  • Patent number: 10579126
    Abstract: An electronic device (20) has a clock path (24) for propagating a clock signal and a clock propagating element (26) on the clock path. An analogue element (30) coupled to the clock path (24) varies, in dependence on an analogue level of a first signal (32), a switching delay for the clock propagating element (26) to trigger a transition of the clock signal. The first signal is a digitally sampled signal. This provides a mechanism for providing a fast reduction in clock frequency even if the first signal is a metastable signal, which is useful for avoiding errors causes by voltage drops.

  • Patent number: 10578307
    Abstract: A gas turbine assembly and method for operating the gas turbine assembly are provided. The method for operating the gas turbine assembly may include compressing a process fluid containing inlet air through a compressor to produce compressed inlet air, combining fuel from a main fuel source with the process fluid, and preheating the process fluid containing the inlet air and the fuel in a warmer disposed downstream from the compressor. The method may also include heating an oxidizer by flowing the preheated process fluid from the warmer to the oxidizer, and oxidizing the process fluid containing the compressed inlet air and the fuel in the oxidizer to produce an oxidation product. The method may further include expanding the oxidation product in a turbine to generate rotational energy, and preventing the process fluid from flowing upstream to the compressor with a check valve.

  • Patent number: 10581485
    Abstract: The present disclosure relates to near-end crosstalk (NEXT) cancellation. A transmit communication signal is transmitted over a first Digital Subscriber Line (DSL) connection using a first group of frequencies and a receive communication signal is received over a second DSL connection using a second group of frequencies that at least partially overlaps the first group of frequencies. A crosstalk correlation between the first and second communication signals is determined. Based on the crosstalk correlation, a crosstalk cancellation signal is generated. The crosstalk cancellation signal is subtracted from the second communication signal, with the intention of reducing NEXT.

  • Patent number: 10579515
    Abstract: Techniques for recycling segment pages while preserving integrity of memory addressing. Upon a request to delete a system object, an initial segment identifier is de-assigned from a segment of the system object, and each segment page of the system object is remapped to a new virtual address range. The segment is stored as a reusable segment in a reusable segment store. Upon a request to access the system object, an exception is raised that the system object does not exist. Upon a request to create a new system object, the reusable segment store is searched to identify the reusable segment as a match. The reusable segment is assigned as a segment of the new system object.

  • Patent number: 10581908
    Abstract: Embodiments of the present invention are directed to identifying phishing websites by rendering and analyzing document object model (DOM) objects associated with a website for features that indicate phishing behavior. Embodiments analyze the full scope and functionality associated with a website by executing functions embedded in a DOM object before analyzing the website for phishing activity. Accordingly, embodiments render and analyze a fully executed DOM object for phishing behavior. Embodiments may then perform steps to mediate a website that is classified as performing phishing. Thus, embodiments are configured to (1) collect website information from a variety of websites and web servers connected to the internet, (2) analyze the collected data to determine whether the website information is performing phishing, and (3) mediate websites and other actors that are determined to be performing phishing based on the results of the phishing analysis.

  • Patent number: 10579134
    Abstract: Systems and methods for displaying an image of a virtual object in an environment are described. A computing device is used to capture an image of a real environment including a marker. One or more virtual objects which do not exist in the real environment are displayed in the image based at least on the marker. The distance and orientation of the marker may be taken into account to properly size and place the virtual object in the image. Further, virtual lighting may be added to an image to indicate to a user how the virtual object would appear with the virtual lighting.

  • Patent number: 10581052
    Abstract: A separator for a bobbin-style electrochemical cell is inserted into an interior opening within a ring-shaped cathode in an electrochemical cell can. An expansion force is then applied to an interior surface of the separator to press the separator against the interior walls of the cathode. A tool may then remove various creases and/or wrinkles in the separator and/or may then heat seal at least a portion of the tubular walls of the separator to minimize the void space between the separator and active material (e.g., cathode and/or anode) within the electrochemical cell.
