20140052301 | Method for Globally Optimizing Power Flows in Electric Networks - A power flow problem (OPF) in an electric power network is globally optimized using a branch and bound tree of nodes connected by edges. The BB initially includes at least a root node, and each node represents a feasible region of limits on voltages and powers. An upper bound on the OPF problem is solved for selected nodes using nonlinear programming, while a lower bound is solved using a convex relaxation. The lowest upper and lower bounds are updated using the current upper and lower bound. If a difference between the lowest upper and lowest lower bound is less than a threshold, then outputting the voltages and the powers for the electric power network as represented by the feasibility region for the selected node. Otherwise, the feasible region of the node is partitioned to replace the node. The process is repeated until the tree is empty. | 02-20-2014 |

20150302739 | Remote and Controller Synchronization for Automated Furniture Controls - A system, method, and device for automatic master control detection are provided. In embodiments, automatic master control detection may be utilized to determine a primary control device in a multi-control furniture environment, such as an automated furniture environment. In some aspects, a control device is initially programmed with a particular primary ID. Additionally, such control devices include an alternate ID that may replace the primary ID if it is determined that a conflict exists between the control device and another control device in the same network environment. In one embodiment of the invention, a control device/box/component communicates a startup query upon activation, which automatically signals to other devices in the network that it is the first control started and will retain master control status having the primary ID. Recipient control devices may process a received startup query as an indication to change their primary ID to an alternate ID. | 10-22-2015 |

20140203921 | WIRELESS TWO-WAY COMMUNICATION PROTOCOL FOR AUTOMATED FURNITURE ACCESSORY INTEGRATION - A system and method for integrating furniture accessories and generic devices with automated furniture items is provided. In embodiments, a communication protocol enables a remote device to wirelessly control a generic device wirelessly coupled to a control component of an automated furniture item. The remote device may control features of the generic device based on wireless communication with the control component. In some embodiments, the remote device receives a user environment selection, which is communicated to the control component of the automated furniture item. The automated furniture item then communicates at least a portion of the received command to a corresponding generic device, according to the settings of the selected user environment. In further embodiments, an occupancy detection indication for the automated furniture item may result in a change in one or more settings corresponding to the user environment, as communicated to the generic device(s) by the control component. | 07-24-2014 |
