    • A diffractive/refractive hybrid lens for use in an optical data storage system as an objective is provided by a convex-plano singlet having a refractive element defined by plano-convex surfaces and a diffractive element defined by a Fresnel zone-like pattern on the plano surface which together provide the total power of the lens. The refractive lens is made of a high index, high dispersion glass so that the curvature and thickness of the refractive lens is minimized while providing a large numerical aperture (at least 0.45) at the expense of increased longitudinal chromatic aberration, which are compensated by the diffractive element and without the need for one or more additional curved surfaces as in low index biaspheric glass objective lenses for chromatic and mono-chromatic aberration reduction, which increases the thickness and curvatures of the lens. The invention enables longitudinal chromatic aberration to be corrected for at least a 10 nm band width around a center wavelength over a 20 nm range, as results when different lasers are used and as laser power varies during optical data storage on an optical data storage device (an optical disk). The thin, light weight low curvature achromat has maximum tolerance for various possible manufacturing errors such as decentering, variations in thickness of the lens, tilt and focal length especially for on-axis field of view less than 2.degree. while providing a very high quality spot (Strehl ratio of at least 0.9.).

    • A method and system are disclosed for retrieving information through the use of a multi-stage interaction with a client to identify particular knowledge content associated with a knowledge map. The present invention is an application program running on a server accessed via the world-wide web or other data network using standard Internet protocols, a web browser and web server software. In addition to an automated portion, the present invention allows a human dialog designer to model the way the system elicits information, giving a human feel to the dialog and a better customer experience. In operation, users start a dialog by directing their web browser to a designated web page. This web page asks the user some initial questions that are then passed to a dialog engine. The dialog engine then applies its methods and algorithms to a knowledge map, using dialog control information\ and the user's responses to provide feedback to the user. The feedback may include follow-up questions, relevant documents, and instructions to the user (e.g., instructions to contact a human customer service representative). This dialog engine response is rendered as a web page and returned to the user's web browser. The user can then respond further to the follow-up questions he or she is presented, and the cycle repeats. The invention can be implemented so that it can interact with customers through a wide variety of communication channels including the Internet, wireless devices (e.g., telephone, pager, etc.), handheld devices such as a Personal Data Assistant (PDA), email, and via a telephone where the automated system is delivered using an interactive voice response (IVR) and/or speech-recognition system.

    • An orthopedic plate has a portion with a curved bottom surface that is designed to extend longitudinally along the bone and change the inferior curve as it advances proximally along the bone from a shallower to a sharper radius and further spirals downward as the plate advances. The plate includes a set of tabs, offset from the longitudinal axis of the plate to provide for better pullout values. The ears may be located at the terminal portion of the plate or somewhat more intermediate to the terminus of the plate, depending on the intended application. A point in the center of the central screw hole can be used to define the origin of the plate, and the angles of the screw and/or pegs holes can be referenced with Z, Y, and Z coordinates relative to this central hole.

    • A compression wire is partially threaded and has a trocar insertion point for insertion into a bone segment to be stabilized with respect to a second bone segment. A button mates with the wire and is crimped into position on the wire to cause compression and stabilization between the bone segments. A cannulated instrument is used to grasp and apply tension to the wire at a given torque, and further to crimp the button to maintain tension on the wire in a location suitable for later removal. In a second embodiment for osteoporotic bone the wire further includes an internally threaded screw or helix which is implanted into the bone segment to mate with the threads of the wire. The invention further relates to the method of bone stabilization where the threaded wire is implanted into the distil end of a bone segment in ante grade or retro grade and also in a sub-cutaneous or percutaneous fashion and extending through an adjacent bone segment. An end of the wire protrudes from the second bone segment and end receives a button slid onto the wire and crimped into the desired tension. The end of the wire assembly may be left proud for later removal, or countersunk in the bone so as not to protrude.
