20140019531 | CONTACT BUILDER - A web-based contact builder, management system and a computer-implemented method to assist a user in efficiently managing and communicating with their designated contacts. The system enables a user to manage existing contacts; to identify via automated means new contacts and determine if they are registered users, or to invite them to join the system; to invite and respond to requests from new contacts in an efficient “one step” method; and to set the level of access that each contact will have to the user's personal identifying information. | 01-16-2014 |

20110175454 | Dual-Loop Dynamic Fast-Tracking MPPT Control Method, Device, and System - A converter unit to improve the response dynamics and overall recovered power in a photovoltaic array configuration. Each photovoltaic panel in the photovoltaic array may be coupled to a respective converter unit, which may include a controller to sense an output voltage and output current produced by the solar panel, and control operation of a power converter to output modified voltage and current corresponding to the solar panel onto a bus coupling the converter units. The controller may operate as an analog or (digital) firmware control system to regulate the input voltage of each power converter unit under indirect guidance of a Maximum Power Point Tracking (MPPT) controller to optimize and regulate the resultant power, and achieve very fast dynamic response to environmental transients. Input voltage and output voltage management may be achieved by way of a fast inner control loop and a corresponding MPPT control system configured as an outer guidance loop providing a reference signal to the inner control loop. | 07-21-2011 |
20110187198 | Constraint Weighted Regulation of DC/DC Converters - A converter unit to improve overall recovered power in a photovoltaic array configuration. Each photovoltaic panel in the photovoltaic array may be coupled to a respective converter unit, which may include a controller to sense an output voltage and output current produced by the solar panel, and manage the output voltage of a corresponding power converter to optimize and regulate the resultant bus voltage to a point which reduces overall system losses, maintains a low loss condition, and removes series-string non-idealities when the panels are series connected. The controller may also adapt to output condition constraints. Instead of single-port regulation, a combination of input voltage and output voltage management and regulation may be performed within the converter. The source voltage and current characteristic may be shaped to correspond to an optimized power curve at the desired bus voltage to allow MPPT tracking according to the DC voltage bus. The optimized power curve may be tracked to hold the DC-bus voltage at the desired operating point. | 08-04-2011 |

20120205974 | Regulation of Inverter DC Input Voltage in Photovoltaic Arrays - A converter unit configured to couple to a photovoltaic panel (PV) may include a controller to sense an output voltage and output current produced by the photovoltaic panel, and manage the output voltage of a corresponding power converter coupled to a DC bus to regulate the resultant bus voltage to a point that reduces overall system losses, and removes non-idealities when the panels are series connected. The controller may also adapt to output condition constraints, and perform a combination of input voltage and output voltage management and regulation, including maximum power point tracking (MPPT) for the PV. The output voltage and output current characteristic of the power converter may be shaped to present a power gradient—which may be hysteretically controlled—to the DC bus to compel an inverter coupled to the DC bus to perform its own MPPT to hold the DC-bus voltage within a determinate desired operating range. | 08-16-2012 |
