DETAILED DESCRIPTION
[0015] This disclosure describes a sleep system including at least
one multi-zone mattress that can be used as part of a bed. The
mattress can comprise a plurality of zones each including one or
more fluid inflatable bladders. This disclosure further describes a
control system for controlling the pressure, and thus the perceived
firmness, within each zone of the multi-zone mattress used within a
sleep system.
[0016] The term "zone," as used herein, can refer to a specified
portion of the footprint of a mattress used by an occupant for
sleeping. The mattress can be configured so that each "zone"
corresponds, for example, to a particular area of the occupants
body, such as an upper zone configured to support the occupant's
head and upper torso, a middle zone configured to support an
occupant's lower torso (e.g., lumbar region), and an upper portion
of the occupant's legs, and a lower zone configured to support the
occupant's lower legs. Other zone configurations are also
contemplated.
[0017] Each "zone" can be configured to be adjustable in some way,
such as adjustable firmness, adjustable position, or adjustable
temperature. A "zone" having adjustable firmness can comprise one
or more fluid inflatable bladders that can be inflated or deflated
with an inflation fluid, such as air. If a particular zone
comprises a plurality of inflatable bladders, the inflatable
bladders of the zone can be adjacent and in close proximity to each
other to form a continuous or substantially continuous zone.
Inflation or deflation of the fluid can provide for control of the
pressure within the one or more inflatable bladders associated with
each zone.
[0018] The term "multi-zone" (e.g., as used in the phrase
"multi-zone mattress" or "multi-zone support surface assembly"), as
used herein, can refer to a mattress comprising a plurality of
zones, wherein at least one property (e.g., pressure, position, or
temperature) of at least one zone of the plurality of zones can be
controlled independently of at least one other zone. In some
examples, each zone of the plurality of zones can be controlled
independently of all other zones of the plurality of zones. For
example, a multi-zone mattress can be configured so that the
firmness of each zone can be controlled independently of the
firmness of each other zone, e.g., by independently controlling the
pressure within the one or more inflatable bladders of each
zone.
[0019] The control system can include a controlling device, such as
a remote control, configured to control inflation and deflation the
inflatable bladders within each zone of the multi-zone mattress.
The controlling device can also include a display configured to
provide information to a user about the fluid pressure, and thus
the perceived firmness, within each zone of the multi-zone
mattress.
[0020] FIG. 1 shows a perspective view of an example sleep system
10. The sleep system 10 can include a bed 12 that is configured and
intended to be used by one or more occupants. In the example shown
in FIG. 1, the bed 12 is designed to be used by two occupants, a
first occupant 14 and a second occupant 16. In such a
configuration, the bed 12 can include one or more mattresses 18A,
18B (collectively referred to as "mattress 18" or "mattresses 18")
supported by a frame 19. The occupants 14, 16 can be supported by
the one or more mattresses 18. The bed 12 can include a first sleep
area 20 for the first occupant 14 and a second sleep area 22 for
the second occupant 16. In the case of a bed designed for a single
occupant, a single mattress 18 can be used. The one or more
mattresses 18 can comprise a pair of mattresses 18A, 18B, with a
first mattress 18A making up the first sleep area 20 and a second
mattress 18B making up the second sleep area 22. As described in
more detail below, each mattress 18 can be a multi-zone mattress
18, with the firmness (e.g., the pressure) of each zone being
independently controllable.
[0021] Each of the sleep areas 20, 22 can be movable or articulable
between a plurality of positions to provide the occupants 14, 16
with the ability to select a preferred position for comfort of for
a particular purpose. Each sleep area 20, 22 can include one or
more articulable sections. In an example, the first sleep area 20
can include a first head section 24 that can be raised and lowered
to adjust a position of the head or upper torso, or both, of the
first occupant 14 and a first leg section 26 that can be raised and
lowered to adjust a position of the legs or lower torso, or both,
of the first occupant 14. Similarly, the second sleep area 22 can
include a second head section 28 that can be raised and lowered to
adjust a position of the head or upper torso, or both, of the
second occupant 16 and a second leg section 30 that can be raised
and lowered to adjust a position of the legs or lower torso, or
both, of the second occupant 16.
[0022] As described in more detail below, each mattress 18 can
comprise a support surface assembly formed from a plurality of
fluid-inflatable bladders, e.g., air-inflatable bladders. The sleep
system 10 can further include one or more fluid filling sources 21,
23, such as a fluid pump, e.g., an air pump for air inflatable
bladders, which can feed pressurized fluid into the inflatable
bladders in order to inflate one or more inflatable bladders, or
can withdraw fluid from the inflatable bladders to assist in
deflating one or more inflatable bladders, or both. In the example
shown in FIG. 1, the sleep system 10 includes a first fluid pump 21
for inflating or deflating, or both, the inflatable bladders
associated with the first sleep area 20 and a second fluid pump 23
for inflating or deflating, or both, the inflatable bladders
associated with the second sleep area 22.
[0023] The sleep system 10 can also include a pair of user
controlling devices 32, 34 to allow each occupant 14, 16 to control
the operation of his or her respective sleep area 20, 22. As shown
in FIG. 1, the sleep system 10 can include a first user controlling
device 32, e.g., a first handheld remote control 32, that has been
configured to control operation of the first sleep area 20, and a
second user control device 34, e.g., a second handheld remote
control 34, that has been configured to control operation of the
second sleep area 22. The first occupant 14 can use the first
remote control 32 to control operation of the first sleep area 20,
upon which the first occupant 14 is positioned, and the second
occupant 16 can use the second remote control 34 to control
operation of the second sleep area 22 upon which the second
occupant 16 is positioned.
[0024] The sleep system 10 can include an articulation system for
controlling articulation of the articulable sections 24, 26, 28,
30. The articulation system can include a set of articulating
motors, with each articulable section being articulated by one or
more of the motors. For example, a first head motor 42 can be
configured to articulate the first head section 24 of the first
sleep area 20. A first leg motor 44 can be configured to articulate
the first leg section 26 of the first sleep area 20. A second head
motor 46 can be configured to articulate the second head section 28
of the second sleep area 22. And, a second leg motor 48 can be
configured to articulate the second leg section 30 of the second
sleep area 22. Examples of motors that can be used for the
articulating motors 42, 44, 46, 48 include, but are not limited to,
bed articulating motors manufactured by Leggett & Platt, Inc.,
Carthage, Mo., USA.
[0025] The sleep system 10 can also include one or more
controllers, such as a control box that includes the electronics
and hardware for providing instructions to the fluid pumps 21, 23
and the articulating motors 42, 44, 46, 48. FIG. 1 shows the
articulation system including a single, common controller 50 that
is configured to control both of the sleep areas 20, 22, e.g., both
of the fluid pumps 21, 23 and all of the articulating motors 42,
44, 46, 48. The articulation system can also include more than a
single common controller. For example, each sleep area 20, 22 can
have its own controller (not shown), such as a first controller
corresponding to the first sleep area 20 that is configured to
control the first fluid pump 21 and the articulating motors 42 and
44 and a second controller corresponding to the second sleep area
22 that is configured to control the second fluid pump 23 and the
articulating motors 46 and 48.
[0026] Each remote control 32, 34 can be in communication with the
one or more controllers 50, such as via a wireless communication
link 52, 54. The remote controls 32, 34 can send control signals to
the controller 50 via the communication links 52, 54, such as an
inflation control signal directed to a fluid pump 21, 23 or a
movement control signal directed to one or more articulable motor
42, 44, 46, 48.
[0027] An "inflation control signal," as used herein, can refer to
a signal or plurality of signals sent from a remote control 32, 34
to the controller 50 corresponding to a particular inflation
condition, such as a pressure setting within a particular
inflatable bladder. An inflation control signal can include one or
more instructions for a pressure or perceived firmness set point
for a particular inflatable bladder, for the action to be taken by
a particular fluid pump 21, 23, e.g., feeding the inflating fluid
into the bladder or withdrawal of the fluid from the bladder and
determining the pressure within the particular inflatable
bladder.
[0028] A "movement control signal," as used herein, can refer to a
signal or plurality of signals sent from a remote control 32, 34 to
the controller 50 corresponding to a particular movement or
position of one or more of the articulable sections 24, 26, 28, 30.
A movement control signal can include one or more instructions for
the direction of movement of a particular articulable section 24,
26, 28, 30, e.g., the direction of movement of a corresponding
articulating motor 42, 44, 46, 48, a speed for the movement of a
particular articulable section 24, 26, 28, 30 or of a particular
articulating motor 42, 44, 46, 48, or an overall position of the
corresponding sleep area 20, 22 being controlled by the remote
control 32, 34, such as a preset position.
