Abstract

Abstract A wireless alarm system for generating alarm signals discernible to the hearing impaired. The system includes a detection unit having a smoke or carbon dioxide detector which generates a signal upon sensing the occurrence of smoke or carbon dioxide. A transmitter in the detector unit generates a wirelessly transmitted signal. A receiving unit worn on the body of a person includes a receiver and receives the signal generated by the transmitter. An alarm in the form of a vibrator is coupled with the receiver and generates a vibration discernible to the body of the user. A second alarm operates, or not, depending on whether the person acknowledges the vibrator.

Claims Analysis

Total Claims: 22
Claim 1
Independent Claim 56 words
An alarm system comprising: a detector which generates a signal indicating the presence of fire; and first and second alarms responsive to said signal for stimulating the functioning senses of an individual, the second alarm stimulating the senses of an individual differently than the first, the second alarm having a delayed operation compared to the first.
Claim 2
Dependent Claim 56 words
An alarm system comprising: a detector which generates a signal indicating the presence of fire; and first and second alarms responsive to said signal for stimulating the functioning senses of an individual, the second alarm stimulating the senses of an individual differently than the first, the second alarm having a delayed operation compared to the first.
Claim 3
Dependent Claim 31 words
An alarm system as claimed in claim 1, further comprising a switch by which the first alarm can be acknowledged, operation of the switch for acknowledgement making the second alarm inoperable.
Claim 4
Dependent Claim 25 words
An alarm system as claimed in claim 2, the first alarm comprising a vibrator, the second alarm comprising means for applying electricity to an individual.
Claim 5
Dependent Claim 78 words
An alarm system comprising: a first alarm, a second alarm, an on-off switch operable by an individual between closed and open states, and an electrical mechanism which activates the second alarm after the first alarm, depending on whether the switch is in the closed or open state, the second alarm being electrically connected to the first alarm through a normally open timed closing switch, the second alarm being electrically connected to the first alarm through said on-off switch.
Claim 6
Dependent Claim 78 words
An alarm system comprising: a first alarm, a second alarm, an on-off switch operable by an individual between closed and open states, and an electrical mechanism which activates the second alarm after the first alarm, depending on whether the switch is in the closed or open state, the second alarm being electrically connected to the first alarm through a normally open timed closing switch, the second alarm being electrically connected to the first alarm through said on-off switch.
Claim 7
Dependent Claim 21 words
An alarm system as claimed in claim 4, the on-off switch being in series with the normally open timed closing switch.
Claim 8
Dependent Claim 14 words
An alarm system as claimed in claim 4, the first alarm comprising a vibrator.
Claim 9
Dependent Claim 15 words
An alarm system as claimed in claim 4, the second alarm comprising an electrical stimulator.
Claim 10
Dependent Claim 112 words
A wireless alarm system comprising: detector means for sensing the presence of fire and generating a signal; transmitting means responsive to said signal from said detector means for generating a wirelessly transmitted signal indicative of the presence of fire; receiving means remote from said detector means and said transmitter means for receiving said wirelessly transmitted signal and generating a code electrical signal; first alarm means responsive to said code electrical signal for generating an alarm discernible to the functioning senses of hearing impaired people; and second alarm means delayed with respect to the first alarm means and operable, or not, depending on whether there has been acknowledgement of the first alarm means.
Claim 11
Dependent Claim 112 words
A wireless alarm system comprising: detector means for sensing the presence of fire and generating a signal; transmitting means responsive to said signal from said detector means for generating a wirelessly transmitted signal indicative of the presence of fire; receiving means remote from said detector means and said transmitter means for receiving said wirelessly transmitted signal and generating a code electrical signal; first alarm means responsive to said code electrical signal for generating an alarm discernible to the functioning senses of hearing impaired people; and second alarm means delayed with respect to the first alarm means and operable, or not, depending on whether there has been acknowledgement of the first alarm means.
Claim 12
Dependent Claim 29 words
A wireless alarm system as set forth in claim 8 wherein said detector means senses the occurrence of smoke and generates a signal indicative of the presence of smoke.
Claim 13
Dependent Claim 37 words
A wireless alarm system as set forth in claim 8 wherein said first alarm means is a vibrator responsive to said code electrical signal to create a vibration discernible to the functioning senses of hearing impaired people.
Claim 14
Dependent Claim 36 words
A wireless alarm system as set forth in claim 8 wherein said receiving means and both said alarm means are coupled in a unit constructed and arranged to be worn on the body of a person.
Claim 15
Dependent Claim 35 words
A wireless alarm system as set forth in claim 10 including decoder means coupled with said receiving means for receiving said code electrical signal to generate code signals to said vibrator for pulsing said vibrator.
Claim 16
Independent Claim 102 words
A method of using an alarm system comprising: a detector which generates a signal indicating the occurrence of a predetermined phenomenon; and first and second alarms responsive to said signal for stimulating the functioning senses of an individual, the second alarm stimulating the senses of an individual differently than the first, the second alarm having a delayed operation compared to the first, said method comprising: providing as the detector one which generates a signal indicating the presence of fire; placing the detector at a location to be monitored; and placing the alarms such that they can stimulate the senses of an individual.
Claim 17
Independent Claim 102 words
A method of using an alarm system comprising: a detector which generates a signal indicating the occurrence of a predetermined phenomenon; and first and second alarms responsive to said signal for stimulating the functioning senses of an individual, the second alarm stimulating the senses of an individual differently than the first, the second alarm having a delayed operation compared to the first, said method comprising: providing as the detector one which generates a signal indicating the presence of fire; placing the detector at a location to be monitored; and placing the alarms such that they can stimulate the senses of an individual.
Claim 18
Dependent Claim 34 words
A method as claimed in claim 13, the alarm system further comprising a switch by which an individual can acknowledge the first alarm, operation of the switch for acknowledgement making the second alarm inoperable.
Claim 19
Dependent Claim 24 words
A method as claimed in claim 14, the first alarm comprising a vibrator, the second alarm comprising means for applying electricity to an individual.
Claim 20
Dependent Claim 19 words
A method as claimed in claim 14, said method further comprising placing the alarms and switch on an individual.
Claim 21
Dependent Claim 13 words
A method as claimed in claim 14, the detector comprising a smoke detector.
Claim 22
Dependent Claim 14 words
A method as claimed in claim 14, the detector comprising a carbon dioxide detector.
