Abstract
Abstract A personal emergency response system (PERS) is disclosed which includes a method and apparatus for monitoring alarm signals to provide improved emergency response capabilities and enhanced system operability. The system includes a local response center for relaying alarm signals received from subscribers to mobile on-site field personnel via individual paging units. The system is also capable of retransmitting an alarm signal in the event that a response to the original alarm signal has not been registered within a predetermined period of time. The system is also provided with redundant communications paths to minimize the possibility of a missed alarm message from a subscriber, and self-test capabilities for detecting system faults and transmitting fault messages to the individual paging units of the system.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
239 words
A monitored personal emergency response system comprising: a response unit operative to receive and decode alarm messages from one or more subscriber units via a first communication link; a computer means operative in response to decoded alarm messages from the response unit to provide corresponding output alarm signals; a paging transmitter operative in response to the output alarm signals from the computer means to transmit predetermined alarm messages to one or more remote paging receiver units operative to denote and display the received predetermined alarm messages; a control unit operative in response to alarm messages received from the one or more subscriber units via the first communication link to provide output signals indicative of received alarm messages; the paging transmitter being operative in response to the output signals from the control unit for transmitting a predetermined paging message to the one or more remote paging receiver units; a calling unit operative in response to the output signals from the control unit indicative of receipt by the control unit of an alarm message from a subscriber unit to direct a supplemental alarm message to a predetermined remote response center; wherein the control unit and the paging transmitter are operative to provide the predetermined alarm message to the one or more remote paging receiver units, even when the response unit or the computer means or both the response unit and the computer means are not operative to provide decoded alarm messages.
Claim 2
Dependent Claim
239 words
A monitored personal emergency response system comprising: a response unit operative to receive and decode alarm messages from one or more subscriber units via a first communication link; a computer means operative in response to decoded alarm messages from the response unit to provide corresponding output alarm signals; a paging transmitter operative in response to the output alarm signals from the computer means to transmit predetermined alarm messages to one or more remote paging receiver units operative to denote and display the received predetermined alarm messages; a control unit operative in response to alarm messages received from the one or more subscriber units via the first communication link to provide output signals indicative of received alarm messages; the paging transmitter being operative in response to the output signals from the control unit for transmitting a predetermined paging message to the one or more remote paging receiver units; a calling unit operative in response to the output signals from the control unit indicative of receipt by the control unit of an alarm message from a subscriber unit to direct a supplemental alarm message to a predetermined remote response center; wherein the control unit and the paging transmitter are operative to provide the predetermined alarm message to the one or more remote paging receiver units, even when the response unit or the computer means or both the response unit and the computer means are not operative to provide decoded alarm messages.
Claim 3
Dependent Claim
51 words
The system of claim 1 wherein the calling unit is operative to direct the supplemental alarm message to a predetermined remote response center when the alarm message received at the control unit from the subcriber unit is received after a predetermined period of time from receipt of a previous alarm message.
Claim 4
Dependent Claim
33 words
The system of claim 1 wherein the computer means is operative at predetermined time intervals to provide test messages to the paging transmitter for transmission of test messages to the paging receiver units.
Claim 5
Dependent Claim
32 words
The system of claim 1 wherein said response unit, computer means, control unit and paging transmitter include: an electrical power source for providing backup power in the event of a power failure.
Claim 6
Dependent Claim
35 words
The system of claim 1 wherein the computer means, upon detection of a decoded alarm message of a predetermined type is set in a reminder mode to provide predetermined reminder messages to the paging transmitter.
Claim 7
Dependent Claim
42 words
The system of claim 5 wherein the computer means is operative in response to a decoded reset signal received from a subscriber unit via the response means to return to an initial condition to await receipt of a subsequent decoded alarm message.
Claim 8
Dependent Claim
69 words
The system of claim 5 wherein the computer means is operative to provide a first reminder message to the paging transmitter for transmission of the first reminder message to a first selected paging receiver unit, and is operative to provide a second reminder message to the paging transmitter for transmission of the second reminder message to the first selected paging receiver and to a second selected paging receiver unit.
Claim 9
Dependent Claim
229 words
A monitored personal emergency response system comprising: a response unit operative to receive and decode alarm messages from one or more subscriber units via a first communication link; a computer means operative in response to decoded alarm messages from the response unit to provide corresponding output alarm signals; a paging transmitter operative in response to the output alarm signals from the computer means to transmit predetermined alarm message to one or more remote paging receiver units operative to denote and display the received predetermined alarm messages; a control unit operative in response to alarm messages received from the one or more subscriber units via the first communication link to provide output signals indicative of received alarm messages; the paging transmitter being operative in response to the output signals from the control unit for transmitting a predetermined paging message to the one or more remote paging receiver units; a calling unit operative in response to the output signals from the control unit indicative of receipt by the control unit of an alarm message from a subscriber unit to direct a supplemental alarm message to a predetermined remote response center; wherein the response unit and the computer means are operative to provide decoded alarm signals to the paging transmitter for transmission to the one more remote paging receiver units even when the control unit is not operative to provide output signals.
Claim 10
Dependent Claim
229 words
A monitored personal emergency response system comprising: a response unit operative to receive and decode alarm messages from one or more subscriber units via a first communication link; a computer means operative in response to decoded alarm messages from the response unit to provide corresponding output alarm signals; a paging transmitter operative in response to the output alarm signals from the computer means to transmit predetermined alarm message to one or more remote paging receiver units operative to denote and display the received predetermined alarm messages; a control unit operative in response to alarm messages received from the one or more subscriber units via the first communication link to provide output signals indicative of received alarm messages; the paging transmitter being operative in response to the output signals from the control unit for transmitting a predetermined paging message to the one or more remote paging receiver units; a calling unit operative in response to the output signals from the control unit indicative of receipt by the control unit of an alarm message from a subscriber unit to direct a supplemental alarm message to a predetermined remote response center; wherein the response unit and the computer means are operative to provide decoded alarm signals to the paging transmitter for transmission to the one more remote paging receiver units even when the control unit is not operative to provide output signals.
