APPARATUSES FOR NON-INVASIVELY SENSING INTERNAL TEMPERATURE
First Claim
1. A transducer for noninvasively measuring temperature within a body of a subject, comprising:
- a circuit board including a front side and a back side opposite from the front side, the circuit board defining an antenna for receiving at least one native temperature signal from a location of interest within a body of a subject;
a reference temperature sensor; and
a coaxial cable connector comprising a frequency-division multiplexer for transmitting a multiplexed signal including an intermediate temperature signal from the antenna and a reference temperature signal from the reference temperature sensor.

Abstract
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.
