Description:
RELATED APPLICATIONS 
   This application is based on and claims the benefit of priority to Applicant&#39;s co-pending U.S. Provisional Patent Application Ser. No. 60/657,470, entitled “Heated Eyewear” and filed on Mar. 1, 2005, the disclosure of which is expressly incorporated herein in its entirety by reference thereto. 

   FIELD OF THE INVENTION 
   The present invention relates to eyewear and more specifically to heated eyewear. 
   BACKGROUND INFORMATION 
   There are many activities in which a person requires the provision of additional heat. While the heat for most of these activities is supplied by heat sources that introduce heat into the atmosphere in the vicinity of the person, e.g., a building heating system that employs a boiler, radiators, etc., there are some activities for which such a heating source is not available or is insufficient to provide heat in a specific desired location, such as near or adjacent to a person&#39;s face or eyes. 
   Thus, there is a need for an apparatus for directing heat to a specific desired location, such as near or adjacent to a person&#39;s face or eyes. 
   SUMMARY OF THE INVENTION 
   The present invention, according to one example embodiment thereof, relates to eyewear, e.g., any apparatus to be worn on or adjacent to a person&#39;s eyes. The eyewear includes a heating element that is configured to provide heat. Advantageously, the heat provided is sufficient to provide at least some improvement in warmth to the wearer. In addition or alternatively, the heat provided may be sufficient to perform some other function, such as preventing the accumulation on at least a portion of the eyewear or at least a portion of the wearer&#39;s face of, e.g., snow, ice, fog or any other type of matter, whether environmental or otherwise. 
   The eyewear may also include an actuation element for actuating the heating element. The actuation element may operate automatically or manually. Power for the heating element to generate heat may be provided by a power source, such as a battery. A backup power source may also be employed.

   DETAILED DESCRIPTION 
     FIG. 1  is a front view of a set of eyewear, in accordance with one embodiment of the present invention. It should be understood that the term “eyewear” may refer to any type of eyewear, including but not limited to: prescription or non-prescription eyeglasses; prescription or non-prescription sunglasses; goggles, visors, shields, helmets or any other type of apparatus that may be worn by a wearer for any conceivable purpose such as for skiing, skydiving, hunting, paintball or other entertainment or interactive games, safety, combat, infrared or night-vision, driving or riding vehicles, welding or any other type of construction work, any type of laboratory work, police work, space travel, etc. 
     FIG. 1  illustrates a pair of eyeglasses  10 , in accordance with one embodiment of the present invention. While the present invention is described hereinbelow as a pair of eyeglasses, it should be understood that any type of eyewear as defined above may be employed. In the embodiment shown, the eyeglasses  10  include a pair of lenses  12  that are supported by a frame  14 . The lenses  12  may be fabricated from any type of material, including but not limited to plastic, glass, etc., and may be water, solar, scratch, salt water and/or glare resistant and/or fire retardant. In addition, the frame  14  may be fabricated from any type of material, including but not limited to metal, plastic, glass, etc., and may also be water, solar, scratch, salt water and/or glare resistant and/or fire retardant. The lenses  12  and/or the frame  14  may be flexible or rigid, depending on the desired application. The lenses  12  may have automatic or manually-operated shading or tinting capabilities. 
   The frame  14  may include a heating element  16 . The heating element  16  is shown in  FIG. 1  as being disposed throughout the entire frame  14 . However, it should be understood that the heating element  16  may being disposed in a part of, or in any portion of, the frame  14 , and/or may be disposed in a part of, or in any portion of, the other components of the eyeglasses  10 . In addition, it should be understood that, while the wire shown in  FIG. 1  forms a single heating element  16 , in various other embodiments, the frame  14  may include one or more heating elements  16  that may or may not be connected to each other and which operate either together or independently from each other. 
   The heating element  16  may be any material or component that is capable of providing heat. In the embodiment shown, the heating element is a heat conductive wire. The wire may be fabricated from any material that conducts heat. 
   The eyeglasses  10  may also include a pair of nose-pieces  18  that are employed to support the eyeglasses  10  on the nose of a wearer. The nose-pieces  18  may also include a heating element  16 . Alternatively, the nose-pieces  18  may be fabricated from a heat insulating material. In this alternative embodiment, the nose-pieces  18  may operate to prevent the heating elements  16  from directly contacting the skin of the wearer. It should also be recognized that, in some embodiments, any other portion or portions of the eyeglasses  10 , e.g., the ear pieces, may be fabricated from a heat insulating material so as to prevent any hot surfaces from directly contacting the skin of the wearer. Alternatively, depending on the amount of heat that is generated by the heating element  16 , it may be preferable that a hot or warm surface does directly contact the skin of the wearer. Thus, depending on the application, the heat generated by the heating element  16  may be provided to the wearer either directly, e.g., by direct contact with the skin, and/or indirectly, e.g., by radiating heat towards the skin of the wearer without actually touching the skin of the wearer. In one embodiment, the heating element  16  may be heated to a temperature of between 50° to 150° F., preferably 70° F. to 110° F., more preferably 80° F. to 100° F., and most preferably about 90° F. 
