摘要： The telephone system of the present invention is realized by a unique dynamic time slice architecture which allows for up to 480 transfers of data. A dual port RAM is utilized in which are stored two pages of data, containing time slice information identifying the sending and receiving devices for each time slice slot within the frame. The time slice configuration can be easily modified to accommodate a change in the current system configuration, for example, a handset connecting or disconnecting from a central office line, or the initiation of a conference call. The time slice configuration is modified by updating the second page and swapping the two pages at the beginning of the next frame so that the time slice controller accesses the second page and the configurations specified therein. Thus the system can be updated and controlled in real time with no delays to the users of the telephone system. The telephone system of the present invention further provides a dynamic conferencing capability which can accommodate a large number of users with no additional circuitry and little additional system overhead. The conferencing circuit linearly combines digitized audio data received from different sources over successive time slice slots in a single frame on a real time basis wherein parties can be added or removed simply by adding or removing the connections to the time slice slots.
摘要翻译：本发明的电话系统通过独特的动态时间片结构来实现，其允许多达480个数据传输。使用双端口RAM，其中存储两页数据，其中包含标识帧内每个时间片时隙的发送和接收设备的时间片信息。可以容易地修改时间片配置以适应当前系统配置的变化，例如，连接或断开与中心局线路的手机或者召开电话会议。通过更新第二页并在下一帧的开头交换两个页面来修改时间片配置，使得时间片控制器访问第二页以及其中指定的配置。因此，可以实时更新和控制系统，而不会延迟电话系统的用户。本发明的电话系统还提供动态会议能力，其可以容纳大量用户，没有额外的电路和少量额外的系统开销。会议电路在实时基础上将单个帧中连续时间片时隙上的从不同来源接收的数字化音频数据线性组合，其中可以通过添加或去除与时间片时隙的连接来简单地添加或删除各方。

摘要： Disclosed is a device which can utilize, as an input signal, the solution to mathematical problems from an analog computer or which can be used directly with a process that is governed by a mathematical problem to pictorially depict the solution to the problem. The problem being solved can be dynamically displayed on a device such as a conventional television receiver for use by a student, technician or the like. The input signal indicative of the solution of the mathematical problem is fed to a memory and control device which can store the same for subsequent use. The memory also has stored therein data representative of the images necessary to create the pictorial representation of the problem. A programmable device, preferably in the form of a digital computer, interprets the input signals and directs the data in the memory so that it is properly displayed on the television receiver.

摘要： A transaction execution system includes a host data processing system having a multiple account data base and a plurality of transaction terminals in communication with the host. The terminals each include a keyboard, a display, document handling subsystems, a hardware control subsystem, a communication subsystem and a programmable control subsystem supervising the other subsystems. A user initiates a transaction request by inserting a card into one of the terminals. After reading acceptable account identification information from the card the terminal requests entry of a preassigned personal ID number through the keyboard. The ID number is encrypted by the terminal at least once and communicated to the host along with information read from the card and entered via the keyboard. The host accesses from its stored data base an encrypted ID number corresponding to the received card information and makes a verification comparison of the stored encrypted ID number with the encrypted ID number received from the terminal. By requiring the entry of a nonencrypted ID number at a terminal while storing only encrypted ID numbers at the host, the correspondence between credit card account information and ID numbers need be known only to a few key personnel having access to both the encryption algorithm and a particular key therefor.
