Abstract: A cable modem (CM) device captures signals over a wide spectrum including one or more cable frequency bands and sub-bands, and extracts one or more cable channels from the captured signals. The CM device is operable to analyze the extracted one or more cable channels and assigns a portion of the extracted one or more cable channels for upstream and/or downstream communication based on the analysis. The CM device may recapture one or more previously unused cable channels to be utilized for the upstream and/or downstream communication based on the analysis. The CM device may determine noise, interference and/or blocker information corresponding to the extracted one or more cable channels based on the analysis. Based on the determined noise, interference and/or blocker information, the cable modem termination system (CMTS) may assign or block usage of one or more cable channels for the upstream and/or downstream communication.

Abstract: A wideband receiver system is provided to concurrently receive multiple RF channels including a number of desired channels that are located in non-contiguous portions of a radio frequency spectrum and to group the number of desired channels into a contiguous frequency band. The system includes a wideband receiver having a complex mixer for down-shifting the multiple RF channels and transforming them to an in-phase signal and a quadrature signal in the baseband. The system further includes a wideband analog-to-digital converter module that digitizes the in-phase and quadrature signals and a digital frontend module that transforms the digital in-phase and quadrature signals to baseband signals that contains only the number of desired RF channels. that are now located in a contiguous frequency band. An up-converter module up-shifts the baseband signals to a contiguous band in an IF spectrum so that the system can directly interface with commercially available demodulators.

Abstract: A thermal infrared imaging device (10) includes a thermal detector (50) having a linearly-arrayed plurality of spaced apart detector elements (50', 50", 50"', . . . ). A scene to be viewed is scanned across the detector (50) with successive fields of the scene shifted according the spacing between adjacent detector elements (50', 50", 50"', . . . ) in order to capture image information for the entire scene by interlacing of successive scan lines from the plurality of detector elements (50', 50", 50"', . . . ). Each complete scan of the viewed scene across the detector (50) creates an image field including a scan line for each detector element (50', 50", 50"', . . . ). Each scan line includes plural pixels, or picture elements of the viewed scene, each having a value indicative of the thermal infrared brightness of the viewed scene at the corresponding location along the scan line. An scan-line sum for each scan line is created by adding the absolute values of the pixel values for each scan line. The average of these scan-line sums is employed as a gain control factor to control the brightness of a visible image replicating the viewed scene. Further, the value of a median of the scan-line sums is used to limit gain variations which would otherwise be effected were the line-sum averages alone used to control the gain factor. Accordingly, even when a localized highly-radiant heat source (such as a fire) is within the field of view of the thermal imaging device, then in areas of the image away from the brightness caused by the fire the image does not go dark and a visible image good contrast is still maintained allowing features of the image to be viewed.

Abstract: The present system provides a thermal imaging device including a detector array responsive to thermal infrared radiation. The detector array has a linearly-arrayed plurality of spaced-apart detector elements defining cooperatively a length dimension for the detector array. Each of the plurality of detector elements provides a corresponding individual electrical signal indicative of the thermal infrared radiation incident thereon. The detector elements vary from one another in the plurality of detector elements, and the thermal imaging device responsively provides a visible-light image replicating a viewed scene. The thermal imaging device includes a scanning device scanning the viewed scene across the plurality of detector elements in a direction generally perpendicular to the length dimension. The scanning device includes a first portion scanning the viewed scene across the entire plurality of the plurality of detector elements, and a second portion scanning the viewed scene across the plurality of detector elements with transposition of the viewed scene such that a portion of the viewed scene scanned by the first portion across a certain detector element is scanned across a detector element next-adjacent to the certain detector element.
