    • A two stage virus detection system detects viruses in target files. In the first stage, a training application receives a master virus pattern file recording all known virus patterns and generates a features list containing fundamental virus signatures from the virus patterns, a novelty detection model, a classification model, and a set of segmented virus pattern files. In the second stage, a detection application scans a target file for viruses using the generated outputs from the first stage rather than using the master virus pattern file directly to do traditional pattern matching. The results of the scan can vary in detail depending on a fuzzy scan level. For fuzzy scan level “1,” the existence of a virus is returned. For fuzzy scan level “2,” the grant virus type found is returned. For fuzzy scan level “3,” the exact virus name is returned. This invention provides a solution for the problems caused by traditional virus detection solution: slow scanning speed, big pattern file, big burden on computation resource (CPU, RAM etc.), as well as heavy pattern updating traffic via networks.
    • 两级病毒检测系统检测目标文件中的病毒。 在第一阶段,训练应用程序接收记录所有已知病毒模式的主病毒模式文件,并生成包含病毒模式的基本病毒签名的功能列表,新颖性检测模型,分类模型和一组分段病毒模式文件 。 在第二阶段,检测应用程序使用来自第一阶段的生成输出来扫描目标文件以获取病毒,而不是直接使用主病毒码文件来进行传统的模式匹配。 根据模糊扫描级别,扫描结果可能会有详细的变化。 对于模糊扫描级别“1”,返回病毒的存在。 对于模糊扫描级别“2”,返回发现的授权病毒类型。 对于模糊扫描级别“3”,返回确切的病毒名称。 本发明为传统病毒检测解决方案提供了一个解决方案:扫描速度慢,格式文件大,计算资源负担大(CPU,RAM等),以及通过网络大量更新流量。

    • The present invention provides apparatuses and systems for adjusting a communication channel between a control unit and a remote sensor. A system may include a control unit that controls an environmental unit and a remote sensor that provides data about an environmental factor as measured at the remote sensor. The remote sensor transmits a radio frequency (RF) signal that conveys the data to control unit through a directional antenna. The RF signal is received by the control unit through an omnidirectional antenna, and a signal strength parameter is determined from the received RF signal. A signal strength indication unit provides an indication from the signal strength parameter as a user adjusts the position of the directional antenna. With embodiments of the invention, a signal strength module generates an audio signal in accordance with an audio characteristic, which is indicative of the signal strength of the received RF signal.
    • 本发明提供了用于调整控制单元和远程传感器之间的通信信道的设备和系统。 系统可以包括控制环境单元的控制单元和提供关于在远程传感器处测量的环境因素的数据的远程传感器。 远程传感器通过定向天线传送将数据传送到控制单元的射频(RF)信号。 RF信号由控制单元通过全向天线接收,并且从接收的RF信号确定信号强度参数。 当用户调整定向天线的位置时,信号强度指示单元从信号强度参数提供指示。 利用本发明的实施例,信号强度模块根据音频特性产生音频信号,音频特征指示所接收的RF信号的信号强度。

    • The present invention provides a method of forming a three-dimensional structure of unidirectionally aligned cells. The method comprises providing a substrate with a microchannel. The microchannel is defined by at least a pair of opposing lateral walls and a base. In at least a portion of the microchannel the distance between the pair of opposing lateral walls is within the micrometer range. A first plurality of cells is seeded in the microchannel and the cells are allowed to proliferate up to at least a density of at least 90%. Thereby contact guidance cues are provided by the pair of opposing lateral walls of the microchannel, such that the cells align unidirectionally. Thereby a first layer of aligned cells is also formed at the base of the microchannel. A second plurality of cells is seeded in the microchannel, which already comprises a first layer of aligned cells. When allowing cells of the second plurality of cells to proliferate up to at least substantial confluence, contact guidance cues are again provided by the lateral walls of the microchannel. The cells also align unidirectionally and form a second layer of aligned cells.
    • 本发明提供了形成单向排列单元的三维结构的方法。 该方法包括向基底提供微通道。 微通道由至少一对相对的侧壁和底座限定。 在微通道的至少一部分中,一对相对的侧壁之间的距离在微米范围内。 将第一组多个细胞接种在微通道中,并使细胞增殖至少至少90%的密度。 因此,接触引导线索由微通道的一对相对的侧壁提供,使得单元单向对准。 由此,在微通道的基部也形成第一层对准的单元。 将第二组多个单元接种在微通道中,该微通道已经包括第一层对准的单元。 当允许第二多个细胞的细胞增殖至少至少基本汇合时,接触引导线索再次由微通道的侧壁提供。 单元还单向对准并形成第二层对准的单元。
