Abstract: A method includes forming a conductive material on a first dielectric layer, exposing the conductive material to aniline to produce a passivated surface of the conductive material, and after exposing the conductive material to aniline, forming a second dielectric layer on the first dielectric layer using a deposition process. The deposition process is a water-free and plasma-free deposition process, and the second dielectric layer does not form on the passivated surface of the conductive material.

Abstract: A NAVSTAR receiver in which the received signals are processed to produce digitized quadrature signals at zero i.f. Baseband phasor rotation to effect Doppler tracking in the receiver loop is accomplished by deriving digital signals representing sin .omega.T and cos .omega.T for the required rotation angle .omega.T, multiplying the quadrature signals separately and summing the outputs according to the algorithm I.sup.1 =I cos .omega.T+Q sin .omega.T and Q.sup.1 =Q cos .omega.T-I sin .omega.T, where I & Q are the digitized quadrature signals.

Abstract: An intruder detector system employing Doppler radar consists of an encoder for modulating RF pulses with a cyclic pulse code, the code being cycled at a frequency equal to the RF pulse frequency and the pulses being modulated on a VHF carrier for transmission along one of a pair of parallel radiating cables. The signal received from the other cable is demodulated and digitized by a zero crossing detector functioning as a 1-bit analog-to-digital converter. A bank of exclusive-OR gates functioning as 1-bit correlators then simultaneously correlates each successive bit of the digitized signal with the values of the respective bits in each fixed position of the transmitted code sequence.
