Abstract: The present invention relates to a backpack system for transporting items and an accompanying device. In exemplary embodiments, carried items are kept secure within a plurality of item holders to prevent the items from moving. The item holders can be rigid structures like cylinders or flexible canvas pouches. In exemplary embodiments, the backpack system can have configurations for carrying either a device or additional items.

Abstract: A server receives a first set of file activity data from a first file monitor. The first set of file activity data indicates activity associated with a first set of files accessed at a first compute node in communication with a network. Further, the server receives a second set of file activity data from a second file monitor. The second set of file activity data indicates activity associated with a second set of files accessed at a second compute node in communication with the network. In addition, the server aggregates the first set of file activity data and the second set of file activity data into an aggregated set of network file activity data.

Abstract: An optical device may include at least one optical element and a coupling section adapted to control relative movement between the at least one optical element and the coupling section. The coupling section may include an engaging element and a detent mechanism adapted to adjustably lock the at least one optical element in a plurality of rotational positions. The rotational positions may include rotational positions around a first axis that is substantially perpendicular to a second axis of the at least one optical element, the second axis being a substantially longitudinal axis of the at least one optical element.
