  • Patent number: 10913902
    Abstract: Methods to convert an oxygen containing organic compound(s) to one or more water-free liquid hydrocarbons products. They make use of a catalytic process in a two-stage reactor system having a first reactor and a second reactor in series. Process design is described for effective conversion of aqueous low energy-dense aqueous solutions containing oxygen containing organic compound(s) to liquid hydrocarbons; the process design preferably employs the solid acid catalysts comprised of microporous aluminosilicates denoted as zeolites mixed with silicon carbide binder in series of two reactor system with capability of complete water removal.

  • Patent number: 9222971
    Abstract: System circuitry includes a logic circuit having an input and an output that is a functional element of the system circuitry. Pattern application circuitry is coupled to the input of the logic circuit and provides an input pattern to the input of the logic circuit. The input pattern has a valid signature based upon a comparison of the input and the output of the logic circuit when the logic circuit is functioning properly. A logic comparator is coupled to the input and the output of the logic circuit and generates pulses in response to the input pattern. A counter is coupled to the logic comparator that obtains a count of the pulses generated by the logic comparator in response to the input pattern. A signature comparator is coupled to the counter and generates a warning signal if the valid signature is different from the count.

  • Patent number: 9043620
    Abstract: A data processing system on an integrated circuit includes a core that performs switching operations responsive to a system clock that draws current from the power supply network. An IR-drop detector includes a resistor ladder having outputs representative of an IR-drop caused by the core during the switching operations. The system further includes a plurality of amplifiers coupled to the outputs indicative of the IR-drop, a plurality of flip-flops coupled to the amplifiers, and a variable clock generator. The variable clock generator outputs a sampling clock comprising a group consisting of a variable phase or a variable frequency to the plurality of flip-flops. The flip-flops are triggered by the sampling clock so that the IR-drop at a time during a clock cycle of the system clock can be detected, and the peak IR-drop value for can be tracked.
