PRIORITY DATA
[0001] This application claims priority to U.S. Provisional
Application Ser. No. 61/224,970 filed on Jul. 13, 2009, entitled
"APPARATUS, SYSTEM AND METHOD FOR MULTI-FUNCTION INTELLIGENT SPA
CONTROL," the entire disclosure of which is incorporated by
reference."
FIELD OF THE INVENTION
[0002] The invention relates to control of spa systems. More
particularly, the invention relates to multi-function intelligent
control of pedicure spa systems.
BACKGROUND
[0003] Spa systems, in particular, pedicure spa systems are
becoming increasingly advanced with more and more functions being
added thereto. Bacteria and viruses in the tub of pedicure spa
systems is a health concern. Therefore, it is beneficial to have a
sanitization feature that can sanitize the tub of the pedicure spa
system. In addition, a jet pump is often desirable in a pedicure
spa system to disturb the fluid that is in the tub of the pedicure
spa system. In that regard, a control mechanism for the jet pump is
desirable. Moreover, the temperature of the water for pedicure spa
systems is challenging to regulate when performed by an operator.
Therefore, it is beneficial to have a temperature sensing mechanism
that can monitor the temperature of the water and provide feedback
that can then be used to regulate the temperature of water into the
tub. Also, additional lighting for the operator of the pedicure spa
system (or technician providing pedicure services) is desirable.
Moreover, having a water level sensor that can sense the level of
water in the tub is desirable to ensure that the tub has a
predetermined level of water therein. In this regard, the water
level sensor is helpful to make sure the jet pump is not operating
while the water level is below the jet pump. Also, the water level
sensor is helpful to determine when the water level has reached a
particular height with respect to the tub. Moreover, for drainage
of the tub of a pedicure spa system it may be desirable or
necessary to have a drainage pump that can remove the used water.
In that regard, a control mechanism for the drainage pump is
desirable.
[0004] It is desirable for pedicure spa systems to have the
features noted above. An implementation having these features will
entail control mechanisms, sensing, and monitoring requirements.
Accordingly, what is desirable is a pedicure spa system that
implements the features noted above and includes an integrated
controller to control such features. Moreover, also desirable is a
controller that is scalable so that it can be used to control many
of the features noted above, or just a few of the features noted
above. Also desirable is that the controller be partitionable in a
manner so that only one partition is needed for retrofitting
existing pedicure spa systems without requiring another partition
of the controller.

with only one of the casings 184, 185 is able to do so without
having to purchase both casings. The casings 184 and 185 have
securing members 198,190 and 193, 194, respectively, that are used
to fasten and secure the corresponding casing to the bottom of the
pedicure spa systems 20 and 60 respectively shown in FIGS. 1 and
2.
[0033] The casing 184 includes connector valves 200 and 201 that
are coupled between the respective cold and hot water inputs, such
as the ones 109 and 110 described in FIG. 4, and cold and hot water
supplies. Each of the connector valves 200 and 201 respectively
regulates the flow of cold and hot water from the respective cold
and hot water supplies and into the water mixing/sanitizing
chamber. The casing 184 also includes an ionizer sanitizer 205 that
has electrodes 206 and 207 that extend into the water
mixing/sanitizing chamber. Each of the electrodes 206 and 207 also
extend out of the casing 184 and are coupled to outputs of the
electronic/firmware chamber. Accordingly, electrical signals sent
from the electronic/firmware chamber may energize the electrodes
206 and 207. In turn, the ionizer sanitizer 205 injects
sanitization ions into the water disposed within the water
mixing/sanitizing chamber of casing 184. The water is flowed into
the tub and these injected sanitization ions kill the bacteria and
viruses present in the tub.
[0034] The casing 184 further includes a temperature sensor 210
that has thermo-coupling probes 211 and 212 that extend into the
water mixing/sanitizing chamber of casing 184 and contact the water
disposed therein. The thermo-coupling probes 211 and 212 also
extend out of the casing 184 and are coupled to an electrical
contact of the casing 185 for transmitting temperature sensor data
to the electronic/firmware chamber.
[0035] The casing 184 also includes output water connectors 215 and
216 that respectively function as mixed water output ports such as
the ones 118 and 119 described in FIG. 4. The output connectors 215
and 216 are coupled to or are integral with tubing (not shown) for
supplying the mixed water to various component of the spa system.
