Abstract: The invention comprises a curved fluidic device and a housing piece with a curved slot to accommodate the curved fluidic device. The aim angle can be varied greatly by changing the depth of insertion of the fluidic device into the curved slot. By adjusting the curvature of the fluidic device and slot, the amount of variation possible and sensitivity to insertion depth can be controlled. With more curvature, the aim angle can be adjusted more but is more sensitive to insertion depth tolerance. With less curvature, the insertion depth is more robust but the aim adjustment range is smaller.

A synthesis method is also proposed for synthesizing the output-mask controller 211 and the set/reset controller.

Abstract: Data packets are selected for simultaneous transmission to multiple users using a transmitter with limited transmission power by first establishing transmission power requirements for each user, receiving in a queue a plurality of data packets for transmission to one or more users, and selecting one or more data packets for transmission in a composite burst with cumulative power for the selective packets not exceeding the limited transmission power. Data packets are selected for sequential composite bursts until all data packets in the queue have been transmitted, at which time transmission ceases until more incoming packets arrive at the queue. In selecting data packets for transmission, data packets which have previously been delayed in transmission can be given priority as well as priority based on quality of service subscribed by each user. Additionally a predetermined priority weight can be assigned to data packets and used for selection.

Abstract: An oxygen-based biomass solid fuel combustion system and method has an air separator for separating oxygen from air providing a supply of oxygen for feeding oxygen to a solid fuel combustion chamber. An airlock feeds a metered amount of solid fuel to the solid fuel combustion chamber. A burner stage having a firetube for collecting fuel gases from the solid fuel combustion chamber combusts the collected fuel gases with further oxygen from the separator and heats a boiler to generate steam. A heat utilization device (e.g. an electrical generator) may be connected to the steam boiler. Nitrogen-free diluent gases (e.g. argon and carbon dioxide) are used to control combustion process temperatures. The usable heat energy and useful byproducts are extracted from the different stages of the process.

Abstract: A method and apparatus for providing ordered capture clocks to detect or locate faults within N clock domains and faults crossing any two clock domains in an integrated circuit or circuit assembly in self-test or scan-test mode, where N>1 and each domain has a plurality of scan cells. The method and apparatus allows generating and loading N pseudorandom or predetermined stimuli to all the scan cells within the N clock domains in the integrated circuit or circuit assembly during the shift operation, applying an ordered sequence of capture clocks to all the scan cells within the N clock domains during the capture operation, compacting or comparing N output responses of all the scan cells for analysis during the compact/compare operation, and repeating the above process until a predetermined limiting criteria is reached. A computer-aided design (CAD) system is further developed to realize the method and synthesize the apparatus.

A ring segment BIP is composed of the path BIP error counts of multiple SONET/SDH paths from the ring segment input to the ring segment output.

Abstract: A reversing chamber oscillator has an oscillation chamber with a reversing wall, a centrally located power nozzle for issuing a jet of liquid toward the reversing wall, and a pair of liquid passages from the reversing chamber on each side of the power nozzle, respectively, for alternately issuing periodic pulses of liquid. The outlet passages are smoothly extended to intersect directly at a common outlet and are dimensioned and angulated relative to each other to control the sweep angle of a liquid jet which is periodically swept in the common outlet and issued to ambient. The pair of fluid passages have an upstream end at the reversing chamber and a downstream end at the common outlet and each passage has an outer wall which, with the reversing wall, define an oval.

Abstract: A solid fuel fed combustor method having a first chamber portion with an inlet feeding a metered amount of a solid fuel to a first burner stage having a first traveling conveyor firebelt. A metered amount of air is introduced in progressively increasing proportions along the length thereof to cause endothermic reduction of the solid fuel. The first stage feeds a second burner stage having a second traveling conveyor firebelt. Air is introduced in a progressively decreasing amount along the length of the second traveling conveyor firebelt to induce exothermic combustion and decomposition of fuel. The amount of air introduced and speed of the conveyors are controlled to minimize the quantity of carbon monoxide and nitrogen oxides and other pollutants. Radiative energy generated from fuel traveling on the traveling conveyor firebelts is reflected on fuel traveling on the first firebelt.

Abstract: A method and apparatus for providing ordered capture clocks to detect or locate faults within N clock domains and faults crossing any two clock domains in a scan-based integrated circuit or circuit assembly in self-test or scan-test mode, where N>1 and each domain has a plurality of scan cells. The method and apparatus will apply an ordered sequence of capture clocks to all scan cells within N clock domains where one or more capture clocks must contain one or more shift clock pulses during the capture operation.

Abstract: Methods of molding fluidic oscillator device having at least a power nozzle for projecting a jet of liquid into an interaction region with an upstream end, opposing side walls, opposing top and bottom walls, and a pair of control ports at the upstream end. The side walls diverge from the power nozzle. A mold cavity is provided in which the power nozzle, interaction region (IR) and control ports can be molded as a core without any seam lines. For a crossover type IR in which the upstream ends diverge and the downstream ends converge to a common throat area and coupled to an outlet aperture, a further mold cavity is provided in which the converging portion of the crossover type interaction region is formed as a second core having a joinder line to the first the core which is transverse to the direction of liquid flow in the fluidic.

Abstract: A full coverage area spray device has an oscillation chamber. Chamber end plates have a diameter D and the distance between the inlet and outlet apertures is L and ratio L/D determines the spray pattern and is adapted to support a basic toroidal flow pattern that remains captive within the confines of the oscillation chamber. The toroid spins about its cross-sectional axis and being supplied energy from the jet of liquid issued into the oscillation chamber. The toroidal flow pattern has diametrically opposed cross-sections which alternate in size to cause the jet to move in radial paths and also in tangential direction and thereby choose a different radial path at each sweep, whereby there is a random sweeping of the jet issuing from the outlet aperture over the area.

Abstract: An apparatus and method for guiding a surgical instrument within and around the human body. The invention employs a light emitter and an array of light sensors and a display to accurately locate an anatomical feature into which the light emitter has been placed. Laser or LED light emitted from an emitter, conveyed by a light conduit, is detected after passing through a thickness of bone and/or soft tissue by the sensor array. The signal from the sensor array is processed-and information indicating the relative direction of the emitter from the sensor is displayed. The light can be directed by a mirror or by bending the end of the light conduit.
