摘要： An apparatus and method for providing tracking and focus error signals for controlling an application of a radiation beam to a data track of an optical storage medium. A data signal, indicative of data stored on the medium, may also be provided. One apparatus in accordance with the present invention includes a multi-element beam separator, such as a quad prism, having first, second, third and fourth separator elements for separating a return beam reflected and diffracted from the data track into first, second, third and fourth portions, respectively. In other embodiments, more or less than four separator elements and return beam portions could be used. A focusing lens converges the portions of the return beam onto a detector array. The first and second separator elements, arranged on opposite sides of a plane substantially parallel to a reference plane defined by an optical axis of the radiation beam and a tangent to the data track, separate the return beam along at least one plane substantially parallel to the reference plane, and the resulting first and second portions are used to generate a tracking error signal. The third and fourth separator elements, arranged adjacent to and on opposite sides of the first and second separator elements, separate the return beam along planes substantially perpendicular to the reference plane, and the resulting third and fourth portions are used to generate a focus error signal.

摘要： Flow systems for photometric analysis of particles, such as biological cells, particularly for obtaining multidmensional slit-scan type contours, as well as other images. In one broad approach, fluorochrome-stained cells in suspension flow through a focused slit of laser excitation light defining a planar excitation region in the X-Y plane. As each fluorochrome-stained cell flows through the excitation region, fluorescence emissions are generated at the intersection of the excitation region and the cell. To generate a slit-scan type contour along the Z axis, fluorescence emissions are monitored as the cell flows through the excitation region and a plurality of substantially planar parallel cross-sections of the cell along the Z axis are excited to fluorescence. To generate slit-scan type contrours along the cellular X and Y axes, various optical system embodiments define various combinations of cellular linear portions within the Z axis cross-section. The fluorescence or other emissions from these cellular linear portions are then combined by integrating to generate the desired contours. In another broad approach described, a three-dimensional volume of a cell in flow is illuminated with exciting radiation which is not a narrow beam. Three optical systems view a central point in the flow system. The optical systems are slit-imaging and have three respective axes orthogonal to each other and symmetrically located about the stream such that the axis of flow forms equal angles with each optical axis. A photomultiplier tube for each optical system detects the imaged cell fluorescence.

摘要： An orthopedic plate is designed for opening osteotomies and includes a contoured double tabbed or butterfly shaped plate portion which can accommodate selective fixation including locking, variable locking and non-locking. The plate also includes a centrally located osteotomy support that maintains the opening between bone segments at a spaced relationship. The support can be integral to the plate, or can be modular, i.e. a separate and adjustable segment which can be changed to accommodate the desired geometry of the osteotomy site.

摘要： A cannulated compression screw is used as an orthopedic implant and has a threaded distal end with an insertion tip that includes at least one and preferably two, three or four flutes to allow the screw to be self-tapping. Optionally, the screw also includes one or more reverse cutting flutes proximal to the insertion tip. The distal threads are cancellous threads having a generally constant minor diameter and a generally constant major diameter and a generally constant thread pitch. An intermediate portion of the screw is non-threaded and the proximal end includes a compression wedge or taper that has at least one, and preferably two to five flutes that terminate before the top of the screw. The proximal end further includes a radiused bevel to the terminal surface that includes a hexagonal torque driving recess. The diameter of the non-threaded shaft section is constant distal from the compression wedge to the distal tip where it defines the minor diameter of the threaded portion. The screw optionally includes a tapered insertion tip.

摘要： The present invention relates to an orthopedic screw and a corresponding screw driver wherein the screw has a torque driving head with a rounded side a spherical wall for multiaxial use, a self starting, self tapping insertion tip and a threaded portion including a cancellous thread. The threaded portion has a major diameter defined by a spiraling thread and a minor diameter. The head is joined to the threaded portion by an area of from about 2 to about 6 turns of the thread along the longitudinal axis in which the minor diameter tapers by an angle of from about 4° to about 12° and the major diameter of the screw remaining substantially the same. The screw includes a multilobe torque driving recess joined to a cylindrical recess that corresponds to a cylindrical post on the torque driver so as to form a press fit which acts to self-center the screw, to help avoid stripping of the screw/driver interface and to hold the screw in place on the torque driver prior to implantation.
