FIELD OF THE INVENTION
[0002] The present invention relates to a system for monitoring
health, wellness and fitness, and in particular, to a system for
collecting, using a sensor device, and storing at a remote site
data relating to an individual's physiological state, lifestyle,
and various contextual parameters, and making such data and
analytical information based on such data available to the
individual, preferably over an electronic network.
BACKGROUND OF THE INVENTION
[0003] Research has shown that a large number of the top health
problems in society are either caused in whole or in part by an
unhealthy lifestyle. More and more, our society requires people to
lead fast-paced, achievement-oriented lifestyles that often result
in poor eating habits, high stress levels, lack of exercise, poor
sleep habits and the inability to find the time to center the mind
and relax. Recognizing this fact, people are becoming increasingly
interested in establishing a healthier lifestyle.
[0004] Traditional medicine, embodied in the form of an HMO or
similar organizations, does not have the time, the training, or the
reimbursement mechanism to address the needs of those individuals
interested in a healthier lifestyle. There have been several
attempts to meet the needs of these individuals, including a
perfusion of fitness programs and exercise equipment, dietary
plans, self-help books, alternative therapies, and most recently, a
plethora of health information web sites on the Internet. Each of
these attempts are targeted to empower the individual to take
charge and get healthy. Each of these attempts, however, addresses
only part of the needs of individuals seeking a healthier lifestyle
and ignores many of the real barriers that most individuals face
when trying to adopt a healthier lifestyle. These barriers include
the fact that the individual is often left to himself or herself to
find motivation, to implement a plan for achieving a healthier
lifestyle, to monitor progress, and to brainstorm solutions when
problems arise; the fact that existing programs are directed to
only certain aspects of a healthier lifestyle, and rarely come as a
complete package; and the fact that recommendations are often not
targeted to the unique characteristics of the individual or his
life circumstances.
SUMMARY OF THE INVENTION
[0005] An apparatus for monitoring human status parameters is
disclosed which includes at least two sensors adapted to be worn on
an individual's body. At least one of the sensors is a
physiological sensor selected from the group consisting of
respiration sensors, temperature sensors, heat flux sensors, body
conductance sensors, body resistance sensors, body potential
sensors, brain activity sensors, blood pressure sensors, body
impedance sensors, body motion sensors, oxygen consumption sensors,
body chemistry sensors, body position sensors, body pressure
sensors, light absorption sensors, body sound sensors,
piezoelectric sensors, electrochemical sensors, strain gauges, and
optical sensors. The sensors are adapted to generate data
indicative of at least a first parameter of the individual and a
second parameter of the individual, wherein the first parameter is
a physiological parameter. The apparatus also includes a processor
that receives at least a portion of the data indicative of the
first parameter and the second parameter. The processor is adapted
to generate derived data from at least a portion of the data
indicative of a first parameter and a second parameter, wherein the
derived data comprises a third parameter of the individual. The
third parameter is an individual status parameter that cannot be
directly detected by either of the at least two sensors.
[0006] In an alternate embodiment, an apparatus for monitoring
human status parameters is disclosed that includes at least two
sensors adapted to be worn on an individual's body selected from
the group consisting of physiological sensors and contextual
sensors, wherein at least one of the sensors is a physiological
sensor. The sensors are adapted to generate data indicative of at
least a first parameter of the individual and a second parameter of
the individual, wherein the first parameter is physiological. The
apparatus also includes a processor for receiving at least a
portion of the data indicative of at least a first parameter and a
second parameter, the processor being adapted to generate derived
data from the data indicative of at least a first parameter and a
second parameter. The derived data comprises a third parameter of
the individual selected from the group consisting of ovulation
state, sleep state, calories burned, basal metabolic rate, basal
temperature, physical activity level, stress level, relaxation
level, oxygen consumption rate, rise time, time in zone, recovery
time, and nutrition activity. The third parameter is an individual
status parameter that cannot be directly detected by any of the at
least two sensors.
[0007] In either embodiment of the apparatus, the at least two
sensors may be both physiological sensors, or may be one
physiological sensor and one contextual sensor. The apparatus may
further include a housing adapted to be worn on the individual's
body, wherein the housing supports the sensors or wherein at least
one of the sensors is separately located from the housing. The
apparatus may further include a flexible body supporting the
housing having first and second members that are adapted to wrap
around a portion of the individual's body. The flexible body may
support one or more of the sensors. The apparatus may further
include wrapping means coupled to the housing for maintaining
contact between the housing and the individual's body, and the
wrapping means may support one or more of the sensors.
[0008] Either embodiment of the apparatus may further include a
central monitoring unit remote from the at least two sensors that
includes a data storage device. The data storage device receives
the derived data from the processor and retrievably stores the
derived data therein. The apparatus also includes means for
transmitting information based on the derived data from the central
monitoring unit to a recipient, which recipient may include the
individual or a third party authorized by the individual. The
processor may be supported by a housing adapted to be worn on the
individual's body, or alternatively may be part of the central
monitoring unit.
[0009] The apparatus may be further adapted to obtain life
activities data of the individual, wherein the information
transmitted from the central monitoring unit is also based on the
life activities data. The central monitoring unit may also be
adapted to generate and provide feedback relating to the degree to
which the individual has followed a suggested routine. The feedback
may be generated from at least a portion of at least one of the
data indicative of at least a first parameter and a second
parameter, the derived data and the life activities data. The
central monitoring unit may also be adapted to generate and provide
feedback to a recipient relating to management of an aspect of at
least one of the individual's health and lifestyle. This feedback
may be generated from at least one of the data indicative of a
first parameter, the data indicative of a second parameter and the
derived data. The feedback may include suggestions for modifying
the individual's behavior.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0030] In general, according to the present invention, data
relating to the physiological state, the lifestyle and certain
contextual parameters of an individual is collected and
transmitted, either subsequently or in real-time, to a site,
preferably remote from the individual, where it is stored for later
manipulation and presentation to a recipient, preferably over an
electronic network such as the Internet. Contextual parameters as
used herein means parameters relating to the environment,
surroundings and location of the individual, including, but not
limited to, air quality, sound quality, ambient temperature, global
positioning and the like. Referring to FIG. 1, located at user
location 5 is sensor device 10 adapted to be placed in proximity
with at least a portion of the human body. Sensor device 10 is
preferably worn by an individual user on his or her body, for
example as part of a garment such as a form fitting shirt, or as
part of an arm band or the like. Sensor device 10, includes one or
more sensors, which are adapted to generate signals in response to
physiological characteristics of an individual, and a
microprocessor. Proximity as used herein means that the sensors of
sensor device 10 are separated from the individual's body by a
material or the like, or a distance such that the capabilities of
the sensors are not impeded.
[0031] Sensor device 10 generates data indicative of various
physiological parameters of an individual, such as the individual's
heart rate, pulse rate, beat-to-beat heart variability, EKG or ECG,
respiration rate, skin temperature, core body temperature, heat
flow off the body, galvanic skin response or GSR, EMG, EEG, EOG,
blood pressure, body fat, hydration level, activity level, oxygen
consumption, glucose or blood sugar level, body position, pressure
on muscles or bones, and UV radiation exposure and absorption. In
certain cases, the data indicative of the various physiological
parameters is the signal or signals themselves generated by the one
or more sensors and in certain other cases the data is calculated
by the microprocessor based on the signal or signals generated by
the one or more sensors. Methods for generating data indicative of
various physiological parameters and sensors to be used therefor
are well known. Table 1 provides several examples of such well
known methods and shows the parameter in question, the method used,
the sensor device used, and the signal that is generated. Table 1
also provides an indication as to whether further processing based
on the generated signal is required to generate the data.

[0032] The types of data listed in Table 1 are intended to be
examples of the types of data that can be generated by sensor
device 10. It is to be understood that other types of data relating
to other parameters can be generated by sensor device 10 without
departing from the scope of the present invention.
[0033] The microprocessor of sensor device 10 may be programmed to
summarize and analyze the data. For example, the microprocessor can
be programmed to calculate an average, minimum or maximum heart
rate or respiration rate over a defined period of time, such as ten
minutes. Sensor device 10 may be able to derive information
relating to an individual's physiological state based on the data
indicative of one or more physiological parameters. The
microprocessor of sensor device 10 is programmed to derive such
information using known methods based on the data indicative of one
or more physiological parameters. Table 2 provides examples of the
type of information that can be derived, and indicates some of the
types of data that can be used therefor.

