Full textAbstract:
Advances in miniature devices for biomedical applications are creating ever-increasing requirements for their continuous, long lasting, and reliable energy supply, particularly for implanted devices. As an alternative to bulky and cost inefficient batteries that require occasional recharging and replacement, energy harvesting and wireless power delivery are receiving increased attention. While the former is generally only suited for low-power diagnostic microdevices, the latter has greater potential to extend the functionality to include more energy demanding therapeutic actuation such as drug release, implant mechanical adjustment or microsurgery. This thesis presents a novel approach to delivering wireless power to remote medical microdevices with the aim of satisfying higher energy budgets required for therapeutic functions. The method is based on ultrasonic power delivery, the novelty being that actuation is powered by ultrasound directly rather than via piezoelectric conversion. The thesis describes a coupled mechanical system remotely excited by ultrasound and providing conversion of acoustic energy into motion of a MEMS mechanism using a receiving membrane coupled to a discrete oscillator. This motion is then converted into useful stepwise actuation through oblique mechanical impact. The problem of acoustic and mechanical impedance mismatch is addressed. Several analytical and numerical models of ultrasonic power delivery into the human body are developed. Major design challenges that have to be solved in order to obtain acceptable performance under specified operating conditions and with minimum wave reflections are discussed. A novel microfabrication process is described, and the resulting proof-of-concept devices are successfully characterized.

This thesis is dedicated to the automation of tests of the thermostats developed by the company Honeywell. The first chapter presents a problem of self-testing of thermostats, followed by a discussion of possible approaches to solutions. Attention is paid to testing the functionality of the HMI of thermostats, especially to the part of the system, that deals with activation of touchscteen, but no other part of the problem are omitted in the text. Discussions of the problematic passes into the design and implementation of specific design solutions. The selected design of 3D-router, which moves in three orthogonal coordinates and resembles to a coordinate drill for example. First, it describes the basic concepts of mechanic and electronic part of equipment, and subsequently is designed and implemented control electronics for mechanical activator HMI. Each of the electronics components are described in detail and values of parts are based on the calculation with the exception of finished parts. The proposal of the electronics follows the possibility of maximization of universality module for applications in similar applications. The functionality of the electronics is controlled by a microprocessor with a custom program that is described in the work. Source code of some the programs is not available because it is know-how of the company. Next part of the thesis deals with optimization of the moving of axes, optimization is done empirically by measuring. An important issue is compliance with the accuracy required position, also part of the work is devoted to the issue of calibration position. Finally is solved the continuity on the superior system. It is designed and implemented the upper layer of the communication protocol used in the company. Work is the solution of specific corporate award thesis. Although it is a very specific role of the works are generally applicable for other applications. In particular, the proposed electronic represents relatively universal controller for stepper motor control.

First, an AT89S51 single-chip microcomputer control circuit is formed to drive
a stepper motor. Secondly, a Galil DMC-2163 motion control card is used.
Finally an ARM Nu-LB-NUC140 teaching board is applied to drive the same
motor. The measured results are showed using a laser range finder.
In this paper, the Borland C++ Builder software is used to develop the stepper
motors HMI. The control program via RS232 transmission to AT89S51 single
chip is used to drive a single-chip stepper motor axis platform in the first control
mode. The other two modes is connected by a fiber optic Ethernet Galil
DMC-2163 motion control card and the use of ARM Nu-LB-NUC140 teaching
board drives the same platform respectively. Although the resolution of the laser
range finder is low, it can still display platform approximate positioning
accuracy. The experiments show that a simple platform positioning can be
achieved by a cheap an AT89S51 single chip or an ARM Nu-LB-NUC140.
Keywords: single-chip, motion control card, stepper motors, ARM Nu-LB-NUC140.

Full textAbstract:
碩士<br>國立勤益科技大學<br>電機工程系<br>106<br>Programmable Logic Controller (PLC) is one of the line interpreting and execution controller. The performance of a PLC-based system is limited by the amount of line commands and the processing times of the CPU embedded. The cycle time of scanning all the command lines once is an important index to evaluate the performance of PLC. A short cycle time means the possibility to increase the system performance by more acts in the system, it also shows that a more powerful system is.
In the research, owing to the time limitation of PLC about the cycle time to complete the scan from the beginning to the end of the program, such that the position control by a general PLC is fail to efficiently reach to the desired performance about the positioning precision. Thus, we used the Field Programmable Gate Array (FPGA) to cooperate with the PLC to complete the compensation about the positioning. The position control is handled by the FPGA-based compensator which accepts the position error from the position sensor and analog to digital converter (ADC), and outputs the pulse commands processed by digital difference analyzer (DDA) to move the stepper motor to conserve the position error in the pre-defined range. Through the experimental results, the positioning precisions can be improved than those only controlled by PLCs.

Full textAbstract:
碩士<br>國立交通大學<br>機械工程系所<br>92<br>The actuation technique of a surface acoustic wave (SAW) stepper with nanometer scale linear motion is experimentally investigated in this thesis. The SAW motor is composed of a stator made of a Y+128o cut, X-propagation lithium niobate substrate and silicon sliders with an array of pillar projections manufactured by semiconductor fabrication technique. Two sets of interdigital transducers deposited on the substrate are used to generate Rayleigh waves with driving frequency up to 9.7 MHz. The SAW motor is driven by friction exerted on the contact area between the slider and surface acoustic waves in retrogressive elliptical locus. Stepping motion of the SAW motor is measured directly by a fiber-optic Michelson interferometer with demodulation in digital signal processing method. A several nanometer displacement in each step is achieved during the experiment.
