IRIG-106 CHAPTER 10 RECORDER WITH BUILT-IN DATA FILTERING MECHANISM

Berdugo, Albert, Natale, Louis 10 1900 (has links)
ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / Sixteen years ago, RCC added Chapter 8 to the IRIG-106 standard for the acquisition of 100% MIL-STD-1553 data from up to eight buses for recording and/or transmission. In the past 5 years, the RCC recording committee added Chapter 10 to the IRIG-106 standard for acquisition of 100% data from PCM, MIL-STD-1553 busses, Video, ARINC-429, Ethernet, IEEE-1394, and others. IRIG-106 Chapter 10 recorder suppliers have further developed customer-specific interfaces to meet additional customer needs. These needs have included unique radar and avionic bus interfaces such as F-16 Fibre Channel, F-35 Fibre Channel, F-22 FOTR, and others. IRIG-106 Chapter 8 and Chapter 10 have provided major challenges to the user community when the acquired avionics bus data included data that must be filtered and never leave the test platform via TM or recording media. The preferred method of filtering data to ensure that it is never recorded or transmitted is to do so at the interface level with the avionic busses. This paper describes the data filtering used on the F-22 Program for the MIL-STD-1553 buses and the FOTR bus as part of the IRIG-106 Chapter 10 Multiplexer/Recorder System. This filtering method blocks selected data at the interface level prior to being transferred over the system bus to the media(s). Additionally, the paper describes the configuration method for defining the data to be blocked and the report generated in order to allow for a second party to verify proper programming of the system.

CONVERTING ASYNCHRONOUS DATA INTO A STANDARD IRIG TELEMETRY FORMAT

Peart, David E., Talbert, Jim 10 1900 (has links)
International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, Nevada / In recent years we have seen an increase in the use of MIL-STD-1553 buses and other asynchronous data sources used in new missile and launcher designs. The application of multiplexed asynchronous buses in missiles and launchers is very common today. With increasing application of asynchronous data sources into very complex systems the need to acquire, analyze, and present one hundred percent of the bus traffic in real time or near real time has become especially important during testing and diagnostic operations. This paper discusses ways of converting asynchronous data, including MIL-STD-1553, into a telemetry format that is suitable for encryption, telemetering, recording, and presenting with Inter Range Instrumentation Group (IRIG) compatible off-the-shelf hardware. The importance of these designs is to provide the capability to conserve data bandwidth and to maximize the use of existing hardware. In addition, this paper will discuss a unique decode and time tagging design that conserves data storage when compared to the methods in IRIG Standard 106-96 and still maintains a very accurate time tag.

MIL-STD-1553 Data Acquisition System

Landry, Michael 11 1900 (has links)
International Telemetering Conference Proceedings / October 30-November 02, 1989 / Town & Country Hotel & Convention Center, San Diego, California / The Range Commanders Council recently added a chapter to IRIG 106-86 which describes a standard for acquisition of MIL-STD-1553 traffic flow. A system has been developed which monitors bus traffic using the format described in the standard for encoding. In addition to bus data, PCM analog channels can be inserted into the telemetry steam. Due to the high bandwidth of the telemetry stream, real-time ground processing of the 1553 data is difficult. Therefore, a limited number of selective measurements taken from the bus traffic are available at fixed positions in the telemetry format for real-time monitoring of critical parameters. A discussion of hardware, software, encoding, and testing will be presented.

CREATING FLOATING POINT VALUES IN MIL-STD-1750A 32 AND 48 BIT FORMATS: ISSUES AND ALGORITHMS

Mitchell, Jeffrey B. 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Experimentation with various routines that create floating point values in MIL-STD-1750A 32 and 48 bit formats has uncovered several flaws that result in loss of precision in approximation and/or incorrect results. This paper will discuss approximation and key computational conditions in the creation of values in these formats, and will describe algorithms that create values correctly and to the closest possible approximation. Test cases for determining behavior of routines of this type will also be supplied.

Influencia da adubação organica sobre a biomassa, o rendimento e a composição do oleo essencial de Achillea millefolium L. - mil folhas