[0034] Additionally, sensor device 10 may also generate data
indicative of various contextual parameters relating to the
environment surrounding the individual. For example, sensor device
10 can generate data indicative of the air quality, sound
level/quality, light quality or ambient temperature near the
individual, or even the global positioning of the individual.
Sensor device 10 may include one or more sensors for generating
signals in response to contextual characteristics relating to the
environment surrounding the individual, the signals ultimately
being used to generate the type of data described above. Such
sensors are well known, as are methods for generating contextual
parametric data such as air quality, sound level/quality, ambient
temperature and global positioning.
[0035] FIG. 2 is a block diagram of an embodiment of sensor device
10. Sensor device 10 includes at least one sensor 12 and
microprocessor 20. Depending upon the nature of the signal
generated by sensor 12, the signal can be sent through one or more
of amplifier 14, conditioning circuit 16, and analog-to-digital
converter 18, before being sent to microprocessor 20. For example,
where sensor 12 generates an analog signal in need of amplification
and filtering, that signal can be sent to amplifier 14, and then on
to conditioning circuit 16, which may, for example, be a band pass
filter. The amplified and conditioned analog signal can then be
transferred to analog-to-digital converter 18, where it is
converted to a digital signal. The digital signal is then sent to
microprocessor 20. Alternatively, if sensor 12 generates a digital
signal, that signal can be sent directly to microprocessor 20.
[0036] A digital signal or signals representing certain
physiological and/or contextual characteristics of the individual
user may be used by microprocessor 20 to calculate or generate data
indicative of physiological and/or contextual parameters of the
individual user. Microprocessor 20 is programmed to derive
information relating to at lease one aspect of the individual's
physiological state. It should be understood that microprocessor 20
may also comprise other forms of processors or processing devices,
such as a microcontroller, or any other device that can be
programmed to perform the functionality described herein.
[0037] The data indicative of physiological and/or contextual
parameters can, according to one embodiment of the present
invention, be sent to memory 22, such as flash memory, where it is
stored until uploaded in the manner to be described below. Although
memory 22 is shown in FIG. 2 as a discrete element, it will be
appreciated that it may also be part of microprocessor 20. Sensor
device 10 also includes input/output circuitry 24, which is adapted
to output and receive as input certain data signals in the manners
to be described herein. Thus, memory 22 of the sensor device 10
will build up, over time, a store of data relating to the
individual user's body and/or environment. That data is
periodically uploaded from sensor device 10 and sent to remote
central monitoring unit 30, as shown in FIG. 1, where it is stored
in a database for subsequent processing and presentation to the
user, preferably through a local or global electronic network such
as the Internet. This uploading of data can be an automatic process
that is initiated by sensor device 10 periodically or upon the
happening of an event such as the detection by sensor device 10 of
a heart rate below a certain level, or can be initiated by the
individual user or some third party authorized by the user,
preferably according to some periodic schedule, such as every day
at 10:00 p.m. Alternatively, rather than storing data in memory 22,
sensor device 10 may continuously upload data in real time.
[0038] The uploading of data from sensor device 10 to central
monitoring unit 30 for storage can be accomplished in various ways.
In one embodiment, the data collected by sensor device 10 is
uploaded by first transferring the data to personal computer 35
shown in FIG. 1 by means of physical connection 40, which, for
example, may be a serial connection such as an RS232 or USB port.
This physical connection may also be accomplished by using a
cradle, not shown, that is electronically coupled to personal
computer 35 into which sensor device 10 can be inserted, as is
common with many commercially available personal digital
assistants. The uploading of data could be initiated by then
pressing a button on the cradle or could be initiated automatically
upon insertion of sensor device 10. The data collected by sensor
device 10 may be uploaded by first transferring the data to
personal computer 35 by means of short-range wireless transmission,
such as infrared or RF transmission, as indicated at 45.
[0039] Once the data is received by personal computer 35, it is
optionally compressed and encrypted by any one of a variety of well
known methods and then sent out over a local or global electronic
network, preferably the Internet, to central monitoring unit 30. It
should be noted that personal computer 35 can be replaced by any
computing device that has access to and that can transmit and
receive data through the electronic network, such as, for example,
a personal digital assistant such as the Palm VII sold by Palm,
Inc., or the Blackberry 2-way pager sold by Research in Motion,
Inc.
[0040] Alternatively, the data collected by sensor device 10, after
being encrypted and, optionally, compressed by microprocessor 20,
may be transferred to wireless device 50, such as a 2-way pager or
cellular phone, for subsequent long distance wireless transmission
to local telco site 55 using a wireless protocol such as e-mail or
as ASCII or binary data. Local telco site 55 includes tower 60 that
receives the wireless transmission from wireless device 50 and
computer 65 connected to tower 60. According to the preferred
embodiment, computer 65 has access to the relevant electronic
network, such as the Internet, and is used to transmit the data
received in the form of the wireless transmission to the central
monitoring unit 30 over the Internet. Although wireless device 50
is shown in FIG. 1 as a discrete device coupled to sensor device
10, it or a device having the same or similar functionality may be
embedded as part of sensor device 10.
[0041] Sensor device 10 may be provided with a button to be used to
time stamp events such as time to bed, wake time, and time of
meals. These time stamps are stored in sensor device 10 and are
uploaded to central monitoring unit 30 with the rest of the data as
described above. The time stamps may include a digitally recorded
voice message that, after being uploaded to central monitoring unit
30, are translated using voice recognition technology into text or
some other information format that can be used by central
monitoring unit 30.
[0042] In addition to using sensor device 10 to automatically
collect physiological data relating to an individual user, a kiosk
could be adapted to collect such data by, for example, weighing the
individual, providing a sensing device similar to sensor device 10
on which an individual places his or her hand or another part of
his or her body, or by scanning the individual's body using, for
example, laser technology or an iStat blood analyzer. The kiosk
would be provided with processing capability as described herein
and access to the relevant electronic network, and would thus be
adapted to send the collected data to the central monitoring unit
30 through the electronic network. A desktop sensing device, again
similar to sensor device 10, on which an individual places his or
her hand or another part of his or her body may also be provided.
For example, such a desktop sensing device could be a blood
pressure monitor in which an individual places his or her arm. An
individual might also wear a ring having a sensor device 10
incorporated therein. A base, not shown, could then be provided
which is adapted to be coupled to the ring. The desktop sensing
device or the base just described may then be coupled to a computer
such as personal computer 35 by means of a physical or short range
wireless connection so that the collected data could be uploaded to
central monitoring unit 30 over the relative electronic network in
the manner described above. A mobile device such as, for example, a
personal digital assistant, might also be provided with a sensor
device 10 incorporated therein. Such a sensor device 10 would be
adapted to collect data when mobile device is placed in proximity
with the individual's body, such as by holding the device in the
palm of one's hand, and upload the collected data to central
monitoring unit 30 in any of the ways described herein.
[0043] Furthermore, in addition to collecting data by automatically
sensing such data in the manners described above, individuals can
also manually provide data relating to various life activities that
is ultimately transferred to and stored at central monitoring unit
30. An individual user can access a web site maintained by central
monitoring unit 30 and can directly input information relating to
life activities by entering text freely, by responding to questions
posed by the web site, or by clicking through dialog boxes provided
by the web site. Central monitoring unit 30 can also be adapted to
periodically send electronic mail messages containing questions
designed to elicit information relating to life activities to
personal computer 35 or to some other device that can receive
electronic mail, such as a personal digital assistant, a pager, or
a cellular phone. The individual would then provide data relating
to life activities to central monitoring unit 30 by responding to
the appropriate electronic mail message with the relevant data.
Central monitoring unit 30 may also be adapted to place a telephone
call to an individual user in which certain questions would be
posed to the individual user. The user could respond to the
questions by entering information using a telephone keypad, or by
voice, in which case conventional voice recognition technology
would be used by central monitoring unit 30 to receive and process
the response. The telephone call may also be initiated by the user,
in which case the user could speak to a person directly or enter
information using the keypad or by voice/voice recognition
technology. Central monitoring unit 30 may also be given access to
a source of information controlled by the user, for example the
user's electronic calendar such as that provided with the Outlook
product sold by Microsoft Corporation of Redmond, Wash., from which
it could automatically collect information. The data relating to
life activities may relate to the eating, sleep, exercise, mind
centering or relaxation, and/or daily living habits, patterns
and/or activities of the individual. Thus, sample questions may
include: What did you have for lunch today? What time did you go to
sleep last night? What time did you wake up this morning? How long
did you run on the treadmill today?
