A phosphor screen for image forming including phosphor material being excitable by light in a wavelength λ1. The phosphor screen receives an optical image from an image forming optical system and produces the optical image at a second wavelength λ2. The phosphor screen includes a phosphor layer comprising the phosphor material. A short-pass reflective coating is positioned on a first side of the phosphor layer. The short-pass reflective coating transmits the wavelength λ1 and reflects the wavelength λ2. A long-pass reflective coating is positioned on a second side of the phosphor layer. The long-pass reflective coating transmits the wavelength λ2 and reflects the wavelength λ1. A first substrate is positioned over the short-pass reflective coating. The first substrate is formed of optically clear and thermal conductive material. A second substrate is positioned over the long-pass reflective coating. The second substrate is formed of long-pass absorptive optical filter material that transmits the wavelength λ2 and absorbs wavelength λ1 from ambient light to prevent the phosphor layer from being excited by the ambient light. The phosphor screen may alternatively be used for a direct-view visual display apparatus. These principles can also be utilized for backlighting and general illumination applications.

A scalable video coding method and apparatus for coding a video sequence, wherein the coefficients in the enhancement layer is classified as belonging to a significant pass when the corresponding coefficient in the base layer is zero, and classified as belonging to a refinement pass when the corresponding coefficient in the base layer is non-zero. For coefficients classified as belonging to the significance pass, an indication is coded to indicate whether the coefficient is zero or non-zero, and if the coefficient is non-zero, coding an indication of the sign of the coefficient. A last_significant_coeff_flag is used to indicate the coding of remaining coefficients in the scanning order can be skipped. For coefficients classified as belonging to the refinement pass, a value to refine the magnitude of the corresponding coefficient in the base layer is coded, and if the coefficient is non-zero, a sign bit may be coded.

Various techniques are disclosed for improving airtight two-phase heat-transfer systems employing a fluid to transfer heat from a heat source to a heat sink while circulating around a fluid circuit, the maximum temperature of the heat sink not exceeding the maximum temperature of the heat source. The properties of those improved systems include (a) maintaining, while the systems are inactive, their internal pressure at a pressure above the saturated-vapor pressure of their heat-transfer fluid; and (b) cooling their internal evaporator surfaces with liquid jets. FIG. 43 illustrates the particular case where a heat-transfer system of the invention is used to cool a piston engine (500) by rejecting, with a condenser (508), heat to the ambient air; and where the system includes a heat-transfer fluid pump (10) and means (401-407) for achieving the former property.

Power roller-side concave grooves are opposed to disk-side concave grooves 19, 19 so as to have angles therebetween in a rolling contact area between a peripheral surface of the power roller and a one-side surface 17 of a disk 16 in an axial direction regardless of a transmission gear ratio of a toroidal continuously variable transmission. Accordingly, the disk-side concave grooves 19, 19 are formed so as to have angles with respect to a circumferential direction of the disk 16 when viewed from a normal direction relative to the one-side surface 17 in the axial direction. Meanwhile, the power roller-side concave grooves are formed into a concentric shape (or a spiral shape) about a central shaft of the power roller. As a result, it is possible to prevent a decrease of a contact area in the rolling contact area regardless of the transmission gear ratio.

A method and laser system effect rapid removal of material from a workpiece by applying heating energy in the form of a light beam to a target location on the workpiece to elevate its temperature while maintaining its dimensional stability. When the target portion of the workpiece is heated, a laser beam is directed for incidence on the heated target location. The laser beam preferably has a processing laser output that is appropriate to effect removal of the target material from the workpiece. The combined incidence of the processing laser output and the heating energy on the target location enables the processing laser output to remove a portion of the target material at a material removal rate that is higher than the material removal rate achievable when the target material is not heated.

A thermal sensor for low level radiation with built-in photo-thermal gain utilizing a thin film of pyro-optical material to modulate the reflectivity and/or transmission of a photonic carrier beam. The photonic carrier beam is modulated by the temperature of the pyro-optical film and detected by typically a silicon detector. A slight temperature increase of the pyro-optical film due to absorption of low level radiation increases the coefficient of absorption of the photonic carrier beam which in turn causes a further increase in temperature of the pyro-optical film. The photonic carrier beam provides power to increase the temperature of the pyro-optical film beyond the heating caused by the absorption of low level radiation alone. This thermal amplification effect provides a radiation sensor with photo-thermal gain.
