| 20120070115 | ALL GLASS FIBER LASER CLADDING MODE STRIPPER - A system configured to generate an optical beam from a fiber laser is presented. The system includes a fiber gain medium having a core and a cladding, the core being configured to convert radiation from a pump beam into an output beam, the cladding having a mode propagating section and a mode stripping section bounded on a near end and a distal end by the mode propagating section, the mode stripping section of the cladding being configured to scatter excess pump radiation received from the mode propagating section in a substantially outwardly radial direction. The system also includes a rigid support member into which the fiber gain medium is placed, the rigid support member completely encompassing the mode stripping section of the cladding and joined to the fiber at the mode propagating section of the cladding. | 03-22-2012 |
| 20120057220 | HIGH POWER FIBER LASER SYSTEM - A tapered fiber bundle device couples optical power from an optical power source into an output fiber. The tapered fiber bundle device includes a tapered fiber bundle including a set of bundled fibers having a near end and a distal end. The near end of the tapered fiber bundle is configured to collect the optical power from the optical power source. Each fiber k in the set of bundled fibers has a first cross-sectional area A | 03-08-2012 |
| 20100284249 | ALERTING SYSTEM FOR A FACILITY - A surveillance system is configured to detect a rotary-wing aircraft approaching a fixed facility and provide a warning upon detection. The system includes acoustic processing nodes that receive acoustic signals from the environment surrounding the fixed facility. As the nodes receive the acoustic signals, the nodes perform a spectral analysis of the signals to detect if the source of the acoustic signals is a rotary-wing aircraft. Additionally, based upon the acoustic signals, the nodes detect an altitude of the rotary-wing aircraft and a distance between the rotary-wing aircraft and the fixed facility. In the case where the system identifies the rotary-wing aircraft as encroaching a predefined geographical area outside of the facility, based upon the altitude and distance between the rotary-wing aircraft and the facility, the system generates a warning to allow security forces to intercept the rotary-wing aircraft prior to its arrival at the facility. | 11-11-2010 |
| 20100124660 | TECHNIQUES FOR FORMING TEMPORARY PROTECTIVE COATINGS AND BONDABLE SURFACES - A method for forming temporary protective coatings and bondable surfaces is disclosed. In the method, a soluble layer is disposed on a material surface, such as the interior surfaces of cell walls of a web material. The soluble material is then removed or leached from the web material to form and expose a roughly textured, bondable surface for bonding with another material, such as AVCOAT insulation. Use of the soluble layer, therefore, enhances the bondability of any surface that requires good adhesion, such as where the surface is difficult to reach for conventional surface preparation techniques. | 05-20-2010 |
| 20100024230 | IDENTIFYING A DIRECTIONAL REFERENCE USING RATE GYROS ORIENTED ALONG DIFFERENT AXES - A deployable stationary device includes a device support, rate gyros supported by the device support, the rate gyros being oriented along different axes, and a controller supported by the device support. The controller is arranged to receive rate gyro signals from the rate gyros. Each rate gyro signal indicates a rate of rotation about a respective axis associated with a particular rate gyro. The controller is further arranged to perform a vector sum operation based on the rate gyro signals, and generate a direction signal which identifies a direction resulting from performance of the vector summing operation. Such a deployable stationary device is capable of operating as one of a network of such devices in a surveillance system to enable detection and precise location of suspicious activity. | 02-04-2010 |
| 20090269082 | HETERODYNE RECEIVER USING DIFFERENTIAL TEMPERATURE CONTROL OF LASER SOURCES - A heterodyne receiver includes first and second laser sources such as laser diodes which generate optical receiver oscillator (RO) signals having respective RO frequencies. Temperature control circuitry controls a temperature difference between the operating temperatures of the sources such that the RO frequencies differ by a difference frequency corresponding to the temperature difference, the difference frequency being offset from a frequency of a modulated millimeter-wave signal by a predetermined intermediate frequency. An electro-optical nonlinear mixer such as a photodiode receives the optical RO signals and the modulated millimeter-wave signal and generates an electrical intermediate-frequency (IF) signal, which is provided to an electrical amplifier/detector to detect the output signal corresponding to the modulation of the modulated millimeter-wave signal. The receiver may be used as part of a heterodyne transceiver which includes a transmitter, and the transmitter may also employ an optical heterodyne structure for generating a millimeter-wave signal for transmission. There may be sharing of some components between transmitter and receiver by dividing operation into separate transmit and receive intervals. | 10-29-2009 |
| 20090233457 | CONTINUOUS SLIDING ELECTRICAL CONTACT TAPE - The electrical tape has a flexible conductor strip defining a conductor strip contact surface configured to interact with a first electrical connector and a second electrical connector, the flexible conductor strip being arranged to provide electrical connectivity between the first electrical connector and the second electrical connector. The electrical tape has a flexible insulator portion substantially surrounding the flexible conductor strip, the flexible insulator portion being arranged to expose the conductor strip contact surface along the length of the tape. | 09-17-2009 |
| 20090202780 | FORMING A HONEYCOMB STRUCTURE - Formation of a filled honeycomb structure by interleaving layers of material and pre-formed pins made of a desired filler material is disclosed. In one embodiment, the material layers may be pre-impregnated and the pre-formed pins may be made of a foam, insulating material. The fabric layers and the pre-formed elongated foam members are assembled in an interleaved manner to form a raw assembly, and heat is applied to activate the resin and cure the raw assembly. The technique further involves allowing the raw assembly to cool to form a unitary, integral honeycomb structure. | 08-13-2009 |
| 20090035890 | TECHNIQUES FOR DIRECT ENCASEMENT OF CIRCUIT BOARD STRUCTURES - A technique for processing an electronic apparatus (e.g., manufacturing an assembled circuit board, treating an assembled circuit board, etc.) involves applying encasement material to an area of the circuit board assembly while leaving at least a portion of the circuit board assembly exposed. The technique further involves causing the applied encasement material to harden (e.g., heating the encasement material in a curing oven, applying radiation, providing a chemical catalyst, etc.). Application and hardening of the encasement material may take place shortly after circuit board assembly (e.g., by automated equipment at a manufacturing facility in order to treat newly assembled boards) or at some later time in the field (e.g., by a technician servicing a legacy board). | 02-05-2009 |
| 20090034084 | BEAM COMBINATION USING INTERLEAVED OPTICAL PLATES - In a system and method, the emitted beams of multiple diode bar array assemblies are combined to achieve an increase in the resulting power density in the combined output beam, while addressing the need for heat distribution in each of the individual assemblies. The present invention enables the combination of output planes of illumination, to form a single, merged beam of area A | 02-05-2009 |
