Apparatuses for non-invasively sensing internal temperature
A transducer for noninvasively determining an internal temperature of a location of interest in a body of a subject is provided. The transducer receives a native temperature signals originating from the location of interest without substantially receiving interfering signals, and includes one or more shielding features for preventing interference. In addition, such a transducer may include a dielectric cavity configured or positioned to increase the native temperature signals sensed, or received, by the antenna. A transducer may be configured to multiplex signals indicative of a temperature of a location of interest within the body of a subject and reference temperature signals. Such a transducer may include a connector that facilitates the communication of a multiplexed signal, such as a connector for a coaxial cable. The connector of a transducer may be configured to swivel relative to an end of a cable.

G01K 13/00 - Thermometers specially adapted for specific purposes
Apparatuses and systems for determining a temperature of a targeted subject are disclosed. A temperature sensing system may include an antenna for sensing electromagnetic radiation (e.g., microwaves, etc.) emanating from the source. Based on that electromagnetic radiation, the antenna generates a temperature signal. A switch, which is located at or adjacent to an output of the antenna, receives the temperature signal, as well as a reference signal from a termination. The temperature signal and the reference signal are conveyed along a cable to a signal converter. Signal-altering events that affect the temperature signal as it is conveyed also affect the reference signal. Thus, any error caused by a signal-altering event automatically cancels out. The signal converter measures or otherwise processes the temperature signal and, since there is no need to correct for errors in the temperature signal, the reference signal, and accurately calculates the temperature of the source.

A system for and noninvasively monitoring temperature within a body of a subject includes a transducer and an interface component. The transducer receives native temperature signals, which are electromagnetic signals. One or both of the transducer and the interface component convert the native temperature signals to a standard temperature signal. The interface unit may be configured to be coupled to a standard temperature signal-receiving apparatus, such as a standard vital signs monitor or a standard body temperature management system, which may recognize the standard temperature signal. Methods for noninvasively monitoring temperature, including receiving native temperature signals and converting the native temperature signals to a standard temperature signal, are also disclosed.
