  • Patent number: 8765808
    Abstract: The NSAID, sulindac and/or its metabolites and derivatives, in combination with hydrogen peroxide or another oxidizing agent, such as arsenic trioxide that generates reactive oxygen species (ROS), significantly enhances the killing of cancer cells. This effect occurs at concentrations of each compound that individually have little or no activity directed against cancer cells. A skin cream has been developed and used to treat skin cancer and precancerous skin growths that effectively removes the lesions with no effect on surrounding normal skin.

  • Patent number: 8768806
    Abstract: The present embodiments are provided to facilitate the automatic trading of spreads in a fast and accurate manner. One or more market data feeds that contain market information for tradeable objects are received at an exchange. A spread data feed is generated in response to the market data feeds and from one or more spread setting parameters, which can be entered by a user. The spread data feed is preferably displayed in a spread window as bid and ask quantities associated with an axis or scale of prices. The user can enter orders in the spread window and the legs will be automatically worked to achieve, or attempt to achieve, the spread. In addition, other tools disclosed herein may be utilized to assist the user in making such trades.

  • Patent number: 8768618
    Abstract: Methods and systems for determining a location of a mobile device using a multi-modal Kalman filter are described. According to an example method, a mobile device may maintain multiple approximations of a location of a mobile device. Each approximation includes an estimated geographic location of the mobile device that is determined by filtering a respective subset of location estimates received by the mobile device using a respective Kalman filter, and one of the multiple approximations is designated as an active approximation. The method also involves receiving data indicating an estimate of a geographic location of the mobile device and, based on a distance between the estimate of the geographic location and a given approximation of the multiple approximations, updating the given approximation using the estimate of the geographic location. Additionally, the method involves providing for display a visual indication of an estimated geographic location associated with the active approximation.

  • Patent number: 8769514
    Abstract: A dynamic race detection system is provided that detects race conditions in code that executes concurrently in a computer system. The dynamic race detection system uses a modified software transactional memory (STM) system to detect race conditions. A compiler converts portions of the code that are not configured to operate with the STM system into pseudo STM code that operates with the STM system. The dynamic race detection system detects race conditions in response to either a pseudo STM transaction in the pseudo STM code failing to validate when executed or an actual STM transaction failing to validate when executed because of conflict with a concurrent pseudo STM transaction.

  • Patent number: 8764848
    Abstract: Devices, delivery systems and delivery techniques for an occlusion device for the closure of physical anomalies, such as an atrial septal defect, a patent foramen ovale (PFO), and other septal and vascular defects are described. The devices, delivery systems and delivery techniques relate particularly to, but are not limited to, a patent foramen ovale (PFO) occluder made from a polymer tube. Specifically, a petal-shaped occluder with a catch system is provided within a delivery sheath. In certain embodiments, the delivery system includes a first securement system for securing a first end of the occluder and a second securement system for securing a second end of the occluder to a delivery catheter and a delivery wire contained in the delivery system. The securement enable the deployment (and retrieval) of the device.
