    • The invention relates to techniques for controlling a dynamic hitless resizing in data transport networks. According to a method aspect of the invention, a network connection comprises M tributary slots defined in a payload area of a higher order transport scheme of the data transport network and the method comprises the steps of receiving a connection resize control signal at each of the nodes along the path of the network connection; adding at each node along the path in response to the connection resize control signal a second set of N tributary slots to the first set of the M tributary slots, such that the network connection comprises M+N tributary slots; and increasing, after M+N tributary slots are available for the network connection at each node along the path, a transport data rate of the network connection.

    • 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.

    • 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。
