Latest Patents

Todd G. Culman holds a patent for a "Hard disk drive with self-contained active acoustic noise reduction." This invention features an active noise reduction system designed to minimize the acoustic noise generated by hard disk drives. The system integrates seamlessly into the hard disk drive and produces an acoustic waveform that is 180 degrees out-of-phase with the noise produced by components such as the spindle motor and voice coil motor (VCM). The noise is detected through a microphone or indirectly via the read/write head, spindle motor driver, or VCM driver. The electronics process the acoustic noise, and the noise-canceling waveform is either retrieved from the hard disk drive's memory or generated by the electronics. This waveform is then broadcasted through integrated transducers within the hard disk drive.
