Abstract:
A system for restricting spinal flexion includes superior and inferior tether structures joined by a pair of compliance members. Compliance members comprise tension members which apply a relatively low elastic tension on the tether structures. By placing the tether structures on or over adjacent spinous processes, flexion of a spinal segment can be controlled in order to reduce pain.
Abstract:
A surgical fastening mechanism for releasably locking an implantable tether includes a housing having a central channel. The housing has an entry aperture, an exit aperture and a side channel extending therebetween. A roller element has a sidewall with an aperture therethrough and the roller is slidably disposed at least partially in the central channel such that the entry and exit apertures are at least partially aligned with the roller aperture. This permits passage of the tether therethrough. Rotation of the roller element in a first direction winds the tether around the roller thereby creating a friction interface between the roller element, the housing and the tether. A locking mechanism is operably connected with either the housing or the roller element and is adapted to prevent rotation of the roller in the central channel and also adapted to prevent release of the tether from the roller.
Abstract:
An intelligent query system for processing voiced-based queries is disclosed, which uses semantic based processing to identify the question posed by the user by understanding the meaning of the user's utterance. Based on identifying the meaning of the utterance, the system selects a single answer that best matches the user's query. The answer that is paired to this single question is then retrieved and presented to the user. The system, as implemented, accepts environmental variables selected by the user and is scalable to provide answers to a variety and quantity of user-initiated queries.
Abstract:
A spinal implant system for restricting flexion of a spine includes an elongate band proportioned to engage at least two spinous processes. During use, the band is positioned engaging the spinous processes at a spinal segment of interest, where it restricts flexion at the segment. The length and tension of the band may be adjustable following to implantation using percutaneous or transcutaneous means.
Abstract:
A system for restricting flexion of a spinal segment in a patient comprises a constraint device having a tether structure and a compliance member coupled with the tether structure. The tether structure is adapted to be coupled with a superior spinous process and a sacrum. The system also includes an anchor member that is anchored to the sacrum. The anchor member has an attachment feature that is adapted to couple with the constraint device.
Abstract:
A bearing assembly (2′) comprising a housing (3′) supporting first and second bearing ring portions (4, 4′) with bearing surfaces to engage an inner tubular member (1′) at axially spaced regions, characterised in that either: said bearing ring portions are provided by separate bearing rings (4′) supported in the housing member (3′) with bearing surfaces of different diameters; or said bearing ring portions are provided by a single bearing ring (4″) that is free to flex radially and is supported so that the second bearing ring portion is free to flex radially under load and its bearing surface than assumes a position with a greater diameter than that of the first bearing ring portion (4″).

Abstract:
Speech signal information is formatted, processed and transported in accordance with a format adapted for TCP/IP protocols used on the Internet and other communications networks. NULL characters are used for indicating the end of a voice segment. The method is useful for distributed speech recognition systems such as a client-server system, typically implemented on an intranet or over the Internet based on user queries at his/her computer, a PDA, or a workstation using a speech input interface.
Abstract:
A speech recognition system includes distributed processing across a client and server for recognizing a spoken query by a user. A number of different speech models for different natural languages are used to support and detect a natural language spoken by a user. In some implementations an interactive electronic agent responds in the user's native language to facilitate an real-time, human like dialogue.
