Attorney, Agent or Firm: Renner, Otto, Boisselle & Sklar, LLP
An indicator system and method for an auto-darkening lens or other device that is intended to be placed relatively close to the face of a wearer includes one or more indicators adjacent the lens and generally provides the indicators in the peripheral field of view of the wearer, allowing the indicators to be discerned without having to focus eye vision on them and while allowing the wearer to direct eye focus on a work piece or the like. |

DETAILED DESCRIPTION I claim: 1.
An indicator system for a head mountable apparatus, comprising a number of indicators, an input to provide selective inputs to the indicators to cause the indicators to provide output indications, said indicators generally being in the peripheral field of view of only one eye of a wearer of such head mountable apparatus in ordinary use, said indicators being located relative to each other, whereby the indications provided thereby may be comprehended based on at least one of relative location to each other and location in such head mountable apparatus.
2.
The system of claim 1, wherein the indicators are so positioned in a head mountable apparatus as to be seen if such head mountable apparatus is off the head.
3.
The system of claim 1, wherein the indicators are light emitting diodes.
4.
The system of claim 1, wherein the indicators are located at one side of a center position of such head mountable apparatus as to be viewable primarily in the peripheral field of view of one eye of a wearer.
5.
The system of claim 1, wherein the indicators comprise indicating devices to provide a light output and light conductors to conduct light from respective indicating devices to a location at the peripheral field of view of a wearer.
6.
The system of claim 1, and further comprising in combination therewith a helmet.
7.
The system of claim 6, wherein the helmet is a welding helmet.
8.
The system of claim 6, wherein the helmet is part of a respirator.
9.
The system of claim 6, wherein the helmet is a space helmet.
10.
The system of claim 1, wherein the indicators provide light of different respecfrve colors.
11.
A head mountable welding lens system including, an indicator system comprising a number of indicators, an input to provide selective inputs to the indicators to cause the indicators to provide output indications, said indicators generally being in the peripheral field of view of a wearer of such head mountable welding lens system in ordinary use.
said indicators being located relative to each other, whereby the indications provided thereby may be comprehended based on at least one of relative location to each other and location in such head mountable welding lens system, and a variable transmission welding lens