Scheffer, Marianne Christina 21 August 2012 (has links)
Resumo: Foi feito experimento a campo para verificar a influência da adubação orgânica sobre a biomassa, o rendimento e a composição do óleo essencial de Achillea millefolium L. - mil folhas - à qual são atribuídas propriedades hemostáticas, antiespasmódicas, anti inflamatórias, antiprurídicas, analgésicas e antipiréticas. O delineamento experimental utilizado foi blocos ao acaso com cinco repetições. A área onde foi realizado o experimento apresenta as seguintes características: pH - 4,9; fósforo disponível - 2 ppm; potássio - 0,24 meq/100 9 de TFSA; carbono - 4,1 %. Foram testadas cinco doses de adubo orgânico (esterco de gado + palha), quais sejam: zero; 1,0; 2,0; 3,0 e 4,0 kg/m2 , calculados em peso seco. Determinou-se que o adubo orgânico apresentava 1,17 % de nitrogênio, 0,21 % de fósforo e 0,95 % de potássio. Os dados coletados foram biomassa, rendimento de óleo essencial, teores de N P K nas extremidades floridas secas e características químicas do solo. Determinou-se o índice de refração do 61eo essencial extraído; identificou-se, por cromatografia gasosa e espectrometria de massa, os principais compostos e calculou-se o percentual destes no 61eo essencial. Verificou-se que a adubação orgânica provocou um aumento muito significativo na biomassa, no rendimento de 61eo essencial, no teor de fósforo das extremidades floridas e na quantidade de fósforo disponível no solo. A dose de 3,0 kg de adubo orgânico/m2 produziu, em média, os melhores resultados, quais sejam: biomassa - 133,6 g/planta fresca; rendimento de 61eo essencial - 0.151 ml/100g de extremidades floridas frescas; e quantidade de fósforo disponível no solo - 5 ppm. Os índices de refração determinados situam-se entre 1,483 e 1 ,495. Os principais compostos identificados no óleo essencial foram beta-pineno, 1.8-cineol, acetato de bornila, gama-muuroleno, nerolidol e alfa-cadinol, com destaque para o gama-muuroleno, até então não relatado pela bibliografia como componente do 61eo essencial de Achillea millefolium L., e que participou em percentual expressivo - 15 a 28% - no 61eo essencial obtido neste experimento.

O objetivo central é verificar as contribuições do programa na vida das egressas da primeira turma do curso básico de auxiliar de cozinha, formada naquela Instituição. O Programa Mulheres Mil é uma política pública inclusiva que visa proporcionar a mulheres em condições de vulnerabilidade social o acesso à educação, à qualificação, ao emprego e à renda, por meio de uma formação profissional e cidadã. Este estudo parte do histórico das desigualdades enfrentadas pela mulher na sociedade brasileira, principalmente no que se refere ao acesso à educação e ao ingresso no mercado de trabalho. Pesquisas revelam que, apesar de a mulher, atualmente, superar os homens quanto ao nível de escolaridade e representar 40% da força de trabalho global, ela ainda não conseguiu superar o patamar de desigualdade, pois está inserida, em sua maioria, em trabalhos precarizados e de baixa remuneração. Para mudar essa realidade, o movimento de mulheres tem conseguido, por meio das conferências de políticas públicas, dialogar com o Governo e contribuir na elaboração de políticas para as mulheres, que visam diminuir a desigualdade de gênero, contribuir para a elevação da escolaridade, a autonomia das mulheres e o enfrentamento de toda forma de violência. Dentro deste contexto, o Programa Mulheres Mil pretende ser uma política para a igualdade de gênero, que possibilite o acesso à educação e promova a inclusão social de mulheres em situação de risco social, contribuindo para a redução das desigualdades sociais e econômicas das mulheres e combatendo a violência contra a mulher. Considerando tais princípios, esse estudo busca compreender se o programa contribuiu para a melhoria da renda e da qualidade de vida das mulheres que fizeram parte da primeira turma formada pelo Programa no IFG, câmpus de Luziânia. ________________________________________________________________________________ ABSTRACT / This work aimed to study the Thousand Women Program from the experience of the Federal Institute of Goiás (IFG), campus of Luziania. The main objective was to verify the contributions of the program in the life of former students of the first class of the kitchen assistant basic course, formed in that institution. The Thousand Women Program is an inclusive public politics that aims to provide to women, in social vulnerability conditions, access to education, qualifications, employment and income through both professional and civic training. This study is from the historic inequalities faced by women in Brazilian society, especially with regard to access to education and entering in the labor market. Researches show that although woman nowadays surpasses men on the education level and represents 40 % of the global workforce, she still could not overcome the level of inequality, because she is inserted mostly in precarious work and low pay. To change this situation, the women's movement has maneged, through conferences of public politics, to dialogue with the state and contribute to the development of politics for women, who aim to reduce gender inequality, to contribute to increase of schooling, women autonomy and confront of all forms of violence. Within this context, the Thousand Women Program intends to be a politics for gender equality, which provides access to education and promotes social inclusion of women in situations of social risk, contributing to the reduction of social and economic inequalities of women, fighting violence against woman. Considering these principles, this study seeks to understand whether the program contributed to improving the income and quality of life of women who are part of the first graduating class at the IFG program, campus of Luziania

CHALLENGES IN THE DESIGN AND IMPLEMENTATION OF AIRBORNE TELEMETRY PROCESSING SYSTEMS

Otranto, John, Eckman, Bill, Irvin, Dana, Tao, Felix, Lokshin, Kirill, Puri, Amit 10 1900 (has links)
While typical telemetry processing systems are fixed, ground-based assets, certain mission profiles or telemetry acquisition models may involve telemetry processing systems which reside on other platforms, such as ships, mobile vehicles, or airplanes. The design and implementation of telemetry processing systems for these platforms poses unique challenges, which may include requirements for unusual mechanical packaging, heightened electromagnetic sensitivity, or specialized electrical interfaces. This paper presents some of the key challenges involved in the design and implementation of an airborne telemetry processing system and discusses how lessons learned from solving these challenges may be applied to future telemetry processing system designs.
