Abstract: An RC oscillator generates a periodic trigger signal, and a clock generator generates clock edges in response. A stuck-at-fault detection circuit detects a stuck-at-logic state of the periodic trigger signal and causes the RC oscillator to reset and causes a change in logic state of the periodic trigger signal. The RC oscillator includes first and second comparison circuits, a logic circuit receiving output from the first and second comparison circuits and generating the periodic trigger signal, and a clock generation circuit generating a clock signal therefrom. The stuck-at-fault detection circuit includes a capacitive node, charge circuitry charging the capacitive node based upon the periodic trigger signal, discharge circuitry discharging the capacitive node based upon the periodic trigger signal, and triggering circuitry asserting a reset signal to cause the RC oscillator to reset when the charge on the capacitive node indicates a stuck-at-logic state of the periodic trigger signal.

Abstract: According to an example, with respect to decentralized supply chain for three-dimensional printing based on distributed ledger technology, three-dimensional printing constraints may be ascertained for a three-dimensional part to be printed, and a plurality of attributes for three-dimensional printers may be ascertained. The three-dimensional printing constraints may be compared to each attribute of the plurality of attributes. A determination may be made as to whether the three-dimensional part is printable by at least one three-dimensional printer or not printable by any three-dimensional printer. Costs associated with three-dimensional printing of the three-dimensional part and non-three-dimensional printing based manufacturing of the three-dimensional part may be ascertained. A determination may be made as to whether the three-dimensional part is to be printed by the at least one three-dimensional printer.

Abstract: The present invention relates to a hydrocracking reactor system and a process utilizing the same for upgrading heavy hydrocarbonaceous material to value-added products. Accordingly, an aspect of the present invention includes dispersing a liquid feedstock pre-mixed with a catalyst from top of a reactor vessel to obtain dispersed droplets having a predetermined droplet size less than 500 ?m, introducing a gaseous feed comprising primarily of hydrogen from bottom of the reactor vessel to form a continuous gaseous phase throughout a cross-section of the reactor vessel, and allowing the dispersed droplets to contact the continuous gaseous phase throughout the cross-section of the reactor vessel to form reaction effluent comprising one or more lighter product hydrocarbons. The method may further include removing at least a top portion and at least a bottom portion of the reaction effluent from the reactor vessel.

Abstract: The present invention discloses a catalyst and process for hydrocracking of heavy hydrocarbon oils having majority portion boiling above 525° C. in the presence of hydrogen. A process comprising first step of converting heavy oil into lighter products in the presence of catalyst and hydrogen in slurry phase is disclosed. The process further comprises recycling of part of liquid products (HVGO) along with fresh heavy oil for improving the product selectivity. This recycled HVGO is having high concentrations of aromatics compounds. The separation of particles generated during the reaction at reactor exit also avoids the chances of choking of downstream sections.

Abstract: A circuit includes an input terminal and a regulated supply line for supplying an electronic device with an electrostatic discharge protection and driver circuit for the electronic device. The supply line is coupled to the input terminal via the circuitry, so that current injected into the input terminal may produce a voltage increase on the regulated supply line. A comparator sensitive to the voltage at the input terminal and the voltage on the supply line is provided. A current sink coupled with the supply line and being activatable to sink current from the supply line is also provided. The comparator is configured for activating the current sink as a result of the voltage at the input terminal exceeding the voltage on the supply line of a certain intervention threshold.

Abstract: Described is a probabilistic concurrency testing mechanism for testing a concurrent software program that provides a probabilistic guarantee of finding any concurrent software bug at or below a bug depth (that corresponds to a complexity level for finding the bug). A scheduler/algorithm inserts priority lowering points into the code and runs the highest priority thread based upon initially randomly distributed priorities. When that thread reaches a priority lowering point, its priority is lowered to a value associated (e.g., by random distribution) with that priority lowering point, whereby a different thread now has the currently highest priority. That thread is run until its priority is similarly lowered, and so on, whereby all schedules needed to find a concurrency bug are run.

Abstract: A digital to analog converter (DAC) that reduces sub-threshold leakage current in PLLs includes three series connected transistors, a unity gain buffer, and a switch. The system is connected between the voltage-to-current converter and a current-controlled oscillator. The DAC receives and accurately mirrors a current signal generated by a voltage-to-current converter.
