The present invention relates to devices, systems, and methods for controlling humidity in a predefined area, such as a crib located in nursery.
In various aspects, humidity can have a significant impact on child health. For example, humidity can be especially important during the winter months when there is a higher incidence of colds and drier indoor air due to use of heat. To that end, low humidity is associated with increased respiratory and skin infections while high humidity can lead to dust mites and mold. Furthermore, maintaining an ideal humidity level is particularly important for babies younger than one years old since they cannot breathe through their mouth. To help babies breathe, many parents buy humidifiers. However, current humidifiers have significant shortcomings that are not being currently addressed, including, but not limited to the ability to regulate a predefined area in a room, such as a crib, while minimizing mold growth from standing or pooled water associated with using the humidifier.
Accordingly, there remains a need for an improved humidifier device and system for a predefined area that easily allows an individual to install, deploy, and regulate humidity of a specific portion of a room, such as a crib in a nursery. Such a humidifier device and system would preferably comprise a removable, dishwasher-safe tank and comprise a design to eliminate or substantially eliminate mold growth associated with standing water or accumulated water within the humidifier. This need and other needs are satisfied by the various aspects of the present disclosure.
In accordance with the purposes of the invention, as embodied and broadly described herein, the invention, in one aspect, relates to a humidifier device and system, and methods of regulating humidity of a specific portion of a predefined area, such as a crib in a nursery.

As briefly described above, the present disclosure provides, in various aspects, a device and system for providing and/or controlling humidity in predefined areas. This overview is provided to introduce a selection of concepts in a simplified form that are further described below. This overview is not intended to identify key features or essential features of the claimed subject matter. Nor is this overview intended to be used to limit the claimed subject matter's scope.
In one aspect, the disclosed humidifier device and system can provide a convenient system that can be capable of being installed in a room to provide deployable humidity to create and regulate a micro-climate in a predefined microenvironment portion of the room, such as within a crib. The humidifier device and system can be easily installed and deployed by a single user for maintaining desired humidity levels. In further aspects, the invention can maintain an optimal relative humidity (RH) level in the air in the predefined area a fixed distance away from the humidifier device. For example, in some embodiments, the invention can be used in a baby's nursery to keep the crib microenvironment at a comfortable or prescribed humidity level. The present invention employs various technologies for controlling the micro-climate, including, but not limited to, artificial intelligence (AI), machine learning techniques, control strategies, predictive modeling and/or various algorithms. In some aspects, the present invention can combine closed loop control with the various technologies for estimating and controlling humidity level at the end user. In other aspects, the present invention can combine gas diffusion dynamics, knowledge of the distance to the target, and measurement of a room's ambient humidity by the sensors and filtering with a proportional integral controller with anti-windup consideration for estimating and controlling humidity level at the end user.
In various aspects, the invention is capable of atomizing water from a removable, dishwasher-safe tank and propelling it into the air using an air source, such as a fan, in a predetermined flow path in the direction of the target area. In some aspects, the output direction can be chosen by the user, for example, via a rotating output head. In other aspects, the output direction can be determined by the control unit, for example, by automatically adjusting output direction via a rotating output head. In still further aspects, the device may be capable of sensing, or otherwise determining, a relative humidity (RH) level at using humidity data or temperature data detected at one or more points corresponding to sensor positions of two or more sensors. For example, using a low pass filtered average of two sensors measurements as the value for a room's ambient relative humidity, steady state modeling with a fixed humidity density at the output of the vapor source, along with the fixed target distance, the device can estimate the RH level in the target area and adjust the rate of humidity output proportionately.
In further various aspects, the present invention addresses various shortcomings of many existing humidifiers which lack the ability to control the humidity at a specific point in a room. To this end, many existing humidifiers sense the humidity at one point on the machine and output water vapor until the whole room is at the target humidity, wasting water and energy, or only have the output rate adjustable, which can either lead to too little or too much humidity in the room. Furthermore, many existing humidifiers are difficult to clean and prone to mold buildup due to standing water or pooling water generated during operation. As disclosed herein, various embodiments of the present invention can address these shortcomings by one or more of the following: having a removable water tank that can be dishwasher safe, eliminating or substantially eliminating small unreachable crevasses in the device were water can pool or building, and implementing a control strategy of ejecting all liquid in the humidity unit as water vapor or transporting the liquid back into the tank for storage. In further aspects, the only standing water present in the device is in the tank, which can prevent mold from growing in the device components that the user cannot put in the dishwasher. Still further, various embodiments of the present invention can include a door or an accessible opening that the user can use to access the humidity unit, the vapor source, and/or internal portions, such as the transducer, actuator and/or output components in the housing for easier cleaning.
