Abstract: During operation, an electronic device monitors data associated with different power states received from another electronic device via an interface circuit. Using the monitored data, the electronic device calculates a time duration that the other electronic device is in an active operating mode. Moreover, the electronic device determines power states of the other electronic device based on the calculated time duration and/or a time duration between times when data is received. Next, the electronic device calculates the power-consumption history of the other electronic device based on the determined power states and at least a model of power consumption in different power states of the other electronic device. By calculating the power-consumption history of the other electronic device, the electronic device may significantly improve the accuracy of a power-usage model for the other electronic device.

Abstract: A method and system for formatting characteristic CRT information into a standardized format to provide a dynamic CRT characteristic profile to enhance presently used methods of recalibrating CRTs is disclosed. Present CRT parameters are measured and combined with previously acquired calibration parameters in order to create updated characteristic information for the profile. The characteristic information includes the CRT color gamut, the white and black point of the CRT and the gamma of the CRT. In addition, ambient lighting conditions may be included in the profile. This characteristic information is stored in a CRT characterization profile in a standardized format. The profile is updated whenever the CRT is recalibrated or whenever the operating conditions of the CRT are changed. Further, the profile may be employed to recalibrate a destination CRT based on a source CRT's profile.
