Abstract: An auto darkening eye protection device comprising a shutter assembly and a control circuit. The shutter assembly is adjustable between a light state and a dark state. The control circuit comprises a sensing circuit, a weld detect circuit, a positive voltage generator, and a negative voltage generator. The sensing circuit senses incident light and provides an output indicative of the incident light. The weld detect circuit receives the output of the sensing circuit, and enables a dark state drive signal to be delivered to the shutter assembly. The positive and negative voltage generators output the dark state drive signal to the shutter assembly to switch the shutter assembly from the light state to the dark state upon enablement by the weld detect circuit. The dark state drive signal includes a high voltage pulse followed by a stable AC waveform. The high voltage pulse is formed by a positive voltage signal and a negative voltage signal.

Abstract: An auto darkening eye protection device including a shutter assembly, a light sensing circuit, a control circuit and a power source. The shutter assembly is adjustable to a plurality of shade levels. The phototransistor of the light sensing circuit senses light from a welding arc and provides an output of the light sensing circuit indicative of the shade level at which the shutter assembly should be operated. The phototransistor is configured for surface mount and has an external base connection connected to the base of the phototransistor. The control circuit is configured to receive the output from the light sensing circuit and provide a drive signal to the shutter assembly responsive to said output, drives the shutter assembly to one of said plurality of shade levels. The present invention provides reduced power consumption, improved attenuation of low intensity light signals, a sharp rise time from the phototransistor in response to high intensity light, and allows implementation into a smaller sleeker eye protection device.

Abstract: The Visor Hinged Lens System (VHLS) is an optical accessory that is made of conventional materials, such as plastic, metal, wood, glass, and the like, consisting of an apparatus that is affixed to the visor or brim of a hat or some other headgear, that enables the user to shield his or her eyes; and with a simple adjustment, involving a hinged mechanism, the apparatus can be pushed forward, allowing the user to have unobstructed vision. The VHLS is a unique combination of eyewear that is connected to an article of headwear, in a temporary or a permanent fashion, allowing the user to flip the eye-protecting portion of the apparatus out of the field of vision using a hinged axis, while allowing the same apparatus to be returned to its original position with an opposing motion.

Abstract: An eye shield assembly useful in training students in non-deadly force, firearms and martial arts has an opaque first eye shield which is coupled to an apertured second eye shield by connecting together adjustable straps on both eye shields. One eye shield covers the eyes while the other eye shield forms a portion of the head strap. The opaque first eye shield simulates substantial or complete blindness while the apertured second eye shield simulates tunnel vision, both conditions being possible during an encounter with an adversary. By utilizing the eye shield assembly, the trainee becomes acclimated to sight impairment and learns to employ the skills obtained by his or her training in situations where there is sight impairment.

Abstract: A welding helmet having high structual integrity is formed of a single sheet of composite material, such as Kevlar fabric impregnated with a phenolic thermoset resin; a viewing port in the front of the helmet includes a welding lens is either of fixed or automatically darkening type; and curves, bends, folds and steps in the composite material and trim pieces in the viewing port area and about the peripheral rim of the helmet shell provide additional stiffening for the helmet. A method of making a welding helmet of a single sheet of composite material includes pre-forming the composite material to a shape similar to that of the finished molding helmet shape, and placing the pre-shaped composite material in a compression mold and closing the mold to mold the composite material to shape while curing the composite material by applying heat other otherwise assisting in the curing of the composite material; and mounting a welding lens in a viewing port of the welding helmet.

Abstract: A welding system with an automatically operated helmet closes the helmet's hood, and thus its face mask, before turning on a welding electrode. The system includes an actuator with a piston that mount to the helmet's headband and hood, respectively. Only when the system detects that the mask is closed will power to the electrode be actuated. This system is controlled by a safety circuit, which the welder simply plugs the helmet into for automatic control. If the welder does not plug into the safety circuit, the system operates similar to a conventional welding system.
