    Abstract: A method for manufacturing multiple layers of waveguides is disclosed. Initially, a first cladding layer is deposited on a substrate, a first inner cladding layer is then deposited on the first cladding layer, and a first waveguide material is deposited on the first inner cladding layer. The first inner cladding layer and the first waveguide material are then selectively etched to form a first waveguide layer. Next, a second inner cladding layer followed by a second cladding layer are deposited on the first waveguide layer. The second inner cladding layer and the second cladding layer are removed by using a chemical- mechanical polishing process selective to the first waveguide material. A third inner cladding layer followed by a second waveguide material are deposited on the first waveguide material. The third inner cladding layer and the second waveguide material are then selectively etched to form a second waveguide layer. Finally, a fourth inner cladding layer followed by a third cladding layer are deposited on the second waveguide layer.

    Abstract: A method for nondestructive analysis is disclosed. The method includes measuring a distance between an acoustic source and each of the points to be analyzed (pixels) on the surface of an object. An optimization is then defined using the distance measurements. Thereafter, the object at each target pixel is acoustically bombarded, and the surface response at each pixel is recorded and measured. Optionally, the surface response measurements may be processed to account for extraneous information. The calculated optimization may then be used to generate the early-time line-up of the recorded measurements, and the processed information may be analyzed using the r generated early-time line-up to image the internal structure object.

    Abstract: A bipolar pulse generator circuit generates bipolar pulses and provides an impedance transformation. The circuit is amenable for implementation in a variety of configurations depending on the size and pulse width requirements for the design. It also maximizes energy transfer and may be implemented in a straight forward, easy manner. The generator may be implemented with one or two switches in a three, five or more transmission line implementation and may include inductive stub, which is inherent element of transmission line transformers. The generator may also be implemented in a multi-layer folded configuration, with or without the addition of a ground potential conductor. The generator may also be implemented in stacked or/and balanced configurations.

    Abstract: A method for identifying hostile missile launch locations is disclosed. In response to a receipt of a message containing information regarding a hostile missile had been launched at an aircraft, a determination is made as to whether or not a tail number contained within the message is a valid tail number for the aircraft. If the tail number contained within the message is a valid tail number for the aircraft, another determination is made as to whether or not the aircraft was at a valid location at the time the message was sent. If the aircraft was at a valid location at the time said message was sent, pertinent information are retrieved from the message in order to identify the exact launch location of the hostile missile.

    Abstract: A multiuser detector system with correlation based pruning including a parameter estimation module adapted to receive complex signals, and to produce estimated signature waveforms for each of K co-channel interfering signals. Pre-processing the estimated signature waveforms using an S-matrix module and producing a more valid set of hypotheses, wherein the S-matrix module uses apriori knowledge of an unnormalized cross correlation matrix, and processing the more valid set of hypotheses for pruning with an M-algorithm in a multiuser detector module. An improvement to the M-algorithm in which the interference structure based on the signal correlation matrix used during the optimization process aids in selecting a better subset of hypotheses to test. This approach has the benefit of reducing computational complexity and improving performance over the existing M-algorithm

    Abstract: A microchip, Q-switched, cavity-dumped laser is end-pumped by VCSEL or a laser diode and comprises an electro-optic Q-switch mechanism actively controlled by photoconductive switches. The fast response time of the system and its small dimension produce short pulses (ten pico-second range), with high energy (uJ range). The microchip structure may be built using planar, wafer-like components such that a high-density array of lasers may be manufactured without tight alignment tolerances, providing efficient power or energy scaling.

    Abstract: Real and simulated (virtual) networks are interfaced with one another for carrying out hardware-in-the-loop (HITL) testing and evaluations. A simulated network is modeled at a workstation by running a network simulation or discrete event modeling tool on the workstation. A virtual gateway node is defined in the simulated network, and the gateway node is linked with a network adapter on the workstation. An external real network operating with Internet protocol (IP) is also linked with the adapter. The adapter and the gateway node are configured to (i) translate simulated data packets sent from nodes of the simulated network and designated for the real network, into IP data packets for routing or processing by the real network, and (ii) translate IP data packets sent from nodes of the real network and designated for the simulated network, into simulated data packets for routing or processing by the simulated network.
