Abstract: A method for switching shared content in a video conference includes determining a status of the video conference when a switch event is triggered. If the status is a video status, sharable content of the sharing terminal are detected, and whether the sharing terminal has at least one sharable content is determined. If so, one of at least one sharable content is shared with at least one remote terminal. If not, the status keeps being in the video status. If the status is a sharing status and the sharing terminal shares a content having a first index number, sharable content of the sharing terminal are detected, and whether the sharing terminal has a first sharable content having an index number larger than the first index number is determined. If so, sharing the first sharable content with at least one remote terminal by the sharing terminal.

Abstract: A mask management and bar code reading apparatus thereof are disclosed. The mask management method comprises providing a bar code reading apparatus, scanning a mask bar code on the mask by the bar code reading apparatus, transferring scanned information to a mask management system, producing a box bar code, moving the mask to a mask pod from a mask protective case, sticking the box bar code on the mask pod, inputting the data recorded in the box bar code into an exposure equipment, and exposing the mask by the exposure equipment. The bar code reading apparatus includes at least a clamping element to clamp the mask protective case, at least a reading head disposed on the clamping element to read a mask bar code, and a first light source providing a first light to irradiate the mask protective case to increase reading accuracy of the reading head.