For example, the output water connector 215 supplies mixed water to
the shower wand 65 of pedicure spa system 60 of FIG. 2A. The output
water connector 216 supplies mixed water into the basin 24 via the
waterfall feature 34 of the pedicure spa systems 20 and 60 of FIGS.
1 and 2, respectively.
[0036] The casing 185 includes a power cord 224 that has a
three-pronged male connector for connecting to a 120V AC wall
outlet. In alternative embodiments, the power cord 224 can have a
male connector for connecting to a 220V AC wall outlet. The power
cord 224 provides power to a power supply input such as the one 134
described in FIG. 4. The casing 185 further includes an LED 225
that functions as a power indicator such as the one 135 described
in FIG. 4. The LED 225 lights up when power is supplied to the
electronic/firmware chamber of casing 185. In addition, the casing
185 includes a continuous power outlet 226 that functions as a
continuous power output port such as the one 136 described in FIG.
4 to supply continuous AC power that may be needed by other
components in the pedicure spa systems 20 and 60 of FIGS. 1 and 2,
respectively.
[0037] Moreover, the casing 185 includes electrical connectors 230
and 231 that function to respectively provide signals that regulate
the flow of cold and hot water into the water mixing/sanitizing
chamber via the cold and hot water valve connectors 200 and 201.
Furthermore, the casing 185 includes jet pump AC power outlets 235
and 236 that respectively function as jet pump power supply output
ports such as the ones 144 and 145 described in FIG. 4. The casing
185 further includes a discharge pump AC power outlet 237 that
functions as a discharge pump power supply output port such as the
one 146 described in FIG. 4. In alternative embodiments a
technician light that is powered off of AC power can be coupled to
one of the AC power outlets 235-237. Also, in other embodiments the
AC power outlets 235-237 can be connected to other devices that run
off of AC power. Moreover, the casing 185 includes a discharge pump
air switch 240 that functions as a discharge pump switch such as
the one 151 described in FIG. 4. The discharge pump air switch 240
turns on and off the discharge pump feature of the pedicure spa
systems 20 and 60 of FIGS. 1 and 2, respectively. Further, the
casing 185 includes a jet and light air switch 241 that functions
as a jet pump switch such as the one 150 described in FIG. 4. The
jet and light air switch 241 turns on and off the jet pump feature
of the pedicure spa systems 20 and 60 of FIGS. 1 and 2,
respectively.
[0038] The casing 185 includes a temperature sensor electronic
connector 245 that functions as a temperature sensor input such as
the one 155 described in FIG. 4 and receives signals from the
temperature sensor 210. The temperature sensor electronic connector
245 provides connection to wires that are coupled to the
temperature sensor probes 211 and 212 for receiving the temperature
sensing signals from the temperature sensor 210. In addition, the
casing 185 includes a display and control electrical connector 246
that functions as a display and control feature such as the one 156
described in FIG. 4. The display and control electrical connector
246 couples to a display and control interface 247 that functions
as a display and control interface such as the one 68 described in
FIG. 2A. The casing 185 further includes a temperature setting
switch connector 251 that mates a temperature setting switch, such
as the one 157 described in FIG. 4, to the display and control
interface 247. When coupled to the display and control interface
247, the temperature setting switch connector 251 receives
temperature setting inputs from the operator via the display and
control interface 247. In turn, the electronics/firmware chamber
processes the temperature setting input and generates control
signals to change the amount of cold and hot water that is supplied
into the water mixing/sanitizing chamber of casing 184. In this
manner, the operator can accurately change the temperature of the
water that is supplied into the basin 24 of the pedicure spa system
60 shown in FIG. 2A. It should be noted that the pedicure spa
system 20 shown in FIG. 1 can be retrofitted with this feature in
place of the manually operated faucet 35 for better control of the
water temperature in the basin.
[0039] Similarly, the casing 185 includes a water level sensor
electrical connector 252 that functions as a water level sensor
input, such as the one 160 described in FIG. 4, for receiving a
signal from a water level sensor (not shown) that is installed on
the outer surface of the basin 24 of the pedicure spa system 60 of
FIG. 2A. The water level sensor electrical connector 252 is coupled
to a pair of wires that connect to the water level sensor disposed
in the basin 24. The water level sensor electrical connector 252
receives signals that indicate the level of the water in the basin
24. In particular, the signals indicate whether the water has
filled up to a predetermined height along the basin 24. In this
regard, the electronic and firmware chamber receives these signals
from the water level sensor electrical connector 252 and processes
them to determine whether more or less water is needed in the basin
24. If more water is needed, the electronics/firmware chamber may
generate controls signals to flow more water into the water
mixing/sanitizing chamber and supplied into the basin 24 until the
proper water level is achieved in the basin.
