Abstract: The present invention relates to a cursor control system, including a first electronic device, a second electronic device, and a mouse. The mouse is wirelessly connected to the first electronic device and the second electronic device and may move a cursor on a first working desktop corresponding to the first electronic device or a second working desktop corresponding to the second electronic device. When receiving a drive signal from the mouse, the first electronic device displays a jump image on the first working desktop. When the cursor is moved to the jump image, the mouse may transmit a switching signal to the second electronic device according to a masking signal from the first electronic device, so that the second electronic device can display the cursor on the second working desktop.

Abstract: A vehicular projection system includes plural information collectors, a time-division multiplexing device and a projection mechanism. The plural information collectors are used for outputting driving information. The time-division multiplexing device includes plural wireless transmission modules. The time-division multiplexing device determines the transmitting sequence of plural information collectors according to the receiving sequence of wireless transmission requests from the plural information collectors. Moreover, the time-division multiplexing device determines the suitable wireless transmission modules according to the file properties of the driving information and the wireless transmission capabilities of the plural information collectors. Since the plural information collectors can simultaneously transmit driving information to the time-division multiplexing device through different wireless transmission modules, the wireless transmission efficiency is enhanced.

Abstract: A cursor control system includes a cursor control device and a computer host. The cursor control device includes an operating plate, a blood vessel sensing unit, and a controlling unit. The operating plate is used for placing a palm and a finger of a user thereon. The blood vessel sensing unit is used for detecting the finger at different positions, thereby acquiring plural blood vessel images of the finger. According to the plural blood vessel images, a finger displacement amount is acquired by the controlling unit. In addition, a cursor moving signal corresponding to the finger displacement amount is transmitted from the controlling unit to the computer host. According to the cursor moving signal, the cursor is correspondingly moved.

Abstract: A data report rate adjustment method for use between a computer host and a peripheral device is provided. According to the actual workload level of the computer host and/or the amount of the input data of the peripheral device, the priority or the report rate of the data to be transmitted from the peripheral device can be dynamically adjusted or set. More especially, the unnecessary data report can be avoided. Consequently, the workload of the computer host can be effectively reduced, and the power consumption of the peripheral device can be saved.

Abstract: A desktop controlling method is provided. The desktop switching function is selectively enabled according to the result of detecting whether a cursor is located at a border of the current desktop and the result of detecting whether a desktop switching signal. Consequently, the desktop switching function can be achieved through the mouse only. That is, it is not necessary to operate both of the mouse and the keyboard to achieve the desktop switching function. Moreover, the background colors of the virtual desktops can be set by the user according to the practical requirements. Consequently, the virtual keyboard to be switched can be easily recognized by the user.

Abstract: A car seat with a warning function includes a seat body having a seat cushion, plural adjusting posts, a wireless transmission module, a control unit and a warning element. The wireless transmission module is in wireless communication with an electronic device. When the adjusting posts are pushed by the seat cushion, the lengths of the adjusting posts are changed. If the control unit receives a body curve data from the electronic device and judges that the body curve data complies with a predetermined body data, the control unit changes the lengths of the adjusting posts according to the body curve information. Consequently, the shape of the seat cushion fits the body shape of the user. If the control unit judges that the body curve data does not comply with the predetermined body data, the control unit controls the warning element to output a warning signal.
