Abstract: An ecosystem vision-making application includes a web server that delivers data from a database for a geographic model together with JavaScript scripts that implement the model, both being delivered to a JavaScript-enabled web browser on a client. Using tools defined by the vision-making application, vision parameters are defined for a vision applicable to a geographic location. Execution of the JavaScript scripts by the web browser enables calculation of an environmental performance indicator which includes metrics for ecologically significant performance indicators for the vision applied to the geographic location. Other performance metrics may be calculated, such as social metrics, economic metrics and livability metrics. These metrics may also be calculated for baseline visions and for visions from other users, thereby enabling comparison with the user-defined vision, and so as to provide for evaluation, change, improvement, commentary, distribution and sharing of the vision.

Abstract: An apparatus for compensating for optical loss includes a plurality of optical fibers joined to form a plurality of output ports and a fiber junction. A signal amplification device is positioned between the fiber junction and each of the plurality of output ports to communicate with the plurality of optical fibers. An optical transmission signal entering the input port of the apparatus is equally divided at the fiber junction and guided by separate optical fibers toward each of the output ports. Each signal amplification device communicates with the fibers to amplify the optical signals as they pass between the fiber junction and the output ports to compensate for the coupling and other losses experienced by the optical signals due at least in part to the use of the apparatus itself.

Abstract: An apparatus for compensating for optical loss includes at least two optical fibers joined to form a plurality of ports and first and second coupled regions positioned between the ports. Each coupled region includes a signal transmission region adapted to transmit an optical signal. A semiconductor optical amplifier having an active layer is positioned between the first and second coupled regions such that the active layers is substantially aligned with the signal transmission region to provide a pathway for and amplification to an optical signal passed through the apparatus. A method of compensating for optical loss, a loss compensating optical communication system, and a process of manufacturing an optical signal loss compensating device are also disclosed.

Abstract: A reconditioning system for extending the reach of a RF communication signal using a high voltage cable and a neutral conductor as a communication channel. A reconditioner of the reconditioning system is either a repeater or a regenerator and is coupled to the high voltage cable using novel high voltage couplers. The system has an isolation filter for segmenting the high voltage cable in order to limit interference of RF signals on different parts of the high voltage cable.

Abstract: A communication system is disclosed for providing broadband multimedia services using one or more high-voltage cables of a power distribution network, while the power distribution network is supplying electrical power. A radio-frequency signal at a first location is coupled to the high-voltage cable, transported over the high-voltage cable, and then coupled from the high-voltage cable at a second location. The radio-frequency signal at the first location is modulated with information and demodulated at the second location, thereby providing broadband multimedia service between the two locations. The broadband multimedia communications system may be used for a variety of communication needs, such as telephone service, video service, internet service, and other services requiring high-speed data transfers.

Abstract: A system and method for reducing signal attenuation of integrated services digital network (ISDN) digital transmissions at the subscriber loop, thereby increasing the available subscriber loop range, is provided. An ISDN digital transmission system is used for transmitting and receiving digital information via a line termination at a central office. Customer premises equipment is coupled to a network termination (NT-1) within the customer premises, which is in turn coupled to interface the line termination at the central office. A plurality of inductive load coils are coupled in series with the two-wire subscriber loop ISDN BRI at predetermined distance intervals, which are calibrated to resonate the two-wire bus.

Abstract: A coupling system for transferring a RF signal to and from a high-voltage cable (302) of a power distribution system is described. In one embodiment the coupling system uses a lightning arrester (314) as an element for coupling a RF signal from a RF modem (420) to and from the high-voltage cable. An impedance element of the coupling system is a section of a grounding cable (309) modified with one or more ferrite cores (430) as a means for adjusting the value of the impedance.

Abstract: An apparatus and method for recovery of symbol timing for asynchronous data transmission utilizes an RF downconverter (11), an A/D converter (12), and a digital signal processor (14). The digital signal processor (14) includes an error detection block (130), a timing correction block (135), a counter (140), a programmable capture register (145), a clock (150) to produce clock signals, and preferrably a differential detector (155). The error detection block (130) provides information, an error parameter, concerning phase and frequency variances between the clock signal and a transmitted signal. The timing correction block (135) utilizes the error parameter to determine an updated, programmable value stored in the programmable capture register (145).

Abstract: A fluid flow control device including an inlet and a pair of outlets and a diverter valve selectively operable to place the inlet in fluid communication with either the first or second outlet in response to a humidity sensitive control mechanism. The fluid flow control device is particularly adapted for utilization with an automatic clothes dryer in which the inlet is coupled to the exhaust outlet of the dryer and the valve is actuated to open the first outlet, communicating with the outside of the house, for example, when the humidity within the exhaust air exceeds a threshold value, and to open the second outlet, which is in communication with an interior space or with a duct in a hot air circulating system, when the humidity of the dryer exhaust air is below the threshold value.
