  • Patent number: 8645002
    Abstract: The present invention provides a system and method for facilitating and monitoring provisioning of wireless communication devices. Wireless devices are provided to an end user in an unconfigured state, capable of being configured for operation using one or more communication protocols. Upon receipt and validation of a provisioning request by the wireless device, for example by a server, the wireless device is securely provisioned for operation with a wireless service provider. Provisioning activities are monitored and information is generated in response to provisioning events, for example via a database. Portions of the information are made available to one or more wireless service providers or parties providing enabling technology of the wireless device. Such reports may be used to facilitate revenue agreements between various parties involved in providing and servicing the wireless device.

  • Publication number: 20140006109
    Abstract: The present invention relates to systems and methods for calculating a segment's sensitivity to price changes. A histogram distribution is generated for transaction frequency by price as the initial part of the sensitivity analysis. The shape of this histogram may be used to extrapolate a sensitivity measure. This can be done in two distinct ways: statistical regression or slope approximation. For statistical regression, the inverse of the cumulative distribution function is first calculated. The slope of this function is determined to be the sensitivity; the steeper the curve the more sensitive the segment is to price changes. The second technique approximates the slope of the right hand side of the histogram in order to determine sensitivity.

  • Patent number: 8301487
    Abstract: A power and risk score calibrator is provided, which receives quantitative power and risk scores for each quantitative segment, and receives qualitative power and risk scores for each qualitative segment. The qualitative segment and the qualitative power and risk scores are defined by a user. The system generates consolidated segments. Then consolidated power and risk scores for each of the consolidated segments are generated, respectively. The gaps between the qualitative power and risk scores and the consolidated power and risk scores are reconciled. From these reconciliations, adjustment factors are generated, which are applied by pricing power and risk value calibrators. The system may also perform a drill down to explain the gap between the qualitative scores and the consolidated scores.
