This sourcebook offers all the information you need to understand and design biomedical instruments. Biomedical Instruments contains extensive analysis of signal processing electronic design for medical instruments, in-depth descriptions of design methods for medical transducers, and an introduction to medical imaging and tomographic algorithms. Transducers covered include variable R, L, and C, piezoelectric, electrodynamic and magnetostrictive, force balance, and fiber optic. Operational amplifiers, analog filters, biotelemetry, discriminators, phase-locked loops, and microprocessors are...

"If a child wants proof, we can think of 10 different ways to show that we are surrounded by air, but we are, of course, normally unaware that we live at the bottom of an 'ocean" of air. It is claimed, in this book, that we are unaware, similarly, that we are surrounded by an atmosphere of aether. There is one major difference, however: We have not been able to detect the aether. Nevertheless, the aether provides a solution to the following mystery: How can light, or any electromagnetic wave, travel for billions of years across the vastness of the Universe, without losing any energy? The...

This book came about because there are scientific "controversial matters" that gnawed away at my peace of mind. So when I "retired," I finally had time to write about biomedical topics, about some of the weird phenomena of physics, about the minds of suicide bombers, and about less serious subjects such as the condominium swimming pool. My original intention was to have some of this stuff published in a "recognized journal," but one can die (and authors frequently do exactly that) while waiting for publication. Then, my daughter Alice suggested a Web site. What a brilliant and...

"Providing a fascinating alternative to the unwieldy life science sources, this book describes how the nervous system (including the brain) communicates with, sends signals to, and receives input from the sensory organs.

Starting with the basic principles and components of the nervous system with sensory receptors, neurons and dendrites, and the skeletal muscle circuits the authors unfold the mystery of this communication with simple, elegant mathematical formulas to enhance your understanding of how the nervous system functions in complicated auditory and visual systems, and the...