[0029] The controller 50 can send one or more pump control signals
to the fluid pumps 21, 23 corresponding to a desired action to be
taken by the fluid pumps 21, 23. A "pump control signal," as used
herein, can refer to a signal or plurality of signals sent from a
controller, such as the controller 50, to one or more fluid pumps
21, 23, corresponding to a particular action to be taken by the
fluid pump 21, 23 (such as opening of an inlet valve into a
particular inflatable bladder and either feeding of fluid into the
bladder or withdrawing fluid from the bladder).
[0030] The controller 50 can also send one or more motor control
signals to the articulating motors 42, 44, 46, 48 corresponding to
a desired motion of the articulating motors 42, 44, 46, 48. A
"motor control signal," as used herein, can refer to a signal or
plurality of signals sent from a controller, such as the controller
50, to one or more articulating motors 42, 44, 46, 48,
corresponding to a particular movement or position of one or more
articulable sections 24, 26, 28, 30. A motor control signal or
signals can comprise an instruction for one or both of the
direction that the articulating motor 42, 44, 46, 48 should
articulate and the speed that the articulating motor 42, 44, 46, 48
should travel.
[0031] In an example, a plurality of communication cables 56 can
carry the motor control signals from the controller 50 to the
articulating motors 42, 44, 46, 48, e.g., with each cable 56
corresponding to a particular motor 42, 44, 46, 48.
[0032] Examples of inflatable beds that can be used with the
systems and methods of the present disclosure include, but are not
limited to, Sleep Number beds, sold by Select Comfort Corp.,
Minneapolis, Minn., USA. Examples of inflatable adjustable beds
that are similar to the articulable sleep areas described in the
present disclosure include, but are not limited to, Sleep Number
Split King or Split Queen beds, sold by Select Comfort Corp.
[0033] Although FIG. 1 is shown and described as including one or
more articulable sleep areas, the present disclosure is not so
limited, and the articulable sleep areas 20, 22 of FIG. 1 are
merely meant to be a non-limited example. In some examples, the
sleep areas 20, 22 can be non-articulable, or standard type sleep
areas, e.g., so that each sleep area 20, 22 remains in the same or
substantially the same position, such as a flat or substantially
flat position, throughout the use of the sleep system 10.
[0034] FIGS. 2-4 show an example support surface assembly 60 that
can be used in the example sleep system 10 of FIG. 1. For example,
the support surface assembly 60 can form a part of either of the
mattresses 18A, 18B of the bed 12. In an example, each sleep area
20, 22 can comprise a separate support surface assembly 60, and the
pair of support surface assemblies 60 can be joined together to
form a substantially uniform and substantially continuous support
surface. An example of structures and methods for joining a pair of
support surface assemblies 60 in a side-by-side arrangement is
described in U.S. Pat. No. 7,865,988, issued on Jan. 11, 2011,
assigned to the assignee of this application, the disclosure of
which is incorporated by reference herein in its entirety
[0035] The support surface assembly 60 can comprise a plurality of
inflatable bladders 62A, 62B, 62C (collectively "inflatable bladder
62" or "inflatable bladders 62"), such as one or more
fluid-inflatable bladders 62, for example one or more
air-inflatable bladders 62. The inflatable bladders 62 can be
arranged in a manner to form a support surface 64. The support
surface 64 can be a sleep surface upon which an occupant 14, 16 can
be supported, or the support surface 64 can support For example, a
top surface 66A of a first inflatable bladder 62A, a top surface
66B of a second inflatable bladder 62B, and a top surface 66C of a
third inflatable bladder 62C can be arranged in an end-to-end
manner so as to form a continuous or substantially continuous
support surface 64. In the example of FIGS. 2-4, the support
surface assembly 60 includes three inflatable bladders 62A, 62B,
62C. However, the support surface assembly 60 can include fewer or
more inflatable bladders 62. For example, as shown in FIG. 3, a
support surface assembly can include two inflatable bladders, or a
support surface assembly can include four or more inflatable
bladders.
[0036] Each inflatable bladder 62 can comprise a generally
rectangular prism shape defined by a top wall 68A, 68B, 68C
(collectively "top wall 68" or "top walls 68"), a bottom wall 70A,
70B, 70C (collectively "bottom wall 70" or "bottom walls 70"), a
side wall 72A, 72B, 72C (collectively "side wall 72" or "side walls
72") and side wall 74A, 74B, 74C (collectively "side wall 74" or
"side walls 74"), an end wall 76A, 76B, 76C (collectively "end wall
76" or "end walls 76"), and an end wall 78A, 78B, 78C (collectively
"end wall 78" or "end walls 78"). The inflatable bladders 62 can
have substantially the same dimensions or can have different
dimensions depending on the desired effect for the occupant 14, 16
lying on the support surface assembly 60.
[0037] As best shown in FIG. 2, the inflatable bladders 62 can be
arranged in a series end-to-end arrangement, e.g., with the second
end wall 78A of the first inflatable bladder 62A being adjacent to
the first end wall 76A of the second inflatable bladder 62B, and
the second end wall 78B of the second inflatable bladder 62B being
adjacent to the first end wall 76C of the third inflatable bladder
62C. In this way, the inflatable bladders 62 can be arranged in a
head-to-toe fashion, e.g., with the first inflatable bladder 62A
being adjacent to a head and upper torso of an occupant 14, 16, the
second inflatable bladder 62B being adjacent to the trunk or lumbar
area of an occupant 14, 16, and the third inflatable bladder 62C
being adjacent to the legs of the occupant 14, 16.
[0038] In an example, a thickness of each inflatable bladder 62 can
be from about 2.5 centimeters (cm) (about 1 inch) to about 25 cm
(about 10 inches). The walls 68, 70, 72, 74, 76, 78 of the
inflatable bladders 62 can comprise any material that can be useful
for an inflatable application, particularly with respect to
fluid-inflatable bladders for sleep systems. Examples of materials
that can be used for the walls inflatable bladders 62 include, but
are not limited to, cotton rubber materials, nylon,
polyvinylchloride, polyester, polyurethane, rayon vinyl, and
combinations thereof.
[0039] FIGS. 5 and 6 show non-limiting examples of different
configurations of support surface assemblies that can be used, for
example, in the sleep system of FIG. 1. Each example support
surface assembly includes two or more inflatable bladders, and each
inflatable bladder in the examples of FIGS. 5 and 6 can include
features of the inflatable bladders 62 described above with respect
to the support surface assembly 60 in FIGS. 2-4.
[0040] FIG. 5 shows a conceptual perspective view of a first
example multi-zone support surface assembly 80. The example support
surface assembly 80 includes two zones having different sizes, with
a first zone comprising a first inflatable bladder 82A and a second
zone comprising a second inflatable bladder 82B. The first
inflatable bladder 82A can be positioned generally at a head end of
the support surface assembly 80 such that the first inflatable
bladder 82A can support the head and upper torso of an occupant.
The first inflatable bladder 82A is, therefore, referred to herein
as a "head bladder 82A." The second inflatable bladder 82B can be
positioned longitudinally adjacent to the head bladder 82A, e.g.,
at a foot end of the support surface assembly 80 such that the
second inflatable bladder 82B can support the feet, legs, and
lumbar region of an occupant. The second inflatable bladder 82B is,
therefore, referred to herein as a "foot bladder 82B."
[0041] The head bladder 82A and the foot bladder 82B can be sized
for a desired effect. In an example, the head bladder 82A can be
sized so that at certain pressures, such as low pressures within
the bladder 82A, the shifting of an occupant during sleep, or the
shifting of the bladder 82A during articulation, will not
substantially affect the overall pressure in the head bladder 82A.
One factor that can determine the effect of shifting or
articulation is the overall volume of the head bladder 82A, which
can be changed by changing the overall length of the head bladder
82A.
[0042] As shown in the example of FIG. 5, the head bladder 82A and
the foot bladder 82B can be completely separate inflatable bladders
such that the adjacent bladders 82A, 82B are substantially free to
move with respect to one another, for example substantial freedom
to move in one or more of a longitudinal direction, in a lateral
direction, and in a vertical direction. The substantially free
movement of the head bladder 82A and the foot bladder 82B can allow
for better positioning of the bladders 82A, 82B with respect to
each other during movement of the bed or the occupant. The more
free movement can provide for advantages such as better alignment
of the occupants spine during sleep, particularly when the
inflatable bladders 82A, 82B are inflated to higher pressures. The
substantially free movement can also provide a more stable support
surface, such as by dampening wave-like movement of the support
surface assembly 80. The substantially free movement can also
provide for more cost-effective replacement or easier replacement
of inflatable bladders 102, or both. The substantially free
inflatable bladders 102 can also have better aesthetics, e.g., can
be more visually appealing. Alternatively, the inflatable bladders
82A, 82B can be configured similar to the inflatable bladders 92A,
92B, 92C of the support surface assembly 90 of FIG. 6, e.g., with a
flexible joint between the inflatable bladders 82A, 82B.
