The present invention is directed to methods for detecting the presence of genetic polymorphisms that correlate with altered gene expression. In one embodiment, the method may control an amount of boost provided by a turbocharger to an engine. The camera housing includes a touch-through membrane in a position that allows the membrane to align with the touch-sensitive surface when the camera is placed in the housing. Location using SUPL over SIP may be provided about a caller making an E911 emergency call.
