Abstract: The system and method of projectile flight management using a combination of radio frequency orthogonal interferometry for the long range navigation and guidance of one or more projectiles that does not need to be accurate all the way to the ground based on the use of larger artillery. The system provides for more accurate targeting, especially in GPS-denied and GPS-limited environments.

Abstract: A system and method for using coherent aggregated bandwidth over multiple transmissions for improved performance of precision guidance and positioning and of object tracking systems. Angular offset (Az/El) estimations are strongly impacted by interference between direct and (comparable amplitude) ground-reflected signals. In rough ground situations, there could be many ground reflected signals. Bandwidth aggregation as used herein achieves sharper range sidelobes and smaller magnitude multipath interference terms resulting in increasingly accurate interferometric results.

Abstract: A system for radiation imaging of objects within a target area utilizing echo signals from a target area such as a patch of seafloor or the anatomy of a body. Data is obtained by time domain measurements received at a plurality of transducers in either monostatic or bistatic mode. Using multidimensional interferometry and multidimensional Fourier transforms, the data is reconstructed in multiple temporal and spatial frequency domains with a unique reduced wavenumber characteristic that retains the resolution potential of a traditional synthetic aperture approach. The system is inherently robust in applications with significant transceiver motion and/or variations in the propagation characteristics of the surrounding medium.

Abstract: A musical device comprises a guitar with a neck and a plurality of strings. A pick-up produces electrical output signals related to the frequency and amplitude of vibration of at least one of the strings. An electronic musical effect generator is receptive of the electronic output signal for altering the frequency and amplitude to produce a musical effect. A strain gauge assembly for plurality of axes is disposed on the guitar neck to sense a plurality of axes of strain in that position during use of the instrument. A pick is actuatable by a user for initiating a note on the guitar. A second sensor senses the manual actuation pressure on the pick and another strain gauge assembly for a plurality of axes is disposed on the pick and generates a plurality of control signals corresponding to structural deflections generated during the use of the pick.
