     BACKGROUND 
     Conventionally, a portable electronic device has a housing that encases the various electrical components of the portable electronic device. Often, the portable electronic device has a display arrangement that includes various layers. The various layers usually include at least a display technology layer, and may additionally include a sensing arrangement (e.g., touch sensors or touch screen) and/or a cover window disposed over the display technology layer. The cover window can be a plastic or glass cover that provides a protective outer surface that protects the display technology layer. The cover window can form part of an outer surface for the housing of the portable electronic device. Conventionally, supporting or securing the cover window to other portions of the housing tends to impede usage of a peripheral area of the cover window. 
     Unfortunately, however, as portable electronic devices continue to be made smaller, thinner, and/or more powerful, there remains a continuing need to provide improved techniques and structures for supporting cover windows of portable electronic device housings. 
     SUMMARY 
     The invention pertains to an electronic device having an enclosure formed from at least one glass cover and a peripheral structure formed adjacent the periphery of the glass cover. The peripheral structure can be secured adjacent to the glass cover with an adhesive. The peripheral structure can be molded adjacent the glass cover so that a gapless interface is formed between the peripheral structure and the periphery of the glass cover. In one embodiment, the peripheral structure can include at least an inner peripheral structure and an outer peripheral structure. The enclosure for the electronic device can be thin yet be sufficiently strong to be suitable for use in electronic devices, such as portable electronic devices. 
     The invention can be implemented in numerous ways, including as a method, system, device, or apparatus. Several embodiments of the invention are discussed below. 
     As an electronic device enclosure, one embodiment can, for example, include at least a glass cover for a top surface for the electronic device enclosure, an adhesive deposited around a periphery of the glass cover, and a peripheral structure for providing a support surface for the glass cover and for providing side protective surfaces for the glass cover. The peripheral structure is at least partially secured to the glass cover by the adhesive. 
     As a method for assembling an electronic device, one embodiment of the method can, for example, include at least: obtaining a glass member having a top surface and a bottom surface, the top surface providing an outer surface for substantially all of a surface of the electronic device; depositing an adhesive layer around a periphery of the bottom surface of the glass member; aligning the glass member relative to a support structure for the electronic device; and molding a peripheral protective side portion for the electronic device, the peripheral protective side portion being molded adjacent the periphery of the glass member, adjacent the adhesive layer, and adjacent the support structure. 
     As a method for assembling an electronic device, one embodiment of the method can, for example, include at least: obtaining a glass member having a top surface and a bottom surface, the top surface providing an outer surface for substantially all of a surface of the electronic device; attaching an internal periphery member to a periphery of the bottom surface of the glass member; and molding an outer periphery member adjacent a periphery of the glass member and adjacent the internal periphery member.

     DETAILED DESCRIPTION 
     Embodiments are described herein in the context of a housing for an electronic device. The housing can make use of an outer member, which can be formed of glass. The outer member can be aligned, protected and/or secured with respect to other portions of the housing for the electronic device. The electronic device can be portable and in some cases handheld. 
     According to one aspect, the invention pertains to an electronic device having an enclosure formed from at least one glass cover and a peripheral structure formed adjacent the periphery of the glass cover. The peripheral structure can be secured adjacent to the glass cover with an adhesive. The peripheral structure can be molded adjacent the glass cover so that a gapless interface is formed between the peripheral structure and the periphery of the glass cover. In one embodiment, the peripheral structure includes at least an inner peripheral structure and an outer peripheral structure. 
     The following detailed description is illustrative only, and is not intended to be in any way limiting. Other embodiments will readily suggest themselves to skilled persons having the benefit of this disclosure. Reference will now be made in detail to implementations as illustrated in the accompanying drawings. The same reference indicators will generally be used throughout the drawings and the following detailed description to refer to the same or like parts. It should be appreciated that the drawings are generally not drawn to scale, and at least some features of the drawings have been exaggerated for ease of illustration. 
     In the interest of clarity, not all of the routine features of the implementations described herein are shown and described. It will, of course, be appreciated that in the development of any such actual implementation, numerous implementation-specific decisions must be made in order to achieve the developer&#39;s specific goals, such as compliance with application and business related constraints, and that these specific goals will vary from one implementation to another and from one developer to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking of engineering for those of ordinary skill in the art having the benefit of this disclosure. 
     Embodiments of the invention can relate to apparatuses, systems, and methods for forming a housing having a thin glass member for an electronic device. In one example, the glass member may be an outer surface of an electronic device. The glass member may for example correspond to a glass cover that helps form part of a display area of an electronic device (i.e., situated in front of a display either as a separate part or integrated within the display. Alternatively or additionally, the glass member may form a part of the housing. For example, it may form an outer surface other than in the display area. 
     The apparatuses, systems, and methods for improving strength of thin glass are especially suitable for glass covers, or displays (e.g., LCD displays), assembled in small form factor electronic devices such as handheld electronic devices (e.g., mobile phones, media players, personal digital assistants, remote controls, etc.). The glass can be thin in these small form factor embodiments, such as less than 3 mm, or more particularly between 0.5 and 2.5 mm, or even more particularly between 0.3 and 1.0 mm. The apparatuses, systems, and methods can also be used for glass covers or displays for other devices including, but not limited to, relatively larger form factor electronic devices (e.g., portable computers, tablet computers, displays, monitors, televisions, etc.). The glass can also be thin in these larger form factor embodiments, such as less than 5 mm, or more particularly between 0.5 and 3 mm, or even more particularly between 0.3 and 2.0 mm. 
