Equipment for data collection and recording has widespread use in a variety of engineering applications. This paper deals with the use of multiprocessor-based architectures in digital data acquisition systems, emphasizing advantages in terms of flexibility and overall system throughput, and the characteristics of the embedded operating system. An overview of the basic architecture of typical data acquisition systems is first presented, followed by a description of a multiprocessing architecture for data acquisition in real-time environments where multiple sampling rates are employed to monitor analog and digital data from different sources. Software and hardware techniques are covered, including the multiplexing of analog signals, digital signal processing, use of masking techniques in the processing of serial data streams, and the use of multi-point buses for communications with peripheral devices. The characteristics of a real-time multi-tasking operating system are analysed. This is the core of the software in any data acquisition system which must meet real-time constraints. In turn, the core of the operating system is the real-time kernel. Emphasis is put into the organization of the kernel, covering issues such as kernel primitives, service calls, interrupt service routines, process scheduling, memory management, and communications and synchronization between processes.

There are two basic approaches to developing data acquisition systems. The first is to buy or develop acquisition hardware and to then write software to input, identify, and distribute the data for processing, display, storage, and output to a network. The second is to design a system that handles some or all of these tasks in hardware instead of software. This paper describes the differences between software-driven and hardware-driven system architectures as applied to real-time data acquisition systems. In explaining the characteristics of a hardware-driven system, a high-performance real-time bus system architecture developed by L-3 will be used as an example. This architecture removes the bottlenecks and unpredictability that can plague software-driven systems when applied to complex real-time data acquisition applications. It does this by handling the input, identification, routing, and distribution of acquired data without software intervention.

The Geosonde radar system, developed for use in bore holes, includes a data acquisition system. Development is currently being conducted by the Radar Remote Sensing Group at the University of Cape Town and Stellenbosch University. This thesis describes the development of a real time operating system and an overall upgrade of basic interfaces to the Geosonde system. The current system employs the use of an embedded MS-DOS operating system and supports basic user control and data exporting over a serial line. The objectives of this thesis are to perform major upgrades on the system by introducing an XML based form of network control and NTP synchronization of the processing board. As a result, an investigation into the adequacy of MS-DOS as a target operating system, bearing in mind the intended upgrades, was carried out. Taking into consideration the failings of MS-DOS as far as the system requirements are concerned, an investigation into available real time executives was conducted and a decision based on the requirements was made. Embedded GNU/Linux was chosen as the target software platform. The software design of the application shows all the necessary design issues considered. The implementation phase of the thesis describes all the tools necessary to implement the embedded Linux system and all the components necessary to meet the needs of the Geosonde system. The network and serial interfaces were tested and shown to be fully functional. The XML based control in particular offers a more flexible and more platform independent solution than the serial interface.

This paper describes the TENA architecture, which has been proposed by the Foundation Initiative 2010 (FI 2010) project as the basis for future US Test Range software systems. The benefits of this new architecture are explained by comparing the future TENA-enabled range infrastructure with the current situation of largely non-interoperable range resources. Legacy equipment and newly acquired off-the-shelf equipment that does not directly support TENA can be integrated into a TENA environment using TENA Gateways. This paper focuses on issues related to the construction of such gateways, including the important issue of real-time requirements when dealing with real-world data acquisition instruments. The benefits of leveraging commercial off-the-shelf (COTS) Data Acquisition Systems that are based on true real-time operating systems are discussed in the context of TENA Gateway construction.

Ubiquitous internet protocol (IP) hardware has reached performance and capability levels that allow its use in data collection and real-time processing applications. Recent development experience with IP-based airborne data acquisition systems has shown that the open, pre-existing IP tools, standards, and capabilities support this form of distribution and sharing of data quite nicely, especially when combined with IP multicast. Unfortunately, the packet based nature of our approach also posed some problems that required special handling to achieve performance requirements. We have developed methods and algorithms for the filtering, selecting, and retiming problems associated with packet-based systems and present our approach in this paper.

