Patent EP-0449158-A2 (EP)
Inventor: LOSQUADRO GIACINTO
IPC: H01Q3/20
Filed: 1991-03-24
Abstract: System for fine pointing of reflector antennae, particularly suitable for space applications where such reflector (Figure 1) is moved within a spherical surface secor (5) with focus in the centre (F). Thus the beam can be pointed in the required direction and it ensures permanence in the focus, There are no defocussing losses even with a fixed feed system. 
     The system proposed achieves the required scan with low losses. 
     The feed beam at any rate covers a large part of the reflector surface (1), cosidering the usual edge taper values of the reflector of the order of 5 - 15 dB, i.e. the amplitude tapering due to the feed primary diagram, to the reflector edge and bearing in mind the range attenuation. 
     The feed (2) and related feed lines either in waveguide (10) or coaxial cable, are fixed and firm. This solves the feasibility problems which are often unsurmountable, required to reduce possible RF losses of articulated lines, also avoiding undesired modulation effects induced onto the signals. 
     The system is essentially made up of the following (Figure 2): 
A cardanic joint (3) (4); 
pressure spring(s); 
two actuation motors (7), equipped with position stops; 
two capstans (13) to widn and unwind piloting wires; 
two piloting wires (6).

Abstract: A method and related cryptographic processing apparatus for handling information packets that are to be cryptographically processed prior to transmission onto a communication network, or that are to be locally cryptographically processed and looped back to a node processor. A special cryptographic preamble is included in each information packet that is to be subject to cryptographic processing. The cryptographic preamble contains an offset value pointing to the starting location of information that is to be processed, and completely defines the type of cryptographic processing to be performed. The cryptographic processor can then perform the processing as specified in the preamble without regard to a specific protocol. If the packet is to be transmitted onto the network, the preamble is stripped from the packet after cryptographic processing, so that the formats of packets transmitted onto the network will be unaffected by the preamble. Cryptographic processing modes include encryption of data for outbound transmission, encryption of a cipher key for loopback to the node processor, encryption or decryption of data for loopback to the node processor, and computation of an integrity check value for loopback to the node processor.

Abstract: A photoprint mounting platen facilitates presentation of a photoprint to an imaging station of photoprint imaging scanner, in a secure protected condition. The configuration of the platen is such that it allows a plurality of photoprint platens to be arranged in a stacked configuration and fed one at the time to a platen imaging station, and then fed from the platen imaging station to a take up location. In a first embodiment the platen has a generally flat mounting surface upon which a photoprint is attachable, and first and second end edges and first and second side edges. One or more regions are located adjacent to the mounting surface area for storing machine readable photoprint parameter information. The platen further includes a plurality of side rail elements extending above the first surface by a height greater than the thickness of a photoprint, so that multiple platens may be stacked together without a photoprint contacting an adjacent platen. In a second embodiment the platen comprises a substrate having a generally flat mounting surface upon which the photoprint is to be placed, the substrate having first and second end edges and first and second side edges. First and second side rail elements adjoin the respective first and second side edges of the substrate and adjoin a transparent cover plate which is arranged to overlie the mounting surface of the substrate and thereby retain a photoprint between itself and the substrate. Ends of the side rail elements have sloped contours to facilitate interleaving of multiple platens together in a stack.

Abstract: The computational effort and time for CELP coding of speech is reduced by rearranging the recursive loop used to search vectors of an adaptive codebook so that an impulse function of a short term perceptually weighted filter is first convolved with perceptually weighted target speech and the result cross-correlated with each codebook vector to produce an error function for identifying the optimum adaptive codebook vector. In addition, autocorrelation is initially performed for only a small number of autocorrelation coefficients in each codebook vector and the values found are used to scan through all the vectors to find those giving a better match to input speech. Autocorrelation using all the vector values is then performed on this subset of vectors to identify the best vector for representing the frame of speech. An end correction procedure is used for vectors shorter than the speech frame length to avoid copy-up errors common in the prior art. An improved means and method for obtaining correlation coefficients for the stochastic codebook vectors is also described..
