    • A low-noise amplifier circuit is specified which has a switchable gain ratio. For this purpose, a parallel circuit comprising a first and a second current path (3, 4) is provided between a radio-frequency signal input and output (1, 2), with the first current path (3) having a transistor which is connected in a common-base circuit for signal amplification, and the second current path (4) having a transistor which is connected in a common-emitter circuit (7) for signal amplification, and has input impedance matching (25, 27). Owing to the good noise characteristics and the good linearity characteristics, the described low-noise amplifier circuit is suitable for use in radio-frequency receivers in which adaptive pre-amplification is required even before a frequency converter, that is to say at the radio-frequency level, because the input signal has a wide dynamic range, such as that in the case of UMTS.

    • A Fiber Channel circuit (150) has a Fiber Channel switch (152) that receives data frames on input ports (142) and writes the frames to a data storage device (158) from an output port (156) A port server (162) backs up the frames to a data storage backup device (160) by reading data volumes from the data storage device (158) and writing backup copies of at least some of the read data volumes to the data storage backup device (160) A data monitor (166) receives the frame data from the output port and applies it to the data storage device (158) The data monitor (166) also applies it to the port server (162) The port server (162) identifies frames in the volume that have been changed during the backup process. The identified frames are either reread from the data storage array (158), or from a memory (168) associated with the port server (162), and written to the data storage backup device (160).

    • This invention relates to the veracity of information displayed to a user of a computer, and information provided to a computer by human input devices such as mice and keyboards. A digital video guard (DVG) device is a peripheral that is retrofitted to commodity computer devices. The DVG resides in-line with a digital display and enables secure end-to-end interactions between a user and a displayed (usually remote) application. In-band signalling within the digital video stream is used to carry encrypted information from a local or remote source, over untrusted network infrastructure through the digital video guard device to a user. The DVG decrypts and verifies the integrity of the digital video. The integrity of the displayed information is indicated by a trusted LED on the DVG hardware. Portions of the video signal may be designated as trusted, if the received data has been encrypted, signed, or labelled as trustworthy.
    • 本发明涉及显示给计算机的用户的信息的真实性,以及由诸如鼠标和键盘的人类输入设备提供给计算机的信息。 数字视频保护(DVG)设备是被改装为商用计算机设备的外设。 DVG与数字显示器保持一致,并实现用户与显示(通常是远程)应用程序之间的安全的端到端交互。 数字视频流内的带内信令用于通过数字视频保护装置向用户携带来自本地或远程源的不可信网络基础设施的加密信息。 DVG解密并验证数字视频的完整性。 显示信息的完整性由DVG硬件上的可信指示灯指示。 如果接收到的数据已被加密,签名或标记为可靠,则视频信号的部分可被指定为可信任的。
