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.

Load Control Device Having Internet Connectivity

A high speed serial interface is provided. In one aspect, the high speed serial interface uses three phase modulation for jointly encoding data and clock information. Accordingly, the need for de-skewing circuitry at the receiving end of the interface is eliminated, resulting in reduced link start-up time and improved link efficiency and power consumption. In one embodiment, the high speed serial interface uses fewer signal conductors than conventional systems having separate conductors for data and clock information. In another embodiment, the serial interface allows for data to be transmitted at any speed without the receiving end having prior knowledge of the transmission data rate. In another aspect, the high speed serial interface uses polarity encoded three phase modulation for jointly encoding data and clock information. This further increases the link capacity of the serial interface by allowing for more than one bit to be transmitted in any single baud interval.

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 wireless communication module operable to receive Wi-Fi communications on a local area 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 programming instructions from the received optical signal to enable the wireless communication module to receive digital messages via the Wi-Fi communications on the local area network.

Method of optically transmitting digital information from a smart phone to a control device

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.

Communication System for a Radio-Frequency Load Control System

A communications system and protocol for use in a non-dominant bit radio network. The radio network includes transceivers which communicate with other transceivers to allow network variables to be shared by all transceivers. The protocol allows the network to handle collisions between competing transmissions from different transceivers. The protocol also handles communications between transceivers that are out of transmitting range of each other.

Collision detection in a non-dominant bit radio network communication system

A communications system and protocol for a radio communications network including a number of transceiver devices. The protocol ensures that network variables to be shared by all devices are correctly received and updated by all devices. The protocol also provides for accurately detecting the transition from one time slot to another, in a given data transaction.

Radio network communication system and protocol

Disclosed are a method, system and protocol for processing a Transmission within a wireless network, the network including at least one device that transmits the Transmission and at least one device that receives the Transmission. The method provides for receiving the Transmission at the device that receives the Transmission; determining whether the device that receives the Transmission has previously received the Transmission; and actioning the received Transmission only if the device that receives the transmission has not previously received the Transmission.

Wireless network communications system

A radio frequency communications network (10) system and protocol for allowing the dissemination of data to be shared by devices (A,B) within the network. The invention is particularly useful when the devices are out of transmission range of each other. The network (10) includes the use of repeater devices (40) located between the devices (A,B) to manage the data transfer in the network. The invention also provides for data transfer management in the presence of collisions between conflicting data transmissions.
