Abstract: A safety guard assembly for enclosing a flexible drive extending between a driving shaft and a driven shaft is provided. The safety guard assembly includes: a back cover having at least two slidably engageable back cover members for varying a length of the back cover, the back cover having at least two shaft openings extending therethrough for receiving a respective one of the driving shaft and the driven shaft therein; and a front cover having at least two slidably engageable front cover members for varying a length of the front cover, the front cover being securable to the back cover for defining an enclosure for the flexible drive. A method for enclosing a transmission mechanism including a flexible drive extending between a driving shaft and a driven shaft is also provided.

Abstract: Systems for controlling flow effector control surfaces. The system comprises a flow effector control coupled to an elongated bar at one end of the bar. The elongated bar is coupled at the other end to the middle of a T-shaped member. A compliant link is coupled to the bar between the control surface and the T-shaped member. At each end of the T-shaped member is coupled a shape memory alloy wire which acts as an actuating means. When one of the shape memory alloy wire contracts, the elongated bar pivots about the compliant link and activates or retracts the flow effector control surface.
