     TECHNICAL FIELD 
     The embodiments of the present disclosure generally relate to the manufacturing and construction industries. More particularly, this disclosure relates to sealing systems for doors, such as garage doors or multi panel doors, and sealing methods which decrease air permeability and friction between doors and surfaces. 
     BACKGROUND 
     Certain structures and walls have openings which allow people, vehicles, animals, or other objects to pass through. To prevent undesirable objects from entering these openings, certain types of panels such as doors and windows are positioned within a frame constructed around the openings. An important purpose of these panels is to provide a sufficient barrier in preventing the transfer of environmental elements such as heat, noise, weather, water, and insects from one side of the panel to the other. Attempts have been made to fulfill this purpose by using various types of weather stripping between the panels and frame. For example, the weather stripping may be a strip of felt, foam, rubber, or other flexible synthetic material that provides a barrier against external weather and moisture. 
     The prior art panels may open and close by pivoting relatively to the frame, becoming a door or window. Alternatively, the panels may slide relative to the frame. An example of such a door is a car garage door which comprises several connected panels that move vertically. Sliding panels are advantageous for large openings because the door does not need a lot of space to swing inward or outward in order to open. However, an issue with such doors is that as time passes, friction develops between weather strips and door panels. Overtime, the increased friction degrades the integrity of the seal between the door and the frame causing the sealing system to be less efficient. In a swinging door, there may only be brief friction between the frame and panel in the initial opening movement or the final closing movement of the door. However, in sliding doors—like car garage doors—the panels often move upward along a vertical track before transferring to a horizontal track. To maintain a perfectly straight vertical track, the door constantly moves along the vertical track and rubs against the weather strip. Not only does this create problems for the weather strip, but it also hinders the motor or user moving the door up and down. 
     One attempt to address this issue in the prior art is a system of vertical tracks that are slightly angled away from the door opening (U.S. Pat. No. 8,684,065). In order to make the door fit snugly against the door jamb when it closes, each horizontal pair of panel hinges must be different from the hinges above and the hinges below. As the hinges connect panels that are higher in placement along the track, the wheel axle is manufactured to be further and further away from the hinge point. The disadvantage is that the upward friction is only slightly decreased and there is the need for many sizes of hinges to be created for just one door. 
     Another attempt to address this issue in the prior art is a system using a clamshell module that allows doors to be kept away from the seal of the door jamb as they move up and down along the vertical track (PCT/CA2007/000024). While this system is an improvement on prior art, one major disadvantage is the need to use custom made hinges that are not readily available in the market, further increasing the cost to install this system. 
     SUMMARY 
     Provided herein is a system that addresses deficiencies of the art with respect to effectively creating a seal between a panel and a frame and is an improved method of allowing a door to move freely up or down along a track and also to press securely against the door jamb when the door is closed. A sealing assembly may be coupled to a garage door system, such as the garage door systems that are known in the art. The combination of the sealing assembly and the garage door system is referred to herein as the sealing system. 
     In certain embodiments of the present invention, a sealing system for connecting a panel to a frame comprises: a cam-stop assembly, at least one cam assembly, a stop brace, and at least one linkage connector connecting at least one cam assembly to a cam-stop assembly. In some embodiments, a sealing assembly comprises a plurality of cam stop assemblies and a plurality of stop braces. The cam stop assembly allows vertical movement to be converted to rotational movement forward as it engages a stop brace. This forward movement causes the door to press firmly against the door jamb. The system may also, in some embodiments, include a counter-tension system which allows the door to retract into a neutral position away from the door jamb when the cam stop assembly is not engaging the stop brace.

In the preferred embodiments upper linking bracket  610   a  of a first linking assembly (or of any linking assembly) is not directly coupled to a panel pivot axel  117 . 
     Combination of Cam-Stop Assemblies 
     First cam-stop assembly  120  may be a cam assembly coupled to an elongated stop, which may be substantially parallel with the horizontal length of a door panel. A second cam assembly may be similar or equivalent to the first cam assembly provided that the second cam assembly may be coupled to a caster wheel  210  that may be rotationally and operably coupled to the second guide rail. Standard garage doors, as viewed from someone standing at the main entrance into the garage and facing the garage door, generally have a left side and a right side. The first cam-stop assembly  120  may be disposed along the wall that is to the right of the garage door; the second cam-stop assembly  120  may be disposed along the wall that is to the left of the garage door. 
