TEMPERATURE MEASURING DEVICE Russian patent published in 2017 - IPC G01K7/00 

FIELD: measuring equipment.

SUBSTANCE: temperature measuring device is proposed, which contains an indicating unit, a reset button and a series-connected temperature sensor and a frequency converter, a register and a signal comparison circuit, one input of which is connected to the output of the recorder, the other - to the output of the register, and the output - to the control input of the register, the setting input of which is connected to the "Reset" button. The output of the recorder is connected to the input of the register connected by the output to the input of the display unit. The device is additionally equipped with a Schmidt trigger, a pulse generator and a logic circuit AND. The outputs of the Schmidt trigger of the pulse generator and the frequency converter are connected to the inputs of the circuit AND, the output of which is connected to the input of the recorder, and the Schmidt trigger input is connected to the output of the temperature sensor and the input of the frequency converter. The use of the Schmidt trigger made it possible to establish the possibility of a constant start of the patient's temperature measurement from a certain predetermined minimum value, and the use of the low-frequency self-oscillator made it possible to perform a temperature measurement cycle while the temperature sensor is at the patient and to record the maximum temperature during the measurement cycle.

EFFECT: increasing the accuracy of the device.
