  • System for providing a correlation index
    Patent number: 8606682
    Abstract: A system includes a memory and a processor communicatively coupled to the memory. The memory stores a correlation index that is based at least in part on a portfolio of index options, a plurality of stock options, and a plurality of deltas computed using a plurality of constant flat implied volatilities. The processor determines a value of the correlation index by selecting a plurality of strike prices for each of the index and stock options, computing a constant flat implied volatility for an index and a plurality of stocks on a first date, and computing the plurality of deltas using the plurality of constant flat implied volatilities.

  • Light-emitting devices including a nonperiodic pattern
    Patent number: 7915679
    Abstract: Light-emitting devices, and related components, systems and methods are disclosed. In some embodiments, the light-emitting devices include a multi-layer stack of materials. The stack of materials includes a light-generating region and a first layer supported by the light-generating region. The surface of the first layer is configured so that light generated by the light-generating region can emerge from the light-emitting device via the surface of the first layer. The surface has a dielectric function that varies spatially according to a nonperiodic pattern.
