SBL systems use this concept to an advantage by adjusting transducer spacing for best results [4] When operating from larger ships, from docks or from the sea ice where greater transducer spacing can be used, SBL systems can yield a positioning accuracy and robustness approaching that of sea-floor mounted LBL systems.
Tracking packages with stationary bar code reader in a warehouse sorting operation. Package tracking or package logging is the process of localizing shipping containers, mail and parcel post at different points of time during sorting, warehousing, and package delivery to verify their provenance and to predict and aid delivery.
Water surface searches are procedures carried out on or over the surface of a body of water with the purpose of finding lost vessels, persons, or floating objects, which may use one or more of a variety of search patterns depending on the target of the search, as the direction and rate of drift vary depending on the characteristics of the target and the water and weather conditions at the time.
The search and inspection of the lost nuclear submarine USS Thresher by the U.S. Navy oceanographic vessel USNS Mizar in 1963 is frequently credited as the origin of modern underwater acoustic navigation systems. [7] Mizar primarily used a short baseline (SBL) system to track the bathyscaphe Trieste 1. However, its capability also included ...
Ocean tracers are used to deduce small scale flow patterns, large-scale ocean circulation, water mass formation and changes, "dating" of water masses, and carbon dioxide storage and uptake. [2] [3] Temperature, salinity, density, and other conservative tracers are often used to track currents, circulation and water mass mixing. [4]
An acoustic short baseline (SBL) positioning system was installed on the oceanographic vessel USNS Mizar. This system was used to guide the bathyscaphe Trieste 1 to the wreck site. Yet, the state of the technology was still so poor that out of ten search dives by Trieste 1, visual contact was only made once with the wreckage. [17]
Vessel Monitoring Systems (VMS) is a general term to describe systems that are used in commercial fishing to allow environmental and fisheries regulatory organizations to track and monitor the activities of fishing vessels. They are a key part of monitoring control and surveillance (MCS) programs at
Connections to the sewers (underground pipes, or aboveground ditches in some developing countries) are generally found downstream of the water consumers, but the sewer system is considered to be a separate system, rather than part of the water supply system. Water supply networks are often run by public utilities of the water industry.
