  • User interface enabling approval/disappoval of revised contract performance indicators
    Patent number: 8533027
    Abstract: A user interface and processes are provided to monitor contracts for the delivery of products and/or services to different customers. The user interface provides a comprehensive visual display such that a user can view multiple contracts and a variety of performance information for each contract. The user interface also enables a user to update performance indicators for a contract and to identify contracts that require heightened scrutiny or action to mitigate current problems or potential issues.

  • Sigma-delta modulator including truncation and applications thereof
    Patent number: 7969341
    Abstract: A multi-stage sigma-delta modulator including bit truncation between stages. The bit truncation reduces the number of bits that must be processed in subsequent stages and thus allows for faster response times. In some embodiments, the gain of a feedback loop is selected to compensate for the bit truncation such that the sigma-delta modulator operates in a stable state.
