on the type of signal); the indicators can show (by illuminating) which user is in control to all of the other users, or occupants in the room, and also can indicate other status conditions. 
         [0087]      FIG. 3  illustrates a perspective view of cable management hub (CMH)  300  on a section of conference table  118  according to an embodiment. Shown in  FIG. 3  is CMH  300  that includes first and second capacitive buttons  308 ,  314 . As those of skill in the art can appreciate, capacitive sensing is a technology based on capacitive coupling, which takes human body capacitance as input. Capacitive sensors detect anything that is conductive or has a dielectric different from that of air. As further can be appreciated by those of skill in the art, first and second buttons  308 ,  314 , do not necessarily need to be capacitive buttons; other technologies for buttons work equally as well. But, in fulfillment of the dual purposes of clarity and brevity, buttons  308 ,  314  will be from heron in referred to only as capacitive buttons. 
         [0088]    CMH  300  further includes indicators  306 ,  312 , one each for buttons  308 ,  314 , respectively. According to further aspects of the embodiments, indicators  306 ,  312  are LEDs, and can be illuminated in different colors, and different lighting patterns to indicate different actions, which can be seen by other users or occupants to note certain status conditions, or who is controlling the audio-visual presentation equipment. These actions will be discussed in greater detail below. As those of skill in the art can appreciate, the indicators are not limited to LED based technologies, as other types of indicators can also be used herein. Further shown in  FIG. 3  are laptop  116  cable connectors  316   a - c . As those of skill in the art can appreciate, there need not be three connectors in CMH  300 , as there can be none, one, or any number that can be engineered into the footprint of CMH  300  according to an embodiment. However, as those of skill in the art can appreciate, certain connector types of fairly ubiquitously used in the laptop industry: these would include universal serial bus (USB) cable connectors, Ethernet cable connectors, and high definition multimedia interface (HDMI) cable connectors, “regular” video 9 pin cable connectors, among others, collectively shown as  316   a - c . Also part of CMH  300  is 120 VAC power connector  310 . 
         [0089]    CMH  300 , as shown in  FIG. 3  (and others) is generally circular in shape, which makes installation relatively easy into conference table  118 . That is, a hole-saw of the appropriate diameter can be used to drill a hole through the top of table  118 , and CMH main assembly  302  can be placed therein, with mounting collar  304  resting on an upper surface of table  118 . Then, tightening collar  318  can be screwed onto CMH main assembly  302  on the threads as shown, from below the upper surface of table  118 , to securely fit CMH main assembly  302  to table  118 . The cables (some of which have already been described, and some of which are described in greater detail below), can then be inserted into CMH main assembly  302  (through a grommet, cable clamps, or other similar means), and then connected to first and second buttons  308 ,  312 , first and second indicators  306 ,  310 , and 120 VAC power connector  310 . 
         [0090]      FIG. 4  illustrates use of cable management hub  300  in a perspective view of conference room  400  with an A/V system according to an embodiment. Similarly to the environment of  FIGS. 1 and 2 , conference room  400  includes many of the same devices, including display screen  112 , table  118 , speaker phone  114 , laptop-control panel interface box  120 , and A/V panel  102 . A/V panel  102  includes Blu-Ray video disk player  104 , amplifier  106 , video cassette recorder and digital video disk (VCR/DVD) player  108 , and lighting control  110 . Located near, or part of CP  102 , is wireless gateway  122 , which can receive wireless signals according to the one or more wireless protocol(s) in use, and control one or more of the devices within CP  102 . Connecting CP  102  to CMH  300  is CP cable  128 , and laptop  116  is connected to CMH  300  CP interface cable  130 . However, as further shown in  FIG. 5 , CP interface cable  130  connects to other circuitry before the signals carried therein are carried to CP  102 . 
         [0091]    CP  102 , and one or more of the devices contained therein, are connected to ceiling mounted projector  124  that can display video, photos, or computer-generated images. CP  102 , and one or more of the devices connected therein, are also connected to speakers  126 , for projecting audio associated with teleconferences, videos, or computer generated videos, among other sources of audio information. 
         [0092]      FIG. 5  illustrates cable management system (CMS)  500  using CMH  300  for accessing and manipulating A/V systems within conference room  400  by laptops  116  (among other processing electronic devices), and for indicating which laptop  116  has control of CP  102  according to an embodiment, and  FIG. 6  illustrates a flowchart of method  600  for operating CMS  500  of  FIG. 5  according to an embodiment. Operation of CMS  500  will be discussed in the context of method  600  shown in  FIG. 6 , though those of skill in the art can appreciate that use and operation of CMS  500  is not limited to any particular order of steps of method  600 , nor is use of CMS  500  limited to method  600  in any form. 
