  • Patent number: 8321328
    Abstract: Systems and methods are provided for providing a credit default futures market. A system providing the credit default futures market includes a processor, memory and an interface. The interface is configured to display credit default futures contracts that subscribe to a set of standard terms and conditions. The processor is configured to settle certain credit futures contracts in kind and other in cash, depending on, at least in part, the maturity date of the futures contract. A method is presented for electronically clearing and settling probability of default futures contracts.

  • Patent number: 7341521
    Abstract: A joystick control system includes a first pair and a second pair of fluid enclosed resilient tubes with each pair of tubes having generally parallel spaced pressure sensing portions confined within a support housing with one pair of sensing portions disposed perpendicular to the other pair of sensing portions. A control stick extends between the spaced sensing portions of both pairs of tubes and is supported for slight lateral or universal tilting movement. Each pair of tubes is connected to a corresponding sensing transducer which varies electrical output signals according to the pressure applied to the sensing portions of the tubes by the control stick.

  • Patent number: 6799549
    Abstract: An internal combustion rotary engine which includes a housing encased rotor having: cam actuated inwardly and outwardly extending vanes, a combustion chamber communicating with a fluid inlet port to the vanes within the housing, and an exhaust chamber communicating with the fluid outlet port from the vanes of the housing, air and fuel injectors associated with the combustion chamber for delivery of an air and fuel mixture to the combustion chamber, and igniter means associated with the combustion chamber for igniting air and fuel mixture within that chamber. Controls are provided to properly control the sequence of air and fuel injection, fuel ignition and exhaust valve opening and closing during operation of the engine to provide simpler and more economical rotary engine.

  • Patent number: 6439635
    Abstract: The present invention 10 discloses a hydraulic seat lift 20 for an all-terrain vehicle 26 having the driver's seat 16 located on a top portion of a platform 20 and the superior end of the hydraulic scissor-lift mechanism 44 fastened to a side portion of the platform 20 in a manner that would raise the driver seated on the platform as the hydraulic scissor-lift mechanism 44 is extended and would lower the operator as it retracts. The hydraulic scissor-lift mechanism comprises two hydraulically powered scissor-lifts 44 located on opposing sides of the seat lift platform 20 with each scissor-lift comprising inversely paired diagonal cross-members that are medially connected to one another with the distal ends of each pair of cross-members pivotably connected to the distal ends of the next pair of cross-members which can be repeated to form a vertically stacked series of interconnected cross-members.

  • Patent number: 4590474
    Abstract: A street crossing signal device for blind pedestrians. The device indicates the directions of pedestrian crosswalks at an intersection, so that the blind person can orient himself in a desired direction for crossing the street at one of the crosswalks, and provides a signal to that person when that crosswalk is safe for pedestrian crossing. The device comprises a pair of rigid hand rails secured to a post at the corner of the intersection, each hand rail having at least a portion thereof oriented in the direction of a corresponding crosswalk. The device further comprises a vibrator means which is secured within each hand rail. The vibrator means when actuated causes its associated hand rail to vibrate. Also provided is means to mechanically isolate each hand rail from the post so that vibrations from the hand rails are not transmitted to the post.
