Abstract: A system comprises an optical fiber, a manipulator assembly, and a control unit. The manipulator assembly comprises a chassis, an optical fiber cleaning assembly housed within the chassis, and a drive mechanism housed within the chassis. The optical fiber cleaning assembly comprises a cleaning tape, a first spool on which the cleaning tape is wound, and a second spool onto which the cleaning tape is drawn after use. The drive mechanism is configured to advance the cleaning tape from the first spool to the second spool such that a portion of the cleaning tape wipes a face of the optical fiber. The control unit is configured to control the drive mechanism to advance the cleaning tape.

Abstract: A fishing lure comprising a crankbait or similar body member to which both a spinner and a hook are attached, provides the crankbait with a realistic swimming motion. In particular, the spinning of the spinner, coupled with its positioning on the crankbait, imparts an oscillating, swimming-like motion to the crankbait, which greatly enhances the luring of fish. This is in addition to the benefits already derived by virtue of the spinning of the spinner.
