  • 32801.从模拟多线电话建立听觉-触觉模型界面提示

    [计算机、通信和其他电子设备制造业] [2014-04-03]

     This multi-line telephone was used as a model for a trade study comparison of two interfaces: a touchscreen interface (iPad) versus a pressure-sensitive strain gauge button interface (Phidget USB interface controllers). The experiment and its results are detailed in the authors' AES 133rd convention paper; Multimodal Information Management: Evaluation of Auditory and Haptic Cues for NextGen Communication Dispays;. This Engineering Brief describes how the interface logic, visual indications, and auditory cues of the original telephone were synthesized using MAX/MSP, including the logic for line selection, line hold, and priority line activation.

  • 32802.机场移动航空通信系统干扰对机场的辐射模式特性的影响

    [铁路、船舶、航空航天和其他运输设备制造业,计算机、通信和其他电子设备制造业] [2014-04-03]

    In this study, the cumulative interference power distribution at low earth orbit from AeroMACS transmitters at the 497 major airports in the contiguous United States was simulated with the Visualyse Professional software. The dependence of the interference power on the number of antenna beams per airport, gain patterns, and beam direction orientations was simulated. As a function of these parameters, the simulation results are presented in terms of the limitations on transmitter power required to maintain the cumulative interference power under the established threshold.

  • 32803.支持实时仿真空间链接的硬件和软件集成

    [计算机、通信和其他电子设备制造业,信息传输、软件和信息技术服务业] [2014-04-01]

    Prior to operational use, communications hardware and software must be thoroughly tested and verified. In space-link communications, field testing equipment can be prohibitively expensive and cannot test to non-ideal situations. In this paper, we show how software and hardware emulation tools can be used to accurately model the characteristics of a satellite communication channel in a lab environment. We describe some of the challenges associated with developing an emulation lab and present results to demonstrate the channel modeling. We then show how network emulation software can be used to extend a hardware emulation model without requiring additional network and channel simulation hardware.

  • 32804.智能手机辅助快速通信和控制系统全面的系统测试计划

    [信息传输、软件和信息技术服务业,计算机、通信和其他电子设备制造业] [2014-04-01]

    This thesis contains a test plan and implementation of the plan for the SPARCCS system as well as a formal technical analysis of the system to ensure the proper operation, verification, and validation of the initial SPARCCS functional system. The SPARCCS system and the various wireless technologies upon which the system operates are thoroughly tested in various field and live settings to simulate real-world military and emergency services operations. The tests are designed to determine the optimal configurations of SPARCCS as well as the optimal wireless technologies to be used with SPARCCS for various operational situations.

  • 32805.连接操作和战略通信架构:集成小型无人机系统作为机载战术中继通信垂直节点

    [计算机、通信和其他电子设备制造业,信息传输、软件和信息技术服务业] [2014-03-31]

    Through the efforts of this thesis, the goal is to extend and enhance beyond line of sight (BLOS) and on-the-move communications at the small unit level. The findings provide face validation that Small-UAS equipped with a communication payload can provide these services that enhance voice transmissions, and thus, enable TCP/IP data transfer in communication degraded environments without interfering with the Small-UAS primary ISR function or airworthiness. Future efforts in this line of inquiry may also inform the use of multiple Small-UAS to extend the network and autonomous operations, and perhaps, eliminate the requirement for a ground Small-UAS operator.

  • 32806.集成无人机行动的控制和无负载通信链路

    [计算机、通信和其他电子设备制造业,信息传输、软件和信息技术服务业] [2014-03-31]

    Technology for unmanned aircraft has advanced so rapidly in recent years that many new applications to public and commercial use are being proposed and implemented. In many countries, emphasis is now being placed on developing the means to allow unmanned aircraft to operate within non-segregated airspace along with commercial, cargo and other piloted and passenger-carrying aircraft.This paper provides a description of the CNPC system, an overview of NASA's CNPC project, and current results in technology assessment, air-ground propagation characterization, and supporting system studies and analyses will be presented.

  • 32808.双频(无线电/光学)航天器通信的并行系统工程和风险降低

    [信息传输、软件和信息技术服务业,计算机、通信和其他电子设备制造业,铁路、船舶、航空航天和其他运输设备制造业] [2014-03-31]

    This paper describes a system engineering approach to examining the potential for combining elements of a deep-space RF and optical communications payload, for the purpose of reducing the size, weight and power burden on the spacecraft and the mission. Figures of merit and analytical methodologies are discussed to conduct trade studies, and several potential technology integration strategies are presented. Finally, the NASA Integrated Radio and Optical Communications (iROC) project is described, which directly addresses the combined RF and optical approach.

  • 32809.月球通信卫星和服务器的设计和实现以应对2012年SISO攻击波

    [计算机、通信和其他电子设备制造业,铁路、船舶、航空航天和其他运输设备制造业,信息传输、软件和信息技术服务业] [2014-03-31]

    Last year, the Simulation Interoperability Standards Organization (SISO) inaugurated the now annual High Level Architecture (HLA) Smackdown at the Spring Simulation Interoperability Workshop (SIW). A primary objective of the Smackdown event is to provide college students with hands-on experience in the High Level Architecture (HLA). The University of Alabama in Huntsville (UAHuntsville) fielded teams in 2011 and 2012.This paper concentrates on the first two federates by describing the functions, algorithms, the modular FOM, experiences, lessons learned and recommendations for future Smackdown events.