[0044] Feedback may also be provided to a user directly through
sensor device 10 in a visual form, for example through an LED or
LCD or by constructing sensor device 10, at least in part, of a
thermochromatic plastic, in the form of an acoustic signal or in
the form of tactile feedback such as vibration. Such feedback may
be a reminder or an alert to eat a meal or take medication or a
supplement such as a vitamin, to engage in an activity such as
exercise or meditation, or to drink water when a state of
dehydration is detected. Additionally, a reminder or alert can be
issued in the event that a particular physiological parameter such
as ovulation has been detected, a level of calories burned during a
workout has been achieved or a high heart rate or respiration rate
has been encountered.
[0045] As will be apparent to those of skill in the art, it may be
possible to Adownload@ data from central monitoring unit 30 to
sensor device 10. The flow of data in such a download process would
be substantially the reverse of that described above with respect
to the upload of data from sensor device 10. Thus, it is possible
that the firmware of microprocessor 20 of sensor device 10 can be
updated or altered remotely, i.e., the microprocessor can be
reprogrammed, by downloading new firmware to sensor device 10 from
central monitoring unit 30 for such parameters as timing and sample
rates of sensor device 10. Also, the reminders/alerts provided by
sensor device 10 may be set by the user using the web site
maintained by central monitoring unit 30 and subsequently
downloaded to the sensor device 10.
[0046] Referring to FIG. 3, a block diagram of an embodiment of
central monitoring unit 30 is shown. Central monitoring unit 30
includes CSU/DSU 70 which is connected to router 75, the main
function of which is to take data requests or traffic, both
incoming and outgoing, and direct such requests and traffic for
processing or viewing on the web site maintained by central
monitoring unit 30. Connected to router 75 is firewall 80. The main
purpose of firewall 80 is to protect the remainder of central
monitoring unit 30 from unauthorized or malicious intrusions.
Switch 85, connected to firewall 80, is used to direct data flow
between middleware servers 95a through 95c and database server 110.
Load balancer 90 is provided to spread the workload of incoming
requests among the identically configured middleware servers 95a
through 95c. Load balancer 90, a suitable example of which is the
F5 ServerIron product sold by Foundry Networks, Inc. of San Jose,
Calif., analyzes the availability of each middleware server 95a
through 95c, and the amount of system resources being used in each
middleware server 95a through 95c, in order to spread tasks among
them appropriately.
[0047] Central monitoring unit 30 includes network storage device
100, such as a storage area network or SAN, which acts as the
central repository for data. In particular, network storage device
100 comprises a database that stores all data gathered for each
individual user in the manners described above. An example of a
suitable network storage device 100 is the Symmetrix product sold
by EMC Corporation of Hopkinton, Mass. Although only one network
storage device 100 is shown in FIG. 3, it will be understood that
multiple network storage devices of various capacities could be
used depending on the data storage needs of central monitoring unit
30. Central monitoring unit 30 also includes database server 110
which is coupled to network storage device 100. Database server 110
is made up of two main components: a large scale multiprocessor
server and an enterprise type software server component such as the
8/8i component sold by Oracle Corporation of Redwood City, Calif.,
or the 506 7 component sold by Microsoft Corporation of Redmond,
Wash. The primary functions of database server 110 are that of
providing access upon request to the data stored in network storage
device 100, and populating network storage device 100 with new
data. Coupled to network storage device 100 is controller 115,
which typically comprises a desktop personal computer, for managing
the data stored in network storage device 100.
[0048] Middleware servers 95a through 95c, a suitable example of
which is the 220R Dual Processor sold by Sun Microsystems, Inc. of
Palo Alto, Calif., each contain software for generating and
maintaining the corporate or home web page or pages of the web site
maintained by central monitoring unit 30. As is known in the art, a
web page refers to a block or blocks of data available on the
World-Wide Web comprising a file or files written in Hypertext
Markup Language or HTML, and a web site commonly refers to any
computer on the Internet running a World-Wide Web server process.
The corporate or home web page or pages are the opening or landing
web page or pages that are accessible by all members of the general
public that visit the site by using the appropriate uniform
resource locator or URL. As is known in the art, URLs are the form
of address used on the World-Wide Web and provide a standard way of
specifying the location of an object, typically a web page, on the
Internet. Middleware servers 95a through 95c also each contain
software for generating and maintaining the web pages of the web
site of central monitoring unit 30 that can only be accessed by
individuals that register and become members of central monitoring
unit 30. The member users will be those individuals who wish to
have their data stored at central monitoring unit 30. Access by
such member users is controlled using passwords for security
purposes. Preferred embodiments of those web pages are described in
detail below and are generated using collected data that is stored
in the database of network storage device 100.
[0049] Middleware servers 95a through 95c also contain software for
requesting data from and writing data to network storage device 100
through database server 110. When an individual user desires to
initiate a session with the central monitoring unit 30 for the
purpose of entering data into the database of network storage
device 100, viewing his or her data stored in the database of
network storage device 100, or both, the user visits the home web
page of central monitoring unit 30 using a browser program such as
Internet Explorer distributed by Microsoft Corporation of Redmond,
Wash., and logs in as a registered user. Load balancer 90 assigns
the user to one of the middleware servers 95a through 95c,
identified as the chosen middleware server. A user will preferably
be assigned to a chosen middleware server for each entire session.
The chosen middleware server authenticates the user using any one
of many well known methods, to ensure that only the true user is
permitted to access the information in the database. A member user
may also grant access to his or her data to a third party such as a
health care provider or a personal trainer. Each authorized third
party may be given a separate password and may view the member
user's data using a conventional browser. It is therefore possible
for both the user and the third party to be the recipient of the
data.
[0050] When the user is authenticated, the chosen middleware server
requests, through database server 110, the individual user's data
from network storage device 100 for a predetermined time period.
The predetermined time period is preferably thirty days. The
requested data, once received from network storage device 100, is
temporarily stored by the chosen middleware server in cache memory.
The cached data is used by the chosen middleware server as the
basis for presenting information, in the form of web pages, to the
user again through the user's browser. Each middleware server 95a
through 95c is provided with appropriate software for generating
such web pages, including software for manipulating and performing
calculations utilizing the data to put the data in appropriate
format for presentation to the user. Once the user ends his or her
session, the data is discarded from cache. When the user initiates
a new session, the process for obtaining and caching data for that
user as described above is repeated. This caching system thus
ideally requires that only one call to the network storage device
100 be made per session, thereby reducing the traffic that database
server 110 must handle. Should a request from a user during a
particular session require data that is outside of a predetermined
time period of cached data already retrieved, a separate call to
network storage device 100 may be performed by the chosen
middleware server. The predetermined time period should be chosen,
however, such that such additional calls are minimized. Cached data
may also be saved in cache memory so that it can be reused when a
user starts a new session, thus eliminating the need to initiate a
new call to network storage device 100.
[0051] As described in connection with Table 2, the microprocessor
of sensor device 10 may be programmed to derive information
relating to an individual's physiological state based on the data
indicative of one or more physiological parameters. Central
monitoring unit 30, and preferably middleware servers 95a through
95c, may also be similarly programmed to derive such information
based on the data indicative of one or more physiological
parameters.
[0052] It is also contemplated that a user will input additional
data during a session, for example, information relating to the
user's eating or sleeping habits. This additional data is
preferably stored by the chosen middleware server in a cache during
the duration of the user's session. When the user ends the session,
this additional new data stored in a cache is transferred by the
chosen middleware server to database server 110 for population in
network storage device 100. Alternatively, in addition to being
stored in a cache for potential use during a session, the input
data may also be immediately transferred to database server 110 for
population in network storage device 100, as part of a
write-through cache system which is well known in the art.
[0053] Data collected by sensor device 10 shown in FIG. 1 is
periodically uploaded to central monitoring unit 30. Either by long
distance wireless transmission or through personal computer 35, a
connection to central monitoring unit 30 is made through an
electronic network, preferably the Internet. In particular,
connection is made to load balancer 90 through CSU/DSU 70, router
75, firewall 80 and switch 85. Load balancer 90 then chooses one of
the middleware servers 95a through 95c to handle the upload of
data, hereafter called the chosen middleware server. The chosen
middleware server authenticates the user using any one of many well
known methods. If authentication is successful, the data is
uploaded to the chosen middleware server as described above, and is
ultimately transferred to database server 110 for population in the
network storage device 100.
