A thermally conductive stripline RF transmission cable has a flat inner conductor surrounded by a dielectric layer that is surrounded by an outer conductor. The dielectric layer may include a base polymer and a thermally conductive material to increase a thermal conductivity of the cable. A thermal conductivity of the dielectric layer may be increased between a midsection of the inner conductor and the outer conductor. A jacket may surround the outer conductor, the jacket including a base polymer and a thermally conductive material. Additional conductors may be applied within the dielectric layer and/or in the jacket, proximate the outer conductor.

A system for processing video signals to compensate for distance-induced video signal delays includes a camera controller and distant camera are arranged so that the camera controller generates and sends a synchronization signal to the camera, which upon receiving it generates and sends back to the camera controller a reference signal starting at a fixed time following camera receipt of the synchronization signal, and further arranged so that the reference signal upon receipt by the camera controller is compared by the reference pulse comparator to determine if it is late, early, or at an acceptable time, upon which determination a phase adjustment signal is generated and sent by the camera controller to the camera second timing generator phase offset adjustment section to adjust appropriately the timing of the insertion of a video signal onto the transmission line by the camera.

A video signal routing system includes a video signal carrying line arranged in a loop beginning and ending at a signal multiplexer, a plurality of video cameras electrically connected to the line at points spaced therealong, and a video output line connected to receive video signals from the multiplexer. A synchronization signal insertion device and a code signal insertion device are located in the video signal carrying line adjacent the beginning of the loop between the multiplexer and the cameras. A duplicate synchronization signal insertion device and a duplicate code signal insertion device are located in the video signal carrying line adjacent the end of the loop between the multiplexer and the cameras. A timing generator and interface receives signals from a synch detector and a video level detector in the video output line and is controlled by a microcontroller. The microcontroller and the timing generator and interface control the synchronization signal insertion device, the code signal insertion device, the duplicate synchronization signal insertion device, and the duplicate code signal insertion device.

A stripline RF transmission cable has a plurality of generally planar inner conductors surrounded by a dielectric layer that is surrounded by an outer conductor. The inner conductors may be aligned coplanar, inner conductor edge to inner conductor edge, separated by the dielectric layer. Alternatively, the inner conductors may be provided in a vertical stack. A shield element may be applied between the inner conductors. The shield element may be electrically coupled to the outer conductor to entirely isolate the inner conductors from one another.

The present invention provides a synchronization system comprising a base unit and at least one video camera. The base unit includes a master time-base adapted to set a time period that samples a frame of video data, a memory, and a base unit communications transceiver. The base unit communications transceiver is adapted to transmit a frame synchronization signal to a video camera communications transceiver. The video camera includes an image sensor adapted to store the video data, an exposure control adapted to control an exposure level of the image sensor, and a camera time-base adapted to receive the frame synchronization signal from the video camera communications transceiver. The camera time-base is further adapted to receive the frame synchronization signal, reset its time and initiates its internal timing sequence, transmit signals to the exposure control to control a length of the exposure, and transmit timing signals to the image sensor to read the video data.

A combustion system equipped with one or more carbonaceous fuel burning combustors (e.g., slagging Cyclone combustor) and adapted to minimize nitrogen oxide (NOx) formation during staged combustion operation by selective introduction of oxygen through at least one of the combustors to create a hot sub-stoichiometric combustion zone by reducing the diluent effect of nitrogen and other inert gases present in the oxidizer/air. A method of operating the combustion system of the invention with reduced NOx emissions is also disclosed.
摘要:
A video processing system (10) is provided that comprises an image sensor image area (14) that operates to transfer an image to an image memory (18) to be processed by a video processor (16). The exposure length of the image is controlled by an iris controller (24) which comprises a signal decoder (30). An IMAGE CLEAR signal is juxtaposed with an IMAGE TRANSFER signal to set the length of the exposure. The IMAGE CLEAR signal is generated by an iris counter (36) and an iris signal decoder (34). The maximum count used by the iris counter (36) is set using a count length set circuit (38) which receives command signals generated by monitoring the video output.

The apparatus and method (10) are applied to an image sensor (26) having an image area (32) for receiving light to form a first predetermined number of lines of image data. In certain image sensors (40, 100), a storage area (44, 108) is coupled to the image area (42, 106) for receiving a second predetermined number of lines of image data from the image area (42, 106) in response to an image area gate signal. A serial register (68, 110, 126) is further coupled to the storage area (44, 108) for receiving successive lines of image data therefrom in response to a STORAGE AREA GATE signal, and the serial register (68, 110, 126) further serially outputs the successive lines of image data in response to a SERIAL REGISTER GATE signal. The image centering command input from an operator is generated by and received from a vertical and horizontal adjust input device (12, 14) that generates a vertical adjust value and a horizontal adjust value indicative of the amount of adjustment needed for centering the image. A timing controller (24) is further coupled to the image sensor (26) and the vertical and horizontal adjust input device (12, 14) to generate the IMAGE AREA GATE, STORAGE AREA GATE, SERIAL REGISTER GATE signals, a plurality of display timing signals, and also to determine the timing relationships between the signals in response to the vertical and horizontal adjust values.

A stripline RF transmission cable has a flat inner conductor surrounded by a dielectric layer that is surrounded by an outer conductor. A jacket with an attachment feature surrounds the outer conductor. The attachment feature may be a fin aligned parallel or normal to the inner conductor. The attachment feature may be continuous or periodic along a longitudinal extent of the cable. The attachment feature may include male and female portions dimensioned to couple with one another, enabling adjacent cables to be attached to one another.
摘要:
A video system controller inserts synchronization pulses on a video camera line, which create a frame of video on the video camera line. The video system controller also inserts camera code in the active video period of a non-viewed line of the frame of video. A plurality of camera units are connected to the video camera line and use the synchronization pulses placed on the video camera line to remain synchronized with the other camera units. Upon sensing a particular camera code on the video camera line, the camera unit which corresponds with the particular camera code will insert a video image signal into the active video time period of the viewed video line for the frame of video having the particular camera code therein. The video camera code returns to the video system controller which receives the frame of video having a composite of the synchronization pulses from video system controller and the video image signal therein. The video system controller then transmits a video image signal to a video recorder or display.
