  • Publication number: 20220140601
    Abstract: A computer-implemented method includes extending simulation results and input data of a DC production cost model (PCM) of a power grid to an initial AC power flow model (PFM) using a generation distribution mapping and load distribution mapping of a related PFM base example associated with the PCM, and automatically producing a chronological series of converged AC PFM solutions associated with a PCM time series by, for each time step of the PCM time series: (i) updating inputs of an AC PFM using (a) PCM results of the current time step and (b) solution outputs of a converged AC PFM obtained from a previous PCM time step, and (ii) iteratively, reducing nodal loads by a gradual amount configured to account for power grid power flow losses unaccounted for by the PCM and performing AC PFM numerical analyses, until: (a) an AC PFM convergence is obtained and (b) a real power generation slack bus is less than or equal to a predefined tolerance in relation to a slack bus of the PCM results of the current time step.

  • Patent number: 8623441
    Abstract: A brewing system and method are shown for brewing a beverage, such as coffee or tea. The system includes an inline sensor or sensor array that intercepts the dispensing stream and measures the time dependent properties of the brewed liquid at a particular location as the liquid is dispensed. In a particular embodiment, the total dissolved solids is measured to produce a coffee signature, which is sent to a controller that uses the time-dependent data to perform one or more of the following: evaluate the quality of the brewed liquid, control the brewing process for subsequent brewing cycles; identify the blend or brand of brewed product; and/or determine when maintenance is needed or advisable for the brewing system.

  • Patent number: 6526695
    Abstract: A sliding door assembly comprises a frame assembly, a sliding panel carrier, and a sliding panel mounted to the sliding panel carrier. The sliding panel carrier is mounted to the frame assembly for generally rectilinear movement to enable movement of the sliding panel between a closed position and an open position. The sliding panel carrier has a pivot pin receiving opening. A door controlling unit moves the sliding panel carrier in a generally rectilinear manner between the open and closed positions. The sliding panel has a mounting bracket mounted to the top rail thereof. The bracket includes a pivot pin that moves between extended and retracted positions. The sliding panel is mounted to the sliding panel carrier by inserting the pivot pin into the pivot pin receiving opening. As a result, the sliding panel can swing relative to the frame assembly through a breakout movement from a normal, non-breakout position to a breakout position.
