Abstract
Abstract An implement for measuring an individual's skin temperature which is convenient and easy to use. Two liquid crystal indicators are attached to a base which is convenient to the user. When the user touches the implement, the liquid crystals would indicate how close the individual is to an individually tailored goal temperature which is a function of the state of relaxation of the individual. Depending upon how close the individual is to his goal temperature, a number of learned relaxation "cues" is utilized to help the individual obtain his goal temperature.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
169 words
A device for indicating the state of relaxation or tension of an individual with respect to a particular optimum predetermined temperature of the individual as measured by the individual's fingertip skin temperature comprising: a thermally conductive planar surface; two temperature sensitive liquid crystal indicators located on said planar surface, one indicator only becoming visible when the individual's fingertip skin temperature is less than the predetermined temperature, and the second indicator only becoming visible when the individual's skin temperature is greater than the predetermined temperature; and a plurality of temperature sensitive liquid crystal relaxation cues located on said planar surface, said relaxation cues becoming visible only when the skin temperature of the individual is less than that of the predetermined temperature of the individual, wherein said temperature sensitive liquid crystal indicators indicate the proximity of the individual's fingertip skin temperature to that of the predetermined temperature and said temperature sensitive relaxation cues assist the individual in attaining the predetermined temperature by allowing the individual to recall certain learned relaxation techniques.
Claim 2
Independent Claim
169 words
A device for indicating the state of relaxation or tension of an individual with respect to a particular optimum predetermined temperature of the individual as measured by the individual's fingertip skin temperature comprising: a thermally conductive planar surface; two temperature sensitive liquid crystal indicators located on said planar surface, one indicator only becoming visible when the individual's fingertip skin temperature is less than the predetermined temperature, and the second indicator only becoming visible when the individual's skin temperature is greater than the predetermined temperature; and a plurality of temperature sensitive liquid crystal relaxation cues located on said planar surface, said relaxation cues becoming visible only when the skin temperature of the individual is less than that of the predetermined temperature of the individual, wherein said temperature sensitive liquid crystal indicators indicate the proximity of the individual's fingertip skin temperature to that of the predetermined temperature and said temperature sensitive relaxation cues assist the individual in attaining the predetermined temperature by allowing the individual to recall certain learned relaxation techniques.
Claim 3
Dependent Claim
70 words
A device for indicating the state of relaxation or tension of an individual in accordance with claim 1, wherein the temperature range of each of said temperature sensitive relaxation cues overlaps but is different than the temperature range of the remaining temperature sensitive relaxation cues, such that as the skin temperature of the individual approaches the predetermined temperature, the number of temperature sensitive relaxation cues visible to the individual decreases.
Claim 4
Dependent Claim
34 words
A device for indicating the state of relaxation or tension of an individual in accordance with claim 1 wherein said temperature sensitive liquid crystals change colors depending upon the skin temperature of the individual.
Claim 5
Dependent Claim
35 words
A device for indicating the state of relaxation or tension of an individual in accordance with claim 1, further including a means provided on said planar surface sensitive to the ambient temperature of the surroundings.
Claim 6
Dependent Claim
43 words
A device for indicating the state of relaxation or tension of an individual in accordance with claim 1 further including a planar base member having a recessed frame around at least a portion of its periphery for insertion of said planar surface therein.
