摘要:
A system and method for creating a limited risk derivative based on a realized variance of an underlying equity is disclosed. In one implementation, a limited risk derivative product includes a capped value for a statistical property reflecting a variance of the underlying equity is calculated based on a pari-mutuel action. The capped value comprises a dynamic value and a cap. The dynamic value reflects an average volatility of prices returns of the underlying equity over a predefined period of time and the cap reflects a maximum value of the dynamic value. The limited risk derivative product additionally includes an average of a summation of each squared daily return of the underlying equity included in the value for the statistical property reflecting the variance of the underlying equity.
摘要:
Methods and systems for creating and trading derivative contracts based on a statistical property reflecting a variance of an underlying asset are disclosed. Typically, an underlying asset is chosen to be a base of a variance derivative and a processor calculates a value of the statistical property reflecting an average volatility of price returns of the underlying asset over a predefined period. A trading facility display device coupled to a trading platform then displays the variance derivative based on the value of the statistical property reflecting the volatility of the underlying asset and the trading facility transmits variance derivative quotes from liquidity providers over at least one dissemination network.

摘要:
A ball valve assembly for use as a control valve for controlling the flow of gas through a continuous stroke pneumatic tool. The valving element is generally spherical and non-magnetizable. The generally spherical valving element is loosely confined between two concave generally conical surfaces, which are provided on valve seat members. The concave generally conical surfaces are opposed to one another to define a valve chamber therebetween. Sufficient clearance is provided so the generally spherical valving element is free to roll and tumble as it moves in the valve chamber between the concave generally conical surfaces. This allows the ball valve assembly to be self purging of excess lubricant, dust, and the like. Wear is distributed over the entire generally spherical surface of the valving element. The loose confinement is also sufficient to provide a relatively large cross-section of gas passageway through the control valve assembly. The two valve seat members are suitably ported to permit the ball valve assembly to be used as a drop-in replacement for prior pneumatic tool control valves.
摘要:
A system for moving an elongate medical device has at least one drive element for engaging and moving an elongate medical device. Various embodiments provide for moving the separate inner and outer elements of a telescoping medical device. Some systems also provide for the rotation of a rotatable distal element on a rotatable medical device or the rotation of extension element in a telescoping medical device.
摘要:
An interface for remotely controlling medical device in a patients body provides a two dimensional display of a three dimensional image of the operating region, and allows the user to select the orientation of distal end of the medical device on the display and then operate a navigation system to cause the distal end of the medical device to assume the selected orientation.
摘要:
An interlock for two circuit breakers, with the circuit breakers configured in the same electrical circuit and with each circuit breaker having a cross bar and contact assembly. The interlock comprises a pivot pin mounted a spaced distance from the two circuit breakers. An interlock yoke having two ends, with a notch proximate each end of the yoke and the yoke is coupled to the pivot pin. A first operator rod having a first end is configured to engage the cross bar and contact assembly of one circuit breaker and has a second end configured to engage the notch of the yoke. A second operator rod having a first end is configured to engage the cross bar and contact assembly of the other circuit breaker and has a second end configured to engage the notch of the yoke. When one operator rod is moved by the cross bar and contact assembly of one circuit breaker, that operator rod pivots the yoke, causing the other operator rod to block the operation of the other circuit breaker.
摘要:
An aircraft cockpit display arrangement having a primary instrument display region for positioning in front of at least one pilot. The primary instrument display region has a wide screen format panel display and duplicated redundant display drive electronics configured to present both primary flight information and navigational display information on the same screen.
