    • A battery over-current protection controller includes a current sense circuit, a first pin coupled to one end of the current detection circuit, a second pin, and a third pin. The second pin and the third pin are respectively coupled to a positive end and a negative end of a battery module. The current sense circuit includes a reference voltage generation unit, a voltage dividing unit, and a comparison unit. The reference voltage generation unit is coupled between the second pin and the third pin to generate a reference voltage. The voltage dividing unit has one end coupled to the reference voltage to thereby generate a voltage dividing signal. The comparison unit receives the voltage dividing signal and a current detection signal indicative of a value of a current flowing through the current detection circuit to thereby generate an over-current protection signal when the current is greater than the predetermined current.
    • 电池过流保护控制器包括电流检测电路,耦合到电流检测电路的一端的第一引脚,第二引脚和第三引脚。 第二引脚和第三引脚分别耦合到电池模块的正端和负端。 电流检测电路包括参考电压产生单元,分压单元和比较单元。 参考电压产生单元耦合在第二引脚和第三引脚之间以产生参考电压。 分压单元具有耦合到参考电压的一端,从而产生分压信号。 比较单元接收分压信号和指示流过电流检测电路的电流值的电流检测信号,从而当电流大于预定电流时产生过电流保护信号。

    • A method and system is provided for encrypting an image compressed with a JPEG2000-based compression with minimal overhead so that the encrypted codestream is compliant with the syntax of the JPEG2000-based compression and can be scaled without decrypting. The encryption system generates, for each independent encryption segment of a codestream for an image, a unique initialization vector from a global initialization vector in such a way that the initialization vectors can be generated during decryption from the global initialization vector, even after truncation. The encryption system encrypts each independent encryption segment using its unique initialization vector. The encryption system ensures that the encrypted codestream is compliant with the syntax of the JPEG2000-based compression both as originally generated and as truncated by an encryption-unaware device.
    • 提供了一种方法和系统,用于以最小的开销加密用基于JPEG2000的压缩压缩的图像,使得加密的码流符合基于JPEG2000的压缩的语法,并且可以在不进行解密的情况下进行缩放。 加密系统对于图像的码流的每个独立加密段产生来自全局初始化向量的唯一初始化向量,使得即使在截断之后也可以在全局初始化向量的解密期间生成初始化向量。 加密系统使用其唯一的初始化向量来加密每个独立的加密段。 加密系统确保加密的码流符合基于JPEG2000的压缩的语法,原始生成并被加密不知情的设备截断。

    • A system for backend conversion attribution of an advertisement served to a user device. The advertisement server provides an advertisement to the user device. The advertisement server receives user information from the user device. The advertisement server stores attributable event information and the user information into an attributable event record in a data store. Based on a user event, a conversion server receives conversion information and the user information from the user device. The conversion server stores the conversion information and the user information into a conversion record in the data store. An attribution server matches the attributable event record with the conversion record.
    • 用于向用户设备发送的广告的后端转换归属的系统。 广告服务器向用户设备提供广告。 广告服务器从用户设备接收用户信息。 广告服务器将可归因事件信息和用户信息存储在数据存储器中的可归档事件记录中。 基于用户事件,转换服务器从用户设备接收转换信息和用户信息。 转换服务器将转换信息和用户信息存储在数据存储中的转换记录中。 归因服务器将可归因事件记录与转换记录相匹配。

    • A method for service protection is disclosed, which is applied to a 1:n switching technique. The method includes the following steps. A source end sends a service to a work transmission entity, the work transmission entity performs performance monitoring through the transmitted service, a sink end receives the service from the work transmission entity; when a Signal Degrade (SD) fault occurs at the work transmission entity, the source end sends the service to the work transmission entity and a protection transmission entity simultaneously, and the sink end selects to receive the service from the protection transmission entity; the protection transmission entity performs the performance monitoring through the transmitted service; when the SD fault occurs at both the work transmission entity and the protection transmission entity, the sink end still receives the service from the protection transmission entity. A system for service protection is also disclosed. Technical solutions enable the service to get valid protection during the transmission process, and avoid frequent switching of the service, thereby improving the service quality.