[0043] The bladders 82A, 82B can be inflatable and deflatable in
order to control the pressure within the bladders 82A, 82B, and
thus to control the perceived firmness of each zone of the support
surface assembly 80 as experienced by an occupant. In the case of
fluid-inflatable bladders 82A, 82B, one or more fluid inlet hoses
84A, 84B can be connected to each one of the inflatable bladders
82A, 82B. The connection of the inlet hoses 82A, 84B in FIG. 5 can
be referred to as a "parallel fluid communication," which, as used
herein, can refer to at least two inflatable bladders being
directly connected to an fluid filling source, rather than a single
fluid bladder being directly connected to the fluid filling source
and subsequent inflatable bladders being connected to an adjacent
inflatable bladder for its fluid filling source. The fluid inlet
hoses 84A, 84B can be connected to a fluid filling source, such one
of the fluid pumps 21, 23 shown in FIG. 1, that can feed
pressurized fluid into the inflatable bladders 82A, 82B in order to
inflate the inflatable bladders 82A, 82B or can withdraw fluid in
order to deflate the inflatable bladders 82A, 82B to provide a
desired pressure, and therefore a desired firmness for the
occupant.
[0044] As described in more detail below, each separate fluid inlet
hose 84A, 84B can also be controlled separately in order to provide
for independent control of the pressure, and thus the perceived
firmness, of each inflatable bladder 82A, 82B.
[0045] Each fluid inlet hose 84A, 84B can include a corresponding
valve 86A, 86B that can be positioned within the fluid inlet hose
84A, 84B or at a connection point between the fluid inlet hose 84A,
84B and a corresponding inflatable bladder 82A, 82B to control or
shut off fluid flow through the fluid inlet hoses 84A, 84B. Each
inflatable bladder 82A, 82B can also include a corresponding
bladder inlet valve 88A, 88B to prevent fluid from escaping an
inflatable bladder 82A, 82B if a corresponding fluid inlet hose
84A, 84B is disconnected from the inflatable bladder 82A, 82B. In
another example, the fluid inlet hoses 84A, 84B can be coupled
directly to the inflatable bladders 82A, 82B.
[0046] FIG. 6 shows a conceptual perspective view of a second
example multi-zone support surface assembly 90. The example support
surface assembly 90 includes three zones rather than the dual zones
of the support surface assembly 80 shown in FIG. 5. A first zone of
the support surface assembly 90 comprises a first inflatable
bladder 92A, a second zone comprises a second inflatable bladder
92B, and a third zone comprises a third inflatable bladder 92C. The
first inflatable bladder 92A can be positioned generally at a head
end of the support surface assembly 90 such that the first
inflatable bladder 92A can support the head and upper torso of an
occupant. The first inflatable bladder 92A is, therefore, referred
to herein as a "head bladder 92A." The second inflatable bladder
92B can be positioned longitudinally adjacent to the head bladder
92A and the third inflatable bladder 92C and can be sized so that
the second inflatable bladder 92B can support the lumbar region,
trunk/waist, and upper legs of an occupant. The second inflatable
bladder 92B is, therefore, referred to herein as a "lumbar bladder
92B." The third inflatable bladder 92C can be positioned
longitudinally adjacent to the lumbar bladder 92B so that the third
inflatable bladder can support the lower legs and feet of an
occupant. The third inflatable bladder 92C is, therefore, referred
to herein as a "foot bladder 92C."
[0047] Adjacent inflatable bladders 92A, 92B, 92C of the support
surface assembly 90 can be connected together with a flexible
joint, such as a first flexible joint 94 between the head bladder
92A and the lumbar bladder 92B, and a second flexible joint 96
between the lumbar bladder 92B and the foot bladder 92C. In an
example, the first flexible joint 94 can be formed by a common
sheet of material that spans across the head bladder 92A and the
lumbar bladder 92B, and the second flexible joint 96 can be formed
by a common sheet of material that spans across the lumbar bladder
92B and the foot bladder 92C. One or more of the flexible joints
94, 96 can be on the top of the support surface assembly 90, e.g.,
so that the inflatable bladders 92A, 92B, 92C can pivot generally
upward relative to one another at the flexible joints 94, 96.
Alternatively, one or more of the flexible joints 94, 96 can be on
the bottom of the support surface assembly 90, e.g., so that the
inflatable bladders 92A, 92B, 92C can pivot generally downward
relative to one another at the flexible joint 94, 96.
[0048] The location of each flexible joint 94, 96 can be selected
to be on the top or on the bottom of the support surface assembly
90 depending on the desired ease of pivoting in a particular
direction. For example, if the flexible joint 94 is to be located
over an articulable joint in an articulable sleep system that
articulates upward, such as the joint of the head sections 24, 28
in the sleep system 10 of FIG. 1, than the flexible joint 94 can be
located on the top of the support surface assembly 90, e.g., to
better permit the head bladder 92A to pivot upward relative to the
lumbar bladder 92B. Similarly, if the flexible joint 96 is to be
located over an articulable joint that articulates downward, such
as the joint of the leg sections 26, 30 in the sleep system 10 of
FIG. 1, then the flexible joint 96 can be located on the bottom of
the support surface assembly 90, e.g., to better permit the leg
bladder 92C to pivot downward relative to the lumbar bladder
92B.
[0049] In an example, the flexible joints 94, 96 can be formed in a
support surface 98 that is formed by the support surface assembly
90. For example, the top walls (similar to the top walls 68 of the
inflatable bladders 62 in FIGS. 2-4) of the head bladder 92A, the
lumbar bladder 92B, and the foot bladder 92C can both be formed by
a continuous sheet of material that spans across the entire length
of the support surface assembly 90. Alternatively, the continuous
sheet of material can be coupled with the top wall of the head
bladder 92A, the top wall of the lumbar bladder 92B, and the top
wall of the foot bladder 92C. Such a continuous sheet of material
can also be laid across the bottom walls of the inflatable bladders
92A, 92B, 92C to form the flexible joint 124 on a bottom side,
rather than the top side of the support surface assembly 90.
[0050] Each flexible joint 94, 96 can include one or more
releasable fasteners (not shown) that can allow the inflatable
bladders 92A, 92B, 92C to be disconnected and separated from one
another if needed. For example, the releasable fastener can
comprise a zipper between the head bladder 92A and the lumbar
bladder 92B (flexible joint 94) or between the lumbar bladder 92B
and the foot bladder 92C (flexible joint 96). Releasable fasteners
other than a zipper can be used, such as, but not limited to,
releasable clips, releasable clamps, or releasable hooks and
eyelets.
[0051] One or more releasable fasteners coupling the inflatable
bladders 92A, 92B, 92C can allow a damaged inflatable bladder to be
uncoupled from undamaged inflatable bladders to replace the damaged
inflatable bladder without having to replace the entire support
surface assembly, e.g., without having to replace the undamaged
inflatable bladder. For example, if during use, the foot bladder
92C becomes damaged, such as by being punctured or developing a
leak, while the head bladder 92A and the lumbar bladder 92B remains
undamaged, the one or more releasable fasteners can then be
disengaged to uncouple the damaged foot bladder 92C from the
undamaged bladders 92A, 92B. The damaged foot bladder 92C can then
be removed without having to replace the undamaged bladders 92A,
92B. A replacement foot bladder 92C can then be coupled to the
undamaged lumbar bladder 92B with the one or more releasable
fasteners.
[0052] FIGS. 5 and 6 show examples of support surface assemblies
80, 90 that can be used as part of a multi-zone mattress, for
example to be used as a mattress 18A, 18B in the sleep surface
assembly 10 shown in FIG. 1. As shown above, each zone of the
multi-zone support surface assemblies can comprise only a single
inflatable bladder, e.g., only the head bladder 82A for a first
zone and only the foot bladder 82B for a second zone of the support
surface assembly 80; or only the head bladder 92A for a first zone,
only the lumbar bladder 92B for a second zone, and only the foot
bladder 92B for a third zone of the support surface assembly 90).
However, the present disclosure is not limited to multi-zone
mattress or multi-zone support surface assemblies with zones
comprising only a single inflatable bladder. Rather, each zone can
include a plurality of inflatable bladders that are grouped
together or controlled together, or both, so that, to the occupant,
they seem to be a single unit. The number of inflatable bladders
selected for each zone can depend on design considerations, such as
ease of operation and the overall comfort of the occupant. Further
examples of multi-zone support surface assemblies and mattresses
are described in the co-pending patent application entitled
"MULTI-ZONE FLUID CHAMBER AND MATTRESS SYTEM," U.S. application
Ser. No. 13/828,985, filed on Mar. 14, 2013, assigned to the
assignee of this patent application, which is incorporated by
reference herein in its entirety.
