Abstract: A method and apparatus for flexibly filtering upstream scheduling messages in a communication system is described. The inventive method and apparatus uses software to rapidly filter a MAP message comprising a plurality of information elements. In accordance with the inventive method, a communication device inputs a MAP message and outputs a filtered MAP message comprising upstream transmission information relevant only to the communication device. The communication device stores data relevant to its upstream transmit opportunities. This data is derived from information elements that are associated with the communication device. In one embodiment, the communication device stores a transmit time. In another embodiment, the communication device stores a transmit time and a transmit duration. In yet another embodiment, the communication device stores a transmit time, a transmit duration and an IUC.

Abstract: An apparatus for producing a radionuclide includes a target chamber, a particle beam source operatively aligned with the target chamber, and a regenerative turbine pump for circulating a target fluid through the target chamber via first and second liquid transports. During bombardment of the target liquid in the target chamber by the particle beam source, the target liquid is prevented from reaching vaporization due to the elevated pressure within the target chamber and/or the rapid flow rate through the target chamber. A cooling system can be provided to circulate coolant to the first and second liquid transport conduits, the target chamber and the pump to ensure that the target liquid is cooled upon recirculation back into the target chamber.

Abstract: This invention provides a method for designing a waveguide profile based upon predicted performance measurements of the waveguide. The method involves establishing a design metric, such as the change in acoustic reactance along the transition of the waveguide. Initial values may then assigned for the radius or diameter of the throat of the waveguide as well as values for the initial slope of the waveguide along the major and minor (or x and y) axis and the depth of the waveguide. The waveguide may then be divided into two or more sections. The values of the slopes for each section are then altered based upon the design metric. When using the change of acoustic reactance as the design metric, the slope of each section of the waveguide is adjusted to minimize the change in acoustic reactance between the sections, which is the desired performance standard.

Abstract: The present invention discloses methods, apparatuses, and systems for eliminating auto- and cross-correlation in weak signal CDMA systems, such as GPS systems. The invention uses parallel data paths that allow standard correlation of signals in parallel with verification of the lock signal to determine whether the system has locked onto the proper signal within the scanned signal window. The invention can be made with multiple CPUs, a single CPU with dual input modes, on multiple IC chips, or as a single IC chip solution for small, low cost reception, downconversion, correlation, and verification systems.

Abstract: A computer implemented method to estimate a respondent's or a set of respondents' rank order with respect to a number of attribute options (i.e. alternative prices, features, benefits, ways of expressing benefits, brand names, slogans, logos, graphic treatments such as package design elements and any other stimuli that the researcher believes may influence the individual's opinion such as a statement, graphic or brief audio). The method can be used when the number of stimuli to be presented exceeds the number that can be presented at one time to a respondent, most typically, exceeding the number that can be legibly displayed on one computer screen for rank ordering by a respondent. The estimated rank order is highly accurate, especially for the highest ranked stimuli, but requires only a small fraction of the respondent input that would be needed to capture a complete rank order from that respondent.

Abstract: The invention is a suspension element having an outer edge and an inner edge. The suspension element, such as a spider or surround, varies in shape along at least a portion of the suspension element to help relieve both the radial and tangential stress placed on the suspension element when it is stretched. The shape employed in the suspension element allows the suspension element to stretch more easily, creating a higher performance speaker of the same size by increasing the diaphragm excursion and voice coil movement.

Abstract: An edge-driven diaphragm loudspeaker driver is configured such that the suspension system of the driver is connected to the voice coil rather than to the diaphragm. Thus, the diaphragm in the loudspeaker is free of suspension systems connected to or extending from the diaphragm. By attaching the surround suspension to the voice coil rather than to the diaphragm, the diaphragm is isolated from the influence of spurious high frequency vibrations in the suspension system, thereby increasing the performance of the loudspeaker at high frequencies. The loudspeaker driver configuration also provides for a longer excursion range for the voice coil/diaphragm assembly, which allows for the driver components to be more accurately aligned during manufacturing, thereby enabling the loudspeaker driver to operate as a full range unit by producing low output frequencies.

Abstract: An apparatus for producing a radionuclide includes a target chamber including a beam strike region for containing a liquid and a condenser region for containing a vapor. A particle beam source is operatively aligned with the beam strike region, and a lower liquid conduit communicates with the beam strike region. The condenser region is disposed above the beam strike region in fluid communication therewith for receiving heat energy from the beam strike region and transferring condensate to the beam strike region. The lower liquid conduit transfers liquid to and from the beam strike region. In operation, the target chamber acts as a thermosyphon that is self-regulating in response to heat energy deposited by the particle beam source. A portion of the liquid expands into the lower liquid conduit prior to boiling. After boiling begins, a vapor void is created above the liquid and an evaporation/condensation cycle is established, with additional liquid being displaced into the lower liquid conduit.
