The invention provides a novel array method for nucleic acid sequence detection with improved specificity which allows for detection of genetic variation, from simple SNPs to more complex sequence variation patterns. The motion sensor detects general motion, movement, or acceleration of the device and outputs a series of momentary measurements. A distance between the top surface of the touch sheet and the top surface of the display stack is between about 225 and 1500 micrometers. The lower back plate is preferably positioned proximate the upper back plate when the basketball rim assembly is in the collapsed position and the lower back plate is spaced apart from the upper back plate when the basketball assembly is in the use position. The context manager accesses data stored on an instance level for a given sequence of operations within a given application domain. It is also possible to adjust the gain by an attenuator as required.
