摘要： A retro-directive antenna for communicating with a geostationary satellite autonomously detects the direction from which a signal is received, and transmits a beam that points back along the same direction. An array feed is used to illuminate a parabolic reflector. Each feed element of the retro-directive antenna is associated with a unique pointing direction of the beam in the far field. As the transmit energy is switched to different feed elements, the far-field beam is scanned, making it possible to track a geostationary satellite in a slightly inclined orbit. This eliminates the need for mechanical tracking and maintains high antenna gain in the direction of the geostationary satellite. The use of a toroidal reflector with multiple linear array feeds spaced in the azimuth direction enables multi-beam operation, allowing multiple geostationary satellites, spaced by up to fifteen beam widths in azimuth, to be tracked simultaneously and independently.

摘要： An adjunctive ultrasound mammography system and associated methods are described, comprising a scanning apparatus for facilitating standardized, repeatable breast ultrasound scans, and further comprising an adjunctive ultrasound display apparatus configured for fast, intuitive viewing of adjunctive ultrasound data concurrently with x-ray mammogram information. In one preferred embodiment, thick-slice ultrasound images are displayed near an x-ray mammogram such that a screening radiologist can quickly view the thick-slice images for assistance in interpreting the x-ray mammogram. Methods for concurrently acquiring and displaying vibrational resonance image (VDI) data are described. Computer-aided diagnosis (CAD) algorithms that incorporate acoustically-based feature vectors are described, the feature vectors including lateral shadow metrics, vertical shadow metrics, posterior enhancement metrics, and VDI-based metrics. Algorithms are also described that combine x-ray mammogram CAD results with adjunctive ultrasound CAD results without requiring complex image registrations therebetween. Many of the practical, economic, and political barriers to acceptance and integration of ultrasound mammography into existing mass breast cancer screening environments are mitigated.

摘要： An adjunctive ultrasound mammography system and associated methods are described comprising an adjunctive ultrasound display configured for quick, intuitive, interactive viewing of data derived from volumetric ultrasound scans, the data being displayed near a conventional x-ray mammogram display. Preferred embodiments for navigating among a thick-slice image array, a selected enlarged thick-slice image, and planar ultrasound views are described, including a preferred embodiment in which the planar ultrasound views are updated in real time as a cursor is moved across an active thick-slice image. In one preferred embodiment the thick-slice images are inverted prior to display, with non-breast areas of the image preferably segmented out and reset to dark. The inverted thick-slice images are of more familiar significance to radiologists having years of expertise in analyzing conventional x-ray mammograms. For example, the inverted thick-slice images allow benign features to be more easily dismissed as compared to non-inverted thick-slice images. Preferred embodiments for computing thick-slice image values from the volumetric scan data are also described that emphasize larger mass lesions in the resulting thick-slice images, and that compensate for mass lesions that straddle thick-slice region borders.

摘要： A finless projectile provides improved ease of use, aerodynamics, muzzle velocity, drag, target, and excursion accuracy, structural integrity, terminal effectiveness and safety, at lower cost. The finless projectile includes a slug, a forward projectile body, an aft projectile body, an obturator, and a pad. The finless projectile is a full bore projectile that defines a hollow core, but does not include a sabot nor does it carry explosives. The finless projectile functions by kinetic energy transfer from the projectile to the target by deforming the target. The center of gravity of the finless projectile is forward of the center of pressure to provide static stability to the finless projectile.

摘要： An advanced multiple-beam GPS receiving system is achieved that is capable of simultaneously tracking multiple GPS satellites independently, detecting multiple interference signals individually, and suppressing directional gain in the antenna pattern of each beam in the interference directions. The GPS receiving system can be used for both planar and non-planar receiving arrays, including arrays that are conformally applied to the surface of a platform such as an aircraft. The GPS receiver combines spatial filtering and acquisition code correlation for enhanced rejection of interfering sources. Enhanced gain in the direction of GPS satellites and the ability to shape the beam patterns to suppress gain in the direction of interfering sources make the GPS receiving system largely insensitive to interfering and jamming signals that plague conventional GPS receivers.

摘要： An instrument guide is described for mounting an invasive instrument such as a biopsy needle to an imaging probe, controlling its position, monitoring its position, and/or predictively displaying its position on a user display of the medical imaging system. A plurality of substantially rigid segments are hingeably connected to the probe, to an instrument handle, and to each other such that movement of the biopsy needle is restricted to within the imaged plane. However, substantial freedom of movement within the imaged plane is provided such that the instrument may be inserted into the patient over a wide range of angles. In one preferred embodiment, angle detectors are provided at each segment intersection and measurements provided for computing and displaying the instrument position and orientation on the user display. The instrument guide/position monitor is preferably made with low-cost components such that it is disposable after a single use. A predictive user display is provided in which the throw of a spring-loaded instrument is shown on the user display, the throw corresponding to the space that the instrument will occupy after a spring trigger is activated.

摘要： A system is provided that enhances the throughput and reliability of wireless communications by providing multi-beam user terminals that exhibit directional discrimination. Multiple wireless communication channels are matched with multiple beams created from an array antenna by a beam-forming processor. The multiple wireless communication channels are bonded into a single virtual channel, thereby increasing data bandwidth while reducing interference and multi-path effects that can degrade communications. The beam-forming function may be performed in a dedicated beam-forming processor or may reside within a general-purpose microprocessor located in the user terminal.
