  • Patent number: 10129549
    Abstract: A higher coding efficiency for coding a significance map indicating positions of significant transform coefficients within a transform coefficient block is achieved by the scan order by which the sequentially extracted syntax elements indicating, for associated positions within the transform coefficient block, as to whether at the respective position a significant or insignificant transform coefficient is situated, are sequentially associated to the positions of the transform coefficient block, among the positions of the transform coefficient block depends on the positions of the significant transform coefficients indicated by previously associated syntax elements. Alternatively, the first-type elements may be context-adaptively entropy decoded using contexts which are individually selected for each of the syntax elements dependent on a number of significant transform coefficients in a neighborhood of the respective syntax element, indicated as being significant by any of the preceding syntax elements.

  • Patent number: 10129973
    Abstract: A voltage divider circuit assembly includes resistors, an external electrostatic shield, and internal electrostatic shield(s). The resistors are in series with each other between input terminals that receive an input voltage. An external resistor is disposed between sensing terminals that conduct an output voltage that is the input voltage divided by the resistors in the series. The external shield is conductively coupled with the series of the resistors with the external resistor disposed outside of the external shield and the other resistor(s) inside the external shield. The internal shield(s) are conductively coupled with the resistors and disposed inside the external shield. A first internal resistor is disposed inside the external shield and outside of the internal shield(s). One or more remaining resistors are inside the internal shield(s). The shields divide parasitic capacitances to enable the measurement of dynamically changing high voltage input signals.

  • Patent number: 10128785
    Abstract: Embodiments of the disclosure relate to transient event mitigating systems and methods that can be incorporated into a power generation system. The power generation system can include an exciter coupled to an alternating current (AC) generator that provides electric power to power lines. The transient event mitigating system can include an automatic voltage regulator that detects a transient event in one or more of the power lines and configures a power converter to respond to the transient event by increasing an amount of direct current (DC) voltage coupled into the power converter. The power converter can provide the increased DC voltage to an exciter coil of the exciter for a transitory period of time in order to adjust the electric power generated by the AC generator and mitigate adverse effects of the transient event.

  • Patent number: 10126164
    Abstract: A flame sensor detects the presence of a flame in a combustion system in which the flame emits light. The flame sensor includes a body connectable with the combustion system. A photodetector is supported in the body. The photodetector responds to light emitted by the flame and generates an electrical signal proportional to an intensity of the light. A window is supported in the body and located between the combustion system and photodetector. The window is susceptible to contamination from the combustion system and the contamination may decrease sensitivity of the photodetector. A light source is supported in the body. The light source emits light so that a predetermined amount of the light emitted by the light source reflects into the photodetector when contamination is present on the window and the photodetector generates a signal indicative of contamination on the window.
