A video transmission system for facilitating transmission of video and control signals, particularly infrared remote control signals, between different locations in a residence using existing telephone wiring. Simultaneous transmission of signals of both types over active telephone lines is possible without interference with telephone communications. Transmission succeeds without requiring special treatment of the video signals beyond RF conversion, despite signal attenuation inherent in transmission over the telephone line media. Two or more video sources may be tied into the system, and selected as desired. Remote control signals generated in one room may be utilized without requiring a clear line of sight between the remote control device and the receiver.

Video transmission and control system utilizing internal telephone lines

An interactive system and method for communicating data over a network of twisted pair wiring that is in active use as a conductive path for ordinary telephone signals. Data is encoded redundantly in multiple channels to avoid interference by noise on the telephone network, such as interference from common radio signals. Data is also communicated in the reverse direction using a more general procedure. This reverse channel can be located above the telephone voice band and below the multiple data channels. Data communications are accomplished without interfering with voice communications. The transmitted data may include audio/video signals, and signals from infrared transmitters.

Multi-band data over voice communication system and method

A transceiver is operable to connect to a 2-wire conductive path to communicate information in multiple channels to a companion transceiver. Data is encoded redundantly inside the channels, enabling communication to succeed even when one of the channels drops out due to noise. The channels may be selected so that they do not overlap the bands used by common radio sources. The companion transceiver decodes the data using the signals it receives from the multiple bands, and transmits information back to the first transceiver. Transmitted information may include video signals and signals from infrared transmitters.

Multichannel transceiver using redundant encoding and strategic channel spacing

An interactive system and method for communicating data over a network of twisted pair wiring that is in active use as a conductive path for telephone signals. A first channel is used for transmission of data from a signal interface to a transceiver. The data is made available to the signal interface from an external source of information. The transceiver communicates data in the reverse direction of a second channel. The transceiver can sendcontrol signals upstream to indicate which audio/video content is to be sent back. Information communicated in the reverse channel can be received as a light signal, with the light signal recreated at the opposite end of the link.

Interactive data over voice communication system and method

An acoustic signal unit comprises a signal generation unit to generate a first electrical signal, a first transducer to generate an acoustic signal in response to the first electrical signal, and a second transducer to generate a second electrical signal in response to the received acoustic signal. A calculation unit is provided to compare the first and second electrical signals to determine the time of flight of the acoustic signal, wherein the time of flight corresponds to the stress in the rolling element bearing. The stress may be calculated according to a formula or by multiplying an acoustic time constant for the rolling element bearing by the distance traveled by the acoustic signal across the rolling element bearing, and by the time of flight determined by said comparison unit.
