Patent Description:
Existing solutions for wearable sensor enclosures suffer from deficiencies. For example, existing solutions, which are typically designed for adult wearers, can be too large to use with children or infants. These solutions can include small parts which can break off, causing a hazard. Additionally, some existing solutions are shaped such that they can pose a safety or choking hazard in the event that the enclosure is placed in a child's mouth.

Additionally, existing solutions fail to indicate a preferred orientation of the wearable sensor enclosure. For example, if the orientation or alignment of the sensor is relevant for accuracy of the results, an incorrectly-positioned wearable sensor enclosure can result in the enclosed sensor detecting erroneous measurements.

Further, other housing solutions have sought to provide removable batteries. This can result in complexity of use and the battery compartment can provide an additional area for undesirable moisture ingress. Hence, new sensor enclosure solutions are needed.

<CIT> discloses a moisture detection apparatus that comprises a soft printed circuit board, a power supply, a processing unit, and a bendable body. A first housing member is integrally formed with the bendable body. A second housing member <NUM> can be fixed with respect to the body <NUM> and releasably engaged with the first housing member <NUM> to define a cavity.

<CIT> discloses a monitoring system that comprises a module having at least one sensor within a housing.

<CIT> discloses a reusable electronics enclosure adapted to be associated with an absorbent article and to be in contact with a sensor indicative of state of the absorbent article and comprising means for collecting data indicative of the state of the absorbent article. The electronics enclosure comprises a housing for enclosing electronic components, wherein the housing comprises at least a first and a second portion attached to each other for forming a water tight enclosure.

Features, embodiments, and advantages of the present disclosure are better understood when the following Detailed Description is read with reference to the accompanying drawings.

Certain aspects of the present disclosure relate to a wearable sensor enclosure, or housing. In use, the wearable sensor enclosure can be placed on an absorbent article such as a diaper or otherwise attached to a wearer. When properly located, one or more sensors housed inside the wearable sensor enclosure can measure one or more parameters of the wearer. Non-limiting examples of suitable parameters that may be measured include movement, moisture (e.g., humidity or wetness), a presence of a volatile organic compound (VOC), light, sound, temperature, or other parameters. In one example, electronic devices installed in the wearable sensor enclosure can transmit the parameters to an external device. Non-limiting examples of suitable external devices include a monitor, an external computing server, a tablet, a cell phone, or any other device that can receive transmission from the one or more sensors housed inside the wearable sensor enclosure.

Wearable sensor enclosures can enable improved monitoring by enabling the placement of electronic sensors on an article of clothing or an absorbent article. For example, an accelerometer or gyroscope within the wearable sensor can detect movement of an infant and can detect, in conjunction with an external device, whether the infant is asleep, awake, or nursing. Wearable sensors can also measure parameters such as heartrate, breathing rate, or determine whether an infant's diaper needs to be changed. Wearable sensor enclosures facilitate such measurements while ensuring the sensors are protected and that the wearable sensor enclosure itself and its contents do not cause a hazard to the wearer.

Turning now to the figures, <FIG> depicts wearable sensor enclosure <NUM>, which includes a distal component <NUM> and a proximal component <NUM>. The distal component <NUM>, or lower housing, is generally the component that is oriented away from the wearer (or away from a diaper) while the sensor is in use. The distal component <NUM> is shown as having a first section, which may also be referred to as a protrusion <NUM>, positioned in the interior of the distal component <NUM> with respect to a second section, which may be referred to as an outer lip <NUM>. The protrusion can protrude upwards, defining an internal cavity on an under surface of the distal component <NUM>. This internal cavity can facilitate room for an electronic circuit, one or more sensors, or any other electronic component to be placed on the interior of the wearable sensor enclosure <NUM>. The distal component <NUM> can also include outer lip <NUM>, that is positioned around a perimeter of the distal component <NUM>. As shown, the outer lip <NUM> can generally be thinner than the protrusion <NUM>. In this manner, the outer lip <NUM> creates a ridge, edge, or flange around at least one portion of the wearable sensor enclosure <NUM>.

