Abstract: The Beamformer with Adaptive Processors is a practical joint spatial-templ processor suitable for combining multiple antenna signals for a communications receiver. The invention identifies a beam or beams, amongst a discreet set of fixed beams, for which adaptive locally optimum processing will most likely reveal the presence of a weak signal. The invention chooses a suitable form of adaptive locally optimum processing according to the nature of the beam or beams identified. The beam or beams are selected for adaptive locally optimum processing depending on several simple characteristics of a Fast Fourier Transform (FFT) of each beam's output. These are .SIGMA..sigma..sup.2, D, and B (the sum of the squares of the Fourier coefficients, the number of distinct peaks amongst these coefficients, and the total number of coefficients defining the peaks, respectively).

Abstract: Disclosed herein is an ignition system comprising a coil mounted on a core having first and second spaced legs, together with a rotor mounted for rotation, under normal operating conditions, in one direction relative to the core such that any point on the periphery of the rotor passes the first leg prior to the second leg. The rotor includes a magnet having arcuately spaced first and second poles and first and second pole shoes extending respectively from the first and second poles.
