An articulation mechanism is positioned between the support shaft and the end effector permitting selective movement of the end effector relative to the support shaft.

An adapter allows the interconnection of a sensor originating from one manufacturer to be coupled with conventionally incompatible monitors originating from other manufacturers to form a properly functioning pulse oximetry system. The adapter matches a sensor driver in a monitor to the current requirements and light source configuration of a sensor. The adapter also matches a sensor's light detector signal level to the dynamic range requirements of a monitor preamplifier. Further, the adapter provides compatible sensor calibration, sensor type and security information to a monitor. The adapter may have a self-contained power source or it may derive power from the monitor, allowing both passive and active adapter components. The adapter is particular suited as an adapter cable, replacing a conventional patient cable or sensor cable as the interconnection between a sensor to a monitor in a pulse oximetry system.

A handheld surgical device includes a multi-position throttle, rotatably attached to the body of the device, to allow for ambidextrous positioning of a motor speed control lever. The motor speed control lever may interact with a speed control sensor in the body of the device capable of detecting the actuation level of the motor speed control lever in any one of two or more positions.

A nut includes an internal thread and at least two parts, each of the parts having a section of the internal thread which can be pushed onto an external thread in the radial direction. The parts may have connecting elements which interact and permit a relative displacement of the parts in a direction running radially to the axis of the internal thread into a position of use. The connecting elements may have guide surfaces which are inclined at an angle to the plane running radially to the axis of the internal thread and guide the parts in a rotational movement about an axis of rotation running transversely to the axis. A part may have a locking arm with a guide surface only on one side which produces the rotational movement during the displacement of the parts and bears against a complementary guide surface of the other part.

A cam-actuated connection device joins rail mounting members of a photovoltaic panel array. The connection device slides within channels of mounting members until the members are in a properly positioned grid. When in position, the connection device is rotated to lock the mounting members in a rigid grid network. The connecting device can be subsequently loosened, repositioned and locked into position. The rail-mounting members create a grid for installation of multiple PV panels. The mounting rail allows the unit to remain relatively compact in nature but still covers a wide range of PV panel thicknesses. The rail system has a hinged connection with the mounting rail that allows an installer to assemble the module in a near perpendicular fashion to the mounting rail, make the required electrical connections and then lower the PV module into its working position. The unit is then locked into its working position.

Embodiments are provided for use with polyaxial pedicle screws and substantially straight shank pedicle screws in spinal applications. In a separate aspect of the invention, a bone screw connector having an interference type fit is also provided. A method for implanting the device is also provided.

A first flux-loop inductive coupler element electrically couples with a second flux-loop inductive coupler element. The first flux-loop inductive coupler element comprises a first ring-like core having high magnetic permeability and a conical-section annular first face transverse to the plane of the first core. The first face has a first annular groove separating a first conical-section larger-diameter face and a first conical-section smaller-diameter face. A first coil is wound within the annular groove. The first and second cores form a low-reluctance closed magnetic path around the first coil and a second coil of the second flux-loop inductive coupler element.A first current-loop inductive coupler element electrically couples with a second current-loop inductive coupler element. The first current-loop inductive coupler element has a first high-conductivity, low-permeability shaped belt of a first end of a first pipe joint, a first ring-like core located at the first end, and a first electrically conductive coil wound about the first ring-like core. The first high-conductivity, low-permeability shaped belt partially encloses the first coil. It is shaped to cooperate with the second high-conductivity, low-permeability shaped belt of an adjacent second pipe joint having a second electrically conductive coil and a second high-conductivity, low-permeability shaped belt to create a closed toroidal electrical conducting path. The closed toroidal electrical conducting path encloses the first coil and the second coil when the first and second pipe joints are mated.

An omni-positional hoist ring assembly including a bushing element that includes a sleeve with an axial length, a proximal end and a distal end. A load bearing flange is radially disposed about the proximal end of the sleeve. The sleeve has an internal thread extending at least part way of the axial length of the sleeve. A mounting screw element has a major axis, a head, and a shank disposed generally co-axially around the major axis. The shank includes a threaded shank portion and a bearing portion. The bearing portion is a generally cylindrical axially extending portion of the shank that has a diameter approximately equal to the minor diameter of the thread in the threaded shank portion. A thrust washer element is provided between the head and the distal end of the sleeve. A body element receives the in-turned opposed ends of the legs of a lifting loop element in sockets. The lifting loop is free to pivot. The body element is free to rotate about the sleeve, so the lifting loop will self align with a load that is applied to it from any direction within a hemisphere centered on the major axis of the mounting screw element. The elements of the hoist rig assembly are assembled by aligning them and inserting the mounting screw element into the sleeve and threadably advancing it until the bearing is aligned with the internal thread so further rotation of the mounting screw element does not threadably advance the mounting screw element relative to the sleeve.

A mounting bracket useful for securing a base, such as an antenna to a pole, a tube or a post, or a similar anchor support, and including a first clamp part, being a base clamp, to be secured to the base (the antenna) adapted to be locked against the pole, and a second clamp part, being tightening clamp, adapted to partly embrace the pole and to be tightened to the base clamp with the pole clamped therebetween, preferably by a screw-nut connection on each side of the pole. The tightening clamp, is formed with two elongated slots extending in the longitudinal direction of the clamp, a first slot of which may be closed and the second slot of which is open at the end of the clamp. The slots having a width matching the diameter of the clamp screws, a length which is at least twice the diameter of the clamp screws and arranged such that the open slot of the tightening clamp can be rotated freely past the corresponding bolt thereby engaging the corresponding clamp screw through the open end of the slot after the pole has been placed in contact with the base clamp. A tightening clamp and a base clamp can be joined in a rotational joint. Thereby an object, which is mounted, e.g. an antenna, can be panned.

A self-balanced adjustable mounting system for a flat panel display. A display interface having a hollow, semi-spherical shell portion is attached to the flat panel display. The semi-spherical shell is formed with a generally constant radius of curvature. The center of the radius of curvature is disposed proximate the center of gravity of the flat panel display with the display interface attached. The display interface is received in a guide structure that has a bearing portion engaging the outer surface of the semi-spherical shell, and a second bearing portion engaging the inner surface of the semi-spherical shell through an aperture formed in the semi-spherical shell. The semi-spherical shell is guided between the first and second bearing portions so that the flat panel display and device interface are generally rotatable about the center of the radius of curvature of the semi-spherical shell. The display is self balancing in virtually any position in the range of travel of the device due to the location of the center of rotation proximate the center of gravity.

Compression exerted by a clamp collar integral to a molded plastic flexible shaft coupling accommodating angular shaft misalignment upon the circumferential outward surface of a radially compressible molded sleeve insert located in a shaft bore of the flexible coupling facilitates engagement of a reduced diameter shaft located within the sleeve insert. Use of a sleeve insert having a different internal diameter similarly accommodates flexible coupling to another diameter shaft. Utilization of sleeve inserts selected from a plurality of different reduced internal diameters and exterior diameters sized to fit either shaft bore enables flexible coupling of both multiple matched shaft diameters and an exponential number of differing opposed shaft diameter combinations within a range limited by the flexible coupling shaft bores. Radial compressibility of the sleeve insert is facilitated by the utilization of resilient material, interruption of the circumferential extension by a longitudinal slot, or both. Utilization of congruent longitudinally uniform, radially non-uniform, flexible coupling shaft bore and insert sleeve outward surfaces provides additional torque transmission capacity.
