Abstract: The present disclosure relates to a valve tray for use in a chemical process column. The valve tray includes a plurality of apertures formed therein. A plurality of valves are maintained in a spaced relationship relative to individual apertures of the plurality of apertures. An area of the individual apertures is less than an area of individual valves of the plurality of valves.

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.

Abstract: An apron assembly comprising a panel of flexible material adapted to overlie a frontal portion of a user's torso, a first connector disposed proximate a bottom edge of the panel, second and third connectors disposed along a first side edge thereof, fourth and fifth connectors disposed along a second side edge thereof, and a sixth connector adapted for attachment to an edge of a tray, the first and sixth connectors being interengageable to connect the panel to the tray and form a pocket, the second and third connectors being interengageable to close a first end of the pocket, and the fourth and fifth connectors being interengageable to close a second end of the pocket.
