Book Description
"With the advent of manned space flight, the National Aeronautics and Space Administration (NASA) has conducted intensive investigations on the physiological makeup of the human body. The last decade has seen major advances in the use of radiotelemetry in physiological research. Revolutionary developments in microelectronics are making possible smaller telemetry systems that can be wholly implanted in laboratory animals. The NASA Ames Research Center has been in the fore-front of such research and has developed many implantable biotelemetry devices now considered by many as a standard method for monitoring physiological functions in animals. This report describes biotelemetry developments at Ames, tracing the evolution of concepts underlying the accurate and reliable biotelemetry systems of today. Such systems are described in sufficient detail for the reader to select designs to meet specific needs. Through its Technology Utilization Program, NASA strives to make the results of such work widely available for the use of those outside the aerospace community. This publication is one of a series intended to achieve those objectives."--Foreword.

Book Description
The development of safe implants is one of the key priorities of biomedical engineering. Healthcare professionals are trying to create new and sophisticated strategies to improve and support people with disabilities using implants. The research described in this thesis focuses on developing a power supply from a wireless source for implants that will also serve as a wireless data telemetry channel for communication purposes. The design analysis of inductive coupled biomedical implant is expanded. The proposed method of powering the implant is a Class-E amplifier. An analytic approach is given in relation to tuning the class-E amplifier to maximize power transfer. This thesis culminates in specific recommendations for system level design including coil design, miniaturisation, coupling distance, stability of power supplies, consistent energy transfer and the ensuing electromagnetic exposure.The telemetry system for data transfer between implants and outside world has been also studied. This bio-telemetry system setup should ensure an optimal data rate, proper energy levels, low error rates, and a reliable power source. The efficiency of the system is crucial for these implants, and the use of efficient and low power consumption amplifiers and modulation schemes has been discussed in detail. The advantages of Pulse Width Modulated - Amplitude Shift Keying (PWM-ASK for short) are presented in comparison to current modulation schemes used in nowadays implants. Beside inductive coupled implants, this thesis also introduces a study of designing a wireless powered biomedical implant using capacitive coupling. A comparison between inductive and capacitive coupling is presented, while considering biotelemetry and power efficiency. A capacitive coupled biomedical implant is demonstrated through mathematical terms and simulations.

Book Description
Handbook of Biomedical Engineering covers the most important used systems and materials in biomedical engineering. This book is organized into six parts: Biomedical Instrumentation and Devices, Medical Imaging, Computers in Medicine, Biomaterials and Biomechanics, Clinical Engineering, and Engineering in Physiological Systems Analysis. These parts encompassing 27 chapters cover the basic principles, design data and criteria, and applications and their medical and/or biological relationships. Part I deals with the principles, mode of operation, and uses of various biomedical instruments and devices, including transducers, electrocardiograph, implantable electrical devices, biotelemetry, patient monitoring systems, hearing aids, and implantable insulin delivery systems. Parts II and III describe the basic principle of medical imaging devices and the application of computers in medicine, particularly in the fields of data management, critical care, clinical laboratory, radiology, artificial intelligence, and research. Part IV focuses on the application of biomaterials and biomechanics in orthopedic and accident investigation, while Part V considers the major functions of clinical engineering. Part VI provides the principles and application of mathematical models in physiological systems analysis. This book is valuable as a general reference for courses in a biomedical engineering curriculum.

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 26 (thesis year 1981) a total of 11 ,048 theses titles from 24 Canadian and 21 8 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 26 reports theses submitted in 1981, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
