摘要： Systems and methods are provided for facilitating variable precision tuning of an amplifier circuit. In accordance with one aspect of the present disclosure, the system includes an amplifier having multiple tuning stages to set the gain of the amplifier to discrete gain levels. In particular embodiments, the tuning stages are connected in series and each of the tuning stages includes a resistor connected in parallel to a switch, which can be disengaged to cause the amplifier to set the gain to an adjacent gain level. In certain embodiments, the difference in gain between each adjacent one of the plurality of gain levels is more at higher gain levels than at lower gain levels.

摘要： A pivot assembly is provided for pivotally attaching a pivotable seat component to a fixed seat component. The fixed component includes first and second apertures, first and second outer surfaces and first and second inner surfaces adjacent the apertures, and the pivotable component includes at least one pivot hole therein. The pivot assembly includes a bolt having a head, a cylindrical portion and a threaded portion. A threaded nut is engageable with the threaded portion of the bolt. A generally cylindrical plastic bushing is fitted over the cylindrical portion of the bolt and includes a peripheral lip abutting the head of the bolt and a plurality of swageable flanges extending at least partially over the threaded portion of the bolt. The swageable flanges cooperate to form a generally cylindrical shape having an outside diameter which is smaller than the first aperture and the pivot hole for insertion therethrough and larger than the second aperture for swaging against the second inner surface as the nut and bolt are threadedly engaged.

摘要： A flat panel x-ray imager exhibiting reduced ghosting effects and overvoltage protection by appropriate leakage current characteristics of the thin-film transistor array. A top electrode of a suitable material is directly on a non-insulating organic layer. The organic layer is directly on an amorphous selenium-based charge generator layer allowing charge transport across the layer, thereby reducing ghosting. The thin-film transistors have leakage current that rises relatively slowly with voltage across the transistor within a range that matches exposure through an object being imaged but rises at a sufficiently higher rate within a higher range to provide protection even when a corresponding region of the charge generator layer receives greater amounts of x-rays.
