  • Signal converter for an all-in-one USB connector that includes USB 2.0, USB 3.0 and eSATA
    Patent number: 7921233
    Abstract: A signal converter is used to connect between an all-in-one USB connector and a PCB and has USB 3.0 and eSATA signal interfaces, an inner communication interface and a processing unit. The processing unit has an identifying and converting procedure. The identifying and converting procedure is periodically executed to detect the USB 3.0 and eSATA signal interfaces in sequence and determine whether a response signal is sent back from one of the USB 3.0 and eSATA signal interfaces. If a determined result is positive, the processing unit bi-directionally converts two different standard signals of the inner communication interface and the one of the USB 3.0 and eSATA signal interfaces that transmitted the response signal. Therefore, the PCB successfully communicates with the external electronic device through the correct port of the all-in-one USB connector.

  • Heat sink having enhanced heat dissipation capacity
    Patent number: 7916484
    Abstract: A heat sink includes a metallic heat conducting layer, a non-metallic heatsink layer combined with the metallic heat conducting layer and having a porous structure, and a hollow receiving space defined between the metallic heat conducting layer and the non-metallic heatsink layer. Thus, the heat produced by a heat source is conducted quickly and distributed evenly on the metallic heat conducting layer to form an evenly heat conducting effect, while the hollow receiving space has a heat convection effect to quickly transfer the heat on the metallic heat conducting layer to the non-metallic heatsink layer which produces a heatsink effect to dissipate the heat so that the heat is dissipated quickly by provision of the metallic heat conducting layer, the hollow receiving space and the non-metallic heatsink layer.
