  • Patent number: 11995471
    Abstract: A resource integration method includes the following steps: a receiving module receives access information from a guest operating system on the host device; the access information is used to determine whether the frame rate is lower than a frame rate threshold; when the receiving module determines that the frame rate is lower than the frame rate threshold, the receiving module transmits an external resource request signal to the receiving module; after the receiving module receives the external resource request signal, a resource management module (which is located in the bridge module) selects an optimal external device from a specific category (among a plurality of categories in a candidate list), and a calculation operation or a storage operation corresponding to the specific category is transmitted to the optimal external device for calculation or storage by the bridge module.

  • Patent number: 7525242
    Abstract: A lamp clamping and electrically connecting device includes a base, two flexible portions and two protrusions. The flexible portions are interspaced to be disposed on the base. The protrusions are correspondingly disposed on the inner sides of the flexible portions. In a natural state, the gap between the protrusions is smaller than the diameter of an electrode end of a lamp. When the electrode end is moved towards the base in the gap between the protrusions, the electrode end presses the protrusions so that the flexible portions swing outwardly. When the electrode end touches the base, the protrusions are restored to the natural state, so that the protrusions and the base clamp the electrode end, and that the electrode end is electrically connected to the device.

  • Publication number: 20080151135
    Abstract: A common voltage adjustment apparatus for adjusting a common voltage of a liquid crystal display (LCD) panel includes a data-read-write circuit and an output circuit. The data-read-write circuit includes a one-time-programmable (OTP) memory module and a control interface unit. The OTP memory module includes several OTP memories. The control interface unit outputs common-voltage-setting data according to a control signal and selectively stores the common-voltage-setting data into an unwritten OTP memory in the OTP memory module. The output circuit includes a reference-voltage generator and a digital-to-analog converter (DAC). The reference-voltage generator generates a reference voltage. The DAC converts the common-voltage-setting data into an output voltage according to the reference voltage.