The Telemetry Systems Operation (TSO) of CSC in Lompoc, California, has been developing telemetry systems since October 1981. Three major turnkey systems have been developed as well as several smaller derivative systems. Each system, built for a different end-user, was custom fit to support unique requirements and often represented several different techniques for accommodating similar problems within different system architectures. This paper describes the evolution of TM system architectures developed by TSO Lompoc, and the special engineering problems solved in the course of their development to provide the user with accommodating telemetry systems that are responsive, expandable, and cost-effective.

This paper describes a system in which multiple embedded processors are used for real-time processing of telemetry streams from satellites and radars. Embedded EPC-5 modules are plugged into VME slots in a Loral System 550. Telemetry streams are acquired and decommutated by the System 550, and selected parameters are packetized and appended to a mailbox which resides in VME memory. A Windows-based program continuously fetches packets from the mailbox, processes the data, writes to log files, displays processing results on screen, and sends messages via a modem connected to a serial port.

Sistemas supervisores envolvendo software embarcados são encontrados com freqüência e são responsáveis pela supervisão de equipamentos que vão desde máquinas industriais e eletrodomésticos, a celulares e PDAs. Muitos possuem severos requisitos de confiabilidade e tolerância a falhas, bem como características de sistemas de tempo real. Esta pesquisa investiga o uso de tecnologias de ponta como Design by Contract, Agentes de Software, Mock Objects e Componentes de Software no auxílio ao desenvolvimento de sistemas de monitoramento e aquisição em tempo real. Explora-se, ainda, o conceito de sistemas orientados à recuperação. Para realizar tal análise é utilizado como estudo de caso um sistema de inspeção de dutos, que foi implementado utilizando tais tecnologias. De maneira resumida, pode-se dizer que neste estudo de caso percebeu-se que o uso dessas tecnologias fez com que o sistema fosse desenvolvido em um curto espaço de tempo, sendo que questões relevantes não foram prejudicadas, como por exemplo o fato do sistema ser robusto e tolerante a falhas. É importante ressaltar que o sistema apresentado se encontra em uso em inspeções de dutos reais.

This research investigates the use of state-of-the-art technologies such as Design By Contract, Mock Objects, software agents and components in the development of real-time monitoring and data-acquisition systems. Recovery oriented systems concepts are also explored. The case study carried out to the research is a pipeline inspection software system, which uses such technologies. In a nutshell, it can be said that this case study showed strong evidence that the use of these technologies allowed the development in a very short time, without any loss of robustness, fault tolerance and reliability. The developed system is currently being used in real pipeline inspections.

Today’s large-scale signal processing systems impose massive bandwidth requirements on both internal and external communication systems. Most often, these bandwidth requirements are met by scalable input/output architectures built around high-performance, standards-based technology. Several such technologies are available and are in common use as internal and/or external communication mechanisms. This paper provides an overview of some of the more common scalable technologies used for internal and external communications in real-time data acquisition systems. With respect to internal communications mechanisms this paper focuses on three ANSI-standard switched fabric technologies: RACEway (ANSI/VITA 5-1994), SKYchannel (ANSI/VITA 10-1995) and Myrinet (ANSI/VITA 26-1998). The discussion then turns to how Fibre Channel, HiPPI, and ATM are used to provide scalable external communications in real-time systems. Finally, glimpse of how these technologies are evolving to meet tomorrow’s requirements is provided.

Vatavu, Radu-Daniel. "Real-time acquisition of human gestures for interacting with virtual environments." Thesis, Lille 1, 2008. http://www.theses.fr/2008LIL10007/document.
We address in this thesis the problem of gesture recognition with specific focus on providing a flexible model for movement trajectories as well as for estimating the variation in execution that is inherently present when performing gestures. Gestures are captured in a computer vision scenario which approaches somewhat the specifics of interactive surfaces. We propose a flexible model for gesture commands based on a spline representation which is enhanced with elastic properties in a direct analogy with the theory of elasticity from classical physics. The model is further used for achieving gesture recognition in the context of supervised learning. In order to address the problem of variability in execution, we propose a model that measures objectively and quantitatively the local tendencies that users introduce in their executions. We make use of this model in order to address a problem that is considered hard by the community: automatic segmentation of continuous motion trajectories and scale invariant identification of gesture commands. We equally show the usefulness of our model for performing ergonomic analysis on gesture dictionaries

