摘要： Laser imaging apparatus includes a laser which produces a laser beam. An image media is scanned with a laser beam in a raster pattern to produce a scanned image. A photodetector converts the scanned image into an image signal. An amplifier amplifies the image signal and has varying gain. A control circuit controls the laser beam scanning device to scan image media of different sizes with laser beam raster patterns of different sizes. The control circuit includes detectors for detecting the size of the image media. The control circuit varies the gain of the amplifier as a function of the detected size of the scanned image media.

摘要： A material signature detector that provides for the assessment of changes in critical material properties of materials such as pharmaceuticals and solutions is disclosed. The material signature detector is non-contact and non-invasive and provides the ability to detect unintended changes in the contents of a vial or other container during the fill-finish process, transport, compounding, or storage. The material signature detector uses a novel resonant electrical impulse spectroscopy circuit that employs quadrature demodulation at lower frequencies to detect changes in the capacitance and conductance (resistance) of the sample under test. A series of digital signatures are created at different frequencies to provide an overall assessment of changes in the properties of the material under test. These digital signatures may in turn be stored in an electronic library for subsequent analytics.

摘要： A wireless X-ray detector for a digital radiography system with remote detection of impinging radiation from the system X-ray source onto a sensor panel having amorphous or crystalline silicon photodiodes or metal insulated semiconductor (MIS) sensors. Changes in current in the photodiode bias supply circuit is sensed to generate a signal indicating presence of radiation. Improved detection of X-ray cessation is achieved either by leaving at least one line of sensors connected between the bias supply circuit to a virtual ground during charge accumulation or by using an X-ray presence detector circuit that increases the sensitivity of the detector circuit to bias circuit current changes occurring after onset of the radiation.

摘要： A low noise digital radiography image capture system employs a two-dimensional array of pixel sites in the image capture panel with each site having an analog-to-digital converter to digitize analog charge values produced by imaging radiation directly into corresponding digital data at the site prior to read-out to subsequent digital data processing electronics thereby avoiding noise and crosstalk problems associated with high frequency read-out of analog information. Fill factor problems caused by inclusion of integrated circuitry on the pixel site are minimized by inclusion of the A/D counter on the opposite side of the substrate support for the pixel site.