[0040] The casing 185 further includes light power outlets 256 and
257 that function as light power supply outputs such as the ones
164 and 165 described in FIG. 4. The power supply outlets 256, 257
are DC power supply outlets. Referring back FIG. 2A, one of the DC
power supply outlets 256, 257 is coupled to the technician light 67
of the spa system 60. In alternative embodiments, the DC power
supply outlets 256, 257 may be coupled to other devices that run
off of DC power. In addition, the casing 185 includes a sanitizer
electrical connector 258 that functions to couple a water sanitizer
controller to a sanitizer mechanism such as the ones 166 and 113
described in FIG. 4, respectively. The sanitizer electrical
connector 258 couples wires between the water sanitizer controller
and the sanitizer mechanism. The wires supply signals from the
sanitizer controller to the sanitizer electrodes 206, 207. These
signals control the electrodes 206, 207 for altering the amount of
ionization of the water in the water mixing/sanitizing chamber, and
therefore changing sanitization levels of the water being mixed
therein.
[0041] As best seen in FIG. 8, the casing 184 has securing members
270 and 271. Moreover, the casing 185 has securing members 272 and
273. By fastening the securing members 270-273 to the coupling
member 186, each of the casings 184, 185 are coupled together via
the coupling member 186. In this manner, the casings 184 and 184
are coupled to provide a unit that can be attached to the underside
of the pedicure spa system 60 of FIG. 2A. Also, the casing 185 can
be independently coupled to the underneath of the pedicure spa
system of FIGS. 1 and 2, separate from the casing 184. This is
particularly advantageous when the functionality of the water
mixing/sanitizing chamber is unnecessary or undesirable, but the
features of the electronic/firmware chamber are desirable.
[0042] Referring to FIGS. 2, 3 and 5, an explanation is now
provided of the spa control system 180 (FIG. 5) being configured
for the pedicure spa system 60 (FIG. 2A). The spa control system
180 is mounted to the underside of the pedicure spa system 60.
Screws that extend through securing members 189, 190, 193, and 194
are screwed into the underside of the pedicure spa system 60 to
securely fasten the spa control system 180. The cold and hot water
valve connectors 200, 201 are coupled by hoses or other suitable
tubing to respective cold and hot water sources of an external
water supply system (not shown). Moreover, the mixed water
connector 215 is coupled by a hose or other suitable tubing to the
shower wand 65 and the mixed water connector 216 is coupled by a
hose to the waterfall feature 34. Also, the discharge pump switch
240 is coupled to the discharge pump air switch 38 and the jet and
light air switch 241 is coupled to the jet pump air switch 39.
Moreover, the discharge pump (not shown) that is disposed
underneath the tub 23 includes a power cord that is coupled to the
discharge pump AC power outlet 237. In addition, the jet pump 66
includes a power cord that is coupled to one of the jet pump AC
power outlets 235, 236.
[0043] The temperature sensor 210 is coupled to the temperature
sensor electrical connector 245 with electrical wires. The
electrical wires receive signals from the temperature sensor 210
for processing by the electronic/firmware chamber. In addition, the
ionizer sanitizer 205 is coupled to the sanitizer electrical
connector 258 with electrical wires. In particular, each electrical
wire is coupled to one of the electrodes 206, 207 for receiving
signals from the sanitizer electrical connector 258 that cause the
ionizer sanitizer 205 to inject sanitization ions into the water in
the water mixing/sanitizing chamber. The display and controller
connector 246 and the temperature setting switch connector 251 are
respectively coupled to the display and control interface and the
temperature control with electrical wires. Furthermore, the water
level sensor connector 252 is coupled by electrical wires to the
water level sensor (not shown) that is installed on the outer
surface of the basin 24. Also, the light power outlets 256 and 257
are coupled to lights, for example, the light 30 that provides
under water lighting. Also, the continuous power AC outlet 226 can
be used to plug in another device that needs continuous AC power.
