    Abstract: An auto-darkening filter of a welding shield has a brightness-sensing unit, an optical shutter and a processor. The brightness-sensing unit generates a first signal or a second signal. In a high-sensitivity mode, the processor controls the optical shutter to operate in a dark state or a bright state depending on intensity of the first signal being higher or lower than a threshold value. In a low-sensitivity mode, the processor controls the optical shutter to operate in the bright state when intensity of the second signal is lower than the threshold value, and automatically change to the high-sensitivity mode from the low-sensitivity mode when intensity of the second signal is higher than the threshold value.

    Abstract: A light sensor is provided that includes an exposed light transducer for accumulating charge in proportion to light incident thereon over an integration period; and a light-to-pulse circuit in communication with the exposed light transducer, the light-to-pulse circuit operative to output a pulse having a pulse width based on the charge accumulated by the exposed light transducer. The light-to-pulse circuit may include a one shot logic circuit that contributes to generation of the pulse. The light sensor may include an input/output pad, a capacitor provided at the input/output pad for blocking static electricity, an input low pass filter provided at the input/output pad for blocking electromagnetic interference, and/or a bandgap voltage reference circuit connected to a power source having a supply voltage level in a range of about 3.3V to about 5.0V, and for generating a set of stable reference voltages throughout the supply voltage level range.

    Abstract: According to an embodiment of the invention, signals coming from a number of pixels or sub-pixels are compared and those signals from pixels or sub-pixels, which are substantially brighter than the other pixels in the comparison, are excluded from contributing to the output signal, to suppress direct detection events in X-ray detectors. For this an X-ray detector apparatus (101) can comprise: —an array (102) of pixel arrangements (303), —each pixel arrangement (303) comprising at least one radiation collection device (311) for converting incident radiation into a collection device signal, —switching arrangements (313, 324, 314, 142; 313, 315, 314, 352, 142; 313, 315, 314; 361) for providing to respectively one output element (141) a signal derived from the collection device signals of a plurality of radiation collection devices (311) of at least one pixel arrangement (303).
