A tape drive is provided having a pair of stationary guide assemblies disposed symmetrically about the magnetic readwrite head. One method involves determining a brightness value of at least one pixel of each bi-directionally predicted intermediate frame in the sequence as an equal average of brightness values of pixels in non-bidirectionally predicted frames bracketing the sequence of bi-directionally predicted intermediate frames. In one embodiment, a server receives a request for an application from the wireless device, enables the application, and tracks the time for which the application is enabled. The dual load path structure has dual wing skin plates and a rotation joint coupled between the dual wing skin plates and configured to rotationally couple the unfixed wing tip portion to the fixed wing portion. To release the buoyant body, a trigger mechanism provided at the closed loop member is operated to fusion cut the closed loop member.
