  • Publication number: 20180317325
    Abstract: A circuit board with conductive wiring which is precisely shaped and sized includes a two-part conductive element, namely a first conductive wiring layer and a second conductive wiring layer. The first conductive wiring layer and the second conductive wiring layer are in direct contact to each other. A projection of the first conductive wiring layer along a direction perpendicular to the circuit board and a projection of the second conductive wiring layer totally cover each other.

  • Publication number: 20180253241
    Abstract: Systems and methods for saving critical data upon power loss are described. In one embodiment, the systems and methods include performing a write operation to a first track of a storage drive, monitoring a voltage level of a storage drive to detect power loss on the storage drive while performing the write operation, identifying a track ID of a second track adjacent to the first track upon detecting power loss on the storage drive, and storing the identified track ID in a non-volatile memory on the storage drive.

  • Publication number: 20180139842
    Abstract: A printed circuit board with high-capacity and high-current copper circuit includes a conductive trace, a first protecting layer, and a second protecting layer on opposite sides of the conductive trace. The conductive trace includes a basic conductive trace pattern, a first conductive trace pattern, and a second conductive trace pattern. The first and second conductive trace patterns are directly formed on opposite surfaces of the basic copper conductive trace pattern. A width of trace of the first conductive trace pattern is the same as a line width of the second conductive trace pattern.

  • Patent number: 9880857
    Abstract: A method or system comprises reading content of a plurality of system files from storage media of a storage device, generating a master storage device system file, and storing the master storage device system file on the storage media at a master system file location. The location of the master system file is provided to boot firmware or hardware. As a result, when the system boots up, the master system file is read into a temporary cache.
