Abstract: Embodiments of the present invention adapt interconnect systems to apply automated rules and analytics to the Authentication, Authorization, and Accounting (“AAA”) messages between providers that are handled by the interconnect system. The automated rules and analytics interpret or convert the administrative messages into a measure of technical performance of the visited network in relation to a corresponding home network provider. As part of this process, the system establishes a procedure that matches messages involving a device to be related and produces a data structure and corresponding data that is stored and reflects the performance or other salient data points. The structure of the data is set of extracted and calculated data that is derived from the messages and is assembled to reflect operation at the level of each administrative messaging session, involving a request to the home network provider to join a visited network.

Abstract: An image sensor may include adaptive filtering circuitry that is used to correct for row noise. In one example, the image sensor may include a single reference pixel or a column of reference pixels that are shielded from incident light. The adaptive filtering circuitry may estimate row noise based on data from the reference pixel(s). Row noise correction circuitry may then subtract the estimated row noise from imaging pixel outputs to correct for row noise. If the row noise is dominated by supply noise, the reference pixels may be omitted entirely and the adaptive filtering circuitry may estimate row noise based only on the power supply voltage. The adaptive filtering circuitry may undergo a training phase to optimize coefficients for the adaptive filtering circuitry.
