Abstract: A system for preventing asynchronous rotation in aircraft components includes an optical emitting source, an optical receiver, and a retroreflector configured to be disposed on a rotating component connected to an engine of an aircraft. The system emits radiant flux from the optical emitting source towards the retroreflector when the retroreflector is on the rotating component and the engine positions the rotating component into a field of view of the optical emitting source; receives incident radiant flux from the retroreflector by the optical receiver when the retroreflector is within the field of view of the optical emitting source; records a time of receiving the incident radiant flux; determines a rotational speed of the rotating component based on the recorded time; determines whether the rotational speed is within a predetermined range; and selectively changes a state of the engine when the rotational speed is outside of the predetermined range.

Abstract: A system for preventing abnormal fan blade deflection or fan flutter includes an optical emitting source, an optical receiver, and a retroreflector for attachment to a fan blade of an engine. The system emits radiant flux from the optical emitting source towards the retroreflector when the engine is operating; receives an incident radiant flux from the retroreflector by the optical receiver; determines a deflection value of the fan blade based on the incident radiant flux received by the optical receiver; determines whether the deflection value is greater than or equal to a threshold for deflection of the fan blade to identify abnormal fan blade deflection or fan flutter; and selectively changes a state of the engine when abnormal fan blade deflection or fan flutter is identified.

Abstract: A general method to persuade more blackjack players to place side wagers is disclosed. This method can be applied to improve a variety of blackjack games and side wagers games. Placing a side wager of this method: (a) always activate one or more blackjack rule enhancements that increase the statistical rate of return on the player's blackjack wager, (b) never creates or activates any blackjack rule that could reduce the statistical rate of return on the player's blackjack wager, and (c) always activates a proposition game that is unrelated to any above rule enhancement. A novel benefit of this invention is the player's perception of a free blackjack rule enhancement upon placing a side wager. This perceived free rule enhancement will persuade more players to place side wagers, thus increasing player enjoyment and casino revenues. Relative to this invention, a side wager is defined as an optional wager placed by a player prior to beginning the blackjack game.

Abstract: Switchable retroreflector devices that are modulated via electrowetting. The devices include an electrically-conductive polar fluid and a non-polar fluid that is immiscible with the polar fluid. The polar and the non-polar fluids differ in at least one optical property. The fluids are contained in a fluid vessel, or an array of fluid vessels. The fluids are at least partially viewable. A voltage source is configured to selectively apply an electromechanical force to the polar fluid causing repositioning and/or geometrical change of the fluids such that retroreflection in created, or suppressed, by optical refraction or by optical attenuation.

Abstract: A poker-type game capable of providing a dealer with an initial advantage and a player with a subsequent advantage. From a predetermined number of cards, a dealer is assigned an initial hand having a greater poker value than an initial hand assigned to a player. Subsequently, a dealer receives a number of cards to complete the dealer's hand, and the player receives a number of cards to complete the player's hand, wherein a predetermined poker advantage is conveyed to the predetermined number of cards to complete the player's hand.
