    Abstract: A load control device may be configured to control an electrical load, such as a lighting load. The load control device may include a first terminal adapted to be coupled to an alternating-current (AC) power source, and a second terminal adapted to be coupled to the electrical load. The load control device may include a bidirectional semiconductor switch, a filter circuit, and a control circuit. The bidirectional semiconductor switch may be coupled in series between the first terminal and the second terminal, and be configured to provide a phase-control voltage to the electrical load. The filter circuit may be coupled between the first terminal and the second terminal. The control circuit may be configured to render the bidirectional semiconductor switch conductive and non-conductive to control an amount of power delivered to the electrical load, and be configured to adjust the impedance and/or filtering characteristics of the filter circuit.

    Abstract: Systems and methods are disclosed for using one or more gateway systems for integrating multiple load control systems running multiple versions of software such that the load control systems may appear to a user and be controlled by the user as a unified load control system. Gateways that manage or have managed the same resource may be organized into a Gateway Group. Gateway Groups names may be used for prefix attachment to facilitate routing. For example, a Composite Gateway may receive a request associated with a resource from a user. The Composite Gateway may determine which Gateway actively manages that resource and/or is the Gateway is a member of a Gateway Group. The composite Gateway may then apply one or more policies to facilitate the request. For example, if the Composite Gateway receives an information request, it may apply an authorization policy, a routing policy, and/or an aggregation policy.

    Abstract: A first wireless control device may be associated with a second wireless control device in response to the movement of the first wireless control device in relation to the second wireless control device. The second control device may determine whether the signal strength of the wireless signals received from the first wireless control device has changed, and may associate the first wireless control device with the second wireless control device if the signal strength of the received wireless signals has changed. The second control device may be disassociated with the first control device by moving the first wireless control device in relation to the second wireless control device. The second control device may disassociate the first control device when the signal strength of subsequent wireless signals received from the first wireless control device has changed.

    Abstract: A controller comprises a controllably conductive device adapted to be coupled in series electrical connection between an AC power source and a load control device. The controller also comprises a control circuit coupled to the controllably conductive device for rendering the controllably conductive device conductive each half-cycle of the AC power source to generate a phase-control voltage. The control circuit is operable to render the controllably conductive device conductive for a portion of each half-cycle of the AC power source. The control circuit is operable to transmit a digital message to the load control device for controlling the power delivered to the load by encoding digital information in timing edges of the phase-control voltage, where the phase-control voltage having at least one timing edge in each half-cycle of the AC power source when the control circuit is transmitting the digital message to the load control device.

    Abstract: A load control device for controlling the amount of power delivered to an electrical load may include a rectifier circuit configured to receive a phase-control voltage and produce a rectified voltage. A power converter may be configured to receive the rectified voltage at an input and generate a bus voltage. An input capacitor may be coupled across the input of the power converter. The input capacitor may be adapted to charge when the magnitude of the phase control voltage is approximately zero volts. The power converter may be configured to operate in a boost mode, such that the magnitude of the bus voltage is greater than a peak magnitude of the input voltage. The power converter may be configured to operate in a buck mode to charge the input capacitor from the bus voltage when the magnitude of the phase-control voltage is approximately zero volts.

    Abstract: A load control system has a system controller and a plurality of load control devices which receive power from a utility power source. The load control system has at least one emergency load control device which receives power from a backup power source in the event of a power failure of the utility power source. The emergency load control device is configured to enter an emergency mode during the power failure of the utility power source, wherein in the emergency mode, the emergency load control device controls respective electrical loads according to emergency mode preset settings, and the emergency load control device transmits a message to the system controller to indicate the emergency load control device is in the emergency mode. The system controller is configured to transmit a message to the emergency load control device to exit the emergency mode when power from the utility power source is restored.

    Abstract: A load control device for controlling the power delivered from an AC power source to an electrical load is able to receive radio-frequency (RF) signals from a Wi-Fi-enabled device, such as a smart phone, via a wireless local area network. The load control device comprises a controllably conductive device adapted to be coupled in series between the source and the load, a controller for rendering the controllably conductive device conductive and non-conductive, and a Wi-Fi module operable to receive the RF signals directly from the wireless network. The controller controls the controllably conductive device to adjust the power delivered to the load in response to the wireless signals received from the wireless network. The load control device may further comprise an optical module operable to receive an optical signal, such that the controller may obtain an IP address from the received optical signal and control the power delivered to the load in response to a wireless signal received from the wireless network that includes the IP address.
