Abstract: One or more excitation energy sources emit light in an excitation spectrum and direct the emitted light as an excitation beam to the emitting surface of a wavelength conversion element directly or via reflection. Distinct areas of the emitting surface are coated with one or more distinct fluorescent phosphors. The phosphor-coated areas receive the excitation beam and generate a sequence of fluoresced light beams at a light output, each fluoresced beam of a narrow spectrum determined by the type of phosphor and the excitation spectrum. The fluoresced beams travel parallel to an emitting axis at a non-zero angle to axes associated with the excitation beams.

Abstract: A multi-DMD projection system uses an extended X-cube color splitting/recombining prism to implement splitting and recombining functions at different sections of the cube. Light directed from a white light source is split into red, green and blue components in a lower section of the cube. The components are directed to respective first, second and third DMDs for separate modulations and reentered into the X-cube prism by TIR prism for recombining at an upper section of the cube.

The start up systems and methods include supplying a hydrogen containing fluid to both the cathode electrode and the anode electrode of the fuel cell at substantially the same time during a first stage in the start up, ceasing the supply of the hydrogen containing fluid to the cathode electrode during a second stage of the start up, and supplying an oxidant to the cathode electrode at a third stage in the start up of the fuel cell.

Abstract: A multi-mode color filter 400 having an inner hub region 402 used to mount the color filter 400 to a motor shaft. A first track 404 and a second track 406 of color filter segments are formed on the color filter, as is an optional clear track 406. The first and second tracks each have a different set of color filters. One set of filters is chosen to improve image brightness, another set is selected to improve color saturation. Typically, the set of filters used to improve brightness includes one or more clear segments, while the set of filters selected to improve color saturation does not. Depending on the image being projected, the user or the display controller moves the color wheel to select a particular filter set.

Abstract: A system and method for the modulation of light propagating along an optical path, for example the optical path in a projection display system. As light in the optical path travels from a light source to a display screen, it is shaped and modulated by the various components of the optical path so that the intended visual image appears on the display screen. In accordance with the present invention, a mirror disposed proximate the optical path is operable to be selectively inserted and removed from the optical path to alternately direct the light from one portion of the optical path to another, or to a light dump where it can be absorbed such that the associated heat energy may be properly dissipated. In a preferred embodiment, the mirror is a fold mirror mounted at a stop of the system to fold the light beam approximately 90 degrees when the mirror is inserted in the optical path.

Abstract: Performance in solid polymer electrolyte fuel cells can be improved by varying the characteristics of the ionomer used in the electrode of a membrane electrode assembly. For instance, increasing the ionomer to catalyst ratio can allow for improved performance under drier operating conditions (e.g., when less humidified reactants or higher operating temperatures are used) or when starting up in below freezing conditions.
