5G Cellular User Equipment: From Theory to Practical Hardware Design

Abstract: Research and development on the next generation wireless systems, namely 5G, has experienced explosive growth in recent years. In the physical layer, the massive multiple-input-multiple-output (MIMO) technique and the use of high GHz frequency bands are two promising trends for adoption. Millimeter-wave (mmWave) bands, such as 28, 38, 64, and 71 GHz, which were previously considered not suitable for commercial cellular networks, will play an important role in 5G. Currently, most 5G research deals with the algorithms and implementations of modulation and coding schemes, new spatial signal processing technologies, new spectrum opportunities, channel modeling, 5G proof of concept systems, and other system-level enabling technologies. In this paper, we first investigate the contemporary wireless user equipment (UE) hardware design, and unveil the critical 5G UE hardware design constraints on circuits and systems. On top of the said investigation and design tradeoff analysis, a new, highly reconfigurable system architecture for 5G cellular user equipment, namely distributed phased arrays based MIMO (DPA-MIMO) is proposed. Finally, the link budget calculation and data throughput numerical results are presented for the evaluation of the proposed architecture.

Systems and Methods for Tracking the Status and Usage Information of a Wireless Power Transmission System

Abstract: Disclosed here are methods and systems to generate and distribute information about the status and usage of a wireless power transmission system. Specifically, the present disclosure may describe a process to generate information through various software running in different components of the wireless power transmission system. Additionally, the disclosure may also include a wireless power transmission system architecture which may include components, such as a remote information service, a remote information service manager, a remote information service database, one or more authorized computing devices, and a plurality of system information generators. System information generator may refer to components, such as wireless power transmitters, computing devices/non computing devices (coupled with power receiver devices), a system management service, and distributed system database. The aforementioned components within the wireless power transmission system may be used to automatically and autonomously generate, store, transmit, and distribute system status, usage, and statistics or metrics information in order to be edited or reported by authorized and authenticated users. The information may also be used to increase the accuracy of strategic marketing, sales focus, to alert customer service of system problems and performance issues, and for billing end users.

The Datacycle architecture

Abstract: A database system is, by one definition [4], "a system whose overall purpose is to maintain information and to make that information available on demand." Database systems have evolved as part of a response to the desire to separate concerns. That is, the "application" should be responsible for manipulation of information and for its presentation to a user, and the "database system" should perform application-independent data management operations. A true separation, however, is difficult to achieve in practice. Often, the internal data structures and physical placement of data within the database system are optimized to achieve efficient performance for those queries known to be critical for the target application. The data schema itself may also reflect performance concerns. For particularly demanding applications, such as information filtering, database management may be completely customized to meet the needs of the application and even embedded within the application itself. The Datacycle TM architecture [2, 10] is a radical approach to database management. It attempts to achieve a full separation of concerns between the needs of many applications and the database management system supporting those needs, even for applications with unusually high demands for flexibility in access to data and for performance. In the Datacycle architecture, the contents of the entire database are broadcast cyclically over high-bandwidth communication facilities to multiple very large-scale integration (VLSI) data filters that perform complex associative search operations in parallel. The cyclic broadcasting and hardware filtering of information allow a different set of technology trade-offs affecting system architecture, functionality, and performance. The result is a unique combination of functionality and performance to support complex information management applications: • As in most database systems based on the relational model [3], the interface between the

Hive: distributed agents for networking things

Abstract: Hive is a distributed agent platform, a decentralized system for building applications by networking local system resources. This paper presents the architecture of Hive, concentrating on the idea of an "ecology of distributed agents" and its implementation in a practical Java-based system. Hive provides ad-hoc agent interaction, ontologies of agent capabilities, mobile agents and a graphical interface to the distributed system. We are applying Hive to the problems of networking "Things That Think" (TTT), putting computation and communication in everyday places, such as your shoes, your kitchen or your own body. TTT shares the challenges and potentials of ubiquitous computing and embedded network applications. We have found that the flexibility of a distributed agent architecture is well suited for this application domain, enabling us to easily build applications and to reconfigure our systems on-the-fly. Hive enables us to make our environment and network more alive.

Computer system architecture and method providing operating-system independent virus-, hacker-, and cyber-terror-immune processing environments

Abstract: Information appliance, computing device, or other processor or microprocessor based device or system provides security and anti-viral, anti-hacker, and anti-cyber terror features, and can automatically create multiple sequentially or concurrently and intermittently isolated and/or restricted computing environments to prevent viruses, malicious or other computer hacking, computer or device corruption and failure by using these computing environments in conjunction with restricted and controlled methods of moving and copying data, combined with a process that destroys malicious code located in computing environments and data stores.