         [0093]    CMS  500  includes CMH  300 , which is shown to include hub circuitry  510 , and lines  502 ,  504 ,  506 , and  508 , which connect first button  308 , first indicator  310 , second indicator  312 , second button  314  to hub circuitry  510 , respectively. Hub circuitry  510  is connected to digital media transmitter (DMT)  514 , but as those of skill in the art can appreciate, hub circuitry  510  can itself be part of DMT  514 , and the respective lines  502 ,  504 ,  506  and  508  can be connected to DMT  514 , without any loss of functionality of either device. Furthermore, DMT  514  and digital media switch  518  (discussed in greater detail below), whether taken alone or in combination, encompass additional functions than what is described in conjunction with CMH  300  according to further embodiments. 
         [0094]    According to an embodiment, hub circuitry  510  contains circuitry that receives signals from first and second buttons  308 ,  312 , processes them (i.e., performs a de-bounce process, and/or translates them to a different signal level, and/or makes them differential, among other processing techniques, all of which can be considered to be incorporated into the different aspects of the embodiments), and transmits them to DMT  514   a , which then integrates them (and other signals, such as the video signals output from laptops  116 ) onto cable  516   a  to be transmitted to DMS  518 . The process of receiving the signals from hub circuitry  510 , processing them (as described above), and then transmitting them to DMS  518  by DMT  514   a  is known to those of skill in the art, and therefore since the aspects of the embodiments can be understood without a detailed discussion thereof, it will be omitted in fulfillment of the dual purposes of clarity and brevity. It can be appreciated by those of skill in the art that there can be multiple CMHs  300  within a typical conference room environment, each with a respective DMT  514 , all of which are connected to one or more DMSs  518 . While there may be a practical limit as to the number of CMHs  300 /DMTs  514  that can be connected to a single DMS  518 , according to further aspects of the embodiments, there is no fixed number, as the DMS  518  could, in theory, be made ever larger to accommodate an increasing number of CMHs  300 —DMTs  514  pairs. 
         [0095]    According to an embodiment, DMS  518  receives the signals generated by first and second buttons  308 ,  312 , and processes and acts upon them in the following manner. As described above, in a typical scenario, one or more plurality of users of CMS  500  would be using laptops  116  that contain one or more applications that can generate one or more signal types that contain the information of the one or more applications. These signals may contain data, audio, video, or any combination thereof transmitted over one or more known signal types, including but not limited to USB, HDMI, RS232 type transmissions, that can be used by one or more of the devices located within CP  102 , according to known system and methods. What is lacking in prior art systems, however, is a way of indicating who has control of CP  102 , i.e., who is generating and transmitting the data being displayed, and how is transfer of control managed in an orderly manner, and conveyed to other users/occupants of the conference room. 
         [0096]    DMS  518  monitors all of the respective signals from first and second buttons  308 ,  312 , from each of the one or more CMHs  300 . Once a user presses either of first and second buttons  308 ,  312  (the buttons are redundant; i.e., they both work substantially similarly), that user is attempting to gain control of CP  102  in order to put that user&#39;s data into the system controlled by CP  102 . DMS  518 , if already processing data from a previous user, will cause an alert condition to be displayed on first and second indicators  306 ,  314  on the particular CMH  300  of the user that pressed either of first and second buttons  308 ,  312 . The alert will let everyone in the conference room around table  118  that this user is attempting to gain control of the data throughput into CP  102 . Once DMS  518  completes processing of the existing parcel of data within its memory, it will signal all of the users of CMS  500  that control is now being diverted to the user that pressed one of first and second buttons  308 ,  312 , and the data that was being received from a respective DMT  514   a , but which was being ignored, will now start to be transmitted to CP  102  via cable  128 . The alerts can be generated by additional circuitry located within DMS  518 , and is transmitted to DMT  514   a  via cable  516   a , and then to CMH  300  and hub circuitry  510 , as described below. The description above of the operation of CMS  500  according to an embodiment was provided as a summary of the method of operation. Discussed below is method  600 , which describes in greater detail how CMS  500  operates. 
