5 6 Abstract 7 A unique method has been developed to scavenge energy from monocrystaline solar cells to power wireless router nodes used in 8 indoor applications. The system's energy harvesting module consists of solar cells connected in series-parallel combination to scavenge 9 energy from 34W fluorescent lights. A set of ultracapacitors were used as the(More)
Obesity is a global epidemic that imposes a financial burden and increased risk for a myriad of chronic diseases. Presented here is an overview of a prototype automated ingestion detection (AID) process implemented in a health monitoring system (HMS). The automated detection of ingestion supports personal record keeping which is essential during obesity(More)
Sleep Apnea is a well-documented and chronic problem that can result in various life threatening disorders. Detecting and diagnosing sleep apnea requires a long duration sleep study that makes use of various sensor based monitors. The need for long duration sleep studies at a special care provider facility and lack of simple portable monitors result in many(More)
Sleep Apnea is a chronic and widespread problem that is characterized by periods of pauses in breathing during sleep. It can lead to several life threatening conditions if left undiagnosed.
