Patient monitoring systems are becoming increasingly important in accurately diagnosing and treating growing worldwide chronic conditions especially the obesity epidemic. The ubiquitous nature of wearable sensors, such as the readily available embedded accelerometers in smart phones, provides physicians with an opportunity to remotely monitor their patient's daily activity. There have been several...
In order to create low power, low latency and reliable sensing systems, we propose a sensing strategy that identifies local events by the means of global measurements. We claim that capturing events globally, although seems against intuition, can save energy by enabling the organization of effective searching queries. To enable this capability, sensor readings can be combined using electronic switches...
Multi-Vdd techniques enable application of lower supply voltage levels on cells with timing slacks. New voltage assignment, placement and voltage island partitioning methods are needed for better utilization of this technology. Our experiments show that in order to have an effective post placement voltage island generation we need to directly consider the energy consumption overhead of the level shifters...
