    Abstract: A counter measure system is provided having a unitary infrared transparent dome including a look angle greater than 180. The dome has two hemispherical regions, with a second region having a truncated bottom end defining an opening to a central cavity inside which electro-optical elements are disposed. The electro-optical elements can view outward through the dome at the look angle. The second region on the dome has a complementary curvature as the first region by continuing a similar radius beyond a transverse horizontal axis or equator. The dome is mounted to a base, which also may be referred to as a bezel. The base defines a rabbet extending circumferentially about the base imaginary center defining an aperture. The base and the dome are formed from different materials but have equivalent coefficients of thermal expansion. In one embodiment the dome if formed from sapphire and the base is titanium.

    Abstract: A proximity fuse includes an electric-field (E-field) sensor to detect electrical disturbances from an object that is external and distinct from a device carrying the proximity fuse. The E-field sensor detects or senses E-fields versus time in order to provide omnidirectional coverage of the device carrying the proximity fuse. When the device carrying the fuse is a missile having warhead, the proximity fuse is connected with detonation logic that detonates the warhead at a desired time to destroy or neutralize the object, which is typically a threat, such as another missile.

    Abstract: A system and method is provided for analog to digital conversion, the system having: a front end whereby a current is converted to digital pulses; and a back end with a coarse conversion unit outputting a pulse count; and a fine conversion unit outputting a count time measurement count; wherein said back end unit is configured to combine said pulse count and said count time measurement to produce a high dynamic range output, said output being the product of the one more than the pulse count and the integration time divided by the sum of the integration time and the count time management count.

    Abstract: The system and method of improving the analysis of and implementation of a combat identification (CID) server system including providing correlation reports. There are at least two forms of correlation report, namely incident report and a summation report. The summation report has two types of totals, a summary total of all interrogations, and a breakdown of totals based on the Source JU. In one example, a correlated incident would be the combination of a Lock On or Mark Point with a Weapon Release, Disengage, or Attack.
