Exemplary conversion systems can be enabled/disabled such that one or more can operate simultaneously based on, e.g., subframe timing of received signal, predetermined schedule, power or energy of s, availability of reference signals, channel coherence time, and apparatus energy consumption. Further, exemplary methods and computer-readable media can be provided embodying one or more procedures the apparatus is configured to perform.

Switched analog-digital architecture for wireless antenna arrays and methods for use thereof

The basic idea of this invention is to send one or more cubesats into orbit, each equipped with a hardware security module. Users would send their transaction to the cubesats which would collect them into blocks, sign them, and send (bounce) them back to earth (and to one another). Bounce Blockchain provides scalability through sharding (transactions will be partitioned over cubesats). Because modern hardware security modules are tamper-resistant (become inoperable if tampered with) or tamper-responsive (erase their keys if tampered with), take their keys from physical processes, and have been validated, socio-technical protocols can ensure that it is infeasible to forge the identity of a hardware security module in a cubesat with another cubesat. If, however, some cubesats are destroyed, the blockchain will continue to execute correctly though some transactions will be lost. New cubesats can be sent up in short order as they are quite cheap to launch. If, in spite of these assurances, some cubesats fail traitorously, the blockchain can survive through algorithms similar to Practical Byzantine Fault Tolerance techniques.

This invention introduces a new paradigm for outsourcing the transaction processing backend of a multi-client database application to an untrusted service provider. Specifically, the invention enables untrusted service providers to support transaction serialization, backup and recovery for clients, with full data confidentiality and correctness. Moreover, providers learn nothing about transactions (except their size and timing), thus achieving read and write access pattern privacy.
