    摘要: Disclosed are various embodiments of cross-wind turbines that are capable of providing high efficiencies over a wide range of wind velocities. An airfoil stator causes wind to accelerate along its surface and creates a low pressure area on the leading face of the rotor blade during the power stroke. A blocking stator blocks wind from impeding the movement of the rotor blades during the return cycle and directs wind onto the trailing face of the rotor blades during the power cycle. A large pressure differential is created between the leading face of the rotor blade and the trailing face of the rotor blade during the power cycle which creates a large amount of force that rotates the rotor blade about the central shaft. In some embodiments, gaps are provided between the inside edge of the rotor blade and a stationary shaft which vents wind collected by the rotor blade during certain portions of the rotation cycle. The vented wind increases the pressure on the trailing face of the rotor blades during the return cycle to further assist in the efficiency of this system.

    摘要: A single polynomial expander 22 is time multiplexed to produce firstly a modified syndrome polynomial T(x) and then an erasure located polynomial Λ(x). T(x) is supplied to a key equation solving unit 32 which solves the key equation to calculate an error locator polynomial σ(x) and an errata evaluator polynomial ω(x). These polynomials σ(x), Λ(x) and ω(x) form three inputs to polynomial evaluators 52-56 and a Forney block 62 for determining the location and magnitude of each symbol error and symbol erasure, allowing the received codeword to be corrected in a correction block 72. Optionally, a transform block 42 is provided to avoid unnecessary delay and improve throughput when decoding shortened codewords.

    摘要: A mobile platform is provided which has at least one component having an array of distributed piezoelectric transmitters and an associated array of distributed receivers. The receivers are configured to receive ultrasonic transmissions from the transmitters. Data from the receivers is stored in memory and processed through an algebraic reconstruction tomography algorithm which forms an image of the defect within the component. An algorithm is used to determine the position and size of the defect.

    摘要: A network layer bridge includes: plurality of ports for connection to different network segments, a first port and a second port for connection to respective first and second network segments; a memory for storing network layer addresses for nodes with corresponding port identifiers and data link layer addresses, and data link layer addresses of more than one type; and a unit for discovering corresponding port identifier and data link layer address for a network layer address. The bridge forwards a message from a first node to a second node when corresponding port identifiers and data link level addresses for both first and second nodes are stored in the memory; the message being addressed with the network layer address of the second node, and the network layer bridge directing the message through the corresponding port to the corresponding data link level address for the second node.

    摘要: A scanning tomography system has a gantry including a disk for supporting a X-ray source and detector array and rotatable about a central axis. Multiple scans are made to reduce the effects of motion artifacts and improve image quality. In addition, the detector array is supported by a suspension system and is movable about the focal spot of the X-ray source a small amount so that in one mode of operation the detector array can be shifted at a predetermined angle from one position to at least one other position during a scan so as to provide an increase in the number of unique X-ray paths so as to provide improved image quality. In a second mode of operation, the detector array can be offset from the center ray so as to provide a quarter of a detector offset.
