Abstract: The present invention is directed to a process for amplifying at least one specific nucleic acid sequence contained in a nucleic acid or a mixture of nucleic acids wherein each nucleic acid consists of two separate complementary strands, of equal or unequal length, which process comprises:
     (a) treating each of the two strands of each different specific nucleic acid sequence being amplified with a primer under conditions such that for each different sequence being amplified an extension product of each primer is synthesized which is complementary to a nucleic acid strand, wherein said primers are selected so as to be substantially complementary to the different strands of each specific sequence such that the extension product synthesized from one primer, when it is separated from its complement, serves as a template for synthesis of an extension product of the other primer;   (b) separating the primer extension product from the templates on which they were synthesized to produce single-stranded molecules; and   (c) treating the single-stranded molecules generated from step (b) with the primers of step (a) under conditions such that a primer extension product is synthesized using each of the single strands produced in step (b) as a template.

Abstract: Both a system and method is provided for detecting faults in the insulating interface (25,30) disposed between the shaft (1) of a generator, and the bearings (23) and seals (11) that rotatably support it that generally comprises a transformer (37) for selectively inducing an alternating electric potential into the shaft while the shaft is stationary, and a voltage meter (38) for detecting whether the transformer-induced voltage is transmitted across the insulating interfaces. The number of wire windings used in the transformer of the system is preferably chosen so that the ac voltage induced in the shaft has substantially the same characteristics as the ac voltage induced by dissymmetry currents when the shaft is rotated by the turbines which drive the electric generator. The system of the invention is capable of not only detecting the existence of an insulation failure, but also its exact location so that only the defective portion of the insulation need be repaired.

Abstract: A diagnostic adaptor module disposed between an appliance and the electrical service having a ferrite toroid sensor which surrounds a wire carrying the main current to the appliance, a sense winding threaded through the toroid, and a microcomputer that monitors the time between corresponding pairs of alternating polarity voltage and current zero crossings, the electrical phase lag of the appliance current, at a rate of two samples per each line cycle whenever at least one major electrical component such as a drive motor or heater is energized. The microcomputer includes software to interpret the phase lag information to determine the operating state of the appliance, and/or detect default conditions as compared to known predefined operation and to support a serial/parallel data interface to the outside world. Depending on the manner in which the adaptor module is being used, serial data may be generated to provide warranty and diagnostic information for appliance maintenance or repair, operational information available to the user, and/or crisis information for a host system capable of deactivating the circuit to which the appliance is connected.

Abstract: A method and apparatus for interfacing a serial data signal (TDATA) having an associated data clock signal (TCLK) to a circuit, which is clocked at a slightly higher local dock frequency, employs a D-type flip-flop (4) to sample the data clock signal at the local clock frequency. Another D-type flip-flop (7) stores the sample previous to that stored by the first flip-flop and on the basis of these two stored samples a decision is made as to which clock pulses (LCLK1; LCLK2) of the local clock should be passed by a gate to form a modified clock signal (LCLK1). This modified clock signal is used to clock a third flip-flop (10; 11) which reads in the bits of the data signal. The modified clock signal can then be used to clock the data through a shift register so that it can be converted to a parallel format.

Abstract: Control of the priority of simultaneous multimedia presentations in a multimedia data processing system is provided. A server accepts and acts on requests for visual and audible precedence over other presentations running on a desktop. The client of the server is given desktop priority by having the associated objects surfaced to the desktop top. This ensures a multimedia application is presented as a foreground process. The server also provides synchronization for multiple clients requesting desktop precedence. The client of the precedence server may be initiated by marks in a presentation which indicate to the client to make a request for precedence. An application may also make a request by virtue of other decisions not initiated by detecting marks in a presentation.
