Abstract
Abstract A telephone care system enables personnel monitoring an emergency response center to be reminded that help is still needed at a given location. The system includes a provision for sending a plurality of alarm messages, wherein one criterion for selection of the message being sent is whether a message was previously sent without the alarm state thereafter having been terminated. In a preferred embodiment, a communication system in accordance with the invention includes a provision for sending repetitively, after an initial alarm message, a message to the effect that "help is still needed" until the alarm state has been terminated.

Claim 1
Independent Claim
192 words
A system for communication by telephone wires of information concerning the circumstances of a subscriber, the system comprising: (a) line-seizing means for connecting a communicator output to the telephone wires; (b) dialing means for dialing a telephone number over the communicator output; (c) alarm means, for, in the event of a specified occurrence, entering an alarm state; (d) message selection means, for selecting a message from a plurality of predetermined messages, at least one criterion for selection being whether a message was previously sent without the alarm state of the alarm means thereafter having been terminated, so that a first message is selected when the system first enters an alarm state, and a second, supplementary message is selected at a specified time interval thereafter during a continuing alarm state; and (e) control means, activated by the alarm means and further connected to the line-seizing means, the dialing means, and the message selection means, for (i) activating the line-seizing means and the dialing means, (ii) sending a message selected by the message selection means, and (iii) causing the alarm state of the alarm means to be terminated on receipt of a reset signal.
Claim 2
Independent Claim
192 words
A system for communication by telephone wires of information concerning the circumstances of a subscriber, the system comprising: (a) line-seizing means for connecting a communicator output to the telephone wires; (b) dialing means for dialing a telephone number over the communicator output; (c) alarm means, for, in the event of a specified occurrence, entering an alarm state; (d) message selection means, for selecting a message from a plurality of predetermined messages, at least one criterion for selection being whether a message was previously sent without the alarm state of the alarm means thereafter having been terminated, so that a first message is selected when the system first enters an alarm state, and a second, supplementary message is selected at a specified time interval thereafter during a continuing alarm state; and (e) control means, activated by the alarm means and further connected to the line-seizing means, the dialing means, and the message selection means, for (i) activating the line-seizing means and the dialing means, (ii) sending a message selected by the message selection means, and (iii) causing the alarm state of the alarm means to be terminated on receipt of a reset signal.
