    摘要： A method of modifying polarity of light is provided. The light propagates through a first transverse plane and has known polarization states in respective cells of the first transverse plane. A first retardation compensator having respective waveplates matching the cells then changes the polarity of the light so that light propagating through a second transverse plane is circularly polarized across the entire second transverse plane. A second retardation compensator includes a plurality of quarter waveplates that change the polarization of the circularly polarized light, so that light passing through a third transverse plane is linearly polarized. The crystal alignment of the quarter waveplates and their shape and configuration are selected so that the direction of the polarization is normal to a radius from a single point.

    摘要： Techniques that may be utilized in reduction of snoop accesses are described. In one embodiment, a method includes receiving a page snoop command that identifies a page address corresponding to a memory access request by an input/output (I/O) device. One or more cache lines that match the page address may be evicted. Furthermore, memory access by a processor core may be monitored to determine whether the processor core memory access is within the page address.

    摘要： Apparatus and systems, as well as methods and articles, may operate to update video display pixels. A video display bus can communicate data to a video display according to specified clock frequencies and a refresh time period. Power conservation can be enhanced by adjusting the specified clock frequencies and/or refresh time period to provide idle time on the video display bus.

    摘要： For at least one disclosed embodiment, a die may be provided that includes a transmission line (or waveguide) and a signal-generating device to generate a pulse on the transmission line and to receive a pulse from the transmission line. A plurality of transistors may be provided along a length of the transmission line to change an impedance of the transmission line. This may change a speed of the pulse along the transmission line or change an effective length of the transmission line. A control device may also control the plurality of transistors based on a sensed temperature of a thermistor device.
