摘要： The x-ray imaging system comprises an x-ray source for producing an x-ray beam and an x-ray detector. The x-ray detector comprises a solid state integrated circuit having a silicon substrate and a plurality of charge storage devices. A circuit is provided for placing a charge on the charge storage devices and the integrated circuit is disposed in an x-ray permeable material. The detector is positioned in an x-ray beam such that the charge is dissipated by secondary radiation produced by interaction between the x-ray beam and the silicon substrate of the integrated circuit.

摘要： The x-ray detector comprises a plurality of closely adjacent radiation sensing arrays facing a plurality of preprocessing circuits. Bump bonds are connected directly from said sensing arrays to said preprocessing circuits. Added absorber material may be included next to the sensing arrays for converting impinging x-rays to free electrons for affecting a charge on the sensing arrays. Alternately, a scintillator may be positioned between the sensing arrays and the preprocessing circuits and sensing cells in the sensing arrays may be exposed to the scintillator.

摘要： A tuning module tunes a dual frequency PLL synthesized tuner to a desired channel frequency. The dual frequency PLL synthesized tuner includes a first PLL and a second PLL. The tuning module receives a carrier-to-noise ratio ("CNR") for each of one or more signals output from the dual frequency PLL synthesized tuner. The tuning module then generates first PLL parameters and second PLL parameters based on the CNRs and the desired channel frequency. Finally, the tuning module programs the first PLL with the first PLL parameters and programs the second PLL with the second PLL parameters.

摘要： A pool cleaning device for a pool having a powered water circulation and filtration system including at least one return inlet. The inlet is directed to create a circular flow pattern of water in the pool so as to cause debris therein to become concentratedly swirled at the pool bottom. The pool cleaning device of the present invention is provided adjacent to the drain on the pool bottom and provides a vortex of water extending upwardly from the pool bottom. The device includes a housing having at least one inlet and at least one outlet. A shroud is connected to the housing and has at least one inlet and at least one outlet. The debris moves from the shroud inlet to the shroud outlet due to the vortex. A debris collection device is connected to the shroud. Movement of the water and the debris is permitted into the debris collection device and the debris is limited from returning to the shroud. The device may be sealingly seated over the drain on the pool bottom whereby the device directs a portion of the pool water downward to the drain which provides power to produce the upward vortex. Thus, the device is powered by the normal suction force at the drain caused by the water circulation and filtration system.