[0053] FIG. 7 is a block diagram detailing an example of data
communication between certain components of the sleep system 10. As
described above with respect to FIG. 1, the sleep system 10 can
include one or more user controlling devices 32, 34, such as
handheld remote controls 32, 34, that can be in communication with
the controller 50 via a communication link 52, 54, such as a
wireless communication link 52, 54. The controller 50 is, in turn,
in electrical communication with the fluid pumps 21, 23 via cables
56.
[0054] In the example shown in FIG. 7, the sleep system 10 includes
a single fluid pump 21 that is configured for inflating or
deflating both the first mattress 18A and the second mattress 18B
(which each comprise a plurality of inflatable bladders (not shown
in FIG. 7)), such that the pump 21 can supply fluid, such as air,
to all of the inflatable bladders of the sleep system 10. The fluid
pump 21 can supply fluid to mattresses 18A, 18B through one or more
fluid tubes to cause increases and decreases in the fluid pressure
in the inflatable bladders of each of the mattresses 18A, 18B based
upon commands input by a user through the remote control 32, 34.
For example, one or more first fluid tubes 102A can feed the
inflating fluid, e.g., air, from the pump 21 to the first mattress
18A and one or more second fluid tubes 102B can feed the inflating
fluid, e.g., air, from the pump 21 to the second mattress 18B.
[0055] FIG. 7 shows only a single fluid tube 102A, 102B to each
mattress 18A, 18B. However, as described above with respect to
FIGS. 5 and 6, the mattresses 18A, 18B can comprise a plurality of
inflatable bladders that each have a separate fluid tube, such as
the fluid tubes 84A, 84B for inflating or deflating the inflatable
bladders 82A, 82B, respectively, of the example support surface
assembly 80 shown in FIG. 5 or the fluid tubes 94A, 94B, 94C for
inflating or deflating the inflatable bladders 92A, 92B, 92C,
respectively, of the example support surface assembly 90 shown in
FIG. 6.
[0056] The remote control 32, 34 can include a display 104 and one
or more controls, such as controls 106 and 108, which are
configured for control of the fluid dispensing system. The one or
more controls 106, 108 can include an output selecting control, a
pressure increase control, and a pressure decrease control. The
output selecting control can be configured to allow a user to
switch the output of the fluid pump 21 between the first mattress
18A and the second mattress 18B so that each remote control 32, 34
can be enabled control of multiple air chambers with a single
remote control 32, 34. The output selecting control can also be
configured to allow selection of a specific inflatable bladder that
makes up the selected mattress 18A, 18B. For example, if each
mattress 18A, 18B includes three inflatable bladders (similar to
the head bladder 92A, the lumbar bladder 92B, and the foot bladder
92C of the support surface assembly 90 shown in FIG. 6), the output
selecting control can allow a user to select which of the three
inflatable bladders is desired to be controlled.
[0057] The pressure increase and decrease controls can allow a user
to increase or decrease the pressure, respectively, in the selected
inflatable bladder selected with the output selecting means 28.
Adjusting the pressure within the selected inflatable bladder can
cause a corresponding adjustment to the firmness of the inflatable
bladder.
[0058] Each of the controls can be a physical control (e.g., switch
or button) or can be an input control displayed on the display 104,
such as via a series of menu prompts or a touch screen input
device. Separate remote controls 32, 34 can be provided for each
mattress 18A, 18B, as shown in FIG. 1.
[0059] As shown in FIG. 7, the controller 50 can include a power
supply 110, a processor 112, a memory 114, a switching means 116,
and an analog to digital (A/D) converter 118. The switching means
116 can be, for example, a relay or a solid state switch. The
switching means 116 can be located in the pump 21 rather than the
controller 50.
[0060] The pump 21 and the remote control 32, 34 can be in two-way
communication with the controller 50. The pump 21 can include a
motor 120, a pump manifold 122, a relief valve 124, one or more
first control valves 126A, one or more second control valves 126B,
and a pressure transducer 128. The pump 21 can be fluidly connected
with the first mattress 18A via the one or more first fluid tubes
102A and to the second mattress 18B via the one or more second
fluid tubes 102B.
[0061] The one or more first control valves 126A can be controlled
to regulate the flow of fluid between the pump 21 and the
inflatable bladders of the first mattress 18A, such as with each
control valve 126A controlling the flow to a corresponding fluid
tube 102A, which in turn is connected to a corresponding inflatable
bladder of the first mattress 18A. The one or more second control
valves 126B can be controlled to regulate the flow of fluid between
the pump 21 and the inflatable bladders of the second mattress 18B,
such as with each control valve 126B controlling the flow to a
corresponding fluid tube 102B, which in turn is connected to a
corresponding inflatable bladder of the second mattress 18B. The
one or more first control valves 126A and the one or more second
control valves 126B can be controlled by the switching means 116 to
control which control valve 126A, 126B is to be opened or closed
and by how much.
[0062] In an example, the pump 21 and the controller 50 can be
provided and packaged as a single unit. Alternatively, the pump 21
and the controller 50 can be provided as physically separate
units.
[0063] In operation, the power supply 110 of the controller 50 can
receive power, such as 110 VAC power, from an external source and
can convert the power to various forms required by certain
components of the air bed system 10. The processor 112 can control
various logic sequences associated with operation of the sleep
system 10.
[0064] The example sleep system 10 shown in FIG. 7 shows two
mattresses 18A, 18B and a single the pump 21. However, in an
example, a separate pump can be associated with each mattress 18A,
18B of the sleep system, for example as shown in FIG. 1. In another
example, the sleep system can include a pump for each inflatable
bladder, or for a subset of the plurality of inflatable bladders,
of the sleep system. Separate pumps can allow each inflatable
bladder or set of bladders to be inflated or deflated independently
and simultaneously. Furthermore, additional pressure transducers
can also be incorporated into the system such that, for example, a
separate pressure transducer can be associated with each inflatable
bladder.
[0065] In the event that the processor 112 sends a decrease
pressure command for one of the inflatable bladders, the switching
means 116 can be used to convert the low voltage command signals
sent by the processor 112 to higher operating voltages sufficient
to operate the relief valve 124 of pump 21 and open the
corresponding control valve 126A or 126B. Opening the relief valve
124 can allow air to escape from the desired inflatable bladder
through the corresponding fluid tubes 102A, 102B. During deflation,
the pressure transducer 128 can send pressure readings to the
processor 112 via the A/D converter 118. The A/D converter 118 can
receive analog information from the pressure transducer 128 and can
convert the analog information to digital information useable by
the processor 112. The processor 112 can send the digital signal to
the remote control 32, 34 to update the display 104 on the remote
control in order to convey pressure information regarding the
plurality of inflatable bladders to the user, as described in more
detail below.
[0066] In the event that the processor 112 sends an increase
pressure command, the pump motor 120 can be energized, sending air
to the designated air chamber through the corresponding fluid tube
48A or 48B via electronically operating the corresponding valve
126A, 126B. While air is being delivered to the particular
inflatable bladder in order to increase the firmness of the
particular inflatable bladder, the pressure transducer 128 can
sense pressure within the pump manifold 122. The pressure
transducer 128 can send pressure readings to the processor 112 via
the A/D converter 118. The processor 112 can use the information
received from the A/D converter 118 to determine the difference
between the actual pressure in the particular inflatable bladder
and the desired pressure. The processor 112 can send the digital
signal to the remote control 32, 34 to update the display 104 on
the remote control in order to convey pressure information to the
user.
[0067] During an inflation or deflation process, the pressure
sensed within the pump manifold 122 can provide an approximation of
the pressure within the inflatable bladder. An example method of
obtaining a pump manifold pressure reading that is substantially
equivalent to the actual pressure within an inflatable bladder is
to turn off the pump 21, wait a short period of time, e.g., about
1-5 seconds, to allow the pressure within the inflatable bladder
and the pump manifold 122 to equalize, and then sense the pressure
within the pump manifold 122 with the pressure transducer 128.
Providing a sufficient amount of time to allow the pressures within
the pump manifold 122 and the inflatable bladder to equalize can
result in pressure readings that are accurate approximations of the
actual pressure within the inflatable bladder. In various examples,
the pressure the inflatable bladder being inflated or deflated is
regularly and continuously monitored using one or more pressure
sensors.
[0068] Another method of obtaining a pump manifold pressure reading
that is substantially equivalent to the actual pressure within a
particular inflatable bladder is through the use of a pressure
adjustment algorithm. This method can function by approximating
pressure within the inflatable bladder based upon a mathematical
relationship between the inflatable bladder pressure and the
pressure measured within the pump manifold 122, during both an
inflation cycle and a deflation cycle, thereby eliminating the need
to turn off the pump 21 in order to obtain a substantially accurate
approximation of the pressure within the particular inflatable
bladder. As a result, a desired pressure set point within the
particular inflatable bladder being inflated or deflated can be
achieved without the need for turning the pump 21 off to allow the
pressures to equalize. The method of approximating a pressure
within an inflatable bladder using a mathematical relationships
between the inflatable bladder pressure and the pump manifold
pressure is described in in the co-pending U.S. application Ser.
