Description
TECHNICAL FIELD

The present disclosure generally relates to bedding and measuring apparatus for measuring air flow through bedding. More particularly an apparatus for measuring air flow through a pillow. Methods of use are included.


BACKGROUND

Sleep is critical for people to feel and perform their best, in every aspect of their lives. Sleep is an essential path to better health and reaching personal goals. Indeed, sleep affects everything from the ability to commit new information to memory to weight gain. It is therefore essential for people to use bedding that suit both their personal sleep preference and body type in order to achieve comfortable, restful sleep.


Studies have shown that sleeping on a surface with restricted air flow causing heat and moisture retention is not conducive for restful sleep. Moreover, these studies have shown that sleeping on a surface, after a long time, that increases moisture and uncomfortable temperature levels can cause or trigger illnesses such as, for example, migraines, Alzheimer's disease, glaucoma, sleep apnea, stroke, impotency, and similar illnesses. Finding the right sleeping surface, for example pillow, having good airflow is important for establishing good sleeping conditions. Testing the air flow of a pillow is essential in choosing the correct pillow for the individual to provide the best sleeping conditions. This disclosure describes a simple easy to use testing/display to show the airflow through a bedding surface, for example a pillow, relative to another surface.

DETAILED DESCRIPTION

The present disclosure may be understood more readily by reference to the following detailed description of the disclosure taken in connection with the accompanying drawing figures, which form a part of this disclosure. It is to be understood that this disclosure is not limited to the specific devices, methods, conditions or parameters described and/or shown herein, and that the terminology used herein is for the purpose of describing particular embodiments by way of example only and is not intended to be limiting of the claimed disclosure.


Also, as used in the specification and including the appended claims, the singular forms “a,” “an,” and “the” include the plural, and reference to a particular numerical value includes at least that particular value, unless the context clearly dictates otherwise. Ranges may be expressed herein as from “about” or “approximately” one particular value and/or to “about” or “approximately” another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another embodiment. It is also understood that all spatial references, such as, for example, horizontal, vertical, top, upper, lower, bottom, left and right, are for illustrative purposes only and can be varied within the scope of the disclosure. For example, the references “upper” and “lower” are relative and used only in the context to the other, and are not necessarily “superior” and “inferior.”


Reference will now be made in detail to the exemplary embodiments of the present disclosure, which are illustrated in the accompanying figures. Turning to FIGS. 1-15, there are illustrated components of a bedding marketing system 20.


In one embodiment, in accordance with the principles of the present disclosure, device 05 includes a front side 35, a backside 40, a right side 25, a left side 30, a top 10 and a bottom side 20 configured to construct a box-like structure having 4 sides a top and bottom. The box-like structure having an internal chamber. The top 10 of device 05 comprises and opening that is in direct communication with the internal chamber. The opening can have a grate-like structure configured to freely allow air in and out of the cavity while keeping items from entering into the chamber. In some embodiments, top surface 10 has indicia 50 embossed on the surface providing directions on where to place the article of bedding, for example a pillow, to be tested. Additional indicia can also be written on the top surface.


As shown in FIG. 1, the 4 sides (25, 30, 35 and 40), top 10 and bottom 20 each include a body 28 defining a chamber and an opening 15 cut into top surface 10 that is in communication with the chamber of device 05. At least one air flow generator 60 is positioned either within the chamber or is external to the chamber and is connected by a conduit 45. In some embodiments, at least one of air flow generators 60 is a fan having a motor, a shaft extending from motor and a blade that is fixed to a shaft. The motor is configured to rotate the shaft in a first direction, such as, for example, clockwise and/or a second directions, such as counterclockwise. The direction of rotation of the shaft determines whether a positive air is pushed into the chamber and out the opening of the top surface 10 or a negative pressure is realized pulling air into the opening. In some embodiments, the device 05 has a uniform diameter along the entire length of device 05. In some embodiments, the device 05 and/or opening 15 may have various cross section configurations, such as, for example, circular, oval, oblong, triangular, rectangular, square, polygonal, irregular, uniform, non-uniform, variable, tubular and/or tapered.


In some embodiments, device 05 includes a cover 18 positioned over a majority of opening 15 on the top surface 10 of device 05. The cover 18 is configured to allow air to travel in and out of the chamber while preventing larger items, such as, a pillow (55,155, 255) form being sucked into the chamber while the pillow is being tested. The cover 18 covering opening 15 allows air flow created by air flow generator 60 to pass through the cover 18 and into the pillow placed on the cover. In some embodiments, the cover can be removed and interchanged with different and/or replacement. In some embodiments, a pillow is positioned such that an outer surface of pillow is flush with an outer surface of the cover 15, as shown in FIG. 3.