The proximal component <NUM>, or upper housing, is generally oriented to face towards the wearer (or towards a diaper) while the sensor is in use. It can provide a base for the wearable sensor enclosure <NUM>. In some examples, the lower surface of the proximal component <NUM> is planar or otherwise flat so that it lies flush with the wearer, the diaper, or other measured surface. The proximal component is also shown as having openings <NUM> and <NUM>. Although two openings <NUM>, <NUM> are illustrated, it should be understood that fewer or more openings may be provided. In an example, openings <NUM>, <NUM> are cutouts. In another example, openings <NUM>, <NUM> are transparent windows through which light can enter into or exit the wearable sensor enclosure <NUM>.

In an exemplary use case, the wearable sensor enclosure <NUM> is placed on or affixed to an absorbent article such that the proximal component <NUM> is on the absorbent article and the distal component <NUM> is oriented away from a wearer of the absorbent article.

As discussed, in some cases, the wearable sensor enclosure <NUM> can indicate orientation as to aid with placing the wearable sensor enclosure <NUM> on an absorbent article or wearer in such a way that any sensors located within wearable sensor enclosure <NUM> are correctly aligned to enable an accurate sensor measurement to be taken. Because internal sensors are typically configured to be oriented in a particular direction, a lack of an orientation indicator can result in the wearable sensor enclosure, and therefore the internal sensors, being misaligned. As an example, the wearable sensor may detect wetness in an article or diaper by sensing change in color of a color change strip. In such cases, failure to properly align the wearable sensor over the color change strip can result in inaccurate sensor readings.

For example, the wearable sensor enclosure <NUM> can include one or more orientation markings (not depicted). In one example, the orientation marking can indicate a preferred orientation of the wearable sensor enclosure. The orientation markings may be positioned on the distal component <NUM>, protrusion <NUM>, or outer lip <NUM>, on the proximal component <NUM>, or any combination thereof. Non-limiting examples of orientation markings may include an arrow, a word, an animal, a shape, a letter of the alphabet, or any other marking that has a configuration or orientation that is easily detectable that it is right side up or upside down.

In another example, the wearable sensor enclosure can include a superior end and an inferior end that are opposite to each other. <FIG> illustrates a wearable sensor enclosure with a superior end and an inferior end. <FIG> depicts an example of a placement of the wearable sensor enclosure on an absorbent article.

Referring now to <FIG> and <FIG>, the assembled wearable sensor enclosure <NUM> is shown in front and side views. In other words, the distal component <NUM> and proximal component <NUM> are nested or otherwise secured to one another. As shown, the protrusion <NUM> of the distal component <NUM> can protrude upwards as to facilitate space for internal devices or sensors. In contrast, as shown in <FIG>, the outer lip <NUM> is narrow, having no electronic devices therein. A transition section <NUM> exists between the protrusion <NUM> and the outer lip <NUM>. The transition section <NUM> can form a concave curve. In some cases, the presence of outer lip <NUM> can facilitate air flow around the wearable sensor enclosure <NUM>, or the shape of this curve can create a channel of air in the event that the wearable sensor enclosure <NUM> is attempted to be swallowed or otherwise stuck with in an airway. This difference in shape between protrusion <NUM> and outer lip <NUM> can therefore provide an enhanced safety feature by minimizing a risk of choking in an event that an infant removes the enclosure and places it in his or her mouth.

Wearable sensor enclosure <NUM> can support any electronic devices housed within. For example, a printed circuit board (PCB) including a battery, sensor, antenna, processor, etc., can be placed between distal component <NUM> and proximal component <NUM>. A PCB can be mounted on distal component <NUM>, on proximal component <NUM>, or in between. Examples are discussed further with respect to <FIG>.

Different materials can be used for components of the wearable sensor. Such materials used can be hard (e.g., hold their shape) or soft (e.g., malleable). Examples of materials include plastic, elastomer, or rubber. In one example, the outer lip <NUM> is made of a hard material with an additional soft material covering the hard material. This layering of materials can help provide wearable sensor enclosure <NUM> with a softer feel while maintaining an internal structure to protect internal components.