No. 12/936,084, entitled "SYSTEM AND METHOD FOR IMPROVED PRESSURE
ADJUSTMENT," filed on Oct. 1, 2010, assigned to the assignee of the
present application, the entirety of which is incorporated herein
by reference.
[0069] FIG. 8 illustrates an example system architecture, for
example that can be used for the operation of a sleep system 300.
The sleep system 300 can include a bed 301, e.g., comprising an
inflatable air mattress, that can be used by a user 303. The sleep
system 300 can further include a central controller 302, a firmness
controller 304, an articulation controller 306, a temperature
controller 308, which can be in communication with one or more
temperature sensors 309, an external network device 310, and at
least one user controlling device, such as a remote control 312, or
a voice controller 316, or both.
[0070] As illustrated in FIG. 8, the central controller 302 can
include the firmness controller 304 and a pump 305. The sleep
system 300 can be configured as a star topology with the central
controller 302 and the firmness controller 304 functioning as the
hub and the articulation controller 306, the temperature controller
308, the external network device 310, the remote control 312, and
the voice controller 316 functioning as possible spokes, also
referred to herein as components. Thus, in various examples,
central controller 302 can act as a relay between the various
components.
[0071] The central controller 302 can monitor communications (e.g.,
control signals) between the components even if the communication
is not being relayed through the central controller 302. For
example, in an example, the user 303 can send a command to the
temperature controller 308 using the remote control 312 and the
central controller 302 can monitor for the command and check to
determine if instructions are stored at the central controller 302
to override the command (e.g., it conflicts with a previous
setting). The central controller 302 can also log the command for
future use (e.g., determining a pattern of user preferences for the
components).
[0072] In other examples, different topologies may be used. For
example, the components and the central controller 302 can be
configured as a mesh network in which each component can
communicate with one or all of the other components directly,
bypassing the central controller 302. A combination of topologies
also can be used. For example, the remote control 312 can
communicate directly to the temperature controller 308 but also can
relay the communication to the central controller 302.
[0073] In various examples, the controllers and devices illustrated
in FIG. 8 can each include a processor, a storage device, and a
network interface. The processor can be a general purpose central
processing unit (CPU) or application-specific integrated circuit
(ASIC), etc. The storage device can include volatile or
non-volatile static storage (e.g., Flash memory, RAM, EPROM, etc.).
The storage device can store instructions which, when executed by
the processor, can configure the processor to perform the
functionality described herein. For example, a processor of the
firmness controller 304 can be configured to send a command to a
relief valve to decrease the pressure in a bed.
[0074] In various examples, the network interface of the components
can be configured to transmit and receive communications in a
variety of wired and wireless protocols. For example, the network
interface can be configured to use the 802.11 standards (e.g.,
802.11a/b/c/g/n/ac), PAN network standards such as 802.15.4 or
Bluetooth, infrared, cellular standards (e.g., 3G/4G etc.),
Ethernet, and USB for receiving and transmitting data. The previous
list is not intended to exhaustive and other protocols may be used.
Not all components of FIG. 8 need to be configured to use the same
protocols. For example, the remote control 312 can communicate with
the central controller 302 via Bluetooth while the temperature
controller 308 and the articulation controller 306 can be connected
to the central controller using 802.15.4. Within FIG. 8, the
lightning-shaped connectors represent wireless connections and the
solid lines represent wired connections. However, the connections
between the components is not limited to such connections and each
connection can be wired or wireless. For example, the voice
controller 316 can be connected wirelessly to the central
controller 302.
[0075] Moreover, in various examples, the processor, the storage
device, and the network interface of a component can be located in
different locations than various elements used to affect a command.
For example, the firmness controller 302 can have a pump that is
housed in a separate enclosure than the processor used to control
the pump. Similar separation of elements can be employed for the
other controllers and devices in FIG. 8.
[0076] In various examples, the firmness controller 304 can be
configured to regulate pressure in one or more inflatable bladders.
For example, the firmness controller 304 can include a pump such as
described with reference to FIGS. 1 and 7 (see e.g., pump 21). The
firmness controller 304 can respond to commands to increase or
decrease a pressure in an inflatable bladder of a mattress. The
commands can be received from another component or based on stored
application instructions that are part of the firmness controller
304.
[0077] In the example shown in FIG. 8, the central controller 302
includes the firmness controller 304. In such an example, the
processor of the central controller 302 and the processor for the
firmness controller 304 can be the same processor. Furthermore, the
pump can also be part of the central controller 302. Accordingly,
the central controller 302 can be responsible for pressure
regulation as well as other functionality as described in further
portions of this disclosure.
[0078] The articulation controller 306 can be configured to adjust
a position of the bed 301 by adjusting a foundation 307 that
supports the bed. Separate positions can be set for two different
beds (e.g., two twin beds placed next to each other) or for two
different sleep areas of the same bed. The foundation 307 can
include more than one zone, e.g., a head zone 318, a lumbar zone
319, and a foot zone 320, that can be independently adjusted. Each
zone 318, 319, 320 can include a separate inflatable bladder or set
of inflatable bladders, wherein the pressure within the inflatable
bladder(s) associated with each zone 318, 319, 320 can be
independently adjusted by the firmness controller 304. The
articulation controller 306 can also be configured to provide
different levels of massage to a person on the bed.
[0079] The temperature controller 308 can be configured to
increase, decrease, or maintain the temperature of the user 303.
For example, a pad can be placed on top of or be part of the air
mattress. A cooling or heating fluid, such as cooled or heated air,
can be pushed through the pad and vented to cool or heat the user
303 on the bed 301. Conversely, the pad can include a heating
element that can be used to keep the user 303 warm. In various
examples, the pad can include the temperature sensor 309 and the
temperature controller 308 can receive temperature readings from
the temperature sensor 309. Alternatively, the temperature sensor
309 can be separate from the pad, e.g., part of the air mattress or
foundation. Further details of a system for heating or cooling the
user 303, e.g., that can be controlled by the temperature
controller 308, is described in the co-pending patent application
entitled "DISTRIBUTION PAD FOR A TEMPERATURE CONTROL SYSTEM," U.S.
application Ser. No. 13/728,087, filed on Dec. 27, 2012, assigned
to the assignee of this patent application, which is incorporated
by reference herein in its entirety
[0080] Additional controllers can communicate with the central
controller 302. These controllers can include, but are not limited
to, illumination controllers for turning on and off light elements
placed on and around the bed and outlet controllers for controlling
power to one or more power outlets.
[0081] The external network device 310, the remote control 312 and
the voice controller 316 can be used to input commands (e.g., from
the user 303 or remote system) to control one or more components of
the sleep system 300. The commands can be transmitted from the
remote control 312, the voice controller 316, or an external
network, and received at the central controller 302. The central
controller 302 can process the command to determine the appropriate
component to route the received command. For example, each command
sent via one of the remote control 312, the voice controller 316,
or the network can include a header or other metadata that
indicates which component the command is for. The header metadata
can also indicate from which controller (e.g., which of the one or
more remote controls 312, the voice controller 316, or the network)
the command was initiated. The central controller 302 can then
transmit the command via a network interface of the central
controller 302 to the appropriate component.
[0082] For example, the user 303 can input a desired firmness or
pressure for a particular zone of the bed 301 into the remote
control 312. The desired pressure or firmness can be encapsulated
in a command data structure that includes a signal corresponding to
the desired pressure and that identifies the firmness controller
304 as the desired component to be controlled. The command data
structure can then be transmitted to the central controller 302.
The command data structure can be encrypted before being
transmitted. The central controller 302 can parse the command data
structure and relay the command to the firmness controller 304. The
firmness controller 304 can then configure the pump 305 to increase
or decrease the pressure within one or more inflatable bladders
associated with the particular zone in order to achieve the
pressure selected by the user 303 (or the pressure associated with
the firmness selected by the user 303) that was originally input
into the remote control 312.
[0083] In various examples, data can be transmitted from a
component back to one or more of the remote controls 312. For
example, the current temperature as determined by a sensor element
of temperature controller 308, e.g., temperature sensor 309, the
pressure in an inflatable bladder as measured by a pressure
transducer, the current position of the foundation, or other
information can be transmitted to central controller 302. The
central controller 302 can then transmit the received information
to the remote control 312 where it can be displayed to the user 303
on a display 322.
