     DETAILED DESCRIPTION 
     Reference will now be made in detail to implementations of the technology. Each example is provided by way of explanation of the technology only, not as a limitation of the technology. It will be apparent to those skilled in the art that various modifications and variations can be made in the present technology without departing from the scope or spirit of the technology. For instance, features described as part of one implementation can be used on another implementation to yield a still further implementation. Thus, it is intended that the present technology cover such modifications and variations that come within the scope of the technology. 
     Referring to the figures, a core frame comprises an upper assembly, a lower assembly, and an adjuster plate. The upper assembly includes parts that align along the user&#39;s back and rise over the user&#39;s shoulders. This is one place that attachment points can be located and the padding can be located. The upper assembly is connected to the lower assembly. The lower assembly. The overlap between the upper and lower assemblies provides a region for adjusting the core frame. The lower assembly can fit around a user&#39;s hips; it is shaped like a “C” and sculpted in vertical profile slightly inward to fit over the top of the user&#39;s hips. Strapping and padding is applied over the core frame to make it more comfortable to the user and to provide increased support and better weight distribution. When padding and strapping are in place, the technology can substantially parallel the natural curvature of a user&#39;s spine—placing the spine closer to a neutral posture position. In some embodiments, the upper assembly and the lower assembly can be made of carbon fiber. 
     The adjuster plate can be of a variety of materials such as spring steel. The adjuster plate can be substantially rectangular. As shown in the figures, each corner of the adjuster plate can have an attachment point (e.g. a hole) for connecting the adjuster plate to both the upper assembly and the lower assembly in an aligning fashion. A first of the assemblies (in the figures, the lower assembly) can have holes corresponding to those on the adjuster plate. A second of the assemblies (in the figures; the upper assembly) can have vertical slots of width substantially equal to the width of the holes in the adjuster plate and the first assembly, each slot aligned with two of the holes in the adjuster plate as shown in the figures. A fastener can be used in each of the holes to snugly adjust the overall height of the core frame, e.g., by sliding the second assembly relative to the first assembly and the adjuster plate and snugly fastening the adjuster plate fasteners, as shown in  FIG. 9A  (before adjusting) and  FIG. 9B  (after adjusting). 
     The adjuster plate can further include a series of posts (shown in the figures as a single horizontally-arranged array) that can mate with corresponding holes in a first assembly (in the figures, the lower assembly). The adjuster plate can include one or more posts in various configurations including a plurality of horizontal rows of differing numbers of posts. The first assembly is shown in the figures with a single row of holes corresponding to the posts of the adjuster plate of the figures. Posts can be canted down, can be circular, can be irregular polygons. The second assembly (the upper assembly in the figures) can include several array of holes, each array corresponding to the array of posts of the adjuster plate. In this fashion, the post can be fitted through the holes in the first assembly and adjustably fitted at various arrays in the second assembly to provide the user with a personalized vertical fit of the core frame. When the adjuster plate is made of resilient material, such as spring steel, the adjuster can be biased to have the posts engage the holes in the first and second assembly. A lip at the bottom (or top) of the adjuster plate can provide a convenient hand hold for temporarily countering the engagement bias for adjusting the core frame. 
     The adjustable support structure provided by the core frame can be used to support personal protective equipment (e.g., an armor carrier) and load carrying equipment while transferring weight to the user&#39;s hips for a wide variety of user sizes. Other mechanisms that can be used to secure the upper assembly to the lower assembly with an adjuster plate, including hook and loop, snaps, spring impelled posts, magnetically impelled posts, pneumatically impelled posts, webbing. In some embodiments, the securing mechanism can be integrated into the upper and lower assemblies and the adjuster plate can be dispensed with. 
     Attachment points on the core frame, e.g., two points at the top of the frame and two points at the bottom of the core frame, can be used to attach the various personal protective equipment and load carrying equipment to the core frame. 