In some cases, the proximal component <NUM> can include an adhesive or an attachment device that can adhere proximal component <NUM>, and thereby the wearable, to a wearer or an absorbent article. Examples of attachment devices include hooks and loops, buttons, snaps, adhesive stickers, or any combination thereof. In other cases, the proximal component <NUM> can attach to an adhesive surface.

In an example, the distal component <NUM> may contain a flexible outer material and an inner, hard material such as polycarbonate or triton. The inner material can help form a cavity within which the electronic devices are housed, hence causing a protruding area that helps define the protrusion <NUM>. In another aspect, distal component <NUM> and/or proximal component <NUM> can be made of a rigid material to protect any electronic devices present inside the wearable sensor enclosure <NUM>.

Examples of electronic devices that can be placed within the wearable sensor enclosure <NUM> include an accelerometer, gyroscope, an optical sensor, moisture sensor, sound emitting device, a temperature sensor, or any combination thereof. Additionally, the protrusion <NUM> can provide sufficient room for a printed circuit board that can include a battery, processor, integrated circuit, Light Emitting Diode (LED), or other components or any combination thereof.

In another aspect, the wearable sensor enclosure <NUM> includes a button area on the protrusion <NUM>. The button area can be created by forming protrusion <NUM>, at least in part, of a flexible material that can respond to movement. The button area can be any shape, for example, circular, square, or rectangular. In some cases, the one or more buttons can cause a device or switch inside the enclosure to be activated, which in turn can turn the electronic devices on or off. For example, a top of the distal component <NUM> can be made from a flexible material that can transmit a user's push or touch to a button or sensor located below, which in turn can open or close an electronic circuit, causing an action to be performed. Additionally, a transparent or partially transparent portion of the wearable sensor enclosure <NUM> can facilitate emitted light. Emitted light can indicate a status of the sensor to a user, e.g., whether the sensor is on or off, or is operating correctly.

Openings <NUM>-<NUM> (or sensor windows) facilitate light entering into or exiting from the wearable sensor enclosure <NUM>. For example, an optical sensor can receive light through one or more of openings <NUM>-<NUM>. In another example, an optical transmitter can transmit light through one or more of openings <NUM>-<NUM>. Emitted light can be useful for detecting color of an object, e.g., color strip in a diaper, below the sensor. For example, a light source can emit a light and detect a measurement of received light. From the received light, a processor can determine a measure or volume of bodily exudate present in a diaper. In yet another example, a humidity or volatile organic compound (VOC) sensor can analyze air that flows through one or more of openings <NUM>-<NUM>. Although two openings are shown, it should be understood that a single window or more than two windows may be provided. The windows may be formed as openings in the proximal component <NUM> that are overlaid with a transparent plastic, tempered glass, sealant, or any other material that will maintain watertight integrity of the wearable sensor enclosure <NUM> while also transmitting light wavelengths.

<FIG> depicts a top view of the wearable sensor enclosure of <FIG>, in accordance with an aspect of the present disclosure. More specifically, <FIG> depicts the wearable sensor enclosure <NUM>, superior end <NUM>, inferior end <NUM>, protrusion <NUM>, and outer lip <NUM>. As depicted, lines indicate a concavity formed between outer lip <NUM> and protrusion <NUM>, as protrusion <NUM> can protrude outward from outer lip <NUM>.

In some cases, the wearable sensor enclosure <NUM> can be oriented such that the superior end <NUM>, a wider end, is the top end and the inferior end <NUM>, a narrower end, is the bottom end. The narrower end can therefore provide a visual cue to orient the wearable sensor enclosure <NUM> such that the inferior end <NUM> is downward, e.g., towards an infant's legs, such that the superior end <NUM> is pointed upwards, e.g., towards an infant's belly button. In this manner, any internal sensors are correctly oriented with the wearer (e.g., vertically or horizontally). The narrower end can also provide a visual cue as to where the internal sensors lie inside wearable sensor enclosure <NUM> such that the sensors may be oriented over the color strip.

