Abstract: A device for terminating a hybrid electrical/fiber optic cable at a connector comprising a clamp assembly affecting a swage lock on a k-tube to prevent movement of the k-tube within the connector and resultant damage to the optical fibers. The clamp assembly comprises two clamp halves, at least one of which includes a k-tube groove, one or more optical fiber grooves, a fan out cavity, and means for joining the clamp halves. When the clamp halves are joined, the k-tube grooves form an enclosed k-tube channel that is slightly smaller than the outside diameter of the k-tube, thereby creating a swage lock to prevent movement of the k-tube. Similarly, the optical fiber grooves create a swage lock on protective plastic tubes that are placed over the optical fibers as they exit and fan out from the k-tube in the fan out cavity.

Abstract: A heat activated flue damper actuator employing an assembly of shape memory alloy springs with linkages to a conventionally designed contemporary flue damper. The combination of the spring material, spring configuration and dimensions, linkage/fastening scheme to the flue damper shaft and placement in the water heater's heating chamber are all controlled to optimize the energy efficiency of a conventionally designed, pilot-lit or pilotless ignition, contemporary gas water heater.
