Abstract
Abstract A wake-up alarm is set to ring in some time interval. One or more physical characteristics of the sleeping subject, including brain wave activity, pulse rate, REM activity, muscle tension, body temperature, hearing acuity, positional changes and the like are monitored to determine whether the subject is in a deep or shallow-sleep phase. If the subject is in the deep-sleep phase throughout the alarm time interval, the alarm is inhibited until the end of the alarm interval. The inhibiting of the alarm ends as soon as the subject goes into a shallow-sleep phase.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
186 words
A wake-up alarm comprising, in combination: sensor means associated with a subject and monitoring at least one characteristic of said subject related to the depth of sleep of said subject and delivering an output related to the depth of sleep of said subject; wake-up alarm means; adjustment means connected to said wake-up alarm means to enable said alarm means to sound an alarm at any time within a given time range; inhibit means connected to said wake-up alarm means for inhibiting the operation of said alarm within said given time range when said inhibit means is in a given energization state; signal-processing means connected to said sensor means and producing a first output signal when said sensor's output indicates that said subject is in a deep-sleep or REM state, and producing a second output signal when said sensor output indicates that said subject is in a sleep state shallower than said deep-sleep state; said output signals of said signal-processing means being connected to said inhibit means and causing said inhibit means to inhibit said alarm means when said subject is in said deep-sleep or REM state.
Claim 2
Dependent Claim
186 words
A wake-up alarm comprising, in combination: sensor means associated with a subject and monitoring at least one characteristic of said subject related to the depth of sleep of said subject and delivering an output related to the depth of sleep of said subject; wake-up alarm means; adjustment means connected to said wake-up alarm means to enable said alarm means to sound an alarm at any time within a given time range; inhibit means connected to said wake-up alarm means for inhibiting the operation of said alarm within said given time range when said inhibit means is in a given energization state; signal-processing means connected to said sensor means and producing a first output signal when said sensor's output indicates that said subject is in a deep-sleep or REM state, and producing a second output signal when said sensor output indicates that said subject is in a sleep state shallower than said deep-sleep state; said output signals of said signal-processing means being connected to said inhibit means and causing said inhibit means to inhibit said alarm means when said subject is in said deep-sleep or REM state.
Claim 3
Dependent Claim
48 words
The device of claim 1 which further includes inhibit defeater means for defeating said inhibit means at the end of said given time range, whereby said alarm means produces a wake-up alarm, even though said subject is in a deep-sleep state at the end of said time range.
Claim 4
Dependent Claim
31 words
The device of claim 1 wherein said sensor means monitors brain-wave activity, and wherein said sensor means produces said first output signal when said subject is in a delta sleep phase.
Claim 5
Dependent Claim
48 words
The device of claim 3 which further includes inhibit defeater means for defecting said inhibit means at the end of said given time range, whereby said alarm means produces a wake-up alarm even though said subject is in a deep-sleep state at the end of said time range.
Claim 6
Dependent Claim
31 words
The device of claim 1 wherein said sensor means monitors brain-wave activity, and wherein said sensor means produces said second output signal when said subject is in a beta sleep phase.
Claim 7
Dependent Claim
48 words
The device of claim 5 which further includes inhibit defeater means for defeating said inhibit means at the end of said given time range, whereby said alarm means produces a wake-up alarm even though said subject is in a deep-sleep state at the end of said time range.
Claim 8
Dependent Claim
22 words
The device of claim 1 wherein said sensor means includes devices for monitoring at least two different sleep-related characteristics of said subject.
Claim 9
Dependent Claim
12 words
The device of claim 1 wherein said sensor means monitors pulse rate.
Claim 10
Dependent Claim
11 words
The device of claim 1 wherein said sensor means monitors REM.
Claim 11
Dependent Claim
12 words
The device of claim 1 wherein said sensor means monitors body temperature.
Claim 12
Dependent Claim
12 words
The device of claim 1 wherein said sensor means monitors muscle tonus.
Claim 13
Independent Claim
74 words
The method of waking up a human subject from a sleeping phase; said method comprising the steps of setting a wake-up alarm to start after some given time; measuring at least one sleep-related characteristic of said human subject during at least said given time wherein said characteristic indicates whether said subject is in a deep-sleep, REM or shallow sleep phase; and inhibiting said alarm from starting while said subject is in a deep-sleep phase.
Claim 14
Independent Claim
74 words
The method of waking up a human subject from a sleeping phase; said method comprising the steps of setting a wake-up alarm to start after some given time; measuring at least one sleep-related characteristic of said human subject during at least said given time wherein said characteristic indicates whether said subject is in a deep-sleep, REM or shallow sleep phase; and inhibiting said alarm from starting while said subject is in a deep-sleep phase.
Claim 15
Dependent Claim
32 words
The method of claim 12 which includes the further step of causing said alarm to start after a given time period regardless of the state of said sleep-related characteristic of said subject.
Claim 16
Dependent Claim
12 words
The method of claim 12 wherein said characteristic is brain wave activity.
Claim 17
Dependent Claim
37 words
The method of claim 12 wherein at least two sleep-related characteristics are measured and wherein both of said at least two sleep-related characteristics must indicate that said subject is in said deep-sleep phase to inhibit said alarm.
