摘要:
A method comprises creating calibration data using a first control circuitry of an apparatus, replacing the first control circuitry with a second control circuitry in the apparatus, and operating the apparatus with the second control circuitry using the calibration data. As an example, the apparatus may be a disc drive. The second control circuitry may be substantially similar to the first control circuitry such that calibration measurements using the first control circuitry are applicable to the second control circuitry. The first control circuitry may be included in a circuit board that is replaced with a second circuit board including the second control circuitry. In an exemplary embodiment, the second circuit board may include different and/or additional components relative to the first circuit board, such as integrated video inputs and/or video control circuitry.

This application describes surgical instruments and implants for building a posterior fixation construct across one or more segments of the spinal column. Extension guides are provided that attach to bone anchors implanted within the spine. The extension guides have a guide channel that align with a rod channel in the anchor to help direct the rod to the anchor. Instruments are provided to aid in insertion and positioning or the rod.

A data storage subsystem in a distributed storage system having a plurality of predictive failure analyzing data storage devices. The subsystem furthermore has a circuit that is responsive to a predicted failure indication by a data storage device in relation to predetermined rules stored in memory for deterministically initiating a preventive recovery either by a data recovery procedure in the data storage device or by a fault tolerance storage arrangement in the subsystem.

This application describes surgical instruments and implants for building a posterior fixation construct across one or more segments of the spinal column. A fixation anchor is provided that includes a break off extension guide that extends from an anchor housing which captures a fixation rod. The extension guide has a guide channel that aligns with a rod channel in the housing to help direct the rod into the housing. The extension guide includes proximal breakable joints that allow the arms of the extension guide to be separated to facilitate rod insertion. Distal breakable joints are provided to allow the arms of the extension guide to be removed. Features and instruments for reducing the rod through the extension guide are also provided.

This disclosure describes example embodiments of rod reduction instrumentation and other rod and vertebrae manipulation instruments. The rod reducers can be used during the installation of a rod based surgical fixation system to help urge the rod into the fixation anchors. The reducers described provide various configurations delivering large reduction distance capabilities, strong controlled reduction coupled with an ability to quickly advance the reducer if desired, and reduction of bulk through the surgical corridor.

The present application describes a pedicle fixation system and methods for correcting deformities of the spine and fixing the corrected portion of the spine in a corrected position. The disclosed system and associated methods include at least one pedicle screw in which a receiver portion of the pedicle screw is coupled to a screw portion of the pedicle screw in a manner such that the receiver portion is initially movable relative to the screw portion in a polyaxial fashion and subsequently lockable relative to the screw portion prior to locking a rod in the housing. Instruments for locking the receiver portion relative to the screw portion are also described.

The present invention involves a system and methods for assembling and implanting a polyaxial bone screw assembly. The polyaxial bone screw assembly includes, but is not necessarily limited to, a bone screw that can be initially secured to a bony structure and subsequently have a receiver assembly attached to the implanted bone screw. Additionally, a closure structure is a part of the polyaxial bone screw assembly and functions to secure an elongate member within the receiver assembly.
