Abstract: The present invention provides a motion analysis system for measuring the relative function of one anatomical structure to another based on multiple accelerometer axis data, where the components of hard and soft tissue are used in analysis and where the data can be compared in a time series such that probabilities of involvement with various tissues can be correlated to the accelerometer data. The invention measures acceleration at various positions and can relate the data to various muscle and other soft tissue variations within the constraints of the anatomy and physiology including motion in three dimensional space, including rotations and translations and any functions including velocity and displacement.

Abstract: An optical system for performing a spectral analysis of test samples is provided. The optical system comprises a photonic energy source, an optical emission processing system, a received light optical processing system, an optical detector and a digital signal processing system. The optical emission processing system transmits one or more illumination wavelengths to a test sample. The received light optical processing system collects and isolates one or more wavelengths received from the test sample and transmits them to an optical detector. The optical detector converts the isolated one or more wavelengths of received electromagnetic radiation into an electrical signal which is transmitted to the digital signal processing system.

Abstract: A receiver with reduced near field noise is described. The receiver has a far range receiving section configured to sense a desired signal that includes near field noise. The receiver further includes a near range receiving section configured to sense a near field noise reference signal. An adaptive noise canceller (ANC) of the receiver is configured to detect the magnitude of an error vector from the far range receiving section. The ANC is configured to adjust the phase and gain of the near field noise reference signal in response to the magnitude of the error. Accordingly, the ANC can generate a corrected near field noise reference signal that is added to the desired signal with an adder. The near field noise is canceled by the addition of the corrected near field noise signal. The ANC uses a least mean square technique to determine the amount of correction needed.

Abstract: The present invention, generally speaking, provides an acoustic railway crossing detector. The present invention provides a means of not only detecting the presence of a train, but it can determine speed and direction of travel. This allows a more adaptive control of the railway crossing gates and may reduce the nuisance factor of having the gate close too far in advance of the train reaching the crossing. It is also much less susceptible to false activation by natural causes or acts of vandalism. In accordance with one embodiment of the invention, an acoustic railway crossing detector includes at least one acoustic emitter; at least one acoustic detector; multiple reflectors arranged to reflect acoustic energy produced by an acoustic emitter toward an acoustic detector, and control circuitry coupled to an acoustic detector for producing an indication of whether or not a train is present.

Abstract: An apparatus and method for significantly increasing the coding gain of a system used for data communications while still maintaining a high code rate (net data rate/gross data rate) and throughput by using a concatenated coding arrangement wherein error correction capabilities are optimized, having an encoder for encoding data to be transmitted with a first code type to form an outer code which is capable of correcting burst errors and further detecting if the remaining data is error free, and for encoding the data and the outer code with a second code type to form an inner code which is capable of correcting random errors and detecting multiple bit errors.

Abstract: An arrangement for high speed data detection and clock recovery in a multi-level data signal is disclosed wherein the received signal wavform is sampled at periodic preselected locations and the samples so obtained are compared to set values representing the expected levels at those locations. In within a permitted tolerance range over a given window of time, an indication of the presence of data is determined. Futher, if such correlation is determined to occur at a periodic rate, symbol-timing (clock) recovery is also indicated. A further embodiment with a dual recovery capability is also disclosed and described.

Abstract: A communication system utilizing a plurality of receiving antenna which receive digital signals and process all of the received signals in the same trellis type decoder. Hamming weights are applied to each of the signals in accordance with the Viterbi algorithm with only the minimum Hamming weight for any one state transition path between any two levels in the trellis being retained. At the intersection of any two paths in the trellis, the path with the minimum Hamming weight is retained and the other path is discarded.
