  • Patent number: 10111139
    Abstract: The present invention relates to an offline-operable wireless network system and the method for operating the same. When a wireless base station is not connected to the evolved packet core (EPC) server, the wireless base station will emulate the EPC server. Thereby, the electronic device connected with the wireless base station can be connected to the emulated EPC server, so that the wireless network functions still can be applied in the offline state and a wireless local area network can be further built.

  • Patent number: 8332608
    Abstract: For decreasing seeks generated when switching an execution flow between commands to enhance read and write performances of a disc drive, a command is implemented with a specifically-designed data structure, and commands having neighboring physical addresses and the same type of read or write operations are grouped and linked together. With the aid of command groups, seeks between commands are significantly decreased, though starvation may arise. A few techniques are further provided for preventing starvation of command groups and for preserving the benefits of decreasing seeks.

  • Patent number: 8214716
    Abstract: A method for processing noise interference in a serial advanced technology attachment (SATA) interface. In the method, when a receiver does not receive a SOF primitive (start of frame primitive) but does receive an EOF primitive (end of frame primitive) or WTRM primitive (wait for frame termination primitive), the receiver outputs a R_ERR primitive (reception error primitive) to enable a transmitter to resend original data and thus to eliminate the interference. In addition, if the transmitter detects an error during the data transmission, a HOLD primitive (hold data transmission primitive) will be issued to temporarily stop the data transmission.

  • Patent number: 8086938
    Abstract: A method for processing noise interference in a serial AT Attachment (SATA) interface. The method includes the steps of detecting whether there is an error in CRC (Cyclic Redundancy Check) checksum or whether an R_ERR primitive (reception error primitive) is received, detecting whether a FIS (Frame Information Structure) is a data type if there is any error and returning back to error state detecting step if there is no any error, detecting whether the FIS is a ATAPI packet command CDB (Command Descriptor Block) when the FIS is the data format, and writing a special tag to the CDB and returning back to the error detecting step.

  • Patent number: 7665011
    Abstract: A method and circuit for reducing SATA (Serial Advanced Technology Attachment) transmission data errors by adjusting the period of sending two consecutive ALIGN Primitives. The method reads a counting value of an 8b/10b coding error counter at a predetermined period and adjusts the period of sending two consecutive ALIGN Primitives according to the counting value. Because the system dynamically adjusts the period of sending two consecutive ALIGN Primitives according to the channel condition, the SATA transmission data errors can be reduced.
