Title: Encryption unit quick insert/ quick removal housing

Description:
BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      This invention relates generally to computer and communication networks, and more specifically, to a mounting method and bracket for the encryption unit portion of a deployable secure communication system used to provide secure voice, video and data services to multiple remote users.  
      2. Background of Related Art  
      Conventional deployable communication systems exist. For instance,  FIG. 6  is a depiction of a particular conventional deployable secure communication system.  
      In particular, as shown in  FIG. 6 , a secure encryption module such as defined by KIV-7 standards  912  with suitable interface hardware is utilized in a direct connection path between a remote user  910  and a wireless connection to a similarly secure receiver via a satellite antenna  914 . In the conventional system of  FIG. 6 , an ISDN link is utilized between the module  912  including a KIV-7 encryption module, and a suitable satellite two-way communication transceiver and antenna  914 .  
      However, such conventional systems are typically physically large. Typical secure, deployable communications systems fill a van or small vehicle. Part of the reason for the significant size of such systems is the need to accommodate racks of communications equipment, including a rack-mounted, standardized encryption unit, e.g., a Type 1 KIV-type encryption device such as a KIV-7, pictured in  FIG. 7 .  
      In particular,  FIG. 7  depicts the conventional casing and required connections to a KIV-7 unit.  
      As shown in  FIG. 7 , a KIV-7 unit  700  includes four separate connector sockets  710 - 716 . Two of the connectors are 9-pin connectors, the other two are 37-pin connectors. One of the 9-pin sockets  710 ,  716  is a male-type connector, and the other  710 ,  716  is a female-type connector. Similarly, one of the 37-pin connectors  712 ,  714  is a male-type, while the other  712 ,  714  is a female-type. The use of male and female-type connectors prevents improper installation cabling to the KIV-7  700 .  
      It should be noted that a KIV-7 has no handles, and is typically rack-mounted into a rack of equipment.  
      As can be appreciated from the KIV-7 encryption unit depicted in  FIG. 7 , a significant amount of access must be provided to the rear of the KIV-7 so that the KIV-7 may be replaced if maintenance is required. Such access is typical in most rack-mounted equipment enclosures.  
      Some conventional deployable secure communications terminals fill a van with equipment. As can be appreciated, in a military environment size is to be minimized so as to expand military options of deployment.  
      There is a need to reduce the size of a deployable secure communications system.

     SUMMARY OF THE INVENTION  
      In accordance with the principles of the present invention, a quick insert/quick release mounting bracket for an encryption unit comprises a top surface. A right surface is secured to the top surface. A bottom surface is secured to the right surface. A left surface is secured to the top surface. A rear surface having at least four connectors is mounted thereon. The connectors are normally associated with individually secured cables. The rear surface is movably secured in a rear of the mounting bracket so as to allow for a given amount of left/right and up/down tolerance in alignment between the at least four mounted connectors mounted on the rear surface and a matching at least four connectors on a rear of an encryption unit to be slid over the top surface, the bottom surface, the left surface, and the right surface, and into connection with the at least four mounted connectors.  
     DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS  
      In a commercial environment where competitors offer portable, secure communication terminals that fill a van or small vehicle, one vendor, TeleCommunication Systems, Inc. (TCS) of Annapolis, Md., provides a portable secure communication terminal, and even a deployable secure communications terminal that is uniquely packaged to be small enough to be carried in a suitcase-sized enclosure. Current products from TCS are suitably small enough to be carried by a paratrooper, e.g., into hostile territory. This is significant as prior systems could not be deployed until an aircraft or other transport system carried them directly to the relevant location.  
      The reduction in size and weight requirements of a deployable, secure communications terminal are due in no small part to the development of a highly compact mounting bracket  100  for the heart of the secure system—the Type 1 KIV-type encryption unit, shown in  FIG. 1 .  
      A quick insert/quick release encryption unit mounting bracket  100  in accordance with the principles of the present invention is disclosed for an embodiment based on the KIV-7  700  (manufactured by Mykotronx) Type 1 encryption device. The disclosed quick insert/quick release mounting bracket  100  allows a Type 1 encryption device such as the KIV-7  700  to be quickly inserted and perhaps more importantly, quickly removed (e.g., in the event of the need for an extremely quick evacuation of a military site). Importantly, the disclosed quick insert/quick release mounting bracket  100  allows for removal of a Type 1 encryption device  700  such as a KIV-7 without the need to physically unscrew or otherwise disconnect individual cable assemblies.  
