Abstract: An input signal is sampled at a current sampling phase by a sampler device of a receiver device. The sampled input signal is equalized by an adaptive equalizer of the receiver device. One or more parameters of the adaptive equalizer are adapted, based on the equalized input signal, under one or more adaptation constraints. Phase gradient information indicative of an offset of the current sampling phase from an optimal sampling phase is determined, and the one or more adaptation constraints of the adaptive equalizer are updated based on the phase gradient information to move the current sampling phase towards the optimal sampling phase.

Abstract: In some implementations, a computing device can present accessory state information. For example, the computing device can receive accessory state information from various accessories and present status items representing the current state of the accessories. The status items can be prioritized according to classifications assigned to accessories and/or accessory state information. The status items can be filtered based on a role assigned to the user of the computing device. Additional implementations and details are described in the paragraphs that follow.

Abstract: Participants as requestors using a requesting network element request one or more tokenization processors to generate tokens that represent a sanitized version of data such that the resultant tokens are amenable to comparison across participants. As circumstances warrant, one or more such tokens can be submitted to the tokenization processor(s) to privately retrieve the original data. Role-based access control scope parameters and tokenization processor-specific tokenization processor secrets can be embedded into reversible tokens that remain invariant under updating of the tokenization processor secrets across tokenization processors.

Abstract: The system is a scalable, flexible, and extensible platform for building, deploying, and managing distributed applications that interact with multiple blockchain technologies. The system implements well-defined and well-managed microservices to encapsulate functionality, isolate sensitive data, enable responsive and efficient scaling, and provide a framework for future improvements and support for future blockchain technologies. The system in one embodiment uses an event-driven architecture to construct fast, responsive systems, but still provide support for alternate modes of operation. The system exposes high-level abstractions of the foundational elements of distributed applications in a powerful, well-understood programming environment to simplify development of extensions, adapters, and applications.
