Abstract: A self-lit display panel includes a photonic integrated circuit payer including an array of waveguides and an array of out-couplers for out-coupling portions of the illuminating light through pixels of the panel. The self-lit display panel may include a transparent electronic circuitry layer backlit by the photonic integrated circuit layer; the two layers may be on a same substrate or on opposed substrates defining a cell filled with an electro-active material. The configuration allows for chief ray engineering, zonal illuminating, and separate illumination with red, green, and blue illuminating light.

Abstract: A filtration system for use in a respirator includes a base member including a chamber aperture, a rotating member including a filter that rotates with respect to the base member; and a cover with an inhale entry. The inhale entry and the chamber aperture create a path through which air enters the inhale entry, passes through the filter, and exits through the inhale chamber aperture.

Abstract: A respirator includes a first chamber, a second chamber, and a separator that separates the first chamber and the second chamber. A filtration system includes an inhale valve that only allows air to enter the respirator and an exhale valve that only allows air to exit the respirator. The system can be reversed so that the inhale valve and exhale valve may be positioned on either the first or second chamber. A replaceable filter can be provided that includes a supply canister including a supply of filter material, a take-up canister that receives used filter material, and a path between the supply canister and the take-up canister that guides the filter material across the respirator's inhale valve, exhale valve, or both the inhale and exhale valves.

Abstract: A system and method for generating graphical user interfaces is described. In one embodiment a list, forming a first group of images, is received and the list includes a name for each corresponding image. In addition, image data is retrieved for each of the images in the list, the image data for each of the images defining a visual aspect of the graphical-user interface. A behavior attribute for each of the images is then established based, at least in part, upon relative positions of the names in the list, the behavior attributes defining behavior of the images within the graphical-user interface. And the graphical-user interface is generated using the sets of image data and the behavior attributes.

Abstract: The invention provides a method of guiding a portable power-saw across a workpiece being sawn. Apparatus for use in this method comprises a guide member which has a substantially flat surface which may be placed on the flat surface of the workpiece. The guide member has a straight edge and located on the flat surface of the guide member is a rod-holder which is orientated at a right angle or any other desired angle to the straight edge. A rod of material such as wood or plastic is inserted in the rod holder so that the rod extends therefrom for a few inches. The power-saw is then run along the straight edge of the guide member, with the sole plate of the saw maintained in snug contact therewith, until the rod is severed. Then the distance from the severed end of the rod to the straight edge is exactly the same as the distance between the sole plate edge and the saw blade.