      In accordance with the principles of the present invention, the disclosed quick insert/quick release encryption unit mounting bracket  100  allows a Type 1 encryption device  700  such as a KIV-7 to be inserted by simply sliding the KIV-7  700  into place, or to be removed by simply pulling the KIV-7  700  straight out in the direction of the front of the unit. This facilitates a quick swap out of the KIV-7  700  in the event of failure, or in the event that the sensitive nature of the encryption unit  700  needs to be quickly removed to protect the encryption unit  700  from falling into enemy hands.  
      The KIV-7  700  is typically installed into a multi-bay rack mount shelf assembly that contains a power supply, or in some cases simply placed on a shelf. The design of the KIV-7  700  requires the physical connection of a minimum of three cable assemblies; power input, data input, and data output. The process of inserting the KIV-7  700  into the shelf assembly and connecting the three cable assemblies typically requires several minutes of an individuals time and open access to the rear of shelf for connection and securing of the cable assemblies. Removal of the KIV-7  700  also requires several minutes of time and open access to its rear, typically provided by a rack mount enclosure. Typical rack mount enclosures are 6 feet tall, 2 feet wide, by 3 feet deep.  
      Through the implementation of the disclosed encryption unit mounting bracket  100 , an encryption unit  700  such as a KIV-7 can now be inserted and ready for operation in a matter of just a few seconds. Importantly, the mounting bracket  100  need not provide a routine operator with access to the rear of the encryption unit  700 , further facilitating a quick release of the encryption unit  700 .  
      If removal of the bracketed encryption unit  700  becomes required, the encryption unit  700  may be gripped (e.g., by use of the key) and pulled out in just a few seconds without the need for direct access to the rear of the unit.  
      Conventional installations of a Type 1 encryption unit  700  such as the KIV-7HS or other KIV-type devices (e.g., a KIV-21) required cabling to the rear of the unit  700 . The present invention enables the installation and removal of a Type 1 encryption unit  700  without the need to secure or remove numerous cables connected to the rear of the encryption unit  700 .  
       FIG. 1  shows an exemplary quick insert/quick release encryption unit mounting bracket within a deployable secure communications system, in accordance with the principles of the present invention.  
      In particular,  FIG. 1  shows an exemplary quick insert/quick release encryption unit housing and mounting bracket  100  placed within a casing  120  intended to contain a deployable, secure communications terminal.  
       FIG. 2  shows an outside, rear view of the exemplary embodiment of the quick insert/quick release encryption unit mounting bracket shown in  FIG. 1 .  
      In particular,  FIG. 2  shows a rear plate  202  for fixedly mounting connectors to mate with appropriate connectors on the rear of a Type 1 encryption unit such as the KIV-7. The quick insert/quick release mounting bracket  100  further includes a top  206  (and matching bottom not shown), a left side  204  and a matching right side (not shown).  
      The top  206 , bottom, left side  204  and right side of the quick insert/quick release mounting bracket  100  preferably include holes or other shaped cut-out areas  210 . The cut-out areas  210  provide a reduction in the weight of the overall secure, deployable communications terminal. Moreover, the cut-out areas  210  also provide for cooling of the KIV-7, which fits snugly inside the quick insert/quick release mounting bracket  100 , with sufficient tolerances to allow easy sliding of the KIV-7 into the quick insert/quick release mounting bracket  100  from its front end  250 .  
      The bracket may be made of any suitable metal, e.g., aluminum. In such case, individual sides, top and bottom may be made separately from flat stock, and screwed together with appropriate screws  260 . The bracket may also be manufactured from a plastic material, e.g., Delron™. Because plastics tend to insulate thermally more than do metals, the use of cut-out areas  210  are more important from a ventilation point of view. The quick insert/quick release mounting bracket  100  may also be formed in a singular piece of metal or plastic. A combination of plastic and metal portions is also possible.  
      Importantly, the rear plate  202  of the quick insert/quick release mounting bracket  100  is not fixedly mounted to the sides, top or bottom of the quick insert/quick release mounting bracket  100 . Rather, it is captured in appropriate slots in the top, bottom and sides and left floating with some amount of tolerance (e.g., ⅛″ in left/right and up/down directions). This ‘floatation’ allows movement of the connectors mounted to the rear plate  202  with respect to the matching connectors on the rear of the KIV-7 upon insertion of the KIV-7 into the mounting bracket  200 . This ‘floatation is important because of variances in the exact placement of the connectors with respect to the rear of the KIV-7 unit  700 .  