A real-time microprocessor based airborne data acquisition system is described with emphasis on the real-time control software. The system is being currently used by a wide number of airlines in their jetliners for monitoring aircraft performance during flight and recording such data on what is commonly known as the "black box" recorder. The system was primarily developed for use in the new generation of airliners by Boeing Aircraft Company, namely the Boeing 767 and the Boeing 757. At the time of writing this report however, its use has extended to some European aircraft manufacturers, namely Airbus Industries and Fokker. The entire project was a team effort, especially in the design of the hardware. The author's part in this project was the complete design, development and implementation of the real-time control software, including some involvement at a systems level in the hardware design.

A aquisicção de grandes volumes de dados durante uma campanha sísmica exige, necessariamente, mais tempo para o controlo de qualidade (QC). No entanto, o tempo de QC não pode ser extendido devido a limitações do tempo de operação, tendo de ser feito mais rápido, o que pode comprometer a qualidade. A alternativa, alocar mais pessoas e recursos para QC e melhorar a eficiência, leva a aumentos de custo e à necessidade de maiores embarcações. Além disso, o QC tradicional requer tempo de análise após a aquisição, atrasando a desmobilização da embarcação, aumentando assim os custos da aquisição. A solução proposta passou pelo desenvolvimento de um QC automático em tempo real eficiente, testando a Comparação Espetral e o Atributo Razão Sinal-Ruído - ferramentas desenvolvidas no software SPW, usado para processamento de dados sísmicos. Usando este software foi testada a deteção e identificação de dados de fraca qualidade através das ferramentas de QC automáticas e os seus parâmetros ajustados para incluir pelo menos todos os maus registos encontrados manualmente. Foi também feita a deteção e identificação de vários problemas encontrados durante uma campanha de aquisição, tais como fortes ondulações e respetiva direção, o ruído de esteira provocado pelas hélices da embarcação e consequente Trouser’s Effect e mau funcionamento das fontes ou dos recetores. A deteção antecipada destes problemas pode permitir a sua resolução atempada, não comprometendo a aquisição dos dados. Foram feitos vários relatórios para descrever problemas encontrados durante os testes de versões beta do software SPW e os mesmos reportados à equipa da Parallel Geoscience, que atualizou o software de forma a preencher os requisitos necessários ao bom funcionamento do QC em tempo real. Estas atualizações permitiram o correto mapeamento dos headers dos ficheiros, otimização da velocidade de análise das ferramentas automáticas e correção de erros em processamento dos dados em multi-thread, para evitar atrasos entre o QC em tempo real e a aquisição dos dados, adaptação das ferramentas à leitura de um número variável de assinaturas das fontes, otimização dos limites de memória gráfica e correção de valores anómalos de semelhança espetral. Algumas atualizações foram feitas através da simulação da aquisição de dados na empresa, de forma a efetuar alguns ajustes e posteriormente serem feitos testes numa campanha futura. A parametrização destas ferramentas foi alcançada, assegurando-se assim a correta deteção automática dos vários problemas encontrados durante a campanha de aquisição usada para os testes, o que levará à redução do tempo gasto na fase de QC a bordo e ao aumento da sua eficácia.
The acquisition of larger volumes of seismic data during a survey requires, necessarily, more time for quality control (QC). Despite this, QC cannot be extended due operational time constraints and must be done faster, compromising its efficiency and consequently the data quality. The alternative, to allocate more people and resources for QC to improve efficiency, leads to prohibitive higher costs and larger vessel requirements. Therefore, traditional QC methods for large data require extended standby times after data acquisition, before the vessel can be demobilized, increasing the cost of survey. The solution tested here consisted on the development of an efficient Real- Time QC by testing Spectral Comparison and Signal to Noise Ratio Attribute (tools developed for the SPW seismic processing software). The detection and identification of bad data by the automatic QC tools was made and the parameters adapted to include at least all manual QC flags. Also, the detection and identification of common problems during acquisition, such strong wave motion and its direction, strong propeller’s wash, trouser’s effect and malfunction in sources or receivers were carried out. The premature detection of these problems will allow to solve them soon enough to not compromise the data acquisition. Several problem reports from beta tests of SPW were transmitted to the Parallel Geoscience team, to be used as a reference to update the software and fulfil Real-Time QC requirements. These updates brought the correct mapping of data headers in files, optimization of data analysis speed along with multi-thread processing debug, to assure it will be running fast enough to avoid delays between acquisition and Real-Time QC, software design to read a variable number of source signatures, optimization of graphic memory limits and debugging of anomalous spectral semblance values. Some updates resulted from a data acquisition simulation that was set up in the office, to make some adjustments to be later tested on an upcoming survey. The parameterization of these tools was finally achieved, assuring the correct detection of all major issues found during the survey, what will eventually lead to the reduction of time needed for QC stage on board, as also to the improvement of its efficiency.

