Abstract: A system and method are described herein for a sensor device which biomechanically detects in real-time a user's movement state and posture and then provides real-time feedback to the user based on the user's real-time posture. The feedback is provided through immediate sensory feedback through the sensor device (e.g., a sound or vibration) as well as through an avatar within an associated application with which the sensor device communicates. The sensor device detects the user's movement state and posture by capturing data from a tri-axial accelerometer in the sensor device. Streamed data from the accelerometer is normalized to correct for sensor errors as well as variations in sensor placement and orientation. Normalization is based on accelerometer data collected while the user is wearing the device and performing specific actions.

Abstract: Disclosed are a method and a system using user personal, CBC, CMP and Lipid Panel data to detect a user acute myocardial infarction (AMI) risk and help user monitor AMI risk. Most AMI risk screening and diagnosis are related with the markers, video, image data, etc. although past researches have shown that serum albumin, RBC, MCV, MPV and PDW are all significantly correlated with AMI risk, use of the blood test results of CBC, CMP and Lipid Panel data to detect and monitor AMI risk has never been reported. Traditionally, AMI risk detecting and monitoring have been managed by doctors and hospitals and a user is unable to do it by himself or herself. The purpose of this invention is to provide an intelligent AMI risk detecting and monitoring system enabling users to detect and monitor AMI risk.
