    • The present invention provides a portable dental system for use in areas having inadequate sources of power, either for human or for veterinary dentistry. The system provides one or more handpieces, each driven driven by a pressurized nitrogen gas contained in a portable tank. A water reservoir is also provided for medicated water to be applied to the tooth site. The system has two channels to which either a conventional dental handpiece or an abrasive handpiece can be attached. When two abrasive handpieces are attached, two different abrasive materials may be used by the system, one material for cleaning and one material for cutting or abrading.
    • 本发明提供一种便携式牙科系统,用于在人或兽医学上具有不足的动力源的区域。 该系统提供一个或多个手持件,每个手持件由容纳在便携式罐中的加压氮气驱动。 还提供了一个用于向牙齿部位施用的药水的储水器。 该系统具有两个通道,传统的牙科手柄或研磨手柄可以连接到该通道。 当安装两个研磨手柄时,系统可以使用两种不同的研磨材料,一种用于清洁的材料和一种用于切割或研磨的材料。

    • Apparatus and method for polymerizing cement under pressurized conditions and for applying the cement under pressure at the appropriate time to a human bone cavity for implantation of a prosthesis, including a stemmed femoral component and an acetabular component. This apparatus alters the physical conditions under which bone cement cures, causing a decrease in cement porosity and thus increasing the resultant cement strength. The apparatus includes a pneumatically actuated gun having a piston for applying pressure to the cement, and applying cement to the bone, a pressurizable housing securable to the gun for containing the cement, and a nozzle having a valve which allows the cement to remain pressurized until application thereof through the nozzle. In one embodiment, one component of a two component polymerizable cement is provided in a sealed bladder secured to the nozzle while the other component is injected into the bladder and mixed with the first component when the cement is ready for use. A vent may be provided in the piston of the pneumatic gun to allow air to escape through the piston to prevent the injection of air into the cement. A sealing gasket may be provided on the end of the nozzle for placement over the open end of the bone cavity so that cement can be applied thereto under pressure.
    • 用于在加压条件下聚合水泥的装置和方法,并且用于在合适的时间在压力下将水泥施加到人骨腔,用于植入假体,包括茎状股骨部件和髋臼部件。 该装置改变骨水泥固化的物理条件,导致水泥孔隙度降低,从而增加所得到的水泥强度。 该设备包括气动致动的枪,其具有用于向水泥施加压力并将骨水泥施加到活塞上的活塞,用于容纳水泥的可固定到枪的可加压壳体,以及具有允许水泥保持加压的阀的喷嘴,直到 通过喷嘴的应用。 在一个实施方案中,双组分可聚合水泥的一个组分设置在固定到喷嘴上的密封囊中,而当水泥准备使用时,将另一组分注入到气囊中并与第一组分混合。 可以在气动枪的活塞中设置排气口,以允许空气通过活塞逸出,以防止空气注入水泥中。 可以在喷嘴的端部设置密封垫圈以放置在骨腔的开口端上,使得水泥可以在压力下施加到其上。

    • A host based security system for a computer network includes in communication with the network a credential host that is operative in concert with a local computer and a destination site. The destination site has a credential authentication policy under which credentials associated with the local computer upon being authenticated authorizes data to be communicated between each of the destination site and the local computer during a communication session over the network. The credential host stores the credentials to be used by the destination and is operative to transmit the credentials onto the network in response to a request received from the local computer. The destination site upon the credentials being received and authenticated thereat is operative to transmit session information onto the network. In turn, the local computer is then operative to commence the communication session upon receipt of said the information.
    • 用于计算机网络的基于主机的安全系统包括与网络通信与本地计算机和目的地站点协同工作的凭证主机。 目的地站点具有凭证认证策略,在该认证策略下,通过认证授权与本地计算机相关联的凭证授权在通过网络的通信会话期间在每个目的地站点和本地计算机之间传送数据。 凭证主机存储目的地使用的证书,并且可操作地响应于从本地计算机接收到的请求将凭证发送到网络上。 在正在接收和认证的证书上的目的地站点可操作以将会话信息发送到网络上。 反过来,本地计算机然后在接收到所述信息后开始通信会话。
