Abstract
A method and system for the wireless interrogation of a body immersed in a circulatory bath or a tank for heating. More specifically, the system may include a probe having multiple sensors for gauging a core temperature associated with the immersed body in combination with one or more wireless connections leading to a controller (on a circulator or a user interface) such that the user can determine temperature information (e.g., core temperature) of the body being immersed.
Claims3
A probe and interrogator assembly for monitoring temperature data of at least the interior of a body in a bath, the assembly comprising:
- a) an interrogator comprising:
- i) a controller;
- and
- ii) a transceiver, the transceiver including a plurality of continuous loops rotationally and orthogonally displaced from one another for transmitting a very low frequency signal for powering a remote probe and receiving temperature data from the remote probe;
- and
- b) a probe assembly for providing body temperature data to a remote interrogator outside of a bath containing the body, the probe assembly comprising:
- i) a rigid member having a first end, a second end, and a shaft extending therebetween,
- ii) a first sensor at the first end for providing temperature data related to the interior of the body;
- iii) an antenna at the second end of the rigid member for providing temperature data in response to an interrogation very low frequency signal transmitted by the remote interrogator through the bath;
- and
- iv) a chip on the second end for receiving temperature data from the first sensor, the chip storing said temperature data to provide to the antenna in response to the interrogation very low frequency signal, and the chip receiving power via the interrogation very low frequency signal.
