A method, having application to petroleum exploration or production, for picking the arrival time of seismic waves and use thereof for orienting the components of a multi-component sensor. An exemplary structure includes a multiplexer driving a memory element. Next, the system receives an execution environment change notification from a user of the application, and in response to the notification transitions the application to a second execution environment without interrupting the execution of the application. Additionally, the invention also provides devices that have standoff portions and voids that can reduce cross talk. Alternatively, two coating compositions can be disposed on a substrate where the material of the first coating composition is not substantially soluble in the second coating composition. A majority of the layers of the biaxial reflective polarizer having a smaller optical thickness are disposed closer to the display panel than the layers having a larger optical thickness.
