Method and apparatus for determining acetabular component positioning
ActiveUS20090306679A1Solve precise positioningError componentJoint implantsDiagnostic recording/measuringAcetabular componentMedicine
An instrument for establishing orientation of a pelvic prosthesis comprises a tri-pod having an angularly adjustable guide rod on it. The tips of the legs define a plane, and the guide rod is set by the surgeon to a defined orientation with respect to this plane on the basis of preoperative studies. In use, two of the legs of the instrument are positioned by the surgeon at defined anatomical locations on the pelvis (e.g., a point in the region of the posterior / inferior acetabulum and a point on the anterior superior iliac spine). The third leg then lands on the pelvis at a point determined by the position of the first two points, as well as by the separations between the third leg and the other two legs. The separations are adjustable, but are preferably fixed percentages of the separation between the first and second legs. The position of the guide rod then defines with respect to the actual pelvis the direction for insertion of a prosthesis.

Miniaturized inclinometer for angle measurement with accurate measurement indicator
InactiveUS6871413B1Accurate measurementUnlimited 360 degree resolutionAngles/taper measurementsUsing electrical meansMultiplexerSignal conditioning
The novel miniaturized inclinometer for angle measurement with accurate measurement indicator is designed to monitor the angular motion of limbs. The device contains at least one inclinometer with signal conditioning electronics, including a microprocessor, placed within a miniature housing. A number of different sensors can be used and positioned in their housings so that their outputs vary as a function of their angle with respect to the gravity sector. The microprocessor controls a multiplexer, which controls the activities of the sensors; performs analog to digital conversions and measures the output curves from the sensor pairs to perform a conversion which results in a three hundred and sixty degree range with respect to gravity. Calibration data is stored in a read only memory and the microprocessor corrects variables to ensure accuracy and measures the difference in angle between the pairs of sensors.

A positioning and calibration system are provided for use in calibrating a single or multi axis sensitive instrument, such as an inclinometer. The positioning system includes a positioner that defines six planes of tangential contact. A mounting region within the six planes is adapted to have an inclinometer coupled thereto. The positioning system also includes means for defining first and second flat surfaces that are approximately perpendicular to one another with the first surface adapted to be oriented relative to a local or induced reference field of interest to the instrument being calibrated, such as a gravitational vector. The positioner is positioned such that one of its six planes tangentially rests on the first flat surface and another of its six planes tangentially contacts the second flat surface. A calibration system is formed when the positioning system is used with a data collector and processor.

Multi-purpose measuring tool
A multi-purpose measuring tool has an elongate base and arm pivotally connected at rounded ends thereof in an angularly variable relation to perform multiple functions, including measuring inclines, measuring corner angles, measuring distances, use as a square, use as a bevel gauge and use as a torpedo level. A retractable measuring tape housed within the arm has a terminal finger gripping end adapted to be pulled away from the arm and removably attached to a distal end of the base. The measuring tape is dual purpose in that one side of the tape is used for determining the angle of the arm relative to the base to perform some of the above functions, and the other side of the tape is used for traditional linear distance measurements. The tool's base includes a "vertical" bubble level and the arm includes a "horizontal" bubble level to perform some of the above functions.

Pipe-bending alignment device
InactiveUS6385856B1Accurate measurementReduce manufacturing costAngles/taper measurementsIncline measurementEngineeringAngle gauge
An economical, compact guide for introducing multiple bends in one or more planes in a pipe, conduit, or other tube-like item. The guide has a gauge section rotatably attached to a mounting section and is affixable by means of a non-deforming clamp to the end of a pipe segment to be bent. The gauge section has a bend-angle gauge and a bend-plane level. The bend-angle gauge is a plumb arm mounted so as to measure and indicate the bending of a pipe to any degree of bend. The bend-plane guide is a 360° level mounted on an upper face of the plumb arm. Multiple bends are made in the pipe segment without removing or re-aligning the guide. This ensures that the initial reference position is maintained throughout the bending process and ensures that all bends are in the proper bend-plane, thus avoiding "dogging" between successive bends. Multiple successive bend-planes also may be established without removing or re-aligning the guide on the pipe, by rotating the gauge section of the guide relative to the mounting section by the magnitude of the desired out-of-plane angle.

Snap locking angle adjustable device, in particular a carpenter's square
The invention is a snap locking angle adjustable device, particularly applicable to carpenter's squares. Carpenter's squares, being used in rough environment, must be simple to adjust while providing robust snap locking at high angle precision. Prior art attains this by protruding steel balls, attached around the pivot axis of the square's handle, pressed strongly against a hole punched area around the pivot axis of the square's blade-balls aligns to holes gives the snap locking. The problem is to simplify manufacturing. The invention comprises components with moulded alignment structures. These components are the complete pivot members (handle or blade) themselves, or are separately attached to the pivot members. The components, and optionally, are sandwiched, alignment structures against each other, and axially pressed together strongly by a spring held in compression by a press frame that also may constitute a pivot shaft for the pivot members.

Optical inclination sensor
An optical inclination sensor is provided having at least one reflective surface and at least two separate optical fibers having ends spaced from a reflective surface. As the reflective surface tilts with respect to a pre-determined reference position the gap lengths between the fiber ends and the reflective surface change and the differences in these gap lengths is used to calculate an angle of inclination with respect to a reference position. The optical inclination sensor can include at least one mass attached to a housing and moveable with respect to the housing as the mass and housing are rotated about one or more axes. Optical strain sensors are disposed a various locations between the mass and housing so that as the mass moves with respect to the housing, each one of the optical strain sensors are placed in compression or tension. The housing can be a generally u-shaped housing having two arms and a base section with the mass disposed within the housing. Alternatively, the housing includes a first beam, and the mass is a second beam arranged generally orthogonal to the first beam and pivotally attached thereto. The optical strain sensors are disposed between the first beam and the second beam.