In addition, the power cord 224 is coupled to an AC wall outlet
(not shown) to provide power to the electronic/firmware
chamber.
[0044] Referring to FIGS. 2-8, an explanation is now provided of
the operation of the spa control system 180 (FIG. 5) of the
pedicure spa system 60. In operation, the power LED indicator 225
lights up when the spa control system 180 receives power from the
wall outlet. An operator of the pedicure spa system 60 uses the
display and control interface 68 to control the pedicure spa system
60. For example, the operator fills the basin 24 of the tub 61 by
using the display and control interface 68 to turn on the water.
The operator further sets the desired temperature of the water
using the display and control interface 68. In turn, the
electronics/firmware chamber processes the operator's input from
the display and control interface 68. For example, the
electronics/firmware chamber supplies signals at the electrical
connectors 230, 231 that respectively control the cold and hot
connector valves 200, 201. In this manner, the spa control system
180 regulates the mixture of cold and hot water that enters the
water mixing/sanitizing chamber via the cold and hot water input
ports. As the water passes by the temperature sensor probes 211,
212, these probes generate signals that are supplied back to the
electronics/firmware chamber via wires that are coupled to the
temperature sensor electronic connector 245. The
electronics/firmware chamber processes these temperature sensor
signals and generates signals that are supplied to the display and
control interface 68 for displaying the temperature of the water in
the water mixing/sanitizing chamber.
[0045] When the water is in the water mixing/sanitizing chamber,
the water is sanitized by the ionizer sanitizer 205. The electrodes
206, 207 of the ionizer sanitizer 205 receive signals from the
sanitizer electrical connector 258 for regulating the ionization
levels. For example, when the electrodes 206, 207 receive signals
from the sanitizer electrical connector 258, the ionizer sanitizer
205 injects sanitization ions into the water in the water
mixing/sanitizing chamber of casing 184. These injected
sanitization ions kill the bacteria and viruses in the basin 24 of
the tub 61. In due course, the water in the water mixing/sanitizing
chamber is supplied to the basin 24. In particular, the water is
forced out of the output water connector 216 through a tube and out
of the waterfall 34. If the operator engages the shower wand 65,
the water in the water mixing/sanitizing chamber is supplied to the
shower wand 65. In particular, the water is forced out of the
output water connector 215 through a tube and out of the shower
wand 65.
[0046] The operator of the pedicure spa system 60 can engage the
jet pump 66 (FIG. 3) by pressing the jet switch 39 that toggles on
and off the jet pump 66. In addition, the operator of the pedicure
spa system 60 can engage the discharge pump (not shown) by pressing
the discharge switch 40 that toggles on and off the discharge pump.
While providing services to a user, the operator can use the
technician light 67. The operator engages the technician light 67
from the display and control interface 68. In particular, the
operator presses a button on the display and control interface 68
to toggle on and off the technician light 67.
[0047] When the operator is filling the basin 24 with water from
the water mixing/sanitizing chamber, a water level sensor (not
shown) that is installed on the outer surface of the basin 24
senses whether the water is at or below a predetermined level. The
output of this water level sensor is coupled to the water level
sensor connector 252 on the casing 185. In turn, these signals are
processed by the electronics/firmware chamber to determine the
proper course of action. For example, if the water level in the
basin 24 is below a predetermined level the electronics/firmware
chamber will continue to fill the basin 24 with water. Otherwise
the electronics/firmware chamber will refrain from filling up the
basin 24 by shutting off the valve that regulates the flow of water
into the mixing/sanitizing chamber. In addition, if the water
reaches another predetermined level that is undesirable the
overflow 29 will allow the unwanted level of water to be drained
from the tub 61.
[0048] The operator of the pedicure spa system 60 can drain the
basin 24 by opening the drain stopper 28. The operator opens the
drain stopper 28 by turning the overflow and drain opener 29. Then,
the operator presses the discharge switch 38 to activate the
discharge pump (not shown) that is located underneath the tub 23.
The discharge pump sucks the water from the basin 24. In this
regard, the basin 24 is drained and can be re-filled again for
another user in the manner described above.
