摘要:
A method and system for using input signal quality in an automatic speech recognition system. The method includes measuring the quality of an input signal into a speech recognition system and varying a rejection threshold of the speech recognition system at runtime in dependence on the measurement of the input signal quality. If the measurement of the input signal quality is low, the rejection threshold is reduced and, if the measurement of the input signal quality is high, the rejection threshold is increased. The measurement of the input signal quality may be based on one or more of the measurements of signal-to-noise ratio, loudness, including clipping, and speech signal duration.

A laboratory device design particularly for a multiplate format that includes a manifold wherein the position of the plate is not a function of gasket compression or vacuum rate applied. In one embodiment, the device has a modular design, wherein one or more removable inserts, preferably with different functionalities can be positioned between a base component and a collar component. The particular insert(s) chosen depend on the desired sample preparation or assay to be carried out. The insert(s) are stacked and are positioned between the base and collar as a unit, so that the stack within the manifold does not move during evacuation of the vacuum chamber. The consistent position of the insert(s) facilitates using vacuum sample processing with automated liquid handlers.

An apparatus and method for communicating information within a network having one or more communication buses (5, 6, 7, 8), consisting of one or more elements (20, 30, 40) to maximise throughput and minimise CPU involvement by executing the following. Compare incoming message identifiers (14) against a set of predetermined identifiers (22). Transpose data sets (12) within the incoming message data frame and where necessary, save and/or transmit new frames as defined by operations dependent upon the incoming identifier. By utilising an optimal set of operands the memory requirement is satisfied by a minimal size of standard type.

A control device for use with an aerodynamic wing including a bar having a fixed trim adjustment located between the bar and the user. The invention also includes a stopper that permits the user to quickly adjust the range of available dynamic trim. Preferably, the stopper does not lock until it engages the control bar, allowing the user to slide it quickly and easily to the desired location. The control systems of the invention provide a safety depower function when the end of the fixed trim is secured to a safety line.

Filtration device suited for concentration of liquid samples, particularly biomolecules, and a method of concentrating, desalting, purifying and/or fractionating liquid samples. In certain embodiments the device includes a housing having a sample reservoir, and two substantially vertically oriented and spaced apart membranes disposed in the housing. An underdrain is associated with each membrane such that fluid passing through each membrane flows through a respective underdrain into a filtrate collection chamber. The fluid that does not pass through the membrane is collected in the retentate collection chamber, and can be recovered such as by a reverse spinning step, achieving recoveries greater than about 90%. The substantially vertical orientation of the membranes increases the available membrane area by at least 2.7 times the area available in a conventional filter device. The two-panel configuration also maintains more available membrane area in use during the last stages of filtration than a one-panel configuration.

A household oven comprises a housing defining a cooking cavity, a water supply, and a steam generator having an evaporation element fluidly coupled to the water supply and configured to generate steam for introduction into the cavity in response to water being supplied to the evaporation element. A fluid control element fluidly couples the water supply to the steam generator and is operable to supply a metered amount of water to the evaporation element.

A stabilizer is provided for stabilizing a rotary or progressive cavity pump suspended from production tubing in well casing. The stabilizer is connected between the production tubing and the pump. The stabilizer has a tubular body having a cylindrical wall and a longitudinal bore contiguous with the production tubing. A releasable sliding dog is disposed on the exterior of the tubular body and is operatively connected by a link to one or more pistons. Each piston is disposed in a piston housing that is in fluid communication with the bore of the tubular body. Circumferentially spaced-apart feet extend radially outwardly from the tubular body. In operation, actuating fluid pressure advances the pistons uphole, driving the sliding dog up one or more longitudinal outwardly extending ramps to brace against the casing, with the feet contacting the casing and bearing opposing reactive force. Preferably, the sliding dog and the feet form a three-point contact with the casing that arrests lateral movement in any direction. Under non-actuating pressure, upward drag on the sliding dog compresses the pistons, retracting the dog, and permitting removal of the stabilizer and pump.
摘要:
A system and method for measuring an animal includes a light source and an optical source. The light source, which is preferably an array of monochromatic light emitting diodes, at least partially backlights one or more of the animal's legs. The optical sensor or device, which is preferably a single dimension camera or charged-coupled device, opposes the light source and obtains an image that includes silhouettes of one or more legs of the animal. A processor, such as a computer with software and data storage, determines measurements, such as the approximate skeletal trunk length of the animal, from the silhouetted legs in the image. One or more first ultrasound transducers can be arranged to determine an approximate height of the pelvic region, and one or more second ultrasound transducers can be arranged to determine an approximate width of the pelvic region.

The present invention provides a method of isolating, maintaining, and/or enriching for stem or progenitor cells derived from diverse organ or tissue sources. The invention specifically teaches that these can be accomplished by the controlled use of subatmospheric oxygen culture, and that the precise oxygen level or levels must be determined empirically and/or by reference to physiologic levels within intact functioning organ or tissue.