User interfaces can be electrically coupled to air flow generator 60 by a wire, wirelessly, or controlled using a downloadable app. The air flow generator 60 when turned on causes rotation of the shaft to create air flow. In some embodiments, the shaft rotates in a clockwise direction generating a positive flow of air through the cover. When the shaft in the airflow generator is reversed air is pulled into chamber causing a suction of some degree between the pillow placed on the cover. If the pillow is configured has air flow the air will flow from the opening, through the pillow and felt on the opposite side of the pillow. The greater the air permeability of the pillow the more air felt through the pillow.


In some embodiments, the rotation of the shaft can be reversed and air drawn through the pillow into the chamber. Pillows that have a greater air flow will often retain its shape as air is sucked into the pillow, as shown in FIG. 3, unit 2. For pillows that have little or no air flow, the pillow can deform and be sucked against the cover 18 on the top surface 10 of the device 05 as shown in FIG. 3, unit 1. In some embodiments, air flow created by each of air flow generator 60 has the same velocity. In some embodiments, air flow created by air flow generators 60 moves through each of pillows (55,155, 255) at a different velocity. This can be used to show the amount of air flow through a pillow so as to maintain its shape.


In some embodiments, top surface 10 of device 05 comprises indicia 50 relating providing instructions on where to place the pillow to be tested. In some embodiments, indicia 50 is printed on a portion of device 05, such as, for example, on front side 35. In some embodiments, device 05 can have a display associated with it or incorporated into device 05, such as, for example, a display of an electrical device, such as, for example, a computer, tablet, smartphone, personal digital assistant. In some embodiments, the display that includes indicia 50 is a touchscreen. In such embodiments, the display that includes indicia 50 may be interactive such that the user can touch an icon on the touchscreen or a portion of the touchscreen to display a menu of options and/or navigate through a series of questions that will assist the user in selecting bedding material, for example. In some embodiments, the display that includes indicia 50 is not a touchscreen. In such embodiments, the display that includes indicia 50 is intended only to provide information and is not capable of changing in response to user input and/or action. In some embodiments, indicia 50 includes letters, words, characters and/or symbols that are printed on the top surface 10 or front side 35 and a display (not shown) that is incorporated into system 05. In some embodiments, indicia 50 includes a velocity at which air flows through the pillow and/or a numerical rating that corresponds to a velocity at which air flows through at least one of pillows being tested.



FIG. 2 shows a system comprising unit 1 and unit 2 that is configured to test 2 different pillows simultaneously to sow the affect on air being drawn into the chamber as shown in FIG. 3. Unit 1 of FIG. 3 shows a pillow having little to no air that passes through the pillow causing it to be deformed and sucked against the cover. This can be visually or numerically compared to the pillow placed on the top surface of unit 2. Here the pillow maintains its originally shape thereby indicating that the pillow has air flow and the air being drawn into the chamber goes through the pillow allowing it to roughly maintain its original shape.



FIG. 4 shows a device 500 having two separate units each having its own opening (515 and 515A) that is continuous with the chamber of unit 1 and the chamber of unit 2, respectively. The single unit separates the two chambers by a septum 545 positioned midway between the left side 530 and the right side 530A. Unit 1 and unit 2 are each equipped with their own air generators (540 and 540A) that are in fluid communication with unit 1 and unit 2 respectfully. This allows the testing of two separate pillows simultaneously to show the differ air flows side by side. Although two separate chambers are provided the device can also test pillows one at a time since each unit work independently. In some embodiments one air generator can be used to generate the airflow in device 500 thereby testing 2 pillows at one time with the activation of one air generator.


In operation and use, a user that is in the market for bedding, for example a pillow, may use the devices presented in this application to compare which pillow has the airflow characteristics that matches the users profile. The user may read indicia or the display provided to learn about different types of materials that are used to make bedding products, for example different pillows, and the role that airflow plays in selecting the correct pillow.


