Externally initiated application session endpoint migration
In storage networks (e.g., SAN and NAS), various reasons can arise for migrating an application layer communication session endpoint to a different host. To achieve scalability and robustness, the migration can be enacted externally and carried out at a middlebox at the transport layer. When a migration is triggered to migrate an application layer communication session endpoint from a host A to a host B, the middlebox coordinates network address translation with a transport protocol reset mechanism to switch the connection to host B and close the connection on host A with minimal disruption to the non-migrating application layer communication session endpoint using the connection. At the application layer, the non-migrating application layer communication session endpoint will initiate a new connection in response to detecting the reset, and retry any operation that was aborted as a result of the connection switch. |

Blockchain identity management system based on public identities ledger
The invention describes an identity management system (IDMS) based on the concept of peer-to-peer protocols and the public identities ledger. The system manages digital identities, which are digital objects that contain attributes used for the identification of persons and other entities in an IT system and for making identity claims. The identity objects are encoded and cryptographically encapsulated. Identity management protocols include the creation of identities, the validation of their binding to real-world entities, and their secure and reliable storage, protection, distribution, verification, updates, and use. The identities are included in a specially constructed global, distributed, append-only public identities ledger. They are forward- and backward-linked using the mechanism of digital signatures. The linking of objects and their chaining in the ledger is based on and reflect their mutual validation relationships. The identities of individual members are organized in the form of linked structures called the personal identities chains. Identities of groups of users that validated identities of other users in a group are organized in community identities chains. The ledger and its chains support accurate and reliable validation of identities by other members of the system and by application services providers without the assistance of third parties. The ledger designed in this invention may be either permissioned or unpermissioned. Permissioned ledgers have special entities, called BIX Security Policy Providers, which validate the binding of digital identities to real-world entities based on the rules of a given security policy. In unpermissioned ledgers, community members mutually validate their identities. The identity management system provides security, privacy, and anonymity for digital identities and satisfies the requirements for decentralized, anonymous identities management systems. |

Adaptive ISO-gain pre-distortion for an RF power amplifier operating in envelope tracking
The output of a Radio Frequency (RF) Power Amplifier (PA) is sampled and down-converted, and the amplitude envelope of the baseband feedback signal is extracted. This is compared to the envelope of a transmission signal, and the envelope tracking modulation of the RF PA supply voltage is adaptively pre-distorted to achieve a constant ISO-Gain (and phase) in the RF PA.

Since the gains are calculated from a feedback signal, the pre-distortion may be recalculated at event triggers, such as an RF frequency change. |

Antenna device
A variable resonant circuit is inserted between a feeding point of a radiating element and a ground conductor. When the variable resonant circuit is not inserted, an input impedance of the radiating element is lower than about 50Ω and capacitive in a first low frequency band, lower than about 50Ω and inductive in a second low frequency band, and close to about 50Ω in a high frequency band. When the variable resonant circuit exhibits a first resonance characteristic, the variable resonant circuit is inductive in the first low frequency band, and its impedance in the high frequency band is higher than that in the first low frequency band. When the variable resonant circuit exhibits a second resonance characteristic, the variable resonant circuit is capacitive in the second low frequency band, and its impedance in the high frequency band is higher than that in the second low frequency band. |

Galvanically separated non-interacting antenna sector apparatus and methods
An antenna apparatus with isolated non-interactive sectors and methods operating and forming the same. In one embodiment, an antenna with a radiative element comprising a planar layer with multiple sectors is disclosed. The sectors are configured to be interactive or non-interactive.
