Abstract: The present invention provides a method for detecting and locating brachytherapy seeds using Singular Spectrum Analysis (SSA). The method exploits the presence of seed-specific repetitive echo signals in detecting seeds and determining their location. Radio frequency (rf) echo signals received from a scanned area of interest are converted to zero-mean envelope-detected signals and then processed using SSA to produce a spectral-power line (a P line). The P line indicates the relative likelihood of a seed being present. A colored P-mode image derived from a set of P lines is superimposed on a conventional ultrasound B-mode image to depict seed location.
Abstract: A system and method for determining the location of an x-ray source of an x-ray machine and adjusting grid lines in an anti-scatter grid are disclosed. An ideal beam path is obtained and is used to adjust grid lines in the anti-scatter grid. In one embodiment, the invention uses a source locator to locate the x-ray source, communicate this location to the said adjustable anti-scatter grid which could align the grid lines mechanically, by means of servos attached to the grid lines, to the ideal x-ray beam path. In other embodiment electrical currents are used to align grid lines with the beam source. By aligning the grid lines with the beam path, images with increased contrast and reduced noise can be produced.
Abstract: The present invention provides a true-scale, coordinate-matched, linked in real-time, dual three-dimensional/two-dimensional visual display/viewer. The display simultaneously shows a 3D digital image and an associated 2D digital image of a selected drawing. The display of the present invention allows a user to visualize an asset's location, surrounding environment and hazards and true scale structural details for interior or external structural scenes. Using the display and associated tools, the user can obtain real-time information of an environment, true-scale measurement, plan ingress/egress paths, shortest paths between points and the number of doorways in a structure and track objects within the displayed environment. The intelligence gained using the tools and 3D/2D display may be used and further manipulated by a single user or may be distributed to other users.
Abstract: A Sales-Chip Associator process permits a creator of a Sales-Chip to share the Sales-Chip with a receiving party. The process utilizes a Sales-Chip Database and a Sales-Chip Subscriber Database to facilitate chip sharing. A handler is used in the Associator process and determines if an association exists between the Sales-Chip and the receiving party. The handler also facilitates recalling an association after being established by the receiving party.
Abstract: A unique digital compression technology for increasing the information carrying capacity of a bandwidth limited communications path highway by using a combined coding and modulation technique. The inventive technology allows multiple independent modulated data streams to simultaneously and instantaneously share the same bandwidth without cross-channel interference. A matched filter is used to substantially reduce the error rate and utilizes a unique training method based on performing a spectral response test. An algorithm calculates the effect of the unique characteristics of the communications highway on the transmitted signal and generates an ideal signal stored in the matched filter for comparison with received signals.

Abstract: A portable device accessory is used to hold, grip or manipulate a portable device such as and not limited to mobile phones, MP3 players, portable entertainment/computing devices, and/or gaming devices. The accessory possesses two suctions cups connected by a neck and having an aperture for receiving a jack on earphone. Certain embodiments of the accessory will have tabs, ridges, groove and/or a space to receive earphones. The accessory permits a jack of earphones to be threaded through an aperture and the cord of the earphones to be wrapped around the accessory. The suction cups may be inverted to conceal the cord wrapped around a neck of the accessory and tabs may be used to hold inverted suction cups together.
Abstract: A Sales-Chip Relevance Alert extends the capability of the regenerating search engine by allowing users to become informed about relevant information that has changed to a second query or search request that is run after a first query or search request. The user can narrowly and specifically describe with a high degree of precision what is relevant and meaningful to the user and how the user is notified. The Alert provides a timely notice to the user about the relevant information change through user-defined means and user defined messages.
Abstract: An ultrasound system is provided which includes a therapy ultrasound transducer and a diagnostic ultrasound transducer and operates in accordance with a method to direct the application of the therapy ultrasound. The method includes operating the diagnostic ultrasound transducer to acquire a first ultrasound image; simultaneously operating the diagnostic ultrasound transducer and therapy ultrasound transducer for a second interval to acquire a second ultrasound image; and determining a difference in the first and second images indicative of the pattern of the therapy ultrasound transducer signal. The difference in the images, which result from enhanced non-linearities and propagation distortions induced by the high intensity therapy ultrasound, can be obtained by subtracting the two images.

Abstract: The auto-fastening skeg system comprises a skeg receiver and a skeg. The skeg has a male component that cooperates with a cavity of the skeg receiver. The cavity has front and rear ends, a spring disposed at said front end and at least one dowel disposed between the front and rear ends. The male component includes a front tip and at least one locking wedge, said locking wedge corresponds in number to the number of dowels. When the male component is set in the cavity and the locking wedge is aligned with the dowel of the receiver, the spring pushes the front tip of the male component against the rear wall of the cavity of the receiver and the locking wedge against the dowel providing a locking mechanism that holds the skeg to the receiver.

Abstract: A switching system for routing information packets that can simultaneously receive a variety of packet formats. The packet formats include electronic packet transmissions, optical wave division multiplexed data (WDM) with a single frame consisting of a plurality of packets to be sent to a common output line, with each packet traveling on a separate wavelength, WDM packets where the header of an individual packet travels on a wavelength different from the remainder of the packet (i.e. the payload) and the payload either travels on a single wavelength or is subdivided into a plurality of sub-packets with each sub-packet carried on a separate wavelength, and the like. The system includes input devices, a scheduling unit, a switching unit; and variable delay line units. A deconcentrator in the packet switching system creates a minimum gap between packets.
Abstract: The present invention is directed to a system and method for connecting attachments to a vehicle including in a first embodiment a bumper guard that provides a barrier of protection for vehicle bumpers. The bumper guard includes two pieces, a first piece or bumper guard locator and a second piece or bottom piece. The first piece is attached to a vehicle through the lower holes in a license plate and is secured or locked in place using a locking mechanism. The second piece attaches, or depends from the first piece and is dimensioned and configured to rest over a bumper of the vehicle. The second piece is removably connected to the first piece and may be replaced when damaged or worn. Alternatively, in a second embodiment of the invention, the second piece may be a different component such as a “tailgating platform tray”, or other component module that attaches to a “T” locking system. The bumper guard or platform tray can be easily attached to the vehicle, stored and removed.
