A pair of electric goggles is disclosed. The goggles include a conductive lens mounted onto a frame adapted to be electrically connected to an electric socket in order to raise the temperature of the lens, when powered. The goggles are provided with a strap for attaching to a helmet, the strap has a strap clip designed to have the electric socket attached thereto. The electric socket is meant to be electrically connected to a power supply via a power cable. With the combination of a strain relief clip located below the electric socket, the power cable can be positioned in a predetermined configuration, which unencumbers the user from the power cable when detaching or removing the goggles.

A method, equation, system, and device for electrically heating Indium Tin Oxide (ITO) and other transparent conductive materials having a uniform sheet resistivity for defogging and de-icing in a cold environment. The use of nonparallel busbars for connecting the conductive materials reduces excessive and dangerous hot zones. The mathematical analysis and equations provide a means of precisely providing an intermittent electrical connection so that the Watt density and heating is uniform, allowing much higher temperature for de-icing and defogging and more efficient use of energy. This same concept can be used for three dimensional formed heaters to compensate for non uniform sheet resistivity. Also shown are a means of improved busbar designs and an equation and a means of altering sheet resistivity to produce electric heaters with non parallel busbars of various shapes for uniform heating

Power saving method providing a burst of power for defogging an eye-shield apparatus with a thin-film heater, comprising: activating the heater from an off power level to an on-demand mode or from a preliminary intermediate power level during an active-on mode to a max power level and continuing heating for a predetermined first period of time, automatically reducing power after the first period of time and sustaining the lesser power for a second predetermined period of time, after which program control automatically turns off the heater, or automatically reduces the heat back to the preliminary intermediate power level depending upon the initial state of the heater upon activating the burst of power, whether on or off. The method may be repeated as often as necessary from off level in the on-demand mode, or from within a continuous active-on mode.

A helmet has a fan forcing air into a ducting channel to provide air circulation within the helmet for distributing the exhaust air over a faceplate linked to the helmet for eliminating moisture and frost from the faceplate's interior surface. A heating element warms the circulating air for warmth in extremely cold weather. A wiper is installed above the faceplate for clearing moisture from the faceplate's surface. The faceplate is coated with a photochromic material for causing the lightening and darkening of the faceplate dependent upon the ambient light. A pair of lights are mounted on the front and rear of the helmet for safety. A pair of audio headphones, a microphone, and a transceiver are mounted within the helmet for communication with a cellular telephone. A battery provides power for powering the fan heating elements, the wiper, and the lights.

A visor assembly of a helmet having a helmet shell is provided. The visor assembly includes a visor pivotally connectable to the helmet shell via left and right visor mounting sections. The visor has an inner surface facing a cavity of the helmet shell and an outer surface, and is provided with a heating system. The visor assembly further has a connection assembly including an electrical connector located on the outer surface of the visor proximate a front portion thereof. The electrical connector is operatively connected to the heating system and is adapted to be connected to a power cable for providing electrical power to the heating system. The visor assembly also includes a cable retaining element located on the outer surface of the visor proximate one of the visor mounting sections. The cable retaining element has a clip adapted to removably attach the power cable on the visor.

An active anti-fog eyewear system includes a lens with a conductive layer and a power source to provide an electrical current to the conductive layer. When the current is provided to the conductive layer, the conductive layer generates heat. A portion of the conductive layer that is positioned in front of the eyes of a wearer of the eyewear, and a corresponding portion of the lens, is heated more rapidly than other portions of the conductive layer and lens. Condensed water vapor is rapidly cleared from the portion of lens that is positioned in front of the wearer’s eyes. The lens can include electrodes positioned near the top of the lens to direct the current to the portion of the conductive layer that is positioned within a line of sight of the wearer.

Proposed is a transparent heating element for an eye protector such as goggles for snowmobiling, skiing, motorcycling, and the like on which a lens is mounted, and is a manufacturing method thereof. On a surface of a transparent base that configures the lens of the eye protector, a lattice film formed of a dried material or a calcined material of a conductive ink or a conductive paste is provided. The lattice film has a line width of 2.5 μm to 20 μm, a lattice pitch of 0.1 mm to 5.0 mm, a surface resistance value of 10 Ω/cm.sup.2 to 50 Ω/cm.sup.2, and a light transmittance of 90% when the transparent base is excluded. An anti-fog coating treatment is performed on the opposite surface of the transparent base. The surface resistance value is partially changed by changing the lattice pitch.