A flexible, modular method is needed to connect test range data systems to central real-time computer networks. This is achieved by the development of a real-time, networked, VME-based range interface system. Flexibility is achieved by a modular hardware and software design. The modular hardware consists of standard network interfaces, COTS VME interfaces, and a VME single board computer (with an onboard PCI bus). The modular software is implemented in C++ using the VxWorks real-time operating system. This paper describes the conceptual design and development of the Modular Range Interface (ModRI).

Data acquisition for flight test is typically handled by dedicated hardware which performs specific functions and targets specific interfaces and buses. Through the use of an FPGA state machine based design approach, performance and robustness can be guaranteed. Up to now sufficient flexibility has been provided by allowing the user to configure the hardware depending on the particular application. However by allowing custom algorithms to be run on the data acquisition hardware, far greater control and flexibility can be offered to the flight test engineer. As the volume of the acquired data increases, this extra control can be used to vastly reduce the amount of data to be recorded or telemetered. Also real-time analysis of test points can now be done where post processing would previously have been required. This paper examines examples of data acquisition, recording and processing and investigates where data reduction and time savings can be achieved by enabling the flight test engineer to run his own algorithms on the hardware.

Multiprocessing computer systems offer several attractive advantages for telemetry-related data acquisition and processing applications. These include: (1) high-bandwidth, fail-soft operation with convenient, low-cost, growth paths, (2) cost-effective integration and clustering of data acquisition, decommutation, monitoring, archiving, analysis, and display processing, and (3) support for modern telemetry system architectures that allow concurrent network access to test data (for both real-time and post-test analyses) by multiple analysts. This paper asserts that today’s general-purpose hardware and software offer viable platforms for these applications. One such system, currently under development, closely couples VME data buses and other off-the-shelf components, parallel processing computers, and commercial data analysis packages to acquire, process, display, and analyze telemetry and other data from a major weapon system. This approach blurs the formerly clear architectural distinction in telemetry data processing systems between special-purpose, front-end, preprocessing hardware and generalpurpose, back-end, host computers used for further processing and display.

The purpose of this paper is to present a chronology from a Small Business Innovation Research Program (SBIR) showing the impact of a wireless network architecture on future airborne data acquisition systems. The major advantages and challenges associated with the use of wireless network data acquisition versus wired time division multiplexing systems are rooted in data latency, bandwidth efficient data transmission while maintaining a low bit error rate and not interfering with existing avionics. Many of the issues raised are subtle and complex. It is not the intent of this paper to give these issues the thorough academic and technical analysis they deserve. It is the hope of the authors that this paper will generate awareness and discussion on these issues.

The electric power utilities play a vital role in the generation, transmission and distribution of the electrical power to the end users. The power utilities face two major issues, i.e. i) power grids are expected to operate close to the maximum capacity, and ii) there is a need for accurate and better monitoring and control of the power system network using the modern technology and the available tools. These two issues are interconnected as better monitoring allows for better control of the power system. Development of the new standard-based power system technologies contributed to raising the ideas for building of a Smart grid. The challenges are that this process requires development of new control and operation architectures and methods for data acquisition, data transfer, and control computation. These methods require data for the full dynamic state of the power system in real-time, which leads to the introduction of the synchrophasor-based monitoring and control of the power system. The thesis describes the research work and investigations for integration of the existing new power system technologies to build fully automated systems for real-time solution of power system energy management problems, incorporating data measurement and acquisition, data transfer and distribution through a communication network, and data storage and retrieval in one whole system.

