Latest Patents

Device and Method for Generating Synchronous Numeric Signals. This invention describes a device that generates synchronized signals at a reference frequency. It combines a reference-generating device with a timed-generating device and a synchronization stage. The stage produces a controlled-frequency timing signal and phase-synchronization pulses with a programmable delay relative to the reference timing signal.

Noise Compensation Device and Method in a Discrete Time Control System. This invention concerns noise compensation in discrete-time control systems, including read/write systems for hard disks. A control loop produces timing, measurement, and control signals, while an open-loop control line generates a synchronized compensation signal. A sensor and acquisition stage measure disturbances, and a synchronization stage uses timing signals to coordinate the acquisition process.

Career Highlights

Hernden’s listed patents focus on coordinating signal timing and improving control-system performance. The inventions describe techniques for synchronizing generated signals and measuring disturbances so that compensation can be aligned with a system’s control signals.
