Description:
TECHNICAL FIELD OF THE INVENTION 
     The present invention is directed, in general, to wireless devices and, more specifically, to a cellular telephone with a built-in personal mirror. 
     BACKGROUND OF THE INVENTION 
     Reliable predictions indicate that there will be over 300 million cellular telephone customers worldwide by the year 2000. Within the United States, cellular service is offered by cellular service providers, by the regional Bell companies, and by the national long distance operators. The enhanced competition has driven the price of cellular service down to the point where it is affordable to a large segment of the population. 
     The current generation of cellular phones are used primarily for voice conversations between a subscriber and another party through the wireless network. These cell phone handsets are smaller and lighter in weight than their predecessors and provide more features. In fact, the newest generations of handsets are often small enough to fit inside a shirt pocket while also providing several display lines of alphanumeric characters. 
     As handsets approach a nominal convenient small size, manufacturers continue to search for cost-effective features that may distinguish their particular handset configurations from handsets produced by other vendors. For instance, handsets were initially black in color, but handsets of one or more colors and patterns are now readily available. Cell phones also come with numerous accessories that provide a user with ergonomic advantages or personal convenience enhancements to the user, such as leather carrying cases, ear plugs or headphones, recharging units, and the like. 
     There is a need in the art for additional cost-effective ergonomic and/or personal enhancements that a cell phone manufacturer may add to cellular phones in order to distinguish the manufacturer&#39;s products. 
     SUMMARY OF THE INVENTION 
     To address the above-discussed deficiencies of the prior art, it is a primary object of the present invention to provide a cellular telephone (or other cordless telephone handset) that contains an integrated personal (or vanity) mirror. According to one embodiment of the present invention, there is provided a cellular telephone comprising: 1) a handset case; 2) a display associated with the handset case capable of displaying alphanumeric characters when the cellular telephone is operated; and 3) a personal mirror associated with the cellular telephone. 
     According to one embodiment of the present invention, the cellular telephone further comprises a handset cover associated with the handset case. 
     According to another embodiment of the present invention, the handset cover is rotatably coupled to a portion of the handset case. 
     According to still another embodiment of the present invention, the personal mirror is disposed on a surface of the handset cover. 
     According to yet another embodiment of the present invention, the personal mirror is removably mounted on a surface of the handset cover. 
     According to a further embodiment of the present invention, a portion of the handset cover forms a compartment and the personal mirror covers the compartment when the personal mirror is removably mounted on the handset cover. 
     According to a still further embodiment of the present invention, the cellular telephone further comprises a light source associated with the handset cover. 
     According to a yet further embodiment of the present invention, the light source is activated when the handset cover is rotated away from the handset case.

     DETAILED DESCRIPTION 
     FIG.  1  and FIG. 2, discussed below, and the various embodiments used to describe the principles of the present invention in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the invention. Those skilled in the art will understand that the principles of the present invention may be implemented in any suitably arranged cellular telephone. 
     FIG. 1 illustrates an, exemplary embodiment of a communication handset with an integrated personal mirror. Handset  101  comprises transmit/receive antenna  105 , alphanumeric display  110 , keyboard  115 , handset case  120 , speaker  122 , handset cover  125 , microphone  127 , optional mirror illuminator (light)  130 , and exemplary personal mirror  135 . Handset case  120  provides an enclosure for a majority of the circuitry associated with handset  101 . The operations of antenna  105 , display  110 , keyboard  115 , handset case  120 , speaker  122 , and microphone  127  are well known in the art and need not be discussed in greater detail. 
     Handset cover  125  provides a cover for all or a portion of the user control and display associated with handset case  120 . Optionally, handset cover  125  may also serve as the enclosure and protection for a portion of the circuitry associated with handset  101 . Typically, handset cover  125  may cover keyboard  115  as protection against inadvertent entry of key strokes, while leaving display  110  available for constant viewing. 
     In one embodiment, handset cover  125  may comprise at least one mirror illuminator  130  for illumination of personal mirror  135  and the user&#39;s face. In an advantageous embodiment of the present invention, illuminator  130  is a low power light bulb that automatically illuminates when handset cover  125  is rotated away from handset case  120 . Personal mirror  135 , located on a surface of handset cover  135 , serves as a vanity mirror, providing a reflection of the user. Personal mirror  135  may be manufactured from a variety of reflective materials. In one preferred embodiment, personal mirror  135  may be manufactured from a durable, light weight reflective film such as reflective Mylar. Personal mirror  135  provides the ability for the handset holder to conveniently view his or her image without the need for a separate mirror. 
     FIG. 2 illustrates an exemplary embodiment of a portion of handset  101 , which includes a sliding mirror and a convenience compartment. In this embodiment, handset  101  comprises handset cover  225 , microphone  227 , optional mirror illuminator  230 , sliding personal mirror  235 , and convenience compartment  245 . Sliding personal mirror  235  covers convenience compartment  245 , with convenience compartment  245  being exposed when personal mirror  235  is moved from the cover position. In one embodiment, convenience compartment  245  may have space for notes, coins, paper currency, cosmetics, or other small objects. 
     In another embodiment, handset cover  225  and personal mirror  235  may be configured so that the mirror is hinged on one edge to mechanically attach to the handset cover  225 . When personal mirror  235  is placed in the up or open position, convenience compartment  245  may be accessed, as previously described. 
     It will be understood by those familiar with the art, that other configurations of handset  101  with personal mirror  135  (or  235 ) are possible. For instance, although the foregoing disclosure describes the placement of a personal mirror  135  (or  235 ) on a handset cover containing a microphone, it is understood that the handset cover may not include a microphone. Further more, in one embodiment, personal mirror  135 , may be incorporated in a handset case  120 , rather than handset cover  125 . 
     For example, in one embodiment of the present invention, personal mirror  135  may be made of a material of variable reflectivity that covers display  110 . When power is OFF, personal mirror  135  fully reflects light to show the user&#39;s image. However, when power is ON, the reflectivity of personal mirror  135  is greatly reduced so that personal mirror  135  becomes mostly (or completely) transparent. Characters and symbols on display  110  will then be visible through mirror  135 . 
     In another embodiment, personal mirror  135  may be made of a reflective material that may cover a portion of the reverse side of handset case  120 , providing a reflection of the user&#39;s image. 
     In still another embodiment, personal mirror  135  may be include decorative or other features which are otherwise available in mirrors. In one embodiment, one or more edges of personal mirror  135  may be beveled. In another embodiment, personal mirror  135  may be completely or partially configured to provide a reflective image with magnification. 
     Although the present invention has been described in detail, those skilled in the art should understand that they can make various changes, substitutions and alterations herein without departing from the spirit and scope of the invention in its broadest form.