Traditional data acquisition systems have relied on physical connections between data sources and data receivers to handle the routing of acquired data streams. However, these systems grow exponentially in complexity as the number of data sources and receivers increases. New techniques are needed to address the ever increasing complexity of data acquisition. Furthermore, more advanced mechanisms are needed that move past the limitations of traditional data models that connect each data source to exactly one data receiver. This paper presents a software framework for the playback of multiplexed data acquired from a network acquisition system. This framework uses multicast technologies to connect data sources with multiple data receivers. The network acquisition system is briefly introduced before the software framework is discussed. Both the challenges and advantages involved with creating such a system are presented. Finally, this framework is applied to an aviation telemetry example.

The Boeing Commercial Airplane Company presently uses an Airborne Data Analysis and Monitor System (ADAMS) to support extensive qualification testing on new and modified commercial aircraft. The ADAMS system consists of subsystems controlled by independent processors which preprocess serial PCM data, perform application-specific processing, provide graphic display of data, and manage mass storage resources. Setup and control information is passed between processors using the Ethernet protocol on a fiber optic network. Tagged data is passed between processors using a data bus with networking characteristics. During qualification tests, data are dynamically selected, analyses performed, and results recorded. Decisions to proceed or repeat tests are made in real time on the aircraft. Instrumentation in present aircraft includes up to 3700 sensors, with projections for 5750 sensors in the next generation. Concurrently, data throughput rates are increasing, and data preprocessing requirements are becoming more complex. Fairchild Weston Systems, Inc., under contract to Boeing, has developed an Acquisition Interface Assembly (AIA) which accepts multiple streams of PCM data, controls recording and playback on analog tape, performs high speed data preprocessing, and distributes the data to the other ADAMS subsystems. The AIA processes one to three streams in any of the standard IRIG PCM formats using programmable bit, frame and subframe synchronizers. Data from ARINC buses with embedded measurement labels, bus ID’s, and time tags may also be processed by the AIA. Preprocessing is accomplished by two high-performance Distributed Processing Units (DPU) operating in either pipeline or parallel environments. The DPU’s perform concatenation functions, number system conversions, engineering unit conversions, and data tagging for distribution to the ADAMS system. Time information, from either a time code generator or tape playback, may be merged with data with a 0.1 msec resolution. Control and status functions are coordinated by an embedded processor, and are accessible to other ADAMS processors via both the Ethernet interface and a local operator’s terminal. Because the AIA assembly is used in aircraft, the entire functional capability has been packaged in a 14-inch high, rack-mountable chassis with EMI shielding. The unit has been designed for high temperature, high altitude, vibrating environments. The AIA will be a key element in aircraft qualification testing at Boeing well into the next generation of airframes, and specification, design, development, and implementation of the AIA has been carried out with the significance of that fact in mind.

The Modular Range Interface (ModRI) is a reliable networked data acquisition system used to acquire and disseminate dissimilar data. ModRI’s purpose is to connect TSPI systems to a central computer network. The modular hardware design consists of an SBC, COTS network interfaces, and other COTS interfaces in a VME form factor. The modular software design uses C++ and OO patterns running under an RTOS. Current capabilities of ModRI include acquisition of Ethernet, PCM data, RS-422/232 serial data, and IRIG-B time. Future strategies might include stand-alone data acquisition, acquisition of digital video, and migration to other architectures and operating systems.

The On-board Data Interface Module (ODIM) was developed specifically to provide real-time casualty assessment telemetry data for the training environment on the instrumented range system at the U. S. Army National Training Center (NTC) located at Ft. Irwin, California. Real-time data acquisition and telemetry systems, such as the ODIM, which enhance the feed back capabilities of fielded training systems are becoming increasingly important to the Department of Defense in these times of shrinking defense budgets and decreasing global stability. The ODIM is designed to combine, process and transmit data from the AH-64 (Apache) 1553 data bus, the Aircraft Survivability Equipment (ASE) threat warnings, the on-board training system laser belt, cockpit kill indicators, and status data. The ODIM also downlinks the stored data though the Micro-B transceiver on the AH-64A. For the application at the NTC, the ODIM looks for very specific data from the AH-64 and the MILES/AGES II system. However, the ODIM is programmable to collect any of the data available from these systems. The uplink/ downlink available through the Micro-B transceiver allows the user access to the ODIM's features even from a remote location.

