CROSS-REFERENCE TO RELATED APPLICATION(S) 
     This application claims the benefit of U.S. Provisional Patent Application No. 60/999,782, filed on Oct. 18, 2007, the entire content of which is incorporated herein by reference. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates generally to bags for transporting camera lenses, and more particularly, to a wearable camera lens bag that is ergonomic and functional while allowing a photographer to express his or her sense of style through the bag. The present invention also relates to a computer case for protecting and transporting a portable computer while also allowing the user to express his or her sense of style through the case. 
     BACKGROUND OF THE INVENTION 
     Traditional camera lens bags are generally bulky and made of a rigid material to keep the lenses protected from various environmental factors as well as to keep the lenses from breaking during their transportation. Such traditional lens bags, although used to transport the lenses to and from a photo shoot location, are generally not worn during the photo shoot due to their bulkiness and, to some, their unappealing appearance. Rather, the bags are left behind in a particular spot, and the photographer walks back and forth to and from the bag when a change of lens is desired. 
     With respect to their appearance, many traditional lens bags are made of dark, monochromatic colors that fail to reflect a photographer&#39;s personal style. Due to the highly visual profession to which the photographer belongs, it is often important that the clothing and accessories used by the photographer, including the camera lens bag, project the photographer&#39;s sense of style. 
     The photographer may also want to change the look of the bag to coordinate with his or her outfit, based on his or her mood or occasion, and/or to cater to certain types of clientele. Traditional lens bags, however, cannot be changed in terms of their look except by adding different accessories to the bag. 
     Accordingly, what is desired is a wearable camera lens bag that is ergonomic and functional, while allowing the photographer to express his or her sense of style through the bag. 
     Laptop computer bags also exist in the prior art for transporting laptop computers and other paraphernalia associated with such computers. Such bags are often bulky due to padding incorporated into the bag for protecting the computer from damage. The many compartments and pockets provided on many traditional bags or transporting laptop accessories also add to their bulkiness. Because of this, laptop bags are many times just as heavy as the laptop computer, making the transportation of laptop computers cumbersome and tiring for many. Traditional laptop bags are also often made of dark, monochromatic colors that fail to reflect a user&#39;s personal style. 
     Accordingly, what is also desired is a case for portable computers that provides protection to the computers with minimal bulk while also allowing the case to be easily transformed into a carrier that can be used to transport the case while allowing a user to reflect his or her mood or style through the case.

     DETAILED DESCRIPTION 
     According to an embodiment of the present invention, a wearable camera lens bag is provided which is designed to be worn comfortably over the shoulder during a photo shoot. According to another embodiment of the invention, the straps of the bag may be adjusted to allow the bag to be worn across the chest as a messenger bag. Wearing the bag in either mode permits quick and easy access to camera lenses. The wearer is able to reach down into the bag and remove a lens or place it back into the bag in one fluid motion. 
     According to one embodiment of the invention, the bag has an ergonomic shape that hugs the body when properly worn, and distributes the weight of the bag around the waist and/or hip of the wearer. The size, material, and thinness of the bag contribute to the ergonomic shape. Such ergonomic shape allows the wearer to feel sleek and mobile when wearing the bag instead of clumsy and bulky. The slim design also allows the bag to fold flat when not in use for easy transportation and storage. 
       FIGS. 1 and 2  are respectively front and back perspective views of a wearable camera lens bag  10  according to one embodiment of the invention. According to one embodiment, the bag  10  is made of a lightweight, wetsuit-grade neoprene material aimed to protect the camera lenses during their transportation and use, and further protect the lenses from the environment. The exterior of the bag is made of textured neoprene for abrasion resistance. The interior of the bag is made of basic, non-textured neoprene. Together, the neoprene material may be provided having various thicknesses to provide padding to the contents of the bag. Because neoprene alone is used according to one embodiment for providing the padding, the bag remains flexible to wrap around the body of the wearer when in use. 
