Abstract: The embodiments of the present application provides a method and apparatus for preventing heat damage to a thermal imaging camera. The method includes: obtaining a thermal imaging picture of the thermal imaging camera; detecting whether the thermal imaging picture shows that a high-temperature object appears in the picture of the thermal imaging camera; confirming that the thermal imaging picture shows that a high-temperature object appears in the picture, generating a heat damage alarm signal, and closing a baffle if the baffle is not closed currently. In the present application embodiments, after detecting a heat damage alarm signal, that is, after detecting that a high-energy radiating object enters an image picture, the baffle is closed immediately, thereby avoiding the risk of the sensor being permanently burnt due to directly face to the high-energy radiating object.

Abstract: A computer system includes a desk, and a first display and a first keyboard arranged on a desk panel of the desk and flexibly connected to the desk panel. The panel board includes at least two layers; an edge of a top layer of the panel board is flexibly connected to a second layer of the panel board; a lower surface of the top layer of the panel board is used as a second display and an upper surface of a second layer of the panel board is used as a second keyboard; and the first display, the first key board, the second display, and the second keyboard are all connected to the computer. The computer system of the present disclosure effectively protects eye sights, reduces the probability of shortsightedness, greatly increases the amount of exercise, consumes unnecessary energy, reduces the storage of energy and production of fat, further results in loss of weight, and at the same time strengthens physical exercise and improves health states.

Abstract: The present disclosure provides an English training method, including the following steps: classifying and storing words according to predetermined word classification rules; receiving a user command for extracting a corresponding word according to a classification of the word, and extracting the corresponding word according to the user command and outputting the word in audio or video form; the word classification rules including: combining two consonants with five vowels a, e, i, o, and u respectively to form words; or using a main word or a transformation of the main word as a main body, and combining the main body with 26 letters of the English alphabet in sequence to form words; or combining the five vowels a, e, i, o, and u with other letters of the English alphabet to form word roots, and combining each of the word roots with the 26 letters of the English alphabet in sequence to form words; or matching a whole English sentence or a whole English paragraph with a Chinese song; or noting a pronunciation
