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 / The F-22 flight test program used a traditional distributed data acquisition system and a non IRIG-106 Chapter 10 recording system for its flight test program. In addition, it required a separate and very large Harris DAU system to monitor and record avionic data buses carrying secure data. Due to the size, cost, and the obsolescence of the Harris DAU system and components, Lockheed evaluated replacement systems. TTC proposed to develop F-22 specific Fiber Optic avionics bus monitors and an avionics PCM Data Selector / Encoder as part of its distributed IRIG-106 Chapter 10 Multiplexer / Recorder system to replace the Harris DAU. This replacement system challenges the traditional system approach used in many flight test programs. This paper describes the evolutionary process to design two independent distributed data acquisition and recording systems handling data with different classification levels. The data separation is maintained by way of system wiring, proper hardware that holds no residual data once power is removed, different transmission channels, hardware-based message blocking, and a separate IRIG-106 Chapter 10 multiplexing / recording system.

International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / The role of recorders in telemetry applications has undergone many changes throughout the years. We’ve seen the evolution from multi-track tape to disk to solid state technologies, both for airborne and ground based equipment. Data acquisition and collection system design has changed as well and a recent trend in airborne is to merge acquisition and recording. On the ground, increased decentralization of data collection and processing has generated the requirement to provide backup storage to protect against communication circuit outages. This paper explores the trend to adopt network based data acquisition, collection, and distribution systems for telemetry applications and the impact on recording techniques and equipment. It shows that in this emerging approach the recorder returns to its root mission of attempting to provide the fastest, largest capacity for the least amount of investment. In a network based architecture the recorder need only accept and reproduce data operating independently from the acquisition process.

ITC/USA 2011 Conference Proceedings / The Forty-Seventh Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2011 / Bally's Las Vegas, Las Vegas, Nevada / The F-22 Quick Response Package was designed to efficiently solve aircraft anomalies in the field. Providing this capability would enhance aircraft combat availability and lower maintenance costs. Using the current F-22 instrumentation flight test system design package as a baseline, a smaller, and much more versatile, version of the system was designed. This new design concept includes a data acquisition and recording system on a single pallet called the Quick Response Package (QRP). The QRP can be installed in any operational F-22 war fighter in a single production shift with no intrusion to the aircraft's systems readiness. The data acquisition and recording capabilities provide a near real-time field solution without excessive downtime or pilot intervention. This paper describes the design requirements, the design concept and packaging details of the QRP.

ITC/USA 2011 Conference Proceedings / The Forty-Seventh Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2011 / Bally's Las Vegas, Las Vegas, Nevada / Today's telemetry systems need to be highly configurable and easily extensible to support a constantly growing number of data acquisition/transmitting components from different manufacturers. One way to achieve this goal is through a standardized descriptive language that can define the system structure as well as end-node devices. The integrated Network Enhanced Telemetry (iNET) program has explored such a possibility by creating a series of standards to define how devices are configured and interoperate with each other. As one of the standards created by the iNET program, the Metadata Description Language (MDL) specifies a common interchange language that defines and configures a Telemetry Network System (TmNS). MDL Instance Documents are used to exchange test requirements, data formats and configuration information among the devices within a TmNS system. MDL, together with other standards created in the iNET program, serve as a foundation for assembling a modern telemetry system. This paper starts with an overview of the MDL-based system description architecture. A typical configuration workflow of an MDL-based system is then described. iNET functionality implementations for new and legacy devices are used as examples to illustrate the power of MDL-based design, as well as the challenges and issues associated with the implementation of the MDL standard. We explain and evaluate the design decisions for a new product, the L-3 NetDAS Recorder, as the case study. We also discuss how a legacy Data Acquisition Unit (DAU) acting as an LTC Data Source Unit can be updated to support MDL based iNET functionality. Our practice shows that more efficient data acquisition systems can be designed and implemented using the metadata definition language as a core tool for equipment and system description. We conclude the paper with design tradeoffs and discussions.

International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Low cost recording devices for telemetry and other data acquisition applications are of vital importance in light of today's shrinking budgets and project cut-backs. The desire to replace large, expensive, multi-channel recorders with smaller, less expensive recorders is becoming commonplace in government and industry. Many of these small recorders in the past have been limited to a single recording channel, and to one particular data type, due to recorder architectures. The 8 millimeter (8mm) tape cartridge recorder has been looked at in the past as a low cost recording device, however products utilizing this technology have been strictly limited in the number of channels, and data types. In response to this need, Veda has developed a new data acquisition recorder utilizing an 8mm recorder packaged in a small, flight qualified rugged enclosure with modular, and interchangeable, input channels. These microprocessor controlled inputs are capable of accepting PCM telemetry, MIL-STD-1553, voice, IRIG time, and ARINC 429/629 data. The new architecture allows for multiplexing of multiple channels onto the single channel tape medium as well as direct playback from the recorder for certain data types. This paper will discuss the recorder's architecture, design problems solved during development, and general capabilities.

