Abstract: A wireless charging system is configured to charge one or more receiver devices simultaneously. The wireless charging system includes multiple coils that may be driven independently based on a feedback system with one or more feedback channels. One of the feedback channels may be demodulated communication signals from the one or more receiver devices. The demodulation may be performed by a communication demodulation circuit with configurable gain. The demodulated communication signals are processed for error correction at a bit level and a packet level, which improves accuracy despite presence of multiple receiver devices and noisy conditions.

Abstract: A computer-implemented method according to one embodiment includes outputting, from a requester system to a server system, a request signature. The request signature requests at least one parameter of a function specified in the request signature. The method further includes receiving a first response signature from the server system and identifying within the first response signature a parameter. The specified function is applied to the identified parameter for determining whether the parameter is valid. In response to a determination that the identified parameter of the first response signature is invalid, a location and/or an identity of the identified parameter is marked in a copy of the first response signature. The method further includes using a functional topology of the requester system to trace the identified parameter determined to be invalid to a valid parameter, and outputting a second response signature that includes the marked-up copy of the first response signature.
