Abstract: A load control system may control an electrical load in a space of a building occupied by an occupant. The load control system may include a controller configured to determine the location of the occupant, and a load control device configured to automatically control the electrical load in response to the location of the occupant. The load control system may also include a mobile device adapted to be located on or immediately adjacent the occupant and configured to transmit and receive wireless signals. The load control device may be configured to automatically control the electrical load when the mobile device is located in the space. The load control system may further comprise an occupancy sensor and the load control device may automatically control the electrical load when the occupancy sensor indicates that the space is occupied and the mobile device is located in the space.

Abstract: A remote control device may be configured to be mounted over the toggle actuator of a light switch and to control a load control device via wireless communication. The remote control device may include a base portion and a rotating portion supported by the base portion so as to be rotatable about the base portion. The remote control device may include a control circuit and a wireless communication circuit. The control circuit may be operably coupled to the rotating portion and to the wireless communication circuit. The control circuit may be configured to translate a force applied to the rotating portion of the remote control device into a control signal and to cause the communication circuit to transmit the control signal to the load control device.

Abstract: A load control system may control an electrical load in a space of a building based on one or more parameters regarding the physical condition of an occupant. The parameters may be gathered by one or more sensing devices. The sensing devices may be included in a mobile device. A system controller may receive the parameters and may automatically control the electrical loads in response to the parameters. The system controller may control the electrical load to attempt to adjust the physical condition of the occupant in response to the sensed parameters. The system controller may control the electrical load to provide an alert, an alarm, and/or a warning in response to the sensed parameters.

Abstract: A load control device may include a semiconductor switch, a control circuit, and first and second terminals adapted to be coupled to a remote device. The load control device may include a first switching circuit coupled to the second terminal, and a second switching circuit coupled between the first terminal and the second terminal. The control circuit may be configured to render the first switching circuit conductive to conduct a charging current from an AC power source to a power supply of the remote device during a first time period of a half-cycle of the AC power source, and further configured to render the first and second switching circuits conductive and non-conductive to communicate with the remote device via the second terminal during a second time period of the half-cycle of the AC power source.

Abstract: A control module is able to be installed with electrical devices, such as, for example electrical loads (e.g., lighting loads) and/or load regulation devices. The control module may determine whether an LED driver for an LED light source is responsive to one or more of a plurality of control techniques. The control module may be able to automatically determine an appropriate control technique to use to control the connected LED driver and/or LED light source. The control module may sequentially attempt to control the LED driver and/or LED light source using each of the plurality of control techniques and determine if the LED driver and/or LED light source is responsive to the present control technique. The plurality of control techniques may include one or more analog control techniques and one or more digital control techniques.

Abstract: An energy savings selector tool may assist a user in determining electrical devices that, when implemented in a load control system, may reduce an amount of power used by the load control system. The energy savings selector tool may use load control information of the load control system to identify electrical devices that may be added to or replace other electrical devices in the load control system. The load control information may define operations of the load control system and/or include energy usage information of the load control system. The energy savings selector tool may identify savings information associated with implementing an electrical device in the load control system. Once an electrical device is installed in the load control system, the energy savings selector tool may be used to report energy savings information about the electrical device.

Abstract: A multiple location load control system comprises a main device and remote devices, which do not require neutral connections, but allow for visual and audible feedback at the main device and the remote devices. The main device and the remote devices are adapted to be coupled together via an accessory wiring. The main device can be wired on the line side and the load side of the load control system. The main device is configured to enable a charging path to allow the remote devices to charge power supplies through the accessory wiring during a first time period of a half cycle of the AC power source. The main device and the remote devices are configured to communicate with each other via the accessory wiring during a second time period of the half cycle, for example, by actively pulling-up and actively pulling-down the accessory wiring to communicate using tri-state logic.