     Embodiments are discussed below with reference to  FIGS. 1-7C . However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes as the invention extends beyond these limited embodiments. 
       FIG. 1  is a flow diagram of a housing formation process  100  according to one embodiment of the invention. The housing formation process  100  can operate to produce a housing for an electronic device, or at least a portion of such a housing. 
     The housing formation process  100  can initially obtain  102  a glass member. The glass member is to serve as a significant outer surface for the housing. For example, the glass member can correspond to a top surface for the housing. Alternatively or additionally, the glass member can correspond to a bottom surface for the housing. The glass member is typically thin, particularly when used with portable electronic devices. In one embodiment, the glass member has a thickness of less than 5 mm, or more particularly less than 1 mm. 
     After the glass member has been obtained  102 , an adhesive can be deposited  104  around a periphery of a bottom surface of the glass member. The glass member has a top surface that can represent an outer surface for the housing, and a bottom surface that is an inner surface that is not exposed. In one embodiment, the adhesive being deposited  104  can be a thermally activated adhesive. The adhesive can, for example, be provided as film or as a layer. Also, the manner by which the adhesive is deposited can vary. In one implementation, the adhesive can be deposited  104  by forming a ring-like pattern of adhesive that can be placed around the periphery of the bottom surface of the glass member. In another implementation, the adhesive can be screen printed onto the periphery of the bottom surface of the glass member. 
     Thereafter, the glass member can be aligned  106  relative to a support structure. The support structure can be provided as being a component of the housing for the electronic device. For example, the support can pertain to a side structure for the housing or an interior support member. After the glass member has been aligned  106  with the support structure, a peripheral protective side portion can be molded  108  adjacent to the periphery of the glass member and adjacent to the adhesive. The adhesive can serve to secure the peripheral protective side member to the glass member. The peripheral protective side member being molded  108  can also be formed adjacent the support structure. Typically, the peripheral side portion would also be secured to the support structure by chemical bonding and/or mechanical features (e.g., undercuts or interlocks). In such case, the glass member and the peripheral protective side member are secured to the support structure and thus form at least a portion of the housing for the electronic device. Also, if the adhesive is thermally activated, the molding  108  can also serve to activate the thermally activated adhesive so that a strong bond can be provided to the glass member and the peripheral protective side member. 
       FIG. 2A  is a cross-sectional view of an electronic device housing  200  according to one embodiment. The electronic device housing  200  includes an outer housing member  201  supported and protected by a protective side member  202 , the protective side member  202  being positioned tightly adjacent sides of the outer housing member  201 . The protective side members  202  can provide a thin layer of material positioned tightly adjacent sides of the outer housing member  201 , thereby buffering impact at the sides of the outer housing member  201 . The protective side member  202  also supports the outer housing member  201  and serves to secure the outer housing member  201  to other portions of the electronic device housing  200 . In one embodiment, the protective side member  202  extends around all sides of the outer housing member  201 . In another embodiment, the protective side member  202  extends around those of the sides of the outer housing member  201  that would otherwise be exposed. 
     As shown in  FIG. 2A , the outer housing member  201  can be secured to a support structure  204  of the electronic device housing  200 . The support structure  204  can, for example, be an outer periphery member for the electronic device housing  200 . In one embodiment, the support structure  204  can couple to another outer housing member  206 , which can be formed differently than the outer housing member  201 . 
     The protective side member  202  can be secured tightly adjacent the sides of the outer housing member  201  using an adhesive  208 . In one embodiment, the adhesive  208  can be applied as a layer of adhesive that is provided around a periphery of an inner side of the outer housing member  201 . The protective side member  202  can also be molded in place so as to be tightly adjacent the sides of the outer housing member  201 . By molding the protective side member  202  in place, the outer exposed interface  210  between the sides (e.g., edges) of the outer housing member  201  and the peripheral side member  202  is essentially gap-free. The protective side member  202  can also be molded against the adhesive  208  deposited on the periphery of the bottom side of the outer housing member  201 . The adhesive  208  can thus serve to secure the protective side member  202  against the sides of the outer housing member  201 . Also, if the adhesive  208  is thermally activated, the molding of the protective side member  202  can also serve to activate the thermally activated adhesive  208  so that a strong bond can be provided to the outer housing member  201  and the peripheral protective side member  202  via the adhesive  208 . An internal space  212  is provided internal to the electronic device housing  200  whereby various electrical components can be attached, affixed or placed so as to provide electronic operations for the electronic device. 
     The various members, parts or assemblies of the electronic device housing  200  can be formed of any of a variety of materials, e.g., glass, polymers or metal. In one embodiment, the outer housing member  201  is glass, the protective side member  202  is be formed from polymer (e.g., thermoplastic), the support structure  204  is formed from metal or polymer (e.g., plastic), and the another outer housing member  206  is formed from glass, polymer (e.g., plastic) or metal. More particularly, in some embodiments, the protective side member  202  can be a structurally strengthened polymer (e.g., thermoplastic). As an example, the protective side member  202  can be polymer, such as polyarylamide, nylon or polycarbonate, which can be structurally strengthened by including glass fibers. For example, some examples of some structurally strengthened polymers include 50% glass filled nylon and 30% glass filled polycarbonate. 