[0054] Referring to FIG. 4, an alternate embodiment of central
monitoring unit 30 is shown. In addition to the elements shown and
described with respect to FIG. 3, the embodiment of the central
monitoring unit 30 shown in FIG. 4 includes a mirror network
storage device 120 which is a redundant backup of network storage
device 100. Coupled to mirror network storage device 120 is
controller 122. Data from network storage device 100 is
periodically copied to mirror network storage device 120 for data
redundancy purposes.
[0055] Third parties such as insurance companies or research
institutions may be given access, possibly for a fee, to certain of
the information stored in mirror network storage device 120.
Preferably, in order to maintain the confidentiality of the
individual users who supply data to central monitoring unit 30,
these third parties are not given access to such user's individual
database records, but rather are only given access to the data
stored in mirror network storage device 120 in aggregate form. Such
third parties may be able to access the information stored in
mirror network storage device 120 through the Internet using a
conventional browser program. Requests from third parties may come
in through CSU/DSU 70, router 75, firewall 80 and switch 85. In the
embodiment shown in FIG. 4, a separate load balancer 130 is
provided for spreading tasks relating to the accessing and
presentation of data from mirror drive array 120 among identically
configured middleware servers 135a through 135c. Middleware servers
135a through 135c each contain software for enabling the third
parties to, using a browser, formulate queries for information from
mirror network storage device 120 through separate database server
125. Middleware servers 135a through 135c also contain software for
presenting the information obtained from mirror network storage
device 120 to the third parties over the Internet in the form of
web pages. In addition, the third parties can choose from a series
of prepared reports that have information packaged along subject
matter lines, such as various demographic categories.
[0056] As will be apparent to one of skill in the art, instead of
giving these third parties access to the backup data stored in
mirror network storage device 120, the third parties may be given
access to the data stored in network storage device 100. Also,
instead of providing load balancer 130 and middleware servers 135a
through 135c, the same functionality, although at a sacrificed
level of performance, could be provided by load balancer 90 and
middleware servers 95a through 95c.
[0057] When an individual user first becomes a registered user or
member, that user completes a detailed survey. The purposes of the
survey are to: identify unique characteristics/circumstances for
each user that they might need to address in order to maximize the
likelihood that they will implement and maintain a healthy
lifestyle as suggested by central monitoring unit 30; gather
baseline data which will be used to set initial goals for the
individual user and facilitate the calculation and display of
certain graphical data output such as the Health Index pistons;
identify unique user characteristics and circumstances that will
help central monitoring unit 30 customize the type of content
provided to the user in the Health Manager's Daily Dose; and
identify unique user characteristics and circumstances that the
Health Manager can guide the user to address as possible barriers
to a healthy lifestyle through the problem-solving function of the
Health Manager.
[0058] The specific information to be surveyed may include: key
individual temperamental characteristics, including activity level,
regularity of eating, sleeping, and bowel habits, initial response
to situations, adaptability, persistence, threshold of
responsiveness, intensity of reaction, and quality of mood; the
user's level of independent functioning, i.e., self-organization
and management, socialization, memory, and academic achievement
skills; the user's ability to focus and sustain attention,
including the user's level of arousal, cognitive tempo, ability to
filter distractions, vigilance, and self-monitoring; the user's
current health status including current weight, height, and blood
pressure, most recent general physician visit, gynecological exam,
and other applicable physician/healthcare contacts, current
medications and supplements, allergies, and a review of current
symptoms and/or health-related behaviors; the user's past health
history, i.e., illnesses/surgeries, family history, and social
stress events, such as divorce or loss of a job, that have required
adjustment by the individual; the user's beliefs, values and
opinions about health priorities, their ability to alter their
behavior and, what might contribute to stress in their life, and
how they manage it; the user's degree of self-awareness, empathy,
empowerment, and self-esteem, and the user's current daily routines
for eating, sleeping, exercise, relaxation and completing
activities of daily living; and the user's perception of the
temperamental characteristics of two key persons in their life, for
example, their spouse, a friend, a co-worker, or their boss, and
whether there are clashes present in their relationships that might
interfere with a healthy lifestyle or contribute to stress.
[0059] Each member user will have access, through the home web page
of central monitoring unit 30, to a series of web pages customized
for that user, referred to as the Health Manager. The opening
Health Manager web page 150 is shown in FIG. 5. The Health Manager
web pages are the main workspace area for the member user. The
Health Manager web pages comprise a utility through which central
monitoring unit 30 provides various types and forms of data,
commonly referred to as analytical status data, to the user that is
generated from the data it collects or generates, namely one or
more of: the data indicative of various physiological parameters
generated by sensor device 10; the data derived from the data
indicative of various physiological parameters; the data indicative
of various contextual parameters generated by sensor device 10; and
the data input by the user. Analytical status data is characterized
by the application of certain utilities or algorithms to convert
one or more of the data indicative of various physiological
parameters generated by sensor device 10, the data derived from the
data indicative of various physiological parameters, the data
indicative of various contextual parameters generated by sensor
device 10, and the data input by the user into calculated health,
wellness and lifestyle indicators. For example, based on data input
by the user relating to the foods he or she has eaten, things such
as calories and amounts of proteins, fats, carbohydrates, and
certain vitamins can be calculated. As another example, skin
temperature, heart rate, respiration rate, heat flow and/or GSR can
be used to provide an indicator to the user of his or her stress
level over a desired time period. As still another example, skin
temperature, heat flow, beat-to-beat heart variability, heart rate,
pulse rate, respiration rate, core temperature, galvanic skin
response, EMG, EEG, EOG, blood pressure, oxygen consumption,
ambient sound and body movement or motion as detected by a device
such as an accelerometer can be used to provide indicators to the
user of his or her sleep patterns over a desired time period.
[0060] Located on the opening Health Manager web page 150 is Health
Index 155. Health Index 155 is a graphical utility used to measure
and provide feedback to member users regarding their performance
and the degree to which they have succeeded in reaching a healthy
daily routine suggested by central monitoring unit 30. Health Index
155 thus provides an indication for the member user to track his or
her progress. Health Index 155 includes six categories relating to
the user's health and lifestyle: Nutrition, Activity Level, Mind
Centering, Sleep, Daily Activities and How You Feel. The Nutrition
category relates to what, when and how much a person eats and
drinks. The Activity Level category relates to how much a person
moves around. The Mind Centering category relates to the quality
and quantity of time a person spends engaging in some activity that
allows the body to achieve a state of profound relaxation while the
mind becomes highly alert and focused. The Sleep category relates
to the quality and quantity of a person's sleep. The Daily
Activities category relates to the daily responsibilities and
health risks people encounter. Finally, the How You Feel category
relates to the general perception that a person has about how they
feel on a particular day. Each category has an associated level
indicator or piston that indicates, preferably on a scale ranging
from poor to excellent, how the user is performing with respect to
that category.
[0061] When each member user completes the initial survey described
above, a profile is generated that provides the user with a summary
of his or her relevant characteristics and life circumstances. A
plan and/or set of goals is provided in the form of a suggested
healthy daily routine. The suggested healthy daily routine may
include any combination of specific suggestions for incorporating
proper nutrition, exercise, mind centering, sleep, and selected
activities of daily living in the user's life. Prototype schedules
may be offered as guides for how these suggested activities can be
incorporated into the user's life. The user may periodically retake
the survey, and based on the results, the items discussed above
will be adjusted accordingly.
[0062] The Nutrition category is calculated from both data input by
the user and sensed by sensor device 10. The data input by the user
comprises the time and duration of breakfast, lunch, dinner and any
snacks, and the foods eaten, the supplements such as vitamins that
are taken, and the water and other liquids consumed during a
relevant, pre-selected time period. Based upon this data and on
stored data relating to known properties of various foods, central
monitoring unit 30 calculates well known nutritional food values
such as calories and amounts of proteins, fats, carbohydrates,
vitamins, etc., consumed.
