    • A multitasking, graphical windowing operating system for an office machine supporting real time processing, including a method for supporting real time processing in the operating system. The operating system includes a kernel having a non-preemptive scheduler for scheduling windowing applications and a preemptive scheduler for scheduling real time applications. The kernel includes a messaging subsystem for communication among process in the system including both the real time and windowing applications, and further includes an event semaphore maintained by the kernel to manage scheduling. The method includes grouping windowing applications together for scheduling purposes and scheduling windowing applications non-preemptively. The method further includes determining priority of real time applications and scheduling real time applications preemptively with the windowing applications based on priority.
    • 一种用于支持实时处理的办公机器的多任务图形窗口操作系统,包括用于在操作系统中支持实时处理的方法。 操作系统包括具有用于调度加窗应用的非抢占式调度器的内核和用于调度实时应用的抢占式调度器。 内核包括用于在系统中的进程之间进行通信的消息传递子系统,包括实时应用和开窗应用,并且还包括由内核维护以管理调度的事件信号量。 该方法包括将加窗应用程序组合在一起用于调度目的,并且非抢先地调度开窗应用。 该方法进一步包括确定实时应用的优先级,并基于优先级预先与开窗应用程序调度实时应用。

    • The system of the present invention processes data for communication between first and second computers by linearizing the communications message. The message comprises a linear header portion, an extended header portion, and a message body. The linear header portion identifies the number of message recipients and message types. The extended header contains detailed information about the message recipients, such as recipient name and address. The extended header may also contain message subject information, polling information, and password data. The header information is used by the receiving computer to prepare to process the expected data type. The message body may be transferred in a form that takes advantage of the data processing capabilities of the first and second computers. The computers may exchange data processing capabilities so that the most efficient transfer form may be selected. The extended header and message body are encoded using a well-known ASN-1 data encoding process. In addition, the message body may be compressed and encrypted. The system may be readily used in facsimile communication where the first and second computers are facsimile machines.
    • 本发明的系统通过线性化处理通信消息来处理第一和第二计算机之间的通信的数据。 消息包括线性报头部分,扩展报头部分和消息体。 线性标题部分标识消息收件人和消息类型的数量。 扩展头包含有关邮件收件人的详细信息,如收件人姓名和地址。 扩展报头还可以包含消息对象信息,轮询信息和密码数据。 接收计算机使用头信息来准备处理期望的数据类型。 消息体可以以利用第一和第二计算机的数据处理能力的形式传送。 计算机可以交换数据处理能力,以便可以选择最有效的传送形式。 使用公知的ASN-1数据编码处理来对扩展的报头和消息体进行编码。 另外,消息体可以被压缩和加密。 该系统可以容易地用于传真通信,其中第一和第二计算机是传真机。
