Title: Antenna which assures high speed data transmission connections between satellites and between satellites and ground stations
Inventor: RUSSO PASQUALE
IPC: H01Q21/22
Filed: 1991-05-23
Abstract: Antenna composed of a number of subarray radiating elements, according to an aperiodical geometry, which assures connections between satellites and between satellites and ground stations. The invention offers substantially advantages on previous techniques, essentially due to its aperiodical structure, through which it is possible to eliminate possible interference acting on the connection. In fact the possible presence of the array grating lobes during the array beam(s) steering in the angular sector of interest is reduced, i.e. the presence of a grating lobe within the field of view which can cause interference with another low orbiting satellite is avoided, so as to improve reception quality characteristics. The invention belongs to the field of microwave antennas and can preferably be employed in space-borne systems, due to its capacity to solve the problem of eliminating the presence of grating lobes in the field of view. This invention can be adopted even in mobile, fixed, civil and military radar systems. The antenna is essentially formed by a subarray structure having an aperiodical array configuration.
Patent CA-2066189-A1 (CA)
Inventor: HUGHES TIMOTHY C
IPC: G11B5/588
Filed: 1990-11-06
Abstract: In a servo tracking method and apparatus, a servo head (S) of a helical scan recorder (30) endeavors to travel equidistant between two servo signal-bearing stripes recorded on the tape (32). The recorder (30) determines a reference-crossing time at which the servo head (S) begins to cross a horizontal reference line (606) drawn with respect to the beginning of a stripe on the tape (32). The servo head (S) samples the amplitude of a servo signal provided on the tape (32) at a plurality of predetermined times after the reference-crossing time. A servo tracking circuit (175) uses the amplitudes of the servo signal at the predetermined sampling times to determine how to adjust the position of said head (S) relative to the pitch of said stripe.

Title: Pick-up device for loads
Inventor: NIJENHUIS DERK
IPC: B66F19/00
Filed: 1991-02-25
Abstract: An improvement has been invented for a pick-up device for loads, having means for engaging on the load and lifting it at one end over a low height, with one or more rollers so that the load can then be shifted with the pick-up device relative to a bearing face over which the rollers can move bearing the load. The improvement means that the engagement devices (6) can engage on the load (7) at a distance from the axis (17) of the rollers (3), and that the device (1) has engagement devices (4) for a flexible pulling element (22) such as a cable or chain, in order to move the load (7) with said pick-up device (1) over said bearing face, which engagement devices (4) for said pulling element are also situated at a distance from the axis (17) of the rollers (3), in such a way that the pulling force of a pulling element (22) engaging thereon tries to swing the pick-up device (1) relative to the rollers (3) in the direction in which the load (7) is thus being lifted. Said engagement devices (6) preferably engage in a pivoting manner on the further device (1) with bearings for the rollers on an eccentric shaft (18) lying parallel to the axis (17) of the rollers (3) and at a distance from them between said axis (17) and the engagement point on the load (7), while a cam (15, 16) is fitted both on said further device (1) and on said engagement devices (6), said cams being placed in such a way that when, under the influence of the pulling element (22), said further device is rotated about the axis (17) of the rollers (3) in the direction of lifting of the load (7) said cams (15, 16) come out of a position at a distance from each other into contact with each other. As a result of this improvement, the load is lifted first of all with one and the same pulling element, following which it is moved onto the bearing face with increasing driving force of the pulling element.

Title: Image processing apparatus with improved date conversion testing
Inventor: WARREN PAUL
IPC: H04N1/60
Filed: 1992-09-21
Abstract: ABSTRACT      Image processing  apparatus  comprises  a  first memory (100) for storing a plurality of data words corresponding to different pixels of a test image, each data word being set to a common test data value. The data words are converted into one or more analogue video signals using an digital to analogue convertor (110). The one or more video signals are converted,  using an analogue  to digital  convertor  (140), into captured data values with each captured data value corresponding to a different one of the data words stored in the first memory (100). The captured data values are stored in a second memory (150)  and averaged to generate a mean captured value.  Any difference between the mean captured value and the test data value is determined to identify any amplification error in the captured data values. First and second tolerance values are set to be respectively greater than and less than the mean captured value.  The captured data values between the first and second tolerance limits are then counted to identify any quantization errors in the captured data values.

Abstract: An unknown handwritten symbol written on a digitizing tablet is compared with symbols in a predefined "alphabet" or library of model symbols andthe closest match chosen. Recognition is independent of the size, position or orientation of the symbols. The alphabet can be any collection of symbols, such as alphanumeric characters, ideograms or words in cursive script and is created by writing at least one example of each symbol on the tablet.  A sequence of samples of the pen position is recorded while a symbol is being written.  The samples form a vector, which is then translated so that the centroid of the symbol lies at an origin. The comparison, which can easily be done in real time, involves calculating a correlation factor from scalar products of the vector for the unknown symbol andtwo versions of the vector for each model symbol and choosing the model symbol having the highest correlation factor.  If needed to distinguish between model symbols with similar correlation factors, the comparison can also include calculating a rotation factor from such vectors for use in making such choice. Embodiments of the invention can be configured that are user-independent, user-dependent or that evolve from one to the other.