<FIG> depicts an exemplary placement of the wearable sensor enclosure of <FIG>, in accordance with an aspect of the present disclosure. <FIG> depicts wearable sensor environment <NUM>, which includes absorbent article <NUM> and wearable sensor enclosure <NUM>. The absorbent article <NUM> may be an infant diaper, child training pants, an incontinence diaper or brief (such as the type worn by a patient in a hospital or nursing home), a feminine article, a patient bandage or wrap, or any other appropriate article. Absorbent article <NUM> includes front <NUM>, rear <NUM>, color strip <NUM>, and tabs <NUM>, <NUM>. Tabs <NUM> and <NUM> can be an adhesive material that attach to absorbent article <NUM>. Absorbent article <NUM> is configured to receive tabs <NUM> and <NUM>, which keep the absorbent article <NUM> from slipping off a wearer.

Color strip <NUM> can be a color changing indicator that indicates a presence or volume of bodily exudate in absorbent article <NUM>. Color changing indicators are designed to change color in response to contact with a substance having a particular property, such as a pH level. Examples include be Bromocresol green, which changes color based on the pH of a liquid to which the color changing indicator has been exposed. Other color changing indicators can be used. The detected pH level can be correlated with a volume of bodily exudate, because the pH level changes as the volume of bodily exudate in the absorbent article changes.

Accordingly, wearable sensor enclosure <NUM> can be placed on absorbent article <NUM>, for example, over color strip <NUM>, such that wearable sensor enclosure <NUM> can detect a change in color strip <NUM>. Other exemplary placements include the front <NUM>, side, or rear <NUM> of the absorbent article <NUM>. As depicted, wearable sensor enclosure <NUM> is oriented such that the superior end <NUM> is pointed upwards towards a belly button or chest of the infant wearing absorbent article <NUM>, and the inferior end <NUM> is pointed downwards.

As discussed above in connection <FIG>, wearable sensor enclosure <NUM> can include one or more sensors. For example, if the one or more sensors include an accelerometer, when the wearable sensor enclosure <NUM> is placed on absorbent article <NUM>, the wearable sensor enclosure <NUM> can sense movement by the wearer of the absorbent article <NUM> or of the absorbent article <NUM> itself. If the one or more sensors include an optical sensor, the wearable sensor enclosure <NUM> can emit a light source onto absorbent article <NUM> and measure an amount or color of light reflected from absorbent article <NUM>. Such measurements can then be used to determine a presence, absence, or volume of moisture or bodily exudate such as blood, urine, or feces present in absorbent article <NUM>.

In some cases, the outer lip <NUM> varies in width. For example, a first distance can be measured from the perimeter of wearable sensor enclosure <NUM> to the protrusion <NUM> as measured at the superior end <NUM>. A second distance can be measured from the perimeter to the protrusion <NUM> at the inferior end <NUM>. When the first distance, e.g., at the inferior end <NUM>, is longer than the second distance, e.g., at the superior end <NUM>, the preferred orientation of the sensor is made clearer.

<FIG> depicts a view of the superior end of the wearable sensor enclosure of <FIG> from the perspective of the superior end, in accordance with an aspect of the present disclosure. <FIG> depicts the wearable sensor enclosure <NUM>, distal component <NUM>, proximal component <NUM>, and outer lip <NUM>. As depicted, lines indicate a concave curve between distal component <NUM> and proximal component <NUM>, through the transition <NUM>. In this manner, the transition <NUM> and/or the outer lip <NUM> create a ridge, edge, or outer flange. Examples of radii of curvature for the concave curve are <NUM>-<NUM>. Other radii are possible.

<FIG> depicts a side left view of the wearable sensor enclosure of <FIG>. <FIG> depicts the wearable sensor enclosure <NUM>, superior end <NUM>, inferior end <NUM>, distal component <NUM>, and proximal component <NUM>.