In various further aspects, the present disclosure provides a humidifier system comprising a humidity device comprising at least one humidity unit. The humidity unit may comprise a vapor source configured to produce water vapor or moisture, and an airflow source configured to produce airflow. The humidity unit may be configured to produce humidified air for controlling relative humidity in the predetermined portion of a room, for example, by regulating the vapor source and airflow source. The humidified air produced may be configured to travel in a predetermined flow path along an output axis towards a target point. In further aspect, the humidity device may comprise a plurality of sensors. At least one sensor may be configured to measure absolute humidity data and/or temperature data. In still further aspects, each sensor located at different, predetermined positions. In even further aspects, the humidity device may comprise a control unit in operative communication with the humidity unit for controlling operation of the humidity unit. In yet further aspects, the humidity device may include a housing for containing the device components, such as the humidifier unit, plurality of sensors, and control unit. In still further aspects, the humidity device may comprise a tank configured to removably couple with the housing. The tank may be configured to contain a fluid, such as water, for producing a mist, moisture or water vapor, or the like.

In further aspects, humidity device may further comprise at least one pump in fluid communication between the vapor source and the tank. The pump may be configured to move the fluid from the tank to the vapor source and from the vapor source to the tank. The pump may be configured to transport a predetermined amount of fluid to the vapor source. In still further aspects, the pump may be configured to transport a predetermined amount of fluid to the vapor source corresponding to the amount of desired water vapor production. In yet further aspects, the pump may be configured to transport excess fluid from the vapor source back to the tank. In yet further aspects, the pump may be configured to transport fluid from the vapor source back to the tank when the vapor source is off. The pump may be configured to remove standing fluid from the vapor source back to the tank when the vapor source is not producing water vapor. In some aspects, the pump is a peristaltic pump.
In further aspects, humidity device may further comprise at least one fluid level sensor (which may also be referred to herein as a water level sensor) configured to determine a volume of fluid in the vapor source. The fluid level sensor may be configured to determine if a sufficient volume of fluid is present in the vapor source effective to allow a predetermined volume of water vapor production. In still further aspects, the fluid level sensor and pump may cooperate to transport fluid between the vapor source and the tank. In yet further aspects, the fluid level sensor and pump may cooperate to transport fluid from the vapor source back to the tank when the vapor source is off or not producing water vapor.

In other aspects, the fluid level sensor may comprise a plurality of wire probes behind the transducer connected by a resistor ladder and a de-noising capacitor.
In further aspects, the humidity device may further comprise a tank switch configured to determine an installation status of the tank. The tank switch may comprise a pushbutton switch with a roller arm that is deflected upon full insertion of the tank into the machine.
In further aspects, various embodiments of the present invention may comprise vapor source or unit configured to produce water vapor or moisture. In still further aspects, the vapor source may be in fluid communication with fluid in the tank, which may contain water or other desired fluid. In yet further aspect, the vapor source may be configured to atomize the fluid from the tank. The vapor source may be configured to produce water vapor without requiring a standing pool of fluid.
In various aspects, the vapor source may comprise an actuator and/or transducer. The transducer may be configured to produce a fine mist from a fluid. The vapor source may comprise a transducer configured to produce a fine mist without a standing pool of fluid. To this end, the vapor source and a fluid source may be in separate locations, for example, such that a transducer is not required to remain in a pool of water in order to produce water vapor. In some aspects, the vapor source consists of a transducer configured to produce a fine mist without being submerged in a standing pool of fluid.
The vapor source may comprise a mesh transducer. The mesh transducer may comprise, such as, for example, a piezoelectric ceramic mesh disk or the like. The transducer or piezoelectric ceramic mesh disk may be capable of temporarily deforming in a direction when a voltage is placed across it. In some aspects, the piezoelectric ceramic mesh disk may comprise small holes configured to create fine droplets using the fluid from the tank. The small holes may be from about 1 to about 40 μm, for example, from about 1 to about 20 μm or from about 6 to about 15 μm, and including any subranges therebetween. The piezoelectric ceramic mesh disk may be configured to produce oscillations from sine wave input effective to cause droplets of the fluid to be propelled into the air. In further aspects, the actuator may utilize various output control mechanisms. In still further aspects, the actuator may use a variable amplitude, fixed frequency sine wave, variable frequency and/or variable duty cycle signals, which can be generated by many different circuit topologies. Instead of traditional cavitation transducer, which is placed a fixed distance under a standing pool of water, various embodiments of the present invention may employ mesh transducer configured to be placed between the fluid in the tank and the air outside. The foregoing vapor source arrangement may be effective to eliminate standing water anywhere in the machine except for the tank, which will prevent mold buildup in areas outside of the tank. In further aspects, various embodiments may comprise an airflow source or unit to carry or propel water vapor produced by the vapor source out of the housing. In still further aspects, the airflow source may be capable of propelling or moving water vapor at a predetermined velocity along a predetermined flow path. In yet further aspects, the airflow source may comprise a fan or the like, for example, a DC fan.
