IPC: G01N3/34
Filed: 2003-07-16
Abstract: A compressed symbology strain gage includes a target in the form of a symbolic strain rosette ("SSR"), the target being associated with a body for which strain is to be measured and being adapted to emit a detectable physical quantity; a sensor compatible with and adapted to pre-process the detectable physical quantity emitted by the target and output data representing the physical quantity adapted to receive signals from the target and provide output signals based thereon; a computer program or programs for analyzing the signals data output by the sensor to define the SSR; and for calculating the strain directly on the body based on the pre-processed and analyzed data. The SSR can be defined either a priori by manufacture or a posteriori by identification. A method of measuring strain on an object using the compressed symbology strain gage includes the steps of associating a SSR with an object in such a way that deformation of the SSR and deformation under load of the object bear a one-to-one relationship; identifying the changes in the SSR as a function of time and change in the load applied to the object; and translating the changes in the SSR into strain.

Title: Vehicular drive control device
Inventor: MATSUBARA TORU
IPC: F16H61/686
Filed: 2005-01-06
Abstract: <P>PROBLEM TO BE SOLVED: To prevent the occurrence of shock due to a rapid change of engine brake when performing down-shift with fuel-cut and slip control of a lock-up clutch during coast, and to prevent the restart of fuel supply resulting in worsened fuel consumption with an engine speed being lower than a F/C reset rotating speed.  <P>SOLUTION: When down-shift is performed during coast, before a inertial phase is started, the lock-up clutch is feedback controlled to achieve a preset target slip amount. This prevents the restart of fuel supply resulting in worsened fuel consumption with the slip amount being too much and the engine speed being lower than the F/C reset rotating speed. After the inertial phase is started, the feedback control is stopped. This prevents the occurrence of shifting shock due to a rapid change of the engine brake with a change in the rotating speed of a turbine.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
