An on-chip navigation system, optionally combined with GPS andor an imaging array, which incorporates MEMS components is possible by the use of careful material selection and novel bonding techniques used during fabrication. In one embodiment, invalid memory references are identified as they occur. The remote interface manager provides a display of an application user interface to the mobile device, from which a user may access various applications that may be configured to execute at a remote device rather than on the mobile device. Each tilt sensor senses tilt of its location with respect to gravity, and the difference in tilt indicates air bag height. Specifically, this invention relates to a method and apparatus for obtaining increased cellular or particulate concentrations within the use of said optical scanning method. The present invention is also a method for inducing apoptosis in breast cancer cells by inhibiting the expression or activity of Spot 14.
