Abstract: A system and method for operating a photovoltaic element at or near a maximum power point. A maximum power point tracker changes a voltage or current set point of a photovoltaic element in sequential discrete steps, measuring an output power at each step after a predetermined settling time. A slope of a power-voltage curve is then estimated and the slope is corrected for irradiance changes. Finally, an operating voltage or current of the photovoltaic element is adjusted based on the slope of the power-voltage curve and other factors, causing the photovoltaic element to operate at or near its maximum power.

Abstract: The present invention employs branded virtual characters across multiple network platforms throughout various stages of complex transactions (eg, selling insurance). These characters initially engage prospective customers on a network platform, such as a social network, and persist over time across other network platforms (eg, university and company websites) to educate consumers until they are ready to purchase—e.g., from their “trusted advisor”—particular products and services offered by various providers. An extensible configuration tool (“Config Tool”) is provided to simplify the continued development of such a system, as well as customization of individual Product Modules (e.g., a Life Insurance Module) by product and service providers (e.g., insurance companies and employers) and other third-party developers (before and during runtime).

Abstract: Aspects of the invention provide systems and methods for facilitating a recurring series of distinct drawings (e.g., lottery, sweepstakes, raffles, etc.), for a prize or a variety of prizes (e.g., from one source or a variety of sources), over an extended period of time, or for an open-ended period of time. In addition, a user can enter the recurring series of drawings through a single registration (e.g., entry into a drawing database). The entrant will be continuously entered into the series of recurring drawings until the entrant is removed from the database, e.g., opts out of the system. In one embodiment, preferences and attributes can be determined for each entrant and these preferences and attributes can be used to enter the entrant into a customized series of recurring drawings.

Abstract: In certain embodiments, a system includes a first milking box stall of a size sufficient to accommodate a dairy livestock. The system also includes an equipment portion located adjacent to the first milking box stall. The equipment portion houses a robotic attacher. The system also includes a second milking box stall of a size sufficient to accommodate a dairy livestock. The second milking box stall is located adjacent to the equipment portion. The robotic attacher is configured to service both the first milking box stall and the second milking box stall by extending between the rear legs of a dairy livestock located within either stall in order to attach milking equipment to the dairy livestock.

Abstract: A metrological instrument determines a surface profile or form of a surface (61) of a workpiece (60) by effecting relative movement between a probe (11, 12) and the surface (61) so that the probe follows and is displaced by changes in the surface topography. A measure of the displacement of the probe as it follows the surface is obtained by a displacement provider which may be an interferometric gauge (35). Instead of making a measurement along a single measurement path over the surface (61), respective measurements are made on sections (61d and 61e or 61g and 61h) of that measurement path to obtain corresponding measurement data sets and these measurement data sets are independently positioned or aligned to a reference data set. The reference data set may be obtained by a measurement made on another section (61c) of the measurement path (61), on another measurement path (61f) over another surface (62a and 62b) of the component or on another measurement path over a surface on which the component is located.

Abstract: An electrical power generation system, such as a solar power inverter, can provide dynamic real-time power compensation, so as to mitigate the effects of voltage sags and swells (e.g., on a utility grid) and thereby provide voltage support functionality to a local grid. The electrical power generation system can do so by receiving first synchrophasor measurements that are taken at a point on the utility grid and transmitted to the electrical power generation system and by taking second synchrophasor measurements. The first and second synchrophasors indicate voltage magnitude and frequency of the alternating current (AC) at their respective measurement points. The electrical power generation system can compare the first synchrophasors with the second synchrophasors and based upon the comparison, vary the power factor of the power the electrical power generation system generates (e.g., by either supplying or absorbing reactive power).

Abstract: Systems and methods of synchronizing media are provided. A client device may be used to capture a sample of a media stream being rendered by a media rendering source. The client device sends the sample to a position identification module to determine a time offset indicating a position in the media stream corresponding to the sampling time of the sample, and optionally a timescale ratio indicating a speed at which the media stream is being rendered by the media rendering source based on a reference speed of the media stream. The client device calculates a real-time offset using a present time, a timestamp of the media sample, the time offset, and optionally the timescale ratio. The client device then renders a second media stream at a position corresponding to the real-time offset to be in synchrony to the media stream being rendered by the media rendering source.
