Abstract: Disclosed is a method of and apparatus for generating a signal representative of aircraft gear altitude after the flare maneuver is initiated in an automatic landing procedure. In accordance with the invention, the gear altitude signal is produced by complementary filtering of the aircraft gear altitude signal and the aircraft inertial vertical acceleration signal, with the complementary filter frequency being varied so that the aircraft filtered gear altitude signal primarily is produced on the basis of the vertical inertial acceleration signals prior to the time at which the aircraft reaches the runway threshold and is primarily produced on the basis of the aircraft gear altitude signal after the aircraft crosses runway threshold. The result is the reduction of the filtered gear altitude signal variation that can be caused by irregular terrain along the landing approach path while maintaining signal sensitivity to runway slope and runway slope variation.

Abstract: In a modulation system responsive to a first sampled signal (31) of a first sampling rate for supplying a modulated analog signal to an amplifier having nonlinearities to make the amplifier produce an amplified output signal, a selector (72) selects the first sampled signal and a second sampled signal of a second sampling rate as a selected signal when supplied with first and second control signals, respectively. The second sampling rate is equal to 1/N (N: 2, 3, ...) of the first sampling rate. A processing arrangement (36) processes the selected signal with reference to a difference between the selected signal and an additional digital signal (35) to compensate for the nonlinearities to produce a processed signal. The processed signal is modulated into the modulated analog signal. The amplified output signal is demodulated and converted into the additional digital signal by a converter (40). A comparator (71) compares an absolute value of the difference with a threshold value and produces the first control signal when the absolute value is less than the threshold value. Otherwise, the second control signal is produced. A controller (78) may control a phase of a sampling signal supplied to the converter so that a quotient of the difference by a differential of the selected signal becomes equal to zero.

Abstract: Borehole surveying methods and apparatus for surveying the true longitudinal magnetic field within a substantially non-magnetic drill collar occupying the part of a borehole being surveyed, despite the collar being of insufficient length to provide longitudinal magnetic field measurements which are uncorrupted by the longitudinal magnetic influences of adjacent magnetic drill string and bottom-hole assembly components. A plurality of longitudinal magnetic field measurements are made by a static instrumentation package at fixed known longitudinal positions within the collar, or by a free-falling instrumentation package at known times or at known increments of time as the instrumentation package moves through the collar. These measurements provide a longitudinal-position-dependent series of magnetic field measurements BZ(z) which enable the true magnitude of the terrestial magnetic field BZe in the direction of the longitudinal axis of the borehole to be calculated on the basis that BZ(z) = BZe + E(z), where E(z) is the longitudinal-position-dependent longitudinal magnetic field error induced by the magnetism of the drill string and the bottom-hole assembly. Several different methods of calculation are described, including polar and non-polar magnetic error function models. The methods can be extended to a full survey of the borehole heading by contemporaneous measurements of two further magnetic fields in each of two mutually orthogonal axes each also orthogonal to the longitudinal axis, along with contemporaneous gravity vector component measurements in each of these three axes. Relevant methods are described, along with apparatus for carrying out the heading survey methods.

Abstract: The circuit arrangement comprises a transmitter (3) and a receiver (4), to which a radiation emitted by the transmitter (3) passes back after reflection on an object (7). In an initialisation process which occurs for the first time after the installation and thereafter at greater regular time intervals, the power of the transmitter (3) is increased until the reflection on a stationarily existing object (7) within the detection range leads to the evaluation circuit (5) following the receiver (4) being triggered. The power of the transmitter (3) is then slightly reduced again; the circuit arrangement returns to normal operation. It now has its optimum sensitivity at which stationarily existing objects (7) no longer cause faulty triggering actions but the greatest possible detection range is given for moving objects to be detected.

Abstract: An optical character recognition system which automatically reads handwritten characters and the like which do not have to be printed in a special format, utilizes a computer with memory into which digitized pixel information from a page containing characters to be recognized are entered. The characters are assigned fields and are processed and recognized one at a time. A bit map is formed in memory of the character in a matrix of rows and columns (x-y coordinates) representing the pixels of the pattern constituting the character. The bit map is thinned to form, in another area of memory, another bit map of pixels arranged also in a matrix of rows and columns in x-y coordinates, of the skeleton (along the center of the pattern of pixels) of the character bit map. The skeleton pixel matrix and the character bit map are encoded into a plurality of recognition tables each with a string of codes. The table derived from the skeleton pixel matrix describes, with connection codes, the internal structure, row by row in accordance with the relative position of pixels in adjacent rows. Recognition tables derived from the pattern bit map and from the skeleton pixel matrix describe the character in terms of the relative position of the pixels along the borders of the character and provide a plurality of recognition strings, one in each table, for the front and rearviews of the character and for the shape of the holes in the character which are opened from the top (as in the numeral four) or opened from the bottom (as in the numeral seven). The recognition table derived from the skeleton pixel matrix is generated by reducing the connection codes to single codes for each line which embrace and characterize generally, rather than specifically, the connection codes for that row. From the recognition tables, the characters are recognized by searching recognition files containing blocks of successions of lines of code corresponding selectively for the codes in the recognition tables. The recognition file is arranged in hierarchal order so that the blocks in the file which represent characters having the lowest level of recognition difficulty in the character set to be recognized are searched first, the next highest level next and so forth. Generally, but not exclusively, the search for each character in the set is headed by a search through a block in the recognition file which excludes that character so that recognition can proceed to the blocks for the next character in the group of blocks for the same difficulty of recognition level or to blocks for the next level of recognition difficulty. In this manner characters are recognized with a high degree of reliability and an indication of failure to recognize the character occurs rather than misrecognition.

Abstract: In a motor with permanent magnets and a motor system, the value α produced by dividing, by the induced voltage constant ke, the product of the inductance Lm of the motor itself or the inductance Ls of the motor system in the d-q coordinate system is selected to meet a predetermined condition. The range of rotational speeds in which the motor can be operated while maintaining a predetermined output (B)under field weakening control can be widened. If a condition is established to determine a ratio (K) by which the rated rotational speed (A) under normal operating-conditions can be divided into a rotational speed (KA) under field weakening control, then conditions for a motor or a motor system that can be used can be determined.