         [0097]    Method  600  begins with step  602 , wherein all of the components of CMS  500  are powered up, or have achieved power-up status. In step  604 , DMS  518  receives video signals from each DMT  514  for its respective CMH  300 , and laptop  116 . Then, in method step  606 , DMS  518  generates status signals responsive to the to be transmitted to each DMT  514  and CMH  300 , that indicates the status of laptop  116  attached to CMH  300 . At this point, it is presumed that no laptop  116  is generating video signals (according to an embodiment, “video” signals also includes accompanying audio/data signals), though that need not be the case. There are several status signals that can be determined at this point. The first is status signal (a), which represents that the no video source is connected at the particular CMH  300 . Hub circuitry  510  receives this status signal from DMS  518  and generates the appropriate drive signals to illuminate indicators  306 ,  314  as a solid blue light. As noted above, indicators  306 ,  314  are generally available to be readily visible by all the occupants of the room, or other users, so that any indication of a status is readily visible and ascertainable by others. As those of skill in the art can appreciate, hub circuitry  510  does not necessarily have to be located within CMH  300 , but that according to an embodiment, as it can be located with DMT  514 , or even as part of the circuitry that is part of DMS  518 . Nonetheless, for the purposes of making the discussion relatively easier to understand, the different aspects of the embodiments are being described as being located in different components of CMS  500 . 
         [0098]    Another status signal that can be generated at this point is status signal (b), which represents that a video source from laptop  116  is connected to its respective CMH  300 , and display device  112  is powering up. To indicate that status (b) is present, DMS  518  will generate a signal that causes indicators  306 ,  314  to be green and blinking at the appropriate CMH  300 . 
         [0099]    A third status signal that can now be generated (recalling that no laptop  116  is actually broadcasting or generating video), is status signal (c), which represents that a video source is connected at the particular CMH  300 , but not currently selected for viewing by DMS  518 . Hub circuitry  510  receives this status signal from DMS  518  and generates the appropriate drive signals to illuminate indicators  306 ,  314  as a slowly pulsing green light. Thus, according to embodiments, if there were, by way of non-limiting example, ten participants in a conference, at table  118 , and everyone had their own laptops, plugged into CMH  300 , but no one had their Microsoft PowerPoint® presentations up and running at this time, then status (c) would be present, and DMS  518  would cause all of the CMHs  300  to show slowly blinking green LED indicators  306 ,  314 . 
         [0100]    Following generation of the appropriate status indicators by DMS  518  for all the CMHs  300  that had laptops attached to them, method  600  proceeds to step  608  wherein it begins to monitor whether any of the CMHs  300  are changing their status: that is, is a video source now connected where before the source was not connected (status (b)), or conversely, has a user of a certain laptop  116  disconnected a video source that once was connected (status (a)). If no changes in any of the statuses of CMHs  300  are indicated, then method  600  continues to monitor the signals from the one or more DMTs  514  (“No” path from decision step  608 ). If, however, a change in status is indicated (“Yes” path from decision step  608 ), then method  600  proceeds to determine if the change in status is one laptop  116  asserting control over the video being displayed on panel  112 . That is, if a particular CMH  300  asserts control (“Yes” path from decision step  610 ), then one or other of first and second buttons  308 ,  312  has been pushed, and DMT  514  has transmitted that signal to DMS  514 , which recognizes it as such. In method step  612 , an appropriate status signal is generated to the appropriate CMH  300 , and status (d) is generated for that particular CMH  300 , in which both indicators  306 ,  314  are illuminated as a solid (non-blinking) green illumination. All the rest of the CMHs  300  that are part of CMS  500  with laptops  116  connected thereto will indicate status (c) in which both indicators  306 ,  314  of the other CMHs  300  are illuminated as a slowly blinking green illumination. If, however, a user presses one of the buttons  308 ,  312 , but has no video source connected to CMH  300 , then status (e) is present at that particular CMH  300 , and DMS  318  will generate signal that causes a red light to be illuminated on indicators  306 ,  314 , blinking five times slowly. 
         [0101]    According to an embodiment, in method  600 , step  614  then follows wherein video present at the CMH  300  in which one or more of first and second connect buttons  308 ,  312  was pushed is connected to and through DMS  518 , and sent to CP  102  via cable  128 . Method  600  then returns to decision step  608  to determine if there is a change in status of any of the CMHs  300 . Method  600  continually monitors outputs from all of CMHs  300  unless/until a status change is determined to have occurred (following decision step  608 , method  600  returns to steps  604 ,  606 ). As shown in  FIG. 6 , method  600  first returns to step  604 , if there is no status change, or performs steps  610 - 614  if there is a status change (with steps  612  and  614  reserved for changing control of CMS  500  according to an embodiment).
