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 aircraft canopy breaking device, having means for penetrating the canopy lazing material upon application of an applied force from the rising ejection seat to the penetrating means. The device further comprises prepositioning means for prepositioning the penetrating means at a fixed distance from the canopy glazing material, shielding the penetrating means from inadvertently contacting the canopy glazing material, other material or personnel, and compressing whereby upon application of a force the penetrating means contacts the canopy glazing material causing crack propagation in the canopy glazing material.
