## Background
RELATED APPLICATIONS
This patent application claims priority from U.S. Provisional Patent Application Ser. No. 61/395898 filed on May, 18, 2010 titled “APPARATUSES AND METHODS FOR COMBINING MIRRORS WITH ELECTRONICS” and is hereby incorporated by reference into the present application.


BACKGROUND OF THE INVENTION
1. Field of Invention
The invention relates generally to mirrors, and more specifically to combining mirrors with electronics in medicine cabinets.
2. Art Background
Mirrors are used in various rooms of a dwelling such as in any room of a home, or in a hotel room, such as a bath room, living room, bed room, etc. Often, when a mirror is used indoors, light is needed to adequately illuminate the person using the mirror. Light requires energy, and when lights are left on after a person uses a mirror energy is wasted. This can present a problem.
When backlight is used to illuminate a person who is looking into a mirror, it is desirable to provide soft and uniform light since the person will be looking in the direction of the light in order to use the mirror. A light that is too bright could strain and/or damage the person's eyes. Such a light can waste energy by providing more light than is necessary to illuminate the person using the mirror. This can present a problem.
Modern life can present time pressure for people. Often requiring a person to multitask. Examples of multitasking are trying to receive information while spending time in a bathroom while preparing for the day. Electronic presentation of information is not available in the bathroom. This can present a problem.

FIG. 1 illustrates various combinations of electronic devices with glass layers, generally at 100, according to embodiments of the invention. With reference to FIG. 1, a back side of a glass layer 102a is shown. The glass layer 102a is used in a medicine cabinet door and can be referred to interchangeably as a glass layer or an outer glass layer. One form of electronic device, a transducer 104 is attached to the glass layer 102a. The transducer 104 is any one of a number of transducers that will impart a vibrational excitation to the glass layer 102a. For example, a piezoelectric transducer, a moving coil transducer, etc. In one non-limiting example, a transducer such as an NXT-HK-PSS-0088-4 ohm acoustic exciter from Hi Wave Technology is used. Signals are fed to the transducer 104 via wires (not shown) to provide an input that results in a vibration imparted to the glass layer 102a by the transducer 104. The glass layer 102a moves in response to the vibration imparted by the transducer 104 which causes sound waves to be generated in the vicinity of the glass layer 102a. A person in the vicinity of the glass layer 102a can hear the sounds generated thereby. Alternatively, a transducer such as an acoustic speaker can be used to transmit sound. One or more apertures can be located in the medicine cabinet door to facilitate coupling of sound energy from the interior of the medicine cabinet to the exterior.
A back side of another glass layer 102b is shown and is illustrated with another form of electronic device attached thereto, an information display 106. The information display 106 can be in various embodiments an information display used to display video signals to a person viewing the information display from a font side of the glass layer 102b. The information display 106 can be referred to by various terms, by those knowledgeable in the art as; a media display panel, a flat panel, a liquid crystal display (LCD), a plasma display, a display, a TV, etc. No limitation is implied by the use of the term used to refer to the information display. In some instances, an information display contains all of the components to provide a standalone television, e.g., TV tuner, power supply, inverter, etc. In other instances, the information display is just the panel on which video information is displayed, minus power supply, etc. In some embodiments the information display provides an image appearing to have a three-dimensional quality (3D).
Signals are sent to the information display from a variety of sources such as from a television tuner, a video play back device, streaming video over the Internet, a smart phone, a tablet computer, a laptop computer, etc. Medicine cabinets incorporating information displays according to the teachings of embodiments contained herein are used in a variety of places. A non-limiting list of such places includes but is not limited to hotels, public bathrooms, and private bath rooms.
A control 110 is illustrated on the glass layer 102b. The control 110 is used to operate various electronic devices that are incorporated into the medicine cabinet door. The control 110 is typically connected to an electronic device such as 104, 106, 108a and 108b via wires (not shown) and can be operated by a user wirelessly from a front side of the glass layer. The control 110 can be, for example, a wireless control used to control the flat panel. In one embodiment, the control 110 is an IR control utilizing wireless communication in the infrared spectrum. In some embodiments, the control 110 is a capacitive touch control, which responds to a user's touch. Such a control is described in a United States Patent Application filed concurrently having client matter number 101404.P004, which is hereby incorporated by reference. In another embodiment, a smart phone is used to download an application that runs on the user's smart phone and uses the phones wireless functionality to control the media display device including streaming video and audio to the information display.