[0063] The Nutrition Health Index piston level is preferably
determined with respect to the following suggested healthy daily
routine: eat at least three meals; eat a varied diet consisting of
6-11 servings of bread, pasta, cereal, and rice, 2-4 servings
fruit, 3-5 servings of vegetables, 2-3 servings of fish, meat,
poultry, dry beans, eggs, and nuts, and 2-3 servings of milk,
yoghurt and cheese; and drink 8 or more 8 ounce glasses of water.
This routine may be adjusted based on information about the user,
such as sex, age, height and/or weight. Certain nutritional targets
may also be set by the user or for the user, relating to daily
calories, protein, fiber, fat, carbohydrates, and/or water
consumption and percentages of total consumption. Parameters
utilized in the calculation of the relevant piston level include
the number of meals per day, the number of glasses of water, and
the types and amounts of food eaten each day as input by the
user.
[0064] Nutritional information is presented to the user through
nutrition web page 160 as shown in FIG. 6. The preferred
nutritional web page 160 includes nutritional fact charts 165 and
170 which illustrate actual and target nutritional facts,
respectively as pie charts, and nutritional intake charts 175 and
180 which show total actual nutritional intake and target
nutritional intake, respectively as pie charts. Nutritional fact
charts 165 and 170 preferably show a percentage breakdown of items
such as carbohydrates, protein and fat, and nutritional intake
charts 175 and 180 are preferably broken down to show components
such as total and target calories, fat, carbohydrates, protein, and
vitamins. Web page 160 also includes meal and water consumption
tracking 185 with time entries, hyperlinks 190 which allow the user
to directly access nutrition-related news items and articles,
suggestions for refining or improving daily routine with respect to
nutrition and affiliate advertising elsewhere on the network, and
calendar 195 for choosing between views having variable and
selectable time periods. The items shown at 190 may be selected and
customized based on information learned about the individual in the
survey and on their performance as measured by the Health
Index.
[0065] The Activity Level category of Health Index 155 is designed
to help users monitor how and when they move around during the day
and utilizes both data input by the user and data sensed by sensor
device 10. The data input by the user may include details regarding
the user's daily activities, for example the fact that the user
worked at a desk from 8 a.m. to 5 p.m. and then took an aerobics
class from 6 p.m. to 7 p.m. Relevant data sensed by sensor device
10 may include heart rate, movement as sensed by a device such as
an accelerometer, heat flow, respiration rate, calories burned, GSR
and hydration level, which may be derived by sensor device 60 or
central monitoring unit 30. Calories burned may be calculated in a
variety of manners, including: the multiplication of the type of
exercise input by the user by the duration of exercise input by the
user; sensed motion multiplied by time of motion multiplied by a
filter or constant; or sensed heat flux multiplied by time
multiplied by a filter or constant.
[0066] The Activity Level Health Index piston level is preferably
determined with respect to a suggested healthy daily routine that
includes: exercising aerobically for a pre-set time period,
preferably 20 minutes, or engaging in a vigorous lifestyle activity
for a pre-set time period, preferably one hour, and burning at
least a minimum target number of calories, preferably 205 calories,
through the aerobic exercise and/or lifestyle activity. The minimum
target number of calories may be set according to information about
the user, such as sex, age, height and/or weight. Parameters
utilized in the calculation of the relevant piston level include
the amount of time spent exercising aerobically or engaging in a
vigorous lifestyle activity as input by the user and/or sensed by
sensor device 10, and the number of calories burned above
pre-calculated energy expenditure parameters.
[0067] Information regarding the individual user's movement is
presented to the user through activity level web page 200 shown in
FIG. 7, which may include activity graph 205 in the form of a bar
graph, for monitoring the individual user's activities in one of
three categories: high, medium and low intensity with respect to a
pre-selected unit of time. Activity percentage chart 210, in the
form or a pie chart, may also be provided for showing the
percentage of a pre-selected time period, such as one day, that the
user spent in each category. Activity level web page 200 may also
include calorie section 215 for displaying items such as total
calories burned, daily target calories burned, total caloric
intake, and duration of aerobic activity. Finally, activity level
web page 200 may include at least one hyperlink 220 to allow a user
to directly access relevant news items and articles, suggestions
for refining or improving daily routine with respect to activity
level and affiliate advertising elsewhere on the network. Activity
level web page 200 may be viewed in a variety of formats, and may
include user-selectable graphs and charts such as a bar graph, pie
chart, or both, as selectable by Activity level check boxes 225.
Activity level calendar 230 is provided for selecting among views
having variable and selectable time periods. The items shown at 220
may be selected and customized based on information learned about
the individual in the survey and on their performance as measured
by the Health Index.
[0068] The Mind Centering category of Health Index 155 is designed
to help users monitor the parameters relating to time spent
engaging in certain activities which allow the body to achieve a
state of profound relaxation while the mind becomes focused, and is
based upon both data input by the user and data sensed by the
sensor device 10. In particular, a user may input the beginning and
end times of relaxation activities such as yoga or meditation. The
quality of those activities as determined by the depth of a mind
centering event can be measured by monitoring parameters including
skin temperature, heart rate, respiration rate, and heat flow as
sensed by sensor device 10. Percent change in GSR as derived either
by sensor device 10 or central monitoring unit 30 may also be
utilized.
[0069] The Mind Centering Health Index piston level is preferably
calculated with respect to a suggested healthy daily routine that
includes participating each day in an activity that allows the body
to achieve profound relaxation while the mind stays highly focused
for at least fifteen minutes. Parameters utilized in the
calculation of the relevant piston level include the amount of time
spent in a mind centering activity, and the percent change in skin
temperature, heart rate, respiration rate, heat flow or GSR as
sensed by sensor device 10 compared to a baseline which is an
indication of the depth or quality of the mind centering
activity.
[0070] Information regarding the time spent on self-reflection and
relaxation is presented to the user through mind centering web page
250 shown in FIG. 8. For each mind centering activity, referred to
as a session, the preferred mind centering web page 250 includes
the time spent during the session, shown at 255, the target time,
shown at 260, comparison section 265 showing target and actual
depth of mind centering, or focus, and a histogram 270 that shows
the overall level of stress derived from such things as skin
temperature, heart rate, respiration rate, heat flow and/or GSR. In
comparison section 265, the human figure outline showing target
focus is solid, and the human figure outline showing actual focus
ranges from fuzzy to solid depending on the level of focus. The
preferred mind centering web page may also include an indication of
the total time spent on mind centering activities, shown at 275,
hyperlinks 280 which allow the user to directly access relevant
news items and articles, suggestions for refining or improving
daily routine with respect to mind centering and affiliate
advertising, and a calendar 285 for choosing among views having
variable and selectable time periods. The items shown at 280 may be
selected and customized based on information learned about the
individual in the survey and on their performance as measured by
the Health Index.
[0071] The Sleep category of Health Index 155 is designed to help
users monitor their sleep patterns and the quality of their sleep.
It is intended to help users learn about the importance of sleep in
their healthy lifestyle and the relationship of sleep to circadian
rhythms, being the normal daily variations in body functions. The
Sleep category is based upon both data input by the user and data
sensed by sensor device 10. The data input by the user for each
relevant time interval includes the times the user went to sleep
and woke up and a rating of the quality of sleep. As noted in Table
2, the data from sensor device 10 that is relevant includes skin
temperature, heat flow, beat-to-beat heart variability, heart rate,
pulse rate, respiration rate, core temperature, galvanic skin
response, EMG, EEG, EOG, blood pressure, and oxygen consumption.
Also relevant is ambient sound and body movement or motion as
detected by a device such as an accelerometer. This data can then
be used to calculate or derive sleep onset and wake time, sleep
interruptions, and the quality and depth of sleep.
[0072] The Sleep Health Index piston level is determined with
respect to a healthy daily routine including getting a minimum
amount, preferably eight hours, of sleep each night and having a
predictable bed time and wake time. The specific parameters which
determine the piston level calculation include the number of hours
of sleep per night and the bed time and wake time as sensed by
sensor device 10 or as input by the user, and the quality of the
sleep as rated by the user or derived from other data.
