Abstract: A method and apparatus for controlling a radar beam emitted by a radar sym. The invention produces improved high resolution ground mapping by aligning the antenna isogain or isonull lines with the ground radial lines. The antenna axis is rolled by an angle determined from the geometric principles of the unit vectors along the ground radial lines. A new azimuth pointing angle is then computed and implemented. A new azimuth beamshape, azimuth beamwidth and azimuth beam spoiling factor are also computed and implemented.

Abstract: A device for providing crash protection to people aboard a land, air, sea space vehicle. A crash sensor mounted on the vehicle is used to sense a crash, impact or jarring motion. Data from the crash sensor is then transmitted via wireless communication by a signal transmitter to a signal receiver mounted on a harness worn by a crew member or passenger. When a crash signal is received, inflation mechanisms inflate inflatable bladders mounted on the harness, thereby protecting the person wearing the harness.

Abstract: An apparatus is provided for cooling electronic components mounted on a cuit board. The circuit board is placed in thermal contact with a heat sink enclosure that has an interior cavity and a release opening that provides a path from the interior cavity to the external ambient. A meltable pellet blocks the release opening. A wick is bonded to the inside surface of the interior cavity. The device is sealed with a working fluid that permeates the wick. When the components get hot, the heat is transferred through the heat sink enclosure to the working fluid in the wick, causing the working fluid to vaporize. The vapors remain trapped in the interior cavity until the pellet melts, allowing the vapor to be released and the temperature of the heat sink enclosure to be stabilized or lowered.

Abstract: An optical paper detector for use in conjunction with a printing press for sensing the undesirable condition of more than a single sheet of paper being simultaneously fed to the press. The optical paper detector is comprised of an array of wide angle phototransistors connected in parallel which uniformly sense light transmittance through the paper over a relatively large and continuous area to provide an averaging effect so that the optical paper detector is relatively insensitive to local variations in light transmittance. The optical paper detector is equipped with a flat cover that permits flush mounting and provides a self-cleaning wiping action.

Abstract: The present invention is a clamping arrangement for the pins of a stamp perforating cylinder. A plurality of cavities are arranged in a checkerboard fashion on the surface of the stamp perforating cylinder. The pins are mounted along the side walls of the cavities and extend radially outwardly from the surface of the cylinder. The pins are held firmly in place within each cavity by a clamping member, a screw and an elastomer ring. The elastomer ring is installed at the base of the cavity and is held in place by the clamping member and screw. The screw and the clamping member coact to compress and displace outwardly the elastomer ring thereby firmly grasping the pins mounted along the side walls and securing the pins against movement. The clamping arrangement provides for retention of the pins while at the same time it permits easy removal and replacement of individual pins.