A backside of another glass layer 102c is illustrated with backlight assemblies 108a, and 108b. Backlight assemblies 108a, and 108b are described more fully below in conjunction with FIG. 6 through FIG. 9. Backlight assemblies, in general, provide a source of scattered light to a front side of a glass layer so that a user can see her or himself in the front side of the glass layer that is prepared as a mirror for viewing reflections thereon.
In various embodiments, the control 110 is provided on any of the glass layers 102a, 102b, and 102c for use with various electronic devices.
FIG. 2 illustrates a combination of electronic devices and a glass layer, generally at 200, according to embodiments of the invention. With reference to FIG. 2, the transducer 104 is shown attached to a back side of a glass layer 202. Additional optional transducers 204 are illustrated. One or more transducers are utilized to provide an acceptable level of sound volume to a user sanding in the vicinity of a front side of the glass layer 202. An information display 106 is attached to the back side of the glass layer 202. The backlight assemblies 108a and 108b are attached to the backside of the glass layer 202. An optional mirror defogger 212 is attached to the backside of the glass layer 202 as shown in FIG. 2. Alternatively, the mirror defogger 212 can be held in place with a frame.

FIG. 6A illustrates a device for providing backlight, generally at 600, according to embodiments of the invention. With reference to FIG. 6A, a glass layer 602a has a front side 602b and a back side generally indicated at 602c. The backside 602c of the glass layer 602a is prepared into several areas. A first area, indicated at 604 scatters light and a second area, indicated at 606a and 606b reflects light. 604, 606a, and 606b extend into the plane of FIG. 6A to form an area having units of length squared, e.g., square inches, square centimeter, etc. Light incident upon the front side of the glass layer 602b will be reflected from the second area 606a and 606b, thereby providing a mirror to a user who views the glass layer from the front side 602b. A reflective coating has been applied to the second area 606a and 606b to make it reflective. One non-limiting example of a reflective coating is a coating made from silver paint.
The first area 604 scatters light and extends into the plane of the figure as described above. In one non-limiting example, the first area is rectangular as shown in 652 or 654 in FIG. 6B. The first area 652 or 654 can be formed into any desired shape. With reference back to FIG. 6A, the back side surface of the glass 602a coincident with the first area 604 can be prepared in a variety of ways to produce the desired scattering of light incident thereon. For example, the first area 604 can be sandblasted, acid etched, etc. to produce the desired scattering. A diffuser 608 is shaped to cover the first area. The diffuser 608 will have an area similar to the first area but usually slightly larger to provide a uniform illumination of light when viewed from the front side; therefore if the first area is rectangular the diffuser will be rectangular. This is done to conserve material and to permit a light source to be positioned close to the edge of the first area 604. In one embodiment, acrylic sheet is used for the diffuser material. In one or more embodiments ACRYLITE® EndLighten acrylic sheet from EVONIK Industries is used for the diffuser material. A layer of paint applied over the first area 604 can also be used for the diffuser material.
A light source 610 is positioned on the backside 602c of the glass layer and next to the diffuser 608. The light source emits light which enters the diffuser 608 and leaves through the scattering area 604 as indicated at 612. The light 612 illuminates a user who views her or himself from the front side 602b. 
In various embodiments, the light source 610 is a distributed light source emitting light along the length of the diffuser 608. In one or more embodiments, the light source 610 is made from an array of light emitting diodes (LEDs). Alternatively, a distributed light source is made from a fluorescent light tube that extends along the diffuser 608. In yet other embodiments, the distributed light source is made from an array of incandescent light bulbs. The devices for providing backlight described herein provide light sufficient for a user of the medicine cabinet to see his or her reflection in the reflective portion of the glass layer (mirror) while standing in front of the medicine cabinet. The intensity of the light sources can be sized to provide enough illumination for the user to see his or her reflection without supplemental lighting.
FIG. 6B illustrates a front view of a glass layer with backlight, generally at 650, according to embodiments of the invention. With reference to FIG. 6B, a scattering area 652 and 654 are provided on the glass layer 602b. The shape of the scattering areas is rectangular; however the scattering areas can be configured into any shape.
