The eye mask core assembly has first and second heat producing areas separated by a distance corresponding to a separation of human eyes and having first and second ends. The eye mask core assembly produces heat in response to the application of a voltage thereto. The covering surrounds the eye mask core assembly. The band is attached to the first and second ends of said eye mask core assembly. The first and second insulated wires have first ends connected to the eye mask core assembly, and second ends for connection to a power supply. ## Claims ### Claim 1 An eye mask, comprising: an eye mask core assembly having first and second eye-shaped portions separated by a distance corresponding to a separation of human eyes and having first and second ends, said eye mask core assembly producing heat in response to an application of a voltage thereto; a band attached to the first and second ends of said eye mask core assembly having first and second ends; and first and second insulated wires having first ends connected to said eye mask core assembly, and second ends for connection to a power supply, wherein said eye mask core assembly is constructed such that when the eye mask is attached to a user's head using said band, said eye mask core assembly disposes said first and second eye-shaped portions in direct contact with surfaces of, and without substantial pressure on, corresponding first and second eyelids of the user to conform to surfaces of corresponding eyeballs of the user, wherein said eye mask core assembly comprises: a support member attached to said first and second ends of said band; and a heating element attached to said support member and coupled to said first and second insulated wires and formed of a flexible substrate, said heating element comprising said first eye-shaped portion and said second eye-shaped portion which are separated by a center portion and a conductor, wherein said conductor in said center portion is configured to electrically connect said first and second eye-shaped portions but is not designed to produce heat, and has a serpentine pattern in said first and second eye-shaped portions producing heat in response to an application of power from said power supply. ### Claim 2 (depends on 1) The eye mask of claim 1, wherein when the eye mask is attached to the user's head using said band, said eye mask core assembly disposes first sides of said first and second eye-shaped portions in proximity to said human eyes and second sides of said first and second eye-shaped portions are in free space. ### Claim 3 (depends on 1) The eye mask of claim 1, wherein said eye mask core assembly further comprises: first and second standoffs each having a first end attached to said heating element and a second end attached to said support member such that said first end of said first standoff is attached to said heating element to the left of said first eye-shaped portion and said first end of said second standoff is attached to said heating element to the right of said first eye-shaped portion; and third and fourth standoffs each having a first end attached to said heating element and a second end attached to said support member such that said first end of said third standoff is attached to said heating element to the left of said second eye-shaped portion and said fourth standoff is attached to said heating element to the right of said second eye-shaped portion. ### Claim 4 (depends on 3) The eye mask of claim 3, wherein said first, second, third, and fourth standoffs are formed with a soft, flexible material. ### Claim 5 (depends on 4) The eye mask of claim 4, wherein said soft, flexible material comprises foam. ### Claim 6 (depends on 1) The eye mask of claim 1, wherein said heating element comprises a flexible polyimide film having a thickness of about 0.33 mm. ### Claim 7 (depends on 1) The eye mask of claim 1, wherein said conductor is formed with a nickel alloy film. ### Claim 8 (depends on 1) The eye mask of claim 1, wherein said support member is formed of a semi-rigid material. ### Claim 9 (depends on 8) The eye mask of claim 8, wherein said semi-rigid material comprises aluminum having a thickness between about 0.010 millimeters (mm) and 0.016 mm. ### Claim 10 (depends on 1) The eye mask of claim 1, wherein said band is formed of an elastic material. ### Claim 11 (depends on 1) The eye mask of claim 1, further comprising: a covering surrounding said eye mask core assembly. ### Claim 12 (depends on 11) The eye mask of claim 11, wherein said covering comprises a cloth made of cotton. ### Claim 13 (depends on 1) The eye mask of claim 1 further comprising: a connector coupled to said second ends of said first and second insulated wires and substantially compliant with the universal serial bus (USB) standard. ### Claim 14 (depends on 1) The eye mask of claim 1 further comprising: a connector coupled to said second ends of said first and second insulated wires and substantially compliant with the Feb. 5, 2009 version of the ANSI/SAE J563 standard. ### Claim 15 An eye mask system, comprising: a regulated power supply for outputting a first voltage having approximately a predetermined value; and an eye mask core assembly coupled to said regulated power supply, comprising: a heating element coupled to and receiving power from said regulated power supply and formed of a flexible substrate, and having first and second heat producing areas which are separated by a center portion at a distance corresponding to a separation of human eyes and having first and second ends, said first and second heat producing areas producing heat in response to an application of power from said regulated power supply, and a conductor, wherein said conductor in said center portion is configured to electrically connect said first and second eye-shaped portions but is not designed to produce heat, and has a serpentine pattern in said first and second heat producing areas producing heat in response to an application of said first voltage; and an attachment system connected to said heating element for causing said heating element to conformally fit over human eyes, said attachment system constructed such that when the eye mask core assembly is attached to a user's head, said eye mask core assembly disposes said first and second heat producing areas in direct contact with surfaces of, and without substantial pressure on, corresponding first and second eyelids of the user to conform to surfaces of corresponding eyeballs of the user, wherein the eye mask system is characterized as being a feed-forward system without feedback. ### Claim 16 (depends on 15) The eye mask system of claim 15, wherein said predetermined value is from about 5.0 volts to about 6.0 volts. ### Claim 17 (depends on 15) The eye mask system of claim 15, wherein said regulated power supply comprises: a plug for connection to an alternating current (AC) mains outlet; and an AC-DC converter having an output coupled to said heating element. ### Claim 18 (depends on 15) The eye mask system of claim 15, wherein said first and second heat producing areas of said heating element are eye-shaped. ### Claim 19 (depends on 15) The eye mask system of claim 15, said first and second heat producing areas heat eyelids of said human eyes to approximately 40 degrees Celsius. ### Claim 20 (depends on 19) The eye mask system of claim 19, wherein said attachment system comprises: a support member having a first end and a second end; a band attached to the first end and to the second end of said support member; and first and second insulated wires having first ends connected to said heating element, and second ends for connection to said regulated power supply.
