20090206769 | Smart Load Control Device Having a Rotary Actuator - A load control device for controlling the amount of power delivered from an AC power source to an electrical load comprises a rotary actuator, such as a rotary knob or a rotary wheel. The load control device increases and decreases the amount of power delivered to the electrical load in response to rotations of the rotary knob in first and second directions, respectively. The load control device accelerates the rate of change of the amount of power delivered to the load in response to the angular velocity of the rotary actuator. The load control device generates a ratcheting sound when the rotary actuator is rotated in the first direction at a high-end intensity of the load control device. The load control device is operable to control the electrical load in response to both actuations of the rotary actuator and digital messages received via a communication link. | 08-20-2009 |
20090206983 | Communication System for a Radio-Frequency Load Control System - A radio-frequency (RF) load control system allows for the expedient transmission of subsequent digital messages to one or more recipients via an RF communication link. The control system comprises at least one load control device for controlling the amount of power delivered to an electrical load in response to a received digital message. Each control device of the load control system is operable to interrupt the propagation of a first digital message to transmit a second digital message in response to determining that the second digital message has a high priority than the first digital message. For example, an originating control device may transmit first and second digital messages in response to a press and a release of an actuator, respectively, and may interrupt the propagation of the first digital message to transmit the second digital message if the first digital message is irrelevant in view of the second digital message. | 08-20-2009 |

20120056712 | METHOD OF CONFIGURING A TWO-WAY WIRELESS LOAD CONTROL SYSTEM HAVING ONE-WAY WIRELESS REMOTE CONTROL DEVICES - A radio-frequency (RF) load control system includes both two-way and one-way (e.g., transmit-only) remote control devices, and provides a simple, reliable process for configuring the one-way devices into the system. The one-way device may be programmed to operate at one of a predetermined number of radio frequencies as part of a frequency-selection procedure, during which, the one-way device transmits a test command to a signal repeater of the system. If the test command is transmitted at the same frequency as the repeater, the repeater emits an audible beep to inform the user that the remote control is transmitting at the appropriate frequency. To associate the two-way devices with the system, the signal repeater streams an “enter address mode” command. To allow the one-way device to be associated with the system, the signal repeater pauses the transmission of the enter address mode command to allow the one-way device to transmit an activation request message to the signal repeater. | 03-08-2012 |

20130026947 | Method Of Programming A Load Control Device Using A Smart Phone - A load control device 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 an AC power source and an electrical load, a controller for rendering the controllably conductive device conductive and non-conductive, and a Wi-Fi module operable to receive the RF signals 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 that includes the IP address. | 01-31-2013 |

20140265881 | STATE CHANGE DEVICES FOR SWITCHED ELECTRICAL RECEPTACLES - A state change device may be electrically connected to a switched receptacle, or to both the switched and unswitched receptacles, of an outlet. The state change device may generate a change of state signal when power is applied to, or removed from, the switched receptacle. The state change device may wirelessly communicate the signal. The state change device may include a load control circuit that may be configured to control the amount of power delivered to an electrical load that is electrically connected to the state change device. The state change device may receive commands directed to the load control circuit. The state change device may be deployed in a load control system and may operate as a control entity, such that the state change device may issue commands to one or more load control devices, responsive to the application or removal of power at the switched receptacle. | 09-18-2014 |