<FIG> depicts a bottom view of the wearable sensor enclosure of <FIG>. <FIG> depicts the wearable sensor enclosure <NUM>, superior end <NUM>, inferior end <NUM>, and proximal component <NUM>.

<FIG> depicts examples of electronic devices which can be placed inside the wearable sensor enclosure <NUM> of <FIG>. <FIG> depicts sensor system <NUM>, which includes one or more of button <NUM>, processor <NUM>, microcontroller <NUM>, transceiver <NUM>, Light Emitting Diode (LED) <NUM>, battery <NUM>, and color detector cell <NUM>, or any combination thereof.

Processor <NUM> can be an analog device or a digital device such as a processor. Examples of processors include general purpose processors, controllers, and signal processors.

Microcontroller <NUM> is configurable to control color detector cell <NUM> or other sensors such as volatile organic compound (VOC) sensors, accelerometers, gyroscopes, or humidity sensors.

Color detector cell <NUM> can transmit light or receive reflected light through one or more of openings <NUM>-<NUM>.

In an example, a color sensing application operating on microcontroller <NUM> causes LED <NUM> to emit a light on a color changing indicator in absorbent article <NUM>. Color detector cell <NUM> then measures an amount of received light reflected from the color changing indicator. Using the measurement, processor <NUM> disambiguates a contribution of ambient light and passes a measurement of the color of the light to microcontroller <NUM>. Microcontroller <NUM> determines, based on the color of the light, a presence and volume of bodily exudate present in the absorbent article.

In some cases, multiple color detector cells can be used. A presence of multiple color detector cells enables a calculation of multiple data points to more accurately estimate a total volume of bodily exudate present. Color detector cell detects light reflected by an object such as a color changing indicator in absorbent article <NUM>, such as ambient light or pulsed light from the light source(s). The output of color detector cell <NUM> is provided to processor <NUM>. The output of processor <NUM> can be provided to microcontroller <NUM>.

In some cases, battery <NUM> can be disposable with an exemplary life of three to six months, removing the need for a charging system. In other cases, battery <NUM> can be rechargeable.

In addition, sensor system <NUM> can cause an alarm, such as an audible beep, based on a threshold level of bodily exudate being detected. Accordingly, sensor system <NUM> can include a speaker or other audio output device. Sensor system <NUM> can also cause a transmission of an alert to another device, for example, operated by a caretaker. Sensor system <NUM> can include a transmitter or transceiver capable of transmitting a radio signal to an external device. A color sensing application operating on a microcontroller installed within wearable sensor enclosure <NUM> can also log events, such as when bodily exudate is detected, to memory. Wearable sensor enclosure <NUM> can transmit measurements to an external device such as to a mobile phone operated by a caregiver.

Sensor system <NUM> can include a switch to activate or deactivate the sensor system <NUM>. The switch can be any suitable switch, such as a momentary switch or on/off switch. The switch can cause power to be connected from the battery <NUM> to the electronic devices in sensor system <NUM> and the color detector cell <NUM>. Alternatively, the switch can provide an input to processor <NUM> to cause processor <NUM> to take an action. Sensor system <NUM> can include one or more electrical connectors, which can be used to debug the sensor system <NUM>, calibrate the sensor system <NUM>, reset the sensor system <NUM> to factory settings, upgrade software on the sensor system <NUM>, etc..

In an aspect, sensor system <NUM> can also include a temperature sensor, which can detect heat from substances such as bodily exudate. In conjunction with data obtained from color detector cell <NUM>, the temperature sensor can provide additional information such as a temporary increase in temperature to microcontroller <NUM>. In another aspect, sensor system <NUM> can also include a humidity sensor, which can detect the presence of humidity, e.g., from bodily exudate. In conjunction with data obtained from color detector cell <NUM>, the humidity sensor can provide additional information such as a notification of a temporary increase in humidity to microcontroller <NUM>.

<FIG> depicts an embodiment of a wearable sensor enclosure that is configured to house electronic devices in accordance with an aspect of the present disclosure. <FIG> depicts wearable sensor housing <NUM>, which includes distal component <NUM>, proximal component <NUM>, circuit board <NUM>, and circuit board backing <NUM>.

