The present invention provides a System and Method to Define, Validate and Extract Data for Predictive Models. A system of sensors is deployed in an environment, with additional sensors for ambient data whose output as a form of metadata can characterize performance conditions including background ambient conditions. A format or sequence of processes is the basis for a math model to establish a logical weight to data for predictive modeling and event reporting. The present invention provides a computer or other sensor interface system with a primary sensor or sensors, network connection, and supplementary sensors to measure the conditions in which the primary data is captured. A software process allows for user inputs of data in order to establish the methods and rules for normal function.

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. The digital signal processing system performs matched filtering of the electrical signal received from the optical detector and additionally controls the functionality of the photonic energy source, the optical emission processing system and the received light optical processing system.

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.
