6881939, Apr 19, 2005

Filed:

May 3, 2002

Appl. No.:

10/140049

Inventors:

Thomas J. Hamilton - Holland MI, US
Barry D. Scott - Orleans MI, US

Assignee:

Jackson Products, Inc. - St. Charles MO

International Classification:

H01J040/14
G01J001/32

US Classification:

250205, 250214 R, 2502011, 349 14

Abstract:

An auto darkening eye protection device comprising a shutter assembly adjustable between a clear state and a dark state and a control circuit. The control circuit is provided with a microcontroller, a delivery circuit, a sensing circuit and a weld detect circuit. The microcontroller is switchable between a sleep mode and a wake-up mode. The delivery circuit outputs a dark state drive signal to the shutter assembly to switch the shutter assembly from the clear state to the dark state upon enablement of the delivery circuit. The sensing circuit senses the occurrence of a welding arc and provides an output indicative of the occurrence of the welding arc. The weld detect circuit receives the output of the sensing circuit. The weld detect circuit enables a dark state drive signal to be delivered to the shutter assembly by the delivery circuit, and a signal to be delivered to the microcontroller to switch the microcontroller from the sleep mode to the wake-up mode whereby the shutter assembly is switched to the dark state without the aid of the microcontroller.

US Classification:

250214R, 2502011, 349 14

Abstract:

An auto darkening eye protection device comprising a shutter assembly and a control circuit in electrical communication with the shutter assembly. The shutter assembly is adjustable between a clear state and a dark state. The control circuit comprises a microcontroller programmed to store a plurality of memory presets including at least one setting corresponding to the operation of the shutter assembly. At least two of the plurality of memory presets are individually configured for a specific type of welding. In another embodiment, an auto darkening eye protection device is provided, the device comprising a shutter assembly and a control circuit in electrical communication with the shutter assembly. The shutter assembly is adjustable between a clear state and a dark state. The control circuit comprises a microcontroller programmed to monitor and store at least one parameter corresponding to the operation of the auto darkening eye protection device.
