IPC: A61B6/03

Abstract: A technique for detecting the spatial distribution of propagating energy induces secondary energy produced in a detector to drift in a predetermined direction at a predetermined velocity and synchronously moves the detector in a direction opposite to the direction of drift of the secondary energy at a velocity equal in magnitude to the magnitude of the velocity of drift of the secondary energy. Although the secondary energy is drifting with respect to the detector, the synchronous detector movement causes the secondary energy to appear stationary with respect to a source of radiation, resulting in "kinestatis" of the secondary energy. The secondary energy resulting from the radiation integrates along stationary paths in the detector (operated as a "kinestatic detector") and is subsequently detected when a collection volume of the detector sweeps through the stationary secondary energy. Signal integration can occur over long periods of time while resolution in the direction of movement of the detector is determined by the detector output sampling rate. A detector having n-by-I detecting elements can simulate the operation of any n-by-m element detector for use in digital radiography and computed tomography and other imaging and non-imaging sensing techniques. The detector may take the form of a xenon gas ionization chamber. Field distortion eliminating techniques are used to eliminate variations in charge carrier drift velocity in such an ionization chamber. Charge carrier mobility and drift velocity are adjusted to synchronize charge carrier movement with detector movement.

Abstract: A bifolded mailer is provided with head and foot panels (44, 50) which are individually shorter than its middle panel (46) but collec­tively longer than its middle panel. The middle panel is provided with a window flap (56) which remains joined along its lower margin. For variably printing the mailer on one face, the window flap is first folded down so that its outer face is exposed on the inner face of the mailer. After variable printing is applied, the form is processed foot first, in the course of which the window flap is folded back up and patched in place, the head panel is folded up and an insert body (80) is deposited in the resulting trough, the foot panel is folded down, and adhesive bands, which have been applied to various marginal regions of the mailer panels, are activated, for instance by heated platens, creating seals at the left and right ends and in the lap between the head and foot on the outside rear of the mailer. Opening the mailer is accomplished by tearing off marginal strips at the ends, and by pulling across another tear strip located in an external panel.
