Polyaxial bone screw with torqueless fastening
ActiveUS20050070899A1Avoid disassemblyLarge caliberSuture equipmentsInternal osteosythesisBiomedical engineeringBone screws
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.

Picoprojector with Image Stabilization [Image-Stabilized Projector]
InactiveUS20120113514A1Unwanted motionReduce quality problemsOptical elementsUnintended MovementImage stabilization
A handheld projector is provided with an image stabilization system that acts to reduce (or even eliminate) unwanted motion of the projected image due to unintended movement of the projector. In certain preferred embodiments, a solid-state motion sensor provides input to an image stabilization system that computes a corrective signal. In embodiments having optical image stabilization, the corrective signal is supplied to a mechanical actuator that moves one or more optical elements within the projector. Other embodiments have electronic image stabilization. In these embodiments, the corrective signal from the image stabilization system is used by the image generator to shift the image so as to compensate for movement of the projector.

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.

Stabilization of three-dimensional images in a scannerless range imaging system
ActiveUS6925195B2Small degreeUnwanted motionTelevision system detailsImage analysisThree-phaseImage motion
A method for generating a stabilized three-dimensional image from a scannerless range imaging system comprises the steps of acquiring a bundle of three or more phase offset images corresponding to modulated illumination reflected from a scene, whereby one or more of the phase offset images includes image motion relative to another phase offset image; searching for a stable chain of phase offset images in the image bundle, wherein a stable chain is a collection of images that is obtained by testing the phase offset images against a confidence measure that separates less severe correctable image motion from more severe image motion and then populating the stable chain only with those phase offset images that meet the confidence measure for correctable image motion; correcting for the image motion in the stable chain of images if a stable chain of at least three phase offset images is found to exist; and computing a stabilized three-dimensional image using the phase offset images from the stable chain of phase offset images.
