Abstract:

Apparatus and method are provided for synchronized multiple vital health measurements. In one novel aspect, an integrated wearable device with multiple sensors that can collect multiple vital health signals, digitize them, send them through wireless network to a receiver. In one embodiment, the wearable device has a plurality of different types of sensors including at least one or more acoustic-to-electric sensors collecting phonocardiogram (PCG) electrical signal and one or more electrocardiogram (ECG) sensors, a control module includes a synchronization circuitry that synchronizes measurements of the plurality of different types of sensors. In another novel aspect, a system performs a synchronized measurement using a plurality type of health-monitoring sensors, performs a correlation analysis of the plurality of measurement results using selected one or more analytical rules, and obtains a set of parameters with recognized medical values and generating one or more medical health records based on the correlation analysis.

Abstract:

An approach is provided for correcting a reference clock of a GPS receiver. The approach involves determining one or more frequency offset values. The approach also involves determining one or more codes associated with one or more satellites. The approach further involves determining a second code associated with the one or more satellites. The approach additionally involves determining one or more delay values between the second code and the one or more first codes. The approach also involves determining one or more proportional values based on the one or more delay values and a determined correlation. The approach further involves determining one or more correlation peak values and determining one or more estimated frequency offset error values based on the one or more correlation peak values. The approach additionally involves causing a calibrated reference clock frequency value to change to a recalibrated reference clock frequency value based on the estimated frequency offset error values.
