Patent EP-0008033-A1 (EP)
Inventor: BEST ROBERT MACANDREW
IPC: G11B15/02
Filed: 1979-07-23
Abstract: A microprocessor (16) for executing computer programs (12) which are stored (12) in cipher to prevent software piracy. Such a crypto-microprocessor (16) deciphers (4) the enciphered program (12) piecemeal as it executes it (67), so that a large enciphered program (12) can be securely executed without disclosing the deciphered program or associated data to persons who have access to the wiring of the computer in which the crypto-microprocessor (16) is a component. Various methods of deciphering may be used including methods which result in the cipher of a byte being a complex function of the byte's address in memory. Each crypto-microprocessor chip (16) may use a unique cipher key (5) or tables for deciphering the program (12), so that a program that can be executed in one chip cannot be run in any other microprocessor.

Abstract: A miniaturized electric coil having a centre tap (10) which is constructed from a spiral-like bottom conductor pattern (1) provided on a substrate, an insulating intermediate layer (11) and a spiral-like top conductor pattern (16) which is connected to the bottom conductor pattern via windows (12, 13, 14, 15 and soon) in the intermediate layer. A conductor path (23) which is situated in the top conductor pattern is led out from the interior of the top conductor pattern to form the tap (10). At the area of said conductor path the conductors of the top conductor pattern are locally interrupted, in which connection conductors in the bottom conductor pattern are connected parallel to the interruptions so as to ensure an undisturbed current flow in the top conductor pattern.

Abstract: A radar system which utilizes the combined techniques of interferometric clutter discrimination and synthetic aperture imaging is disclosed as is the method for effecting clutter notching using the combined techniques. Two antennas (12,14), spaced apart by a predetermined number of wavelengths, receive return signals which are processed into a fine grid of range and doppler cells, including the relative phase difference of each which is a measure of the angle (e, ⊖) of arrival of the respective signals, to form an uncompensated complex image plane (24, 30) of the target area scene by each of the antennas. The clutter signals of only one image plane are then phase shifted by the measure of their angle of arrival and subsequently summed, cell-by-cell, with the signals of the other image plane to form a clutter-free moving-target image plane.

Abstract: Dispositif pour amortir des ondes sonores a basse frequence, telles que des infrasons dans des pompes ou des ventilateurs centrifuges. Le dispositif est compose d'un ou de plusieurs canaux interposes entre les ondes sonores (5, 10, 11) qui relient le bati (1) les ventilateurs, etc., et le canal (3) ou les canaux conventionnels de debit. L'amortissement des ondes sonores du ventilateur, etc., s'accomplit par interference aux endroits de couplages entre les ondes sonores dans les canaux de debit (3) et les canaux de transmission des ondes sonores (5, 10, 11). Grace aux canaux supplementaires (5, 10, 11) qui ne sont que des transmetteurs d'ondes sonores, on supprime les perturbations de debit et les instabilites dues a l'efficacite diminuee ainsi que l'augmentation du bruit. Les canaux supplementaires (5, 10, 11) peuvent etre des canaux de debit de type conventionnel, mais avec une ou plusieurs membranes (6, 7) ou autre organe de transmission d'ondes sonores montes dans les ouvertures des canaux supplementaires (5, 10, 11) afin d'etre ajuste aux formes de circulation conventionnelles.
