IPC: G02B6/24

Abstract: A method of detecting a splice in an optical fiber in the presence of noise generates a nulling filter from a segment of a signal received from the optical filter by determining a set of coefficients having an initial "1" followed by p-1 "0" values and w i  finite impulse response filter values, where p is a prediction interval greater than the width of an expected splice signature. The received signal is processed by the nulling filter to remove exponentials from the received signal, leaving an error signal containing noise and splice information. The resulting error signal is processed by a correlation filter to reduce the noise in the error signal. The output from the correlation filter results in a noise reduced error signal with the splice appearing as a noticeable dip in the waveform. The waveform is passed through a threshold detector to identify the splice when the dip exceeds a predetermined threshold.

Abstract: The material separation process takes place by machine by comminuting (1) the objects (G) in the mixture so that particles of either non-metallic or metallic material are formed. The particle mixture is subsequently screened (2) of fine parts and then separated (5) electrostatically into a non-metallic (N) and a metallic (M) granulate fraction. The material separation takes place with a high degree of separation, i.e. pure granulate fractions (N) and (M) are produced with only small residual parts of the respective other material. Applications of the process on different kinds of piece goods made of composite material with non-metallic and non-magnetic metal portions are described, such as bottle tops, defective incandescent or fluorescent lamps, processing waste or manufacturing waste of composite materials, for example lined metal foil or aluminium sandwich plates. <IMAGE>

Abstract: For real time de-aliasing of the Doppler velocity data in a weather radar system uses a Process Radials routine (20) which processes every valid range gate along a radar dwell by determining if each range gate is within the Nyquist velocity of either the average of four preceding range gates or data from a Windfield Model. To further enhance the de-aliasing process a Process Dual Scans routine (16) is used prior to the Process Radial routine (20) to de-alias velocity data by comparing velocity data from two scans of different pulse repetition frequencies. Subsequent to the Process Radials routine (20), a Minimize Azimuthal Shear routine (22) checks velocity discontinuities from azimuth to azimuth. The de-aliased data is transferred to an Update Windfield Model routine (24) for quality checks of the de-aliased velocity data and updating of the Windfield Model. This complete method of de-aliasing the velocity data is performed during the real time operation of the radar system (30, Fig. 2A).