     The neoprene material is also stretchable and has a springy, elastic consistency which provides a snug fit for the contents of the bag. The elastic properties of the neoprene are invoked for allowing the neoprene material to stretch to be conformable to the shape of a camera lens or other items in the bag so that the lens or the other items are held snugly within a pocket of the bag  10  to prevent them to fall out even as the wearer moves about rapidly and in various positions during a photo shoot. Alternatively, the bag  10  may be constructed of any other suitable material having the properties described above. 
     According to one embodiment of the invention, the bag  10  includes a first pouch assembly  11   a  and a second pouch assembly  11   b  coupled to the first pouch assembly  11   a . Alternatively, the bag  10  may include only one pouch assembly, or the bag  10  may include three or more pouch assemblies coupled to each other. Each of the pouch assemblies  11   a ,  11   b  has an upper edge  30 , a lower edge  31 , and two side edges  32  spaced from each other. The two side edges  32  extend between and are substantially perpendicular to the upper edge  30  and the lower edge  31 . For example, in the embodiment illustrated in  FIGS. 1 and 2 , each of the pouch assemblies  11   a ,  11   b  is substantially rectangular in shape. 
     Further, with reference to  FIGS. 4 and 5 , the first pouch assembly  11   a  includes a first panel  13   a  and a second panel  15   a  sewn or otherwise joined together at the lower edge  31  and at the two side edges  32  without any intervening bottom or side panels. This allows the panels to lie flat against each other when the pockets are empty. Similarly, the second pouch assembly  11   b  includes a first panel  13   b  and a second panel  15   b  sewn or otherwise joined together at the lower edge  31  and at the two side edges  32 . The upper edges of the first panel  13   a ,  13   b  and second panel  15   a ,  15   b  are not sewn together to allow receipt of camera lenses and other paraphernalia into the space created between the first and second panels. According to one embodiment, the space is divided into one or more pockets sized for snugly holding camera lenses or other items in place. Specifically, the first panels  13   a ,  13   b  and the second panels  15   a ,  15   b  on either side of the pockets are stretchable to conform to the shape of the lens or other item to snugly hold the lens or other item in place. 
     According to one embodiment of the invention, the bag  10  includes six individual pocket compartments  12   a ,  12   b : three front pockets  12   a  in the first pouch assembly  11   a  and three back pockets  12   b  in the second pouch assembly  11   b . The three front pockets  12   a  are defined via stitching  28   a  ( FIG. 1 ) that measures, for example, approximately 7 inches (17.8 cm) in length from the bottom of the bag  10 . Alternatively, the stitching  28   a  may stop short of the bottom of the bag  10 . Also, the stitching  28   a  may be a continuous line of attachment or the stitching  28   a  may be intermittent approximately along the lines shown in  FIG. 1 . According to one embodiment, the stitching does not continue to the top of the bag. Instead, there is a spacing of approximately 2 inches (5.1 cm) from the top of the bag and the stitching  28   a . Ripstop tape may be used to reinforce the stitching  28   a  so that it does not tear during use. According to one embodiment, stitching  28   b  for the three back pockets  12   b  is similar or the same as the stitching  28   a  for the front pockets  12   a . Alternatively, the stitching  28   a ,  28   b  may be any other suitable line of attachment connecting the first panel(s) to the second panel(s) to divide one or more of the pouch assemblies into a plurality of pockets for receiving camera lenses or other items. 
