Abstract: An in-vehicle computer includes a computer casing, a filtering structure, and a fan. The computer casing has a casing accommodating space and a vent opening communicating with the casing accommodating space. The filtering structure is detachably disposed at the vent opening. The fan is disposed in the casing accommodating space and spaced from the vent opening. A suction port of the fan is toward the vent opening. The fan generates an airflow, for dissipating heat from an electronic component in the casing accommodating space. By the filtering effect of the filtering structure, the particle amount in the airflow can be reduced. A vehicle includes a vehicle cage and the in-vehicle computer, disposed in the vehicle cage. The vent opening communicates with the cockpit space of the vehicle cage, so that the fan can draw lower-temperature air for enhancing the heat dissipation efficiency.

Abstract: A mouse is used for a computer having data. The mouse includes a data saving module, a pointing module, a wireless communicating module and a control module. The pointing module detects a position of the mouse to generate an input message. The wireless communicating module communicates with the computer via a wireless transmission protocol. The control module electrically connects with the data saving module, the pointing module and the wireless communicating module, and is able to control the wireless communicating module to send the input message to the computer, to receive the data from the computer via the wireless communicating module and save the data to the data saving module, or to send the data stored in the data saving module to the computer.
