TL;DR: In this paper, a bar code reader has an integrated scanning component module which is mounted on a printed circuit board, enabling the module to be used with a generic PCB, and an abusedetector or accelerometer is provided for determining when the device is exposed to deceleration above a predetermined limit, and optionally for automatically shutting down applications programs and for providing a black box record of a short time frame before the device was exposed to an unexpected shock.
Patent
Removable cover for protecting a reticle, system including and method of using the same
TL;DR: In this article, a removable cover for protecting a reticle used in a lithography system is described, which includes a frame and a membrane supported by the frame and is transparent to an inspection wavelength such that the reticle can be inspected with the removable cover in place.
Patent
Mask handling method, and mask and device or apparatus comprising a gripper therefor, device manufacturing method and device manufactured thereby
TL;DR: In this paper, a mask for use in a lithographic projection apparatus comprises three brackets arranged on the circumference of the mask, each of which is provided with grooves directed to a common imaginary point and are intended to cooperate with three pins provided on a mask gripper.
Patent

Elastomeric hinge for a swingable agricultural machine element
TL;DR: In this paper, a mower-conditioner has an elongated stationary member and a cover swingable by means of a flexible element made of reinforced elastomeric material, such as a section of tire carcass or rubber belting.
Patent
Electromigration method for making stained glass photomasks
TL;DR: A glass photomasks having a stained pattern within the glass for use in photolithographic processes are made by exposing and developing a photoresist on a sheet of glass and subsequently migrating stain-producing ions, such as silver and/or copper, into the surface of the glass under the influence of an electric field and moderately elevated temperatures as mentioned in this paper.
Patent
Mask alignment method
TL;DR: In this paper, the first and second masks are mounted in first-and second-support members, adjusting the first support member to align the masks with respect to a common alignment pin, removing the second support member, mounting the substrate in a third-support member, aligning the substrate with the first mask and magnetically holding it in place.
Patent
Device for aligning a photomask on a printed circuit board
TL;DR: In this paper, an exposure frame for aligning and holding photomasks in registration with a printed circuit board coated with a light sensitive material is described, which facilitates good registration between the board and mask.
