International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Due to Cost and Safety considerations the Range Division of the 412th Test Wing is upgrading remote telemetry (TM) antenna sites to be operated and monitored remotely. This is possible, in part, due to the installation of fiber optic cable, and the use of ATM communications protocol. Both of these applications significantly reduce signal latency from the remote control station located at Ridley Mission Control Center (RMCC) and the Antenna site. This paper discusses the challenges associated with controlling these sophisticated systems remotely. We will also describe the decisions and how they were made, the concerns over system performance, and the impact to other systems. This paper also addresses the technologies chosen to support the requirements and overcome the challenges. The benefits of remote range sensors are also discussed. We will provide top-level block diagrams of the system architecture.

This paper presents an approach for an automated calibration process for electronic control units (ECU) of power split transmissions in agricultural tractors. Today the calibration process is done manually on a prototype tractor by experts. In order to reduce development costs the calibration process is shifted from prototype testing to software modelling. Simultaneous optimization methods are used within the software modelling to calculate new parameters. The simultaneous optimization includes objective evaluation methods to evaluate the tractor behaviour. With the combination of both methods inside the software modelling, the calibration process can be automated. The success of this approach depends on the quality of the software modelling. Therefore the identification of the initial prototype behaviour and the fitting of the tractor software model is done at the beginning. At the end of the automated calibration the validation and fine-tuning of the calculated parameters are done on the real tractor. These steps are condensed to a five step automated calibration process which includes simultaneous optimization and objective evaluation methods in several applications. After the detailed discussion of this automated calibration process one function of the ECU (one transmission component) will be calibrated through this process as example.

In the field of the industrial automatic control, both MCU (Micro Control Unit) and PLC (Programmable Logic Controller) are widely being used in DCS (Distributed Control System). Since MCU can provide complex process scheduling, accurate timing control and PLC has the advantages of easy programming and maintaining. However, the control programs of the MCU are hard to design and maintain. Identically, the poor signal processing ability, high cost and the restrictive functions are the major defects of PLC. In order to solve the drawbacks described above in MCU and PLC, we provide a PLC-like interface for users to access the devices and set the registers of MCU. Likewise, designers can develop the control program via Event-table-driven modules. On the other hand, our main goal of DCS is to quickly construct the distributed N level network topology based on Modbus protocol, which is efficient and reliable. Therefore, we bring up a data collection method and Slave-to-Slave strategy so as to distribute the master loading, reduce the package transmission times and improve the real-time latency. In conclusion, our research results not only congregate the benefits of MCU and PLC but provide an environment to quickly construct and conveniently monitor DCS, which meets the time-to-market demands.

In the modern day, recognition and tracking of face or the iris is potentially one of the most powerful ways of differentiating between an authentic person and an imposter. Our method uses stereo vision to track the 3-Dimensional coordinates of a target equivalent to a person’s eyes and using a pan-tilt unit we target these areas for additional processing such as iris or facial imaging. One of the most important parts involved in tracking is the way the pan-tilt unit is calibrated. There have been techniques in the past where PTZ (Pan-tilt-zoom) digital camera has been used and calibrated using self calibration techniques involving a checker board calibration grid but the tracking error was found to be large in these techniques. We introduce a more accurate form of calibration of the pantilt unit using photogrammetric calibration technique and view the pan-tilt unit as an emulation of a Pinhole Lens Model to detect and track the target. The system is demonstrated on ideal targets.

The main objective of this project was to create a new, future-proofed, electroniccontrol unit for a test station at GE Healthcare in Uppsala. The control unit was tobe created in cooperation with the technical consultant firm Rejlers. The project consisted of two parts, one investigation part and one design part. The investigation part consisted of examining the previous control unit and its connection between the quality control station and the host computer. This examination resulted in a specification of requirements which was used as a basis in the design of the new control unit. The design part consisted of finding durable and reliable components that met the specification of requirements. During the design process the work was documented and compiled in a technical documentation for the control unit. The project resulted in a new control unit that was improved by using a programmable logic controller that was directly compatible with LabVIEW, moving external power supplies inside the control unit to limit the number of cables and adding cartridge fuses for safety. It also resulted in a full technical documentationof the unit, facilitating future maintenance. The new control unit was considered to be future-proofed, but in order to consider the entire test station future-proofed the quality control station would have needed to be replaced as well. At the time this report was written, the new electronic control unit had been designed and was under construction.

The topic of this thesis is the design and implementation of an interface for communication with modern electronic control units of EDC group. The work is devoted to an introduction to the world of automotive diagnostics, analysis of communication protocols and rules for transmitting messages. The greater part is devoted to the analysis of the CAN bus belonging protocols. The outcome of this work is the design and implementation of a communication device for diagnostics of electronic control units of EDC group.

The main purpose of this project is to analyse used protocols in vehicles available under the OBD II specifications. In the project we will also focus on processing diagnostic data. We will design device for vehicle diagnostic. This device will be able to send processed data on external web server via Internet network. Obtained data will be saved on data server. Building of functional receiver will be the major part of master´s thesis.

This graduation theses is focus on hardware and software description for control module, which is part of air-condition unit made be company THERMO KING. All circuit connected thought buses like IIC,CAN and display are explain in detail.

The main goal of this project is to understand broadband sold Robonova-I humanoid robot and to design new improvements. The thesis is divided into five main chapters: The first of them (Robonova-I) is concerning the kit of Robonova-I, its completion and control possibilities. In details it deals with used servo motors, their operating and compares them. The next chapter is concerning the design of the control unit along with description of architecture of the processor and control possibilities with demonstrational board. In third there is a software solution of particular methods and commands which control the unit with demonstrational board. Chapter “The Design of Printed Circuit Board” describes facilities of the designed printed circuit board. The last chapter describes the final program for robot control through the use of computer and some of the algorithms by means of which the robot controls the microprocessor.
