    摘要: Infrared imaging at wavelengths longer than the silicon bandgap energy (>1100 nm) typically require expensive focal plane arrays fabricated from compound semiconductors (InSb or HgCdTe) or use of slower silicon microbolometer technology. Furthermore, these technologies are available in relatively small array sizes, whereas silicon focal plane arrays are easily available with 10 megapixels or more array size. A new technique is disclosed to up convert infrared light to wavelengths detectable by silicon focal plane arrays, or other detector technologies, thereby enabling a low-cost, high pixel count infrared imaging system.

    摘要: A pupilometer comprises image capturing means, illumination means comprising two spaced apart light sources, stimulation means, and image processing software, the illumination means generating and emitting light of a first wave-length, and the stimulation means generating and emitting light of a second wavelength. The illumination means is arranged to one or both sides of said image capturing means and, in use, shines light towards the eyeball, the image processing software receiving data from the image capturing means, and by processing said data according to an algorithm establishes the distance between the surface of the eyeball and the camera.

    摘要: Investment performance indices and methods of their formulation are described. The indices are determined by selecting a representative subset of assets (e.g., exchange-traded index funds) from a relatively larger number of possibilities in a given asset class. A performance index for the asset class is created by determining optimized weightings in each asset in the subset. The weightings can be optimized according to any number of optimization algorithms, including MVO, CVaR, and G-CAPM and tailored to a given investor risk profile. One or more “investor-centered” indices may be generated in this manner, for the asset class.

    摘要: A bearing arrangement to reduce the effects of thermal expansion in a marine transmission includes a pinion gear thrust bearing, a clutch shaft thrust bearing, a shaft roller bearing and a thrust washer. The clutch shaft thrust bearing is retained on one end of a clutch shaft and the shaft roller bearing is retained on the other end of the clutch shaft. A pinion gear is rotatably retained on the clutch shaft. The pinion gear thrust bearing is retained on the pinion gear with a bearing retainer. The thrust washer is retained on the bearing retainer. An end of the clutch shaft thrust bearing rotates relative to the thrust washer and makes contact therewith. The length of thermal expansion in the transmission housing is limited to the distance between the opposing ends of the two thrust bearings.

    摘要: A connection system for sealingly interconnecting components of a high pressure fluid flow system, for example, an automobile engine air intake. In one embodiment, the system includes a conduit defining a groove that is locked in a corresponding groove defined by a component, for example, an engine intake. An interlock ring is placed in the conduit groove. A clamp is placed over the interlock ring, however, the clamp and ring can be an integral component. When tightened, the clamp forces the ring into the conduit groove, which presses the conduit into sealing and/or locking engagement with the component groove. A corresponding method of installing the conduit with the connection assembly includes fitting the conduit over the component, fitting the ring in the conduit groove, and clamping the ring into the conduit groove to sealingly couple the conduit to the component.