[0073] Information regarding sleep is presented to the user through
sleep web page 290 shown in FIG. 9. Sleep web page 290 includes a
sleep duration indicator 295, based on either data from sensor
device 10 or on data input by the user, together with user sleep
time indicator 300 and wake time indicator 305. A quality of sleep
rating 310 input by the user may also be utilized and displayed. If
more than a one day time interval is being displayed on sleep web
page 290, then sleep duration indicator 295 is calculated and
displayed as a cumulative value, and sleep time indicator 300, wake
time indicator 305 and quality of sleep rating 310 are calculated
and illustrated as averages. Sleep web page 290 also includes a
user-selectable sleep graph 315 which calculates and displays one
sleep related parameter over a pre-selected time interval. For
illustrative purposes, FIG. 9 shows heat flow over a one-day
period, which tends to be lower during sleeping hours and higher
during waking hours. From this information, a person's bio-rhythms
can be derived. Sleep graph 315 may also include a graphical
representation of data from an accelerometer incorporated in sensor
device 10 which monitors the movement of the body. The sleep web
page 290 may also include hyperlinks 320 which allow the user to
directly access sleep related news items and articles, suggestions
for refining or improving daily routine with respect to sleep and
affiliate advertising available elsewhere on the network, and a
sleep calendar 325 for choosing a relevant time interval. The items
shown at 320 may be selected and customized based on information
learned about the individual in the survey and on their performance
as measured by the Health Index.
[0074] The Activities of Daily Living category of Health Index 155
is designed to help users monitor certain health and safety related
activities and risks and is based entirely on data input by the
user. The Activities of Daily Living category is divided into four
sub-categories: personal hygiene, which allows the user to monitor
activities such as brushing and flossing his or her teeth and
showering; health maintenance, that tracks whether the user is
taking prescribed medication or supplements and allows the user to
monitor tobacco and alcohol consumption and automobile safety such
as seat belt use; personal time, that allows the user to monitor
time spent socially with family and friends, leisure, and mind
centering activities; and responsibilities, that allows the user to
monitor certain work and financial activities such as paying bills
and household chores.
[0075] The Activities of Daily Living Health Index piston level is
preferably determined with respect to the healthy daily routine
described below. With respect to personal hygiene, the routine
requires that the users shower or bathe each day, brush and floss
teeth each day, and maintain regular bowel habits. With respect to
health maintenance, the routine requires that the user take
medications and vitamins and/or supplements, use a seat belt,
refrain from smoking, drink moderately, and monitor health each day
with the Health Manager. With respect to personal time, the routine
requires the users to spend at least one hour of quality time each
day with family and/or friends, restrict work time to a maximum of
nine hours a day, spend some time on a leisure or play activity
each day, and engage in a mind stimulating activity. With respect
to responsibilities, the routine requires the users to do household
chores, pay bills, be on time for work, and keep appointments. The
piston level is calculated based on the degree to which the user
completes a list of daily activities as determined by information
input by the user.
[0076] Information relating to these activities is presented to the
user through daily activities web page 330 shown in FIG. 10. In
preferred daily activities web page 330, activities chart 335,
selectable for one or more of the sub-categories, shows whether the
user has done what is required by the daily routine. A colored or
shaded box indicates that the user has done the required activity,
and an empty, non-colored or shaded box indicates that the user has
not done the activity. Activities chart 335 can be created and
viewed in selectable time intervals. For illustrative purposes,
FIG. 10 shows the personal hygiene and personal time sub-categories
for a particular week. In addition, daily activities web page 330
may include daily activity hyperlinks 340 which allow the user to
directly access relevant news items and articles, suggestions for
improving or refining daily routine with respect to activities of
daily living and affiliate advertising, and a daily activities
calendar 345 for selecting a relevant time interval. The items
shown at 340 may be selected and customized based on information
learned about the individual in the survey and on their performance
as measured by the Health Index.
[0077] The How You Feel category of Health Index 155 is designed to
allow users to monitor their perception of how they felt on a
particular day, and is based on information, essentially a
subjective rating, that is input directly by the user. A user
provides a rating, preferably on a scale of 1 to 5, with respect to
the following nine subject areas: mental sharpness; emotional and
psychological well being; energy level; ability to cope with life
stresses; appearance; physical well being; self-control;
motivation; and comfort in relating to others. Those ratings are
averaged and used to calculate the relevant piston level.
[0078] Referring to FIG. 11, Health Index web page 350 is shown.
Health Index web page 350 enables users to view the performance of
their Health Index over a user selectable time interval including
any number of consecutive or non-consecutive days. Using Health
Index selector buttons 360, the user can select to view the Health
Index piston levels for one category, or can view a side-by-side
comparison of the Health Index piston levels for two or more
categories. For example, a user might want to just turn on Sleep to
see if their overall sleep rating improved over the previous month,
much in the same way they view the performance of their favorite
stock. Alternatively, Sleep and Activity Level might be
simultaneously displayed in order to compare and evaluate Sleep
ratings with corresponding Activity Level ratings to determine if
any day-to-day correlations exist. Nutrition ratings might be
displayed with How You Feel for a pre-selected time interval to
determine if any correlation exists between daily eating habits and
how they felt during that interval. For illustrative purposes, FIG.
11 illustrates a comparison of Sleep and Activity Level piston
levels for the week of June 10 through June 16. Health Index web
page 350 also includes tracking calculator 365 that displays access
information and statistics such as the total number of days the
user has logged in and used the Health Manager, the percentage of
days the user has used the Health Manager since becoming a
subscriber, and percentage of time the user has used the sensor
device 10 to gather data.
[0079] Referring again to FIG. 5, opening Health Manager web page
150 may include a plurality of user selectable category summaries
156a through 156f, one corresponding to each of the Health Index
155 categories. Each category summary 156a through 156f presents a
pre-selected filtered subset of the data associated with the
corresponding category. Nutrition category summary 156a displays
daily target and actual caloric intake. Activity Level category
summary 156b displays daily target and actual calories burned. Mind
Centering category summary 156c displays target and actual depth of
mind centering or focus. Sleep category summary 156d displays
target sleep, actual sleep, and a sleep quality rating. Daily
Activities category summary 156e displays a target and actual score
based on the percentage of suggested daily activities that are
completed. The How You Feel category summary 156f shows a target
and actual rating for the day.
[0080] Opening Health Manager web page 150 also may include Daily
Dose section 157 which provides, on a daily time interval basis,
information to the user, including, but not limited to, hyperlinks
to news items and articles, commentary and reminders to the user
based on tendencies, such as poor nutritional habits, determined
from the initial survey. The commentary for Daily Dose 157 may, for
example, be a factual statement that drinking 8 glasses of water a
day can reduce the risk of colon cancer by as much as 32%,
accompanied by a suggestion to keep a cup of water by your computer
or on your desk at work and refill often. Opening Health Manager
web page 150 also may include a Problem Solver section 158 that
actively evaluates the user's performance in each of the categories
of Health Index 155 and presents suggestions for improvement. For
example, if the system detects that a user's Sleep levels have been
low, which suggest that the user has been having trouble sleeping,
Problem Solver 158 can provide suggestions for way to improve
sleep. Problem Solver 158 also may include the capability of user
questions regarding improvements in performance. Opening Health
Manager web page 150 may also include a Daily Data section 159 that
launches an input dialog box. The input dialog box facilitates
input by the user of the various data required by the Health
Manager. As is known in the art, data entry may be in the form of
selection from pre-defined lists or general free form text input.
Finally, opening Health Manager web page 150 may include Body Stats
section 161 which may provide information regarding the user's
height, weight, body measurements, body mass index or BMI, and
vital signs such as heart rate, blood pressure or any of the
identified physiological parameters.
[0081] Referring to FIGS. 12-17, a specific embodiment of sensor
device 10 is shown which is in the form of an armband adapted to be
worn by an individual on his or her upper arm, between the shoulder
and the elbow. The specific embodiment of sensor device 10 shown in
FIGS. 12-17 will, for convenience, be referred to as armband sensor
device 400. Armband sensor device 400 includes computer housing
405, flexible wing body 410, and, as shown in FIG. 17, elastic
strap 415. Computer housing 405 and flexible wing body 410 are
preferably made of a flexible urethane material or an elastomeric
material such as rubber or a rubber-silicone blend by a molding
process. Flexible wing body 410 includes first and second wings 418
each having a thru-hole 420 located near the ends 425 thereof.
First and second wings 418 are adapted to wrap around a portion of
the wearer's upper arm.
