1. A data gathering method carried out with respect to a first device and a second device, each of the first device and the second device comprising a respective electrical signal detector having respective first and second electrodes, the method comprising the steps of:
- placing a first device upon a first limb of a living body, the first device encircling said first limb, the first electrode of the first device juxtaposed with said first limb, the second electrode of the first device more distant from the first limb than the first electrode;
placing a second device upon a second limb of a body, the second device encircling said second limb, the second limb being a limb other than the first limb, the first electrode of the first device juxtaposed with said second limb, the second electrode of the second device more distant from the second limb than the first electrode;
at the first device, measuring electrical signals at the respective signal detector differentially between the respective first and second electrodes, yielding a first data stream indicative thereof;
at the second device, measuring electrical signals at the respective signal detector differentially between the respective first and second electrodes, yielding a second data stream indicative thereof; and
analyzing the first data stream and the second data stream together, thereby deriving information of interest about the body.

Abstract
Sensing is carried out from locations at considerable remove from the stomach. Cooperating sensor electronics are placed at each of two wrists of the patient. The potential discomfort and inconvenience of an abdominal patch are reduced or eliminated. And alternative power sources become available.