   The eyeglasses  10  also include ear-pieces  20 . The ear-pieces  20  may be attached to the frame  14  in any manner, such as by a hinge  22  or the like. The hinge  22  may operate to permit the ear-pieces  20  to be folded against the frame  14  when the eyeglasses are not in use. While  FIG. 1  illustrates the general position of the ear-pieces  20 , additional details of the ear-pieces  20  are illustrated in  FIG. 2 . Referring now to  FIG. 2 , there is shown one ear-piece  20 , according to one embodiment of the present invention. In this embodiment, the ear-piece  20  includes a power source  24 . The power source  24  may be any type of component capable of providing a sufficient amount of power to the other components of the eyeglasses  10  so as to heat the heating element  16  to a desired temperature. Advantageously, the power source  24  is a battery, e.g., a conventional watch battery or the like that provides 1 volt/0.25 amperage. Preferably, the power source  24  is replaceable when necessary, although in other embodiments the power source  24  may be integrally formed with or within the ear-piece  20 . It should be understood that the power source  24  need not be located with or within the ear-piece  20 , but may alternatively be located with or within any other part of the eyeglasses  10 . 
   In the embodiment shown, the power source  24  is electrically connected to a voltage protection element  26 , such as a fuse. The voltage protection element  26  is in turn electrically connected to an output amplifier  28 . The output amplifier  28  is in turn electrically connected to a thermistor  30 . The thermistor  30  may function to regulate the amount of heat generated by the heating element  16 . The thermistor  30  is electrically connected to the heating element  16  in the frame  14  by a connecting wire  32 . According to one embodiment, the connecting wire  32  is permanently connected to the heating element  16  in the frame, while in an alternative embodiment, the hinge  22  is configured to selectively connect the connecting wire  32  to the heating element  16 . For instance, in one such embodiment, the connecting wire  32  may be connected to the heating element  16  when the ear-piece  20  is moved to the open position, e.g., the position at which the eyeglasses  10  are worn, while the connecting wire  32  may be disconnected from the heating element  16  when the ear-piece  20  is moved to the closed position, e.g., the position at which the eyeglasses  10  are stored. 
   The eyeglasses  10  may also include an actuation element  34 . In the embodiment shown, the actuation element  34  may be a switch that is located at or within the hinge  22 . The actuation element  34  may be connected to the other electrical components of the eyeglasses  10  and may operate in the manner describe above whereby the heating element  16  is caused to be heated upon the opening of the eyeglasses  10  into the open position. Various other actuation elements  34  may be employed. For instance, the actuation element  34  may be a level-actuatable switch such that the heating element  16  is caused to be heated when the eyeglasses  10  are positioned in a substantially vertical alignment as would be the case when the eyeglasses  10  are worn by a person that is standing upright. Of course, such a level-actuatable switch may operate to heat the heating element  16  at any conceivable position. 
   Another actuation element  34  may be a manually operated switch, located anywhere on the eyeglasses  10 , that is moveable by a wearer in order to selectively turn on, turn off, and/or adjust the heat generated by, the heating element  16 . Still another actuation element  34  may be an automatic mechanism that turns on, turns off, and/or adjusts the heat generated by, the heating element  16  in response to an environmental factor, e.g., including but not limited to temperature, wind speed, barometric pressure, etc. Referring to one example embodiment in which the temperature is the environmental factor, the actuation element  34  may include a temperature sensor that turns on the heating element  16  when the temperature experienced by the wearer is below a pre-determined level, e.g., below freezing, and that automatically causes the heating element  16  to provide additional heat when the temperature is reduced still further below the pre-determined level. Still another actuation element  34  may be a voice-activation mechanism by which a wearer may turn on, turn off or adjust the heat generated by the heating element  16  by speaking a command or by making a particular sound. Still another actuation element  34  may be a remote control mechanism, e.g., a wireless transmitter and receiver arrangement, by which a wearer may turn on, turn off or adjust the heat generated by, the heating element  16 . 
   It should be recognized that the specific components described hereinabove for generating and conveying heat to the heating element or elements  16  are merely one possible arrangement for performing these functions. It should be understood that the components described herein above may be located in or on any portion of the eyeglasses  10  (and where the eyewear is not eyeglasses, the components may be located in or on any portion of the eyewear apparatus), either integrally, permanently or temporarily. Furthermore, any other components that are capable of generating and conveying heat may be used. For instance, the heating element  16  may be electrically powered by different electrical components than those described hereinabove. Additionally, or alternatively, the types of power that may be employed by the heating element  16  may include, without being limited by, solar power, chemical power, electromechanical power, e.g., such as by shaking, hydrogen power, lunar power, nuclear power, or any combination of types of power. In addition, the eyeglasses  10  may include a back-up power source  25  in the event that the primary power source  24  fails to function. Still further, it should be recognized that any of these power types may be employed as the primary power source  24 , and any of these power types may be employed as the back-up or secondary power source  25 . 
   The heating element  16  may also be used in conjunction with other features, such as, without limitation, ground position sensor  36  (“GPS”) technology, a lighting element  38  of any kind, a compass, a clock, and/or a microprocessor electronic memory unit or data unit  40  for the storage, transfer or display of any type of data, including but not limited to service data, directional data, academic or educational data, DVD or other video display data, etc. In one embodiment, the microprocessor electronic memory unit  40  is configured to adjust the temperature range of the heating element  16 . In one embodiment, these additional features of the eyeglasses  10  are powered by the same power source  24  (and/or the same back-up power source  25 ) as is employed by the heating element  16 . Alternatively, other power sources may be provided for these purposes. 
   Thus, the several aforementioned objects and advantages of the present invention are most effectively attained. Those skilled in the art will appreciate that numerous modifications of the exemplary example embodiments described hereinabove may be made without departing from the spirit and scope of the invention. Although various exemplary example embodiments of the present invention have been described and disclosed in detail herein, it should be understood that this invention is in no sense limited thereby and that its scope is to be determined by that of the appended claims.
