    Abstract: A frame assembly for a light shutter including a frame structure for enclosing an electro-optic shutter assembly, the frame structure having a front surface which can be positioned opposite a cover lens, and a switch for controlling an operation mode of the electro-optic shutter assembly, the switch being mounted on the front surface whereby pressure applied to the cover lens activates the switch. The frame assembly can be inserted and used in a welding helmet or other protective eyewear having a standard sized lens aperture.

    Abstract: A multi-stage control for an auto-darkening lens includes a first detector to detect initiation of welding and a second detector to detect continuation of welding after welding has been initiated. The first detector has relatively low sensitivity and fast response time; and the second detector has relatively high sensitivity that can be altered as may be necessary, relatively slow response time to allow opportunity to determine whether welding is continuing as inputs indicative of welding, and adaptive filtering to filter ambient effects and the like from such inputs to avoid false detection of welding. A method of enhancing operation of an auto-darkening lens control that has a detector and associated circuitry to detect initiation of welding substantially independently of time based filtering and to maintain detecting of welding using time based discrimination, comprising coupling control signals and power to an auto-darkening lens via a substantially unimpeded path from a detector to the auto-darkening lens.

    Abstract: A head-mounted display or other optical device which provides at least a first image to at least one eye of a user can be adjusted for changing the alignment of an image path with respect to a user's eye position. An alignment beam generator is mounted so as to move with the image path device so a user can use characteristics of the alignment beam to achieve a desired alignment of the image path. Preferably, the alignment beam is configured, such as by making it substantially narrow-beam, linear and/or non-dispersive, such that beam is substantially invisible to the user until it is within a preferred alignment range, so as to provide a binary or visible/invisible, indicator of alignment.

    Abstract: A welding helmet and lens therefor includes a shield and a lens including a two identical optical components, each including a polarizer, a further polarizer (analyzer) optically between said optical components and effectively shared as an output device from one optical component and an input device for the other optical component, the transmissive axes of respective polarizers of said optical components being operatively oriented relative to one another to improve extinction of light incident on said lens at prescribed angles. The lens may be used in other optical systems. A method of making a light transmission controlling optical system employing two optical components control device, includes assembling a plurality of identical optical components, each having substantially identical alignment characteristics, positioning at least two of the optical components in optical series such that at least one optical component is facing in a direction opposite the facing direction of the other optical component, whereby the polar alignment of at least one part of both of said optical components is equi-angular and opposite sense relative to a reference direction.