As modern weapons grow more sophisticated and capable of operating autonomously, the challenge of testing these weapons has also grown more complex. Seekers may be multispectral and must be able to overcome threat countermeasures. To effectively analyze the performance of these weapons, time-correlated test data must be efficiently, simultaneously acquired from both the weapons' internal busses and from the threat countermeasures' internal communication busses, often in a "live fire" environment. The test data must be transmitted to a central processing station where test personnel may immediately analyze the performance of the weapon with the assistance of scientific visualization techniques. In addition, the data must be captured on permanent media for future playback and more detailed analysis. One solution is to link the test article, threat countermeasures and other test support resources through an Integrated Telemetry System (ITS). Instrumentation to acquire high-speed test data is installed in data collection vans that are remotely located in the vicinity of the article under test or in the vicinity of the threat countermeasures systems or test support resources. The remote vans will be interconnected and linked to a control van which provides a centralized test control and monitoring point. Remote Data Formatter (RDF) instrumentation units, located in the remote vans, can acquire data from and control seekers, sensors, emission sources or other equipment located in or near the remote vans. The RDF units can also format the data for transmission to the control van via either fiber optic or microwave radio links. The data transmitted from multiple remote vans is received by Real-time Data Processing System (RTPS) units located in the control van for merging, processing and recording. Some of the processed data can be transferred to a Host Processing System (HPS) where it can be displayed on color graphic workstations. The control van's HPS workstations provide user-friendly displays and menus for test setup and control. Both the remote and control vans are equipped with secure digital communication systems capable of supporting compressed digital video, audio, high-speed instrumentation data and an Ethernet computer network.

The Western Aeronautical Test Range (WATR) of NASA’s Dryden Flight Research Center (DFRC) is facing a challenge in meeting the technology demands of future flight mission projects. Rapid growth in technology for aircraft has resulted in complexity often surpassing the capabilities of the current WATR real-time processing and display systems. These current legacy systems are based on an architecture that is over a decade old. In response, the WATR has initiated the development of the WATR Integrated Next Generation System (WINGS). The purpose of WINGS is to provide the capability to acquire data from a variety of sources and process that data for subsequent analysis and display to Project Users in the WATR Mission Control Centers (MCCs) in real-time, near real-time and subsequent post-mission analysis. WINGS system architecture will bridge the continuing gap between new research flight test requirements and capability by distributing current system architectures to provide incremental and iterative system upgrades.

In the early days of radiotherapy, very little was known about the mechanism of action of ionizing radiation and its side effects. The understanding of molecular genetics has made it clear that radiation damages mainly the DNA of cells. However, since radiation does not distinguish between healthy and tumor cells, the largest improvement of the radiotherapy technology in modern days has concentrated on improving the precision of dose-deliver, with a comparatively lower interest in the fundamental understanding of the basic mechanisms of biological radiation damage.In the first chapter of this thesis, the state of the art conducts to consider the Silicon Nano Tweezers (SNT) as an excellent candidate to explore unknown field of the radiotherapy treatment. The second chapter introduces the SNT and explains its ability to conduct real-time biomechanical characterization of a DNA bundle. The third chapter shows the surrounding SNT setup, and evaluates its capability to measure the biomechanical characteristic of a DNA bundle in liquid under the harsh electromagnetic environment generated by a radiotherapy machine: the Cyberknife. The fourth chapter explains the protocol developed for the DNA characterization in liquid by the SNT. The fifth chapter presents some key results of real-time mechanical characterization of DNA bundles under the Cyberknife irradiation in several conditions, followed by a discussion based on the theoretical model of a randomly damaged DNA bundle. The last part finally concludes on the capability and perspective offered by Micro-electromechanical technologies to push the research in radiotherapy and in medicine
