Method and apparatus for waking a person
A system and method for waking a person includes the provision of tactile stimulation in a repeating interrupted pattern upon the detection of an alarm signal indicative of an event for which the person should be awakened. In one embodiment, a device for waking a person comprises a circuit for generating a driver signal in response to an alarm signal, the driver signal having a repeating interrupted pattern; an electrically controlled switching device having a control input, a power input and a power output, the power input being connectable to a power source, the control input being connected to receive the driver signal from the circuit; and a tactile stimulation device connected to the power output of the electrically controlled switching device, the tactile stimulation device being configured to produce a tactile stimulation.

a circuit for generating a driver signal in response to an alarm signal, the driver signal having a repeating interrupted pattern;
an electrically controlled switching device having a control input, a power input and a power output, the power input being connectable to a power source, the control input being connected to receive the driver signal from the circuit; and
a tactile stimulation device connected to the power output of the electrically controlled switching device, the tactile stimulation device being configured to produce a tactile stimulation, whereby a person sensing the tactile stimulation is awakened.
2. The device of claim 1 , wherein the electrically controlled switching device is a transistor.
3. The device of claim 1 , wherein the electrically controlled switching device is a relay.
4. The device of claim 1 , wherein the tactile stimulation device is a bed shaker.
5. The device of claim 1 , wherein the circuit comprises a processor.
6. The device of claim 5 , wherein the processor is a microcontroller.
7. The device of claim 1 , wherein the alarm signal is continuously asserted during an alarm event.
8. The device of claim 1 , wherein each repetition of the interrupted pattern includes an uneven number of “on” and “off” periods of equal duration.
9. The device of claim 1 , wherein each repetition of the interrupted pattern includes a plurality of “on” and “off” periods.
10. The device of claim 9 , wherein at least one “off” period has a duration different from a duration of at least one “on” period.
11. The device of claim 1 , wherein the repeating interrupted pattern comprises a plurality of T3 patterns.
12. The device of claim 1 , further comprising a low frequency annunciator connected to the electrically controlled switching device, the annunciator producing an audible sound below 1500 Hz.
13. The device of claim 1 , further comprising a first light controlled by the driver signal.
14. The device of claim 1 , further comprising a second light connected to the circuit, the circuit further being configured to turn on the second light while the alarm signal is asserted.
15. A method for waking a person, the method comprising the steps of:
detecting an alarm signal, the alarm signal signifying an occurrence of an event to which the person is to be notified; and
providing a tactile stimulation to the person upon detecting the alarm signal, the tactile stimulation having a repeating interrupted pattern, whereby the person is awakened.
16. The method of claim 15 , wherein the tactile stimulation is provided using a bed shaker.
17. The method of claim 15 , wherein each repetition of the interrupted pattern includes an uneven number of “on” and “off” periods of equal duration.
18. The method of claim 15 , wherein each repetition of the interrupted pattern includes a plurality of “on” and “off” periods.
19. The method of claim 18 , wherein at least one “off” period has a duration different from a duration of at least one “on” period.
20. The method of claim 19 , wherein at least one “off” period has a duration different from a duration of at least one other “off” period.
21. The method of claim 19 , wherein at least one “on” period has a duration different from a duration of at least one other “on” period.
22. The method of claim 15 , wherein the repeating interrupted pattern comprises a plurality of T3 patterns.
23. The method of claim 15 , further comprising the step of activating a low frequency audible device in an interrupted pattern upon detection of the alarm signal the low frequency audible device producing a sound at a frequency below 1500 Hz.
24. The method of claim 15 , further comprising the step of turning on a first light during a period of time in which the alarm signal is being asserted.
25. The method of claim 15 , further comprising the step of modifying an intensity of a second light in a repeating interrupted pattern during a period of time in which the alarm signal is being asserted.
