摘要： A timing recovery loop includes a random walk filter counter for counting early, nominal and late arrivals of data transitions pulses of an input baseband signal waveform encoding a digital bit stream, and provides magnitude counts that are compared to a threshold value that when exceeded by the magnitude counts results in a delay adjustment of the generated adjusted timing pulses then remaining synchronized with the actual bit timing for maintaining bit timing lock. The adjusted timing pulses can then be used by a data detector for reliable data detection and reconstruction of the digital bit stream. The threshold value can be adaptively adjusted for reducing drop lock rates in the presence of changing channel environments.

摘要： Fluid storage and dispensing system comprising a pressure vessel having a moveable partition member dividing the interior into first and second variable volumes. The first variable volume has a first passage adapted for the inflow and outflow of a product fluid and the second variable volume has a second passage adapted for the inflow and outflow of a compensating gas. The system includes (1) a compensating gas line for providing compensating gas, (2) a first orifice that is installed in the compensating gas line and has an upstream side and a downstream side, (3) a compensating gas vent line connected to the compensating gas line between the second passage and the downstream side of the first orifice, and (4) a second orifice installed in the compensating gas vent line, wherein the cross-sectional flow area of the second orifice is smaller than the cross-sectional flow area of the first orifice.
