## Background
FIELD
The disclosure relates in general to sleep disorder prevention, and more particularly to, a sleep apnea avoidance and data collection device.
BACKGROUND
Many people suffer from sleep disorder that can make them feel tired the next day, even after a full night sleep. Sleep apnea may be a potentially serious sleep disorder and may include obstructive sleep apnea or central sleep apnea. The obstructive sleep apnea may occur when throat muscles relax and makes breathing difficult. In the central sleep apnea, on the other hand, the brain may stop sending proper signals to the muscles that control breathing. Sleep apnea, in particular, the obstructive sleep apnea, which is more common, may be recognized by one or more symptoms, for example, loud snoring.
Obstructive sleep apnea may be attributed to excess weight, especially fat deposits around upper airways, a narrowed airway, family history, age, race, and other factors. Most people with obstructive sleep apnea symptoms such as snoring may by sleeping in a particular position that, for example, the relaxed throat muscles can partially block the airway. For instance, in many people snoring may occur when they sleep on their back and if they change sleeping position and sleep on their sides, the snoring may stop. Therefore, there is a need for a device that can cause a sleeping person to change sleeping position, even without being awakened.
SUMMARY
In one aspect, a device for sleep apnea avoidance and data collection may include a sensor configured to sense a pressure and generate a first signal when the pressure exceeds a threshold. A signal generator module may be configured to generate a first stimulating signal in response to the first signal. The sensed pressure may include a pressure exerted on the sensor when a user of the device lies down on the device. The first stimulating signal is configured to cause the user to change sleeping position, for example, from a first sleeping position that causes snoring to a second sleeping position that stops snoring.
In another aspect, a method for sleep apnea avoidance and data collection may include configuring a sensor to sense a pressure and to generate a first signal when the pressure exceeds a threshold. A signal generator module may be configured to generate a first stimulating signal in response to the first signal. The first stimulating signal may be configured to cause the user to change sleeping position, from a first sleeping position that causes snoring to a second sleeping position that stops snoring. The sensed pressure may include a pressure exerted on the sensor when a user of the device lies down on the device.
In yet another aspect, a device for communicating with a sleep apnea avoidance device may include a communication module configured to wirelessly communicate with the sleep apnea avoidance device. An interface module may be configured to provide one or more user interfaces. The user interfaces may be configured to receive user inputs from a user including a user of the sleep apnea prevention device. The user inputs may be used for communication to the sleep apnea avoidance device. The user interfaces may display information received from the sleep apnea avoidance device.

FIGS. 1A-1B are conceptual diagrams illustrating examples of a device 100 for sleep apnea avoidance and data collection. In the diagram shown in FIG. 1A, the device 100 is illustrated to be used in a pocket 112 of a pad 110. The pad 110 may be wearable by the user, for example, may have an adhesive layer, for instance, on the back of the pad 110, which can allow the pad 110 to be safely adhered to and removed from the human skin, similar to the existing wound bandages. The pad 110 may be adhered to any part of the body, in particular on the part of the body that when the user sleep on that part, sleep apnea symptoms such as snoring happens, for example, on the back of the user. It is understood that many people have sleep apnea symptoms (e.g., snoring) when sleeping on their back.
In one or more aspects, the device 100 may be worn in a pocket of an under-wear such as a T-shirt, sleepwear, and the like. The pocket may be on a suitable position on the under-wear, for example, on the back of the under-wear, if the user snores when sleeping on her/his back. The device 100, although shown as a thin disk, may be built in any shape and size that would be comfortable to wear when sleeping. In one or more implementations, the device 100 may be built in a flat form with various shapes and may have a thin (e.g., a few mms) and flexible packaging.
In one or more implementations, as shown in FIG. 1B, the device 100 may be able to communicate with another device (e.g., an external device), for example, a handheld device 120 such as a wireless communication device including a mobile phone, a personal digital assistant (PDA), a tablet, a phablet, or a personal computer 130 such as a laptop and the like. The device 100 may be configured to collect data including history information related to the use of the device 100 by the user, and to communicate the collected data to the other device. The device 100 may also be able to receive from the other device user input information. The device 100 may be able to communicate with the other device through a wireless network, such as Wi-Fi, WLAN, PAN, WAN, and the like, via near-field-communication (NFC), or other network technologies. In one or more implementations, the device 100 may include a rechargeable battery that can be wirelessly charged from the other device, for example, the handheld device 120 or the personal computer 130.
