Abstract: A multiplexed fiber optic sensor system. The system has an array of sensor elements, each responsive to a respective measurand, a light source, a fiber optic waveguide for directing light from the source to the array, a scanner for providing relative motion between the array and the light, a beamsplitter for receiving return light from the array so that the return light can be detected for analysis, and a photodetector for receiving the return light and providing an output signal in response thereto. The scanner is operable to scan the light over the sensor elements so that return light be collected from each respective element, whereby data can be determined concerning each respective measurand.

Abstract: In a semiconductor p-i-n photodiode an undoped absorption region (10) is epitaxially grown between two highly doped regions (14, 16). In prior art lattice matched InGaAs p-i-n photodiodes current epitaxial structures use low InP cap (16) doping (n˜2.5−6×1016/cm3), and nominally undoped (not intentionally doped, n˜1×1013−5×1014/cm3) InGaAs absorption regions (10). The shunt resistances of p-i-n photodiodes according to the present invention with intentional doping between n˜5×1017/cm3 and 1×1014/cm3, in the InGaAs absorption region (52, 60) are significantly increased over that of a standard structure (non-intentionally doped).

Abstract: The present invention provides a method for communicating signaling messages associated with a communication system whereby a network within the communications system is responsible for setting up a signaling path between users of the communication system. However, once that signaling path is established by the network, the users may communicate with each other whereby the network is not needed to pass data between the users thereby substantially decreasing demand on the network and freeing it for other system functions.

Abstract: A circuit and method for personalizing an electronic device (20) through a personal area network (22). Electron devices (20) have transceivers (38) for transmitting a self-initiated message that includes an identification code of the electronic device. Transceivers (38) are also capable of receiving a self-initiated message sent from other electronic devices. The received message causes a response message to be transmitted in response to the identification code in the self-initiated message. Communication between two electron devices (20′ and 20″) is established when the devices are determined to be compatible. The application of the electronic device is configured based on the response message and data is displayed by the electronic device based on the application.

Abstract: A cell relay network (38, FIG. 2) transmits cells having different priorities through a single virtual connection using several methods (100, FIG. 4; 200, FIG. 5; 300, FIG. 3). Congestion control is accomplished by a negotiation process between a network user's communication equipment at a source node (900, FIG. 9) and a network control element (1000, FIG. 10) associated with the network fabric 18 at the time of connection set-up. A source node (900) initially transmits a request for a connection to the network control element (1000). Along with a connection request, the source node also transmits a requisition for permission to transfer through the network during a predetermined time interval cells having multiple priorities. The network control element responds to the requisition by sending to the source node a connection admissions attributes message (44, FIG. 2) containing allowable connection attributes.

Data packet formatter controller (438) controls the insertion of ATM cells into the buffer (434), and also optionally compresses the ATM cells to increase the apparent bandwidth of the system.

Abstract: A wireless, peer-to-peer, capability addressable network (22) is disclosed. The network (22) accommodates any number of peers (20). Network connections are formed based upon proximity between peers (20) and upon a needs and capabilities evaluation (82).
