METHOD OF LOCATING AN INGESTED CAPSULE
First Claim
1. A method of determining movement of an ingested capsule from a first segment of a gastrointestinal tract to a second segment of said gastrointestinal tract comprising the steps of:
- providing an ingestible capsule having a pH sensor and a pressure sensor;
having a subject ingest said capsule;
recording pH measurements from said pH sensor as a function of time as said capsule moves through at least a portion of said gastrointestinal tract of said subject;
recording pressure measurements from said pressure sensor as a function of time as said capsule moves through at least a portion of said gastrointestinal tract of said subject;
deriving a frequency of contraction pressure pattern as a function of time and said pressure measurements; and
identifying an appreciable variation in said frequency pressure pattern in substantially the same time period as an appreciable variation in said pH to determine said capsule'"'"'s location at a first position between the ileum and the caecum of said gastrointestinal tract of said subject.

Abstract
A method of determining the location of an ingested capsule comprising the steps of providing an ingestible capsule having a pH sensor and a pressure sensor, having a subject ingest the capsule, recording pH measurements from the pH sensor as a function of time as the capsule moves through at least a portion of the gastrointestinal tract of the subject, recording pressure measurements from the pressure sensor as a function of time as the capsule moves through at least a portion of the gastrointestinal tract of the subject, deriving a frequency of contractions pressure pattern as a function of time and the pressure measurements, and identifying an appreciable variation in the frequency pressure pattern in substantially the same time period as an appreciable variation in the pH to determine the capsule'"'"'s location at a first position in the gastrointestinal tract of the subject.

15. A method of determining movement of an ingested capsule from a first segment of a gastrointestinal tract to a second segment of said gastrointestinal tract comprising the steps of:
-
providing an ingestible capsule having a pH sensor and a pressure sensor; having a subject ingest said capsule; recording pH measurements from said pH sensor as a function of time as said capsule moves through at least a portion of said gastrointestinal tract of said subject; recording pressure measurements from said pressure sensor as a function of time as said capsule moves through at least a portion of said gastrointestinal tract of said subject; deriving a frequency of contractions pressure pattern as a function of time and said pressure measurements; providing a reference pH and a reference frequency pressure pattern; analyzing said pH variations for said subject and said frequency pressure pattern variations for said subject relative to said respective references to determine said capsule'"'"'s location at a first position. - View Dependent Claims (16, 17, 18, 19)
