Non-invasive temperature measurement
First Claim
1. A thermometric device, comprising:
- a probe, comprising;
a membrane configured to be applied to an external surface of a body of a subject; and
one or more temperature sensors located within the probe in thermal contact with the membrane; and
a processing unit configured to receive temperature readings from the one or more temperature sensors, to determine time-dependent parameters of temperature change responsively to the temperature readings, to calculate a local temperature of the body using a function comprising the time-dependent parameters, and to calculate a core body temperature by correcting for a difference between the core body temperature and the local temperature.

Abstract
A thermometric device includes a probe having a membrane configured to be applied to an external surface of a body of a subject and one or more temperature sensors located within the probe in thermal contact with the membrane. A processing unit is configured to receive temperature readings from the one or more temperature sensors, to determine time-dependent parameters of temperature change responsively to the temperature readings, to calculate a local temperature of the body using a function including the time-dependent parameters, and to calculate a core body temperature by correcting for a difference between the core body temperature and the local temperature.

22. A method for thermometric measurement, comprising:
-
applying a probe, which comprises a heat-conducting membrane and one or more temperature sensors in thermal communication with the membrane, to an external surface of a body of a subject; receiving temperature readings from the one or more temperature sensors while the probe is applied to the surface of the body; determining time-dependent parameters of temperature change responsively to the temperature readings; calculating a local temperature of the body using a function comprising the time-dependent parameters; and calculating a core body temperature by correcting for a difference between the core body temperature and the local temperature. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
