Abstract: A digital radiography detector has a substrate that is enclosed by a housing and that has, formed on a first surface, photosensitive circuitry that provides image data of a subject in response to ionizing radiation passed through the subject, wherein a second surface on the exterior of the detector has a multilayer flexible cover sheet configured to absorb impact force against the detector.

Abstract: A digital radiography detector has a glass panel that is encased within a housing and that has, formed on a first surface, circuitry that provides image data of a subject in response to ionizing radiation passed through the subject, wherein at least a second glass panel surface on the exterior of the detector has a flexible cover sheet that is configured to absorb impact force against the detector.

Abstract: A planar radiographic imaging device has electromagnetic radiation sensitive elements disposed in a two-dimensional array. A housing encloses the two-dimensional array of radiation sensitive elements and includes a layer of aligned carbon nanotubes on a surface thereof.

Abstract: A radiographic imaging detector has photoimaging pixels disposed in an array, control electronics for controlling operation of the array to capture radiographic images, and a voltage source for powering the array of photoimaging pixels and the control electronics. A housing with multiple parts encloses at least the array and the control electronics and provides a seating for the voltage source. A first part has a first mating surface, a second part has a second mating surface. The first and second mating surfaces are disposed adjacent to each other and define a gap therebetween with a hydrophobic material deposited along at least one of the first and second mating surfaces.

Abstract: A coiled tubing set inflatable packer, bridge plug and releasing tool therefor. The packer and bridge plug comprise an adapter with a mandrel slidably disposed therein. A pressure actuated piston releases a locking ball between the mandrel and adapter during an inflation cycle and allows movement of the mandrel such that the locking ball again locks the mandrel and adapter when the mandrel is moved to a sealed position wherein the inflatable packer element is sealingly closed. The inflatable packer of the present invention comprises a valve for opening a central passageway through the packer. A J-slot in the packer allows a plurality of inflation cycles to insure proper setting of the packer prior to actuation of the valve. The bridge plug of the present invention comprises a bypass passage therethrough which may be opened by upward movement of a central mandrel. A releasing tool is provided for releasing the packer or bridge plug in the well bore after setting of the packer element.

Abstract: A well tool having reciprocating portions can be locked in a predetermined position by a latching mechanism which is responsive to externally applied pressure, as opposed to mere movement of the reciprocating elements to the predetermined position. The actuating pressure can be applied through the annulus or through a pipe string in which the tool is located.
