Abstract: A speed measurement system with dynamic image capture includes a dynamic camera, a velocimeter and an image combining unit. The dynamic camera is adapted to continuously shoot a predetermined region to capture a first dynamic image. The velocimeter is adapted to measure a moving speed of a moving object in the predetermined region. The image combining unit is adapted to combine the first dynamic image and the moving speed of the moving object into a second dynamic image. The speed measurement system with dynamic image capture achieves a speed measurement function and a dynamic image capture function. Further, a speed measurement system with static image capture is also provided.

Abstract: An ink filling structure includes a case, a guiding element received in the case for controlling flowage of the ink, a washer positioned between the guiding element and the case, and an elastic element connecting with the guiding element for providing the guiding element with an elastic force to push the guiding element to a predetermined position. When the guiding element is located at the predetermined position, the guiding element prevents the ink from reflowing; while the guiding element is located at other positions, the ink can reflow.

Abstract: This invention is directed to a monitor system (1). The monitor system includes a monitor controller (10), at least one video server (141), at least one video camera set (151), and at least one microphone (161). The monitor controller and the at least one video server are connected to different power line LAN switches, respectively, which will achieve the purpose of exchanging data via a power line LAN.
