  • Publication number: 20150260545
    Abstract: A method and system for a non-intrusive parallel surface calibration for gyroscopes in a mobile device are described. In a mobile device having a gyroscope, multiple rotation matrices can be determined based on readings from the gyroscope. Each of these rotation matrices corresponds to a chain of rotations that occur when the mobile device is picked up from a surface and later placed down on any substantially parallel surface. In some instances, three or more rotation matrices can be determined. Calibration parameters can be computed from the rotation matrices and can be used to adjust subsequent readings from the gyroscope. An eigenvector can be determined for each of the rotation matrices and those eigenvectors can be used to obtain the calibration parameters through an optimization process. The gyroscope calibration can be triggered by a change in the temperature of the mobile device.

  • Publication number: 20140180230
    Abstract: A method of making an absorbent composite that includes a first fabric, a second fabric, and particles positioned between the two fabrics and absorbent articles made from the absorbent composite. The particles are secured between the two fabric using adhesive, thermal plastic or combinations thereof. The fabrics are bonded together in a manner that limits particle movement between the fabrics. The bond pattern may define pockets or other shapes. In applications in which the bond pattern forms pockets, the particles may be positioned in the pockets. The particles may be SAP particles or other particles with advantageous properties.

  • Patent number: 8600409
    Abstract: Techniques are described for obtaining high-resolution physical locations for a wireless device by leveraging the high-resolution physical location capabilities of wireless peers of the wireless device to provide a peer-to-peer location service and facilitate location targeting. Wireless devices provide location updates to a computing cloud, which stores records associating wireless device identifiers with received location information for the corresponding wireless devices. A wireless device issues a peer discovery request to dynamically identify nearby wireless peers in its network. The wireless device then sends wireless device identifiers for the nearby wireless peers in a location request to the computing cloud, which estimates a location for the wireless device using the previously recorded location information for the nearby wireless peers. The computing cloud returns the estimated location to the requesting wireless device.
