Abstract:
An expansion device includes a peripheral component interconnect (PCI) card, a hard disk connector, a hard disk drive (HDD), and a signal converter. The PCI card includes PCI pins for connecting to a PCI slot of a motherboard of a computer. The connector is arranged on the PCI card. The HDD is attached to the PCI card and connected to the connector. The signal converter is connected between the hard disk connector and the PCI pins. The signal converter receives a PCI signal from the PCI slot through the PCI pins, and converts the PCI signal to a signal suitable for and provided to a HDD through the connector. When the HDD completes reading and writing, the signal converter receives a feedback signal from the HDD through the connector, and converts the feedback signal to a PCI signal for being provided to the motherboard through the PCI pins.
Abstract:
A heat dissipation assembly for dissipating heat from a heat-generating component includes a first heat sink mounted on the heat-generating component for dissipating heat therefrom, and a second heat sink movably mounted to the first heat sink, to be adjustable relative to the first heat sink. The second heat sink can be moved to a desired position to fit a need of heat dissipation.
Abstract:
A power saving device includes a first power connector adapted for connecting to a power source, a second power connector adapted for connecting to a power wire of a display, an infrared sensor, an infrared coupling circuit, a wave shaping circuit, and a switch circuit connected between the first and second power connectors. The infrared sensor senses user status and initiates a user status signal. The wave shaping circuit receives the user status signal via the infrared coupling circuit and converts the user status signal to a voltage signal. The switch circuit receives the voltage signal and converts the voltage signal to a control signal to control the connection between the first power connector and the second power connector.