     The lower assembly includes a hip belt portion that can wrap around a user&#39;s waist and hips. The hip belt portion of the lower assembly can be substantially rigid in the vertical direction and radially resilient. A flexible securable belt can be attached to the lower assembly (e.g., permanently or releasably), in a position to allow a user to secure the overall system substantially atop the user&#39;s hips. The belt can include attachment points (e.g., MOLLE) for the equipment of the type described above. A hip pad can be soft sewn and can slide over each of the ends of the hip belt (or in some embodiments, the belt regions of the lower assembly). The soft sewn portions of the hip belt can comprise as sandwich fold secured by hook and loop for various purposes such as to accommodate a ballistic panel, to be used as storage for excess webbing. 
     Removable lumbar padding assembly can be included in the technology. The lumbar padding assembly can be removably attached to the lumbar portion of the core frame. The attachment points can be the same corner fasteners used to secure the lower assembly to the adjuster plate. The lumbar padding assembly can accept various thicknesses and shapes of padding materials to conform the padding to the back of various users. 
     The upper yoke portion of the core frame upper assembly can be cut low at the base of a user&#39;s neck so as to reduce interference with user movement, e.g., when the user tilt&#39;s his head back. In the shoulder wing region of the upper assembly (e.g., the region corresponding to the middle of a user&#39;s shoulder blades), each side (lefty, right) of the upper assembly can include a wedge elevated towards the rear external portion, e.g., to allow routing of substantially rigid stays (e.g., aluminum) so that the stays protrude just over a user&#39;s shoulder to provide spacing that substantially prevents significant loading of the user&#39;s shoulders under heavy payloads. Through the wedge and through the upper portion of the lower back are anchoring points for securing the stays to the core frame (and in some embodiments for securing the harnessing). 
     Near the end of each shoulder wing, the upper assembly holes for further attachment points can be included for anchoring points for an adjustable shoulder strap that can run from the attachment point to the belt region of the lower assembly (e.g., attaching to that region of the lower assembly or to a covering or attachment point thereof). The shoulder strap can be straight from shoulder to hip or curved (e.g., in a radius about the shoulder and then to the hip). The strap can be padded. The strap can include a lateral stiffener, and can have webbing as a primary load bearing element. The webbing can be laterally contoured to the strap, e.g., by applying a plurality of substantially high tension thread lines on the inside radius of each curve. The entire webbing can be sewn flush to the strap. The strap can be secured to the core frame by various methods, e.g., a grommet through webbing at the top of the shoulder strap and using a rivet to attach. 
     A harness assembly can be included using a variety of materials to allow a user to hand carry the technology, or for others to extract, drag, or carry a user who is wearing the technology. The harness assembly can comprise a handle that would extend above the nape of the neck of a user, e.g., allowing a person to grab and drag a user wearing the technology. The harness can attach to the upper yoke at the same location as the stays, including extending from each upper yoke attachment point diagonally across the upper assembly in the direction of the lower assembly, e.g., both sides together forming an “X” across the back of the upper assembly, then the harness can be routed through the user&#39;s legs and be attached to the front hip portion of the technology. The attachment points at the hip can correspond to the hip attachment points of the shoulder straps, thus creating a body harness. A base of Kevlar coated with nomex having an outer coating to protect it from externals. Materials such as this provide a harness that is resistant to various environmental extremes, e.g., extreme heat from a fire. 
     The technology can include a variety of carriers, e.g., military ballistic carriers, aprons, protective apparel or equipment, occupational equipment, various tactical, medical equipment, including a military tactical carrier for carrying body armor. 
     When a cummerbund is used is can snug the user&#39;s body to the frame snugly. This encourages back posturing and position to go to neutral position. This can lessen loading on the spine. 
     Because the core frame provides support, some portions of conventional armor carriers can be omitted, e.g., stiffeners, padding, etc. The technology can provide an interface to existing armor carrier pieces, e.g., through the use of adapters. 
     Webbing on carriers of the technology provide attachment points for items such as collars, deltoid protection, lower back armor, and groin protection. The carriers are adapted for routing wiring for electronics such as a radio antenna. Such adaptations include ports in the fabric for routing wiring in a fashion protected from the elements. The carrier provides attachment points for quick-release mechanism. 
