Abstract: Audio network interface devices that are configured to be used with different types of microphones, and analog or digital audio devices. There is a housing that carries at least one set of electrical connectors adapted to be electrically connected to a microphone or audio device. The microphone connector including at least one general purpose input, at least two general purpose outputs and DC power. There is a first network connector that is adapted to provide connection to a data network, and a second network connector that is adapted to provide connection to a different electronic device. A microphone phantom power source is configured to provide phantom power to a microphone that is connected to a set of electrical connectors. A processing system is configured to cause the conversion of input and output signals from/to a microphone or other audio device that is connected to a set of electrical connectors, to/from digital output signals that are provided to the first network connector.

Abstract: A portable remote control controls a target electronic device. The portable remote control includes a data receiver having an input port for receiving a variable parameter value of a target device, a real time clock for keeping the time of day, a wireless signal transmitter for transmitting the parameter values and the time of day.

Abstract: An electrical power control system is adapted for controlling power and lighting in a building. Switch controls have either relays or triacs, controlled by microprocessors, to switch power on electrical branch circuits. An interface device 122 communicates with the switches 124,126, arranged in a multidrop configuration, with variable length data packets over serial branch circuits or data buses 142. In addition to being controlled by the interface device 122, the switch controls also have local switch actuators. The actuation of the local switch controls can be used by the interface device 122 as a control inputs to initiate other actions. Adaptive polling of switch controls is used to minimize system response time, and both transmit and receive signals are carried between the switch controls and the interface device 122 at different times on the same twisted pair wires. The interface device 122 can also communicate with a home automation system controller.

Abstract: A dimmer for use in lighting control in which a triac control circuit in included which allows for control of both incandescent and low voltage lighting systems at low and high intensities 142,144. The triac control circuit includes a microcontroller 130 which alters the duration of the gate triggering pulse for the triac 134 based upon the desired intensity level of the load. This dimmer is used in a lighting control system and the dimmer is responsive to a system controller 2 as well as to momentary switch inputs which are made directly to the dimmer. The triac control circuit can also be used with other inductive loads.
