Title: Inductive loop road vehicle detector with automatic adjustment - has controlled counter to modify capacitance of parallel tuned circuit to compensate for e.g. temperature and humidity disturbances
Inventor: KOMPART REINHARD
IPC: G08G1/042
Filed: 1977-04-05
Abstract: An inductive sensing unit is used to modify the frequency of an oscillator when a road vehicle passes through the field. An additional circuit stage ambient disturbances e.g. temperature, humidity etc. The output of a constant frequency oscillator (1) drives a parallel tuned circuit (2) consisting of a capacitor and the inductance of the vehicle detecting loop which is tuned to the oscillator frequency. The phase different between the oscillator and the tuned circuit signals is measured by a phase discriminator (3) whose output is amplified (4). The amplified output is fed to a window discriminator (12) and to an operating circuit (5-9). The window discriminator is via an operating circuit dependent compensation inhibitor (15) and an operating influent cing delay circuit (14) to a digital compensating unit (10). The latter connects discrete capacitors (14) across the timed circuit.

Title: Automatic recognition of phase keyed signals - storing differences between consecutive phases from digital channel filters in form of histogram from which various parameters are derived
Inventor: LIEDTKE FERDINAND DIPL ING
IPC: H04L27/00
Filed: 1977-11-24
Abstract: The received phase keyed signal is complex demodulated and digitalised, and the complex base band signal components are filtered through digital channel filters with different bandwidths but the same centre frequency signal amplitude and phase is measured for each channel. The clock pulse times at which the amplitudes are measured and instantaneous phases determined are obtained from the amplitude values of their square by narrow band filtering. The differences between two consecutive phases in each channel are stored in the form of a histogram, from which the phase keying, the number of phase states, receiver tuning conditions and the approx. cycle rate in real time are recognized. These parameters are determined by cross-modulation with modulation matched reference functions and testing the amplitude of the filtered out clock signal.