An example of color detector cell is color detector cell <NUM>. An example of light source is LED <NUM>. Electronic devices <NUM> can include any suitable electronic devices for sensing such as processor <NUM>, microcontroller <NUM>, etc. Circuit board <NUM> can be inserted directly into distal component <NUM>.

Circuit board backing <NUM> can provide support to circuit board <NUM>. In some cases, circuit board backing <NUM> can have a translucent portion or one or more openings <NUM> and <NUM> to allow light to pass through. Openings <NUM>-<NUM> can line up with a color detector cell and/or a light source located on circuit board <NUM>, and with openings <NUM>-<NUM> located on proximal component <NUM>.

Distal component <NUM> can include an exterior button (not depicted) that can be configured to receive input from a user such as a mechanical push. The exterior button can be an area of over-molded elastomer without rigid lower support. A push translates into movement. In turn, the movement causes pressure to be applied to button <NUM>, which can cause one or more operations to be performed by electronic devices <NUM> such as activating or deactivating sensors, etc. In this manner, force from a user's finger translates to button <NUM>. Button <NUM> can any mechanical device that causes electrical contacts to be formed and/or broken such as a push-button switch, on-off switch, etc..

Distal component <NUM> can be made of a rigid material or a combination of rigid material and an elastomer. Wearable sensor housing <NUM> can include joints or seams between components can be sealed with an adhesive or otherwise molded together. For example, a weld located between the distal component <NUM> and the proximal component can ensure that liquids do not easily enter wearable sensor housing <NUM>. For example, this weld can result in a watertight factory seal. Batteries or other power devices may be single use, such that the end user does not need to replace batteries. Instead, the batteries or other power devices are sealed into the device.

In another aspect, the wearable sensor housing <NUM> includes an interior sensor enclosure. The interior sensor enclosure can include one or more openings to allow light to pass through, such as for a photodetector or from a LED. When present, these openings can be configured to line up with openings <NUM>-<NUM> and openings <NUM>-<NUM>. The interior sensor enclosure can be fabricated with a rigid material, for example, to better protect any electronic devices or sensors that are present within.

<FIG> depicts an aspect of a wearable sensor enclosure with a modified inner portion to facilitate interactions and an indicator light, in accordance with an aspect of the present disclosure. <FIG> includes wearable sensor enclosure <NUM>. Wearable sensor enclosure <NUM> includes button area <NUM> and circuit board <NUM>.

Circuit board <NUM> includes button <NUM> and LED <NUM>. As shown, and as described with respect to <FIG>, pressing button area <NUM> causes button <NUM> to be activated. Additionally or alternatively, LED <NUM> can output light through the surface of wearable sensor enclosure <NUM>. In this manner, a user can receive feedback, for example, whether the sensor is operating correctly. LED <NUM> can emit light of any color, e.g., white, blue, yellow, red, or green. Additionally, LED <NUM> can be configured to emit a different color of light based on a status. Examples of status include correct operation, incorrect operation, correct alignment, incorrect alignment, and low battery.

<FIG> depicts a top view of the wearable sensor enclosure of <FIG>. <FIG> shows a wearable sensor enclosure <NUM> that has a cutout portion <NUM>. Cutout portion <NUM> can be an area of a more rigid material that is removed. A more flexible material may be placed on or under cutout portion <NUM>. The more flexible material is illustrated in <FIG> by diagonal hashmarks. Providing this more flexible material can permit operation of a button (e.g., button area <NUM>), while maintaining an otherwise rigid structure.

For example, wearable sensor enclosure <NUM> may be made of a rigid material. A second part of material covering cutout portion <NUM> may be manufactured of an elastomeric material. In this way, certain parts of the wearable sensor enclosure <NUM> can be flexible. Additionally, use of an elastomer can avoid a need for separate sealing methods to prevent water or liquids from easily entering the wearable sensor enclosure.
