Abstract: A water quality monitoring system is provided, including several sensors, several actuators, and an embedded system. The sensors sense environmental parameters and separately output a plurality of sensing signals including the environmental parameters. The actuators change the environmental parameters. The embedded system includes a storage module, a data collection module, a data analysis module, and a control module. The storage module stores a plurality of normal parameter ranges that correspond to the respective environmental parameters. The data collection module is connected to the sensors for receiving the sensing signals. The data analysis module is connected to the storage module and the data collection module to determine whether the sensing signals are abnormal according to the normal parameter ranges and output a determination result. The control module is connected to the data analysis module to control the actuators or output a warning signal according to the determination result.

Abstract: A transmission system includes a first security unit coupling to application ends, a second security unit coupling to a user end, and a server. The server sends a first attribute key to the first security unit based on attributes of the application ends and sends a second attribute key to the second security unit based on attributes of the user end. To enable one application end, the first security unit encrypts a session key with the first attribute key, opens a socket, and sends the encrypted session key to the server. When the second security unit receives a request for the application end, the server sends the encrypted session key to the second security unit. The second security unit decrypts the encrypted session key with the second attribute key and connects to the socket. The second security unit interchanges information with the first security unit via the session key.

Abstract: A laser soldering system using dynamic light spot and a method thereof are provided. A laser module is controlled to radiate toward multi-lens to form a light spot on a soldering target for soldering, and a lens distance between the multi-lens is adjusted to adjust a light spot size. The disclosure may provide multiple heating densities respectively adequate to different soldering status via adjusting the light spot size when using same laser power, so as to improve the soldering quality.
