    Abstract: The present invention relates to a station auxiliary power source apparatus that converts power supplied from an overhead cable to generate power to be supplied to a load in a station. The station auxiliary power source apparatus includes a first average calculation unit that calculates the average value of the overhead cable voltage for every predetermined time period; a second average calculation unit that calculates, two or more times, an average value of the overhead cable voltage that is larger than a first average value of the average value among the overhead cable voltages; a third average calculation unit that calculates an average value of the overhead cable voltage per day; and a comparator that selects any one of a second average value of the average value and a third average value of the average value and sets the selected value as the threshold value.

    Abstract: An emergency off-switch for triggering an emergency switch-off function has an actuator and two electrical contact points that can be disconnected from one another by the actuator. The emergency off-switch has an active operating state in which the emergency switch-off function can be triggered by moving the actuator, and a passive operating state in which the emergency off-switch is functionless. The emergency off-switch further has a visualization unit having at least a first and a second display state. The emergency off-switch is visually highlighted in the first display state, and the emergency off-switch is neutrally represented in the second display state. The visualization unit adopts the first display state in the active operating state and adopts the second display state in the passive operating state. The emergency off-switch also has a monitoring unit which monitors whether the visualization unit is in the first or in the second display state.

    Abstract: Systems, methods, and apparatus embodiments for electric power grid and network registration and management of active grid elements. Grid elements are transformed into active grid elements following initial registration of each grid element with the system, preferably through network-based communication between the grid elements and a coordinator, either in coordination with or outside of an IP-based communications network router. A multiplicity of active grid elements function in the grid for supply capacity, supply and/or load curtailment as supply or capacity. Also preferably, messaging is managed through a network by a Coordinator using IP messaging for communication with the grid elements, with the energy management system (EMS), and with the utilities, market participants, and/or grid operators.

    Abstract: A lighting device control system includes a lighting device that includes a communication interface, an optical radiation source, and a fixture controller. The system also may include a gateway controller that is in communication with the lighting device and one or more other lighting devices. The fixture controller or gateway controller identifies that a portable electronic device is in a proximate communication range. The fixture or gateway controller also receives a light operation request from the portable electronic device. The light operation request includes one or more settings for one or more optical characteristics of light that the optical radiation source may emit. The fixture controller determines whether the portable electronic device is authorized to implement the request. In response to determining that the device is authorized, the fixture controller will cause the optical radiation source to emit light that exhibits the optical characteristic(s).

    Abstract: The present disclosure relates to methods and devices for identifying an action. In some embodiments, a method for identifying an action includes: recording vibration trajectory information, wherein the vibration trajectory information corresponds to vibration of at least a portion of an intelligent device from a start of a vibration event to stabilization of the vibration event; determining whether the vibration is a damping vibration based on the vibration trajectory information; and in response to determining that the vibration is a damping vibration, determining that the vibration is caused by a user's trigger action, or in response to determining that the vibration is not a damping vibration, determining that the vibration is not caused by the user's trigger action.
