2 Session Titles and Track & Course Track 1 - Medical Design The diagnostic and treatment of abrupt and chronic conditions require medical systems capable of performing high accuracy measurements in a variety of environments. From electrochemical analysis found in blood glucose systems to measuring biopotentials Analog Signal for generated by the de-polarization and re-polarization of living cells, today s medical Medical Applications such as ECG applications demand more and more integration, systems with superior performance and and Pulse Oximetry reliability, as well as lower power consumption. This presentation will take you through a quick overview of the key considerations to have in mind when designing analog front ends in various high-precision medical applications such as pulse oximetry and ECG. Telehealth: Trends, Challenges, Wireless Standards and Solutions Telehealth, via portable patient monitoring, is gaining tremendous momentum in recent years and is enabling independent elderly living, reducing health care costs, and improving access to health care services. This session will present an overview of telehealth systems and also provide a quick overview of a telehealth link as well as the key blocks (Personal Health, Aggregation Manager, Health Record Center). What will then be discussed is how to make the choice of a wireless standard when setting up a PAN (Personal Area Network) and a WAN (Wide Area Network), what makes these standards applicable and what key metrics to key in on when choosing a particular wireless standard. A discussion will also take place on possible system design choices: processor, power management and user interface. TI Solutions for Personal Health, Fitness and Medical Imaging BioSmart: Nimble Medical Apps that Use Integrated MSP430 Come get an insider s peek into TI s latest roadmaps for Personal Health, Fitness, and Medical Imaging solutions including Body Composition, Pulse Ox, ECG, Ultrasound, MRI, and more! Portability--meaning small, easy to use and long battery life--continues to be a strong trend in medical products. The MSP430 microcontrollers implement the latest in package technology to support manufacturing of small medical equipment with space restrictions. MSP430 also helps to reduce design complexity and time to market. In most portable medical equipments, the actual physiological signals are analog and require signal conditioning techniques, such as amplification and filtering, before they can be measured, monitored, or displayed. The MSP430 microcontroller offers integration of the complete signal chain required for these applications such as personal blood pressure monitors, blood glucose meters, pulse oximeters, and heart rate monitors. Utilizing DC/DC Converters with High-Speed Data Converters Customers continually demand lower power consumption from our high-speed ADCs. The power efficiency in their system is usually not so good because the standard, proven method is power an ADC with an LDO. In the past this was necessary to ensure best performance. However this configuration comes at the cost of a lot of wasted power. Advances in ADC design and process technology along with improved DC/DC converter design allow designers to eliminate the LDO and power the HS ADC directly from a switching regulator without having to sacrifice performance. This lecture will compare traditional LDO power supplies against new DC/DC versions for our ADS548x, ADS61xx and ADS41xx converters.
