摘要： A system is described for assisting the hard of hearing in the use of the telephone, in which an in-line text display is inserted in the telephone line before a standard telephone. The in-line display blocks text related digital communications signals to the standard telephone and decodes the text related digital signals to display on a built in display screen.

摘要： A telecommunication device for the deaf includes a self-identification sequence which automatically commences upon the initiation of communication with the device. The self-identification sequence consists of a series of characters which may be separated by pauses and the device listens during the pauses to see if TDD communication has been established. The purpose of the character string is so that a receiving station can identify, with a low rate of error, a calling TDD and therefore switch the incoming call to a TDD equipped operator. This capability is particularly useful for emergency service operators (911 services) which must be able to handle incoming TDD calls with a maximum of efficiency and a minimum of error.

摘要： A unified TDD and telephone incorporate intelligent mode switching to permit users of either device to use the integrated unit with the other features remaining largely invisible by sensing various signals including the removal of the handset or the turning on and off of the TDD device to determine the likely mode of a transmission and the detection of text to determining the likely mode of the receive text. This intelligent mode conversion includes a voice carryover mode in which text and voice may both be transmitted.

摘要： A telecommunication device for the deaf is designed to operate under an enhanced TDD communication protocol. The TDD is capable of communicating with conventional TDDs operating under normal Baudot/Weitbrecht communications, but is also capable of communicating with a similarly enhanced TDD utilizing an enhanced protocol with a faster data transfer rate. The enhanced TDD is capable of signaling to another remote TDD through the use of a synchronization character that it is capable of enhanced TDD communications. If a similar synchronization character is received from the remote station, both TDDs can then switch to enhanced TDD communication with its advantages of speed and enlarged character set. The enhanced protocol permits increased functionality of the TTD terminals in providing machine-to-machine communication in a manner invisible to the TTD user. A machine-to-machine control character similar to the synchronizing character is used to designate such messages.

摘要： A telecommunication device for the deaf operates under conventional Baudot communication protocol, but has enhanced features enabling it to handle interrupts either from a conventional or a similar TDD. The improved TDD is also capable of pseudo-duplex communication with a similar TDD in which each device transmits packets of characters alternatively to the other thus making it appear to the users that simultaneous transmission is occurring. The implementation of these features is done in such a way that the TDD is fully capable of communication with existing TDD devices and the device obeys normals rules and conventions for Baudot communication.
摘要翻译：用于聋哑的电信设备在常规的Baudot通信协议下操作，但是具有增强的特征，使得其能够处理来自常规或类似TDD的中断。改进的TDD还能够与类似的TDD进行伪双工通信，其中每个设备将字符分组发送给另一个字符，从而使用户看起来同时发送。这些功能的实现以这样的方式完成，即TDD完全能够与现有的TDD设备通信，并且设备遵循Baudot通信的法线规则和约定。

摘要： A pipeline-cleaning travelling ''''pig'''' ball having a generally spherical main body formed of a resiliently deformable material. The main body of the ball is provided with plurality of discrete, discontinuous, spaced-apart protuberances upstanding from the surface thereof; the protuberances being of a hardness greater than that of the main body. Preferably, the protuberances are spaced substantially uniformly over the spherical surface of the main body. The invention also contemplates the provision of a pipeline-cleaning kit comprising a first lead ''''pig'''' ball and a second follower pig ball; the second or follower pig ball having a main body formed of a resiliently deformable material having a hardness greater than the hardness of the main body of the first or leading pig ball.
