Abstract: Engine control systems utilize a number of potential control loop regimes optimized for particular engine conditions. These loops may relate to transient conditions or engine steady state. The choice of engine control loop is made by a selector by the error divergence between measured signals and reference signals. These reference signals generate adjustment demands for the engine. It is possible for the nature of the selector to select the steady state control loop prior to acquisition of the desired target performance criteria. The steady state control loop will take longer to achieve the optimum performance conditions. The present invention provides for a multiplier, such as squaring of the error divergence, in order to retain authority for the transient control loop control beyond the normal selector determined error divergence criteria.

Abstract: Systems and methods are provided for acquiring and reconstructing projection data using a computed tomography (CT) system having stationary distributed X-ray sources and detector arrays. In one embodiment, a non-sequential activation of X-ray source locations on an annular source is employed to acquire projection data.

In a further embodiment, a plurality of X-ray source locations on an annular source are activated such that the aggregated signals correspond to two or more sets of spatially interleaved helical scan data.

Abstract: Systems and methods are provided for reconstructing projection data that is mathematically complete or sufficient acquired using a computed tomography (CT) system. In one embodiment, a set of projection data representative of a sampled portion of a cylindrical surface is provided. The set of projection data is reconstructed using a suitable cone-beam reconstruction algorithm. In another embodiment, two or more sets of spatially interleaved helical projection data are processed using helical interpolation. The helically interpolated set of projection data is reconstructed using a two-dimensional axial reconstruction algorithm or a three-dimensional reconstruction algorithm.

Abstract: Flow control in a distributed switch fabric (100, 200) includes detecting at least one of a congestion condition (238) in a downstream transceiver port (205) and an oversubscribing condition (257) of a channel buffer (230), where the downstream transceiver port (205) and the channel buffer (230) both correspond to a channel (231) of a traffic manager (208). Packets begin accumulating in the channel buffer (230). Per-flow flow control (254) operates to modify transmission of the packets over the channel (231) to the channel buffer (230) if the channel buffer (230) reaches a threshold value (256). Link level flow control (252) operates transparently to the traffic manager (208) if the congestion condition (238) is detected and the channel buffer (230) fails to reach the threshold value (256).

Abstract: A fluid mover includes a rotor to transfer momentum with a fluid when operated at a given volumetric flow rate through the rotor. The rotor includes a plurality of enclosed passages to transfer momentum in or out of the fluid as the fluid passes through the enclosed passages in response to rotation of the rotor. The passages are formed with a cross sectional shape and cross sectional dimensions along their entire length sufficient to establish and maintain laminar flow of the fluid along the entire length of the enclosed passages when the fluid is passing through the rotor at the given volumetric flow rate. The fluid mover also includes a housing having at least one inlet and at least one outlet for the fluid.

Abstract: An archwire used during the course of orthodontic treatment has four generally flat sides that are arranged in the general shape of a rectangle. The four sides are connected by curved surfaces having a radius of curvature that is substantially larger than the corners of conventional archwires. The cross-sectional shape of the archwire facilitates insertion and removal of the archwire in orthodontic appliances such as brackets and also tends to reduce resistance to sliding movement of the appliances along the archwire.

Abstract: Embodiments of the present invention address deficiencies of the art in respect to managing the scatter and flood problem of the activity-centric computing environment and provide a method, system and computer program product for sorting and filtering activities in an activity-centric computing environment. In one embodiment of the invention, a method for filtering and sorting activity objects in an activity-centric computing environment can include generating at least one activity thread of hierarchically arranged activity objects, selecting at least one filtering criterion for the activity objects, and filtering the activity objects in the activity threads. Additionally, a filtered view of the activity objects can be generated in an activity map in the activity-centric computing environment.

Abstract: Fluid movers produce at least predominantly laminar flow internally in an axial or a radial direction in a rotor. A fluid mover rotor comprises a matrix of passages of appropriate size to produce at least predominantly laminar flow spaced circumferentially around the rotor. The passages may provide axial, radial or mixed flow. “Appropriate” dimensions may be selected for a specified volume flow rate. In a radial embodiment, a matrix of radially extending passages could comprise walls having an axial height projecting from an annular disk. The passages may be offset with respect to the radial direction to provide an angle of attack that minimizes incidence losses. The matrix structure allows the use of thin-walled passages to minimize blockage of entering air.