       FIG. 2B  is a cross-sectional assembly diagram for the electronic device housing  200  shown in  FIG. 2A , according to one embodiment. The outer housing member  201  has a top surface  214  and a bottom surface  216 . The bottom surface  216  of the outer housing member  201  has adhesive  208  applied as a layer of adhesive that is provided around a periphery of the bottom surface  216  of the outer housing member  201 . The protective side member  202  can then be molded adjacent the sides of the outer housing member  201 . When the protective side member  202  is molded, the protective side member  202  is also at least partially formed adjacent the adhesive  208  on the bottom surface  216  of the outer housing member  201 . Moreover, when the protective side member  202  is formed, the protective side member  202  can also be adjacent and secured to an upper side portion  218  of the support structure  204 . When the protective side members  202  are provided at the sides (i.e., edges) of the outer housing member  201 , the protective side member  202  provides a buffer layer (e.g., bumper) that dampens impact induced at the sides of the outer housing member  201  of the electronic device housing  200 . 
       FIG. 2C  is a cross-sectional view of an electronic device housing  220  according to one embodiment. The electronic device housing  220  includes a first outer housing member  201  supported and protected by a first protective side member  202 . The first protective side member  202  is positioned tightly adjacent sides of the first outer housing member  201 . The first protective side member  202  also supports the first outer housing member  201  and serves to secure the first outer housing member  201  to other portions of the electronic device housing  220 . In this embodiment, the first protective side member  202  is secured to not only the first outer housing member  201  but also a support structure  204 . The support structure  204  may be an outer periphery member for the electronic device housing  220 . 
     The first protective side member  202  can be secured tightly adjacent the sides of the outer housing member  201  using the adhesive  208 . In one embodiment, the adhesive  208  can be applied as a layer of adhesive that is provided around a periphery of an inner side of the first outer housing member  201 . The first protective side member  202  can also be molded in place so as to be tightly adjacent the sides of the first outer housing member  201 . By molding the first protective side member  202  in place, the outer exposed interface  210  between the sides (e.g., edges) of the outer housing member  201  and the protective side member  202  is essentially gap-free. The first protective side member  202  can also be molded against the adhesive  208  deposited on the periphery of the bottom side of the first outer housing member  201 . The adhesive  208  can thus serve to secure the first protective side member  202  against the sides of the outer housing member  201 . Also, if the adhesive  208  is thermally activated, the molding of the first protective side member  202  can also serve to activate the thermally activated adhesive  208  so that a strong bond can be provided to the first outer housing member  201  and the first peripheral protective side member  202  via the adhesive  208 . 
     The electronic device housing  220  can also include an internal structure  222  that is integral with or secured to the support structure  204 . In one embodiment, the internal structure  222  can be secured to an inner surface of the support structure  204  such that it is offset from front and back planar boundaries of the support structure  204  (which may be an outer periphery member). As shown in  FIG. 2C , the internal structure  222  can be secured at the mid-point of the height of the support structure  204 . A first internal space  224  is provided internal to the electronic device housing  220  whereby various electrical components can be attached, affixed or placed so as to provide electronic operations for the electronic device. 
     In this embodiment, the electronic device housing  220  can also include similar structures on an opposite side of the electronic device housing  220 . Namely, the electronic device housing  220  can further include a second outer housing member  226  supported and protected by a second protective side member  228 . The second protective side member  228  can be positioned tightly adjacent sides of the second outer housing member  226 . The second protective side member  228  also supports the second outer housing member  226  and serves to secure the second outer housing member  226  to other portions of the electronic device housing  220 . In this embodiment, the second protective side member  228  is secured to not only the second outer housing member  226  but also the support structure  204 . As previously noted, the support structure  204  may be an outer periphery member for the electronic device housing  220 . In this embodiment, the second protective side member  228  can be secured to the outer periphery member  204  on the opposite side from the first protective side member  202 . The second protective side member  228  can be secured tightly adjacent the sides of the second outer housing member  226  using an adhesive  230 . In one embodiment, the adhesive  230  can be applied as a layer of adhesive that is provided around a periphery of an inner side of the second outer housing member  226 . The second protective side member  228  can also be molded in place so as to be tightly adjacent the sides of the second outer housing member  226 . Further, a second internal space  232  is provided internal to the electronic device housing  220  (between the internal structure  222  and the second outer housing member  226 ) whereby various electrical components can be attached, affixed or placed so as to provide electronic operations for the electronic device. The second internal space  232  can be separate from or joined with the first internal space  224 . 
     In one embodiment, the first outer housing member  201  can represent a top outer surface for the portable electronic device, and the second outer surface housing member  226  can represent a bottom outer surface housing. In one embodiment, both the first outer housing member  201  and the second outer housing member  226  are glass (e.g., glass covers). 
       FIG. 3A  is a cross-sectional view of an electronic device housing  300  according to one embodiment. The electronic device housing  300  includes an outer housing member  301  supported and protected by a protective side member  302 , the protective side member  302  being positioned tightly adjacent sides of the outer housing member  301 . The protective side members  302  can provide a thin layer of material positioned tightly adjacent sides of the outer housing member  301 , thereby buffering impact at the sides of the outer housing member  301 . The protective side member  302  also supports the outer housing member  301  and serves to secure the outer housing member  301  to other portions of the electronic device housing  300 . In one embodiment, the protective side member  302  extends around all sides of the outer housing member  301 . In another embodiment, the protective side member  302  extends around those of the sides of the outer housing member  301  that would otherwise be exposed. 
     As shown in  FIG. 3A , the outer housing member  301  can be secured to a support structure  304  of the electronic device housing  300 . In one embodiment, as shown in  FIG. 3A , one or more securing features  305  can be provided on an upper surface of the support structure  304 . The securing features  305  can be integral with the support structure  304 . The securing features  305  (e.g., mechanical features, such as undercuts or interlocks) can be used to assist with the securing of the protective side member  302  (and thus the outer housing member  301 ) to the support structure  304 . The support structure  304  can, for example, be an outer periphery member for the electronic device housing  300 . The support structure  304  can couple to another outer housing member  306 , which can be formed differently than the outer housing member  301 . 
