An apparatus ( ) and method of non-invasive monitoring of gut motility. An ingestible magnet ( M) is swallowed by the patient ( ) and then linear and rotational movement is directionally detected by an external compass ( ). In preferred form, movements of the magnet ( M) are recorded by a memory means ( ) and graphically presented ( ) over a period of predetermined time. An alternate embodiment includes multiple compasses (C C ) for directionally locating the magnet ( M) within the patient ( ).

A temperature gradient system includes an insulated container and heat pumps. Temperature sensing devices measure temperature and a controller controls heat pumps to different temperatures at different positions of the insulated container to produce a temperature gradient. A temperature gradient method includes insulating a sample and controlling temperature to maintain a temperature gradient lengthwise along the sample. The sample is an ice core, in a particular embodiment, and different temperatures are maintained at opposite ends of the insulated container. The sample is a portion of a body, in another embodiment, and the system is configured to accommodate a particular portion of the body for controlled cooling and heating.
