Improved techniques and systems for utilizing a portable electronic device to monitor, process, present and manage data captured by a remote sensor during a physical activity session are disclosed. 5-methyl-pyridine-2-sulfonic acid 6-methoxy-5–2-pyridin-4-yl-pyrimidin-4-yl-amide also forms solvates with, for example, ethanol, acetone, tetrahydrofuran, methanol, isopropanol, 2-butanone and dichloromethane. The silicon substrate and the titanium film are reacted with each other by a first annealing process to form a titanium silicide film on the bottom surface. A flow of thermally treated air to the heat sink masses serves to regulate the temperature of the heat sink masses.
