20100333125 | Subscriber Characterization System with Filters - A subscriber characterization system with filters in which the subscriber's selections are monitored, including monitoring of the time duration programming is watched, the volume at which the programming is listened to, and any available information regarding the type of programming, including category and sub-category of the programming. The raw subscriber selection data is then processed to eliminate data associated with irrelevant activities such as channel surfing, channel jumping, or extended periods of inactivity. The actual subscriber selection data is used to form program characteristics vectors. The programming characteristics vectors can be used in combination with the actual subscriber selection data to form a subscriber profile. Heuristic rules indicating the relationships between programming choices and demographics can be applied to generate additional probabilistic subscriber profiles regarding demographics and programming and product interest. | 12-30-2010 |
20120102512 | Grouping Advertisement Subavails - Method and system for creating one or more advertising avail sections (subavails) and thereupon aggregating the subavails to form one or more groups of subavails. The advertisement opportunities (avails) may be divided into sections (subavails) with each section being directed at a particular target audience (group). The subavails are then aggregated into one or more groups of subavails so that the groups of subavails can be sold to the advertisers.

20150186353 | VISUAL CUE LOCATION INDEX SYSTEM FOR E-BOOKS AND OTHER READING MATERIALS - Visual indicators are added to each page or screen of an e-book display to provide a visual cue to help the user associate the visual cue with content of the book and go back to previously read contents using the visual cue. The visual indicators are icon-like graphic objects placed at a desired location on the page. They have shapes that are simple, easy to remember, and easily distinguished from each other. In one example, each visual indicator has an outline shape such as a circle, triangle, square, etc. which starts out empty with no fill. As the user moves forward in the book the current visual indicator is progressively filled with a pattern. Once the visual indicator is fully filled the next visual indicator is selected and the process repeats. The visual indicators are automatically generated for each page based on the position of the page within the e-book. | 07-02-2015 |

20110226559 | BATTERY STATE-OF-CHARGE CALIBRATION - Calibration of the state-of-charge (SOC) of a battery-based energy storage system used with a regenerative drive uses an SOC-open circuit voltage (V?oc#191) correlation. The battery is partially charged or discharged to assure operation defined by V?oc#191 following a known V?oc#191-SOC profile, such as a charge or discharge boundary curve. The partial charging/discharging may be synchronized with a traffic profile of an elevator system driven by the regenerative drive. A V?oc#191 measurement is made, and by enhancing the relaxation dynamics of V?oc#191 through regulating battery usage with a reference to traffic profile, a V?oc#191 is estimated more reliably. Using the estimate V?oc#191 and the known V?oc#191-SOC profile, state-of-charge of the battery is determined. | 09-22-2011 |

20140376283 | SYSTEMS AND METHODS FOR ACTIVE DAMPING DEVICE FOR STABILIZING A POWER GRID OF ACTIVE SOURCES AND LOADS - Embodiments relate to systems and methods for an active damping device for stabilizing a power grid of active sources and loads. In power system networks or grids which incorporate active power sources and active loads, such as motors, the output voltage transfer function can exhibit instabilities due to the presence of poles in the positive real portion (right hand side) of the complex plane. Those poles can induce uncontrolled ringing, oscillations, or other artifacts or instabilities. According to implementations, an active damping element can be introduced into the power system grid, which operates to drive the poles of the output transfer function to the negative real (left hand) portion of the complex plane. Output voltage and other parameters can thereby be stabilized. In implementations, the damping element can include an R-C network for DC output systems, or a controller including a voltage source inverter for AC output systems. | 12-25-2014 |
