International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / This paper discusses the use of DSP technology in the embedded real time ingest and pre-processing of weather satellite data. Specifically, case studies are presented in the use of Texas Instrument TMS 320 processors as front-end handlers of GOES MODE AAA and GOES GVAR data formats.

International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / Because of an ever-increasing need for performance and high predictability in modern real-time telemetry systems, the Java programming language is typically not considered a viable option for embedded software development. Nevertheless, the Java platform provides many features that can easily be applied to embedded telemetry systems that other development platforms cannot match. But obviously, there are pitfalls to be aware of. This paper will present an alternative solution to address today’s problems in real-time telemetry systems and will cover the following topics: • Java development platforms for the embedded world • Impact on software portability and reusability • Performance and optimization techniques • Direct access to hardware devices • Memory management and garbage collection • Network-centric component-oriented architecture • Real-time examples from past experience • Future developments

International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / Embedded GIS in Intelligent Navigation System is a special information system. This paper puts forward several basic principles and constraints during design for Embedded GIS at first, and then analyzes the feature of embedded platform and the function of Intelligent Navigation System, and presents a realization scheme of Embedded GIS.

International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / This paper introduces the essential points for designing a navigating system, and describes the modules of a typical vehicle navigator. This paper also gives a practical navigator example. Some experience for design is also mentioned.

In this thesis we derive some basic properties of graphs G embedded in a surface determining a link diagram D(G), having a specified number μ(D(G)) of components. ( The relationship between the graph and the link diagram comes from the tangle which replaces each edge of the graph). Firstly, we prove that μ (D(G)) ≤ f (G) + 2g, where f (G) is the number of faces in the embedding of G and g is the genus of the surface. Then we focus on the extremal case, where μ (D(G)) = f (G) + 2g. We note that μ (D(G)) does not change when undergoing graph Reidemeister moves or embedded ∆ ↔ Y exchanges. It is also useful that μ(D(G)) changes only very slightly when an edge is added to the graph. We finish with some observations on other possible values of μ(D(G)). We comment on two cases: when μ = 1, and the Petersen and Heawood families of graphs. These two families are obtained from K6 and K7 respectively by using ∆ ↔ Y exchanges.

This report describes an embedded system designed to support the development of embedded augmented reality applications. It includes an integrated camera and built-in graphics acceleration hardware. An example augmented reality application serves as a demonstration of how these features are accessed, as well as providing an indication of the performance of the device. The embedded augmented reality development platform consists of the Gumstix Overo computer-on-module paired with the custom-built Overocam camera board. This device offers an ARM Cortex-A8 CPU running at 600 MHZ and 256 MB of RAM, along with the ability to capture VGA video at 30 frames per second. The device runs an operating system based on version 2.6.33 of the Linux kernel. The main feature of the device is the OMAP3530 multimedia applications processor from Texas Instruments. In addition to the ARM CPU, it provides an on-board 2D/3D graphics accelerator and a digital signal processor. It also includes a built-in camera peripheral interface, reducing the complexity of the camera board design. A working example of an augmented reality application is included as a demonstration of the device's capabilities. The application was designed to represent a basic augmented reality task: tracking a single marker and rendering a simple virtual object. It runs at around 8 frames per second when a marker is visible and 13 frames per second otherwise. The result of the project is a self-contained computing platform for vision-based augmented reality. It may either be used as-is or customised with additional hardware peripherals, depending on the requirements of the developer.

Recent development in the field of distributed and decentralized cyber-physical systems led to emerge of DEECo model. As many DEECo use cases are embedded applications it is interesting to evaluate DEECo on embedded hardware. Currently there is only reference DEECo implementation which is written in Java thus cannot be used for embedded applications. As part of this thesis C++ DEECo mapping and embedded CDEECo++ framework were designed using FreeRTOS operating system for task scheduling and synchronization. An example application designed for the STM32F4 board demonstrates usability of the framework. This thesis contains description of the DEECo mapping into the C++ language, source codes of the CDEECo++ framework, documentation and example application including basic measurement of its real- time properties.

A dissertation submitted to the Faculty of Engineering, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Master of Science in Engineering. Johannesburg, 1996. / This report examines the major factors influencing the development of embedded systems. The discussion covers, among other aspects, features of embedded systems that are common to software development in general, the main characteristics of embedded systems, some of the current development strategies, the mlcrocontroller market, language issues and development tools. Following the assessment study and a practical embedded system development, the report concludes that although: I embedded systems are typified by relatively few lines of codes, their complex nature necessitates the application of a disciplined development approach. The report presents a riskbased hardware-software co-design development approach in an attempt to reconcile the existing formal development models to the technical realities of embedded systems. A practical embedded system case study is presented, It involves the development of a microcontroller-based system for the three-phase inverter of an uninterruptible power supply (UPS).