     In one embodiment, the first pouch assembly  11   a  is coupled to the second pouch assembly  11   b  by joining the second panels  15   a ,  15   b  to one another at the upper edge  30  with, for example, LYCRA binding (LYCRA is a registered trademark of Invista North America S.A.R.L. Corporation). Additionally, the lower edges  31  of the first and second pouch assemblies  11   a ,  11   b  may be sewn together so that the two pouch assemblies  11   a ,  11   b  are continuously or intermittently joined together along all or a portion of the lower edges  31 . According to one embodiment, the first and second pouch assemblies  11   a ,  11   b  are sewn together via stitchings  50   a ,  50   b  ( FIG. 5 ) which extend in length over a portion of stitchings  28   a ,  28   b . Further, in another embodiment, the side edges  32  of the two pouch assemblies  11   a ,  11   b  may be continuously or intermittently sewn together along all or a portion of the side edges  32  on the inside or outside. For example, the second panel  15   a  of the first pouch assembly  11   a  may be joined to the second panel  15   b  of the second pouch assembly  11   b  at one or both of the two side edges  32 . 
     According to one embodiment, each of the panels  13   a ,  13   b ,  15   a ,  15   b  has a generally rectangular shape having a width of approximately 17.25 inches (43.8 cm), a height of approximately 9.25 inches (23.5 cm), and a thickness of approximately 0.12 inches (3 mm). These four panels contribute a total of 12 mm to the thickness of the bag, providing the slim and ergonomic design of the bag. Alternatively, other embodiments of the bag may have panels having other suitable shapes and sizes. Further, in one embodiment, the bag  10  includes a stiffener between the first and second pouch assemblies  11   a ,  11   b . The stiffener adds rigidity to the bag  10  that allows the top edge of the panels from collapsing to the bottom edge while still providing the flexibility for allowing the bag to wrap around the waist of the wearer. The stiffener may be formed of a sheet of plastic material having a height and a width substantially equal to those of the panels, and a thickness of approximately 0.008 inches (0.2 mm). Any other materials that allow the bag to substantially hug the waist of the wearer are also contemplated for the stiffener. 
     As is illustrated in  FIG. 6 , the front pockets  12   a  are preferably configured to store lenses while the back pockets  12   b  that are against a wearer&#39;s body may be used to store smaller camera components and other miscellaneous materials such as, for example, flashcards, batteries, phones, and the like. In this regard, the openings of the back pockets  12   b  may be held closed via fasteners  14  (see  FIG. 2 ) to prevent the smaller components from falling out. The fasteners  14  may be snaps, or alternatively, hook and loop fasteners, magnetic fastening devices, or any other suitable device for holding the openings of the back pockets  12   b  in a closed position. Of course, if desired, the back pockets  12   b  may also be used to store some types of lenses. 
     According to one embodiment of the invention, the front pockets  12   a  and the back pockets  12   b  have substantially the same dimensions. Specifically, according to one embodiment, the centermost front and back pockets  12   a ,  12   b  are approximately 6 inches (15.2 cm) wide and approximately 4 inches (10.2 cm) deep, while the outermost front and back pockets  12   a ,  12   b  are approximately 5.5 inches (14.0 cm) wide and approximately 4 inches (10.2) deep. These approximate dimensions, as well as the flexible/moldable neoprene material used and other described configurations of the bag  10 , allow the bag  10  to ergonomically wrap around the waist of a person when worn, distributing the weight around the waist of the wearer. That is, as shown in the picture of  FIG. 8 , the outermost pockets each respectively rest against the front and back of a wearer&#39;s torso, while the center pocket rests against the side hip. 
