Abstract: A system and related method for improving tire uniformity includes providing at least one set of test tires constructed with one or more process elements provided at known relative angular locations. At least one uniformity parameter, such as radial or lateral run-out, balance, mass variation, radial lateral or tangential force variation, is measured for at least one harmonic of interest for each test tire. Respective rectangular coordinates are determined for each measured uniformity parameter and harmonic of interest for each tire. A form of the determined rectangular coordinates (e.g., the rectangular coordinates themselves and/or the log of the residuals squared) is analyzed for each tire to identify optimized relative angular locations for each process element that reduce dispersion (or dispersion and mean) of the measured uniformity parameter. New tires are built with the one or more process elements positioned in the identified optimized relative angular locations.

Said pipecolic solid-phase linker may be used for coupling functional groups chosen between primary amines, secondary amines, aromatic amines, alcohols, phenols and thiols. In particular, said pipecolic solid-phase linker may be used for peptide or pseudopeptide synthesis, such as the reverse N to C peptide synthesis or the retro-inverso peptide synthesis, or for the synthesis of small organic molecules.

Abstract: Disclosed are apparatus and methodology for minimizing and compensating for cracking in piezoelectric devices so as to maintain long term functionality of the devices. Compensation for cracking is achieved by applying solid conductive electrodes over the entire surface of the piezoelectric device and extending the electrodes beyond the perimeter of the piezoelectric device. In this way electrical connections are maintained even in the presence of cracking. Cracking of the piezoelectric device is limited by minimizing the local bending moment of the piezoelectric device by way of applying insulative support materials that may vary in thickness.

Abstract: An electronic device with data stored therein is integrated into a tyre. The data is stored in a memory of the electronic device. The memory includes a data storage zone with a field reserved for a serial number of the tyre, which is stored in bit form. When the data stored in the field reserved for the serial number of the tyre is read, at least a part of the read data is decoded into at least one letter so as to determine the serial number of the tyre.

Abstract: Improved and more easily implemented methods for predicting uniformity parameters such as uneven mass distribution, radial run out and high speed radial force variation utilize other measurements such as the tire crown thickness variation. When high speed radial force variation is calculated, low speed radial force variation is also measured. Tire crown thickness variation can be measured in different fashions depending on the particular tire manufacturing process employed. By electronically determining resultant uniformity parameters, tires can be improved by rectification to address the uniformity levels. In addition, tire manufacturing can be improved by altering the resultant location of tire crown thickness variation relative to other aspects of the tire and/or tire manufacturing process.
