Abstract: An apparatus for capturing information associated with an x-ray image recordable on an x-ray imaging plate. The apparatus includes a receiving area, a display, a replaceable rechargeable power supply, one or more non-image sensors, and a computer system. The receiving area receives the x-ray image plate or attaches the apparatus to the x-ray imaging plate. The non-image sensors collect information associated with the x-ray image recorded on the x-ray imaging plate. The computer system includes memory, and is configured to receive, measure, store, and subsequently communicate to another computer system, the collected information associated with the x-ray image recorded on the x-ray imaging plate.

Abstract: A circuit for detecting light comprising: a) a light-integrating photosensor circuit responsive to light for producing a variable voltage signal representing the accumulation of the light over time; and b) a measurement circuit for receiving a time measuremrfent signal and the variable voltage signal to produce an output value representing the time required for the variable voltage signal to reach a predetermined voltage level, wherein the output value is proportional to the light accumulated during the required time.

Abstract: A method of writing an image on a liquid crystal display of the type having a layer of cholesteric liquid crystal material disposed between a pair of unpatterned conductors and a light absorbing layer for forming an image wise thermal pattern in response to an image wise pattern of light, including applying a first voltage to the conductors; applying a second voltage different from the first voltage to the conductors after applying the first voltage, wherein the first and second voltages are non-zero; and exposing the liquid crystal display to the image wise pattern of light.