     The front pockets  12   a  have a snug bottom (see  FIG. 5 ) and an extendible open top (see  FIG. 4 ) to accommodate a lens with a wider hood. In this regard, two elastic strips  24  (also referred to as lens extenders) are sewn inside the bag  10  at the boundaries of the centermost front pocket  12   a  and the two outermost front pockets  12   a  above the stitchings  28   a , as is illustrated in  FIG. 4 . In one embodiment, each of the elastic strips  24  is approximately 2 inches (5.1 cm) long and approximately 1.5 inches (3.8 cm) wide. According to one embodiment of the invention, the elastic strips  24  are pinched at the bottom to ensure that the front pockets  12   a  remain snug at the bottom. Thus, when the lenses are pushed all the way inside and down into the pocket, the springy, stretchable consistency of the neoprene material allows the neoprene to act as a glove that conforms to the shape of the lenses and keeps the lenses snugly in place, preventing them from falling out despite the motion of the wearer during a photo shoot, while at the same time accommodating the wide hood of some lenses via the lens extenders  24 . That is, the snug bottom along with the neoprene material that stretches to receive the lens and then retracts to exert a compressive force on the lens allows the lens to be snugly held in place within the pocket. For example, the panels  13   a ,  15   a  of the first pouch assembly  11   a  are conformable to the shape of a camera lens or other item such that the lenses or other items are held snugly within one or more of the pockets  12   a . In other embodiments, the back pockets  12   b  may also include elastic strips (lens extenders) similar to the elastic strips  24  described above with respect to the front pockets  12   a.    
     Further, the pouch assemblies  11   a ,  11   b  are conformable such that a lens or other item can be held snugly within one or more of the pockets  12   a ,  12   b  because the first panels  13   a ,  15   a  are joined directly to the second panels  13   b ,  15   b  without any intermediate panels therebetween. That is, as shown in  FIGS. 4 and 5 , the pouch assemblies  11   a ,  11   b  do not have any bottom panel or side panels. For this reason, the first panels  13   a ,  15   a  are held close to the second panels  13   b ,  15   b  where they are respectively joined, thus providing a snug fit to a camera lens or other item in one of the pockets  12   a ,  12   b  defined by each pair of a first panel and a second panel. Additionally, because the first panels  13   a ,  15   a  are joined directly to the second panels  13   b ,  15   b  without any intermediate panels therebetween, the bag  10  is adapted to lie substantially flat when all of the pockets  12   a ,  12   b  are empty. This is advantageous for efficient storage or transportation of the bag  10 . 
     The bag  10  further includes a shoulder strap  16  tied at a first end of the bag and attached to a second end via a shoulder strap clip  18 . The shoulder strap  16  may be formed of nylon or any other suitable material and may have any suitable length and width, such as 36 inches (91 cm) and 1.5 inches (3.8 cm), respectively, in one embodiment. According to one embodiment of the invention, a metal O-ring  26  attached to the second end of the bag receives the shoulder strap clip  18 . Alternatively, as is illustrated in  FIGS. 1 and 2 , the shoulder strap clip  18  and the metal O-ring  26  may be attached at opposite ends of the bag. The metal O-ring  26  may also be used to attach other components, such as, for example, keys, flashcards, other clips, and the like. According to one embodiment, the shoulder strap  16  includes an adjuster for adjusting the length of the shoulder strap  16 . 
     According to one embodiment of the invention, the bag  10  includes an interchangeable cover or flap  20  which is removably attached to a top portion of the bag via any fastening mechanism known in the art, such as, for example, a hook and loop fastening device  22  such as a VELCRO strip (VELCRO is a registered trademark of Velcro Industries). For example, the cover or flap  20  may be removably attached to one side of the second panel  15   b  of the second pouch assembly  11   b . The cover or flap  20  may alternatively be attached to the second panel  15   a  of the first pouch assembly  11   a  or the first panel  13   b  of the second pouch assembly  11   b.    
     The cover  20  provides an extra layer of protection and functionality to the bag. That is, the cover  20  folds over at least the top of the first pouch assembly  11   a  and covers the openings of the front pockets  12   a , protecting the lenses from dust, precipitation, and other environmental factors. That is, the cover  20  folds over the top and the openings of the first pouch assembly  11   a  and hangs adjacent one side of the assembly when the bag is in a closed position. The flap  20  is then lifted open to access the contents of the front pockets  12   a . Furthermore, the soft, non-textured neoprene inside of the cover allows the cover  20  to be removed and used to clean the lens, or as a blanket that covers the lens. 
