摘要： 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.

摘要： The present invention provides a system enabling the remote analysis of a fluid, wherein the analysis of the fluid and collection of data relating thereto can be provided at a plurality of remote locations by a plurality of remote devices. Each remote device is connected directly or indirectly to a central controller via one or more communication networks, thereby enabling centralised collection, evaluation and analysis of a plurality of data relating to characteristics of the fluid system being monitored. The system according to the present invention can further provide a means for the collection of strategic samples of fluid, for example, such that these samples can be collected from one or more of the remote locations at a later time for future and more detailed analysis at a laboratory or other facility. The fluid monitoring system provides a means for real time monitoring of a fluid at a plurality of locations together with a global view of the characteristics of a fluid system. In one embodiment of the invention, this fluid monitoring system can provide information and risk factors relating to real time change in the characteristics of a fluid and the fluid system.

摘要： 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.
