Abstract: In a computed tomography imaging system, wherein a longitudinally-unbounded object is oriented with respect to a source of cone beam radiation and a detector array, a method is provided for reconstructing an image of the longitudinally-unbounded object. Initially, relative movement between a longitudinally-unbounded object and the cone beam source is established along at least one circular scan path and at least one linear component. The cone beam is operated to irradiate measurable regions of the object while a prescribed orbit is traversed, to project an image of the longitudinally-unbounded object as cone beam data, onto the detector array. A scan field of view is defined, relative to the cone beam geometry. An error propagation distance in a Z direction is determined for the scan. The definition of the scan field of view is then modified, according to error propagation distance, and a set of image reconstruction data is generated, within the modified field of view, from the circular and linear scan paths.

Abstract: The present invention analyses an existing legacy system, such as a Physician's Office Management System, and automatically extracts, reformats and sends required data to a service company, which may be for example, an insurance company. It begins by feeding the legacy system "seed data" and monitors the legacy system storage device to determine a "raw map" of where and how the seed data is stored. It then culls out multiple records, single records, inconsistent records in the raw map. Control flow information is also extracted. This indicates which fields are "key" fields and are used to extract other information. These key fields must be acquired before their related data. After the data is located and the order is determined, a script is automatically created to extract the data. The data is then extracted and reformatted in a predetermined format determined by the service company, and the required data is automatically sent, by conventional means, to the service company.

Abstract: A direct sequence spread spectrum receiver samples an incoming signal and stores the sample in memory. Prior to sampling and storage, the incoming signal is translated to an IF signal. Also prior to storage, the IF signal is corrected for a frequency offset signal. The frequency offset may be caused by many sources, Doppler shift or local oscillator error, for example. Once the signal is corrected for the frequency offset, the signal sample is stored in memory. The signal sample is read from memory as necessary to process the signal. Such a receiver is useful in global positioning satellite (GPS) signal processing where the incoming signal contains several satellite transmissions encoded with CDMA encoding.

Abstract: A method for providing thermal protection for forced air cooled power electronic semiconductors without direct measurement of semiconductor temperature, the semiconductors being mounted on a heat sink over which cooling air is blown includes the steps of computing the cooling air mass flow rate, creating an electronic model of the semiconductor/heat sink combination and estimating the semiconductor junction temperature from the mass flow rate and model. The cooling mass flow rate is determined by measuring the temperature of the cooling air prior to passage over the heat sink, measuring atmospheric pressure of the cooling air, determining the volumetric air flow rate of the cooling air and computing, from the cooling air temperature, pressure and volumetric flow rate, the cooling air mass flow rate. Power dissipation in the semiconductors is then commuted and heat sink and semiconductor temperatures are estimated from power dissipation and cooling air mass flow rate. Semiconductor power dissipation is limited so as to restrict semiconductor temperature to a safe operating value.

Abstract: An electrical interconnection system (100) comprises a variable frequency rotary transformer (102) and a control system (104). The control system (104) adjusts an angular position of the rotary transformer (102) so that mesured power (P1) transferred from a first electrical system (22) to a second electrical system (24) matches an inputted order power (Po). The rotary transformer (102) comprises a rotor assembly (110) and a stator (112), with the control system (104) adjusting a time integral of rotor speed over time. The control system (104) includes a first control unit (107) and a second control unit (108). The first control unit (107) compares the input order power (Po) to the measured power (P1) to generate a requested angular velocity signal omega o. The second control unit (108) compares the requested angular velocity signal omega o to a measured angular velocity signal omega r of the rotary transformer to generate a converter drive signal (To) to a torque control unit (106), thereby controlling the angular positioning ( theta r) of the rotor assembly (110) relative to the stator (112). In various embodiments, the torque control unit (106) is integrated in the rotor assembly (110) and stator (112) of the rotary transformer (102).

Abstract: A spacer (18) includes a plurality of ferrules (22) welded to one another to form a structural integral matrix for locating fuel rods (12) in a fuel bundle. Each ferrule (22) has a pair of stops (26) along one side of the ferrule (22) and a central opening (30) along its opposite side. An elongated flat spring (24) having openings (54) straddling a central cross-piece (48) is disposed along an outer edge of the ferrule with the spring openings (54) receiving band portions (32) of the ferrule above and below the opening (30) through the ferrule. The intermediate cross-piece (48) bears against an adjoining ferrule whereby the end portions (44) of the spring bear against the rod (12) in the one ferrule, biasing it against the opposite stops (26). Thus ferrule/spring construction reduces the quantity of material of the ferrule, thereby improving performance without sacrificing structural integrity.

Abstract: A spray tower (114) is provided for removing gases and particulate matter from flue gases which are produced by processing operations of the type carried out in utility and industrial facilities. The spray tower is configured so as to minimize its overall height, such that construction, operational and maintenance costs of the tower are also minimized. A tank (130) located at the base of the tower serves as a reservoir for an alkaline slurry used to remove gases and particulate matter from the flue gases. The slurry is pumped from the tank to spraying devices (116, 118) located within the tower. An inlet (112) is located above the tank through which the flue gases are introduced into the tower. Disposed within the tower and adjacent the inlet is an enclosure (128) having an upper end joined to the tower and a lower end defining an opening. Spraying devices are located within the enclosure, preferably at approximately the same height as the inlet, so as to enable the overall height of the tower to be reduced.

Abstract: The limestone dissolution rate for limestone-containing slurries used in wet flue gas desulfurization (WFGD) systems is enhanced by the addition of ammonium ions. The ammonium ions may be obtained by incorporating into the limestone-containing slurry gaseous or aqueous ammonia and/or a water-soluble ammonium salt, such as ammonium sulfate, ammonium chloride, or ammonium carbonate. Increasing the limestone dissolution rate for limestone-containing slurries used in WFGD systems allows courser limestone particles, lower limestone stoichiometry and lower slurry recycle rates to be employed, thereby saving capital and operating costs. The ammonium ions may be recovered and reused in the process.
