Data acquisition quality and data fusion for personal portable wireless vital signs scanner

A method comprising:

• forming a circuit comprising a first electrode for making contact at a first point on a user, and a second electrode for making contact at a second point on the user, the first electrode configured for coupling to the second electrode through the first point and the second point;
• selecting a sensor from a set of vital signs sensors;
• determining a first resistivity comprising an electrical resistance at one or more of the first electrode and the second electrode;
• comparing the first resistivity to a predetermined threshold;
• concurrently sensing data from the user with the set of vital signs sensors over a period of time;
• over the period of time, determining a plurality of different vital sign values for a respective plurality of different vital signs associated with the user in response to the sensed data from sensors selected from the set of vital sign sensors;
• based on the comparison of the first resistivity to the predetermined threshold, designating at least two of the determined vital sign values as valid;
• and
• fusing together at least two different vital sign values designated as valid to form a value of another vital sign associated with the user.
