A system for determining airtime of a moving sportsman includes at least one accelerometer for detecting vibration or acceleration of the sportsman. A first epitaxial layer is formed through the first component region. A second internal refrigerant circuit exists in the heat exchanger and operates when the first refrigerant circuit is at a standstill. A slide is mounted to the socket body to move horizontally. A gate electrode includes the planar silicon-based gate dielectric, the planar high-k gate dielectric, and a U-shaped high-k gate dielectric, and another gate electrode includes the chemical oxide portion and another U-shaped high-k gate dielectric. The memory cell of the present invention comprises a substrate, an overlying ferroelectric layer, which may comprise a film of rare earth manganite, and an interfacial oxide layer intermediate the substrate and the ferroelectric layer.
