    摘要: A joint spacer for therapeutically maintains separation of bones of a joint. A frame defines a longitudinal axis extending between distal and proximal ends. A carriage is slideably retained within the frame and has at least one ramped surface and a threaded portion. An actuator screw is threadably engaged with the threaded portion, and bears against said frame to cause the carriage to slideably move within the frame when the actuator screw is rotated. A first endplate engages a bone of the joint, and has at least one ramped surface that is mateable with the ramped surface of the carriage.

    摘要: The present invention is directed to child safety seats, and more particularly to a harness or belt tensioning indicator for a child safety seat harness system. The tension indicator includes a body portion for receiving a belt, harness or webbing. The tension indicator also includes a sliding indicator that is capable of moving from a first, unactuated position to a second, actuated position when the belt, harness or webbing that is received in the body portion is tensioned from a first tension to a second, correct tension.
