    • A method, system and computer program product for preventing at least in part a hacker from performing unwanted activities such as in a file system. A security layer may be added in the kernel space configured to determine whether a request to provide a service from a particular user was received from user space or kernel space. If the request was received from user space, then the user is an unauthenticated user. That is, the user may be a potential hacker. Subsequently, the security layer may determine whether the request satisfies requirements for unauthenticated requests. If the request was received from a secure connection manager in kernel space then the user may be treated as an authenticated user. The secure connection manager may be configured to establish a secure authorized connection with an authenticated user. Subsequently, the security layer may determine whether the request satisfies requirements for authenticated requests.
    • 一种方法,系统和计算机程序产品,用于至少部分地防止黑客执行诸如文件系统中的不必要的活动。 可以在内核空间中添加安全层,以配置为确定是否从用户空间或内核空间接收到从特定用户提供服务的请求。 如果从用户空间接收到请求,则该用户是未经身份验证的用户。 也就是说,用户可能是潜在的黑客。 随后,安全层可以确定请求是否满足未认证请求的要求。 如果在内核空间中从安全连接管理器接收到请求,则用户可被视为经过身份验证的用户。 安全连接管理器可以被配置成与经认证的用户建立安全的授权连接。 随后,安全层可以确定请求是否满足认证请求的要求。

    • The present invention relates to a system and method suitable for automatic cleaning of a coating or extrusion head of a coating apparatus. The invention includes a scrubbing station wherein a combination of physical contact and strong solvent solution combine to remove coating fluid from the exterior of an extrusion head. A second cleaning station, preferably a rinsing station then further cleans the head of coating fluid and removes solvent used at a first cleaning station. The solvent used at the rinsing station is preferably self-drying thereby obviating the need for any further cleaning action. The invention also provides for the ability to prime the coating bead at the extrusion head so as to have a fully formed bead ready before the head begins coating a substrate, thereby providing an even coating across said substrate. The priming operation preferably comprises holding the head steady over a rotating priming roller while extruding fluid preferably at a constant volumetric flow rate. The extrusion head is removed from the priming station when the coating bead is properly formed, and the extruded coating material is dissolved in a solvent bath at the priming station. The priming operation may also be performed at either of the cleaning stations.
    • 本发明涉及一种适用于自动清洁涂布装置的涂布或挤压头的系统和方法。 本发明包括洗涤站,其中物理接触和强溶剂溶液的组合组合以从挤出头的外部除去涂布液。 第二清洁站,优选漂洗站,然后进一步清洁涂布液的头部并除去在第一清洁站使用的溶剂。 在漂洗站使用的溶剂优选是自干燥的,从而避免需要进一步的清洁作用。 本发明还提供了在挤出头处填充涂布珠的能力,以便在头开始涂覆基底之前具有准备好的完全成形的珠,从而在所述基底上提供均匀的涂层。 起动操作优选地包括将头部稳定地保持在旋转启动辊上,同时优选以恒定的体积流速挤出流体。 当涂覆珠被适当地形成时,挤出头从灌注站移除,并且将挤出的涂覆材料溶解在起动站的溶剂浴中。 启动操作也可以在任一个清洁站进行。
