Systems, methods and apparatus for electric power grid management and communications are disclosed. At least one active grid element is constructed and configured in network-based communication with a server via at least one coordinator. The at least one active grid element communicates Internet Protocol (IP)-based messages with the server via the at least one coordinator in real time or less than 15 minutes interval. The at least one active grid element participates actively in an electric power grid. The at least one active grid element has an energy consumption pattern or an energy supply pattern. The IP-based messages comprise at least one IP packet including a content, a priority, a security, and a transport route. The content comprises an amount of power available for the electric power grid or an amount of curtailment power available at an attachment point of the at least one grid element.

A building control system for configuring and deploying electronic devices installed in a building comprising a plurality of space control systems. Each space control system comprises a plurality of electronic devices adapted to communicate via a network to control at least one load installed in the space and a memory that stores device data comprising a unique identifier that uniquely identifies the electronic device within the building control system associated with a device identifier that references the electronic device within the space control system. The electronic devices of one space control system can be configured by assigning at least one setting to at least one device identifier. A template can be created comprising the device identifiers and associated settings of the one of the space control systems. The template can be applied another space control system by applying the settings in the template to electronic devices with matched device identifiers.

A system for inspecting each workpiece of a plurality of non-identical workpieces, each workpiece having a distinct workholding specification. The system includes a workholder configured to autonomously execute a plurality of workholding operations pursuant to parameters of a specified pre-defined workholding mode specified from a plurality of distinct, pre-defined workholding modes. Each pre-defined workholding mode specifies a plurality of holding parameters corresponding to the holding specification of a corresponding workpiece.

Disclosed are a doorbell system and a method for controlling a doorbell system that includes a shunt unit electrically connected to a signaling unit of a doorbell system, a power harvest unit electrically connected to the shunt unit and the signaling unit, a first switch unit, the power harvest unit being selectively connected to an external power source via the first switch unit, a button unit that receives a press operation, and a detection and control unit that detects whether there is a press operation, and controls the first switch unit to be in a first mode when no press operation is detected, the power harvest unit harvests power from the external power source via the first switch unit in the first mode, and controls the first switch unit to be in a second mode and controls the signaling unit to make sound when the press operation is detected.

An audio/video (A/V) recording and communication doorbell device includes a transistor assembly and control circuitry. The transistor assembly is electrically coupled between an input power bus that distributes alternating current (AC) input power and/or direct current (DC) input power, and an output power bus that provides a DC output power for the A/V recording and communication doorbell device. The control circuitry is configured to cause the transistor assembly to convert AC input power and/or DC input power from the input power bus to the DC output power into the output power bus, to provide the DC output power for the A/V recording and communication doorbell device.
