    摘要: A tensioning pin system (10) is provided for use in shutter-louver assemblies (12). The major component of the system (10) is a tensioning pin (50) in two mating parts; a pin member (52) and a ferrule member (54) which fit together and rotate with respect to one another. The pin member (52) is lodged within a louver slat (16) while the ferrule member (54) is firmly embedded into the shutter frame (14). The tensioning pin (50) maintains rotational tension for placement of the louver slat (16) and lateral separation between the louver slat (16) and the frame (14). A preferred interface between the pin member (52) and the ferrule member (54) includes an annular protrusion (80) mating with a catch channel (74) while alternate tension interfaces incorporate varying gradients on one of the members with a bead ring on the other member.

    摘要: Method and system for determining whether one or more multipath signals is present in a received signal frame that includes a reference symbol (RS) sequence RS(t;m1) as part of the frame, and for iteratively evaluating a multipath signal that is present. The RS sequence index (m1) for the frame is identified, and first and second Fourier transforms Φ(f;m1;ref) and Φ(f;rec) for the received frame are provided for a selected time segment IS that includes the RS sequence of the received frame. An inverse Fourier transform σ(t;m1) of the ratio of the transforms is computed and analyzed. If at least one multipath signal is present, σ(t;m1) is nonlinearly filtered, and the filtered function is convolved with RS(t;m1). This convolution represents a received signal extension, due to multipath signal(s) presence. A refinement procedure analyzes a contribution to multipath signals from the preceding frame(s). The procedure is iteratively driven toward an optimal representation of any multipath signal(s) present.

    摘要: One embodiment of the present invention provides a switching device that can vary a spin-polarized current based on an input signal. The switching device comprises a first conducting region, a second conducting region, and a half-metal region interposed between the first conducting region and the second conducting region. The half-metal region comprises a material which, at the intrinsic Fermi level, has substantially zero available electronic states in a minority spin channel. Changing the voltage of the half-metal region with respect to the first conducting region moves its Fermi level with respect to the electron energy bands of the first conducting region, which changes the number of available electronic states in the majority spin channel, and in doing so, changes the majority-spin polarized current passing through the switching device.
