Abstract:
A fiber optic communications network provides an expanded and enhanced Intercommunications System (ICS) which enjoys increased immunity to electromagnetic interference (EMI), can be easily expanded, can present a similar look and feel and functionality offered by existing networks, and does not present a single point of failure. Voice, video, and data may be transmitted bi-directionally on a single optical fiber. Utilizing a single wavelength of light, the network may be supported as part of a more complex multi-purpose, multi-wavelength installation.
Abstract:
An optical network has an optical bus interconnecting a plurality of sources with a plurality of loads. Each source has a tunable laser for transmitting signals at a selective wavelength and each load has a tunable filter for receiving signals at a selective wavelength. As a result, through a single connection per node and a single bus, each source can exchange signals with any load. The optical network employs a passive optical interface device for routing signals between a node and a bus. The optical interface device provides balanced amplification of the optical signals throughout the network. The optical network is able to distribute RF and other analog signals to multiple nodes while preserving signal quality.

An active sampler antenna capable of transmitting signals is disclosed. The active sampler antenna includes a first set of conducting surfaces, a second set of conducting surfaces, a power source, and multiple switches. The second set of conducting surfaces is located substantially parallel to the first set of conducting surfaces. The power source has two terminals, namely, a first terminal and a second terminal. The first terminal of the power source is connected to the second set of conducting surfaces. Each of the switches is connected between a respective one of the first set of conducting surfaces and the second terminal of the power source. The switches allows a defined amount and timing of charges to be delivered from the power source to the first set of conducting surface for signal transmissions.

Abstract:
Optical networks may be deployed within hospitals and other structures for permitting bi-directional optical communication. The networks include couplers that permit the network to branch out into multiple sub-networks and hubs. Each of these couplers functions as a junction box and can be used to couple with other networks, such as the Internet or other third party service providers, and can also be used to branch off signals off o main backbone. Furthermore, these couplers may be used to couple signals off of the backbone or a subnetwork toward a specific individual unit. The networks include bi-directional optical amplifiers which compensate for losses associated with the various couplers dispersed throughout the network.
Abstract:
A vehicle is equipped with a network that permits multiple units to communicate with each other over a common optical bus. The optical bus is bi-directional and couplers direct optical signals that travel in both directions along the bus toward the various units connected to the bus. These couplers also direct optical signals from each unit onto the bus in both directions. The units may form part of one or more systems, such as an entertainment system, engine system, or data and communication system. The optical networks are immune to electromagnetic noise that may be generated within the vehicle and significantly reduce the amount of cabling compared to conventional electrical networks. The optical network can accommodate large numbers of units and systems by employing amplifiers dispersed throughout the network. The amplifiers compensate for splitting losses associated with the couplers and may be located along the bus or within the couplers.