In further aspects, the device and system may comprise a plurality of sensors. In yet further aspects, the device and system may include a sensor array comprising a plurality of sensors. In even further aspects, each sensor may be configured to measure absolute humidity data and/or temperature data. In some aspects, two or more sensors may be located at different, predetermined positions, for example, along a shared plane. In other aspects, two or more sensors may be located at different, predetermined positions along a shared plane corresponding to the output axis. In further aspects, A sensor may be located a minimum distance from other sensors. In still further aspects, one or more sensors may be located or positioned behind the output location of the vapor source. In yet further aspects, one or more sensors may be located or positioned behind and above the output location of the vapor source. In yet further aspects, the plurality of sensors consists of two sensors located or positioned behind and above the output location of the vapor source.
In further aspects, the device and system may include additional sensors that are not located along the output axis, such as one or more remote sensor located within and/or outside the target portion (e.g., crib) of the area (e.g., room). In further aspects, the sensors may be configured to measure both humidity data and temperature data. The measured humidity data and temperature data may be used to determine a relative humidity (RH) level. The sensors may be in operable communication with the control unit. In further aspects, the system may be configured to sense a plurality of relative humidity levels at a plurality of points along the output axis. In various aspects, the system is configured to sense relative humidity levels at multiple different points in the area and/or along the output axis using multiple sensors. In some embodiments, the plurality of sensors may comprise a first sensor and a second sensor. In other embodiments, the plurality of sensors may comprise a first sensor and a second sensor, and a remote third or fourth sensor. In further aspects, the system may be configured to sense relative humidity levels at two different points along the output axis using the first and second sensors. In still further aspects, the system may be configured to sense relative humidity levels at two different points within and/or outside the target portion of the area using a remote third and/or fourth sensors. In even further aspects, the system and device controlling operation of the humidifier device may be based at least on absolute humidity data and/or temperature data from the plurality of sensors. The measured data, such as the humidity data and temperature data, may further comprise using a low pass filter. For example, the determined relative humidity (RH) level comprises an average of the measured humidity data and temperature data from the plurality of sensors.
In yet further aspects, the plurality of sensors can comprise at least one additional sensor selected from one or more of: a boost rail voltage sensor, transducer sine wave amplitude sensor, or fan current sensor, or combinations thereof. The boost rail voltage sensor may be configured to monitor the actual voltage at the output of the DC/DC boost converter. In some embodiments, a boost converter is operated in an open loop manner. The resistance on the bottom leg of the voltage divider of the reference pin on the boost converter IC may be controlled via a digital rheostat. By changing this resistance, it can be expected for the boost converter to change its output proportionally. In order to achieve tighter control of this boosted voltage, some embodiments may incorporate a voltage sensor at the boost rail and implement a form of feedback control. To this end, it is believed this would allow for more information about the vapor output, since the amount of water droplets ejected by the transducer is proportional to the amplitude of the AC waveform placed across the transducer's terminals. In further aspects, the transducer sine wave amplitude sensor maybe configured in parallel with the transducer to gain information about the waveform downstream of the resonant circuit. It is believed to be able to enable better knowledge about the amount of mist being ejected, which could be used to implement feedback control of the transducer. In yet further aspects, the fan current sensor may be incorporated for tighter control of the air flow source, (i.e., DC fan) responsible for establishing the airstream of the flow path of the humidified air.
In further aspects, the device further comprises a control unit in operative communication with the humidifier device or unit for controlling operation of the humidifier device or unit. The control unit may be in operative communication with the vapor source and/or airflow source for controlling operation of the vapor source and/or airflow source. Controlling operation of the vapor source and/or airflow source may be based at least on absolute humidity data and/or temperature data from the plurality of sensors.