[0082] Elastic strap 415 is used to removably affix armband sensor
device 400 to the individual's upper arm. As seen in FIG. 17,
bottom surface 426 of elastic strap 415 is provided with velcro
loops 416 along a portion thereof. Each end 427 of elastic strap
415 is provided with velcro hook patch 428 on bottom surface 426
and pull tab 429 on top surface 430. A portion of each pull tab 429
extends beyond the edge of each end 427.
[0083] In order to wear armband sensor device 400, a user inserts
each end 427 of elastic strap 415 into a respective thru-hole 420
of flexible wing body 410. The user then places his arm through the
loop created by elastic strap 415, flexible wing body 410 and
computer housing 405. By pulling each pull tab 429 and engaging
velcro hook patches 428 with velcro loops 416 at a desired position
along bottom surface 426 of elastic strap 415, the user can adjust
elastic strap 415 to fit comfortably. Since velcro hook patches 428
can be engaged with velcro loops 416 at almost any position along
bottom surface 426, armband sensor device 400 can be adjusted to
fit arms of various sizes. Also, elastic strap 415 may be provided
in various lengths to accommodate a wider range of arm sizes. As
will be apparent to one of skill in the art, other means of
fastening and adjusting the size of elastic strap may be used,
including, but not limited to, snaps, buttons, or buckles. It is
also possible to use two elastic straps that fasten by one of
several conventional means including velcro, snaps, buttons,
buckles or the like, or merely a single elastic strap affixed to
wings 418.
[0084] Alternatively, instead of providing thru-holes 420 in wings
418, loops having the shape of the letter D, not shown, may be
attached to ends 425 of wings 418 by one of several conventional
means. For example, a pin, not shown, may be inserted through ends
425, wherein the pin engages each end of each loop. In this
configuration, the D-shaped loops would serve as connecting points
for elastic strap 415, effectively creating a thru-hole between
each end 425 of each wing 418 and each loop.
[0085] As shown in FIG. 18, which is an exploded view of armband
sensor device 400, computer housing 405 includes a top portion 435
and a bottom portion 440. Contained within computer housing 405 are
printed circuit board or PCB 445, rechargeable battery 450,
preferably a lithium ion battery, and vibrating motor 455 for
providing tactile feedback to the wearer, such as those used in
pagers, suitable examples of which are the Model 12342 and 12343
motors sold by MG Motors Ltd. of the United Kingdom.
[0086] Top portion 435 and bottom portion 440 of computer housing
405 sealingly mate along groove 436 into which O-ring 437 is fit,
and may be affixed to one another by screws, not shown, which pass
through screw holes 438a and stiffeners 438b of bottom portion 440
and apertures 439 in PCB 445 and into threaded receiving stiffeners
451 of top portion 435. Alternately, top portion 435 and bottom
portion 440 may be snap fit together or affixed to one another with
an adhesive. Preferably, the assembled computer housing 405 is
sufficiently water resistant to permit armband sensor device 400 to
be worn while swimming without adversely affecting the performance
thereof.
[0087] As can be seen in FIG. 13, bottom portion 440 includes, on a
bottom side thereof, a raised platform 430. Affixed to raised
platform 430 is heat flow or flux sensor 460, a suitable example of
which is the micro-foil heat flux sensor sold by RdF Corporation of
Hudson, N.H. Heat flux sensor 460 functions as a self-generating
thermopile transducer, and preferably includes a carrier made of a
polyamide film. Bottom portion 440 may include on a top side
thereof, that is on a side opposite the side to which heat flux
sensor 460 is affixed, a heat sink, not shown, made of a suitable
metallic material such as aluminum. Also affixed to raised platform
430 are GSR sensors 465, preferably comprising electrodes formed of
a material such as conductive carbonized rubber, gold or stainless
steel. Although two GSR sensors 465 are shown in FIG. 13, it will
be appreciated by one of skill in the art that the number of GSR
sensors 465 and the placement thereof on raised platform 430 can
vary as long as the individual GSR sensors 465, i.e., the
electrodes, are electrically isolated from one another. By being
affixed to raised platform 430, heat flux sensor 460 and GSR
sensors 465 are adapted to be in contact with the wearer's skin
when armband sensor device 400 is worn. Bottom portion 440 of
computer housing 405 may also be provided with a removable and
replaceable soft foam fabric pad, not shown, on a portion of the
surface thereof that does not include raised platform 430 and screw
holes 438a. The soft foam fabric is intended to contact the
wearer's skin and make armband sensor device 400 more comfortable
to wear.
[0088] Electrical coupling between heat flux sensor 460, GSR
sensors 465, and PCB 445 may be accomplished in one of various
known methods. For example, suitable wiring, not shown, may be
molded into bottom portion 440 of computer housing 405 and then
electrically connected, such as by soldering, to appropriate input
locations on PCB 445 and to heat flux sensor 460 and GSR sensors
465. Alternatively, rather than molding wiring into bottom portion
440, thru-holes may be provided in bottom portion 440 through which
appropriate wiring may pass. The thru-holes would preferably be
provided with a water tight seal to maintain the integrity of
computer housing 405.
[0089] Rather than being affixed to raised platform 430 as shown in
FIG. 13, one or both of heat flux sensor 460 and GSR sensors 465
may be affixed to the inner portion 466 of flexible wing body 410
on either or both of wings 418 so as to be in contact with the
wearer's skin when armband sensor device 400 is worn. In such a
configuration, electrical coupling between heat flux sensor 460 and
GSR sensors 465, whichever the case may be, and the PCB 445 may be
accomplished through suitable wiring, not shown, molded into
flexible wing body 410 that passes through one or more thru-holes
in computer housing 405 and that is electrically connected, such as
by soldering, to appropriate input locations on PCB 445. Again, the
thru-holes would preferably be provided with a water tight seal to
maintain the integrity of computer housing 405. Alternatively,
rather than providing thru-holes in computer housing 405 through
which the wiring passes, the wiring may be captured in computer
housing 405 during an overmolding process, described below, and
ultimately soldered to appropriate input locations on PCB 445.
[0090] As shown in FIGS. 12, 16, 17 and 18, computer housing 405
includes a button 470 that is coupled to and adapted to activate a
momentary switch 585 on PCB 445. Button 470 may be used to activate
armband sensor device 400 for use, to mark the time an event
occurred or to request system status information such as battery
level and memory capacity. When button 470 is depressed, momentary
switch 585 closes a circuit and a signal is sent to processing unit
490 on PCB 445. Depending on the time interval for which button 470
is depressed, the generated signal triggers one of the events just
described. Computer housing 405 also includes LEDs 475, which may
be used to indicate battery level or memory capacity or to provide
visual feedback to the wearer. Rather than LEDs 475, computer
housing 405 may also include a liquid crystal display or LCD to
provide battery level, memory capacity or visual feedback
information to the wearer. Battery level, memory capacity or
feedback information may also be given to the user tactily or
audibly.
[0091] Armband sensor device 400 may be adapted to be activated for
use, that is collecting data, when either of GSR sensors 465 or
heat flux sensor 460 senses a particular condition that indicates
that armband sensor device 400 has been placed in contact with the
user's skin. Also, armband sensor device 400 may be adapted to be
activated for use when one or more of heat flux sensor 460, GSR
sensors 465, accelerometer 495 or 550, or any other device in
communication with armband sensor device 400, alone or in
combination, sense a particular condition or conditions that
indicate that the armband sensor device 400 has been placed in
contact with the user's skin for use. At other times, armband
sensor device 400 would be deactivated, thus preserving battery
power.
[0092] Computer housing 405 is adapted to be coupled to a battery
recharger unit 480 shown in FIG. 19 for the purpose of recharging
rechargeable battery 450. Computer housing 405 includes recharger
contacts 485, shown in FIGS. 12, 15, 16 and 17, that are coupled to
rechargeable battery 450. Recharger contracts 485 may be made of a
material such as brass, gold or stainless steel, and are adapted to
mate with and be electrically coupled to electrical contacts, not
shown, provided in battery recharger unit 480 when armband sensor
device 400 is placed therein. The electrical contacts provided in
battery recharger unit 480 may be coupled to recharging circuit
481a provided inside battery recharger unit 480. In this
configuration, recharging circuit 481 would be coupled to a wall
outlet, such as by way of wiring including a suitable plug that is
attached or is attachable to battery recharger unit 480.
