Abstract: A method for optimizing bandwidth selection of a radar transmission in a frequency bandwidth in which the frequency bandwidth is divided into a plurality of sub-bands having a plurality of different bandwidths. The energy level is measured for each sub-band and a range resolution is also determined for each sub-band. Thereafter, a sub-band is selected in the frequency range where the signal to interference plus noise ratio plus the range resolution is maximum. Thereafter, a radar transmission is transmitted in the selected sub-band with a bandwidth corresponding to the bandwidth of the selected sub-band.

Abstract: A phase-resolved heterodyne shearing interferometer has been developed for high-rate, whole field observations of transient surface motion. The sensor utilizes polarization multiplexing and multiple carrier frequencies to separate each segment of a shearing Mach-Zehnder interferometer. Post-processing routines have been developed to recombine the segments by extracting the scattered object phase from Doppler shifted intermediate carrier frequencies, providing quantitative relative phase changes and information to create variable shear, phase resolved shearographic fringe patterns without temporal or spatial phase shifting.

Abstract: A polymer-micelle complex suitable for use as an aid to preparing fibers, particularly nanofibers, by electrospinning. The polymer-micelle complex may be designed to impart viscosity, surface tension and conductivity properties optimal for electrospinning. By incorporating the complex as a secondary ingredient, one may electrospin sparingly soluble or low molecular weight polymers. Moreover, the polymer-micelle complex can be used as a generic carrier for preparing fibers incorporating other desired materials, such as rigid or globular (hard-to-spin) polymers, enzymes, cells, viral particles and nanoparticles.

Abstract: The munition employs an energetically initiated electromagnetic pulse through a coil which induces a voltage intended to be used for the operation of an electronic time delay circuit and subsequent ignition of a detonation device. Explosive energy from a primer is employed to move a generator core through a generator coil to induce the voltage. The voltage is supplied to a delay circuit. After a set time, the delay circuit supplies power to a laser igniter which detonates the munition. A striker assembly, in addition to initiating the primer, functions as an out of line safety as well as an electric safety.

Abstract: A multivariate digital separation of classes and display device and method for generating pictures of data set comprised of points in hyperspace. An input device may include a keyboard, a laboratory instrument such as a mass spectrometer, a reader of computer readable medium, or a network interface device. An output device may include a monitor used in conjunction with either a 2D or 3D printer or both. A computer processor receives data from the input device and performs a series of steps to create a 2D or 3D image of the pairs-hyperspace of all pairs of classes in data set. The resulting image is then produced in a non-transitory medium by at least one of the output devices. The processor steps include the use of maximizing the degree of separation between all classes in the data set as well as transformation of separated data points of all classes into pairs-hyperspace.

Abstract: Various embodiments are described that relate to an antenna mount. Multiple antennas can be mounted on the antenna mount. These antennas can work together or be independent of one another. In an example of working together, one antenna can be a transmission antenna while the second antenna can be a reception antenna. The transmission antenna and reception antenna can function with regard to the same communication signal.

The system also comprises a reflector configured to reflect a designated signal to the collection antenna and configured to reflect a non-designated signal away from the collection antenna.

Abstract: Various embodiments are described that relate to co-polarization between a first antenna and a second antenna. The first antenna and second antenna can be configured such that co-polarization between the two is increased (e.g., maximized) while cross-polarization is decreased (e.g., minimized). This can be accomplished by physical orientation of the first antenna against the second antenna and/or through powering the first antenna and second antenna differently with phase delay.

Abstract: Various embodiments associated with use of an echo signal are described. A plurality of sensors can be deployed to obtain editions of a signal of interest. The signal of interest may be so far away from the sensors that the editions collected are too noisy to be analyzed. A processing center can send an echo signal to the sensors and the sensors can respond to the processing center with a signal edition of the signal of interest and the echo signal. Since the processing center knows information about the echo signal, offsets among the sensors can be calculated based on the returned echo signals. These offsets can then be used to align the signal editions. At the processing center, the aligned signal editions can be combined into a combined signal and a demodulation scheme for the combined signal can be determined and then used for demodulation of the signal.

Abstract: Various embodiments are described that relate to a detector. The detector can include a loop functioning at a high frequency that emits a magnetic field. The magnetic field can be retrieved and a comparison can be made between the emitted magnetic field and the retrieved magnetic field. If there is substantially little difference between the emitted and retrieved field, then a determination can be that no object is present. Conversely, if there is a substantial difference between the emitted and retrieved field, then the determination can be that an object is present and thus the object is detected. If the object is present, the returned magnetic field can be further analyzed to determine the type of object that is detected.

Abstract: The present invention provides a high concentration bleach generator apparatus and a system and method for its use. The apparatus includes a housing containing brine, anionic and cationic chambers. Electrodes in the anionic and cationic chambers separate salt from brine into hydrogen gas, chlorine gas and an alkali and alkaline hydroxide mass. The hydrogen gas vents through a hydrogen selective membrane. A pump conveys the chlorine gas to the cationic chamber, where it combines with the alkali and alkaline hydroxide mass to form a bleach solution. Users can draw off the bleach and use it to disinfect water. The system also provides a system housing, a larger brine reservoir and a data processor allowing a user to select a desired bleach concentration for production.

Abstract: Various embodiments are described that relate to radio beamforming waveform transmission. Transmission can occur, for example, in three manners. The first manner is time-based where waveform transmission is staggered at the same frequency. The second manner is frequency-based where different frequencies are used at one time. This third manner is a combination of time and frequency such that simultaneous transmission occurs, but at different times different frequencies are used.

Abstract: A nanoparticle sensor apparatus includes a silicon-based nanoparticle having a centrosymmetric crystalline structure. A lanthanide atom embedded within the silicon-based nanoparticle provides light emission when the sensor apparatus undergoes pressure loading. This sensor apparatus may be encapsulated in a polymer matrix to form a nanoparticle sensor matrix apparatus which may be located on or in a structure. To measure the pressure on such a structure, a UV light source illuminates the sensor apparatus. An optical emission detector detects the intensity of light emitted from the sensor in response, while a processor correlates that intensity to the pressure loading.
