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: What is provided is a receiver-on-a-chip comprising a monolithic integrated circuit that reduces the receiver to a cigarette-pack-sized assembly mountable directly at an antenna element, with a much-increased operational bandwidth and instantaneous bandwidth, increased dynamic range and with a two-order-of-magnitude decrease in size and weight. Moreover, because of the elimination of all of the I/O drivers and attendant circuitry, power consumption is reduced by two-thirds, whereas the mean time before failure is increased to 10,000 hours due to the robustness of the monolithic integrated circuit and use of fiber optics.

Abstract: A bipolar pulse generator is implemented in a simple structure while providing a high efficiency design having a relatively low total size, while still allowing access by fibers used to control a photoconductive switch that activates the generator. The bipolar pulse generator includes a stacked Blumlein generator structure with an additional transmission line connected to a load at its near end and short-circuited at its distal end. An extra transmission line is positioned between the Blumlein generator's structure and the load provides specified limited gap between positive and negative sub-pulses. The bipolar pulse generator further includes a bended Blumlein generator structure, in which an existing intrinsic “stray” transmission line is used to provide the bipolar pulse. Still further, bipolar pulse generator includes stepped transmission lines, with additional switches positioned between steps, which are charged by different voltages.

Abstract: Multiple input and/or gain stage Gilbert cell mixer designs are disclosed. The designs allow one input to be turned on at a time, and are suitable, for example, for use in receiver and transmitter applications. In addition, the designs allow for the inputs of the multi-input Gilbert cell mixer to be connected together, thereby allowing for switching of gain states within the Gilbert cell mixer. The mixer design may include, for example, a Gilbert cell mixer stage, and a plurality of input/gain stages. Each input/gain stage has its output connected to the input of the mixer stage, and is configured for receiving an input signal and applying a gain factor to that input signal to provide a signal for mixing with the LO. Each input/gain stage is configured with stage select circuitry for enabling or disabling that stage, so that only one input/gain stage is active at a time.

Abstract: Techniques are disclosed for analyzing a wireless communications device. The techniques include, for instance, assessing vulnerability of the device, including its susceptibility to jamming, by applying one or more interfering signals to the device and observing the device's response. The techniques further include identifying one or more vulnerabilities that can be exploited in defeating malicious behavior involving use of the device (e.g., such as using the device for remote detonation of explosives). Applying one or more interfering signals to the device may include, for instance, applying a trigger signal and a jamming signal to the device, and adjusting the jamming signal until the trigger signal is rendered ineffective in acting as a trigger signal. Identifying one or more vulnerabilities that can be exploited in defeating malicious behavior may include, for instance, reporting parameters of the one or more interfering signals that result in defeating the malicious behavior.

Abstract: A non-uniformity correction (NUC) process for imaging engines is augmented with real-time pixel substitution capability. This feature checks for pixels that have significantly degraded from their factory performance. Degraded pixels found are then substituted in real time. This process eliminates distractions to the camera system operator and prevents these degraded pixels from degrading the subjective image quality.

Abstract: The invention provides an actuator apparatus and method where a source provides electrons to a target material wherein electrical work is performed. A beta emission process comprises a source material emitting electrons which are then captured by a target material. The actuator's source vanes rotate within an electric field between the target chutes' walls, generating torque. The principal providing torque and power is the change in energy as a vane gets closer to the outer walls. During the release and capture process, electrical work is performed which, in turn, is transferred into mechanical work in the form of rotation of the rotor. Specific applications include a radioisotope fueled rotary actuator for micro and nano air vehicles employed as the main form of propulsion.

Abstract: A sensor is used to detect and track a plurality of objects by using a separate track window for each object. Such sensors may be electro optical or infrared. Each object of interest (potential target) in the sensor FOV has a unique track window assigned. This allows independent control of video frame summing for each object to maintain a constant (optimized) signal to noise ratio (SNR) over an extremely large signal dynamic range and reduces track jitter by the simultaneous tracking of multiple objects.

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: A transmission line array is used for explosive/contraband detection using nuclear quadrupole resonance in which the array is driven in-phase with synchrony frequency-swept signals. Each of the balanced transmission lines is fed with a low power swept frequency source and stimulated emissions are picked out with a directional coupler. Location is provided using a cross grid array or a phase detector is used for each balanced line, with phase determining the distance to the sensed substance.

Abstract: Rather than using balanced transmission lines the stimulated response due to nuclear quadrupole resonance can be detected using a single monopole, with multiple monopoles improving substance detection.

Abstract: Nuclear quadrupole resonance substance detection at a distance is provided by crossed or overlapping high frequency beams in which the frequency of one of the beams is offset with respect to the frequency of the other beam by an amount equal to the resonant frequency of the non-linear material to be detected. The presence of energy at the offset frequency within the overlapping beams pumps any non-linear material within the overlapping beams to cause stimulated emission which is detected, in one embodiment, utilizing a network analyzer, along with correlation of the detected stimulated emission signature with a library of signatures for predetermined substances.

Abstract: Outside air enters a ram air scoop on an aircraft frame, and is ducted to a ram air control valve. The air control valve outputs a desired air mass flow to a cyclone air-water separator which removes moisture and produces a dry air flow. A heater assembly heats the dry air to a desired temperature and directs the heated air into an equipment bay enclosure on the aircraft. The relative humidity of the heated air is sensed by an air moisture sensor which produces a corresponding signal. Other sensors disposed near a payload in the bay enclosure produce corresponding air temperature and air pressure signals. All the sensor signals are input to a processor or controller configured to activate the air control valve and the heater assembly according to set points for temperature and humidity that are specified for the payload in the bay enclosure.

Abstract: A compact multi-cycle high power microwave generator and a method of using the generator to generate microwave signals is disclosed and claimed. The apparatus includes one or more charged transmission line sections. Each transmission line section includes a first conductor that is section-specific and a second conductor that is common to all of the sections. A switch is associated with each section, each switch being operatively connected to a respective one of the first conductors. The apparatus includes third, common conductor that is not charged and that is operatively connected to each of the first conductors through its respective switch. The apparatus further includes a load, with the second conductor, the third conductor, and the load being operatively connected. Thus, the number of section-specific conductors, the number of charged transmission line sections, and the number of switches are all equal. Engagement of the switches generates a multi-cycle microwave pulse.
