    • A method and a device of enhancing data integrity using hash function for data transmission over an optical network are disclosed. The device includes a hash circuit, a lookup circuit, a vector circuit, and a correcting circuit. The hash circuit is capable of performing a hash function and configured to generate a hash value in response to a value of header error correction ("HEC") encapsulated in a gigabit passive optical network ("GPON") frame. The lookup circuit is capable of obtaining a data entry from a lookup table in a memory in accordance with the hash value. While the vector circuit generates an error vector in response to the data entry, the correcting circuit corrects an error or errors in the header portion of a data structure encapsulated in the GPON frame.

    • A method and apparatus for enhancing frame alignment using cyclic redundancy check (“CRC”) corrections are disclosed. In one embodiment, a process of frame alignment searches a predefined bit pattern within a first multi-frame structure and provides an assumed frame boundary after identifying the predefined bit pattern in the first multi-frame structure. While calculating a CRC value in response to the assumed frame boundary, the process further corrects the CRC value in accordance with a saved residue and F-bits identified by the assumed frame boundary. The assumed frame boundary is subsequently verified by comparing the calculated CRC value with embedded CRC value obtained from a second multi-frame structure.
    • 公开了一种使用循环冗余校验(“CRC”)校正来增强帧对准的方法和装置。 在一个实施例中,帧对齐的过程在第一多帧结构内搜索预定义的位模式,并且在识别出第一多帧结构中的预定义位模式之后提供假定的帧边界。 在响应于假定的帧边界计算CRC值时,该过程进一步根据保留的残差和由假定的帧边界识别的F比特来校正CRC值。 随后通过将计算的CRC值与从第二多帧结构获得的嵌入CRC值进行比较来验证假定的帧边界。

    • This present invention provides a bridge battery voltage equalizer to equalize the voltages of the serially connected battery strings, comprising at least one battery crossing over an energy-transferring circuit. A plurality of the energy-transferring circuits are interconnected in a bridge architecture. Each energy-transferring circuit having four nodes comprises a first semiconductor switch, a first diode, a second semiconductor switch, a second diode, and an inductor. One end of the first element switch is connected to a negative pole of the first diode thereto. A positive pole of the second diode is connected to one end of the second element switch thereto. The inductor is an energy storing element that crosses over between the negative pole of the first diode and the positive pole of the second diode.

    • A battery energy balance circuit and a battery charging bypass circuit is disclosed for batteries being charged at the same time to be charged equally. When the terminal voltages of the batteries are different, a controllable power device switch in the circuit switches on and off at a high frequency in order to reduce the input current to the batteries with higher terminal voltages and to increase the input current to the batteries with lower terminal voltages, achieving the goal of equal charging. The disclosed energy balance circuit can avoid damages to the batteries as a result of overcharging. When the number of batteries increases, one can expand the system in a modularized way to prevent inconvenience of circuit designs.
