1. A temperature determination method, comprising:
- temporarily contacting a forehead of a subject with a first surface of a removable patch, and exposing a second surface of the patch opposite the first surface to ambient conditions;
sensing a temperature of the first surface of the patch while the first surface is in contact with the forehead at a first location thereon;
sensing a temperature of the second surface of the patch; and
calculating a sub-skull temperature of the subject, using a controller, based on the sensed temperatures of the first and second surface, wherein the calculated sub-skull temperature is based on an estimated thermal resistance of the subject'"'"'s skull and forehead skin, and wherein the thermal resistance is estimated based on at least one of an age, weight, and gender of the subject.

Abstract
A temperature determination method includes temporarily contacting a forehead of a subject with a first surface of a removable patch, and exposing a second surface of the patch opposite the first surface to ambient conditions. The method also includes sensing a temperature of the first surface of the patch while the first surface is in contact with the forehead at a first location thereon, sensing a temperature of the second surface of the patch, and calculating a sub-skull temperature of the subject based on the sensed temperatures of the first and second surface.

17. A temperature determination device, comprising:
-
a patch defining a first surface and a second surface opposite the first surface, the first surface removably attachable to a forehead of a subject; a first sensor positioned to detect a temperature of the first surface; and a second sensor positioned to detect a temperature of the second surface, wherein the device is configured to calculate a sub-skull temperature of the subject based on an estimated thermal resistance of the subject'"'"'s skull and forehead skin, and wherein the thermal resistance is estimated based on at least one of an age, weight, and gender of the subject. - View Dependent Claims (18, 19)

20. A temperature determination method, comprising:
-
removably attaching a first surface of a patch to a forehead of a subject, and exposing second and third surfaces of the patch opposite the first surface to ambient conditions, the second surface being separated from the first surface by a first patch thickness, and the third surface being separated from the first surface by a second patch thickness different than the first thickness; sensing a temperature of the second and third surfaces while the first surface is attached to the forehead; and calculating a sub-skull temperature of the subject, using a controller, based on the sensed temperatures of the second and third surfaces, and an estimated thermal resistance of the subject'"'"'s skull and forehead skin. - View Dependent Claims (21, 22)

23. A temperature determination method, comprising:
-
temporarily contacting a forehead of a subject with a first surface of a removable patch, and exposing a second surface of the patch opposite the first surface to ambient conditions; sensing a temperature of the first surface of the patch while the first surface is in contact with the forehead at a first location thereon; sensing a temperature of the second surface of the patch; sensing a blood flow metric, the metric indicative of blood flow at the forehead skin proximate the first surface, and comparing the sensed metric to a predetermined metric threshold; and calculating a sub-skull temperature of the subject, using a controller, based on the sensed temperatures of the first and second surface. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31)
