A guide clamp for clamping a femur and guiding placement of a guide wire relative to the femur. The guide clamp includes a body supporting a pair of clamping surfaces at the end of a pair of clamping arms that are spring-biased to move with respect to each other into a closed position to grip the femur. Defined by the body is a guide opening that guides insertion of the guide pin once the femur has been gripped. One of the clamping arms of the guide clamp may have proximal and distal portions that are slidably adjustable with respect to each other to allow a controlled repositioning of the guide opening with respect to the femur. The guide clamp may also include an engagement member which is supported by the body of the clamp and is capable of advancing into abutting contact with the head of the femur.

The present invention provides an occluder with a self centering system that keeps the occluder properly centered in a defect which allows the center of the occluder to remain properly positioned within the defect so that the left and right sides cover the entire defect which reduces the chance of blood shunting through the defect and increases the effectiveness of the occluder. The self centering system is comprised of a series of arms that provide tension to hold the right and left sides in place. The arms are shaped to provide a flexible intermediate zone comprising a left and a right conical shaped network, wherein each network extends from the right and left sides and narrows at the center section. The flexible intermediate zone centers the occluder and helps to hold it in place.

A video surveillance system includes multiple video cameras. The surveillance system is configured with an arrangement to separate the surveillance functions and assign different surveillance functions to different cameras. A master camera is assigned the surveillance of large area surveillance and tracking of object movement while one or more slave cameras are provided to dynamically rotate and adjust focus to obtain clear image of the moving objects as detected by the master camera. Algorithms to adjust the focus-of-attention are disclosed to effectively carry out the tasks by a slave camera under the command of a master camera to obtain images of a moving object with clear feature detections.

A flexible accommodating intraocular lens having anteriorly and posteriorly movable extended portions, such as T-shaped haptics, extending from a central solid biconvex optic to be implanted within a natural capsular bag of a human eye with the extended portions positioned between an anterior capsular rim and a posterior capsule of the bag, whereby during a post-operative healing period, fibrosis occurs about the extended portions to fixate the lens in the bag in a manner such that subsequent natural contraction and relaxation of the ciliary muscle moves and deforms the optic to provide vision accommodation.

Improved method and apparatus for interlocking hemmed together edges of inner and outer vehicle body panels with an improved interlock joint. The inner panel blank is draw stamped and provided with PLP holes in a stamping press. A plurality of conventional hardware components are then welded to the inner panel. Then interlock holes are formed by a piercing tool moving through the inner panel border from its outboard to its inboard side while the inner panel is held by clamps and PLP pins. The hole piercing punch thus leaves cold worked upset material slightly raised inboard, rather than outboard, around the pierced interlock hole margin. Then the inner panel subassembly is married to the outer panel and transferred to a hemming station and again precisely clamped and positioned by PLP pins, whereupon hemming press gates are operable for hemming the flange lip of the outer panel over the inner panel border. The final hemming steel of each gate carries staking punches that individually strike a precision registered portion of such hemmed lip to deform it into locking engagement with the associated interlock hole. The upset material is thus flattened and accurately worked into embedment into the interior surface of the hemmed flange lip, rather than into the interior surface of the outer panel, thereby avoiding creating read through problems on the outer panel.

A contact lens with a central region (10) that is optimally less than approximately 1.9 millimeters in diameter and that is preferably overcorrected by approximately 25% to 100% over the correction needed for reading. Unexpectedly, the central region (10) does not impair distance vision, but compensates for presbyopia and therefore alows a user to focus on objects within a range of near and intermediate distances. A method for fitting the contact lens is also provided.

An accommodating intraocular lens having anteriorly and posteriorly movable extended portions, such as T-shaped haptics, extending from a central optic to be implanted within a human eye, and a second optic spaced from the posterior optic. The first optic is intended to be implanted in the capsular bag, and the second optic may be located in the capsular bag, in the sulcus, or in the anterior chamber. The second optic can be spaced from and fixed to the first optic and this lens assembly implanted in the capsular bag.

A novel method and apparatus are provided for correcting an off-center laser ablation in the cornea, in which the original ablated area has a center that is offset from the correct center of the optical cornea. The method comprises the steps of determining the correct optical center of the cornea and the offset location of the ablation; performing a supplemental laser ablation on the cornea with the laser beam covering generally the original ablated area, and with the energy of the supplemental laser increasing in a direction from the offset center toward the correct center; introducing a laser shield to cover the entire original ablated area; and performing another laser ablation with the correct optical center as the center of the ablated area.

A device for properly positioning and constraining the grip of a golfer on a golf club handle and, particularly, for preventing the thumb from rotating to the right or to the left during the golf stroke.

A fish is scaled, and its internal organs removed, by continuously advancing the fish along a treatment path while simultaneously exposing the fish body to high-pressure water jets. During treatment the fish is positioned vertically, with the belly downwards. The forces required for holding and transporting the fish are applied laterally to the upper part of the fish body, which is harder, without touching the belly area, which is soft and therefore is left free. The descaled fish proceeds to a position for cutting the belly area and removing the internal organs. The treatment is carried out in the same devices efficiently and without deterioration of the gustatory properties.

The stator comprises a casing and at least one stage of variable-pitch stator vanes, said vanes being moved by an actuator ring outside said casing and carried thereby, and said ring being connected by links to the vanes in order to actuate them simultaneously, in which said casing includes a stationary coaxial rail projecting from the outside surface of the casing, and at least three circumferentially spaced-apart groups of wheels are constrained to move along said rail, each group of wheels being coupled to said ring by a radial guidance arrangement, each group of wheels comprising at least two wheels engaged with said rail, and each wheel being mounted to rotate on a radially-oriented pin, said pin being mounted directly on said ring.

The rotary housing of a hydrokinetic torque converter, which can be utilized in the power train of a motor vehicle-for example, in conjunction with a continuously variable transmission-contains a torque monitoring device which is installed in such a way that it does not take up any, or any appreciable, additional space, especially in the axial direction of the housing. The torque monitoring device can serve to transmit torque between the lockup clutch and the output element of the torque converter. Additional features reside in the provision, configuration and manner of mounting of an auxiliary mass, and in the provision of a device for centering the piston of the lockup clutch in the housing as well as a device for centering the housing on the output element of a prime mover.
