An articulating surgical instrument suited for endoscopic use includes a lateral articulation control into a handle portion that provides an intuitive visual and tactile indication to the clinician as to the amount and direction of articulation of an end effector at a distal end of a shaft. Lateral movement of a lateral control actuator is converted into a longitudinal motion or a rotational motion transferred by the shaft to an articulation mechanism. A version of a lateral articulation control for a rotationally driven articulation mechanism incorporates an articulation backdrive lockout that prevents forces on the end effector from causing the selected amount of articulation from being changed.

Embodiments relate to applying a magnetic field across the paths of injected polar precursor molecules to cause spiral movement of the precursor molecules relative to the surface of a substrate. When the polar precursor molecules arrive at the surface of the substrate, the polar precursor molecules make lateral movements on the surface due to their inertia. Such lateral movements of the polar precursor molecules increase the chance that the molecules would find and settle at sites (e.g., nucleation sites, broken bonds and stepped surface locations) or react on the surface of the substrate. Due to the increased chance of absorption or reaction of the polar precursor molecules, the injection time or injection iterations may be reduced.

Apparatus and method for selectively engaging and securing an array of shelf dividers to a mounting device which is securable to a display shelf. In the first form a divider is characterized by a divider structure having an elongated vertical wall and elongated horizontal base that operates to divide, organize and support the displayed merchandise. A resilient latch located on the underside of the base of the divider structure selectively engages and secures the divider structure onto a mounting device comprising a receiving member running longitudinally along the length of the surface of the mounting device which is securable along the front edge of a display shelf. The latch and the receiving member each comprise reciprocating (i.e. complementary) protrusions to allow the cooperative engagement of the divider structure and mounting device, thus locking the divider member to and unlocking the divider member from the mounting device to permit the repositioning of the display as desired without necessitating removal of the merchandise from the display. In addition when the divider structure and mounting device are fully engaged, a second protrusion on the underside of the divider member cooperates with a flange or lip on the mounting device to prevent lateral movement of the divider structure and maintain the position of the divider perpendicular to the mounting device and the front edge of the shelf. In a second embodiment, the divider structure comprises a pusher track and a spring urged pusher assembly to automatically push merchandise to the front of the shelf. Another embodiment comprises a divider base without a vertical divider wall, and with or without a pusher track and spring urged pusher assembly, thus pushers and dividers can be used in various convenient combinations within a shelf management system.

Disclosed is an ultrasonic surgical instrument that combines end-effector geometry to best affect the multiple functions of a shears-type configuration. The shape of the blade is characterized by a radiused cut offset by some distance to form a curved geometry. The cut creates a curved surface with multiple asymmetries causing multiple imbalances within the blade. Imbalance due to the curve of the instrument is corrected by a non-functional asymmetry proximal to the functional asymmetry. Imbalance due to the asymmetric cross-section of the blade is corrected by the appropriate selection of the volume and location of material removed from a functional asymmetry. The shape of the blade in one embodiment of the present invention is characterized by two radiused cuts offset by some distance to form a curved and potentially tapered geometry. These two cuts create curved surfaces including a concave surface and a convex surface. The length of the radiused cuts affects, in part, the acoustic balancing of the transverse motion induced by the curved shape.

Intrabuccal device includes two shells (2, 3) made of thermoformed plastic material, the first of which respectively covers the superior arch, and the second of which covers the inferior arch of the oral cavity. This device is provided with (rings and arms) (4a, 4b, 13a, 13b) that act on the said shells (2, 3) and can generate a mandibular propulsion force oriented in the direction of the mandibular propulsion and in the posteroanterior sense, so as to keep a shift of the mandible to the front of the maxilla, while allowing lateral movements.

The present invention relates to a propulsion system of a vertical takeoff and landing aircraft or vehicle moving in any fluid or vacuum and more particularly to a vector control system of the vehicle propulsion thrust allowing an independent displacement with six degrees of freedom, three degrees of translation in relation to its centre of mass and three degrees of rotation in relation to its centre of mass. The aircraft displacement ability using the propulsion system of the present invention depends on two main thrusters or propellers and which can be tilted around pitch is (I) by means of tilting mechanisms and, used to perform a forward or backward movement, can be tilted around roll axis (X) by means of tilting mechanisms and, used to perform lateral movements to the right or to the left and to perform upward or downward movements (Z), the main thrusters being further used to perform rotations around the vehicle yaw axis (Z) and around the roll is (X). The locomotion function also uses one or two auxiliary thrusters or propellers and mainly used to control the rotation around the pitch axis, these thrusters or propellers and being fixed at or near the longitudinal is of the vehicle, with there thrust perpendicular or nearly perpendicular to the roll and pitch axis of the vehicle.

Mechanisms for a control knob or other interface device providing additional degrees of freedom for the knob. One embodiment provides a rotatable knob moveable also in a lateral plane approximately perpendicular to the axis of rotation. A mechanism providing the lateral motion can include a gate member and a plunger member that engages grooves in the gate member. A rotational sensor detects a rotational position and a lateral sensor can detect a lateral position of the knob. Another embodiment provides an actuator that includes a shaft that is coaxial with the axis of rotation and which can be moved linearly along the axis of rotation with respect to actuator housing to accommodate linear motion of the knob. In another embodiment, a gear assembly including two interlocked gears is provided to transmit rotational motion from the knob to the sensor, and the interlocked gears translate with respect to each other when the knob is translated along the rotational axis.

In an endoprosthesis (11h) for a joint, the two interacting joint parts (15h, 16h) are joined by a cord-type connection piece (21h), which is attached in the vicinity of the body axis (M2h, M2h') of the convex condyle (15h) and extends through a longitudinal groove (22h) in the flexion direction of the joint. The connection piece assures a play space (31h) between the contact surfaces (19h, h', 20h, h') of joint (11h). It is protected from friction on groove wall (55h, 55h') by an elevation (50h, 43h) in concave joint part (16h). An elevation (43h, 50h) at concave joint part (16h) and a depression (49h) at convex joint part (15h) interact in such a way that the lateral movement play space between depression and elevation determines the freedom of movement with respect to the lateroflexion of the joint. In preferred forms of embodiment, thanks to the spherical surfaces at least one pair of corresponding sliding surfaces (19h, 20h; 20h') on the two condyles lie flatly on one another, under load, in any position of the joint.
