Publication number: 20050277328Abstract: A local area network (60) within a residence or other building, including both wired (5) and non-wired segments (53). The wired segments are based on new or existing wires (5a, 5b, 5c, 5d, 5e) in the building, wherein access to the wires is provided by means of outlets (61a, 61d), such as a telephone system, electrical power distribution system, or cable television wiring system. The non-wired segments are based on communication using propagated waves such as radio, sound, or light (e.g. infrared). The wired and non-wired segments interface in the outlet, using a module (50) that serves as mediator between the segments. The module can be integrated into the outlet, partially housed in the outlet, or attached externally to the outlet. Such a network allows for integrated communication of data units (24b) connected by wires and data units (24a, 24d) connected without wires.Type: ApplicationFiled: May 13, 2005Publication date: December 15, 2005Applicant: Serconet LTDInventor: Yehuda Binder

Patent number: 6970538Abstract: A local area network using the telephone wiring within a residence or other building simultaneously with telephony signals. The local area network uses high pass filters to access the high-frequency band across the media, whereas the standard telephone service uses low pass filters to access the low-frequency voice/analog telephony band across the same media. The electrically-conducting media connecting telephone/data outlets are split, or separated at each outlet and the outlets are modified to provide access to both ends of the resulting segments. The low pass filters at each segment end join the segments together, allowing analog telephony signals to travel throughout the network, thus supporting normal telephone service. The high pass filters at each segment end are connected to modems or other Data Communication Equipment, thus supporting data communication networks of various topologies, including point-to-point topologies.Type: GrantFiled: February 9, 2004Date of Patent: November 29, 2005Assignee: SercoNet Ltd.Inventor: Yehuda Binder

Publication number: 20050259602Abstract: A network for carrying out control, sensing and data communications, comprising a plurality of nodes. Each node may be connected to a payload, which comprises sensors, actuators and DTE's. The network is formed using a plurality of independent communication links, each based on electrically-conducting communication media comprising at least two conductors and interconnecting two nodes, in a point-to-point configuration. During network operation, nodes can be dynamically configured as either data-generating nodes, wherein data is generated and transmitted into the network, or as receiver/repeater/router nodes, wherein received data is repeated from a receiver port to all output ports. During normal network operation, the network shifts from state to state. Each state is characterized by assigning a single node as the data-generating node, and configuring all other nodes in the network as repeaters and receivers. The network can be configured in linear or circular topology, or any mixture of both.Type: ApplicationFiled: July 28, 2005Publication date: November 24, 2005Applicant: SERCONET, LTD.Inventor: Yehuda Binder

Publication number: 20050254494Abstract: A method and apparatus for enabling a local area network wiring structure to simultaneously carry digital data and analog telephone signals on the same transmission medium. It is particularly applicable to a network in star topology, in which remote data units (e.g. personal computers) are each connected to a hub through a cable comprising at least two pairs of conductors, providing a data communication path in each direction. Modules at each end of the cable provide a phantom path for telephony (voice band) signals between a telephone near the data set and a PBX, through both conductor pairs in a phantom circuit arrangement. All such communication paths function simultaneously and without mutual interference. The modules comprise simple and inexpensive passive circuit components.Type: ApplicationFiled: July 25, 2005Publication date: November 17, 2005Applicant: SERCONET, LTD.Inventor: Yehuda Binder

System and method for transmission-line termination by signal cancellation, and applications thereof
Patent number: 6937056Abstract: An active terminating device (30) for an electrical transmission line with optional line-receiving and line-driving capabilities. The basic device is a two-terminal unit, denoted as a Signal Canceling Unit (SCU), which sensesthe signal available at its terminals (34a, 34b), and applies negative feedback in order to cancel and absorb the signal. When applied to the end of a transmission line (15a, 15b) as part of wired communication network, the SCU functions as a terminator. When connected in the middle of such wired transmission line, the SCU splits the transmission line into two separate and isolated segments. In such a configuration, the SCU can be used to isolate a portion of a network from signal degradation due to noise or bridge-tap. Furthermore, the two isolated segments may each employ independent communications, such that no interference exists between the segments.Type: GrantFiled: September 12, 2001Date of Patent: August 30, 2005Assignee: Serconet Ltd.Inventor: Yehuda Binder -

Publication number: 20050117603Abstract: An improved telephone system over a single telephone line within a residence or other building is disclosed, supporting exchange features and enabling easy expansion for multiple external lines. The existing telephone wiring is used as the medium for a local data communication network carrying multiple voice channels. In each outlet, one or more voice channels are converted into a standard telephone-line interface. Life-line functionality is facilitated by using the lower band of the spectrum isolated from the data communication network, and a dedicated connector in the outlet provides access to this band. External telephone feeders are converted to digital form for interfacing to the in-home data communication network.Type: ApplicationFiled: January 3, 2005Publication date: June 2, 2005Applicant: SERCONET, LTD.Inventor: Yehuda Binder
