Title: Laminography system for inspection of electronic connection and automatic warp compensation
Inventor: ADAMS JOHN A
IPC: G01N23/04
Filed: 1997-06-02
Abstract: The inspection system has a source of X-rays which emits X-rays through an electrical connection from a number of positions. An X-ray detector system is positioned to receive the X-rays produced by the source of X-rays which have penetrated the electrical connection. The X-ray detector system also has an output which emits data signals corresponding to an X-ray image of the electrical connection produced by the X-rays received and detected by the X-ray detector system after penetrating the electrical connection.  An analysis system has an image memory which stores the detector data signals, so forming an image database which contains information sufficient to form a cross-sectional image of a cutting plane of the electrical connection. An image processor searches the image database for a specific pre-determined feature located at a first Z-axis level in the electrical connection and combines the detector data signals with reference to the first Z-axis level to form a specific Z-level image database which contains information sufficient to form a cross-sectional image of a cutting plane of the electrical connection at a second Z-axis level in the electrical connection.

Patent DE-19754439-A1 (DE)
Title: Torque measurement arrangement for combustion engine
Inventor: OKAMOTO AKIO
IPC: G01L23/10
Filed: 1997-12-08
Abstract: The arrangement includes a combustion pressure sensor (13) which records an internal pressure of a combustion chamber (5). A memory unit (28) stores the internal pressure of the combustion chamber which has been recorded for each crank shaft angle. A current torque is calculated from a combustion pressure/crank shaft conversion coefficient with the crank angle as a parameter, and the pressure which was recorded during the combustion lift for each of a number of crank shaft angles. A torque is calculated through adding a number of the current torques which have been calculated for each combustion cycle. A torque change amount is calculated from the present combustion cycle and a combustion cycle of a predetermined number of cycles which precede the present combustion cycle. The internal pressure of the combustion chamber is recorded after the combustion, if no heat effects the combustion pressure sensor. The calculated torque is corrected through the recorded pressure and the combustion pressure/crank shaft conversion coefficient, according to the crank shaft angle at the point in time of the detection, whereby a torque change amount is calculated based on the corrected torque.
