An expansion ratio detection system for rubber, including a controller, a rubber sampling module, a rubber calender, a temperature control module, and an expansion ratio detection module. The rubber sampling module obtains a rubber to be tested consistent with a weight value. After the temperature control module determines that the rubber to be tested has reached a first temperature value, the rubber calender outputs the rubber to be tested having a thickness value. The expansion ratio detection module obtains an expansion ratio according to twice the thickness value and a roller pitch.

A microwave radiometric sensor probe module configured to fit within at least an external portion of an auditory or ear canal of a patient encloses a microwave integrated circuit and associated waveguide printed probe. The probe is configured to receive microwave radiation from a dielectric rod antenna of the module oriented into the auditory canal towards a tympanic membrane. Radiation from the tympanic membrane is coupled into the rod antenna, projected towards the printed probe, and received at the integrated circuit. A communications interface connects the integrated circuit to a temperature monitor and control unit for receiving the sensor output and for deriving at least a measure of patient brain temperature from the sensor output. The temperature monitor and control unit may be connected to a targeted temperature management system for controlling the temperature of a patient on the basis of the derived brain temperature.

A fluid temperature sensor may include a housing having an inlet, an indicator coupled to the housing, and a container disposed within the housing. The container may include a thermo-sensitive housing containing a thermal sensing element. The thermal sensing element may be configured to expand in response to reaching a threshold temperature thereby moving the container from a closed position to an open position. Fluid may flow through the inlet and fill the housing in the open position of the container to actuate the indicator into an activated position.
