Abstract: Methods, apparatus, and software for implementing dual Bayesian encoding-decoding for text-to-code transformations. In one aspect, a multi-model probabilistic source code model employing dual Bayesian encoder-decoder models is used to convert natural language (NL) inputs (aka requests) into source code. An NL input is processed to generate a Probabilistic Distribution (PD) of Source code (SC) tokens in an SC token sequence and a PD of Abstract Syntax Tree (AST) tokens in an AST token sequence, wherein each SC token is associated with a respective AST token, and each of the SC and AST tokens have a respective PD. One or more fixing rules are applied to one or more tokens SC tokens that are identified as needing fixing, wherein the fixing rule are selected in consideration of the PDs of the SC tokens and the PDs of their associated AST tokens.

Abstract: An embodiment in accordance with the present invention provides a device for whole-body plethysmography (WBP) of a mouse for the continuous characterization of sleep and breathing. The inherent limitations of standard WBP are addressed to enable the continuous recording of validated measures of tidal volume, tidal airflow, and respiratory effort surrogate in an unrestrained, unanesthetized mouse. The addition of standard EEG and EMG recording technology allows for respiratory patterns to be fully characterized during sleep and wakefulness. The present invention also allows for the demonstration of the development of dynamic upper airway obstruction [inspiratory flow limitation (IFL)] during sleep in a susceptible, obese murine strain.

Abstract: Methods for generating a directional sound environment include providing a headgear unit having a plurality of microphones thereon. A sound signal is detected from the plurality of microphones. A transfer function is applied to the sound signal to provide a transformed sound signal, and the transformed sound signal provides an approximation of free field hearing sound at a subject's ear inside the headgear unit.

Abstract: Monitoring the physiologic status of a human or animal subject includes detecting a blood vessel signal with a sensor. A physiologic time interval can be determined, and information related to the physiologic status of the subject can be analyzed and communicated.

Abstract: The present invention is a method and system for accurately analyzing shaft encoder signals from rotating machines. The invention reduces noise and other interferences in the encoder signals by novel means that yield an unprecedented power for extracting useful information. Signal distortion due to variation in the rotation rate of the machinery and due to FFT leakage are eliminated by acquiring digital values of the encoder signals at a set of discrete times that are determined by the properly averaged rotation rate of the shaft and requiring a fixed integer number of these discrete times per rotation of the shaft. Amplitude modulation is eliminated by proper spectral combination of left and right sidebands of the main encoder signal. Additive noise is removed by multiplying sidebands and averaging the results over a number of data records.

Abstract: The present invention provides a method and system for analyzing signals generated by rotating components that slip in a rotating machine and for detecting faults in those components. Pulses from a shaft encoder serve as an external clock in digitizing the signal data. A fixed number of data samples are thereby acquired for each complete rotation of the rotating shaft of the machine. Complex spectra are provided for data records of a fixed length with the first sample of each data record always beginning at the same point relative to the shaft angular orientation. Signal-processing means multiply pairs of signal spectral components so that the complex products produced by the data for the component of interest has a fixed phase relative to the shaft orientation.

Abstract: A magnetic chuck for use in grinding optical lenses consisting of a means for increasing or decreasing the magnetic force exerted by a magnetic attachment surface contained in a housing sized for use in a lens grinding machine, wherein the means for increasing or decreasing the magnetic force exerted by the magnetic attachment surface is operated by means of manually operating a control to rotate a permanent magnet 90 degrees from a first position to a second position, where in the first position the magnetic force exerted by the magnetic attachment surface is minimal and in the second position, a substantial increase of magnetic force is exerted by the magnetic attachment surface for secured attachment of the lens piece during grinding of a raw glass lens blank into an optical lens.

Abstract: An optical lens grinder device including a main base and a lens carriage pivotally slidably connected along one edge to the base. A first motor mounted on the base drives a pair of closely spaced apart grinder wheels, one for shaping and sizing a lens blank, the other for peripherally beveling the edges thereof.
