  • Patent number: 9230576
    Abstract: Embodiments disclosed herein generally relate to a magnetic head having a sensor stack and a bias material that is aligned in a direction perpendicular to a media facing surface. The sensor stack and a first portion of the bias material are laterally bookended by synthetic antiferromagnetic (SAF) structures, and a second portion of the bias material is laterally bookended by a dielectric material. In this configuration, the SAF structures are decoupled from the bias material, which minimizes the disturbance to the bias material.

  • Patent number: 8775682
    Abstract: Computer-implemented methods for synchronizing data between a server and a client are provided. In one aspect, a method includes receiving a request from a client to synchronize data. The request includes a synchronization token that includes client recent synchronization signatures, each client recent synchronization signature representing a state of data synchronization on the client for a certain time period. The method also includes comparing each client recent synchronization signature with a corresponding server recent synchronization signature representing data on a server for the same time period. When the comparison indicates that the data on the client for the time period represented by the client recent synchronization signature is not synchronized with corresponding data on the server for the time period, then the method includes sending the data on the server for the time period to the client. Systems and machine-readable media are also provided.

  • Patent number: 8217376
    Abstract: Several methods of calibrating a wavelength-modulation spectroscopy apparatus configured to measure a concentration of an analyte in a sample gas are disclosed. Each of the methods allows for calibration and recalibration using a relatively safe gas regardless of whether the sample gas for which the concentration of the analyte can be determined is a hazardous gas. In one embodiment of the invention, calibration that is sample-gas specific is accomplished by determining a first slope coefficient and calibration function for the sample gas, after which a scaling factor can be determined based on the first slope coefficient and a second slope coefficient for the same or a different sample gas and used in a subsequent calibration (or recalibration) to scale the calibration function. In other embodiments of the invention, calibration that is not sample-gas specific is accomplished to allow for the determination of the analyte concentration in variable gas compositions and constant gas compositions.
