The second non-transitory medium includes instructions that when executed by the second controller cause the second controller to receive the target setting, and provide electrical power to the first outlet based on the target setting. | 11-12-2015 |
| 20150338891 | LOCKING POWER SUPPLIES - There is provided an apparatus, a method and computer program product for managing one or more components of an electronic machine. A user connects one or more components to an electronic machine in parallel. The electronic machine determines whether the components are failed. A latch device, attached to each component, automatically locks one or more of the components to the electronic machine if the one or more of the components are not failed. The electromechanical latch automatically releases the one or more of the components from the electronic machine if the one or more of the components are failed. | 11-26-2015 |

| 20160043558 | METHOD AND DEVICE FOR CONTROLLING ELECTRONIC DEVICES - The present invention provides a method and a device for controlling electronic devices. The method includes the following steps. According to a triggering signal, a first control signal is generated for controlling a first electronic device to execute a first action. After that, based on whether the first electronic device executes the first action, a first feedback signal is generated. When the first feedback signal indicates that the first electronic device executes the first action, a second control signal is generated for controlling a second electronic device to execute a second action. Therefore, the method and the device of the present invention provide interaction and simultaneous control between the device and a plurality of electronic devices. | 02-11-2016 |
| 20160056668 | Electrical Control System and Method - A system for controlling an appliance enables electrical circuits to be wired up more quickly, and electrical circuits to be reconfigured more easily. The electrical control system including a central control unit; one or more switch units connected in series forming a loop, the loop including a first end and a second end, wherein the first end and the second end of the loop are connected to the central control unit; and one or more appliance controllers connected to a respective appliance and in communication with the central control unit; wherein one or more electrical parameters are measured at the first end of the loop, and the central control unit sends a control code associated with the one or more electrical parameters to the one or more appliance controllers. | 02-25-2016 |
| 20160105024 | PHASE SELECTION FOR POLYPHASE ELECTRICAL INSTALLATION - A method for balancing a polyphase network for supplying an installation including a plurality of sockets for plugging-in electrical equipment, wherein a phase selector is inserted for each socket, between a system for supplying a polyphase voltage and the socket, and intercepts a command signal for energizing the socket. Once an energizing command has been received from one of the monophase equipments, the least charged phase is selected for powering the equipment, the evaluation of the least charged phase being carried out upstream of the system. | 04-14-2016 |
| 20160111878 | Wall-Mounted Smart Switches and Outlets for Use in Building Wiring for Load Control, Home Automation, and/or Security Purposes - An electrical switch device features a switch module housing that fits at least partially within an in-wall electrical box. The housing contains electrically controlled switches and has line and neutral contacts carried for each of the electrically controlled switches to enable connection of a different respective load circuit across each electrically controlled switch. A control panel is mountable over an open front of the in-wall electrical box and the housing therein, and has a user-interface for operation of the switch module to control the electrically controlled switches and connected loads. The control panel is sized to fully cover the open front of a multi-gang electrical box, whereby the same switch module and control panel are usable with either a single-gang or multi-gang electrical box without leaving any portion of the open front of the single-gang or multi-gang electrical box uncovered by said control panel. | 04-21-2016 |
