Abstract: A method of recovering a servo write frequency, to read servo wedge data from a rotating magnetic storage medium having at least one servo wedge that includes a servo preamble written at a known preamble frequency, includes analyzing samples of data read from the rotating magnetic storage medium to identify samples in which energy at the known preamble frequency exceeds a predetermined threshold, declaring the location of the servo preamble based on the identification of the samples in which energy at the known preamble frequency exceeds the predetermined threshold, deriving a phase angle from the samples in which the energy at the known preamble frequency exceeds the predetermined threshold, updating an accumulated phase angle using the derived phase angle, and using the updated accumulated phase angle to start a timing recovery loop to recover the servo write frequency. The analyzing and deriving may be performed using a spectral analysis operation.

Abstract: Embodiments described herein provide methods and systems for correcting a transient phase error induced while recording on a magnetic recording medium. An input signal is received and is distributed to a plurality of sinc filters. A respective phase-shifted signal is generated at each of the plurality of sinc filters by adding a corresponding predetermined amount of phase to the received signals. A respective score is assigned to each of the generated phase-shifted signals. The generated phase-shifted signal having the highest score is selected as the phase-corrected signal to compensate for the transient phase error induced while recording on the magnetic recording medium.

Abstract: An improved handrail splice for use in coupling cylindrical handrail components comprises a generally cylindrical splice having a scalloped outer surface defining a plurality of first and second grooves, with the first grooves being characterized as large grooves circumferentially spaced along the outer surface and a plurality of smaller second grooves disposed between the first grooves. The large grooves are sized to receive and maintain a quantity of adhesive therein to ensure a secure adhesive connection between exterior of the tubular splice and the interior handrail surface. The smaller second grooves receive a smaller quantity of adhesive and further function to anchor the splice relative to the hand rail sections by press-fit engagement. A longitudinal slit bounded by a pair of projecting tabs allows for the temporary reduction of the splice to facilitate inserted installation of the splice within a tubular hand rail component.

Abstract: Systems, methods, apparatus, and techniques are provided for producing an estimate of a digital sequence. A continuous-time signal is obtained. The continuous-time signal is sampled with an oversampling factor to produce a discrete-time signal corresponding to the continuous-time signal. A phase offset estimate of the continuous-time signal is produced based on the discrete-time signal. The discrete-time signal is interpolated based on the phase offset estimate to produce an interpolated discrete-time signal. The interpolated discrete-time signal is processed to produce an estimate of a digital sequence.