The user may then engage a feature on one or more of user interfaces to move one or more air flow generators from the off position to the on position. In particular, the user will place a pillow to be tested on the top surface of the device over the opening as directed by indicia (50,150 and 250). Once positioned, the air flow generator (60,140,540) that is associated with the first pillow to be tested is switched from the off position to the on position. This will allow the user to feel the amount of air that flows through the first pillow. In single unit device embodiments, the air generator is taken off of the testing surface and replaced with the next pillow to be tested. Once positioned the air generator is turned back on and its affect on the pillow is examined. that are one of sample materials 42.


In some embodiments in accordance with the principles of the present disclosure that have either two separate units (FIGS. 2 and 3) or one unit with two chambers (FIG. 4), a first pillow to be tested is positioned over the opening of unit 1 and a second pillow is positioned over the opening of unit 2. Once in position the air generator for each unit is turned on and the air flow of the pillows is examined. As stated above, the more restrictive the pillow is to air flow the more the pillow will deform because of the pillow being sucked into the chamber. In embodiments that have one air generator that supplies air to both chambers, that air generator is activated once the pillow are positioned to be tested. The affects of the air flow on the pillows can either be observed visually or be measured and displayed for the buyer to choose the correct pillow.


This may be repeated with additional pillows. The user may then compare the amount of air that moves through the pillows that were tested to determine which pillow they think would be best suited to their body type, body temperature, sleep position, etc. For example, if the user has a body type wherein he or she feels warm or hot when he or she is sleeping, the user may opt to select a pillow that provides the most amount of ventilation and/or provides more ventilation than at least another one of the pillows tested. In some embodiments, one or a plurality of articles of bedding, such as, for example, one or more bed sheets, blankets, and/or mattress toppers.


In some embodiments, information provided may guide a user in using the testing device so as to select pillows that best suits the user. For example, in some embodiments, indicia may include printed instructions for using devices described above to select pillows that best suits the user. In some embodiments, the information provided may be interactive and provides the user with questions or prompts that the user can answer or select to help the user select pillows that best suits the user. In some embodiments, a display is provided that may include an electronic device, such as, for example, a touchscreen that presents a question to the user when the user approaches the device. For example, the display/touchscreen may ask the user visually and/or audibly whether the user has a high body temperature, a low body temperature, or a moderate body temperature. The user can answer the question by touching the display/touchscreen and/or speaking. For example, the user may touch a portion of the display/touchscreen that includes information about people with high body temperatures or includes language such as “high body temperature.” In response the display will provide one or a plurality of sample pillows that are best adapted for people with high body temperatures. The display may also suggest sheets, mattress toppers and even mattresses that are consistent with the user information provided.


The user may then test pillows that are best adapted for people with high body temperatures in the manner discussed above. This will allow the user to see and feel the amount of air that flows through the pillows selected compare the amount of air that moves through the pillows that were tested to determine which of the pillows tested they think would be best suited for them. The user may then select an article of bedding and test it as described above to make a bedding selection that best fits the users profile.

In some embodiments, cart 600 includes a plurality of spaced apart wire dividers 668. Pillows 660, 662, 664, 666 are each configured for positioning between adjacent dividers 668 to maintain pillows 660, 662, 664, 666 in a vertical orientation within cavity 658. In some embodiments, threaded distal ends of dividers 668 extend through a thickness of wall 628 and are secured to wall 628 by threading nuts onto the threaded distal ends of dividers 668. In some embodiments, at least one of pillows 656, 660, 662, 664, 666 are the same or similar to one of the pillows disclosed in U.S. Pat. No. 8,646,134, which is expressly incorporated herein by reference, in its entirety.


In some embodiments, cart 600 is configured to be fixed to a surface, such as, for example a floor of a building. In such embodiments, one or more of rails 608, 614, 618, 622 may include one or a plurality of holes that extend through thicknesses of rails 608, 614, 618, 622 such that bolts or other fastening devices can be inserted through the holes in rails 608, 614, 618, 622 such that the bolts extend into the floor to fix cart 600 relative to the floor. In some embodiments, cart 600 is configured to be movable and includes casters 670 that are coupled to distal ends of each of rails 610, 612, 616, 620, as shown in FIGS. 6 and 7. In some embodiments, cart 600 is configured to be movable and includes a first pair of casters 670 that are positioned between rails 610, 616 as shown in FIGS. 5 and 8-10, and a second pair of casters 670 that are positioned between rails 612, 620.