     The protective side member  302  can be secured tightly adjacent the sides of the outer housing member  301  using an adhesive  308 . In one embodiment, the adhesive  308  can be applied as a layer of adhesive that is provided around a periphery of an inner side of the outer housing member  301 . The protective side member  302  can also be molded in place so as to be tightly adjacent the sides of the outer housing member  301 . By molding the protective side member  302  in place, the outer exposed interface  310  between the sides (e.g., edges) of the outer housing member  301  and the peripheral side member  302  is essentially gap-free. The protective side member  302  can also be molded against the adhesive  308  deposited on the periphery of the bottom side of the outer housing member  301 . The adhesive  308  can thus serve to secure the protective side member  302  against the sides of the outer housing member  301 . Also, if the adhesive  308  is thermally activated, the molding of the protective side member  302  can also serve to activate the thermally activated adhesive  308  so that a strong bond can be provided to the outer housing member  301  and the peripheral protective side member  302  via the adhesive  308 . An internal space  312  is provided internal to the electronic device housing  300  whereby various electrical components can be attached, affixed or placed so as to provide electronic operations for the electronic device. 
     The various members, parts or assemblies of the electronic device housing  300  can be formed of any of a variety of materials, e.g., glass, polymers or metal. In one embodiment, the outer housing member  301  is glass, the protective side member  302  is be formed from polymer (e.g., thermoplastic), the support structure  304  is formed from metal or polymer (e.g., plastic), and the another outer housing member  306  is formed from glass, polymer (e.g., plastic) or metal. More particularly, in some embodiments, the protective side member  302  can be a structurally strengthened polymer (e.g., thermoplastic). As an example, the protective side member  302  can be polymer, such as polyarylamide, nylon or polycarbonate, which can be structurally strengthened by including glass fibers. For example, some examples of some structurally strengthened polymers include 50% glass filled nylon and 30% glass filled polycarbonate. 
       FIG. 3B  is a cross-sectional assembly diagram for the electronic device housing  300  shown in  FIG. 3A , according to one embodiment. The outer housing member  301  has a top surface  314  and a bottom surface  316 . The bottom surface  316  of the outer housing member  301  has adhesive  308  applied as a layer of adhesive that is provided around a periphery of the bottom surface  316  of the outer housing member  301 . The protective side member  302  can then be molded adjacent the sides of the outer housing member  301 . When the protective side member  302  is molded, the protective side member  302  is also at least partially formed adjacent the adhesive  308  on the bottom surface  316  of the outer housing member. Moreover, when the protective side member  302  is formed, the protective side member  302  can also be adjacent and secured to an upper side portion  318  of the support structure  304 . In one embodiment, as shown in  FIG. 3B , one or more securing features  305  can be provided on an upper surface of the support structure  304 . The protective side member  302  can be also molded around the one or more securing features  305 , which can further secure the protective side member  302  to the support structure  304 . When the protective side members  302  are provided at the sides (i.e., edges) of the outer housing member  301 , the protective side members  302  provide a buffer layer (e.g., bumper) that dampens impact induced at the sides of the outer housing member  301  of the electronic device housing  300 . 
       FIG. 3C  is a cross-sectional view of an electronic device housing  320  according to one embodiment. The electronic device housing  320  includes a first outer housing member  301  supported and protected by a first protective side member  302 . The first protective side member  302  is positioned tightly adjacent to the sides of the first outer housing member  301 . The first protective side member  302  also supports the first outer housing member  301  and serves to secure the first outer housing member  301  to other portions of the electronic device housing  320 . In this embodiment, the first protective side member  302  is secured to not only the first outer housing member  301  but also a support structure  304 . In addition, in this embodiment, one or more securing features  305  can be provided on an upper surface of the support structure  304 . The support structure  304  may be an outer periphery member for the electronic device housing  320 . 
     The first protective side member  302  can be secured tightly adjacent the sides of the outer housing member  301  using the adhesive  308 . In one embodiment, the adhesive  308  can be applied as a layer of adhesive that is provided around a periphery of an inner side of the first outer housing member  301 . The first protective side member  302  can also be molded in place so as to be tightly adjacent the sides of the first outer housing member  301 . By molding the first protective side member  302  in place, the outer exposed interface  310  between the sides (e.g., edges) of the outer housing member  301  and the protective side member  302  is essentially gap-free. The first protective side member  302  can also be molded against the adhesive  308  deposited on the periphery of the bottom side of the first outer housing member  301 . The adhesive  308  can thus serve to secure the first protective side member  302  against the sides of the outer housing member  301 . Also, if the adhesive  308  is thermally activated, the molding of the first protective side member  302  can also serve to activate the thermally activated adhesive  308  so that a strong bond can be provided to the first outer housing member  301  and the first protective side member  302  via the adhesive  308 . 
     The electronic device housing  320  can also include an internal structure  322  that is integral with or secured to the support structure  304 . In one embodiment, the internal structure  322  can be secured to an inner surface of the support structure  304  such that it is offset from front and back planar boundaries of the support structure  304  (which may be an outer periphery member). As shown in  FIG. 3C , the internal structure  322  can be secured at the mid-point of the height of the support structure  304 . A first internal space  324  is provided internal to the electronic device housing  320  whereby various electrical components can be attached, affixed or placed so as to provide electronic operations for the electronic device. 