The goal of this work is to design and fabricate an autonomous acoustic recording system which is low cost, reconfigurable and portable for acoustic research. The system consists of four components, including a compact single-board computer (Celeron 1G), a 12-bit A/D converter (PCM-3718HO), a 20/40 dB gain amplifier and an useful power management circuit board. C and LabVIEW programs with multiple threads are developed to control the I/O's, digitize the underwater acoustic signals and stream data to the hard disk continuously. Currently, the throughput of data stream attains to 83 kHz. It were tested by six significant experiments to show its feasibility. At first, taking the function generator as signal source to verify no distortion caused by the system. Two ITC-6050C hydrophones are connected to the system as the receivers. The system was tested with experimental propeller producing broadband noise to calibrate the hydrophones in the experimental sink. To verify their performance, the receivers also work with the calibrated one B & K 8104 for reference. In order to understand the influence of self-noise, the system is planned to record known signal producing by hydrophone CTG-0708. By repeating similar calibration experiment, the system operates with an autonomous recording system Bioacoustic probe to understand what deficiency we should improve afterward. Further, a field test was conducted in the designated natural laboratory of shallow bay area. Post-processing of the data resulted in range-frequency plot shows that the interference pattern reported in the literature was captured. According to above-mentioned tesing, the system can be applied to underwater acoustics. This system, connected with multiple hydrophones, will be applied in the research for target detection, the harbor protection and so on.

Objetivou também elaborar repertório didático de flauta doce com partituras cifradas para orientação dos professores bem como outro direcionado para as crianças acompanharem as canções. A partir dos laboratórios e vivências nas aulas de música, sentiu-se a necessidade de criar um repertório próprio para esse fim. O repertório foi composto pela pesquisadora, contendo 68 canções favorecendo o aprendizado de uma forma variada e progressiva. A pesquisadora testou a eficiência dessa metodologia com as crianças das 28s. séries numa escola particular de Campinas onde atua há sete anos. Primeiramente pela palavra cantada, pelo ritmo e com a exploração dos ostinatos no próprio corpo. Nessa pesquisa apresenta também como foi o funcionamento dessas aulas, ou seja, como elas aconteceram. Procura mostrar o quanto as crianças se motivaram e a felicidade em tocar uma pequena melodia, mesmo quando envolvendo apenas uma nota musical. A flauta doce foi escolhida pela pesquisadora porque é um instrumento que tem uma vocaçãp natural para a musicalização. Seu som é suave e de fácil emissão, e a digitação segue uma lógica simples e natural proporcionando resultados rápidos e progressivos num curto período, além de ser um instrumento de 'baixo custo e acessível a grande parte da população. O objetivo do projeto é capacitar crianças a utilizar o instrumento e estimular o gosto pela música, desmistificando os tabus de que apenas os bem dotados conseguem tocar um instrumento. Adota também a concepção da cultura integral, colaborando na formação da criança, desenvolvendo a concentração, disciplina, desembaraço, autoconfiança, criatividade, sensibilidade, memória e raciocínio. Foi baseado nos educadores Carl Orff e Shinichi Suzuki ambos favoráveis ao ensino de música em conjunto / Abstract: The following project had as its major objective, working with the recorder as an element of musicalization in the first years of Elementary School. Nevertheless, it involved elaborating a repertoire for the recorder with music scores to guide teachers and also for the children to follow the music. By means of experiments during music classes, a necessity of creating a specific repertoire to attend them was identified. The repertoire was composed by the researcher, containing 68 songs encouraging learning in a varied and progressive way. The researcher tested the efficiency of this methodology with 2nd grade children in a private school in Campinas (SP), where she has worked for seven years. This was accomplished primarily through singing, clapping, rhythm and by exploring ostinatos on our body. This research also presents the functioning of the music classes and how they were conducted in arder to show how much the children were motivated and their happiness in playing a simple melody, even when it involved only one musical note. The recorder was chosen by the researcher because it is an instrument that presents a natural vocation towards musicalization. Its sound is smooth and of easy production, following logical patterns and naturally fast and progressive results in a short periof of time; besides this it is a low cost instrument and it is accessible to great part of the population. The objective was to capacitate children to use the instrument and to encourage enjoying music, demystifying the misconception that only talented people are able to play. The conception of integral culture is adopted, collaborating to the child's development, developing concentration, discipline, disembarrassment, self-confidence, creativity, sensibility, memory and reasoning. This methodology was based upon the ideas and theories of Carl Orff and Shinichi Suzuki, both in favor of musical teaching in groups / Mestrado / Mestre em Música

The small recorders, the flageolet, the fife, and the piccolo are octave flutes, sounding at four-foot pitch. The bulk of the literature relating to the recorder in the late seventeenth- and eighteenth-century England focuses on the alto (treble), for this was the most commonly used member of the family, but octave recorders have never been the subject of detailed scrutiny. There is no comprehensive study of the flageolet or of the fife in England during this period, and virtually nothing has been written on the early use of the piccolo. The thesis examines the organology of the four instruments, with most attention being given to the recorder, the dominant octave flute of the era; the changes in the instrument from the sixteenth to the eighteenth century are described, and related to changes in assigned music. The reasons for the displacement of the flageolet by the recorder in the late seventeenth century and the recorder's substantial displacement by the German flute in the eighteenth are explored. Duct flutes have long been the particular province of amateur musicians, who often studied from a self-instructor, and examples of these tutors are examined, together with a representative repertoire. Particular note is made of the English 'small flute concerti' and the use of the sopranino recorder in the late eighteenth century. A chapter examines social, financial, and performance aspects (including performance venues); professional and amateur usage of the instruments and gender differences are discussed. A comparison is made of the usage of the instruments in Continental Europe and England, where differing practices are observed regarding tutors, repertoire, and, in particular, the usage of the piccolo. The introductory review of extant literature indicates thirteen matters in which I consider the literature on octave flutes 1660 - 1800 to be deficient. The thesis explores these lacunae.
