摘要： Systems are provided to derive a value of barometric pressure at a defined location in the atmosphere at a computed geometric height. By using the geometric height in a look-up table of pressure/height values representing a standard atmospheric profile, atmospheric deviation data indicative of the difference between measured and reference pressures at that atmospheric location (C) is derived. Ground-based interrogators (10,20) located at spaced positions are used to initiate response signals from airborne transponders commonly installed in transient aircraft (C). Using resulting range data based on round-trip timing differences in signals sent to (12,16) and received from (16,14) the airborne transponder (C), geometric analysis and computation is used (18) to determine the geometric height of the transponder representing a specific atmospheric location. The height, together with barometric pressure data transmitted by the airborne transponder, are used (28) for the look-up of reference pressure data and derivation of atmospheric deviation data for that atmospheric location. Systems and methods provide such data for inflight altimeter calibration, height determination, atmospheric pressure profile development, weather forecasting, transponder calibration and other purposes.

摘要： A switched capacitor integrator is used within the feedback loop of an automatic gain control (AGC) circuit to provide a very long time constant (5 minutes or more) when the amplitude of the gain-controlled signal is within predetermined limits. The time constant is automatically and quickly changed to a much shorter value when the gain-controlled signal is outside the predetermined limits, thereby allowing the AGC circuit to rapidly bring the gain-controlled signal amplitude within the desired range between the predetermined limits. Time constants of orders of magnitude longer than those readily realized with prior art methods of long time-constant filtering are achieved.

摘要： Disclosed is an antenna for radiating wave energy signals in three frequency bands. Signals having frequencies in the first and third bands are radiated by a first radiator. Signals having frequencies in the second, intermediate frequency band are radiated by a second radiator. The impedance characteristics of the radiators are used to selectively couple signals from the input to the appropriate radiator.

摘要： Disclosed is a system which electro-optically scans a set of color separations and processes the resulting signals in accordance with an electrical analog of an adjustable, halftone color reproduction process to develop a group of output signals which collectively represent the apparent color, in a given color representation system, of elemental areas of the actual composite color print that could be obtained from the set of color separations by means of the half-tone color reproduction process. The group of output signals is developed in such a form as to be readily utilizable in diverse forms of color image display apparatus for developing a displayed color image which simulates the aforementioned actual composite color print. Also disclosed is novel electro-optical apparatus useful in the above system for scanning simultaneously, in parallel, the four photographic transparencies of a four-color separation set. The electro-optical apparatus utilizes a bank of four lenses to simultaneously image the raster of a scanning light source onto each of four corresponding color separation transparencies which are positioned in a rectangular array in a common plane. The scanning light transmitted by each transparency is independently collected and detected to generate a set of output signals, each of which is representative of the transmissivity of successively scanned elemental areas of a corresponding one of the separation transparencies. The relative positions of the scanning light source, the bank of lenses and the set of color separations are readily adjustable, thereby permitting the apparatus to scan color separation transparency sets of different dimensions.

摘要： Disclosed is a system for receiving and detecting propagated mechanical-wave analog signals in which the analog signals are converted to a digital signal wherein pulse spacing is proportional to the corresponding instantaneous frequency of the detected mechanical wave signals. A digital processor compares the pulse-spacing of successive pulses of the incoming digital signal with selected pulse-spacing limits corresponding to the frequency limits of the selected bandwidth, and an output signal is generated indicating the receipt of analog signals within the selected frequency band whenever all of the successive pulses during a sampling interval lie within the selected pulse-spacing limits. Generation of an output signal is inhibited when any pair of successive pulses has a pulse spacing outside of the pulsespacing limits during the sampling interval.

摘要： Disclosed are systems for determining the true angular position of a target with respect to a reference location. One such system employs a novel array of antenna units at the reference location. The units are uniquely excited by a pulse type signal in two opposite predetermined sequences to produce a pair of radiated pulse trains. A target located in the field of this array is illuminated by these radiated pulse trains each of which has a phase distribution proportional to the angular position of the target with respect to the array and opposite in sense to that of the other. Furthermore, the frequency of each pulse train undergoes a doppler shift due to the radial velocity, if any, of the target with respect to the array and therefore the ambiguity due to such shifts can be compensated for by detecting the phase distribution of each pulse train and processing the information obtained. In this manner an indication of the target''s true angular position, free from doppler ambiguities, can be provided either at the reference location alone, the target alone, or at both the reference location and the target.

摘要： Disclosed is an improved wire guide assembly for multiple coil winding machines which have a laterally driven guide shaft. To permit precise lateral adjustment of the position of a wire guide support, an annular member is engaged on a threaded portion of the guide shaft and coupled to to the wire guide support means so that lateral movement of the annular member along the threaded portion of the shaft is translated into corresponding lateral movement of the wire guide support relative to the shaft and to a stationary multiple coil from. When used in conjunction with an improved index assembly, which is also disclosed, coil margin length and winding length can readily and accurately be determined and adjusted for different size coils.
