  • HDD anti-shock and anti-vibration device
    Patent number: 7660107
    Abstract: A Hard Disk Drive anti-shock and anti-vibration device and a Data Storage Device consisting of a HDD and the HDD anti-shock and anti-vibration device are described. The HDD anti-shock and anti-vibration device includes a packaging paper and foam. The foam is adhered on the packaging paper. When this packaging paper, with the foam adhering onto it, is folded, it can wrap the HDD in the foam. This HDD anti-shock and anti-vibration device can prevent the HDD from damage when the HDD is accidentally dropped or bumped and has excellent anti-shock and anti-vibration effects.

  • System and method of scaling images using adaptive nearest neighbor
    Patent number: 7142729
    Abstract: A method for interpolating a target pixel from a plurality of source pixels in a high contrast image. The method comprises the following steps. A window of the plurality of source pixels is examined and compared with a plurality of predefined conditions for determining if a structure of significance is present within the window. A filter configuration is selected from a plurality of filter configurations in accordance with results of the comparison. The selected filter is applied to the source pixels for interpolating the target pixel. If the structure of significance is detected in the window, the selected filter best preserves the structure.