[0084] Multiple types of devices can be used to input commands to
control the components of the example sleep system 300. For
example, the remote control 312 can be a mobile device such as a
smart phone or tablet computer running an application. Another
example of a remote control 312 can include a dedicated device for
interacting with the components of the sleep system 300. The remote
control 312 can include a display device 322 for displaying an
interface to the user 303. As described in more detail below, the
interface 322 can include a display of a firmness identifier 324
that provides an easy to read, easy to understand value that
quickly indicates to the user 303 a pressure setting for each zone
318, 319, 320 of the bed 301. In the example shown in FIG. 8, the
bed 301 includes three zones--the head zone 318, the lumbar zone
319, and the foot zone 320. Therefore, the example firmness
identifier 324 shown on the display 322 in FIG. 8 includes a
three-digit number, such that each digit of the firmness identifier
324 corresponds to a specific zone 318, 319, 320, and the value of
each digit corresponds to a prearranged pressure or range or
pressures within the particular zone 318, 319, 320 (described in
more detail below). The remote control 312 can also include one or
more input devices that can include, but are not limited to, a
keypad, a touchscreen, a gesture input device, a motion-capture
device, and a voice control (e.g., the voice controller 316).
[0085] The voice controller 316 can be configured to accept voice
commands from the user 303 to control one or more components. More
than one of the remote control 312 and the voice controller 316 can
be used in tandem.
[0086] The remote control 312 can be configured to pair with one or
more central controllers 302. For each central controller 302, data
can be transmitted to the remote control 312 that includes a list
of components linked with the central controller 302. For example,
if the remote control 312 is a mobile phone, it can be loaded with
an application configured to communicate with central controllers
and the application can be authenticated and paired with the
specific central controller 302 of the sleep system 300. The remote
control 312 can transmit a discovery request to the central
controller 302 to inquire about other components and available
services. In response, the central controller 302 can transmit a
list of services that includes available functions for adjusting
the firmness of one or more zones 318, 319, 320 of the bed 301, the
position of one or more zones 318, 319, 320 of the bed 301, and the
temperature of one or more zones 318, 319, 320 of the bed 301. The
application can then display functions for increasing or decreasing
pressure of one or more inflatable bladders associated with one or
more zones 318, 319, 320, adjusting positions of zones 218, 219,
220 of the bed 301, and adjusting temperature of the bed 301. If
components are added or removed to the sleep system 300 under
control of the central controller 302, an updated list can be
transmitted to the remote control 312 and the interface of the
application can be adjusted accordingly.
[0087] The central controller 302 can be configured as a
distributor of software updates to components in the sleep system
300. For example, a firmware update for the firmness controller 304
can become available. The update can be loaded into a storage
device of the central controller 302 (e.g., via a USB interface or
via an external network device 310). The central controller 302 can
transmit the update to the firmness controller 304 with
instructions to update. The firmness controller 304 can attempt to
install the update. A status message can be transmitted from the
firmness controller 304 to the central controller 302 indicating
the success or failure of the update.
[0088] The central controller 302 can be configured to analyze data
collected by a pressure transducer (e.g., the transducer 128 shown
in FIG. 7) to determine various states of the user 303 lying on the
bed. For example, the central controller 302 can determine the
heart rate or respiration rate of the user 303. Additional
processing can be done using the collected data to determine a
possible sleep state of the user 303. For example, the central
controller 302 can determine when the user 303 falls asleep and,
while asleep, the various sleep states of the user 303.
[0089] In various examples, the external network device 310 can
include a network interface to interact with an external computer,
server, or network for processing and storage of data related to
components in the sleep system 300. For example, the determined
sleep data as described above can be transmitted from the central
controller 302 through the external network device 310 to a network
(e.g., the Internet) for storage or other use. In an example, the
pressure transducer data can be transmitted to the external server
for additional analysis. The external network device 310 can also
analyze and filter the data before transmitting it to the external
server.
[0090] Diagnostic data of the components can also be routed to the
external network device 310 for storage and diagnosis on the
external server. For example, if the firmness controller 304
detects an abnormal pressure reading (e.g., a drop in pressure over
a set period of time that exceeds a set threshold, or a measured
pressure that is below a set point minimum), diagnostic data (e.g.,
sensor readings, current settings, etc.) can be transmitted from
the firmness controller 304 to the central controller 302. The
central controller 302 can then transmit this data to the external
network device 310, and the external device 310 can transmit the
information to the external network, for example via wireless
transmission to an WLAN access point where it can be routed to the
external server for analysis.
[0091] The sleep system 300 can include one or more lights
326A-326F (referred to collectively herein as "lights 326") to
illuminate a portion of a room, e.g., when a user 303 gets out of
the bed 301. The lights 326 can be attached around the foundation
307, e.g., affixed to the foundation around its perimeter. In FIG.
8, the lights 326 are depicted as extending around two sides of the
foundation 307. In other configurations, the lights 326 can extend
around more than two sides of the foundation 307, or only a single
side. The lights 326 can be positioned underneath the foundation
307 to project light outwardly from the foundation 307.

[0093] FIGS. 9A, 9B, 10A, and 10B show examples of user controlling
devices, e.g., handheld remote controls, that can be used to
control a sleep system, such as the sleep system 10 shown in FIGS.
1 and 7 or the sleep system 300 shown in FIG. 8. FIGS. 9A and 9B
show a first example remote control 400 that is configured to
control a dual-zone mattress, e.g., a mattress comprising a support
surface assembly made up of two zones of inflatable bladders, such
as the support surface assembly 80 comprising a first inflatable
bladder 82A (a first zone) and a second inflatable bladder 82B (a
second zone) described above with respect to FIG. 5.
[0094] The remote control 400 includes a display 402 and a set of
controls for controlling operation of the sleep system, such as an
up control 404, a down control 406, a left control 408, and a right
control 410. In an example, the remote control 400 can be
configured to allow a user to select between different mattresses
in a two-person bed, such as mattresses 18A and 18B associated with
sleep areas 20 and 22, respectively, as described above regarding
the sleep system 10 of FIG. 1. For example, the left control 408
can be configured to allow for selection of a "left" side of the
sleep system, e.g., the left side as viewed by a user lying on the
bed with his or her head toward the head end of the sleep system.
Similarly, the right control 410 can be configured to allow for
selection of a "right" side of the sleep system, e.g., the right
side as viewed by a user lying on the bed with his or her head
toward the head end of the sleep system. Upon selection of either
side of the sleep system, the user can then use the controls to
control aspects of the selected side, such as articulation (if the
sleep system comprises an adjustable bed), temperature, and
pressure or firmness of the inflatable bladders of the dual-zone
mattress.
[0095] FIGS. 10A and 10B show a second example remote control 500
that is configured to control a three-zone mattress, e.g., a
mattress comprising a support surface assembly made up of three
zones of inflatable bladders, such as the support surface assembly
90 comprising a first inflatable bladder 92A (a first zone), a
second inflatable bladder 92B (a second bladder), and a third
inflatable bladder 92C (a third zone) described above with respect
to FIG. 6.
[0096] The remote control 500 includes a display 502 and a set of
controls for controlling operation of the sleep system, such as an
up control 504, a down control 506, a left control 508, and a right
control 510. As with remote control 400, the remote control 500 can
be configured to allow a user to select between different
mattresses in a two-person bed. Upon selection of either side of
the sleep system, the user can then use the controls to control
aspects of the selected side, such as articulation (if the sleep
system comprises an adjustable bed), temperature, and pressure or
firmness of the inflatable bladders of the dual-zone mattress.
[0097] In an example, the remote control 400, 500 can be configured
to allow a user to quickly and easily monitor and control the
pressure setting in each zone that is configured to be controlled
by the remote control 400, 500. For example, the remote control 400
of FIGS. 9A and 9B can be configured so that a user can quickly,
easily, and conveniently monitor and control the pressure setting
within both zones of a dual-zone mattress, such as inflatable
bladders 82A and 82B of the support surface assembly 80 shown in
FIG. 5. Similarly, the remote control 500 of FIGS. 10A and 10B can
be configured so that a user can quickly, easily, and conveniently
monitor and control the pressure setting within all three zones of
a three-zone mattress, such as inflatable bladders 92A, 92B, and
92C of the support surface assembly 90 shown in FIG. 6.
[0098] In order to provide for quick, easy, and convenient
monitoring and control of the pressure settings, the remote control
400 can be configured to display a firmness identifier 420A, 420B
(collectively referred to herein as "firmness identifier 420" or
"firmness identifiers 420"), as shown in FIGS. 9A and 9B.
Similarly, as shown in FIGS. 10A and 10B, the remote control 500
can be configured to display a firmness identifier 520A, 520B
(collectively referred to herein as "firmness identifier 520" or
"firmness identifiers 520").
