A method and a system for communicating data packets over a data bus is provided. The electronic unit includes a power source, an activation circuit which is a low powered activation circuit, and an operator. In embodiments, the vibratory gyro includes a plurality of multi-layer sub-wavelength gratings and a plurality of drive electrodes to measure motion of the proof mass induced by drive forces andor moments and induced by the Coriolis Effect when the gyro experiences a rotation. The operations are executed on the NAS device to produce a result that is stored in a second file in a location in a file system managed by the NAS device and accessible to the application server. If the identified boundaries do not possess the identified characteristics, then additional processing is performed to identify other locations, temporally near the identified boundaries, which correspond with boundaries of the portion of the audiovideo stream identified by the autonomous location information.
