A present dual-bearing reel spool braking device is configured to apply a braking force to a spool that is rotatably mounted on a reel body with a centrifugal force. The present invention provides a search engine and data management technology that can understand what users are looking for, understand the data in a database, and present immediately useful suggestions for finding the right information. The fire control system uses a CW two-tone monopulse radar to derive range and angle of arrival within 150 milliseconds, with range and angle of arrival measurements having approximately twice the accuracy of prior CW two-tone monopulse radars. The encasement together with the stiffener plate enlarges the dispenser to approximately the same outer diameter as the torpedo to which it is attached. The server may use the information to identify walkable paths within the indoor space. These compounds are particularly useful for the treatment of cancer.