In yet further aspects, the control unit may comprise or otherwise use at least one control strategy for operating the humidifier device or unit. The control strategy may comprise a low pass filtered average of the output data of plurality of sensors, for example, two sensor measurements as the value for the room's ambient relative humidity, and model in the steady state with a fixed humidity density at the output of the vapor source. To this end, it has been surprisingly discovered that with knowledge of the distance to the target point (i.e., a crib in a room), the control unit of the humidity device can control the ambient humidity of the target point using the dynamics of gas diffusion and the air source speed (i.e., fan speed) dictating the path of the vapor output. In further aspects, the output velocity of the air source output and/r the flow path of the water vapor output in the control strategy may be modeled as a parabolic arc. In even further aspects, the air source speed (i.e., fan speed) in the control strategy may be calculated or determined to ensure mist delivery to the proper target location.
In still further aspects, the control unit comprises a microcontroller, a DC/DC variable boost circuit, and/or an oscillator circuit for driving an actuator. The control unit may further comprise a user interface for communicating with and/or allowing a user to interact with the device. The user interface may comprise an LCD screen and/or any I/O devices, such as switches, buttons, or dials or the like, capable of communicating with the end user and/or controlling one or more function of the device.
In various aspect, the system and device may use various technologies in connection with performing different operational functions, including, but not limited to, artificial intelligence (AI), machine learning techniques, predictive modeling/analytics and/or various algorithms. For example, the system and device may use various algorithms, predictive analytics, AI and machine learning techniques to search the room for sensors and determine their location and/or distance relative to the machine and/or other sensors, such as integrated sensors in the housing. Still consistent with embodiments of the present disclosure, the system and device may receive data as it tracks and/or monitors the micro-climate (i.e., temperature, humidity, etc.) while controlling or regulating one or more microclimate of the microenvironment within the room. In further aspects, the system may be configured to use sensed RH values and a preprogrammed knowledge (e.g., user entered) or calculated knowledge (e.g., determined by the device) of the distance between two or more sensors along with a fixed target predetermined portion distance to estimate a RH level in the predetermined portion of a predefined space. For example, the system may be configured to use two sensed RH values and a preprogrammed knowledge of the distance between the first and second sensors positioned in the housing along with a fixed target distance (measured, estimated, or user provided) to estimate a RH level in the predetermined portion of the predefined space. The system may be configured to use the estimated RH level in the predetermined portion of the predefined space for controlling the humidity unit, for example, for controlling the rate of humidity output. In still further aspects, the system may be configured to use the estimated RH level in the predetermined portion of the predefined space for controlling humidity/moisture and/or airflow rate of the humidified air outputted from the humidity unit. In some embodiments, real-time sensed and calculated data may be combined with historical data, and/or biometric data, retrieved from remote sensors and/or wearables. The combination may then be used to identify microclimate characteristics and patterns within the microenvironment. Such characteristics and patterns may be identified by performing predictive analytics and/or machine learning over the historical data. In other embodiments, the system may construct a prediction model that may determine microclimate status and necessary adjustments to the microenvironment.
To this end, the system may be configured to allow use of water more efficiently, yielding a longer runtime for the same tank capacity, and able to avoid the negative effects of humidity levels being too high or too low, propensity to mold growth in the room and respiratory discomfort respectively.
In further aspects, the invention may comprise a housing for containing the various components, such as the vapor source, airflow source, plurality of sensors, and/or control unit. In some embodiments, the housing may comprise a rotating output head configured to control an output direction of the humidified air. The output direction of the humidified air may correspond to the output axis. The output head may be configured to be rotated about an axis by a user to control the output direction. In some aspects, the output head may have sensors configured to located in the same plane as the output axis. In yet further aspects, the housing may comprise an output shaft configured to carry the humidified air along the predetermined flow path. The output shaft may be connected to the output head, and may further include an access door for easy access. For example, in some aspects, the output shaft may comprise an access door on the front which can be opened so the output shaft can be accessed more easily for cleaning.
In further aspects, the device may further comprise at least one tank to contain a fluid for producing moisture or water vapor. The tank may be configured to removably couple with the housing. In still further aspects, tank may be removable and dishwasher safe. In yet further aspects, the tank does not comprise small, hard to reach, crevasses. In some aspects, the tank may be made from a non-opaque material, so that the user can visually verify the water level. Still further, the system may use a tank interfacing component configured to fix the tank in place such that no water leaks until the user removes it. To this end, the system may be configured to position the transducer within the tank on the boundary of the fluid and free air. Due to the different transducer being used and its different location requirements relative to the water in the tank (on the boundary of the water and the free air, as opposed to submerged under the water), the system is less likely to accumulate water or mold.