       FIG. 3  shows the rear, floating connector plate  202  of the quick insert/quick release encryption unit mounting bracket having 4 connectors mounted thereon to mate with complementary connectors mounted on the rear of the encryption unit, in accordance with the principles of the present invention.  
      In particular,  FIG. 3  shows particularly measured placements of the connectors on the rear plate  202 . Of course, these measured placements relate to the exemplary KIV-7 in particular used in the disclosed embodiments. However, the invention is to be understood as relating to KIV-type encryption units in general.  
       FIGS. 4A  to  4 E show exemplary side, top and bottom components of a first embodiment of a quick insert/quick release encryption unit mounting bracket shown in  FIG. 1 .  
      In particular,  FIGS. 4A  to  4 C show views of the right side  203  of the quick insert/quick release encryption unit mounting bracket  100 , including the exemplary cut-out areas  210 .  FIGS. 4D and 4E  show views of the top  206 . The bottom in a first embodiment is the same as the top  206 . However, the bottom (or top  206 ) surface may be utilized to provide a pull-tab against a KIV-7 unit  700  once inserted into the quick insert/quick release mounting bracket  100 .  
      For instance,  FIGS. 5A and 5B  show an exemplary separable T-shaped pull  516  to allow quick separation of an installed KIV-7 unit  700  from a quick insert/quick release encryption unit mounting bracket  100   b , in accordance with another aspect of the present invention.  
      In particular,  FIG. 5A  shows a T-shaped pull  516  formed from a portion of the bottom plate  508  of the mounting bracket  100   b.  The T-bracket  516  may be formed merely by cutting a bottom plate  506  along cut lines  521 - 524  to separate the T-shaped pull  516  from the remaining portions  512 ,  514  of the bottom plate.  
      Importantly, the T-shaped pull  516  includes a lip  532  that extends upwards behind the KIV-7. The rear plate  202  preferably includes a matching cut-out area to accommodate the gripping lip  532 .  
      The T-shaped pull  516  includes finger holes  520  allowing a user to grab hold of the T-shaped pull  516  and pulling it in the ‘REMOVE’ direction of the arrow shown in  FIG. 5A  to remove both the T-shaped pull  516  together with the KIV-7 previously inserted into the mounting bracket  100 .  
      The T-shaped pull  516  may be secured when inserted into the mounting bracket  100  merely within the tolerances created between a surface upon which the bottom of the mounting bracket  100  is resting on, and the bottom of the KIV-7  700 . If desired, the T-shaped pull  516  may include tongue and groove (or other shape) type mating along edges  521 ,  522  with the remaining surfaces  512 ,  514  of the bottom plate  508 .  
      The disclosed encryption unit mounting bracket  100  allows for use of an encryption unit  700  such as the KIV-7 in areas where space is extremely limited, such as in a deployable secure communication system.  
      The disclosed encryption unit mounting bracket  100  does not require securing of any physical connection of any cable assemblies, and thus, requires no hand tools. An individual may insert and remove an encryption unit  700  such as a KIV-7 in just a few seconds, not minutes as in conventional devices utilizing the KIV-7 encryption unit  700 .  
      Moreover, the sizing of the encryption unit mounting bracket  100 , and the need for operator access only to the front of the encryption unit  700 , the overall size of a product such as a deployable secure communication system can be reduced.  
      The disclosed quick insert/quick release encryption unit mounting bracket  100  is constructed of any suitable sturdy material, e.g., aluminum or steel, or even a high quality plastic material. The encryption unit mounting bracket  100  comprises five individually manufactured sections (top, bottom, sides and rear), though one or all four of the top, bottom and sides of the mounting bracket  100  may be formed or otherwise manufactured as a single piece. The rear plate is importantly not formed with the top, bottom and sides, to allow adjustment to a wide range in tolerance experienced in mounting of rear connectors on typical KIV-7 units  700 .  
      Individual side and top sections are assembled with high quality screws and the rear plate  202  is designed to float so as to allow for minor alignment differences in the rear panel connectors of the KIV-7  700 .  
      The cable assemblies/connectors are fixed to the rear panel  202  with screws, but importantly the back panel  202  is allowed to freely float in the back end of the mounting bracket  100  to allow for a significantly large variation in physical tolerances in the placement of connectors on the back of the encryption unit  700 .  
      While the invention has been described with reference to the exemplary embodiments thereof, those skilled in the art will be able to make various modifications to the described embodiments of the invention without departing from the true spirit and scope of the invention.