Portion 602 includes a panel, such as, for example, a top wall 672 that extends from rail 636 to rail 638 and from rail 634 to rail 640. In some embodiments, wall 672 is coupled to rails 634, 636, 638, 640 such that a top surface 672a of wall 672 is flush with top surfaces 634a, 636a, 638a, 640a of rails 634, 636, 638, 640 to provide a surface suitable for supporting one or more of pillows 656, 660, 662, 664, 666, as discussed herein. Wall 672 has a solid configuration that is free of any holes, gaps, apertures, etc. that extend through a thickness of wall 672 such that wall 672 prevents air and/or moisture from moving through the thickness of wall 672. That is, air and/or moisture adjacent to surface 672a of wall 672 is prevented from moving through an opposite bottom surface 672b of wall 672. Wall 672 defines an opening 674 extending continuously through surface 672a and surface 672b such that opening 674 extends through the thickness of wall 672. A grate 676 is positioned in opening 674. In some embodiments, grate 676 is positioned in opening 674 such that a top surface 676a of grate 676 is flush with surface 672a and an opposite bottom surface 676b of grate 676 is flush with surface 672b, as shown in FIGS. 5 and 6, for example. Grate 676 includes a plurality of spaced apart holes 678 that each extend through a thickness of grate 676 defined by the distance between surface 676a and surface 676b. In some embodiments, opening 674 and/or grate 675 may be variously shaped, such as, for example, circular, oval, oblong, triangular, square, rectangular, polygonal, irregular, uniform, non-uniform, offset, staggered, undulating, arcuate, variable and/or tapered. In some embodiments, holes 678 may have various cross section configurations, such as, for example, circular, oval, oblong, triangular, rectangular, square, polygonal, irregular, uniform, non-uniform, variable and/or tapered.


Inner surfaces of panels 642, 650, 652 and surface 672b define an interior chamber 680, as best shown in FIGS. 6 and 7, for example. Chamber 680 is spaced apart from cavity 658 such that cavity 658 is not in communication with chamber 680. In some embodiments, the panels and/or rails that define chamber 680 are free of any free of any holes, gaps, apertures, etc. such that the only openings in cart 600 that are in communication with chamber 680 are holes 678. That is, the only place air and/or moisture within chamber 680 can exit chamber 680 is through holes 678. Likewise, the only place air and/or moisture outside of chamber 680 can enter chamber 680 is through holes 678.


An air flow generator 682 is positioned within chamber 680, as best shown in FIGS. 6 and 7, for example. In some embodiments, air flow generator 682 is configured to generate negative pressure to draw air and/or moisture A through a test article, such as, for example, one of pillows 656, 660, 662, 664, 666 and holes 678 and into chamber 680, as shown in FIGS. 6 and 7. In some embodiments, air flow generator 682 is positioned directly below grate 676 such that air flow generator 682 is coaxial with grate 676. In some embodiments, air flow generator 682 is positioned directly below grate 676 such that at least a portion of air flow generator 682 is coaxial with at least one of holes 678. It is envisioned that air flow generator 682 may also be positioned outside of chamber 680 and is connected to cart 600 by a conduit, such as, for example, conduit 45 that is in communication with chamber 680. In some embodiments, air flow generator 682 is a fan. In some embodiments, air flow generator 682 is an air pump.


Cart 600 includes one or a plurality of sensors, such as, for example, one or a plurality of pressure sensors 684 that are configured to measure the pressure imposed by air and/or moisture A as air and/or moisture A moves through one of pillows 656, 660, 662, 664, 666 by generating a signal as a function of the pressure imposed, for example. Sensor 684 is configured to generate a pressure value (in pounds per square inch, for example) corresponding to the pressure imposed by air and/or moisture A as air and/or moisture A moves through one of pillows 656, 660, 662, 664, 666. In one embodiment, sensor 684 is positioned between surfaces 676a, 676b such that sensor 684 is oriented within a thickness of grate 676 and extends across at least one of holes 678, as shown in FIG. 6. This allows sensor 684 to measure the pressure imposed by air and/or moisture A as air and/or moisture A moves through one of pillows 656, 660, 662, 664, 666.


