Abstract: A reflector comprises a core and a first dielectric mirror formed over at least a portion of the core to reflect light having a preselected wavelength. The reflector may comprise a plurality of dielectric mirrors formed concentrically over the first dielectric mirror to reflect light having the preselected wavelength. The multiple dielectric mirrors may have different diffraction indices. A layer of such reflectors deposited onto the reflective surface of a projection screen may enhance the reflective selectivity of the screen to the preselected wavelength. Reflectors formed to reflect different wavelengths may be deposited onto the reflective surface to enhance selectivity to the different wavelengths and minimize reflection of ambient light.

Abstract: A method, system, apparatus, and computer program product is presented for improving the execution performance of flow-based-program (FBP) programs and improving the execution performance further on systems with additional processing resources (scalability). A FBP supervisor is inserted as the initial executable program, which program will interrogate the features of the operating system upon which it is executing including but not limited to number of processors, memory capacity, auxiliary memory capacity (paging dataset size), and networking capabilities. The supervisor will create an optimum number of processing environments (e.g. threads in a Windows environment) to service the user FBP application. The supervisor will further expose other services to the FBP application which improve the concurrent execution of the work granules (processes) within that FBP application.

Abstract: A protected dual purpose power/enter switch for an integrated receiver/decoder has a first relay and a second relay adapted for operative communication with a motherboard and with each other. A switch and a processor are in operative communication with the first relay. When the device is off, said switch is configured to activate the first and second relay to power up the device, and when said device is on, the first relay connects the switch to the processor as an enter switch. The switch may power off said device by entering a power off menu item displayed by said processor.