FIG. 2A is a block diagram illustrating an example structure of the device 100 for sleep apnea avoidance and data collection of FIGS. 1A and 1B. The device 100 may include, but not be restricted to, a sensor 140, a signal generator (also called “signal generator module”) 150, an audio alarm generator 160, a communication (also called “communication module”) 170, a power supply 180, and a monitoring module 190. The monitoring module 190 may include a threshold generator (also called “threshold generator module”) 192 and a counter also called “counter module”) 194. The sensor 140 may include a pressure sensor, such as a thin film pressure sensor, for example, a piezoelectric, piezo-resistive, capacitive, electromagnetic, optical, or other type of pressure sensor. In one or more implementations, the sensor 140 may be integrated with other electronic components of the device 100 such as the signal generator module 150, communication module-170, monitoring module 190, and other electronic components, for example, on a the same chip (e.g., a semiconductor chip, such as a silicon chip).
The sensor 140 may be configured to sense a pressure exerted on the sensor when a user lies down on the device 100. The sensor 140 may generate, in response to the sensed pressure exceeding a threshold, a first signal that is received by the signal generator module 150. The threshold may be set by the user through a user interface of the other device (e.g., the handheld device 120 or the personal computer 130). In an aspect, the threshold module 192 may be configured to set (e.g., generate) the threshold when the user lies down on the device for a first time, on a designated bed (e.g., a user's bed). For example, the user may inform the device 100, using the other device, when the user uses the designated bed and lies down, for the first time, on the device 100. This is because the pressure exerted on the sensor 140 may depend on the softness/firmness of the bed that the user is using.
In one or more aspects, the user may set the threshold through a user interface of the other device (e.g., handheld device 120). The other device 100 may communicate the threshold setting to the device 100, where the threshold module 192 receives the threshold setting communicated by the other device and uses the threshold setting to set the threshold of the sensor 140. The threshold may be changed by the user, for example, when the user becomes more sensitive to the first signal or when the softness/firmness of the bed may change. In some aspects, the threshold may be set or changed from the device 100.
The signal generator module 150 may generate, in response to the first signal, a first stimulating signal, which may cause the user to change sleeping position. The signal generator module 150 may include a signal generator circuit 152 and a stimulator transducer 154. The signal generator circuit 152 may generate the first stimulating signal that includes electrical signals such as electrical pulses that are applied to the stimulator transducer 154. The first stimulating signal may include different types, each type, for example, identified by a specific signal waveform, such as rectangular, sawtooth, triangular, pulse, and the like. The first stimulating signal may also have attributes including, but not limited to, frequency, duty cycle, and magnitude. The signal generator circuit 152 may stop generating the first stimulating signal in response to a stop signal from the sensor 140 when the user changes sleeping position from a first sleeping position that causes snoring to a second sleeping position that stops snoring. The signal generator module 150 may generate the first stimulating signal based on the information related to the selected stimulating signal received from the other device (e.g., the handheld device 120 or the personal computer 130 of FIG. 1B). The user may employ a user interface (e.g., a second user interface) on the other device to input information related to a selected first stimulating signal including, but not limited to, the type, the magnitude, the frequency, and the duty cycle.
The stimulator transducer 154 may use the stimulating signals (e.g., the first stimulating signal) to generate vibrational or tickling stimuli that can make the user change sleeping position. The stimulator transducer 154 may be similar to or be the same as the sensor 140, which can have dual functionality and work as both a pressure sensor and a stimulator transducer. For example, a piezoelectric thin film may be able to have the dual functionality of a pressure sensor and a stimulator transducer. In one or more aspects of the subject technology, the stimulating transducer 154 may be separate from the sensor 140.
The counter module 194 may start measuring an elapsed time in response to the first signal, and may generate a first change signal when the elapsed time reaches a first preset value. The counter module 194 may generate a second change signal when the elapsed time reaches a second preset value. The first and the second preset values may be set by the user by employing a user interface of the other device. The signal generator module 150 may generate a second stimulating signal and a third stimulating signal in response to the first and second change signals received from the counter module 194. The information related to the second and third stimulating signals and the first and second preset values may be received from the other device. The user may provide the information related to the second and third stimulating signals and the first and second preset values through one or more user interfaces of the other device. The second and third stimulating signals, similar to the first stimulating signal, may be identified by a number of attributes including, but not limited to, a frequency, a duty cycle, a magnitude, and a type, as described above.
