Abstract: A scintillator crystal assembly includes a crystal array and an open reflective insert. The crystal array is configured to receive rays emitted by an object to be imaged and to emit light energy responsive to the received rays. The crystal array comprising plural crystals arranged in rows. Each crystal includes a reception surface configured to receive the rays emitted by the object to be imaged, an emission surface configured to emit the light energy responsive to the received rays, and plural sides extending from the emission surface that are aligned with sides of adjacent crystals in the crystal array. The open reflective insert is disposed between adjacent rows of the crystal array, and includes at least one reflective portion and at least one opening. The at least one reflective portion defines an area and the at least one opening is positioned within the area.

Abstract: A portable imaging detector and a method for operating the portable imaging detector are provided. The portable imaging detector includes a docking connector having a plurality of docking connector contacts. The method includes measuring a voltage at a first docking connector contact, and determining whether the portable detector is (i) operating in a digital cassette mode or is (ii) installed in either a cassette holder or a charging bin using the measured voltage. A detector state monitoring system is also discussed.

Abstract: A method for downward communication in a borehole containing a pipe string, comprising the steps of: imparting a series of rotary motions to an upper portion of the string, the rotary motions representing at least two levels of a coded data sequence, the rotary motions imparted to a string upper portion effecting generally comparable motions at a lower portion of the string; the motions at the string lower portion effecting a downhole detectable condition or conditions indicative of rotation or no-rotation; detecting the condition or conditions to determine a corresponding coded data sequence; and processing corresponding data sequence to recover the imparted coded data sequence, from which a unique transmitted message is determinable.