A reader, such as, for example, a processor 686 is in communication with sensor 684 and is configured to convert the pressure value generated by sensor 684 to an air flow value (in cubic feet per minute, for example). In some embodiments, processor 686 converts the pressure value generated by sensor 684 to the air flow value using an algorithm. In some embodiments, processor 686 converts the pressure value generated by sensor 684 to the air flow value using a correlation curve created by correlating known air flow values to pressure values. In some embodiments, processor 686 is wired directly to sensor 684. In some embodiments, processor 686 is in wireless communication with sensor 684. In some embodiments, processor 686 is positioned outside of chamber 680, as shown in FIG. 6. In some embodiments, processor 686 is positioned within chamber 680, as shown in FIG. 7. In some embodiments, processor 686 is part of a computer, tablet, laptop, smart phone, etc. that is separate from cart 600. Processor 686 is in wired or wireless communication with a display, such as, for example, display 688 to provide a visual representation of the air flow value determined by processor 686. In some embodiments, display 688 is coupled directly to cart. In some embodiments, display 688 is part of a computer, tablet, laptop, smart phone, etc. that is separate from cart 600.


In one embodiment, sensor 684 is positioned between grate 676 and air flow generator 682 such that sensor 684 is spaced apart from both grate 676 and air flow generator 682, as shown in FIG. 7. Sensor 684 is connected to panel 652 by a bracket 690 and is connected to panel 642 by a bracket 692. This allows sensor 684 to be positioned directly above air flow generator 682 such that sensor 684 is coaxial with air flow generator 682 to allow sensor 684 to measure the pressure imposed by air and/or moisture A as air and/or moisture A moves through one of pillows 656, 660, 662, 664, 666 and into chamber 680 through holes 678.


In some embodiments, air flow generator 682 is configured to generate positive pressure to direct air and/or moisture B within chamber 680 through holes 678 and a test article, such as, for example, one of pillows 656, 660, 662, 664, 666, as shown in FIGS. 11 and 12. In one embodiment, cart 600 includes a first strap 694 and a second strap 696 that is configured to removably engage strap 694 to secure one of pillows 656, 660, 662, 664, 666 to cart 600, as shown in FIG. 11. Sensor 684 is coupled to one of straps 694, 696 to allow sensor 684 to measure the pressure imposed by air and/or moisture B as air and/or moisture B moves through one of pillows 656, 660, 662, 664, 666. In some embodiments, strap 696 can be coupled to strap 694 by Velcro, threads, mutual grooves, screws, adhesive, nails, barbs, raised elements, spikes, clips, snaps, friction fittings, compressive fittings, expanding rivets, staples, fixation plates, key/keyslot, tongue in groove, dovetail, magnetic connection and/or posts.


In one embodiment, cart 600 includes an arm 698 that extends over grate 676, as shown in FIG. 12. Sensor 684 is coupled to arm 698 such that sensor 684 is positioned over one of pillows 656, 660, 662, 664, 666 to allow sensor 684 to measure the pressure imposed by air and/or moisture B as air and/or moisture B moves through one of pillows 656, 660, 662, 664, 666. In some embodiments, arm 698 is permanently fixed to cart 600 such that arm 698 cannot be removed from cart 600 without breaking arm 698 and/or cart 600. In some embodiments, arm 698 is rotatable relative to cart 600 to allow the position of sensor 684 relative to grate 676 to be adjusted. For example, arm 698 may be rotatable relative to cart 600 to rotate arm 698 from an orientation in which sensor 684 is offset from grate 676 to an orientation in which sensor 684 is positioned directly over and/or is coaxial with grate 676. In some embodiments, arm 698 is configured to translate axially relative to cart 600 to adjust the distance between grate 676 and arm 698 to accommodate test articles having different thicknesses. For example, when a thick test article is being tested, arm 698 may be translated axially relative to grate 676 to increase the distance between grate 676 and arm 698 to accommodate positioning of the thicker test article between grate 676 and arm 698.


In operation and use, a first test article, such as, for example, one of pillows 656, 660, 662, 664, 666 is positioned on wall 672 such that the first test article covers at least a portion of grate 676. Air flow generator 682 is moved from an off position to an on position such that air flow generator 682 creates negative pressure that draws air and/or moisture A through the first test article and holes 678 and into chamber 680. Sensor 684 measures the pressure imposed by air and/or moisture A as air and/or moisture A moves through the first test article. Sensor 684 sends a signal to processor 686 representative of a pressure value (in pounds per square inch, for example) measured by sensor 684. Processor 686 converts the pressure value into to an air flow value (in cubic feet per minute, for example). Processor 686 then communicates with display 688 to provide a graphical representation of the air flow value on display 688. For example, in one embodiment, the air flow value is shown on display 688 using numbers and/or letters (10.0 cubic feet per minute (cfm)). In one embodiment, the air flow value is shown on display 688 using colors wherein different colors represent different air flow values. In one embodiment, the air flow value is shown on display 688 on a scale, such as, for example, a scale of one to ten, wherein numbers of the scale represent different air flow values. Display 688 thus provides a graphical representation of the air flow value associated with the first test article.


