  • Patent number: 11735214
    Abstract: Systems and methods are disclosed for synchronous writing of a grain patterned medium. The systems and methods can be implemented within a data storage device having a grain patterned medium. Further, a calibration process to determine a count of bits between servo wedges can be implemented in manufacturing, within the data storage device, or both. In some examples, the data storage device, during operation, can utilize the count of bits to perform synchronous writing, determine write errors, or both. Further, the servo wedge of the grain patterned medium may be patterned with a same or similar grain pattern as the data area that follows the servo wedge. Such a data storage device can implement a single clock for reading a servo wedge and writing a data area.

  • Patent number: 11733393
    Abstract: Embodiments of the present invention provide a method, system and computer program product for bit transition enhanced direct position estimation (DPE) from global navigation satellite system (GNSS) signals and includes the reception in a GNSS receiver of signals from multiple, different satellites in multiple satellite constellations adapted for use with the GNSS. The method estimates the GNSS receiver parameters position, velocity, clock bias, clock drift, and optionally and if unknown, the receiver time. The method generates a model of the received GNSS signals that depends on the receiver parameters. Uniquely, the method includes the synchronization of both a primary code and also a secondary code in the received GNSS signal model, in addition to time delays, Doppler shifts, and other relevant parameters for positioning. Finally, if the secondary code of a particular signal is unknown, the method determines the combination of bit transitions that maximizes the optimization problem.
