Abstract: A transformer apparatus and a transformer shielding method are provided for shielding external electronic noises and protecting against erosion. The transformer apparatus comprises a toroidal core, a primary winding, a secondary winding, a protection tape, a metal foil, and an UL tube. The primary winding and the secondary winding are wound around the toroidal core at opposite side to each other. The protection tape is wrapped around the primary winding and the secondary winding. The metal foil encloses the protection tape. The UL tube enfolds the metal foil. The transformer shielding method comprises wrapping a primary winding and a secondary winding of the transformer apparatus by a protection tape, enclosing the protection tape by a metal foil, and enfolding the metal foil by an UL tube.

Abstract: Methods and systems for providing unified analytics across a distributed computing services infrastructure are disclosed. Embodiments include providing an application identifier for an application created by a developer and, during an execution of the application, collecting and storing analytic data with an association with the application identifier and an authenticated developer identifier. Other embodiments may include collecting and storing analytic data with the association further including an authenticated user identifier and/or a device identifier for a device of a user-defined group or mesh. Access mechanisms, report generation, and billing based on the analytic data and associated application identifier are also disclosed. The disclosed methods and systems allow for unified reporting and correlation of analytic data across multiple services of a distributed computing services infrastructure.