     According to one embodiment, the cover  20  is substantially square in shape having sides of approximately 13 inches (33 cm) and a thickness of approximately 0.12 inches (3 mm). The VELCRO strip or other fastening device  22  may extend the entire width at or near one edge of the cover  20  or the fastening device may be located in more than one location on the cover. The cover  20  may also include edging, such as grosgrain ribbon, on the three edges not having the fastening device  22 . According to alternative embodiments, the cover  20  may also include pockets sized for accessories such as phones, business cards, and other lightweight items. 
     According to one embodiment of the invention, the removability of the cover allows the look of the bag to be easily changed to cater to a particular style, mood, or occasion. That is, the bag  10  and its wearer may project different images for different occasions by simply interchanging the existing cover  20  with a different cover. 
     According to one embodiment of the invention, various covers having different colors and patterns are provided for allowing an existing cover to be replaced with a different cover. Specifically, an existing cover  20   a  is detached from the bag  10 , and a cover  20   b  having a different color and/or pattern is attached to the bag via the fastening mechanism, as is illustrated in  FIG. 7 . The varying covers allow the photographer to project a desired image, and to change such image as often as needed. 
     Although the above embodiments have been described in terms of a camera lens bag, a person of skill in the art should recognize that the ergonomic wearable bag may be used for transporting other goods as will be apparent to a person of skill in the art. 
     According to another embodiment of the invention, the neoprene material described above with references to the camera lens bag is used to create a snug-fitting laptop sleeve that protects the laptop or other portable electronic device from dents, scratches, and the like, with minimal bulk. The neoprene material is preferably a textured neoprene for extra durability. However, a non-textured neoprene may also be used. 
     The sleeve with the laptop computer may be easily inserted into a briefcase or other bag for transporting the laptop without requiring a separate, traditional, laptop bag, while also allowing the laptop to be protected during the transportation. According to one embodiment of the invention, the laptop sleeve is also easily transformed into a shoulder bag for convenient, non-bulky transportation of laptops. In this regard, the sleeve provides a low-profile attachment mechanism for attaching a shoulder strap to the sleeve if the sleeve is to function as a non-bulky shoulder bag. When the strap is removed, the bag returns to function as a sleeve. 
       FIG. 9  is a perspective view of the front of a laptop sleeve with shoulder straps attached according to one embodiment of the invention. In the illustrated embodiment, the laptop sleeve  200  is constructed with at least two neoprene panels that have substantially the same height and length as a laptop computer that is to be inserted into the sleeve. According to one embodiment of the invention, at least one of the panels stretches to receive the laptop computer and snugly holds the computer within the sleeve. According to one embodiment of the invention, the configuration of the sleeve leaves no room for the computer to slide around within the sleeve. 
     The sleeve  200  includes metal O-rings  202   a ,  202   b  for transforming the sleeve into a shoulder bag. In this regard, a shoulder strap  204  attaches to the hooks  202   a ,  202   b  via clips  205   a ,  205   b  and allows the sleeve to be carried over the shoulder or across the chest of the wearer in a messenger-bag style. When the shoulder strap is removed, the bag returns to be a sleeve  200 , and may be carried as a notebook or inserted into another bag for transportation. 
     The sleeve  200  further includes a pocket on each of two exterior panels that form the body of the sleeve, and spans the width of the sleeve.  FIG. 9  show one such exemplary pocket  206   a.    
     As with the camera lens bag embodiment, the sleeve has minimum thickness which allows the sleeve to lay flat when empty. Thus, unlike a traditional bulky laptop bags, the sleeve according to the present embodiment has a slim design for easy transportation and storage. 
     Although this invention has been described in certain specific embodiments, those skilled in the art will have no difficulty devising variations which in no way depart from the scope and spirit of the present invention. It is therefore to be understood that this invention may be practiced otherwise than is specifically described. Thus, the present embodiments of the invention should be considered in all respects as illustrative and not restrictive, the scope of the invention to be indicated by the appended claims and their equivalents rather than the foregoing description.