     Regarding stays, e.g., aluminum stays, attachment can be through adhesives, through molding the stays into elements of the core frame, through sets nuts, rivet screws. The stays can share a common lower attachment point, e.g., a depicted in the mid-back in the figures. Each stay then has an attachment point on the wedge in each upper assembly shoulder wing. This can provide separation, e.g., 1″, from both the top of the wearer&#39;s shoulder and the front of the wearer&#39;s shoulder, thus allowing shoulder movement without substantial should restriction. The technology can include a pack system releaseably attachable to the core frame, with or without the armor carrier underneath. The pack can be truncated pear shaped to provide a truncated pear shape. The pack can be 10″ across at the top, 14″ across near the bottom and 12″ at the bottom. The pack can be 6″ deep at the top, 8″ deep at the bottom, about 2000 cubic inches. The pack can be about 22″ tall not counting addition 5″ of collapsible collar that can be cinched tight to close the top of the bag. There can be three (3) points of access, top, and each of left and right side (using a zipper panel). The body can be of two-ply fabric or multiple fabrics (e.g., mil spec cloth on the outside and pack cloth on the inside with slick side facing inside—allowing routing of cables and other items between the layers using ports in the layers. The pack can be attached to the frame via a quick release system or other known attachment mechanisms, including permanent mounting. The pack can have one large inner chamber. 
     Referring to  FIG. 1 , a front view of a core frame  100  of the present technology is illustrated—while in  FIG. 2 , a rear view of the core frame  100  is illustrated. The core frame  100  can include an upper assembly  110  releasably attachable to a lower assembly  120  using an adjuster plate  130  (not shown in  FIG. 1 ). 
     As shown in  FIG. 6  (left side perspective view), the upper assembly  110  formed substantially in the shape of a “Y,” can be shaped to substantially mirror the natural thoracic curve of a user&#39;s spine. As illustrated in  FIG. 4 , a rear view of an upper assembly  110  is illustrated showing fastener slots  114  and a set  116  of rows  117  of anchor point mating holes  118 . As illustrated in  FIG. 2 ,  FIG. 4 , and  FIG. 6 , the upper assembly  110  includes two (2) wedges  112  for anchoring straps and/or stays. 
     As shown in  FIG. 1  (front view),  FIG. 2  (rear view),  FIG. 6  (left side perspective view), lower assembly  120  can be shaped to substantially mirror the shape of a user&#39;s hips, with a mating section  122  for mating with the upper assembly  110  and the adjuster plate  130 . Mating section  122  includes fastener holes  124  positioned to align with upper section fastener slots  114  and a row of lower assembly anchor point mating holes  127  positioned to align with a selectable one of the rows of upper assembly anchor point mating holes  117  in the assembled core frame  110 . 
     Adjuster plate  130 , as illustrated in  FIG. 2  and  FIG. 7  can include a plurality of holes  132  for accepting releasable fasteners and at least one row  134  of anchoring points  135 . Adjuster plate  130  can be attached to upper assembly  110  and lower assembly using releasable fasteners through fastener holes  132  in the adjuster plate  130 , and through fastener slots  114  in the upper assembly  110 , and through fastener holes  124  in the lower assembly. Each of the anchoring points  135  in the row  134  of anchoring points can be inserted through corresponding the holes of a row  117  of mating holes in the upper assembly  110 . The particular row chosen will determine the height of the overall core frame. The adjuster plate anchoring points  135  can also penetrate the lower assembly mating holes  127 . The entire assembly can be secured by securing fasteners through the fastener holes  124  and  132  and the fastener slots  114 . Adjuster plate  130  can be fabricated from a biasable material, such as spring steel so that adjuster plate central portion  138  biases anchoring points  135  through the corresponding anchoring holes in upper portion  110  and lower portion  120 . As shown in  FIG. 8 , adjuster plate central portion  138  is flanked by two wing portions,  710   a  and  710   b , separated from adjuster plate central portion  138  by gap  720   a  and  720   b  respectively. Adjuster plate  130  can include a tail portion  136  to facilitate gripping of the adjuster plate to release the anchoring points  135  from holes  124  and  132  to adjust the overall height of the core frame  100 .