In some embodiments, air flow generator is moved from the on position to the off position and the test article is removed from cart 600. A second test article, such as, for example, another one of pillows 656, 660, 662, 664, 666 is positioned on wall 672 such that the second test article covers at least a portion of grate 676. Air flow generator 682 is moved from the off position to the on position such that air flow generator 682 creates negative pressure that draws air and/or moisture A through the second test article and holes 678 and into chamber 680. Sensor 684 measures the pressure imposed by air and/or moisture A as air and/or moisture A moves through the second test article. Sensor 684 sends a signal to processor 686 representative of a pressure value (in pounds per square inch, for example) measured by sensor 684 for the second test article. Processor 686 converts the pressure value for the second test article into to an air flow value (in cubic feet per minute, for example) for the second test article. Processor 686 then communicates with display 688 to provide a graphical representation of the air flow value for the second test article on display 688. In some embodiments, display 688 simultaneously displays the air flow value associated with the first test article and the air flow value associated with the second test article so that a tester may compare the two air flow values. The tester may select for purchase the test article having the air flow value that is closest to a desired air flow value. For example, if the tester desires a pillow that permits a high amount of air flow through the pillow to provide a cool sleeping surface, the tester may select for purchase the test article having the higher air flow value.


In some embodiments, the tester may test one or a plurality of test articles in addition to the first test article and the second test article, in the same manner the first and second test articles were tested. Display 688 may be configured to simultaneously displays the air flow value associated with the first test article, the air flow value associated with the second test article, and the air flow value(s) associated with any additional test articles so that a tester may compare the air flow values of the various test articles. The tester may select for purchase the test article having the air flow value that is closest to a desired air flow value.


In some embodiments, a first test article, such as, for example, one of pillows 656, 660, 662, 664, 666 is positioned on wall 672 such that the first test article covers at least a portion of grate 676. Air flow generator 682 is moved from an off position to an on position such that air flow generator 682 creates positive pressure that moves air and/or moisture B within chamber 670 through holes 678 and the first test article. Sensor 684 measures the pressure imposed by air and/or moisture B as air and/or moisture B moves through the first test article. Sensor 684 sends a signal to processor 686 representative of a pressure value (in pounds per square inch, for example) measured by sensor 684. Processor 686 converts the pressure value into to an air flow value (in cubic feet per minute, for example). Processor 686 then communicates with display 688 to provide a graphical representation of the air flow value on display 688.


In some embodiments, air flow generator is moved from the on position to the off position and the test article is removed from cart 600. A second test article, such as, for example, another one of pillows 656, 660, 662, 664, 666 is positioned on wall 672 such that the second test article covers at least a portion of grate 676. Air flow generator 682 is moved from the off position to the on position such that air flow generator 682 creates positive pressure that moves air and/or moisture B in chamber 670 through holes 678 and the second test article. Sensor 684 measures the pressure imposed by air and/or moisture B as air and/or moisture B moves through the second test article. Sensor 684 sends a signal to processor 686 representative of a pressure value (in pounds per square inch, for example) measured by sensor 684 for the second test article. Processor 686 converts the pressure value for the second test article into to an air flow value (in cubic feet per minute, for example) for the second test article. Processor 686 then communicates with display 688 to provide a graphical representation of the air flow value for the second test article on display 688. In some embodiments, display 688 simultaneously displays the air flow value associated with the first test article and the air flow value associated with the second test article so that a tester may compare the two air flow values. The tester may select for purchase the test article having the air flow value that is closest to a desired air flow value.


