Wireless implantable load monitoring system for scoliosis surgery

Zbinden, Daniel 06 1900 (has links)
Surgical correction of scoliosis is a complicated mechanical process. Understanding the loads applied to the spine and providing immediate feedback to surgeons during scoliosis surgery will prevent overloading, improve surgical outcome and patient safety. Long-term development of residual forces in the spinal instrument after surgery with the continual curvature changes over time has been unknown. The goal of this research work was to develop a wireless implantable sensor platform to investigate the loads during and after surgery. This thesis describes research leading to the design of a sensor platform that uses both 403 MHz and 2.45 GHz for wireless communication, and reports the resolution and accuracy of the built-in temperature sensor, the A/D accuracy of the sensing platform, the power consumption at different operation modes, the range of the wireless communication and the discharge characteristics of a potential capacitive power module. / Biomedical Engineering

Bounds and algorithms for carrier frequency and phase estimation /

Rice, Feng. Unknown Date (has links)
Quadrature amplitude modulation (QAM) is a highly bandwidth efficient transmission technique for digital communications. It makes use of multiple signal phase and amplitude levels to carry multiple bits per symbol. This requires accurate and robust carrier phase and frequency estimation in the receiver. / Thesis (PhDElectronicEngineering)--University of South Australia, 2002.

Yu, Sam Shaokai January 1999 (has links)
Bibliography: leaves 203-219. / 226 leaves : ill. ; 30 cm. / Title page, contents and abstract only. The complete thesis in print form is available from the University Library. / Develops efficient analytical methodologies for multimedia traffic integration and improved design tools to enhance data performance. The call admission control policies proposed are not only able to enhance traffic performance but also maintain communication quality at an acceptable level. In particular, the multiple priority scheme is a promising technique for the control of packet congestion in a high-speed wireless multimedia environment. / Thesis (Ph.D.)--University of Adelaide, Dept. of Electrical and Electronic Engineering, 2000?