In some embodiments, when a wireless control system is used to control electronic devices contained in the door of the medicine cabinet, it can be advantageous to remove or reduce the mirror coating as shown at 656. An infrared receiver can be located on the backside of the glass layer in the region defined by 656. Control of the electronic devices contained with the medicine cabinet door is accomplished with a handheld transmitter as is known to those of skill in the art. Alternatively, other wireless communication technology can be employed such as wireless technology that operates at radio frequency (RF), including Bluetooth communication links.
FIG. 7 illustrates a distributed light source, generally at 700, according to embodiments of the invention. With reference to FIG. 7, the diffuser 608 (shown in FIG. 7 in rectangular form) is illustrated in perspective view. A distributed light source 720 contains a number of discreet light elements 722a through 722n. Discreet light elements 722a through 722n emit light that enters the diffuser 608, on a surface 710, scatters within a volume of diffuser 608 or on a surface of diffuser 608, such as a surface 702a, a surface 702b, a surface 702c, and a surface 702d and is then directed out of the diffuser 608 as indicated at 724a through 724n through a surface 712 of the diffuser 608. In some embodiments, the surfaces 702a, 702b, 702c, and 702d are colored white to enhance internal reflection of light within the diffuser 608 such that light emitted from the surface 712 is maximized. Coloring the surfaces to enhance the reflection of light, such as white, silver, or another color can be accomplished in various ways such by painting, application of tape, etc.
The surface 710 can be polished to minimize reflection of light therefrom. In various embodiments, the distributed light source 720 is an array of light emitting diodes (LEDs). One non-limiting example of a distributed light source is an 8 to 10 inch length of LEDs which draws about 8.8 watts of electrical power and operates at 24 volts. In one non-limiting example, three of these LED arrays are used to provide a continuous distributed source of light that is approximately 30 inches long. Any length of light source can be created and employed in embodiments of the invention.
FIG. 8 illustrates mounting a light source at an angle, generally at 800, according to embodiments of the invention. With reference to FIG. 8, in one embodiment, an edge of a diffuser 808 is cut to an angle of approximately 50 degrees, indicated at 830. The width of the LED array 810 is often wider than the interior space that is available in a medicine cabinet door. Therefore the diffuser material is cut at an angle to facilitate packaging the LED array 810 within the low volume of the medicine cabinet door while still coupling a large amount of light from the LEDs 822 into the diffuser 808. This is done to provide a thin medicine cabinet door. Light emitted from the LEDs 822 is coupled into the diffuser 808 and passes through a glass layer 802a and out the front side of the glass layer 802b as indicated at 840. As described above, the glass layer is prepared with a first area 804 that scatters light and a second area 806 that reflects light.
In one embodiment, the diffuser 808 is made from a sheet of plastic such as acrylic sheet by cutting the angle of the edge to approximately 50 degrees. Other angles can be selected; consideration is given to the space constraints of the medicine cabinet door and the width of the area that is illuminated with the backlight assembly.
FIG. 9 illustrates another light diffuser, generally at 900, according to embodiments of the invention. With reference to FIG. 9, a glass layer 902a has a front side 902b and a backside indicated at 903. The glass layer 902a has a first area 902e that scatters light and a second area indicated at 902c and 902d that reflects light. A distributed light source 910 is attached to the back side 903 of the glass layer 902a. Light is emitted from a light element 922. Light element 922 can be an array of light elements extending into the plane of the figure as described above in conjunction with the preceding figures. A light reflector 930 replaces the light diffuser 608 or 808 (shown in the preceding figures) and extends into the plane of the figure as described above. The light reflector 930 is located on the back side 903 and over the first area 902e. The light reflector 930 has a reflective surface 932 that reflects light 912 out the first area 902e as indicated at 912. The light reflector 930 can be made from any material that reflects light such as metal, etc. Light 912 is visible to a user observing the front side 902b of the glass layer 902a. 
Alternatively, light elements 922 can be arranged over the first area 902e to provide direct backlighting. The first area 902e scatters light. Scattering of light 912 passing through the first area 902e can be enhanced by the application of additional scattering material. A non-limiting list of additional scattering materials is a plastic film, a layer of paint, a sheet of plastic, a layer of glass, a layer of etched glass, a layer of sandblasted glass, a layer of translucent material, a custom user defined scattering layer.
