Definitions
- Waking persons from sleep is of significant importance because the majority of fire deaths in residential settings occur between the sleeping hours of 11 :00 pm and 6:00 am. Although only 20% of fires are reported to have taken place during this temporal window, nearly 50% of fire fatalities occur during this time [Ahrens, 2003].
- U.S. Patent No. 5,651,070 describes a warning device that "listens" for sounds made by devices such as doorbells and smoke detectors and activates a tactile stimulation device in the form of a wrist-watch. This device records a desired audio alarm and continually compares the recorded alarm to ambient sounds picked up from a microphone. This device is burdensome to use in that it requires the user to record the desired sound prior to use. This can be a problem, for example, when a person enters a hotel room late at night because activation of the smoke detector alarm for the purpose of making the recording may disturb other guests.
- the standard audible smoke detector the emergency alerting system recommended by the fire community, was proven to be effective in awakening 58% of the hard of hearing population and 0% of the deaf subjects.
- the weighted average effectiveness per hearing level for the U.S. population was found to be 84%.
- the visual alerting device which is the recommendation by the fire safety community for the hearing impaired population was found to be effective only 35% of the time for the hearing impaired and 60% for the deaf subjects.
- the visual alerting device had an effective awakening of less than 35% for the hearing able population and a weighted average effectiveness across all hearing levels of 35%.
- a low frequency audible horn 400-500 Hz and approximately 85 dB, was tested with thirty-six persons of varying hearing ability. Of the five subjects with no hearing loss, all were awakened by the low frequency audible horn. Of the partially hearing subjects, 92% were awakening by the low frequency horn, 35% more frequently than with the standard audible horn. Of the fully deaf subjects, 11% awoke to the low frequency horn. The low frequency horn effectively awakened a larger percentage of subjects, regardless of hearing ability, than the standard audible horn.
- a system including a tactile stimulation device that provides non-constant tactile stimulation in order to awaken a person.
- the tactile stimulation provided by the tactile stimulation device follows the same temporal pattern as the audible alarm in smoke/fire detectors manufactured after 1996, which is set forth in National Fire Protection Association standard NFPA 72.
- the tactile stimulation device is a bed shaker in preferred embodiments.
- the tactile stimulation device may be used to wake a person for any reason.
- the tactile stimulation device may be connected to a smoke/fire detector or a carbon monoxide detector.
- the tactile stimulation device is connected to a device described in the above-referenced commonly owned co-pending U.S. patent application that detects an audible alarm from a smoke detector.
- the tactile stimulation device may be connected to an alarm clock to wake a person at a desired time.
- the tactile stimulation device may be connected to a door bell or a telephone.
- the tactile device may be coupled with a light (preferably an LED) which decreases and increases in intensity with the same T-3 pattern as the vibratory portion of the device. Although the light dims during periods corresponding to the "off portions of the T3 pattern, the light maintains sufficient light intensity to allow for the recognition of an egress path from the room in which the device was placed.
- a light preferably an LED
- two lights are provided. The first light activates in a T-3 pattern at the time at which the tactile device is active, and the second light maintains a steady intensity to aid in the egress process.
- the tactile device may also be coupled with a device that produces a low frequency sound.
- the low frequency sound has been shown to effectively waken those with hearing loss in the higher frequencies.
- the low frequency sound preferably has a frequency below 1500Hz, more preferably in the range of 300Hz-600Hz, and most preferably in the range of approximately 400-500 Hz and replicates the T-3 pattern of the tactile device.
- Figure 1 is a timing diagram showing the audible alarm pattern for smoke detectors set forth in National Fire Protection Association standard NFPA 72.
- Figure 2 is a block diagram of a system for waking a person according to one embodiment of the present invention.
- Figure 3 is a circuit diagram of a portion of the tactile stimulation device of Figure 2.
- Figure 4 is a block diagram of a system for waking a person according to another embodiment of the invention.
- Figure 5 is a flowchart showing the operation of a microcontroller that forms part of the system of Figure 4.
- Figure 6 is a perspective view showing an exemplary housing for a portion of the circuit of the system of Figure 4.
- Figure 7 is a perspective view showing an exemplary housing for a bed shaker according to an embodiment of the invention.
- a constantly vibrating tactile stimulation device is less than optimal for waking persons, particularly hearing impaired or deaf persons, from sleep.