In one embodiment, shown in FIGS. 13-15, cart 600 is configured to test two test articles, such as, for example, two of pillows 656, 660, 662, 664, 666 simultaneously. Accordingly, portion 602 includes a partition 700 that divides chamber 680 into a first chamber 680a and a second chamber 680b that is spaced apart from chamber 680a by partition such that chamber 680b is not in communication with chamber 680a, as best shown in FIGS. 14 and 15. Wall 672 includes openings 674a and 674b that are similar to opening 674. Opening 674a is spaced apart from opening 674b by a portion of wall 672, as best shown in FIG. 13. A first grate 676a, similar to grate 676 is positioned in opening 674a and a second grate 676b, similar to grate 676 is positioned in opening 674b. Grates 676a, 676b each include a plurality of spaced apart holes 678. Holes 678 of grate 676a are in communication with chamber 680a and holes 678 of grate 676b are in communication with chamber 680b. It is envisioned that cart 600 can include any number of grates 676. In some embodiments, the number of grates 676 included in cart 600 can correlate to the number of test articles to be tested. For example, if a tester desires to test three test articles simultaneously, cart 600 will include three spaced apart grates 676, each in communication with a different chamber 680. Likewise, if a tester desires to test four test articles simultaneously, cart 600 will include four spaced apart grates 676, each in communication with a different chamber 680.


In one embodiment, shown in FIG. 14, cart 600 includes a first sensor 684a, similar to sensor 684 positioned within a thickness of grate 676a such that sensor 684a extends across at least one of holes 678 of grate 676a and cart 600 includes a second sensor 684b, similar to sensor 684 positioned within a thickness of grate 676b such that sensor 684b extends across at least one of holes 678 of grate 676b. However, it is envisioned that sensors 684a, 684b may be variously positioned with respect to cart 600 in any manner that allows sensors 684a, 684b to be in communication with air and/or moisture that moves through a test article. For example, in one embodiment, shown in FIG. 15, cart 600 includes a first strap 694a and a second strap 696a that is configured to removably engage strap 694a to a test article to cart 600. Sensor 684a is coupled to one of straps 694a, 696a to allow sensor 684a to measure the pressure imposed by air and/or moisture as air and/or moisture moves through a test article positioned over grate 676a. Likewise, cart 600 includes a first strap 694b and a second strap 696b that is configured to removably engage strap 694b to a test article to cart 600. Sensor 684b is coupled to one of straps 694b, 696b to allow sensor 684b to measure the pressure imposed by air and/or moisture as air and/or moisture moves through a test article positioned over grate 676b. In some embodiments, strap 696a can be coupled to strap 694a and/or strap 696b can be coupled to strap 694b by Velcro, threads, mutual grooves, screws, adhesive, nails, barbs, raised elements, spikes, clips, snaps, friction fittings, compressive fittings, expanding rivets, staples, fixation plates, key/keyslot, tongue in groove, dovetail, magnetic connection and/or posts. However, it is envisioned that sensor 684a and/or sensor 684b may be mounted to cart 600 using brackets similar to brackets 690, 692 and/or using an arm similar to arm 698, depending upon the requirements of a particular application. It is envisioned that cart 600 can include any number of sensors 684. In some embodiments, the number of sensors 684 included in cart 600 can correlate to the number of test articles to be tested. For example, if a tester desires to test three test articles simultaneously, cart 600 will include three spaced apart sensors 684, each configured to measure the amount of air flow through a different test article. Likewise, if a tester desires to test four test articles simultaneously, cart 600 will include four spaced apart sensors 684, configured to measure the amount of air flow through a different test article.


Cart 600 includes a first air flow generator 682a positioned in chamber 680b and a second air flow generator 682b positioned in chamber 680a. Air flow generator 682a is positioned directly below grate 676a such that air flow generator 682a is coaxial with grate 676a and/or at least one of holes 678 in grate 676a. Air flow generator 682a is configured to create negative pressure to draw air and/or moisture C outside of chamber 680a through a test article, such as, for example, one of pillows 656, 660, 662, 664, 666 and into chamber 680a through holes 678 of grate 676a, as shown in FIG. 14 and/or create positive pressure to move air and/or moisture D within chamber 680a through holes 678 of grate 676a and one of pillows 656, 660, 662, 664, 666, as shown in FIG. 15. Likewise, air flow generator 682b is configured to create negative pressure to draw air and/or moisture E outside of chamber 680b through a test article, such as, for example, one of pillows 656, 660, 662, 664, 666 and into chamber 680b through holes 678 of grate 676b, as shown in FIG. 14 and/or create positive pressure to move air and/or moisture F within chamber 680b through holes 678 of grate 676b and one of pillows 656, 660, 662, 664, 666, as shown in FIG. 15. In some embodiments, air flow generator 682a is configured to create the same amount of negative and/or positive pressure as air flow generator 682b such that air flow generators 682a, 682b will each create the same amount of air flow when air flow generators 682a, 682b are in an on position. As such, air flow generators 682a, 682b will each provide the same amount of air flow through the same test article when air flow generators 682a, 682b are in the on position. It is envisioned that cart 600 can include any number of air flow generators 682. In some embodiments, the number of air flow generators 682 included in cart 600 can correlate to the number of test articles to be tested. For example, if a tester desires to test three test articles simultaneously, cart 600 will include three spaced apart air flow generators 682, each positioned in a different chamber 680. Likewise, if a tester desires to test four test articles simultaneously, cart 600 will include four spaced apart air flow generators 682, each positioned in a different chamber 680.


