Abstract: A novel asymmetrical cryptographic schema which can be used for enciphering, signature and authentication. The schema is based on low degree public polynomial equations with value in a finite ring K.The mechanism is not necessarily bijective. The secret key makes it possible to hide polynomial equations with value in extensions of the ring K. The solving of these equations makes it possible, if one has the secret key, to execute operations which are not executable with the public key alone.
Abstract: A catheter uses a steerable outer catheter with an inner catheter rotatable and extendable with respect to the outer catheter. The outer catheter may be positioned within a patient's heart and a portion of the outer catheter may provide movement like that of a windshield wiper by manipulation of a spring. By combining the windshield wiper type movement with the extension and rotation of the inner catheter relative to the outer catheter, a large area within a patient's heart may be readily mapped for conduction tissue and be subjected to laser ablation if appropriate. Various configurations provide flexibility in relatively positioning of windows used to apply laser energy and ring electrodes used to sense conduction tissue. Various anchoring techniques are described.

Abstract: The invention relates to a static analyzer of the risks of blocking the operation of a system. The analyzer produces lists of lock applications associated with allocations of the resources of the system which conform to Coffman conditions. The analyzer also produces the names of the source programs from which the lists are extracted. This allows the constructor of the system to modify his source programs in order to eliminate the risks of deadlocking between different processes in the system. The constructor of the system will thus be assured that no allocation of resources will have a blocking effect, no matter what the synchronizations of the various processes being executed in the system may be.

Abstract: An improved thermionic electric converter uses a wire grid cathode to provide a larger surface area for electrons to boil off. Alternately or additionally, the larger electron emission surface area can be achieved by using a curved electron emission surface. A laser provides quantum interference to electrons just before they reach the anode, thereby lowering their energy levels such that they more readily are captured by the anode. The arrangement provides improved conversion efficiency and reduced electron scatter.

Abstract: A process for producing a liquefied natural product such as LNG is described where a single phase nitrogen refrigerant is used in such a way that the refrigerant stream (10) is divided into at least two separate portions (12, 14) which are passed through separate turbo-expanders (106, 108) before being admitted to separate heat exchangers (103, 104) so that the warming curve of the refrigerant more closely matches the cooling curve of the product being liquefied so as to minimize thermodynamic inefficiencies and hence power requirements involved in operation of the method.
Abstract: A system and method for percutaneous myocardial revascularization uses laser energy emitted from the distal end of a catheter. A technique for controlling beam direction allows the creation of channels in a patient's heart tissue with the channels having different orientations relative to the distal end. An arrangement provides for the creation of a plurality of channels at one time by simultaneous application of a plurality of beams of laser energy. A navigation arrangement uses two non-coplanar magnetic sensing coils in the distal end of the catheter cooperating with three sets of three magnetic field generating external coils (i.e., external to the patient). Each of the three sets is sequentially energized and the sensing coils in the distal end sense the magnetic fields established. A computer compares the sensed fields with the known sequence of energizing the external coils and thereby determines the position of the distal end.
Abstract: Signalling device visible throughout 360.degree. comprising a secondary power circuit having, for each diode, a connection area (9), wherein the diodes are located at right angles to said areas. The device is characterized in that the areas (9) for connecting each group of diodes connected electrically in series are, firstly, offset from one another by a reference distance (D), and, secondly, aligned along an axis, known as a series supply line. The device is also characterized in that within a series of series supply lines, the areas (9) for connecting a line are, in relation to the immediately adjacent lines of the same series, offset by a value substantially equal to the ratio of the reference distance divided by the number of lines in the series.
Abstract: A method for filtering a time signal (e(t)) sampled in blocks of N samples (e(n),e(k)) uses a transfer function defined in the frequency domain by LN samples (H(K)). The transfer function is filtered by a time window (g1) of width N, and a frequency subsampling of ratio N is performed to give a partial transfer function defined over N samples (H1(k)). The method enables the complexity of circuits operating in real time to be optimized. The technique is particularly suitable for correcting long echoes in television picture receivers.
