Abstract: A KVM switch system capable of communicating with a selected computer through a single cable is disclosed. Between the computer and the KVM switch system, keyboard/mouse data is transmitted and video data is received through a single cable. The KVM switch system includes a protocol controller, a graphic controller, a switch and a plurality of transceivers. The KVM switch system is coupled to plural computers. The protocol controller transforms keyboard/mouse signals into the keyboard/mouse data in a protocol standard and transforms the video data in the same protocol standard into video signals. The graphic controller receives the video signals from the protocol controller and transmits the video signals to a display. The switch routes the keyboard/mouse data and the video data according to a processor of the KVM switch system.

Abstract: The present invention discloses a cooling device using thermal-conductive liquid. The present invention includes a base, a means for generating magnetic field and a plurality of thermal-conductive fins. Among these, the base includes a circuit pipe accommodating a magnetized thermal-conductive liquid. The means for generating magnetic field is positioned in the base and used to generate a magnetic field. The thermal-conductive fins are formed on the base and the surround the circuit pipe. The magnetic field generated by the means for generating magnetic field makes the magnetized thermal-conductive liquid flows so as to dissipate heat.
