Abstract: A method for controlling the execution of a sole target processor or a target processor embedded in a chain of target processor units by a host-processor. The target processor unit includes a shared control register, a shared memory accessible by both the target and host processor and a code memory alterable by the host processor and containing the target processor program. The shared control register includes a single step flag to indicate that the host processor is setting the single step mode of operation for the target processor. The shared control register further includes a clock inhibit flag to permit the target processor to stop execution. Clearing the clock inhibit flag releases the target processor to execute the program in the code memory during which the target processor tests the single step flag to determine whether it should stop execution after one instruction has been executed.

Abstract: A sputtering apparatus and method for high rate deposition of electrically insulating and semiconducting coatings with substantially uniform stoichiometry. Vertically mounted, dual rotatable cylindrical magnetrons with associated vacuum pumps form semi-isolated sputtering modules, which can be independently controlled for the sequential deposition of layers of similar or different materials. Constant voltage operation of AC power with an optional reactive gas flow feedback loop maintains constant coating stoichiometry during small changes in pumping speed caused by substrate motion. The coating method is extremely stable over long periods (days) of operation, with the film stoichiometry being selectable by the voltage control point. The apparatus may take the form of a circular arrangement of modules for batch coating of wafer-like substrates, or the modules may be arranged linearly for the coating of large planar substrates.

Abstract: The present invention is related to a bipolar transistor in which the in-situ doped epitaxial Si or SiGe base layer is used instead of using an ion-implanted Si base, in order to achieve higher cutoff frequency. The SiGe base having the narrower energy bandgap than the Si emitter allows to enhance the current gain, the cutoff frequency (fT), and the maximum oscillation frequency (fmax). The narrow bandgap SiGe base also allows to have higher base doping concentration. As a result, the intrinsic base resistance is lowered and the noise figure is thus lowered. Parasitic base resistance is also minimized by using a metallic silicide base ohmic electrode. The present invention is focused on low cost, high repeatability and reliability by simplifying the manufacturing process step.

Abstract: An apparatus and associated method for detecting impending earthquakes includes at least one sensor, and preferably multiple sensors, for mounting on a building or other like structure, and include a transducer for converting vibration signals to electronic impulses. The signals are transmitted to a solid state detection circuit, which distinguishes between extraneous signals and signals indicative of the P-waves which signal an impending earthquake. Discrimination between relevant and non-relevant may be achieved by selecting a minimum amplitude and duration of signals within a selected frequency range, and triggering an alarm when the selected minimums are exceeded. Where multiple sensors are deployed, temporal overlap between selected signals can be assessed for further discrimination.

The host terminal will continuously monitor the terminals of all play participants, dynamically record play status, and control termination of the game period. It will also conduct an accounting of the results, issue win results notification, and perhaps provide remote pay-out of game winnings.
