The utility meter stores a firmware update downloaded from the utility service provider, and determines a particular time to update the firmware with the firmware update, in which the particular time is determined based at least in part on historical time of use data, time of use pricing rates, or a combination thereof. The historical time of use data include utility consumption by a consumer over time and the time of use pricing rates include the price per unit of utility charged to the consumer. Additionally, the utility meter updates the firmware at the particular time.

  • Patent number: 9893563
    Abstract: The present subject matter is directed to a wind turbine electrical power configured to minimize power losses. The power system includes a generator having a generator stator and a generator rotor, a power converter electrically coupled to the generator, a main transformer electrically coupled to the power converter and the power grid, and an auxiliary transformer. More specifically, the main transformer is connected to the power grid via a voltage line comprising a voltage switch gear. Thus, the auxiliary transformer is connected directly to the voltage line, i.e. rather than being connected to the grid through the main transformer.

  • Patent number: 9894747
    Abstract: Radio-frequency (RF) electrode for a cyclotron. The RF electrode includes a hollowed dee having first and second surfaces that oppose each other and define a gap therebetween. The hollowed dee is configured to be electrically controlled to direct a beam of charged particles through the gap and along an orbit plane of the cyclotron. The orbit plane extends parallel to the first and second surfaces through the gap. The RF electrode also includes a bridge structure that is coupled to and extends away from the hollowed dee. The bridge structure includes a side wall that defines an interior cavity of the bridge structure. The side wall has a particle opening therethrough that coincides with or is proximate to the orbit plane such that the particle opening receives neutral particles from an orbit of the charged particles.

  • Patent number: 9894368
    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.