     In this embodiment, the electronic device housing  320  can also include similar structures on an opposite side of the electronic device housing  320 . Namely, the electronic device housing  320  can further include a second outer housing member  326  supported and protected by a second protective side member  328 . The second protective side member  328  can be positioned tightly adjacent sides of the second outer housing member  326 . The second protective side member  328  also supports the second outer housing member  326  and serves to secure the second outer housing member  326  to other portions of the electronic device housing  320 . In this embodiment, the second protective side member  328  is secured to not only the second outer housing member  326  but also the support structure  304 . In addition, in this embodiment, one or more securing features  329  can be provided on a bottom surface of the support structure  304 . The securing features  329  can be integral with the support structure  304 . As previously noted, the support structure  304  may be an outer periphery member for the electronic device housing  320 . In this embodiment, the second protective side member  328  can be secured to the support structure  304  on the opposite side from the first protective side member  302 . The second protective side member  328  can be secured tightly adjacent the sides of the second outer housing member  326  using an adhesive  330 . In one embodiment, the adhesive  330  can be applied as a layer of adhesive that is provided around a periphery of an inner side of the second outer housing member  326 . The second protective side member  328  can also be molded in place so as to be tightly adjacent the sides of the second outer housing member  326 . Further, a second internal space  332  is provided internal to the electronic device housing  320  (between the internal structure  322  and the second outer housing member  326 ) whereby various electrical components can be attached, affixed or placed so as to provide electronic operations for the electronic device. The second internal space  332  can be separate from or joined with the first internal space  324 . 
     In one embodiment, the first outer housing member  301  can represent a top outer surface for the portable electronic device, and the second outer housing member  326  can represent a bottom outer surface housing. In one embodiment, both the first outer housing member  301  and the second outer housing member  326  are glass (e.g., glass covers). 
     Although the edges of the outer housing members ( 201 ,  226 ,  301 ,  326 ) can be square as suggested by  FIGS. 2A-3C , it should understood that the edges of the outer housing member need not be square but can be formed with other geometries, such as with chamfered (or flattened) edges or rounded edges.  FIGS. 4A and 4B  are cross-sectional views of electronic device housings according to other embodiments that are similar to the electronic device housing  200  illustrated in  FIG. 2A  but which have different edge geometries for the outer device housing. 
       FIG. 4A  is a cross-sectional view of an electronic device housing  400  according to one embodiment. The electronic device housing  400  is the same as the electronic device housing  200  illustrated in  FIG. 2A  except that the edges  410  of the outer housing member  401  have been chamfered (or flattened). Additionally, the protective side member  402  is molded against the edges of the outer housing member  401 , including the chamfered edges  410 . Hence, as with other embodiments, by molding the protective side member  402  in place, the outer exposed interface  410  between the sides (e.g., edges  402 ) of the outer housing member  401  and the protective side member  402  is essentially gap-free even though the edges of the protective side member  402  are chamfered. 
       FIG. 4B  is a cross-sectional view of an electronic device housing  420  according to one embodiment. The electronic device housing  420  is the same as the electronic device housing  200  illustrated in  FIG. 2A  except that the edges  410  of the outer housing member  401  have been rounded. Additionally, the protective side member  402  is molded against the edges of the outer housing member  401 , including the rounded edges. Hence, as with other embodiments, by molding the protective side member  402  in place, the outer exposed interface  410  between the sides (e.g., edges) of the outer housing member  401  and the protective side member  402  is essentially gap-free even though the edges of the protective side member  402  are rounded. 
       FIG. 5  is a flow diagram of a housing formation process  500  according to one embodiment. The housing formation process  500  can operate to produce a housing for an electronic device, or at least a portion of such a housing. 
     The housing formation process  500  can initially obtain  502  a glass member to be utilized with the housing for the electric device. The glass member to be utilized is a significant outer surface for the housing. For example, the glass member can correspond to a top surface for the housing. Alternatively, the glass member can correspond to a bottom surface for the housing. The glass member is typically thin, particularly when the housing being formed is for a portable electronic device. In one embodiment, the glass member has a thickness of less than 5 mm, and in another embodiment, the glass member has a thickness of less than 1 mm. 
     Next, an internal peripheral member can be attached  504  to the periphery of a bottom surface of the glass member. Typically, the internal peripheral member is attached  504  to the bottom surface of the glass member using an adhesive, though other means can be used, such as mechanical features (e.g., undercuts or interlocks). 
     Thereafter, an outer peripheral member can be formed  506 , e.g., molded, adjacent the periphery of the glass member and adjacent the inner peripheral member. The outer peripheral member provides an exposed outer surface for the housing. Specifically, the outer peripheral member provides a thin protective layer of material tightly adjacent the periphery of the glass member. The outer peripheral member can chemically bond with the inner peripheral member. Also, the inner peripheral member and/or the outer peripheral member can be secured to a support structure for the housing so that the glass member is able to be mechanically secured to the housing. 
       FIG. 6  is a flow diagram of a housing formation process  600  according to one embodiment. The housing formation process  600  can operate to produce a housing for an electronic device, or at least a portion of such a housing. 
     The housing formation process  600  can initially obtain  602  a glass member. The glass member is to serve as a significant outer surface for the housing. For example, the glass member can correspond to a top surface for the housing. Alternatively or additionally, the glass member can correspond to a bottom surface for the housing. The glass member is typically thin, particularly when used with portable electronic devices. In one embodiment, the glass member has a thickness of less than 5 mm, or more particularly less than 1 mm. 
