摘要:
Disclosed is a direct current power line communication apparatus, by which communication between electronic apparatuses with a direct current voltage line there between can be stabilized. The direct current power line communication apparatus, i.e., a direct current power line communication apparatus that transmits signals using the direct current voltage line (15a), is provided with: a PLC communication control unit (29), which controls the transmitting unit (27) connected to the direct current voltage line (15a); and a voltage detecting unit (30), which detects the voltage of the direct current voltage line (15a), and notifies the PLC communication control unit (29) of the detected voltage. The PLC communication control unit (29) transmits information, including the voltage information, to other direct current power line communication apparatus via the transmitting unit (27).

In conjunction with a wiring in a house carrying data network signal, a modular outlet (100) includes a base module (100a) and interface module (100b). The base module connects to the wiring and is attached to the surface of a building. The interface module provides a data unit connection. The interface module is mechanically attached to the base module and electrically connected thereto. The wiring may also carry basic service signal such as telephone, electrical power and cable television (CATV). In such a case, the outlet provides the relevant connectivity either as part of the base module or as part of the interface module. Both proprietary and industry standard interfaces can be used to interconnect the module. Furthermore, a standard computer expansion card (such as PCI, PCMCIA and alike) may be used as interface module.
摘要:
A serial intelligent cell (SIC) and a connection topology for local area networks using Electrically-conducting media. A local area network can be configured from a plurality of SIC's interconnected so that all communications between two adjacent SIC's is both point-to-point and bidirectional. Each SIC can be connected to one or more other SIC's to allow redundant communication paths. Communications in different areas of a SIC network are independent of one another, so that, unlike current bus topology and star topology, there is no fundamental limit on the size or extent of a SIC network. Each SIC can optionally be connected to one or more data terminals, computers, telephones, sensors, actuators, etc., to facilitate interconnectivity among such devices. Networks according to the present invention can be configured for a variety of applications, including a local telephone system, remote computer bus extender, multiplexers, PABX/PBX functionality, security systems, and local broadcasting services. The network can use dedicated wiring, as well as existing wiring as the in-house telephone or electrical wiring.

摘要:
The present embodiments provide methods, apparatuses, and systems for use in implementing security systems. Some embodiments provide methods that receive a remote alarm message broadcast across an external power line communication (PLC) network at a first internal PLC security system coupled with the external PLC network from a remote second internal PLC security system coupled with the external PLC network with the remote alarm message comprising an alarm identifier of a local alarm message from the remote second internal PLC security system, and trigger a local alert at the first internal PLC security system indicating that the remote alarm message has been received across the external PLC network.

摘要:
A communication system associated with premises power distribution lines can be used to transmit audio data via the distribution lines. First and second transceivers can communicate bi-directionally over the distribution lines to transmit the audio data. The audio data can be provided by a computer coupled to one of the transceivers. One or more portions of the premises power distribution lines can be used as radiators to wirelessly transmit the audio data to one or more devices.
