  • Publication number: 20130051504
    Abstract: A compensating device for detecting and compensating for a sampling clock offset in a receiver. An SCO detector includes multiple calculation paths and a controller. Each calculation path receives a time domain signal and a hypothetic offset, calculates correlation coefficients between the time domain signal and a delayed version of the time domain signal according to a predetermined delay and the hypothetic offset, calculates correlation coefficient sums according to the correlation coefficients, and extracts a maximum correlation coefficient sum for the hypothetic offset from the correlation coefficient sums. The controller is coupled to the calculation paths for providing different hypothetic offsets to each calculation path and detects the SCO according to the maximum correlation coefficient sums obtained from the calculation paths. An SCO compensator receives the SCO and compensating for the SCO on a signal generated in a signal processing path of a receiver.

  • Patent number: 8320123
    Abstract: An electronic device includes a first housing, a first pivoting mechanism disposed on a side of the first housing, a second housing, a second pivoting mechanism disposed on a side of the second housing, and a bridging component. A first end and a second end of the bridging component are respectively pivoted on the first pivoting mechanism and the second pivoting mechanism. The bridging component includes a first contacting portion for contacting against the side of the first housing when the first pivoting mechanism pivots on the first end so that the first housing rotates around the second housing at a first angle, and a second contacting portion for contacting against the side of the second housing when the second end pivots on the second pivoting mechanism so that the first housing rotates around the second housing at a second angle greater than the first angle.

  • Publication number: 20080237321
    Abstract: A storage box includes a flexible box body, a hard support board removably mounted in the box body to support the box body, and a cover removably mounted on the box body. The support board is receivable into the cover, and the box body is foldable when being compressed and receivable into the cover. Thus, the support board and the box body are received in the hollow inside of the cover to reduce the volume of the storage box to the minimum size so that the storage box has a smaller volume when not in use, thereby greatly saving the space of storage, and thereby facilitating packaging, storage and transportation of the storage box.

  • Publication number: 20050268029
    Abstract: An optical disc drive includes a microprocessor, a control IC, an RF IC, and an interface unit. The microprocessor is electrically coupled to the control IC. The control IC is electrically coupled to the RF IC, a volatile RAM, an optional non-volatile ROM, and to a bus interface for communications with an external host. The interface unit is electrically coupled to the bus interface. Initialization of the optical disc drive is performed using initialization data stored in a non-volatile manner in the ROM, if present, or downloaded from the host if the ROM is not present. After the initialization, the interface unit signals an application program in the host to download the optical drive's operational firmware and writes received data into the RAM. The microprocessor is initialized with the operational firmware's starting address and the microprocessor executes the downloaded operational firmware. The ROM may also store read operation firmware to enable the optical disc drive to read data stored in the disc.
