Abstract: A method for fabrication of a field effect transistor gate, with or without field plates, includes the steps of defining a relatively thin Schottky metal layer by a lithography/metal liftoff or metal deposition/etch process on a semiconductor surface. This is followed by depositing a dielectric passivation layer over the entire wafer and defining a second lithographic pattern coincident with or slightly inset from the boundaries of the previously defined metal gate layer. This is followed by etching the dielectric using dry or wet etching techniques and stripping the resist, followed by exposing and developing a third resist pattern to define the thicker gate metal layers required for electrical conductivity and also for the field plate if one is utilized. The final step is depositing gate and/or field plate metal, resulting in a gate electrode and an integral field plate.

Abstract: A microradio is provided with a hysteretic switch to permit an optimum range increasing charging cycle, with the charging cycle being long relative to the transmit cycle. Secondly, an ensemble of microradios permits an n2 power enhancement to increase range with coherent operation. Various multi-frequency techniques are used both for parasitic powering and to isolate powering and transmit cycles. Applications for microradios and specifically for ensembles of microradios include authentication, tracking, fluid flow sensing, identification, terrain surveillance including crop health sensing and detection of improvised explosive devices, biohazard and containment breach detection, and biomedical applications including the use of microradios attached to molecular tags to destroy tagged cells when the microradios are activated. Microradio deployment includes the use of paints or other coatings containing microradios, greases and aerosols.

Abstract: A method of providing a defense against a shaped charge uses an outer and an inner armor layer provided with a medial space between these outer and inner armor layers. One or more defensive shaped charges are positioned in the medial space. If the outer armor layer is attacked by ordnance having an offensive shaped charge, one or more of the defensive shaped charges positioned in the medial space is detonated so as to degrade the effectiveness of the offensive shaped charge and prevent penetration of the inner armor layer.

Abstract: An air-based vertical launch system is described by means of which ballistic missile defense can be achieved effectively from a large aircraft. A method for ensuring safe missile egress is proposed. A method for ensuring that the missile strikes the ballistic missile payload section is also proposed. Together, the air basing method employing vertical (or near-vertical) launch and semi-active laser guidance yield an affordable and operationally effective missile defense against both tactical and long-range ballistic missiles. The affordability of missile defense is enhanced by the ability of an aircraft equipped with a vertical launcher to simultaneously carry out several defensive and offensive missions and to provide other capabilities such as satellite launch at other times.

Abstract: Statistics are collected for each network user, including signal bandwidth (BW), required receive power (RRP) for decoding a user signal, and available transmit margin (ATM). Users are ordered by BW from greatest to smallest. Users with a greatest BW are then ordered by ATM from lowest to highest, and divided into lower half users having lower ATMs, and upper half users having higher ATMs. A two-tier channel plan is defined, and lower half users are assigned to channels in a lower tier. An upper half user is assigned a channel in an upper tier after placing a lower half user in the same channel in the lower tier, if the upper half user's ATM is >(U User RRP+L User RRP). Otherwise, the user is assigned a different channel in the lower tier. The dividing and subsequent steps repeat for any remaining sets of users requiring successively smaller signal bandwidths.

Abstract: A method for fusion of image block adjustments for the generation of a ground control network constituting a Metric Information Network (MIN). Utilizing the subject. fusion algorithm it is possible to duplicate the results of an extremely large simultaneous image block adjustment by sequentially performing smaller image block adjustments on small overlapping areas of interest and taking the results to update a metric information network. Note, intermediate results for less than all the imagery provide usable updates to the metric information network. The result of the infusion of sequential image block adjustments into the metric information network is that one can obtain the accuracy provided by an extremely large single image block adjustment, and do so in manageable chunks or segments involving conventional computer resources.

The sub-pixel resolution permits utilization of smaller cost-effective focal plane arrays by giving the small focal plane array a resolution associated with much larger focal plane arrays.

Abstract: An automatic system is provided for alerting ground personnel as to the existence of a threat to commercial aircraft in which the threat is determined by a classified system, but in which the local area network employed by the military missile warning is isolated from an unclassified local network coupled to the aircraft's transponder which transmits the threat existence and status to ground personnel. The barrier to transmitting classified information involves both filtering between the classified LAN and unclassified LAN, the use of only discrete signaling lines in the classified LAN isolated by opto-electronics to provide physical separation between the two local area networks, and communications formatting which precludes the transmission of classified information across the barrier between the classified local area network and the unclassified local area network.
