Abstract: A Web browser (210) is configured to run in a middle compartment (206) of a Compartmented Mode Workstation (CMW) (200). The operation of the Web browser (210) is prevented from accessing or damaging other compartments of the CMW machine (200) as a result of mandatory access control (MAC), which is configured appropriately. The Web browser (210) communicates with Web servers (252) attached to the internet (240), the Internet being connected to an outside compartment of the CMW machine (210), via a trusted outside process (TPO) (214). TPO (214) has the privileges required to override MAC. The Web browser (210) communicates with a display server (232), which is attached to an inside compartment (204) of the CMW machine (210), via a trusted inside process (TPI) (204). TPI also has privileges to override MAC. The Web browser (210) can request and receive Web pages incorporating mobile code, and can process the mobile code safely within the middle compartment (206). As a result of processing the mobile code, the Web browser (210) sends only X-messages to the display server (232), in order that the display server can render the images resulting from the processed mobile code.

Abstract translation: 网络浏览器（210）被配置为在隔离模式工作站（CMW）（200）的中间隔间（206）中运行。 作为强制访问控制（MAC）的结果，Web浏览器（210）的操作被阻止访问或损坏CMW机器（200）的其他隔离区域。Web浏览器（210）与Web服务器 （252），互联网通过可信外部处理（TPO）连接到CMW机器（210）的外部隔间。 TPO（214）具有覆盖MAC所需的特权。 Web浏览器（210）通过可信赖的内部过程（TPI）（204）与连接到CMW机器（210）的内部隔间（204）的显示服务器（232）进行通信。 TPI也有权重写MAC。 Web浏览器（210）可以请求和接收并入移动代码的网页，并且可以在中间隔间（206）内安全地处理移动代码。 作为处理移动代码的结果，Web浏览器（210）仅向显示服务器（232）发送X消息，以便显示服务器可以渲染由处理的移动代码产生的图像。

Abstract: A patient subjected to laryngectomy is provided surgically with a fistula intended to serve as a pseudo-glottis, and a tracheostome, these two tracts being sited in the midline region of the neck surface. A laryngeal prosthesis for the patient is of generally symmetrical form comprising a hollowed main body with two external tubes to respectively engage the surgically formed tracts, the fistular tube being sufficiently short to avoid inhibiting the psuedo-glottis function. The prosthesis body is apertured to provide a valve function communicating the tracheal tube with atmosphere for respiration, or with the fistular tube for phonation. This function can be effected by a normally open flap valve closable by a first high pressure in the body, and a normally closed blow-out valve may then be appropriate to open at second higher pressure to remove secretions, together with a further normally open valve to close the fistular tube at the higher pressure. Also, a non-return valve is normally appropriate in the fistular tube, and this, or a similar valve, can serve as a tone generator if necessary.

Abstract translation: 经喉切除术的患者通过外科手术提供旨在用作假声门的瘘管，以及气管镜，这两束位于颈部表面的中线区域。 用于患者的喉假体通常是对称形式，包括具有两个外部管的中空主体，以分别接合外科手术形成的束，所述瘘管足够短以避免抑制伪声门功能。 修补体是多孔的，以提供将气管管与呼吸气氛或用于发声的瘘管连通的阀功能。 该功能可以通过在体内通过第一高压关闭的常开的瓣阀来实现，并且常闭的吹出阀可以适于在第二较高压力下打开以除去分泌物，以及另外的常开阀 以更高的压力关闭瘘管。 此外，止回阀通常在瘘管中是适当的，并且如果需要，这个或类似的阀可以用作音调发生器。
