    Abstract: A closure mechanism for use in securing the ends as well as other portions of a pair of interlocking straps, laces, filaments and the like is disclosed. In one embodiment, the closure mechanism is in the form of a generally cylindrical enclosure having a cross-sectional shape which includes flat upper and lower surfaces with semi-circular ends. The closure mechanism may be used to secure a pair of thin planar, elongated strips, each of which has a plurality of ribs positioned transversely along the length thereof. Each of such ribs has a planar side face positioned at an angle of about 45 to 75 degrees relative to the plane of the upper surface of the planar strip to which it is attached. For optimal ease of engagement of the ribs of one strip with those of a second strip, the rear top surfaces of the ribs should be rounded or slightly relieved. The closure device of the present invention provides a high strength mechanism having a quick release feature for easy disengagement of the interlocking members.

    Abstract: A controllably variable optical fiber attenuator comprises a housing (100) and a pair of optical connector assemblies (300, 400) in which at least one of the optical connector assemblies includes an optical fiber termination element, such as a ferrule (350, 450), that is movable toward and away from the optical termination element of the other connector assembly to vary the length of the optical path between fiber termination elements. The movable element is carried by a carriage that is guided by the inner surfaces of the housing (100) and a guide pin slidably received in a bore of the carriage. A motor (210) drives a threaded shaft that engages mating threads in a bore of the carriage to effect linear movement of the carriage. An anti-lash spring is used with the carriage and motor shaft to enhance accuracy of movement. The motor (210) is preferably servo-controlled.
