  • Publication number: 20070085015
    Abstract: An x-ray detector, which is portable, light, and rugged, includes layers of foam that encase its imaging panel. The electronics are situated outside the footprint of the imaging components. The components of the detector are housed within an impact-absorbing cover assembly.

  • Publication number: 20060197025
    Abstract: A method for localizing optical emission is disclosed. The method involves identifying a first readout channel of a first pixellated photodetector array based on an impact of a first photon on the first pixellated photodetector array. The first photon is emitted by a scintillator unit of a scintillator array and the first readout channel corresponds to a column of one or more pixels of the first pixellated photodetector array. The method also involves identifying a second readout channel of a second pixellated photodetector array based on an impact of a second photon on the second pixellated photodetector array. The second photon is emitted by the scintillator unit and the second readout channel corresponds to a row of one or more pixels of the second pixellated photodetector array. The method further involves identifying the scintillator unit based on the first readout channel and the second readout channel.

  • Publication number: 20060197022
    Abstract: A method for identifying localized optical emission is disclosed. The method involves identifying a region, which corresponds to a plurality of scintillator units of a scintillator, on a position sensitive photodetector that is impacted by one or more photons. The method further involves identifying a readout channel of a pixellated photodetector array that corresponds to a pixel associated with a scintillator unit impacted by the one or more photons. The method, further involves, identifying the scintillator unit based on the region and the readout channel.

  • Patent number: 5576859
    Abstract: A device for improving a contrast of a liquid crystal screen by using an opaque mask. The display screen includes a first plate, on one face of which are deposited elements with controlled transparence or reflectance and thin film components controlling these elements, and a back plate covering a face of the first plate including the elements with controlled transparence or reflectance and the thin film components. The elements are separated by opaque bands into lines and columns forming a grid. The opaque bands are deposited at least partially on the plate including the elements and the thin film components.
