  • Patent number: 10111616
    Abstract: Method, apparatus and computer-accessible medium for monitoring sleep quality of a user are described. For example, using such exemplary Method, apparatus and computer-accessible medium, it is possible to collect body movement signals of the user during sleep, and calculate body movement energy of a preset time-slot, based on the body movement signals collected during the preset time-slot. It is also possible to calculate an estimation threshold of a preset estimation time-span including the preset time-slot, based on body movement energy of preset time-slots which are included in the preset estimated time-span. Further, a determination can be made as to a sleep state of the user based on a comparison between the body movement energy of the preset time-slot and the estimation threshold of the preset estimation time-span. Such exemplary Method, apparatus and computer-accessible medium facilitate a strong adaptive ability and highly reliable sleep monitoring.

  • Patent number: 6778146
    Abstract: In a satellite broadcast reception converter, probes are equipped in a circular hole formed in a first circuit board, and plural fixing holes are formed around the circular hole. Snap pawls are formed at open ends of the waveguides formed of sheet metal. The respective snap pawls are inserted in the fixing holes of the first circuit board so as to project to the back surface side of the first circuit board, and the fixing holes of the short caps are snapped into the snap pawls. A dielectric feeder of synthetic resin supported on each waveguide has a first split body with radiation portion projected from the open end of each waveguide and a second split body having a phase converter fixed in the waveguide. The first and second split bodies are unified by inserting a projection equipped to the second split body into a through hole formed at the center of the first split body.

  • Patent number: 6717553
    Abstract: A primary radiator including a waveguide formed by winding a metallic plate into a cylindrical shape and superimposing both ends thereof at a joining portion. Two first flat portions and two second flat portions, extending in the direction of the central axis of the waveguide, are formed so that a first flat portion and a second flat portion alternate at intervals of substantially 90 degrees, thereby forming a total of four flat portions. A dielectric feeder includes a radiator section, an impedance converting section, and a phase converting section.

  • Patent number: 6714166
    Abstract: Each of a first minute radiation pattern and a second minute radiation pattern is provided on a first circuit board so as to be inclined electrically by about 45° from the respective axial lines of a first probe for vertically polarized waves and a second probe for horizontally polarized waves. The first minute radiation pattern is approximately perpendicular to a phase conversion portion of a first dielectric feeder, and the second minute radiation pattern is approximately parallel with a phase conversion portion of a second dielectric feeder. The phase conversion portion of the first dielectric feeder is longer than that of the second dielectric feeder.

  • Publication number: 20030068980
    Abstract: First and second waveguides which have respective axes thereof arranged parallel to each other are respectively held by dielectric feeders. A projection wall or a thick wall is formed as a correction part on a front surface of a waterproof cover which covers radiation parts of the dielectric feeders. Due to such a constitution, when radio waves transmitted from neighboring first and second satellites are converged by a reflector and are incident on the inside of respective waveguides, it is possible to delay a phase of radio waves which pass the waterproof cover by the correction part (projection wall or thick wall) so that it is possible to adjust such that radiation patterns of radio waves which are incident on the respective waveguides are reflected on a common portion of the reflector whereby the required reflector can be miniaturized.