In operation and use, a first test article, such as, for example, one of pillows 656, 660, 662, 664, 666 is positioned on wall 672 such that the first test article covers at least a portion of grate 676a and a second test article, such as, for example, one of pillows 656, 660, 662, 664, 666 is positioned on wall 672 such that the first test article covers at least a portion of grate 676b. Air flow generator 682a is moved from an off position to an on position such that air flow generator 682a creates negative pressure that draws air and/or moisture C through the first test article and holes 678 in grate 676a and into chamber 680a. Sensor 684a measures the pressure imposed by air and/or moisture C as air and/or moisture C moves through the first test article. Sensor 684a sends a signal to processor 686 representative of a pressure value (in pounds per square inch, for example) measured by sensor 684a. Processor 686 converts the pressure value into to a first air flow value (in cubic feet per minute, for example). Processor 686 then communicates with display 688 to provide a graphical representation of the first air flow value on display 688. Air flow generator 682b is moved from an off position to an on position such that air flow generator 682b creates negative pressure that draws air and/or moisture E through the second test article and holes 678 in grate 676b and into chamber 680b. Sensor 684b measures the pressure imposed by air and/or moisture E as air and/or moisture E moves through the second test article. Sensor 684b sends a signal to processor 686 representative of a pressure value (in pounds per square inch, for example) measured by sensor 684b. Processor 686 converts the pressure value into to a second air flow value (in cubic feet per minute, for example). Processor 686 then communicates with display 688 to provide a graphical representation of the second air flow value on display 688. In some embodiments, the graphical representations of the first and second air flow values are shown on display 688 simultaneously to allow a tester to quickly see any differences between the first air flow value and the second air flow value. The tester may select for purchase the test article having the air flow value that is closest to a desired air flow value. For example, if the tester desires a pillow that permits a low amount of air flow through the pillow to provide a warm sleeping surface, the tester may select for purchase the test article having the lower air flow value. In some embodiments, the tester may test one or a plurality of test articles in addition to the first test article and the second test article, in the same manner the first and second test articles were tested.


In one embodiment, a first test article, such as, for example, one of pillows 656, 660, 662, 664, 666 is positioned on wall 672 such that the first test article covers at least a portion of grate 676a and a second test article, such as, for example, one of pillows 656, 660, 662, 664, 666 is positioned on wall 672 such that the first test article covers at least a portion of grate 676b. Air flow generator 682a is moved from an off position to an on position such that air flow generator 682a creates positive pressure that moves air and/or moisture D within chamber 680a through holes 678 in grate 676a and the first test article. Sensor 684a measures the pressure imposed by air and/or moisture D as air and/or moisture D moves through the first test article. Sensor 684a sends a signal to processor 686 representative of a pressure value (in pounds per square inch, for example) measured by sensor 684a. Processor 686 converts the pressure value into to a first air flow value (in cubic feet per minute, for example). Processor 686 then communicates with display 688 to provide a graphical representation of the first air flow value on display 688. Air flow generator 682b is moved from an off position to an on position such that air flow generator 682b creates positive pressure that moves air and/or moisture F through holes 678 in grate 676b and the second test article. Sensor 684b measures the pressure imposed by air and/or moisture F as air and/or moisture F moves through the second test article. Sensor 684b sends a signal to processor 686 representative of a pressure value (in pounds per square inch, for example) measured by sensor 684b. Processor 686 converts the pressure value into to a second air flow value (in cubic feet per minute, for example). Processor 686 then communicates with display 688 to provide a graphical representation of the second air flow value on display 688. In some embodiments, the graphical representations of the first and second air flow values are shown on display 688 simultaneously to allow a tester to quickly see any differences between the first air flow value and the second air flow value. In some embodiments, the tester may test one or a plurality of test articles in addition to the first test article and the second test article, in the same manner the first and second test articles were tested.
