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 training device for using chopsticks has a pair of parallel, spaced apart plates supported at the edges of the plates by a U-shaped spacer. Two L-shaped members are arranged in a back-to-back configuration and are attached at an edge of the plates, extending into the area between the two plates. The two upright portions of the L-shaped members are flexible and are shaped to support a chopstick. A flexible arm extends from the open end of the U-shaped spacer at an angle toward each upright portion. Once two chopsticks are inserted, the arm holds the chopsticks against the upright portion. Pressure against the edges of the chopsticks causes the arm and upright portion to flex and the tips of the chopsticks to be brought together. A number of features can be included, such as attaching a magnet or suction cup to one plate, printing one plate, or attaching a ring to the edge of the device to act as a key ring. In an alternate embodiment, the holder is associated with collapsible chopsticks.