[0049] FIG. 9A illustrates a portion 300 of a pedicure spa system
that is an alternative to the pedicure spa systems 20 and 60 of
FIGS. 1 and 2. The portion 300 of the pedicure spa system shown in
FIG. 9A includes a tub 304 and a basin 308. The basin 308 has an
inner surface 30 and an outer surface 310. The outer surface has
coupled thereto a remote water level sensor 314. The remote water
level sensor 314 is a capacitive sensor that is developed by LURACO
Technologies, Inc. The remote water level sensor 314 detects the
level of the water in the basin 308. Alternatively, the water level
sensor 314 is another type of remote sensor like an optical sensor.
In yet another embodiment, the sensor 314 is coupled to the inner
surface 309 of the basin 308. In that regard, in some embodiments,
the inner surface 309 has disposed therein a water level sensor
that detects the level of the water in the basin 308. In general, a
variety of different types of sensors can be implemented to detect
the level of water in the basin 308. In addition, the water level
sensor may positioned in various locations. For example, the water
level sensor may be coupled to the inner surface 309 of the basin
308, disposed therein, disposed in the basin 308, or disposed in
the outer surface 310 of the basin 308.
[0050] FIG. 9B is a more detailed view of the remote water level
sensor that is shown in the portion 300 of the pedicure spa system
of FIG. 9A. As shown in FIG. 9B, the remote water level sensor 314
has a connector 320 that supplies a signal and connects to a water
level sensor input of a controller. For example, in an embodiment,
the connector 320 of the remote water level sensor 314 is coupled
to the water level sensor input 160 of the electronics and firmware
chamber 105. In that regard, the connector 320 supplies a signal
from the remote water level sensor 314 to the electronics and
firmware chamber 105. In turn, the chamber 105 processes that
signal to determine the level of the water in the basin 308 and
control the pedicure spa system in response to that signal.
[0051] The embodiments discussed above with respect to the spa
control system 180 of FIGS. 5-8 and the pedicure spa system 60 of
FIG. 2A show the spa control system 180 having the
electronics/firmware chamber and the water mixing/sanitizing
chamber coupled together. However, alternative embodiments of the
pedicure spa system may use the electronics/firmware chamber
independent of the water mixing/sanitizing chamber. For example,
this is particularly desirable in pedicure spa system embodiments
that have a manually operated faucet similar to the one shown in
the pedicure spa system 20 of FIG. 1. In this regard, the
electronics/firmware chamber of casing 185 is used to provide power
supply and operating features to that pedicure spa system while
using the hand operated faucet.
[0052] FIG. 10 illustrates a pedicure spa system 400 that is an
alternative configuration of the pedicure spa system 20 shown in
FIG. 1, and also in which various embodiments disclosed herein may
be implemented. FIG. 10 does not show all aspects of the pedicure
spa system 400. FIG. 10 shows only portions of the pedicure spa
system 400 that are relevant to an understanding of the embodiment
presently under discussion. Similar features of the pedicure spa
systems 20 and 400 respectively shown in FIGS. 1 and 10 are
numbered the same for the sake of clarity and simplicity. Moreover,
the following discussion focuses primarily on the differences.
[0053] The pedicure spa system 400 includes a fluid chamber 405
that is coupled between the manually operated faucet 35 and the
basin 24. The fluid chamber 405 includes the sanitizer 113 that
sanitizes fluid in the fluid chamber 405. In addition, the fluid
chamber 405 includes a fluid valve 410 that regulates the flow of
fluid from the fluid chamber 405 to the basin 24. The pedicure spa
system 400 also includes the fluid level sensor 314 that is coupled
to the outer surface of the basin 24 in a manner that is similar to
the manner shown in FIGS. 9A and 9B.
[0054] The pedicure spa system 400 further includes the intelligent
electronics and firmware chamber 105. The electronics and firmware
chamber 105 can be attached to the underside of the pedicure spa
system 400 as discussed above with regard to the pedicure spa
system 60 of FIG. 2A. The jet output 144 of the electronics and
firmware chamber 105 is coupled to the fluid valve 410 for
controlling the flow of fluid from the fluid chamber 405 to the
basin 24. Moreover, in the pedicure spa system 400 the jet pump
switch 150 of the electronics and firmware chamber 105 allows the
operator to turn on or off the delivery of fluid from the fluid
chamber 405 to the basin 24. In addition, the water level sensor
input 160 of the electronics and firmware chamber 105 is coupled to
the fluid level sensor 314. As previously explained, the water
level sensor input 314 receives a signal from the water level
sensor 314. In response to the signal received by the water level
sensor input 160 from the water level sensor 314, the electronics
and firmware chamber 105 can turn on or off a jet pump (not shown)
of the pedicure spa system 400. The jet pump of the pedicure spa
system 400 is similar to the jet pump 66 shown in FIG. 3.
