Abstract: A dynamic rod implantable into a patient and connectable between two vertebral anchors in adjacent vertebral bodies is provided. The dynamic rod fixes the vertebral bodies together in a dynamic fashion providing immediate postoperative stability and support of the spine.  The dynamic rod comprises a first rod portion and a second rod portion connected together. The dynamic rod further includes at least a one bias element configured to provide a bias force in response to deflection or translation of the first rod portion relative to the second rod portion. The dynamic rod includes a locking construct which advantageously enables the extension and/or angulation of one rod portion with respect to the other rod portion to be reversibly locked in position. The dynamic rod permits relative movement of the first and second rod portions allowing the rod to carry some of the natural flexion and extension moments of the spine.

Title: Blower/vacuum tube attachment
Inventor: ROBISON BRET
IPC: A47L9/24
Filed: 2009-07-29
Abstract: A blower/vacuum device has removable blower tube configured to connect with a connector stub of the de-vice. The connector stub has a guide path formed in its interior wall and the blower tube has a latch runner disposed on its out-er surface. A flipper is positioned in the guide path near the end of the circumferen-tial segment of the guide path and coacts with the latch runner. The flipper is biased such that its tongue extends into the guide path. When the blower tube is rotated a sufficient distance such that the latch run-ner is rotated past the tongue, the flipper is repositioned by spring force and the tongue locks the blower tube in place. The flipper is repositioned to move the tongue out of contact with the latch runner to permit the blower tube to be rotated in the disconnect direction and removed from the connecting stub.

Title: Tire metallic cable anomaly detection method and apparatus
Inventor: BRANDON LEE
IPC: G01M17/02
Filed: 2010-03-31
Abstract: Disclosed is an apparatus and methodology for detecting anomalies in cables within a tire structure. A  plurality of magnetic field sensitive sensors are aligned within a magnetic field provided by a magnet. The align-ment of sensors and magnet is such that flux lines from the magnet are generally parallel to the plane occupied by the magnetic sensors. A tire cable anomaly present between the magnetic field sensitive sensors produces a detectable dif-ference in signals produced by the magnetic field sensitive sensors as a result of the formation of perpendicular flux patterns produced by the anomaly. A signal processing cir-cuit receiving input signals from the sensors evaluates dif-ferences between the signals from each of the plurality of sensors by pairing the output signal from each sensor with the output signal from each of the others of the plurality of sensors and produces an output signal upon the differences meeting selected criteria. The output signal may include an externally measurable signal and/or may include a visual signal indicating presence of a tire anomaly.

Abstract: A double shoulder drill stem connection for high torque applications includes a thread taper within a range between about 1.0 and 1.2 inch per foot.  The thread form is characterized by a stab angle between about 35 and 42 degrees and a load angle between about 25 and 34 degrees and by a short thread height with elliptical roots and with crests having an angle which slopes in an opposite direction with respect to the joint centerline from the thread taper. A drill string includes a tool joint having different inner diameters for a substantial axial length to provide enhanced strength in the threaded portion of the joint. The drill stem connection provides enhanced yield torque characteristics and allows for higher surface make-up torques than with conventional API tool joints because of the double shoulder connection in cooperation with the thread characteristics.