     The first cam assembly may be similar or equivalent to the third cam assembly wherein the third cam assembly may have a flange defining a recess couplable with a hook, the fifth cam assembly may have a flange defining a recess couplable with a hook, and the seventh cam assembly may have a flange defining a recess couplable with a hook. The second cam assembly may be similar or equivalent to the fourth cam assembly wherein the fourth cam assembly may have a flange defining a recess couplable with a hook, the sixth cam assembly may have a flange defining a recess couplable with a hook, and the eighth cam assembly may have a flange defining a recess couplable with a hook.

The compressible connector may be a) a spring, b) a rod, or c) a spring or rod coupled to an upper portion of a connector and a spring or rod coupled on one end to a lower portion of a connector, wherein the spring or rod coupled to the upper portion of the connector may be nonparallel to the spring or rod coupled to the lower portion of the connector, and wherein a spring or rod coupled to a lower portion of a connector may be coupled on an opposite end to a flange bolted to an adjacent cam assembly. Stop brace support may be coupled to a support rod that may extend along part of the height or the entire height of the distance from the highest cam-stop assembly or cam assembly to the ground. 
     Method of Sealing Garage Doors 
     Since one or more of the cam assemblies or cam-stop assemblies are fastened to a door panel hinge, then the vertical movement of the garage door panels, actuated by mechanisms known in the art for raising or lowering a garage door, will cause the lowering or raising of the plurality of cam assemblies or plurality of cam-stop assemblies. 
     To seal the garage door, the stop of the cam-stop assembly is first positioned above the stop brace. The garage door, and also the cam-stop assembly, is lowered. Referring to  FIG.  3   , when the stop of the cam-stop assembly comes into contact with the stop brace, which in the preferred embodiments would be a stop coupled to a corner of a triangular hinge of the cam stop assembly that projects towards the interior portion of the garage space—and preferably the other two corners of the cam-stop assembly are substantially parallel, at the beginning, to the main face of the garage door. When the stop of the cam-stop assembly frictionally and detachably couples with the stop brace, then torque is exerted on the cam-stop assembly such that the other two corners of the cam-stop assembly are rotated counter-clockwise, from the perspective of someone standing next to the center, front of the garage door and facing the first cam-stop assembly (which is aligned on the right side of the garage door), and thereby nudging the door panel hinge and corresponding side of the garage door approximately two inches (in some preferred embodiments), which is lower and more forward than before the stop engaged with the stop brace. The vertical position of the stop brace may be lowered or raised; in some embodiments, the stop brace may have a threaded end, and the rotation of the stop brace may raise or lower the distance between the stop brace and a stop brace support, which may be threadedly coupled to the stop brace. By nudging the door panel hinge forward and downward, the portions of the garage door may form a snug seal with the side of the door jamb and also the bottom floor. Weather stripping may be installed along the jamb, and the garage door may then be pressed against the weather stripping. 
     When the garage door is opened by the open-closing mechanism then the cam-stop assembly will also press against the stop brace, but since the garage door is being raised, then the torque and rotation of the cam-stop assembly will result in the upper portion of the cam-stop assembly being rotated towards the ceiling of the garage space, thereby causing the garage door to be moved backwards and upwards, which may have advantageously reduce the incidence of the garage door scraping against the garage door jamb (or weather stripping attached to the door jamb). 
     The linking assemblies, such as the tensible rod, that may be used to connect a cam stop assembly to one or more lower cam assemblies, may act to stabilize the cam assemblies, and also allow for the cam assemblies to move in conjunction with the cam-stop assembly, such that when the cam-stop assembly is being rotated by the torque created by force generated by the stop against the stop brace, then the other cam assemblies aligned along the same side of the garage door move in conjunction. 
     Referring to  FIG.  3   , spring  300  may couple a cam assembly, such as cam assembly  110   a,  to a connector  400 , thereby stabilizing the cam assembly. The connection of the linking assembly  600  via a tension rod coupled to a rod and bracket at rotational point  500  assists with the stabilization. A brace plate  511  may be used as an adaptor, such as a brace plate having a hole, for coupling a spring to a linking assembly, such as via a holder. The brace plate  113  may be coupled to a cam assembly. The castor wheel may be offset from axle of the adjacent cam assembly or cam-stop assembly. 
     Referring to  FIG.  7   c   , panel pivot axle  117  may be offset from cam linkage axle  119 .
