Abstract: A compact, lightweight, laser target designator uses a TIR bounce geometry to place an end-pumped gain element functionally in the center of the resonator path, thereby allowing the resonator path to be terminated by a pair of crossed Porro prisms, so that the designator produces a high quality beam that is insensitive to alignment and temperature, and is low in manufacturing cost. Some embodiments fold the Porro legs of the resonator path back toward the gain element for compactness. Embodiments use a single gain element as both an oscillator gain element with TIR and as an output amplifier gain element without TIR. Various embodiments use block optical elements in a planar layout on a standard support medium such as aluminum to facilitate automated manufacturing.

Abstract: An adaptive beam steering control system suitable for multiple element systems is provided for coherently forming a beam and tracking a dynamic scenario of a rapidly fading environment. The adaptive beam steering control system and associated method advantageously provide improved continuous beam steering with a faster response time and higher precision than normally attainable by using the greater slope of the nulling error function to perform the beam steering function. Although reciprocity of nulling and beam steering is normally only true for a single pair of elements, the method of the invention extends the process to larger arrays of elements.

Abstract: What is provided is recording capability for each of the modules utilized by the first responders and other personnel within the area of the incident, with the stored information at each of the first responders' modules being read out through the ad hoc network, where it can be uploaded to storage. The stored information can be displayed at an incident commander work station in real time to give the incident commander a realistic view of the timeline and the severity of the incident, as well as the response. The use of the ad hoc network permits offloading stored information from each of the first responders' modules so as to free up storage within the modules. By providing storage at every node of the ad hoc network, one has access to a timeline of the actions at the incident as well as redundancy, which enhances the memories and observational skills of the first responders.

The height of the wire columns is substantially uniform for the plural groups of wire columns, and a length of at least one of the wire columns is greater than the uniform height.

In another aspect, an electronic device package substrate includes wire columns having at least one non-uniformity in lengths of the columns, and the length of a wire column corresponds to a distance of that wire column from the neutral stress point of the substrate.

Abstract: An inertial delay mechanism for use in an explosive projectile is provided. The delay mechanism consists of an inertial delay fuse that is precise, doesn't require sensitive primary explosives and doesn't utilize electronic circuitry. The inertial delay fuse includes a free sliding charge element that strikes an anvil located opposite to the sliding charge element. A delay gap is provided between the sliding charge element and the anvil. Upon impact, the sliding charge element slides forward and impacts the anvil, thereby inducing a shock wave in an initiator charge that subsequently results in detonation of main charges. The design is mechanically simple and robust enough to withstand severe g-loading forces that occur during firing and penetration of a projectile.

Abstract: A method for integrating a slotted waveguide into a CMOS process is disclosed. A slot can be patterned on a SOI wafer by etching a first pad hard mask deposited over the wafer. The slot is then filled with a nitride plug material by depositing a second pad hard mask over the first pad hard mask. A waveguide in association with one or more electronic and photonic devices can also be patterned on the SOI wafer. The trenches can be filled with an isolation material and then polished. Thereafter, the first and second pad hard masks can be stripped from the wafer. The slot can once again be filled with the nitride plug material and patterned. After forming one or more electronic and photonic devices on the wafer using a standard CMOS process, a via can be opened down to the nitride plug and the nitride plug can then be removed.

Abstract: A method for dealing with high inrush current when voltage is applied to mixed voltage logic integrated circuits is disclosed. A depletion N-Channel Metal Oxide Semiconductor Field Effect Transistor (MOSFET) or junction Field Effect Transistor (JFET) is added to a linear voltage regulator in mixed voltage logic integrated circuits. The Field Effect Transistor (FET) is utilized to allow the core voltage to come up with Input/Output voltage prior to turn-on of linear voltage regulator. Turn-on state of FET allows the core voltage to rise with Input/Output voltage until the FET threshold is reached across the gate. When threshold is reached, the FET turns off to allow linear voltage regulator turn on and take over supply power.

Abstract: A method for carrying out electromagnetic cloaking using metamaterial devices requiring anisotropic dielectric permittivity and magnetic permeability may be emulated by specially designed tapered waveguides. This approach leads to low-loss, broadband performance in the visible frequency range, which is difficult to achieve by other means. We apply this technique to electromagnetic cloaking. A broadband, two-dimensional, electromagnetic cloaking is demonstrated in the visible frequency range on a scale ˜100 times the wavelength. Surprisingly, the classic geometry of Newton rings is suited for an experimental demonstration of this effect.