The audio alarm generator 160 may generate an audio alarm signal based on the information related to an audio alarm signal received from the other device. The information related to the audio alarm signal may include, but not limited to, a type, a volume, and a trigger event. The trigger event may indicate a trigger event for activating the audio alarm signal. For example, the trigger event may include non-responsiveness of the user to the first, second and third stimulating signals. That is to say, if the user did not change position in response to the stimuli generated as the result of the first, second, and third stimulating signals, the monitoring module 190 may send a trigger signal to the audio alarm generator 160 to start an audio alarm signal that may awaken the user. It is understood that the attributes of the first, second, and third stimulating signals may be set by the user so that these stimulating signal does not awaken the user and just make the user to change position.
The communication module 170 may include a wireless transmitter that can communicate with the other device via a wireless network, such as Wi-Fi, WLAN, PAN, WAN, and the like, via near-field-communication (NFC), or other network technologies. For example, the communication module 170 may be configured to receive information from the other device. The information received from the other device may include information related to a use of a bed including the information indicating the bed as the designated bed and the first time that the designated bed is used by the user. The information may include information related to the threshold set by the user using a first interface on the other device, the selected first stimulating signal, the audio alarm signal.
The communication module 170 may be configured to transmit to the other device history information. The history information may be stored in the other device and may be displayed to the user upon request. The history information may include a date, a start time and a stop time for each of the first, second, and third stimulating signals, and the audio alarm signals that were generated, each time the device was used by the user.
The power supply module 180 may include a voltage regulator and a power source such as battery, including a rechargeable battery. The voltage regulator may provide the electrical power for device 100. In one or more implementation, the rechargeable battery of the power supply 180 may be wirelessly rechargeable from, for example, the other device.
FIG. 2B is a time diagram 200B illustrating an example of the functionality of the device 100 for sleep apnea avoidance and data collection of FIG. 2A. The time diagram 200B shows the interaction between various components and modules of the device 100. Various operation blocks are executed as shown from top to the bottom of the diagram as the elapsed time increases. At operation block 210, the sensor 140 of FIG. 2A may sense a pressure exceeding the threshold set by the user of device 100, and in response, the sensor 140 may generate the first signal, which is received by the signal generator module 150 of FIG. 2A. At operation block 220, the signal generator module 150 may generate the first stimulating signal. At operation block 230, the counter module 194 may start counting the elapsed time after issuing of the start signal by the signal generator module 150, in response to the start signal received from the signal generator module 150.
At operation block 212, the sensor 140 may sense a pressure less than the threshold, which indicates that the user has changed sleeping position and is not sleeping over the device 100 any longer. The sensor 140 may then send a stop signal to the signal generator 150, and the signal generator 150 may stop the first stimulating signal, at operation block 212, and send an end signal to the counter module 194. The counter module 194, in response to the end signal, at operation 232, may determine the elapsed time, which in this case is determined to be less than the first preset value set by the user.
At operation block 214, the senor 140 may sense a pressure higher than the set threshold, and may send the first signal to the signal generator module 150, which in turn, at operation block 224, may generate the first stimulating signal and issue a start signal to the counter module 194. In this scenario, the user does not respond to the first stimulating signal and the counter determines, at operation block 236, that the elapse time after the start signal has exceeded the first preset value. The counter module 194, may restart and issue a first change signal, in response to which, the signal generator 150, at operation block 226, may start the second stimulating signal. The second stimulating signal may be different from the first stimulating signal, for example, having a different type of waveform, or being stronger in terms of magnitude, having a different frequency or duty cycle so that it is perceived by the user to be more stimulating or alerting.
If the user does not respond to the second stimulating signal and the counter module 194, at operation 238, determines that the elapsed time after the start of the second stimulating signal has surpassed a second preset value, the counter module 194 may restart and issue a second change signal to the signal generator 150. In response to the second change signal, the signal generator 150, at operation block 228, may start a third stimulating. The elapsed time form the start of the third stimulating signal may is measured by the counter module 194. At operation block 240, the counter module 194 may determine that the elapsed time after the start of the third stimulating signal has exceeded a third preset value.
At this time the counter module 194 may issue an alarm start signal that is received by the audio alarm generator 160 of FIG. 2A. The audio alarm generator 160, at operation block 250, may play an alarm signal, which can make the user to change sleeping position. The alarm sound may be configured not to awaken or awaken the user. Once the user changes the sleeping position, the sensor 140, at operation block 216, may sense the change in pressure and may send an alarm stop signal that is sensed by both the signal generator module 150 and the audio alarm generator 160. At operation block 229, the signal generator module 150 may stop the third stimulating signal, and at operation block 252, the audio alarm generator 160 may stop the audio alarm signal. There may be other similar scenarios of interaction between the various components that are not shown here for simplicity.
