  • Publication number: 20240097696
    Abstract: Example channel circuits, data storage devices, and methods for asynchronous sampling from an oversampled analog-to-digital converter are described. The channel circuit may include an analog-to-digital converter configured to generate an oversampled digital signal from an analog data signal using a sample rate that is an integer multiple of the baud rate of the channel circuit. A digital sample interpolator may then interpolate interpolated digital signal values from multiple signal values of the oversampled digital signal and select values at baud rate to generate a baud rate digital signal. The baud rate digital signal may be used by an iterative detector in a timing loop and, once a target timing is achieved, for the iterative detector to detect data bits from the interpolated digital signal.

  • Patent number: 4862762
    Abstract: A touring bicycle handlebar and reversible brake adaptor lever comprising of a handlebar having straight bar lengths extending equidistantly on each side of the handlebar boss providing the cyclist with the means to assume a hands on semicrouched posture, each straight bar length terminated by bent portions extending the bar upwardly above the level of the first straight portions to second straight portions with further bent portions extending the bar forwardly and downwardly, providing the cyclist with the means to assume a hands on upright posture, with third straight portions providing a means for mounting the brake lever assemblages, the third straight portions terminated by bending the bar backwardly to provide straight portions that extend beyond and below the first straight portions providing the cyclist the means to assume a hands on crouched posture and of a brake lever to replace the levers of the drop racing handlebar brake assemblages permitting the mounting of the modified assemblages on the tour

  • Patent number: 4729957
    Abstract: A process for the recovery and purification of L-asparaginase from Erwinia chrysanthemi is disclosed. The process involves the preparation of cellular acetone powder extract followed by either an ion exchange and affinity chromatography purification steps or by affinity chromatography alone. The column eluent is then dialyzed to produce substantially pure L-asparaginase.