- NFPA 72 mandates that smoke detectors emit audible alarm signals with a repeating temporal pattern shown in Figure 1 ( Figure 1 illustrates two repetitions of the repeating temporal pattern).
- This pattern also referred to herein as a T- 3 pattern, may be described as consisting of three short "on” periods, each of which is separated by a short "off period, followed by a longer "off period.
- the length of the short on and off periods is specified as 0.5 seconds "on” +/- 10% followed by 0.5 seconds "off +/- 10%.
- the long "off period is specified as 1.5 seconds +/- 10%.
- the above- described T3 pattern may be described as consisting of an uneven number of "on” and “off periods of equal half-second (+/- 10%) duration; i.e., a first "on” period, a first "off period, a second "on” period, a second "off period, a third “on” period, and three consecutive "off periods..
- FIG. 2 A block diagram of the T-3 pattern bed shaker system is illustrated in Figure 2.
- An alarm signal from a smoke detector (not shown in Figure 2) or other device is input to a T-3 circuit 110.
- the T-3 circuit When the alarm signal is present, the T-3 circuit outputs a signal matching the T- 3 temporal pattern illustrated in Figure 1.
- This output signal from the T3 circuit controls a power field effect transistor (FET) 120 (or other switching device, such as a relay) such that power is applied to a bed shaker 130 when the output signal from the T-3 circuit 1 10 is "high.” In this manner, the bed shaker 130 vibrates when the T-3 temporal pattern is "high” and does not vibrate when the T-3 temporal pattern is low.
- FET power field effect transistor
- FIG. 3 A detailed circuit diagram of a preferred embodiment of the system of Figure 2 is illustrated in Figure 3.
- a bed shaker 230 is connected between the positive terminal of a power supply 240 and the drain of a power FET 220.
- the source of the power FET 220 is connected to the negative terminal of the power supply 240.
- a circuit is formed through the power FET 220 such that power is supplied to the bed shaker 230 when a sufficiently positive signal is applied to the gate of the power FET 220.
- the gate of the power FET 220 is controlled by the "brass" output (pin 10) of a Motorola/Freescale MC 145018 ionization smoke detector integrated circuit, which is typically used to drive a horn.
- This MC145018 IC 21 1 is described in data sheet MC145018/D (available at www.freescale.com/files/sensors/doc/data_sheetMC145018.pdf), the contents of which are hereby incorporated by reference herein.
- the horn driver output signal on pin 10 is a high frequency square wave during the "on” portions of the T-3 pattern.
- the output signal on pin 10 is held to a constant "on” state during the "on” portions of the T3 pattern.
- an activation input 250 from a smoke detector or other device is connected to pin 2, which is the "I/O" pin of the MC145018 IC 211.
- This pin is normally used to interconnect several units so that a smoke detection in one unit will trigger an alarm in all units.
- the MC145018 IC 21 1 itself for the smoke detection function.
- the remaining connections to the MC 145018 IC 21 1 shown in Figure 3 are straightforward. Power to the IC is supplied at pin 6 from power source 260, and the IC 21 1 is grounded at pin 9.
- a timing resistor R2 (8.2 M ⁇ recommended) and a timing capacitor Cl (0.1 ⁇ F recommended) are connected to pin 7.
- pin 12 is connected to a capacitor C2 (also 0.1 ⁇ F recommended).
- the activation input signal 250 is preferably generated by a smoke/fire detector.
- the invention is not so limited and the other devices such as carbon monoxide detectors, alarm clocks, doorbells, telephones, etc., may also be used as the source of the activation input signal 250.
- the invention may also be used with the device disclosed in the above-referenced commonly owned U.S. patent application, which detects the audible alarm from a smoke detector.
- a block diagram of another embodiment 400 is illustrated in Figure 4.
- This embodiment is controlled by a microcontroller 410.
- the microcontroller 410 receives an alarm signal input from a device such as a smoke detector, a circuit for detecting an audible alarm from a smoke/fire detector such as that disclosed in the above-referenced commonly owned U.S. patent application, a doorbell, a telephone, or any other device (not shown in Figure 4).
- the alarm signal is preferably continuously asserted while the alarm condition exists.
- the alarm signal is continuously asserted while smoke or fire is detected rather than only being asserted when an audible alarm signal is generated.
