  • Patent number: 7837099
    Abstract: A loyalty program business model includes entering into an agreement with loyalty program partners and agreeing on exchange rates between a variety of loyalty unit types. Partner accrual records (PAR's) arc accepted from the loyalty program partners related to the business activity of related loyalty program members. Loyalty units credits are calculated for a member from data obtained in the step of accepting. A partner loyalty account balance is updated according to the standardized loyalty unit debit obtained in the step of calculating. Then an invoice can be billed to a partner according to the partner loyalty account balance.

  • Patent number: 7556086
    Abstract: Device for enhancing cooling of electronic circuit components that is substantially or fully independent of orientation. A thin profile thermosyphon heat spreader mounted to an electronics package comprises a central evaporator in hydraulic communication with a peripheral condenser, both at least partially filled with liquid coolant. A very high effective thermal conductivity results. Performance is optimized by keeping the evaporator substantially full at all orientations while leaving a void for accumulation of vapor in the condenser. A cover plate and a parallel base plate of generally similar dimension form the evaporator and condenser. Optionally, an opening in the base plate is sealed against the electronics package and places the heat-dissipating component in direct contact with the liquid coolant. Alternatively, the base plate may be formed with the electronics package from a single piece of material. A boiling enhancement structure is provided in the evaporator to encourage vapor bubble nucleation.
