    • A telephone having a non-volatile circuit for automatically dialing 911 upon depression of a single key includes an oscillator activated in response to depression of the key for transmitting clock pulses to a counter. Certain of the output signals from the counter are applied to switches in sequence. The switches are connected to selective column and row leads of the telephone dialer circuit corresponding to the digits in the telephone number to be dialed. The switches short together the respective column and row leads so that the dialer reacts in the same manner it would when the keys of those digits are depressed on the telephone keypad. An output pulse from the counter resets the circuit after the switch connects together the column and row leads of the last digit of the telephone number.
    • 具有用于在按下单个键时自动拨打911的非易失性电路的电话包括响应于按键而激活的振荡器,用于将时钟脉冲发送到计数器。 来自计数器的某些输出信号依次应用于开关。 开关连接到电话拨号电路的选择列和行引线,与要拨打的电话号码中的数字相对应。 这些开关将相应的列和行引线组合在一起,使得拨号器以与在电话键盘上按压这些数字的键时相同的方式进行反应。 在开关将电话号码的最后一位的列和行引线连接在一起之后,来自计数器的输出脉冲复位电路。

    • An apparatus for emergency dialing and oneway communication by telephone includes an autodialing circuit for dialing a preselected emergency telephone number. The circuit is activated by a switch and provides communication of audio information from the vicinity of the device to an emergency services operator during an emergency situation such as a criminal assault of a convenience store. The apparatus is characterized by the presence of a microphone, and the absence of a speaker connection for transmitting the voice of the emergency services operator. In this manner, the criminal assailant is not made aware that police have been contacted.

    • A cellular telephone dialing controller comprising an operator switch, a state machine, digitally stored audio prompts, and a Dual Tone Multi-Frequency signal generator, in which at each dialing step the operator hears sequentially the numerals zero, one, etc. and the operator "dials" by closing the operator's switch when the proper number is played. At completion of "dialing" the entire phone number is audibly replayed for operator approval, after which the call is automatically initiated, including the generation of Dual Tone Multi-Frequency as well as Off-Hook/On-Hook control signals, the entire dialing operation being completed without visual participation or use of the operator's hands, thereby ensuring driving safety.

    • A dialer circuit comprising a microcomputer for controlling the dialing of a telephone. This dialer circuit is capable of storing a telephone number and transmitting a signal concerning this telephone number to a telephone circuit according to a given command. The dialer circuit is equipped with a means for detecting the ON state or the OFF state of a hook switch; upon detection of the state of the hook switch, the dialer circuit performs a resetting of the entire system except a memory in which the telephone number is stored. The result is that when operating the hook switch, it is possible to automatically reset only the system, thus effectively preventing any reckless driving of the system.
