An improved stent design and stent delivery catheter assembly for repairing a main vessel and a side branch vessel forming a bifurcation. The stent includes rings aligned along a common longitudinal axis and connected by links, where the stent has one or more portals for aligning with and partially expanding into the opening to the side branch vessel. The stent is implanted at a bifurcation so that the main stent section is in the main vessel, and the portal section covers at least a portion of the opening to the side branch vessel. A second stent can be implanted in the side branch vessel and abut the expanded central section to provide full coverage of the bifurcated area in the main vessel and the side branch vessel. Radiopaque markers on the stent and on the tip of the delivery catheter assist in aligning the portal section with the opening to the side branch vessel.

A method of performing friction stir welding is provided herein. More specifically, traditional friction stir welding requires a rotatable head that is forced against a plurality of work pieces to bond the same. The rotational and normal forces generated by the friction stir welding tool are generally reacted by a backing plate, anvil, mandrel or other mechanisms, such hardware are subject to the applied forces and are often supported with additional internal supports. Conversely, a method of performing a friction stir weld is described that omits the need for such a backing member and internal supports as it is performed using a self reacting pin tool.

A gate wire including a gate line extending in the horizontal direction, and a gate electrode is formed on an insulating substrate. A gate insulating layer is formed on the gate wire and covers the same. A semiconductor pattern is formed on the gate insulating layer 30, and formed on the semiconductor pattern are a data wire having a date line in the vertical direction, a source electrode, a drain electrode separated from the source electrode opposite the source electrode with respect to the gate electrode, and an align pattern located on both sides of the data line. A passivation layer is formed on the data wire and the align pattern, and has contact holes exposing the drain electrode and an opening exposing the substrate between the data line and the align pattern. Here, the align pattern adjacent to the data line is exposed through the opening, and the semiconductor pattern and the gate insulating layer are under-cut. A pixel electrode connected to the drain electrode through the contact hole is formed on the passivation layer. Here, the opening is located between the data line and the pixel electrode. In this structure, misalignment occurring in the manufacturing process of a thin film transistor panel for a liquid crystal display is minimized, and stitch defects are prevented by uniformity forming a coupling capacitance between the data line and the pixel electrode. Shorts between the data line and the pixel electrode are prevented by forming the opening between the data line and the pixel electrode.

At a back side of the intrinsic amorphous silicon layer, an emitter layer and a base layer are provided. Interposed between these emitter and base layers is a separation layer comprising an electrically insulating material. This separation layer as well as the base layer and emitter layer may be generated by vapour deposition. Due to such processing, adjacent regions of the emitter layer and the separating layer and adjacent regions of the base layer and the separating layer partially laterally overlap in overlapping areas in such a way that at least a part of the separating layer is located closer to the substrate than an overlapping portion of the respective one of the emitter layer and the base layer.

A vehicle of the present disclosure may include at least one pair of opposing wheels coupled to a tiltable central chassis by a four-bar linkage or the like, such that the wheels are configured to tilt in unison with the central chassis. A steering actuator and/or a tilting actuator may be discretely controllable by an electronic controller of the vehicle. The controller may include processing logic configured to maintain alignment between a median plane of the chassis and a net force vector caused by gravity and any induced centrifugal forces. Various control algorithms may be utilized to steer the vehicle along a desired path, either autonomously or semi-autonomously.

A method for wafer bonding includes measuring grid distortion for a mated pairing of wafers to be bonded to determine if misalignment exists between the wafers. During processing of subsequent wafers, magnification of one or more lithographic patterns is adjusted to account for the misalignment. The subsequent wafers are bonded with reduced misalignment.

A wire stripper has a blade handle, a gripper handle, a blade jaw and a gripper jaw all pivotally connected at a main pivot pin that is offset from the mating faces of the jaws. Movable and floating cutting blades mounted on the blade jaw are self-aligning due to a floating connection of the blades that allows them to move respective gauge surfaces into engagement during closing. A blade hold down spring urges the blades into alignment. The jaws are angled with respect to the handle axis so the throat of the cutting blades aligns with a user's line of sight. Individual handle springs have differential springs rates and are arranged so that the handles springs do no resist opening of the jaws.

Aspects are provided allowing for selective monitoring of uplink cancellation indication (ULCI) occasions by UEs and allowing UEs to determine from ULCI whether canceled uplink transmission are carried on non-supplementary uplink (NUL) carriers or supplementary uplink (SUL) carriers. A UE may determine not to monitor a ULCI occasion if it does not have an uplink transmission which can be punctured by higher priority data. When the uplink transmission is dynamically scheduled, the UE may determine to monitor a ULCI occasion if the UE receives the uplink grant a certain number of symbols earlier than the ULCI occasion. The base station may configure blocks in downlink control information to indicate the UE should apply ULCI to SUL and/or NUL. The base station may configure the UE to perform different behaviors after receiving a ULCI depending on whether the portion of the uplink transmission to be canceled is on SUL or NUL.
