摘要： A method and system for masking a surface to be etched is described. A droplet source ejects droplets of a masking material for deposit on a thin-film or other substrate surface to be etched. The temperature of the thin-film or substrate surface is controlled such that the droplets rapidly freeze upon contact with the thin-film or substrate surface. The thin-film or substrate is then etched. After etching the masking material is removed.

摘要： The compact document imager and display apparatus has a two-dimensional image sensor array, a flat panel display such as a liquid crystal display (LCD), and processing electronics. An illumination source can be added to illuminate the document on the sensor array and to provide backlight for the LCD. Color imaging may be achieved by providing three sequential illumination pulses of appropriate colors. A document is placed in close contact with the sensor array. The document is illuminated and an electronic image is captured and stored in the processing electronics. The captured image can be displayed on the LCD by the processing electronics. The document, such as a single sheet of paper or a transparency, can be illuminated by the room light to perform image capture. The compact document imager can be used as a facsimile machines by providing telephone connections. Documents can be scanned using the sensor array and sent to other devices. Documents can be received from other sources and displayed on the LCD. A light-pen can be used to generate handwritten documents or highlight portions of documents. An X-ray imaging device is created by placing a thin phosphor sheet in contact with the sensor array. The x-ray imaging device is placed over an object illuminated by X-rays and the image produced by the glowing phosphorous is stored and displayed by the LCD.

摘要： Image transduction device pixel cells are described which have analog memory integrated with the pixel transduction elements and arrays made from such pixel cells. The integrated pixel cells are capable of storing information which, for example, can achieve a desired transduction transfer function for a given pixel transduction element. While the present invention may be used with any type of continuously variable, settable, and nonvolatile analog memory, the analog memory is beneficially based on a ferroelectric gate transistor comprised of an amorphous silicon transistor integrated with a ferroelectric gate dielectric layer or an amorphous silicon transistor with a charge storage dielectric gate layer.

摘要： A radiation detector employing amorphous Si:H cells in an array with each detector cell having at least three contiguous layers (n type, intrinsic, p type), positioned between two electrodes to which a bias voltage is applied. An energy conversion layer atop the silicon cells intercepts incident radiation and converts radiation energy to light energy of a wavelength to which the silicon cells are responsive. A read-out device, positioned proximate to each detector element in an array allows each such element to be interrogated independently to determine whether radiation has been detected in that cell. The energy conversion material may be a layer of luminescent material having a columnar structure. In one embodiment a column of luminescent material detects the passage therethrough of radiation to be detected and directs a light beam signal to an adjacent a-Si:H film so that detection may be confined to one or more such cells in the array. One or both electrodes may have a comb structure, and the teeth of each electrode comb may be interdigitated for capacitance reduction. The amorphous Si:H film may be replaced by an amorphous Si:Ge:H film in which up to 40 percent of the amorphous material is Ge. Two dimensional arrays may be used in X-ray imaging, CT scanning, crystallography, high energy physics beam tracking, nuclear medicine cameras and autoradiography.

摘要： Systems and methods are described that facilitate using TFT control of electronic discharge for surface potential reduction and latent image formation on an imaging member. Corona charging is performed to first create a background surface potential, followed by selective discharge of individual pixels using an array of TFTs to supply free charge carriers to reduce the electrostatic surface potential to nearly zero. This is followed by discharged area development (DAD) to develop the latent image on a print medium (e.g., paper). The described systems and methods do not require a HVPS to drive the backplane; therefore, the TFT matrix is electrostatically decoupled from the developer and other system components in direct contact with the imaging member. Accordingly, known addressing systems may be used to address the TFT array.

摘要： Systems and methods are described that facilitate eliminating a need for a raster output scanner (ROS) or laser when generating a latent image on a photoreceptor. An addressable backplane is employed, comprising an array of field effect transistors (e.g., silicon or organic thin film transistors, or TFTs), wherein each TFT corresponds to a single pixel on a charge transport layer on the photoreceptor surface. Latent image formation is performed by forming a surface potential using corona charging, and then directing free charge carriers toward the photoreceptor surface to reduce electrostatic potential in areas that need to be toned. TFTs in the array are individually addressed, or selected, to connect to a common ground, which allows photodischarge to occur only in selected areas (e.g., pixels associated with the selected TFTs). Once the array of TFTs is addressed, an LED light source emits light over the surface of the photoreceptor, and only the selected (grounded) TFTs permit their associated pixels to discharge. In this manner, a latent image is formed without a need for a bulky and expensive ROS.

摘要： A first side has a first surface on which is located a material, at least a portion of which is to be formed into at least one tip. A second side has a second surface which is heated. At least one of the first and second surfaces being moved so material located on the first surface comes into physical contact with the second surface. Then at least one of the first side and the second side are moved, wherein the physical contact between the material and the second surface is maintained, causing the material to stretch between the second surface and the first surface, generating at least one capillary bridge. Movement is continued until the physical contact between the material and the second surface is broken resulting in the formation of at least one sharp conductive tip.