     After the glass member has been obtained  602 , an adhesive can be deposited  604  around a periphery of a bottom surface of the glass member. The glass member has a top surface that can represent an outer surface for the housing, and a bottom surface that is an inner surface that is not exposed. In one embodiment, the adhesive being deposited  604  can be a thermally activated adhesive. Also, the manner by which the adhesive is deposited can vary. In one implementation, the adhesive can be deposited  604  by forming a ring-like pattern of adhesive that can be placed around the periphery of the bottom surface of the glass member. In another implementation, the adhesive can be screen printed onto the periphery of the bottom surface of the glass member. 
     In addition, an internal peripheral member can be placed  606  to the periphery of the glass member and adjacent the adhesive. In one implementation, the internal peripheral member can be secured to the bottom surface of the glass member using an adhesive, though other means can be used, such as mechanical features (e.g., undercuts or interlocks). The internal peripheral member can also be placed  606  by molding the internal peripheral member in place. In one embodiment, if the adhesive is thermally activated, the molding can also serve to activate the thermally activated adhesive so that a strong bond can be provided to the glass member and the internal peripheral member. 
     Thereafter, an outer peripheral member can be molded  608  over the internal peripheral member such that the outer peripheral member is formed adjacent the periphery of the glass member and adjacent the inner peripheral member. The outer peripheral member provides an exposed outer surface for the housing. Specifically, the outer peripheral member provides a thin protective layer of material tightly adjacent the periphery of the glass member. The outer peripheral member can chemically bond with the inner peripheral member. Alternatively or additionally, a thermally activated adhesive could be used between the internal peripheral member and the outer peripheral member (or between the glass member and the outer peripheral member), and the molding of the outer peripheral member in place can also serve to activate the thermally activated adhesive so that a strong bond can be provided the inner peripheral member (and/or the glass member). Also, the inner peripheral member and/or the outer peripheral member can be secured to a support structure for the housing so that the glass member is able to be mechanically secured to the housing. Typically, the peripheral members could be secured to the support structure by chemical bonding and/or mechanical features (e.g., undercuts or interlocks). 
       FIG. 7A  is a cross-sectional view of an electronic device housing  700  according to another embodiment. The electronic device housing  700  includes an outer housing member  701  supported and protected by an inner protective side member  703  and an outer protective side member  702 , the inner protective side member  703  being positioned tightly adjacent sides of the outer housing member  701 . The inner protective side member  703  can provide a thin layer of material positioned tightly adjacent sides of the outer housing member  701 , thereby buffering impact at the sides of the outer housing member  701 , the outer protective side member  702  being positioned tightly adjacent the sides of the inner protective side member  703  as well as the sides of the outer housing member  701 . The outer and inner protective side members  702 ,  703  can individually or in combination provide a thin layer of material positioned tightly adjacent sides of the outer housing member  701 , thereby buffering impact at the sides of the outer housing member  701 . 
     One or both of the inner and outer protective side members  702 ,  703  can also support the outer housing member  701  and serve to secure the outer housing member  701  to other portions of the electronic device housing  700 . In one embodiment, the outer protective side member  702  (and possibly also the inner protective side member  703 ) extends around all sides of the outer housing member  701 . In another embodiment, the outer protective side member  702  (and possibly also the inner protective side member  703 ) extends around those of the sides of the outer housing member  701  that would otherwise be exposed. 
     As shown in  FIG. 7A , the outer housing member  701  can be secured to a support structure  704  of the electronic device housing  700 . The support structure  704  can, for example, be an outer periphery member for the electronic device housing  700 . In one embodiment, the support structure  704  can couple to another outer housing member  706 , which can be formed differently than the outer housing member  701 . 
     The inner protective side member  703  can be secured tightly adjacent the sides of the outer housing member  701  using an adhesive  708 . In one embodiment, the adhesive  708  can be applied as a layer of adhesive that is provided around a periphery of an inner side of the outer housing member  701 . The adhesive  708  can thus serve to secure the inner protective side member  703  against the sides of the outer housing member  701 . The outer protective side member  702  can be molded in place around at least a portion of the inner protective side member  703  and adjacent at least a portion of the sides of the outer housing member  701  so as to be tightly adjacent the sides of the outer housing member  701 . By molding the outer protective side member  702  in place, the outer exposed interface  710  between the sides (e.g., edges) of the outer housing member  701  and the outer protective side member  702  is essentially gap-free. During the molding, the outer protective side member  703  can be chemically bonded to at least a portion of the inner protective side member  702 . Also, if the adhesive  708  is thermally activated, the molding of the outer protective side member  702  can also serve to activate the thermally activated adhesive  708  so that a strong bond can be provided to the outer housing member  701  and the inner protective side member  703  via the adhesive  708 . An internal space  712  is provided internal to the electronic device housing  700  whereby various electrical components can be attached, affixed or placed so as to provide electronic operations for the electronic device. 
     The various members, parts or assemblies of the electronic device housing  700  can be formed of any of a variety of materials, e.g., glass, polymers or metal. In one embodiment, the outer housing member  701  is glass, the protective side members  702 ,  703  can be formed from a polymer (e.g., thermoplastic), the support structure  704  can be formed from metal or polymer (e.g., plastic), and the another outer housing member  706  can be formed from glass, polymer (e.g., plastic) or metal. More particularly, in some embodiments, the inner protective side member  703  can be a structurally strengthened polymer (e.g., thermoplastic). As an example, the inner protective side member  703  can be polymer, such as polyarylamide, nylon or polycarbonate, which can be structurally strengthened by including glass fibers. For example, some examples of some structurally strengthened polymers include 50% glass filled nylon and 30% glass filled polycarbonate. 
