Abstract: A method of monitoring an internal body temperature of a patient includes detecting a skin temperature of the patient using a temperature sensor in a body-mountable temperature monitor attached to the patient; calculating, using the temperature sensor, a heat flux associated with the body-mountable temperature monitor based on selectively activating a heater in the body-mountable temperature monitor; and determining the internal body temperature of the patient using the skin temperature and the heat flux.

Abstract: An adhesive layer applicator for a body-mountable device is disclosed. The applicator includes a housing defining a first opening through which a chamber is accessible, and a plurality of adhesive layers and a plurality of adhesive liners alternately stacked on a floor that is movable within the chamber. The size and shape of the opening corresponds to the size and shape of the body-mountable device. The housing is configured to receive at least a portion of the body-mountable device through the opening. A second opening is formed in each adhesive layer in the plurality of adhesive layers and a gel is accommodated within the second openings.

Abstract: Various methods and devices for reducing the time for a body-mountable temperature monitoring device to provide an accurate body temperature are disclosed. Methods are used to accurately predict the measured temperature once the monitoring device reaches thermal equilibrium. For example, in one embodiment, a method for measuring body temperature of a subject includes obtaining, by a temperature monitor attached to a body of the subject, a plurality of body temperature measurements at a plurality of times, determining parameters of a model used for predicting temperature based on the plurality of measurements, predicting a body temperature of the subject based on the model, and outputting the predicted body temperature as a current temperature reading.

Abstract: The technology described herein relates to body mountable thermal coupling devices and, more specifically, to body mountable thermal coupling apparatuses with resistance to varying ambient conditions. In some implementations, a body mountable thermal coupling apparatus is disclosed. The apparatus includes a bio-compatible thermally conductive metal disc, a substrate, a thermal sensor, an enclosure, and an adhesive patch. The described apparatus facilitates enhanced thermal coupling between a heat source, e.g., human skin, and a thermal (or temperature) sensor.
