Abstract: A system and method for providing a munitions launching system with dynamic shock isolation in which a spring plate skirt having an integral spring arrangement is provided between a munitions frame and a munitions extension, the spring plate skirt defining an opening that provides for the uninterrupted flow of expelled rocket gases, as well as underside access to the munitions frame.

Abstract: A voltage to current converter comprising a composite amplifier arrangement having a common-base transistor for providing voltage to current conversion, the input current to common-base transistor is corrected to account for the temperature drift of the transistor and variations in the bias supply voltage.

Abstract: A reversible sealing mechanism for sealing a bulkhead having a first central aperture defined along a central axis and disposed between first and second compartments includes a cover member having a recess defined therein by a substantially cylindrical sidewall and adapted to cover the first central aperture. A wedge ring having a generally cylindrical body is accommodated by the first and second central apertures and is configured to operatively engage the cover member. A mechanical input is operative to reversibly rotate the wedge ring about the central axis such that a rotation of the wedge ring in a first direction urges the cover member in the axial direction into a sealed position.

Abstract: The invention provides for electromagnetic transmission and reception used in detecting relative changes associated with nano devices existing within an oil reservoir. The system enables monitoring of the relative movement of the nano devices in the oil and/or water over a given area based on the incremental or relative changes of the intensity of the reflections over time. In one embodiment, a source of electromagnetic energy from an array of antennae transmitting immediately in the far field recharges a power source embedded in the nano devices. In another embodiment, the return signals from the nano devices maps the morphology of ensembles of nano devices. In yet another embodiment the transmission controls the movement of the nano devices and controls the function preformed by the nano devices relative to effecting changes in the well to improve production of oil.

Abstract: An adjustable hinge block includes first and second complementary members, each defining therein a first and a second slit respectively. The members are adapted to mate with each other such that the first and second slits at least partially align with each other to define a third slit. First and second wing members protrude from the members respectively such that the wing members lie on opposite sides of the third slit when the members mate with each other. The wing members each define therein a first and a second aperture respectively, which first and second apertures are adapted to receive a fastener. First and second side members, each define therein a third and a fourth aperture respectively, such that the third and fourth apertures is adapted to align with the first and second apertures respectively.

Abstract: In a radar system that detects relatively fast moving targets using a radar clutter map comprising a plurality of range-azimuth cells containing parameter data values indicative of time averaged echo returns for affecting alarm threshold levels at range-azimuth locations scanned by the radar system antenna, a method for detecting relatively slow moving targets in a substantially homogeneous surveillance region, the method comprising the steps of obtaining from the radar clutter map a value corresponding to parameter data of a given cell under test (CUT); determining a second parameter data value using parameter data values of other cells from the plurality of range-azimuth cells from the radar clutter map; comparing the parameter data value of the CUT with the second parameter data value; and generating a signal indicative of a target detection when the CUT parameter data value exceeds the second parameter data value by a given threshold corresponding to a target false alarm rate.
