Abstract: Systems and methods are provided for prepare list communication to participants in a two-phase commit protocol transaction processing. An exemplary method includes receiving a distributed transaction for processing, wherein the processing uses a two-phase commit protocol, receiving a distributed transaction comprising a plurality of processes for processing, wherein the processing uses a two-phase commit protocol and preparing, by a main coordinator, at least one participating processing node from the plurality of processes, wherein the at least one participating processing node comprises a first sub-coordinator and a first participant, and wherein the first participant executes a first process of the plurality of processes. The method further includes receiving, by the main coordinator, a first list comprising the first participant registered with the first sub-coordinator.

Abstract: A head restraint assembly for a vehicle seat includes a base portion, a head restraint, and a locking mechanism. The head restraint is mounted with respect to the base portion and is selectively rotatable with respect to the base portion about a first axis. The locking mechanism includes a first lock member, a second lock member, and a first spring. The first lock member is mounted with respect to the base portion and defines a first plurality of teeth. The second lock member is movably mounted with respect to the head restraint and the first lock member. The second lock member defines a second plurality of teeth. The first spring continuously biases the second lock member toward the first lock member such that the second plurality of teeth continuously contact the first plurality of teeth.

Abstract: A ratcheting pivot mechanism for coupling a head rest portion of a vehicle head restraint assembly to a post portion of a vehicle head restraint assembly includes a first pivot arm, a second pivot arm pivotably connected to the first pivot arm, a movable ratchet member pivotably connected to the second pivot arm, and a spring disposed between the second pivot arm and the movable ratchet member. The first pivot arm has a fixed ratchet member, which the movable ratchet member is configured to selectively engage. The spring is configured to apply an engaging force to the movable ratchet member when the movable ratchet member is in a first position, and configured to apply a disengaging force to the movable ratchet member when the movable ratchet member is in a second position.

Abstract: Disclosed below are representative embodiments of methods, apparatus, and systems for managing and classifying assets in an information technology (“IT”) environment using a tag-based approach. The disclosed tag-based classification techniques can be implemented through a graphical user interface. Embodiments of the disclosed tag-based classification techniques can be used to allow a user to easily and quickly select and perform actions on groups of one or more assets (e.g., monitor policies, perform upgrades, etc.). For example, the tag-based classification techniques can automatically classify assets into “tag sets” (or “tagged sets”) based on node properties or user-selected criteria or conditions (e.g., criteria or conditions that are established in a user-created tagging profile or rule). The tagged assets can then be further filtered to identify even deeper relationships between the assets.

Abstract: A foldable seat headrest assembly including a locking mechanism that includes a lock lever that can be manipulated by a manual release handle that selectively locks the headrest pad component against a groove formed in a portion of a lock post so as to keep the headrest assembly in an upright position. The groove provides both a back stop and a forward stop for the lock lever. When the lock lever is disengaged from the groove by manipulating the release handle in a downward motion, a dump spring allows the headrest portion to assume a folded or dumped position. In the folded or dumped position, the headrest portion fits compactly against the back portion of the seat. The manual release handle can be associated with either the left or the right side of the headrest assembly allowing the same assembly to be used on either side of a vehicle, e.g., the driver or passenger side of the vehicle, as well in the front and rear seats.

Abstract: Improved apparatus, systems, and methods for inspecting a structure are provided that use a probe having two ultrasonic transducer arrays. This enables simultaneous testing using two different test frequencies. The probe uses pulse echo ultrasonic signals at different frequencies to inspect the structure. The probe includes a support body having a fluid conduit formed therein. The fluid conduit provides flow paths for a couplant (such as water) that is used to couple the ultrasonic signals between the structure under test and the arrays. The fluid conduit is configured to quickly eject couplant and bubbles contained in the couplant.

Abstract: Improved apparatus, systems, and methods for inspecting a structure are provided that use a pedestal robot mounted on a rail system, a probe extension coupler, and an inspection probe capable of performing pulse echo ultrasonic inspection. A probe may also include sled appendages and an axial braking system to inspect over holes and off edges. A probe may also include an ultrasonic pulse echo transducer array for high rate inspection; the transducer array may be mounted in a bubbler shoe for individually coupling each of the transducers in the array. A rail system may also include an optical encoder for providing location information for the robot and axial braking system. A probe extension coupler presses the inspection probe against the structure for adjusting to changes in surface contours.

Abstract: Improved apparatus, systems, and methods for inspecting a structure are provided that use a probe with sled appendages and an axial braking system. The probe uses pulse echo ultrasonic signals to inspect the structure. The sled appendages permit the probe to contact and ride along the surface of the structure and are rotatably connected and curved away from the surface of the structure to compensate for contoured surfaces and inspection around holes and edges. The axial braking system, in coordination with a motion control system moving the probe, fixes the positions of the sled appendages just before the probe travels over a hole or off an edge of the structure to prevent the probe from falling through the hole or off an edge and to permit the probe to return to the surface of the structure to continue inspection of the structure.

Abstract: A pontoon boat having a support framework that includes a number of telescoping cross members that laterally extend and retract to vary the width of the craft. Included tires rotate into and out of ground contact to permit towing without the need for a separate trailer. A motor or hand crank controls a longitudinal lead screw mounted to a reciprocating trailer tongue. Lateral control arms pivot with motion of the tongue member and laterally displace longitudinal side rails and flotation pontoons. A deck and handrails are raised and lowered as the framework reciprocates between travel and flotation positions. One of the sets of telescoping cross members separately rotates the tire support assemblies. A deck control assembly controls the alignment and separation of the deck at a longitudinal seam.