[0099] Each firmness identifier 420, 520 can comprise a plurality
of symbols, with the number of symbols corresponding to the number
of zones of a multi-zone mattress being controlled by the remote
control 400, 500. For example, the firmness identifier 420 of the
remote control 400 corresponds to the pressure setting within the
one or more inflatable bladders of each zone of a dual-zone
mattress such that the firmness identifier 420 comprises two
symbols 422A and 422B (collectively referred to herein as "symbol
422" or "symbol 422"). The example firmness identifier 520 of the
remote control 500 is configured to display the pressure settings
within the one or more inflatable bladders of each zone of a
three-zone mattress such that the firmness identifier 520 comprises
three symbols 522A, 522B and 522C (collectively referred to as
"symbol 522" or "symbols 522").
[0100] Each symbol 422, 522 can correspond to a pressure setting
within the inflatable bladders of a particular zone of inflatable
bladders within a multi-zone mattress. For example for the firmness
identifier 420, the first, or left-most symbol 422A displayed on
the remote control 400 can correspond to a first zone of a
dual-zone mattress, such as the zone of the head bladder 82A for
the support surface assembly 80 shown in FIG. 5, and the second, or
right-most symbol 422B can correspond to a zone of the mattress,
such as the zone of the foot bladder 82B. For the firmness
identifier 520, the first, or left-most symbol 522A displayed on
the remote control 500 can correspond to a first zone of a
three-zone mattress, such as the zone of the head bladder 92A for
the support surface assembly 90 shown in FIG. 6, a second, or
middle symbol 522B can correspond to a second zone, such as the
zone of the lumbar bladder 92B, and the third, or right-most symbol
522C can correspond to a third zone, such as the zone of the foot
bladder 92C.
[0101] In a preferred example, each symbol 422, 522 comprises a
single symbol (e.g., only one number or letter) and the plurality
of symbols (e.g., the two symbols 422A, 422B of the firmness
identifier 420 or the three symbols 522A, 522B, 522C of the
firmness identifier 520) are present on the display 402, 502 in
close proximity, e.g., in a side-by-side manner so that, to a user
looking at the remote control 400, 500 the two symbols 422, 522
will appear as a single unit (e.g., a single number in the case of
numerical digits, or a grouping of letters in the case of
alphabetical letters). The close proximity, e.g. side-by-side
arrangement, of the symbols 422, 522 can allow the user to quickly
and easily view the firmness identifier 420, 520 and determine what
the pressure setting is for each zone of the multi-zone mattress.
The close proximity of the symbols 422, 522 can also permit the
user with an easy-to-understand reference when the user is
attempting to set the pressure or firmness in all the zones of a
multi-zone mattress.
[0102] For example, as described in more detail below, the user can
easily associate the two-symbol firmness identifier 420 of the
remote control 400 with the firmness identifier in both zones of a
dual-zone mattress without needing to think much. Similarly, the
user can easily associate the three-symbol firmness identifier 520
of the remote control 500 with the firmness identifier in each zone
of a three-zone mattress without undue mental burden. After
repeated use, a user will be able to readily determine what the
expected firmness will be in each zone of a multi-zone mattress
simply by looking at the closely-spaced firmness reading 420, 520
and rapidly reading each symbol 422, 522.
[0103] The remote control 400, 500 can be configured so that a user
can control the firmness or pressure within each zone of a
multi-zone mattress at the same time or substantially at the same
time, rather than a user having to select and control each zone
individually.
[0104] The value displayed for each symbol 422, 522 can correspond
to a particular pre-established pressure or range of pressures
within the inflatable bladders of particular zone of inflatable
bladders associated with that particular symbol 422, 522. The term
"value," as used herein when referring to the symbols 422, 522 is
not intended to be limited to a numerical value, as may be
suggested by an ordinary reading of the word "value." Rather,
"value," refers to the specific symbol used and what that symbol
represents (e.g., such that the use of "A" for one of the symbols
422, 522 will have a different meaning, e.g., a different value,
than the use of "B"). For example, the remote control 400, 500 can
be configured so that the value for each symbol 422, 522 is an
integer from 0 to 9 (e.g., 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9), such
that the resulting firmness identifier 420, 520 appears to be a
two-digit number from 00 to 99 (for the firmness identifier 420) or
a three-digit number from 000 to 999 (for the firmness identifier
520).
[0105] In another example, the remote control 400, 500 can be
configured so that the value for each symbol 422, 522 is an
alphabetical letter, such as from the standard basic Latin-script
alphabet (e.g., A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q,
R, S, T, U, V, W, X, Y, and Z), such that the resulting firmness
identifier 420, 520 appears to be a two-symbol grouping of letters
(for the firmness identifier 420, e.g., "AB," "XR," etc.) or a
three-symbol grouping of letters (for the firmness identifier 520,
e.g., "ACQ," or "MRM," etc.). The previous two examples can also be
combined, e.g., with each symbol 422, 522 being an integer number
or an alphabetical letter, so that the firmness identifier 420, 520
can be a two or three-digit number, a two or a three-symbol
grouping of letters, a combination of one number and one letter
(for a two-symbol firmness identifier 420), or a combination of two
numbers and one letter or of one number and two letters (for a
three-symbol firmness identifier 520).
[0106] Symbols other than numbers or letters can be used for each
symbol 422, 522. However a universally understood symbol such as
numbers or letters can be more recognizable for a user,
particularly a set of symbols that are universally or nearly
universally understood to indicate differences in magnitude (e.g.,
that a "9" value is greater in magnitude than a "8," which is
greater in magnitude than a "7," and so on).
[0107] Each particular number, letter, or other symbol of the
symbols 422, 522 can correspond to a predetermined pressure setting
within the one or more inflatable bladders of each zone of the
multi-zone mattress being controlled by the remote control 400,
500. Each predetermined pressure setting and the symbol that it is
associated with can be stored in a memory, such as a memory on the
remote control 400, 500 or on a central controller (e.g.,
controller 50 (FIG. 1) or 302 (FIG. 8)). Therefore, when a
particular symbol value is selected for one of the symbols 422, 522
of the firmness identifier 420, 520, the remote control 400, 500 or
the central controller, or both, can access the memory to retrieve
the desired predetermined pressure setting that had been
pre-associated with the selected symbol value. The retrieved
pressure setting can be used to formulate a control signal that can
be used to control a fluid pump in order to inflate or deflate the
one or more inflatable bladders of the selected zone to the
predetermined pressure associated with the selected symbol
value.
[0108] In an example wherein each symbol 422A, 422B, 522A, 522B,
522C comprises a single integer number (e.g., from 0-9), the remote
control 400, 500 and the system that it controls can be
predetermined so that the value of each symbol corresponds to a
particular pressure or range of pressures within the corresponding
inflatable bladder or zone of a plurality of inflatable bladders.
Table 1 provides a non-limiting example listing of pressures
associated with each integer number.
TABLE-US-00001 TABLE 1 Firmness Identifier Approx. Setting Pressure
(PSI) 0 0.045 1 0.105 2 0.165 3 0.225 4 0.285 5 0.345 6 0.405 7
0.465 8 0.525 9 0.585
[0109] The example remote control 400 in FIG. 9A shows the firmness
identifier 420A as "45." In an example, the system that is
controlled by the remote control 400 can include a mattress
comprising the support surface assembly 80 shown in FIG. 5, with
the remote control 400 being configured so that the first symbol
422A corresponds to the pressure setting within the head bladder
82A and the second symbol 422B corresponds to the pressure setting
within the foot bladder 82B. Therefore, using the example
predetermined pressures of Table 1, the first symbol 422A of the
firmness identifier 420A in FIG. 9A of "4" corresponds to the head
bladder 82A having a pressure of about 0.285 pounds per square inch
(psi) (about 1.96 kilopascal (kPa)) and the second symbol 422B of
"5" corresponds to the foot bladder 82B having a pressure of about
0.345 psi (about 2.38 kPa).
[0110] In an example, the user can operate the remote control 400
to change the firmness identifier 420A in FIG. 9A (e.g. "45") to
the firmness identifier 420B in FIG. 9B (e.g., "29"). An
appropriate control signal can be transmitted to a fluid pump,
e.g., via a central controller, that will cause the fluid pump to
adjust the pressure in the inflatable bladders 82A, 82B
accordingly. In the example, the control signal can be configured
to cause the fluid pump to lower the pressure in the head bladder
82A from about 0.285 psi (about 1.96 kPa) to about 0.165 psi (about
1.14 kPa), corresponding to the "2" value selected for the first
symbol 422A. The control signal can also be configured to cause the
fluid pump to raise the pressure in the foot bladder 82B from about
0.345 psi (about 2.38 kPa) to about 0.585 psi (about 4.03 kPa) to
correspond with the "9" value selected for the second symbol
422B.
[0111] Similarly, the example remote control 500 in FIG. 10A shows
the firmness identifier 520A as "783". In an example, the system
that is controlled by the remote control 500 can include a mattress
comprising the support surface assembly 90 shown in FIG. 6, with
the remote control 500 being configured so that the first symbol
522A corresponds to the pressure setting within the head bladder
92A, the second symbol 522B corresponds to the pressure setting
within the lumbar bladder 92B, and the third symbol 522C
corresponds to the pressure setting within the foot bladder 92C.
