Abstract: A novel and improved method to detect indirectly a temperature of an object employing nuclear magnetic resonance techniques (NMR). The method involves obtaining an NMR spectrum to determine chemical shift, relaxation times, spin-spin couplings or quadrupole couplings for an element of a compound having at least one conformational isomer wherein the compound is influenced by a temperature of the object. Uniquely, the present invention may detect temperature in the body of an animal. Further, the present invention discloses a novel method to determine and monitor thermal physiological states in an animal as well as determine and monitor thermal states in an object. Because of the unique and advantageous non-invasive, non-destructive and non-ionizing properties, the present invention may be employed in an object or animal continuously.

Abstract: A water fillable pad for positioning on the tub bottom, the top wall of said water fillable pad having a plurality of elongated air tubes serially apertured, and a compressor with a heating element delivering heated compressed air through a manifold tube to said air tube so heated bubbles rise and agitate the tub water around the bather. The water fillable pad has a hingedly connected air inflatable back rest and an air inflatable side pad which drapes over the tube side wall and down to the float surface. A foot drain tray assembly is mounted to the free side edge of the air inflatable side pad member on which a bather can stand after finishing his bath. The foot drain tray assembly can be tucked under the water fillable pad when arching the air inflatable side pad member, thus forming a dome for the bather and a capture space for the discharged air bubbles.
