Abstract: The invention relates to a measuring method to determine elongation after fracture on a tensile testpiece in a computer controlled tensile test. To meet the requirements of the tensile test to DIN EN 10002/1, the measuring grid known from DIN EN 10002/1 is applied to the tensile testpiece. The measuring grid is scanned with a line sensing camera. In the tensile test the elongation of the testpiece is determined when the tensile force has exceeded its maximum and drops to zero. That place for which the computer with the CCD camera detects the greatest distance between adjacent grid lines is utilized to calculate the elongation after fracture to DIN EN 10002/1.

Abstract: A thin-film ROM devise comprises an array of open-circuit and closed-circuit cells (5 to 8) formed from a stack of thin films (12,21,22,23,11) on a glass or other substrate (10). The semiconductor films (21,22,23) may be of hydrogenated amorphous silicon.

In this way, at least a second type of thin-film diode (MIM, MIN, MIP) is formed having a different conduction characteristic to that of a first type (NIP), so increasing the information content of the ROM array. A lower semiconductor film (23) can be readily etched away from the lower electrode film (11) by a selective etching treatment in which the electrode film (11) acts as an etch stop. By monitoring emissions during plasma etching, an upper semiconductor film (21 or 22) can be removed from a lower semiconductor film (22 or 23).

Abstract: A method of imaging and quantitatively measuring blood velocity distribution within a selected vessel employs Nuclear Magnetic Resonance cylindrical excitation of the sample to be imaged, followed by Fourier velocity encoding excitation along a second axis for selectively encoding molecules based upon their flow velocities, then sensing the re-radiated signal data acquired in the presence of a readout gradient to provide resolution along the cylindrical axis, and reconstructing a velocity profile. Spatial localization is accomplished with an excitation pulse having a cylindrical rather than slab geometry. This method can be combined with cardiac synchronization to measure flow dynamics or it can be applied without synchronization to measure steady flow. The geometry of the measurement is flexible in that the directions of flow sensitivity and geometric resolution are independent.