Therefore, using the example predetermined pressures of Table 1,
the first symbol 522A of the firmness identifier 520A in FIG. 10A
of "7" corresponds to the head bladder 92A having a pressure of
about 0.465 psi (about 3.21 kPa), the second symbol 522B of "8"
corresponds to the lumbar bladder 92B having a pressure of about
0.525 psi (about 3.62 kPa), and the third symbol 522C of "3"
corresponds to the foot bladder 92C having a pressure of about
0.225 psi (about 1.55 kPa).
[0112] In an example, the user can operate the remote control 500
to change the firmness identifier 520A in FIG. 10A (e.g. "783") to
the firmness identifier 520B in FIG. 10B (e.g., "252"). An
appropriate control signal can be transmitted to a fluid pump,
e.g., via a central controller, that will cause the fluid pump to
adjust the pressure in the inflatable bladders 92A, 92B, 92C
accordingly. In the example, the control signal can be configured
to cause the fluid pump to lower the pressure in the head bladder
92A from about 0.465 psi (about 3.21 kPa) to about 0.165 psi (about
1.14 kPa), corresponding to the "2" value selected for the first
symbol 522A. The control signal can also be configured to cause the
fluid pump to lower the pressure in the lumbar bladder 92B from
about 0.525 psi (about 3.62 kPa) to about 0.345 psi (about 2.38
kPa), corresponding to the "5" value selected for the second symbol
522C, and the control signal can be configured to cause the fluid
pump to lower the pressure in the foot bladder 92C from about 0.225
psi (about 1.55 kPa) to about 0.165 psi (about 1.14 kPa) to
correspond with the "2" value selected for the third symbol
522C.
[0113] The values in Table 1 are merely provided as an example for
the purpose of illustrating one example of pre-configured
association between pressure settings and the values of the symbols
422, 522 that can be used. It is to be understood that the present
disclosure is not limited to the predetermined pressures shown in
Table 1.
[0114] The remote control 400, 500 can be configured so that a user
can control the firmness or pressure within each zone of a
multi-zone mattress at the same time or substantially at the same
time, rather than a user having to select and control each zone
individually. For example, the example remote control 400 can be
configured so that a user can modify the firmness identifier 420,
e.g., the user can simultaneously or substantially simultaneously
select a value for each symbol 422A, 422B, and the central
controller can automatically control the pressure in both zones of
the dual-zone mattress. Similarly, the example remote control 500
can be configured so that a user can modify the firmness identifier
520, e.g., the user can simultaneously or substantially
simultaneously select a value for each symbol 522A, 522B, 522C, and
the central controller can automatically control the pressure in
all three zones of the three-zone mattress. In this way, the remote
control 400, 500 and the firmness identifier 420, 520 can provide
what amounts essentially to a sign-step control action or command
to control multiple aspects of the multi-zone mattress, e.g., the
firmness in multiple zones of the multi-zone mattress.
[0115] The remote control 400, 500 can be configured to control the
firmness identifier 420, 520 using any convenient hardware or
method. For example, the remote control 400, 500 can be configured
so that the up control 404, 504 and the down control 406, 506 can
act as a scrolling control for increasing or decreasing the
firmness identifier 420, 520. The remote control 400, 500 can be
configured so that the "scrolling" of the firmness identifier 420,
520 can proceed as if the firmness identifier 420, 520 was a single
number that is being increased, e.g., rather than a set of discrete
symbols 422, 522 each representing a different pressure setting
within a multi-zone mattress. In this way, control of the firmness
identifier 420, 520 can seem, to the user, as a simple operation of
increasing or decreasing a single value, even though the firmness
identifier 420, 520 actually represents multiple pieces of
information.
[0116] In an example, the first remote control 400 can be
configured so that if the up control 404 is pushed a single time,
it causes the firmness identifier 420 to incrementally increase by
one number, e.g., by increasing the second symbol 422B by one if
the second symbol 422B has a value of 0-8 or increasing the first
symbol 422A by one and setting the second symbol 422B to "0" if the
second symbol 422B is "9." Similarly, if the down control 406 is
pushed one time, the remote control 400 can be configured so that
the firmness identifier 420 is incrementally decreased by one
number. The first remote control 400 can also be configured so that
if the up control 404 or the down control 406 is held down, the
firmness identifier 420 will continuously or substantially
continuously increase or decrease, respectively, e.g., as if the
firmness identifier 420 were on a dial that can be scrolling upward
from 00 toward 99 or downward from 99 toward 00, respectively.
[0117] In an example, the second remote control 500 can be
configured so that if the up control 504 is pushed a single time,
it causes the firmness identifier 520 to incrementally increase by
one number, e.g., by increasing the third symbol 522C by one if the
third symbol 522C has a value of 0-8, or increasing the second
symbol 522B by one and setting the third symbol 522C to "0" if the
third symbol 522C is "9," unless the last two symbols 522B and 522C
are "99," in which case the first symbol 522A can be increased by
one and the second and third symbols 522B and 522C can be set as
"00." If the down control 506 is pushed one time, the remote
control 500 can be configured so that the firmness identifier 520
is incrementally decreased by one number. The first remote control
500 can also be configured so that if the up control 504 or the
down control 506 is held down, the firmness identifier 420 will
continuously or substantially continuously increase or decrease,
respectively, e.g., as if the firmness identifier 520 were
scrolling upward from 000 toward 999 or downward from 999 toward
000, respectively.
[0118] In another example, the left control 408, 508 and the right
control 410, 510 of the remote control 400, 500 can be configured
to allow a user to select a specific symbol 422A, 422B or symbol
522A, 522B, or 522C to adjust at a time (rather than adjusting the
entire firmness identifier 420 or 520 as in the previous example).
For example, when using the second remote control 500 with a
three-zone mattress, the left control 508 can be pressed until the
first symbol 522A is selected, and a desired firmness setting for a
head/shoulder zone can be entered. Next, the right control 510 can
be pressed so that the second symbol 522B is selected, and a
desired firmness setting for a lumbar zone can be entered. Finally,
the right control 510 can be pressed so that the third symbol 522C
is selected, and a desired firmness setting for a leg zone can be
entered.
[0119] In another example, the remote control can include a text
input device, such as a keypad or a touchscreen configured for text
input (not shown). A user can use the text input device to directly
input a desired firmness setting. For example, for a dual-zone
mattress, the remote control can be configured so that when a user
types in "37" using the text input device, a firmness setting of
"3" for a first zone, e.g., a head/shoulder zone, can be set to a
pre-set pressure corresponding to the "3" (e.g., about 0.225 psi
using the example pressures in Table 1) and a second zone, e.g., a
lumbar/leg zone, can be set to a pre-set pressure corresponding to
the "7" (e.g., about 0.465 psi using the example pressures in Table
1).
[0120] In an example, the remote control 400, 500 can be configured
with one or more preset firmness identifiers 420, 520 that a user
can scroll through and select. Each preset firmness identifier can
include a predetermined value for each symbol 422, 522 to
correspond to a predetermined effect. In addition, the remote
control 400, 500 can be configured so that a user can modify one or
more of the preset firmness identifiers so that the user can
customize his or her experience. For example, the user can have a
"normal" preset firmness identifier that they use for most sleeps,
and a "soft" preset firmness identifier, perhaps that the user
selects after an injury or a challenging exercise workout to
account for soreness within the user's joints, muscles, or
both.
[0121] The controls of the remote control can also be configured to
select between control parameters other than pressure or firmness
within zones of the bed. For example, the left control 408, 508 and
the right control 410, 510 of the remote control 400, 500 can be
configured to select between firmness control, articulation
control, and temperature control. Moreover, the remote control 400,
500 can be configured with other display identifiers similar to the
firmness identifier 420, 520, e.g., a "temperature identifier" or a
"position identifier," with each symbol of the other display
identifier corresponding to a different predetermined setting for
the particular control aspect (e.g., temperature or articulation
position) within each zone of a multi-zone mattress.
[0122] The present disclosure is not limited to dual-zone or
three-zone mattresses, as described above with respect to FIGS. 5,
6, 9, and 10. Rather, the sleep system and remote control of the
present disclosure can be configured for a multi-zone mattress
having any number zones. The firmness identifier that is displayed
can include the same number of symbols as the number of zones of
inflatable bladders that are to be controlled, e.g., a symbol for
each zone that is being controlled. For example, a four-zone
mattress can be coupled with a remote control configured to display
a four-symbol firmness identifier (e.g., "2539"), a five-zone
mattress can be coupled with a remote control configured to display
a five-symbol firmness identifier (e.g., "83972"), a six-zone
mattress can be coupled with a remote control configured to display
a six-symbol firmness identifier (e.g., "125952"), and so on.
