Abstract: An external fixation system for treatment of bones includes first and second clamps for locking pins that are inserted into bones. At least one clamp includes a socket having a recess. An attachment post includes a distal portion configured to be inserted into the socket recess. A tightening nut is rotationally coupled to a shaft of the attachment post and has an internal threading adapted to be threaded to the external threading of the socket. When the tightening nut is rotated to cause the distal portion of the post to be further inserted into the recess, the sides of the distal portion of the post create an interference fit with the sides of the socket recess to lock the post to the first clamp.

Abstract: A pressure/force sensor comprises a diaphragm structure including a sensing element and a lead structure extending from the diaphragm structure and including first and second traces electrically coupled to the sensing element. The diaphragm structure and the lead structure include a circuit assembly comprising a common insulating layer and a common conductor layer on the insulating layer. The conductor layer includes at least a portion of the sensing element and at least the first trace.

Abstract: A movable waterfowl decoy includes: (a) a decoy body portion including a buoyant decoy body and a head portion attached to an upper front portion of the decoy body, the buoyant decoy body including at least one body compartment, the body compartment including at least one closeable compartment opening; (b) a power source housed in the at least one body compartment; (c) a spray propulsion system that is substantially housed within the at least one body compartment; (d) a keel attached to a lower surface of the buoyant decoy body; and (e) a remote control system, a remote receiver of which is within the at least one body compartment; wherein the decoy body portion emits an above-water spray of water from a body of water in a generally rearward direction when the waterfowl decoy is in use, which propels the decoy body portion in the body of water.
