This invention provides a tool for tightening and loosening lenses with respect to camera bodies. The tool includes a body that defines a cavity that is slightly larger in diameter than the sidewalls of the lens adjacent the lens face. Within the cavity is a thin, high-friction, elastomeric material that resides between the edges of the lens when the cavity is pressurably engaged over the lens face. The material frictionally couples the tool body to the lens face and adjacent side walls, thereby allowing a predetermined level of torque to be applied to tighten or loosen the lens. The tool can be adapted for attachment to a handle, such as a torque wrench or can include a handle specifically adapted/contoured for grasping by a user's hand.

Tool for installing and removing threaded camera lenses

This invention provides an electro-mechanical auto-focus function for a smaller-diameter lens type that nests, and is removably mounted, within the mounting space and thread arrangement of a larger-diameter lens base of a vision camera assembly housing. In an illustrative embodiment, the camera assembly includes a threaded base having a first diameter, which illustratively defines a C-mount base. A motor-driven gear-reduction drive assembly is mounted internally, and includes teeth that engage corresponding teeth on the outer diameter of a cylindrical focus gear, which has an internal lead screw. The focus gear is freely rotatable, and removably captured, within the threaded C-mount base in a nested, coaxial relationship. The internal lead screw of the focus gear threadingly engages the external threads of a coaxial lens holder. This converts the drive gear rotation into linear/axial lens holder motion. The lens holder includes anti-rotation stops, which allow its linear/axial movement but restrain any rotational motion.

Auto-focus mechanism for vision system camera

A vent screen for an electronic device is provided. The vent screen may include a framework formed from an integral substrate, and a plurality of voids formed in the framework. Typically, the voids are formed by etching away portions of the substrate, and are separated from each another by a plurality of separators formed in the framework. The separators may have a width of less than 1 mm.

Etched vent screens

A position adjuster for a projection device is provided. The position adjuster may include both a coarse adjustment mechanism and a fine adjustment mechanism for positioning the projection device relative a reference surface.

Position adjuster for a device

A projection device is provided. In one embodiment, the projection device may include an optical system mounted within the projection device and having an optical system axis substantially parallel to the optical system. The projection device further may include a combination control operatively coupled to the optical system and having a control axis that is non-parallel to the optical system axis.