[0055] Now provided is an explanation of the operation of the
pedicure spa system 400 shown in FIG. 10. In operation, the
operator of the pedicure spa system 400 fills the fluid chamber 405
by manually turning the faucet 35. The operator can adjust the
faucet 35 to allow a mixture of hot and cold water into the fluid
chamber 405. The water in the fluid chamber 405 is then sanitized
by the sanitizer 113. The sanitizer 113 is controlled by the
electronics and firmware chamber 105 and sanitizes the water in the
fluid chamber 405 as previously explained. The fluid valve 410 is
controlled by the electronics and firmware chamber. In particular,
the operator uses the switch 150 of the electronics and firmware
chamber 105 to turn on or off the delivery of fluid from the fluid
chamber 405 to the basin 24. The electronics and firmware chamber
105 controls the fluid valve 410 in response to the switch 150
being in either the on or off position. In particular, the jet
output 144 of the electronics and firmware chamber 105 controls the
fluid valve 410 in response to the switch 150 being turned on or
off. When the switch is turned off the jet output 144 closes the
fluid valve 410 so that water from the fluid chamber 104 is
prevented from flowing into the basin 24. When the switch is turned
on the jet output 144 opens the fluid valve 410 so that ware in the
fluid chamber 405 is allowed to flow into the basin 24.
[0056] In further detail, the electronics and firmware chamber 105
includes firmware that allows a jet pump (not shown) in the
pedicure spa system 400 to be turned on when the water level in the
basin 24 has reached a predefined level. In particular, the water
level sensor 314 monitors when the water in the basin 24 reaches a
predetermined level. When the water in the basin 24 reaches the
predetermined level the fluid level sensor 314 sends a signal to
the water level sensor input 160 to indicate that the predetermined
water level has been reached. In response to the indication that
the water in the basin 24 has reached a predetermined level, the
electronics and firmware chamber 105 turns on the jet pump of the
spa system 400.
[0057] In an alternative embodiment, the electronics and firmware
chamber 105 provides automatic shut-off of the flow of water from
the fluid chamber 405 into the basin 24. For example, when the
water in the basin 24 reaches a predetermined level the fluid level
sensor 314 sends a signal to the water level sensor input 160 of
the electronics and firmware chamber. In response to the indication
that the water in the basin 24 has reached a predetermined level,
the electronics and firmware chamber 105 controls the fluid valve
410 so that further water is prevented from flowing from the fluid
chamber 405 into the basin 24.
[0058] In alternative embodiments, the faucet may also be replaced
and retrofitted with the mixing/sanitizing chamber of casing 184.
In some instances, an existing pedicure spa system may be
retrofitted with additional features that require control and power
supplies. In that regard, these embodiments benefit from using the
electronics/firmware chamber of casing 185 to provide the
additional control electronics and power supply features that are
necessary to support the retrofitted pedicure spa system.
[0059] Moreover, the embodiments discussed above have a water level
sensor (not shown) that is a remote sensor that is typically
installed on the outer surface of the basin 24 of the pedicure spa
systems 20 (FIG. 1) and 60 (FIG. 2A), and detects the water level
through wall of the basin 24. In an alternative embodiment, the
water level sensor is disposed in a portion of the inner surface of
the basin 24 and detects water therein.
[0060] While the preceding description shows and describes one or
more embodiments, it will be understood by those skilled in the art
that various changes in form and detail may be made therein without
departing from the spirit and scope of the present disclosure. For
example, the various steps of the described methods may be executed
in a different order or executed sequentially, combined, further
divided, replaced with alternate steps, or removed entirely. In
addition, various functions illustrated in the methods or described
elsewhere in the disclosure may be combined to provide additional
and/or alternate functions. Moreover, the methods and apparatuses
disclosed herein are applicable in a jacuzzi system, a whirlpool
system, a bathtub system, and other suitable spa systems.
Therefore, the claims should be interpreted in a broad manner,
consistent with the present disclosure.
