International Classification:

G06F 1546

US Classification:

700 19, 700 47, 702182

Abstract:

A programmable control system includes a control module having one or more inputs to which an external sensor device may be connected, and one or more outputs to which an external actuator device capable of manual override and providing a status feedback signal may be connected. One or more signal inputting devices are provided which a human operator can utilize to enter a learn mode. A display can be used to indicate a mode of the control system, and a memory can be used to store the characteristics of an external sensor device connected to an input and an association between inputs and outputs. A controller/processor has both a learn mode and a run mode. The control module may interface with external actuator devices such as circuit breakers located in one or more panels via an intelligent control bus and an address module.

International Classification:

H04H 1/00

US Classification:

455 301, 455 6711, 4551511, 455140

Abstract:

A media content monitoring system uses a rack adapted to receive multiple carrier boards to improve the system's ability to be configured to specific applications. Each carrier board contains tuner modules for receiving AM/FM broadcasts, satellite radio broadcasts, TV audio broadcasts, HD, IBOC, DAB and DRM digital radio broadcasts, etc. The tuner modules produce a USB output that is combined by a USB hub on the carrier boards into a single USB output. The carrier board outputs are in turn combined by a rack based USB hub into single USB output that is provided to a host computer. The host computer includes content identification software that automatically identifies selected media content received by the tuner modules and stores the selected content in a database. The host computer can send control codes to the tuner modules to alter their reception parameters.

US Classification:

Abstract:

An electrical distribution system having a load center for programmably and remotely controlling a plurality of circuit breakers, an expander unit coupled to the load center and a plurality of external switches for providing signals to the load center representative of the status of the switches. The load center contains a control module that continually receives inputs from the expander unit via an interface module. It also contains a keyboard and display for programming instructions for closing and opening the individual circuit breakers and for displaying the status of the circuit breakers. The interface module, coupled to the control module, causes the circuit breakers to open and close according to programmed instructions received from the control module or another external device. The expander unit contains a plurality of input circuits coupled to external switches. An expander circuit having a microprocessor receives signals from the input circuits, which are representative of the status of the external switches, and continually provides signals representative of the status of the switches to the load center for the load center to cause the circuit breakers to open and close as a function of the status of the external switches.