       FIG. 7B  is a cross-sectional assembly diagram for the electronic device housing  700  shown in  FIG. 7A , according to one embodiment. The outer housing member  701  has a top surface  714  and a bottom surface  716 . The bottom surface  716  of the outer housing member  701  has adhesive  708  applied as a layer of adhesive that is provided around a periphery of the bottom surface  716  of the outer housing member  701 . The inner protective side member  703  can then be secured adjacent the sides of the outer housing member  701 . More particularly, the inner protective side member  703  can be secured to the outer protective side member  702  using the adhesive  708  on the bottom surface  716  of the outer housing member  701 . The outer protective side member  702  can be molded adjacent at least a portion of the sides of the outer housing member  701  and adjacent or over one or more sides of the inner protective side member  703 . The molding process can also lead to chemical bonding of the outer protective side member  702  and the inner protective side member  703 . 
     Moreover, when the outer protective side member  702  is formed, the outer protective side member  702  can also be adjacent and secured to an upper side portion  718  of the support structure  704 . When the outer protective side member  702  is provided at the sides (i.e., edges) of the outer housing member  701 , the outer protective side member  702  (alone or in combination with the inner protective side member  703 ) provides a buffer layer (e.g., bumper) that dampens impact induced at the sides of the outer housing member  701  of the electronic device housing  700 . 
       FIG. 7C  is a cross-sectional view of an electronic device housing  720  according to one embodiment. The electronic device housing  720  includes a first outer housing member  701  supported and protected by a first inner protective side member  703  and a first outer protective side member  702 . The first inner protective side member  703  is positioned tightly adjacent sides of the first outer housing member  701 , the outer protective side member  702  being positioned tightly adjacent the sides of the first inner protective side member  703  as well as the sides of the first outer housing member  701 . The first outer and inner protective side members  702 ,  703  can individually or in combination provide a thin layer of material positioned tightly adjacent sides of the first outer housing member  701 , thereby buffering impact at the sides of the first outer housing member  701 . 
     One or both of the first outer and inner protective side members  702 ,  703  can also support the first outer housing member  701  and serve to secure the first outer housing member  701  to other portions of the electronic device housing  720 . In one embodiment, the first outer protective side member  702  (and possibly also the first inner protective side member  703 ) extends around all sides of the first outer housing member  701 . In another embodiment, the first outer protective side member  702  (and possibly also the first inner protective side member  703 ) extends around those of the sides of the first outer housing member  701  that would otherwise be exposed. 
     The first inner protective side member  703  can be secured tightly adjacent the sides of the first outer housing member  701  using an adhesive  708 . In one embodiment, the adhesive  708  can be applied as a layer of adhesive that is provided around a periphery of an inner side of the first outer housing member  701 . The adhesive  708  can thus serve to secure the first inner protective side member  703  against the sides of the first outer housing member  701 . The first outer protective side member  702  can be molded in place around at least a portion of the first inner protective side member  703  and adjacent at least a portion of the sides of the first outer housing member  701  so as to be tightly adjacent the sides of the first outer housing member  701 . By molding the first outer protective side member  702  in place, the outer exposed interface  710  between the sides (e.g., edges) of the first outer housing member  701  and the first outer peripheral side member  702  is essentially gap-free. During the molding, the first outer protective side member  702  can be chemically bonded to at least a portion of the first inner protective side member  703 . Also, if the adhesive  708  is thermally activated, the molding of the first outer protective side member  702  can also serve to activate the thermally activated adhesive  708  so that a strong bond can be provided to the first outer housing member  701  and the first inner peripheral side member  703  via the adhesive  708 . 
     The electronic device housing  720  can also include an internal structure  722  that is integral with or secured to the support structure  704 . In one embodiment, the internal structure  722  can be secured to an inner surface of the support structure  704  such that it is offset from front and back planar boundaries of the support structure  704  (which may be an outer periphery member). As shown in  FIG. 7C , the internal structure  722  can be secured at the mid-point of the height of the support structure  704 . A first internal space  724  is provided internal to the electronic device housing  720  whereby various electrical components can be attached, affixed or placed so as to provide electronic operations for the electronic device. 
     In this embodiment, the electronic device housing  720  can also include similar structures on an opposite side of the electronic device housing  720 . Namely, the electronic device housing  720  can further include a second outer housing member  726  supported and protected by a second inner protective side member  728  and a second outer protective side member  729 . The second inner protective side member  728  can be positioned tightly adjacent sides of the second outer housing member  726 . The second outer protective side member  729  can be positioned tightly adjacent the sides of the second inner protective side member  728  as well as the sides of the second outer housing member  726 . The second outer and inner protective side members  728 ,  729  can individually or in combination provide a thin layer of material positioned tightly adjacent sides of the second outer housing member  726 , thereby buffering impact at the sides of the second outer housing member  726 . 
     One or both of the second inner and outer protective side members  728 ,  729  can also support the second outer housing member  726  and serve to secure the second outer housing member  726  to other portions of the electronic device housing  720 . In one embodiment, the second outer protective side member  729  (and possibly also the second inner protective side member  728 ) extends around all sides of the second outer housing member  726 . In another embodiment, the second outer protective side member  729  (and possibly also the second inner protective side member  728 ) extends around those of the sides of the second outer housing member  726  that would otherwise be exposed. 
