摘要： The present invention is an apparatus which executes a photogrammetry method for calculating soil density. After a user excavates soil, measures the mass of the excavated soil and takes multiple images of the excavation site in combination with a calibration object, a data processor uses the various values obtained from the collected images to create a point cloud data object. The processor used this point cloud data object to create a visual representation of the hole. The processor rotates and scales the visual representation. The processor also uses the point cloud data object in volumetric calculations to determine the volume of the hole. Together with the soil mass, the volume allows calculation of soil density.

摘要： The current invention is an apparatus for concentrating ions in a water stream and a method for using the apparatus to concentrate ions for detection and/or removal.The apparatus is comprised of an electrically charged barrier, a distal electrode having an electrical charge with a sign opposite to the electrical charge of the barrier, and a proximate electrode having an electrical charge with a sign corresponding to the electrical charge of the barrier. The apparatus further includes a moving water stream which is processed to comprise an ion-depleted stream and an ion-concentrated stream located between the distal electrode and the first surface, a first diversion structure to divert the ion-concentrated stream, a second diversion structure to divert the ion-depleted stream, and an electrical power source operatively coupled with the distal and proximate electrodes.

摘要： 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.

摘要： 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.

摘要： The subject invention provides a grenade which comprises a means of indicating, to a user, that the grenade's striker assembly has been activated, and thus provides an indication that the grenade has been initiated. Specifically, the subject invention provides such indication of striker activation, and thus grenade initiation, which is evident to the user by touch and feel, without the need for purposeful inspection of the grenade by said user. More specifically, the subject invention modifies the grenade's striker assembly to create a means to obstruct the safety lever from returning to its original position.

摘要： A vehicle barrier apparatus includes a horizontal barrier component, a vertical barrier component, at least one rigid stabilizer beam having two end surfaces and at least one elongated side surface. One end of the stabilizer beam is affixed to the vertical barrier component. The elongated side surface of the stabilizer beam is affixed to the horizontal barrier component to prevent rotational movement of the vertical barrier component. A lower surface of the horizontal barrier component is a friction-enhanced surface which creates a sliding friction interface upon contact of a moving vehicle with the vertical barrier component.

摘要： A laboratory system has demonstrated the measurement of three degrees of vibrational freedom simultaneously using a single beam through heterodyne speckle imaging. The random interference pattern generated by the illumination of a rough surface with coherent light can be exploited to extract information about the surface motion. The optical speckle pattern is heterodyne mixed with a coherent reference. The recorded optical data is then processed to extract three dimensions of surface motion. Axial velocity is measured by demodulating the received time-varying intensity of high amplitude pixels. Tilt, a gradient of surface velocity, is calculated by measuring speckle translation following reconstruction of the speckle pattern from the mixed signal.

摘要： A fragmentation pattern is formed on a surface of a warhead using a lithographic process. A photoresistant material is coated on an interior surface of the warhead casing. A portion of the photoresistant material is selectively cured by projecting an image of the fragmentation pattern onto the photoresistant material. The uncured portion of the photoresistant material is removed and an etchant is applied to the exposed portion of the warhead casing surface thereby etching the fragmentation pattern. Alternatively, a protective coating is applied over the entire surface thereby creating the fragmentation pattern.
