Abstract
Official abstract text for this publication.
A method of controlling transfer of heat to skin during a shaving stroke. A shaving razor system with a heating element is provided. An insulating member for delivering heat to the heating element is provided. A temperature of a first area of the heating element is measured with a first thermal sensor. A temperature of a second area of the heating element is measured with a second thermal sensor. Power to the insulating member is decreased when an average temperature sensed by the thermal sensors is greater than or equal to a first predetermined temperature. Power to the insulating member is decreased when an individual temperature sensed by either of the thermal sensors is greater than or equal to a second predetermined temperature.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of controlling transfer of heat to skin during a shaving stroke, said method comprising: providing a shaving razor system comprising a heating element, providing an insulating member for delivering heat to the heating element; measuring a temperature of a first area of the heating element with a first thermal sensor; measuring a temperature of a second area of the heating element with a second thermal sensor; switching power to the insulating member off when an average temperature sensed by the thermal sensors is greater than or equal to a first predetermined temperature; and switching power to the insulating member off when an individual temperature sensed by either of the thermal sensors is greater than or equal to a second predetermined temperature, wherein the first predetermined temperature is different than the second predetermined temperature. 2. The method of claim 1 wherein the first predetermined temperature is about 46 degrees Celsius to about 50 degrees Celsius. 3. The method of claim 1 wherein the second predetermined temperature is about 50 degrees Celsius to about 60 degrees Celsius. 4. The method of claim 1 wherein the first predetermined temperature is less than the second predetermined temperature by at least 2 degrees Celsius.