     The second inner protective side member  728  can be secured tightly adjacent the sides of the second outer housing member  726  using an adhesive  730 . In one embodiment, the adhesive  730  can be applied as a layer of adhesive that is provided around a periphery of an inner side of the second outer housing member  726 . The adhesive  730  can thus serve to secure the second inner protective side member  728  against the sides of the second outer housing member  726 . The second outer protective side member  729  can be molded in place around at least a portion of the second inner protective side member  728  and adjacent at least a portion of the sides of the second outer housing member  726  so as to be tightly adjacent the sides of the second outer housing member  726 . By molding the second outer protective side member  729  in place, the outer exposed interface  731  between the sides (e.g., edges) of the second outer housing member  726  and the second outer protective side member  729  is essentially gap-free. During the molding, the second outer protective side member  729  can be chemically bonded to at least a portion of the second inner protective side member  728 . Also, if the adhesive  730  is thermally activated, the molding of the second outer protective side member  729  can also serve to activate the thermally activated adhesive  730  so that a strong bond can be provided to the second outer housing member  726  and the second inner protective side member  728  via the adhesive  730 . A first internal space  724  is provided internal to the electronic device housing  720  whereby various electrical components can be attached, affixed or placed so as to provide electronic operations for the electronic device. 
     Further, a second internal space  732  is provided internal to the electronic device housing  720  (between the internal structure  722  and the second outer housing member  726 ) whereby various electrical components can be attached, affixed or placed so as to provide electronic operations for the electronic device. The second internal space  732  can be separate from or joined with the first internal space  724 . 
     The various members, parts or assemblies of the electronic device housing  720  can be formed of any of a variety of materials, e.g., glass, polymers or metal. In one embodiment, the outer housing members  701 ,  726  are glass, the protective side members  702 ,  703 ,  728 ,  729  can be formed from a polymer (e.g., thermoplastic), and the support structures  704 ,  722  can be formed from metal or polymer (e.g., plastic). More particularly, in some embodiments, the protective side members  702 ,  703 ,  728 ,  729  can be a structurally strengthened polymer (e.g., thermoplastic). As an example, the protective side members  702 ,  703 ,  728 ,  729  can be polymer, such as polyarylamide, nylon or polycarbonate, which can be structurally strengthened by including glass fibers. For example, some examples of some structurally strengthened polymers include 50% glass filled nylon and 30% glass filled polycarbonate. 
     In one embodiment, the first outer housing member  701  can represent a top outer surface for the portable electronic device, and the second outer surface housing  726  member can represent a bottom outer surface housing. In one embodiment, both the first outer housing member  701  and the second outer housing member  726  are glass (e.g., glass covers). 
     The protective side members discussed above are typically thin layers of material positioned tightly adjacent sides of the outer housing member, thereby buffering impact at the sides of the outer housing members. In one embodiment, the protective side members are to be strong; hence, a structurally strengthened polymer, such as polyarylamide, can be utilized. The polyarylamide can be strengthened by containing glass fibers. One source of strengthened polyarylamide is IXEF polyarylamide (PARA) from Solvay Advanced Polymers, L.L.0 which can contain glass fiber reinforcement. 
     Additionally, since the protective side members are tightly adjacent sides of the outer housing member, the respective materials used for the protective side members and the outer housing member can be thermally controlled. Specifically, the Coefficient of Thermal Expansion (CTE) of the respective materials, if not controlled, can produce undesired stress on the sides of the outer housing member. For example, with an outer housing member of glass, its CTE is about 10 millimeters/meter/° C. Hence, ideally, for this example the CTE of the material for the protective side members would be about 10 millimeters/meter/° C. Although plastics tend to have CTE&#39;s (e.g., roughly 100 millimeters/meter/° C.) that are dramatically higher than that of glass, some manufactured polymers, such as polyarylamide, can have CTE&#39;s (e.g., roughly 30 millimeters/meter/° C.) that are substantially closer to that of glass and thereby would, if used, induce less stress on the sides of the outer housing member. For example, in one embodiment, a manufactured polymer for such use could have a CTE less than or equal to about 50 millimeters/meter/° C., and in another embodiment, a manufactured polymer for such use could have a CTE less than or equal to about 35 millimeters/meter/° C. In one implementation, an additive can be added to a polymer so as to bring CTE closer to that of glass. As examples, the additives can be particles or fibers which can be formed from glass or ceramic. Also, as noted above, the thickness of the protective side member can be thin, for example, the thickness can be on the order of about 1 mm or less in one embodiment. 
     In still other embodiments, the protective side materials can be formed from multiple materials that can be alternated, intertwined or layered. The layer of material against the edges of the outer housing member of glass can have a CTE relatively close to that of glass while an outer layer can have a higher CTE that can permit a greater range of material, such as polymers (e.g., plastics). 
     The protective side members are able to be thin yet be cosmetically unintrusive. For example, in some embodiments, the thickness (t1) for the protective side member can be less than 1 mm (e.g., 0.8 mm). Also, in some embodiments, the thickness (t2) of the outer housing member can be less than 5 mm (e.g., 1 mm). However, these thicknesses are exemplary and vary with the size of the electronic device housing and with desired strength. Using a strengthened material for the protective side members as noted above can also be advantageous. Nevertheless, the provisioning of thin protective side members for outer housing members, such as glass covers, facilitates providing portable electronic device housings that are compact and thin yet resistant to side impact damage to the outer housing members. 
     According to another aspect, a glass member for which a component (e.g., peripheral side member) is being formed around can be protected during a molding process. A metal mold is normally used in molding. However, the metal mold can damage (e.g., scratch) a glass member during molding. To mitigate the chance of damage to a glass member, the metal mold (i.e., its inner surfaces) can be coated. The coating can, for example, be a thin layer of polytetrafluoroethylene (PTFE) or polyimide film.
