OBJECTIVE: A remote multi-part personal radiation dose detection system is designed with ATmega32A single chip microcomputer as the control core. METHODS: First of all, the geiger counter tube module collects the radiation signal of the surrouding environment. Secondly, using ATmega32A Microprocessor of Slave computer to calculate the collected signal. Finally, it is sent to the host receiving device or mobile APP through Bluetooth module,so as to realize real-time detection of radiation data, remote transmission and security alarm. RESULTS: The system is measured in the same environment as the RG1100 radiometer, with a maximum difference of 0.03 μSv/h.This shows that it can stably realize the functions of radiation measurement, monitoring, alarm, remote connection and multimodal display. CONCLUSIONS The system has the advantages of good portability (easy to carry), low power consumption, accurate measurement and so on. It has certain reference value and practicability.

OBJECTIVE: Based on the TGAM PCB module, a system of emotion control using audio-visual feedback is designed. METHODS: TGAM collects EEG information through the electrode in contact with the forehead skin. The system analyzes the user's emotion through the STM32F103ZET6 of the main control chip, and finally controls the control end of the system to regulate the user's emotion. RESULTS: It can be seen from the test results that the system can precisely recognize the user's emotions, and at the same time effectively adjust the user's emotions from both audio-visual aspects. CONCLUSIONS The system has high recognition accuracy and good adjustment effect.
