An adjustable spinal fixation system is composed of a collection of anchoring assemblies attached, via a variety of connectors, to spine-stabilizing rods. The anchoring assemblies include a linking member attached in a ball-and-socket fashion to a bone-engaging member that is adapted to engage a spinal bone of a patient. The linking member joins one of the included connectors to an associated bone-engaging member. The connectors are selectively attached to one of the stabilizing rods. The anchoring assemblies each include a support collar and a split retention ring that cooperate to allow adjustment of the bone-engaging member and corresponding connector during surgery. When surgery is complete, a linear engaging fastener cooperates with the support collar and split retention ring to maintain the relative position of the entire fixation system, preventing unwanted movement between the system components.

A bone block for insertion into a patient's intervertebral space. A method for inserting a bone block into a patient's intervertebral space, comprising: supporting the bone block in an inserter; advancing the inserter into the intervertebral space; rotating the inserter, thereby separating adjacent vertebrae; separating the bone block and the inserter with a push rod; and removing the inserter from the intervertebral space.

The present invention is an extremely compact three leaf geared hinge that is adapted to handle heavy loads, tightly fold back onto itself for space conservation, offer extensive freedom of movement in the horizontal plane and provide an extremely smooth operating action with minimal play in torsion as well as in axial or transverse motions. The hinge has three interconnected leaves jointed by hinge pins. The inner and outer leaves each have two fixed gears on their sides that meshingly engage a set of two rotating gears located on the sides of the middle leaf. The inner leaf has a cylindrical leaf and pin arrangement on one end that may be rotatably secured to a rigid member or housing. The free end of the outer leaf may be attached to the load directly or with a device that allows the load to rotate normally about the extended hinge.

An apparatus is presented in which a sample can be accurately repositioned in a spectroscopic and / or imaging apparatus upon multiple insertions, and where the apparatus can be worn by living subjects for extended periods of time. The apparatus additionally reduces the temperature increase and stabilizes the temperature of the sample upon irradiation with an optical source of excitation. Additionally, the apparatus stabilizes the pressure and critical optical properties of the sample and its interface with the apparatus. Alternatively or additionally, the apparatus can be used to alter and / or substantially reduce fluorescence from targeted fluorophores in the sample.

Some embodiments allow a video editor to remove unwanted camera motion from a sequence of video images (e.g., video frames). Some embodiments are implemented in a video editing application. Some of these embodiments distinguish unwanted camera motion from the intended underlying motion of a camera (e.g., panning and zooming) and / or motion of objects within the video sequence.

A stabilized support for supporting motion-sensitive, ultra-lightweight, camera equipment includes a hollow platform on which the camera equipment is mounted, and a structure on which the platform is detachably mounted. The structure has a handle, a counterweight mounted below the platform, and an arm for connecting the handle with the counterweight. The platform has a plurality of interior compartments preferably arranged in generally parallel rows at opposite sides of the platform, each row extending past a center of gravity. A plurality of ballast weights is held and confined in the interior compartments within the platform to balance the support when held by the handle, or supported by optional support legs. The placement of the ballast weights is based on a balancing procedure in which the camera equipment is balanced relative to a stationary horizontal support surface.

Provided is an offshore wind turbine installation arrangement, including a lifting assembly realized to hoist a suspended load between a floating installation vessel and a wind turbine assembly, the lifting assembly including a crane supported by the floating installation vessel; a sensor arrangement realized to sense at least a motion of the floating installation vessel; and a controller realized to control elements of the lifting assembly on the basis of the sensed installation vessel motion to adjust the position of the suspended load relative to the wind turbine assembly. Also provided is a method of hoisting a load between a floating installation vessel and an offshore wind turbine assembly.

A double pendulum gravimeter accurately measures gravity by transferring aligned mode energy between suspension points of the pendulums to establish equal arcs of oscillation of the pendulums and by sensing oscillation characteristics to establish an accurate gravity value including a correction factor which depends on the arc of oscillation, while absorbing adverse mode energy.

A support device provides elevation and support for a patient's foot, including ankle and heal, and limits lateral and medial rotation of the foot. This protects the knee from injury while healing. The device includes a generally flat main body, two spaced-apart lateral ridges, and a medial depression between the lateral ridges that provides a support surface on which the foot may be positioned. The lateral ridges can extend to a height above the support surface so that inner side surfaces of the lateral ridges are adjacent to a majority of a foot placed in the medial depression. The lateral ridges can terminate below a top of the foot to permit unrestricted ventilation and access to the foot. The lateral ridges can be spaced apart to facilitate placement of a foot onto and removal of the foot from the support surface without manual manipulation of the device.

A headlamp assembly comprising a light source and a housing for the light source, a dampening element for dampening movement of the housing in or generally along at least one axis in response to dynamic loads during operation of the vehicle, while permitting movement of the housing in a predetermined direction. Another embodiment comprises a headlamp assembly comprising a light source and a support housing having a projection extending from the support housing. At least one isolator is mounted on the projection and a bracket comprising a working surface generally opposes a landing surface of a landing. The working surface comprises a slot adapted to receive a post and permit the post to move in the slot. The at least one isolator cooperates and engages the working surface or the landing surface to dampen movement of the support housing in response to dynamic loads during operation of the vehicle.

A device for stabilizing boats and other watercraft that is generally blade-shaped and attaches to the body or hull of the boat. The stabilizing device projects generally outwardly and downwardly from the boat and is pivotally connected along the vertical axis at the attachment point to the watercraft. The device dramatically improves the stability of the boat and resists stops unwanted drift either from a stationary position or from a desired heading.

A method and hardware for damping and controlling unwanted motion in the fixed rigging of large machines. In a first approach large clamp blocks are added to multi-cable rigging systems. These blocks use a first cable to damp the motion of an adjacent cable. The invention also encompasses adding armored sections to synthetic cables to enhance their abrasion resistance and cut resistance.
