A method, an apparatus and a computer readable medium for generating an image of a subsurface based on seismic data corresponding to at least two different times, for a same surveyed area are provided. The system comprises storage and a data protection component that includes an application programming interface defining a command set. The first port may be configured to introduce light into the optical circulator. Alternatively, an idle display component may be passed to a separate application and may be reclaimed by a requiring application when the idle display component becomes active again. In various applications the control expands to display options for adjusting at least one parameter for at least one device. Each load sensor comprises a cantilever-type sensor plate which is deformable when subjected to load, and a plurality of strain gauges attached to one surface of the sensor plate.