- the alarm signal is continuously asserted while the phone is ringing, including the periods between the rings.
- the alarm signal is continuously asserted while the doorbell is ringing.
- the microcontroller 410 is connected to control a relay 420, which is connected between a power source 430 and a tactile stimulation device 440. This allows microcontroller 410 to turn the tactile stimulation device 440 on and off. Electrically controlled switching devices (e.g., transistors) other than the relay 420 may be used in other embodiments.
- a first light emitting diode (“LED") 450 and a second light emitting diode 460 are also connected to the microcontroller 410.
- the first LED 450 is constantly lit while the alarm signal is asserted in order to provide light for egress from a room or to assist a user in taking other action (e.g., answering a telephone, locating a light switch, etc.).
- the second LED 460 is strobed (either on and off or from a bright condition to a dim condition) while the alarm signal is asserted.
- the second LED 460 is strobed in the same T3 pattern in which the tactile stimulation device 440 is activated.
- a low frequency audible horn 470 preferably approximately 500 Hz, is also connected to the microcontroller 410.
- the low frequency horn 470 is also preferably activated in the same T3 pattern in which the tactile stimulation device 440 is activated.
- the microcontroller 410 determines whether an alarm signal is detected at step 510. If no alarm signal is present, the microcontroller repeats step 510 until an alarm signal is detected. When an alarm signal is detected, the microcontroller 410 turns the first LED 450 on at step 520. Next, the microcontroller 410 activates the second LED 460, the low frequency horn 470, and the tactile stimulation device 440 (by controlling the relay 420) in a non-continuous, or interrupted, pattern at step 530. Preferably, the interrupted pattern is the T3 pattern discussed herein. The microcontroller 410 then determines whether the alarm signal is still being asserted at step 540.
- the microcontroller 410 If the alarm signal is being asserted, the microcontroller 410 jumps to step 530 to continue activation of the second LED 460, the low frequency horn 470, and tactile stimulation device 440 in the non-continuous pattern. If the alarm signal is no longer being asserted, the microcontroller 410 turns the first LED 450 off at step 550 and jumps to step 510.
- the second LED 460 and the tactile stimulation device 440 are always activated for at least one complete period of the non-continuous pattern even if the alarm signal terminates prior to the completion of the non-continuous pattern period.
- the microcontroller 410 may be programmed to terminate the activation of the second LED 460 and the tactile stimulation device 440 as soon as the alarm signal is no longer asserted.
- the microcontroller 410 may be programmed to activate the first and second LEDs 450, 460, the horn 470 and the tactile stimulation device 440 for a predetermined period of time or until a user deactivates the device.
- an alternative to the two-LED embodiment illustrated in Figures 4 and 5 is an embodiment with a single LED.
- the single LED is made bright when the tactile stimulation device is active and made dim (but still bright enough to provide light in order to facilitate egress from the room or other action) when the tactile stimulation device is inactive (e.g., during the "off periods of the T3 or other non-continuous pattern).
- FIGs 6 and 7 are perspective views of housings 600, 770 in which the embodiment described in Figure 4 may be enclosed.
- the housing 600 is preferably sized to be placed on a tabletop 610 such as a nightstand.
- the microcontroller 410, relay 420, power source 430 and low frequency horn 470 are all located within housing 600.
- the first led 450 is located beneath plastic covering 650 so as to provide light in all directions for egress.
- the second LED 460 is located behind the translucent stylized fire symbol 660 (alternatively, the second LED 460 may also be located within housing 650).
- the housing 600 also includes a clock display 690 and associated control button panel 691 and hence can also serve as an alarm clock in some embodiments.
- Figure 7 illustrates a bed shaker housing 770 that is connected to the relay within housing 600 by a power cord (not shown in Figures 6 or 7).
- a tactile stimulation device other than a bed shaker may be utilized.
- switching devices such as relays, solenoids, and other types of switching devices may be used in place of the power FET to control activation of the bed shaker.
- Audible devices such as a low frequency buzzer may be used in place of the low frequency horn discussed herein.
- other non-continuous or interrupted repeating patterns may be used in place of the T-3 pattern. For example, a repeating temporal pattern consisting of more "on" periods than "off periods (or, alternatively, short and long "on” periods separated by short “off periods) can also be used. All such modifications are intended to be within the scope of the invention.
