Abstract

An automatic telephonic message transmission apparatus is disclosed which includes a base station and preferably a remote unit for receiving inputs indicative of various operator emergency conditions and for thereupon automatically sequentially dialing a plurality of preselected telephone numbers, and for thereupon transmitting aural messages indicative of the alarm condition. The apparatus includes solid state memories for storing a digital representation of aural messages, keyboard for inputting information such as selected telephone numbers, alarm times, etc., and a controller for acting on the input signals and keyboard entered data for controlling the automatic dialing operations.

Claims

1. Apparatus for automatically transmitting over a telephone line aural messages humanly intelligible as spoken words and indicative of a user emergency, comprising a base station including

(i) solid-state message storage means having digitally preencoded therein at least one aural message;

(ii) converter means for providing an analog signal capable of generating an aural presentation of said message;

(iii) keyboard means for inputting digital data representing at least one telephone number;

(iv) signal processing means including

(a) solid-state digital data storage means;

(b) a clock means for providing an alarm-time-signal at a selected alarm time;

(c) means for generating a user-disabled-signal a given length of time after the occurrence of said alarm-time-signal;

(d) control means responsive to said user-disabled-signal for activating said data storage means to provide on an output terminal a signal train capable of initiating automatic dialing of at least one telephone number and for activating said message storage means to transmit on said output terminal said analog signal;

(v) switch means activatable by a user for preventing the generation of said user-disabled-signal; and

(vi) an alphanumeric display coupled to said keyboard means and to said signal processing means for enabling verification of keyboard entered data.

2. An apparatus according to claim 1, further comprising means for inputting a user identification-code into said data storage means, and means for activating said data storage means after a predetermined time delay to supplement said aural message with said user-identification-code in humanly intelligible form.

3. An apparatus according to claim 1, further comprising means for inputting to said clock means and to said display signals indicative of an on-going time setting and at least one selected alarm time setting.

4. An apparatus according to claim 1, further comprising means for receiving input signals indicative of at least one additional alarm condition, and means responsive to said additional alarm condition signals for supplementing said aural message with information indicating the type of additional alarm is humanly intelligible form.

5. An apparatus according to claim 1, further comprising means for filtering said analog signal to eliminate high frequency components such as may be generated in the process of transforming said digitally preencoded messages into said analog signal, thus improving the intelligibility thereof.

6. An apparatus according to claim 1, further comprising means for disabling said keyboard means to prevent unauthorized entry of input signals.

7. An apparatus according to claim 1, wherein said base station further comprises receiver means for receiving a radio signal indicative of an operator-emergency and for generating an operator-emergency-alarm-signal in response thereto, and means responsive to said operator-emergency-alarm signal for supplementing said aural message with information indicating an operator emergency, and wherein said apparatus further comprises a remote unit including switch means actuatable by a human operator, means operatively coupled to said switch means for generating an emergency signal in response to said actuation, and transmitter means for transmitting said radio signal in response to said emergency signal.

8. An apparatus according to claim 7, wherein said transmitter means includes means for transmitting a selected code identifying a given remote unit and wherein said base station means includes means responsive to selected transmitter codes entered into said keyboard means for recognizing a selected code in a received radio signal and for providing a unique operator emergency signal matched to a selected code.

9. An apparatus according to claim 1, including means responsive to two levels of inputs on said keyboard, one level requiring the prior input of a special programmed code for enabling response to further inputs on said keyboard, so as to avoid confusion between the infrequent entry of relatively constant information which must be preceded by said special programmed code, and the entry of information likely to be frequently changed.