In various aspects, the device component characteristics and configuration, such as, for example, size and dimensions, can be configured to adjust for an intended area, individual user's characteristics, and other factors to achieve optimal humidity regulation. In further aspects, features of the device and components, such as the tank size and output connections, may be configured or utilized to set and/or control the micro climate characteristics. In further aspects, while the vapor source and/or airflow source described herein can be permanently mounted in or on the device housing or device structure, this is not a requirement. In still further aspects, one or more vapor sources and/or device elements can be detachably connected to the housing, e.g., to allow interchange and/or replacement of one or more elements. Such configurations allow users to select desired humidity level and room properties, e.g., for customization purposes, for personal preferences, to match desired treatment use, a subject's physical characteristics, a subject's symptoms, or to repair or replace defective or damaged device component, etc.
In further aspects, the disclosed humidifier devices and systems may further comprise one or more of the following components: a voltage regulator, power switch, power management module, antenna (e.g., Bluetooth LE antenna), transceiver (e.g., Bluetooth LE transceiver), motor controller, interface module, control module, voltage sensor, current sensor, pulse-width modulation (PWM) module, power input, magnetic switch, motor control module (e.g., actuator control module), and motor drive. In still further aspects, a number of internal components may be mounted within an interior portion of the device and/or housing. For example, in some embodiments, the device may have an internal component configuration further comprising a controller containing a processing unit, battery back, voltage regulator, power switch, battery management module (e.g., fuel gauge), antenna (e.g., Bluetooth LE antenna), and transceiver (e.g., Bluetooth LE transceiver).

In further aspects, humidifier device 100 generally produces humidified air using the water droplets atomized by an actuator contained within vapor source 104 which are carried by the airflow produced by the fan of airflow source 106. The primary actuator is mesh transducer, specifically a piezoelectric ceramic mesh disk with small (6-15 um) holes configured to create fine droplets using the fluid transported from tank 114.

As described herein, the humidifier device 100 comprises a control unit 110 with a microcontroller, in operative communication with the humidifier unit 102 for controlling operation of the vapor source and airflow source. Controlling operation of the vapor source and/or airflow source may be based at least on absolute humidity data and/or temperature data from sensors 108. Control unit may use a control strategy for operating the humidifier unit. The control strategy comprises a low pass filtered average of the output data of sensors 108, for example, two sensor measurements as the value for the room's ambient relative humidity, and model in the steady state with a fixed humidity density at the output of the vapor source. To this end, it has been surprisingly discovered that with knowledge of the distance to the target point (i.e., a crib in a room), the control unit of the humidity device can control the ambient humidity of the target point using the dynamics of gas diffusion and the air source speed (i.e., fan speed) dictating the path of the vapor output. In further aspects, the output velocity of the air source output and/r the flow path of the water vapor output in the control strategy may be modeled as a parabolic arc. In even further aspects, the air source speed (i.e., fan speed) in the control strategy may be calculated or determined to ensure mist delivery to the proper target location. To this end, control unit 110 includes a proportional integral controller with anti-windup consideration.
Plant: the target location, and describing dynamics model what happens to the room when mist is ejected into it by the device 100.
r: reference command—the desired ambient relative humidity of the room, which is dictated by the distance from the device 100 to the target point (this calculation is done in the reference selector).
y′: plant output—actual relative humidity at the machine.
y: measured plant output—measured relative humidity from the machine after low pass filtering.
u: actuator input—mist being ejected into the room.
w: disturbances to the system—anything not accounted for in the first order approximation of the diffusion dynamics (e.g., air flowing in from a vent, someone walking in front of the device).
v: sensor noise—inaccuracies from sensor non-idealities.
σ: error integrator—this is the cumulative error over time; adding the integral term can ensure zero steady state error.
e: error between the reference command and plant output
u′: actuator request—requested amount of mist
u: actual actuator input—saturated because the transducer can only output between 0 and 100% (e.g., if request was for 200% or −10% power the actual input would be saturated to 100% and 0% respectively).
awf: anti-windup flag—This stops the error integrator from increasing when the actuator is saturated.

The relative humidity level of the target portion may be determined based at least on two or more sensed RH values and a preprogrammed or system-determined knowledge of the distance between first and second sensors along with a fixed target distance to the predefined target portion.

After stage 1050, method 1000 may end at stage 1060 or return to step 1020 to determine current RH level. Steps 1020 through 1050 may be repeated until the target relative humidity level is reached or within a desired range. For example, if the target relative humidity level determined during step 1020 falls out of the desired range, method can begin again at step 1030.