Alternatively, electrical contacts 480 may be coupled to wiring
that is attached to or is attachable to battery recharger unit 480
that in turn is coupled to recharging circuit 481b external to
battery recharger unit 480. The wiring in this configuration would
also include a plug, not shown, adapted to be plugged into a
conventional wall outlet.
[0093] Also provided inside battery recharger unit 480 is RF
transceiver 483 adapted to receive signals from and transmit
signals to RF transceiver 565 provided in computer housing 405 and
shown in FIG. 20. RF transceiver 483 is adapted to be coupled, for
example by a suitable cable, to a serial port, such as an RS 232
port or a USB port, of a device such as personal computer 35 shown
in FIG. 1. Thus, data may be uploaded from and downloaded to
armband sensor device 400 using RF transceiver 483 and RF
transceiver 565. It will be appreciated that although RF
transceivers 483 and 565 are shown in FIGS. 19 and 20, other forms
of wireless transceivers may be used, such as infrared
transceivers. Alternatively, computer housing 405 may be provided
with additional electrical contacts, not shown, that would be
adapted to mate with and be electrically coupled to additional
electrical contacts, not shown, provided in battery recharger unit
480 when armband sensor device 400 is placed therein. The
additional electrical contacts in the computer housing 405 would be
coupled to the processing unit 490 and the additional electrical
contacts provided in battery recharger unit 480 would be coupled to
a suitable cable that in turn would be coupled to a serial port,
such as an RS R32 port or a USB port, of a device such as personal
computer 35. This configuration thus provides an alternate method
for uploading of data from and downloading of data to armband
sensor device 400 using a physical connection.
[0094] FIG. 20 is a schematic diagram that shows the system
architecture of armband sensor device 400, and in particular each
of the components that is either on or coupled to PCB 445.
[0095] As shown in FIG. 17, PCB 445 includes processing unit 490,
which may be a microprocessor, a microcontroller, or any other
processing device that can be adapted to perform the functionality
described herein. Processing unit 490 is adapted to provide all of
the functionality described in connection with microprocessor 20
shown in FIG. 2. A suitable example of processing unit 490 is the
Dragonball EZ sold by Motorola, Inc. of Schaumburg, Ill. PCB 445
also has thereon a two-axis accelerometer 495, a suitable example
of which is the Model ADXL210 accelerometer sold by Analog Devices,
Inc. of Norwood, Mass. Two-axis accelerometer 495 is preferably
mounted on PCB 445 at an angle such that its sensing axes are
offset at an angle substantially equal to 45 degrees from the
longitudinal axis of PCB 445 and thus the longitudinal axis of the
wearer's arm when armband sensor device 400 is worn. The
longitudinal axis of the wearer's arm refers to the axis defined by
a straight line drawn from the wearer's shoulder to the wearer's
elbow. The output signals of two-axis accelerometer 495 are passed
through buffers 500 and input into analog to digital converter 505
that in turn is coupled to processing unit 490. GSR sensors 465 are
coupled to amplifier 510 on PCB 445. Amplifier 510 provides
amplification and low pass filtering functionality, a suitable
example of which is the Model AD8544 amplifier sold by Analog
Devices, Inc. of Norwood, Mass. The amplified and filtered signal
output by amplifier 510 is input into amp/offset 515 to provide
further gain and to remove any bias voltage and into
filter/conditioning circuit 520, which in turn are each coupled to
analog to digital converter 505. Heat flux sensor 460 is coupled to
differential input amplifier 525, such as the Model INA amplifier
sold by Burr-Brown Corporation of Tucson, Ariz., and the resulting
amplified signal is passed through filter circuit 530, buffer 535
and amplifier 540 before being input to analog to digital converter
505. Amplifier 540 is configured to provide further gain and low
pass filtering, a suitable example of which is the Model AD8544
amplifier sold by Analog Devices, Inc. of Norwood, Mass. PCB 445
also includes thereon a battery monitor 545 that monitors the
remaining power level of rechargeable battery 450. Battery monitor
545 preferably comprises a voltage divider with a low pass filter
to provide average battery voltage. When a user depresses button
470 in the manner adapted for requesting battery level, processing
unit 490 checks the output of battery monitor 545 and provides an
indication thereof to the user, preferably through LEDs 475, but
also possibly through vibrating motor 455 or ringer 575. An LCD may
also be used.
[0096] PCB 445 may include three-axis accelerometer 550 instead of
or in addition to two-axis accelerometer 495. The three-axis
accelerometer outputs a signal to processing unit 490. A suitable
example of three-axis accelerometer is the .mu.PAM product sold by
I.M. Systems, Inc. of Scottsdale, Ariz. Three-axis accelerometer
550 is preferably tilted in the manner described with respect to
two-axis accelerometer 495.
[0097] PCB 445 also includes RF receiver 555 that is coupled to
processing unit 490. RF receiver 555 may be used to receive signals
that are output by another device capable of wireless transmission,
shown in FIG. 20 as wireless device 558, worn by or located near
the individual wearing armband sensor device 400. Located near as
used herein means within the transmission range of wireless device
558. For example, wireless device 558 may be a chest mounted heart
rate monitor such as the Tempo product sold by Polar Electro of
Oulu, Finland. Using such a heart rate monitor, data indicative of
the wearer's heart rate can be collected by armband sensor device
400. Antenna 560 and RF transceiver 565 are coupled to processing
unit 490 and are provided for purposes of uploading data to central
monitoring unit 30 and receiving data downloaded from central
monitoring unit 30. RF transceiver 565 and RF receiver 555 may, for
example, employ Bluetooth technology as the wireless transmission
protocol. Also, other forms of wireless transmission may be used,
such as infrared transmission.
[0098] Vibrating motor 455 is coupled to processing unit 490
through vibrator driver 570 and provides tactile feedback to the
wearer. Similarly, ringer 575, a suitable example of which is the
Model SMT916A ringer sold by Projects Unlimited, Inc. of Dayton,
Ohio, is coupled to processing unit 490 through ringer driver 580,
a suitable example of which is the Model MMBTA14 CTI darlington
transistor driver sold by Motorola, Inc. of Schaumburg, Ill., and
provides audible feedback to the wearer. Feedback may include, for
example, celebratory, cautionary and other threshold or event
driven messages, such as when a wearer reaches a level of calories
burned during a workout.
[0099] Also provided on PCB 445 and coupled to processing unit 490
is momentary switch 585. Momentary switch 585 is also coupled to
button 470 for activating momentary switch 585. LEDs 475, used to
provide various types of feedback information to the wearer, are
coupled to processing unit 490 through LED latch/driver 590.
[0100] Oscillator 595 is provided on PCB 445 and supplies the
system clock to processing unit 490. Reset circuit 600, accessible
and triggerable through a pin-hole in the side of computer housing
405, is coupled to processing unit 490 and enables processing unit
490 to be reset to a standard initial setting.
[0101] Rechargeable battery 450, which is the main power source for
the armband sensor device 400, is coupled to processing unit 490
through voltage regulator 605. Finally, memory functionality is
provided for armband sensor device 400 by SRAM 610, which stores
data relating to the wearer of armband sensor device 400, and flash
memory 615, which stores program and configuration data, provided
on PCB 445. SRAM 610 and flash memory 615 are coupled to processing
unit 490 and each preferably have at least 512 K of memory.
[0102] In manufacturing and assembling armband sensor device 400,
top portion 435 of computer housing 405 is preferably formed first,
such as by a conventional molding process, and flexible wing body
410 is then overmolded on top of top portion 435. That is, top
portion 435 is placed into an appropriately shaped mold, i.e., one
that, when top portion 435 is placed therein, has a remaining
cavity shaped according to the desired shape of flexible wing body
410, and flexible wing body 410 is molded on top of top portion
435. As a result, flexible wing body 410 and top portion 435 will
merge or bond together, forming a single unit. Alternatively, top
portion 435 of computer housing 405 and flexible wing body 410 may
be formed together, such as by molding in a single mold, to form a
single unit. The single unit however formed may then be turned over
such that the underside of top portion 435 is facing upwards, and
the contents of computer housing 405 can be placed into top portion
435, and top portion 435 and bottom portion 440 can be affixed to
one another. As still another alternative, flexible wing body 410
may be separately formed, such as by a conventional molding
process, and computer housing 405, and in particular top portion
435 of computer housing 405, may be affixed to flexible wing body
410 by one of several known methods, such as by an adhesive, by
snap-fitting, or by screwing the two pieces together. Then, the
