Abstract: The disclosed fluidic device may include (1) a channel configured to transport fluid from a source to a drain and (2) a gate configured to modulate fluid flow through the channel. The gate may modulate fluid flow by bending a gate actuation membrane that alternates between an initial configuration that does not interfere with a cross section of the channel and a bent configuration that causes the cross section to reversibly compress. The gate actuation membrane may include an undulation that facilitates the bending of the gate actuation membrane.

Abstract: The system provides a control and management solution for linked gaming machines in a progressive game environment. The system can track multiple meters so that multiple progressive jackpots can be maintained for each game and/or for multiple participating business entities sharing in game revenue. Correspondingly, multiple progressive display meters can be controlled for each game machine. The system is scalable from near area progressive systems to wide area progressive systems. In the event that communication is lost with in a wide area progressive environment, one or more game machines may automatically switch to near area progressive behavior until communication is restored. The system is independent of currency and denomination limitations by employing and converting currency as units instead of particular denominations. Game machine population and participation can be remotely managed, updated, and changed from a central management location.
