Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application is a continuation of U.S. application Ser.
No. 11/436,769, filed on May 19, 2006, which claims the benefit of
Korean Patent Application No. 10-2005-0095644, filed on Oct. 11,
2005, in the Korean Intellectual Property Office, the disclosures
of which are incorporated herein by reference.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to a health care technology
for measuring and monitoring a change in a body, and more
particularly, relates to accessories placed on a body of a user to
measure a change in the body of the user or condition of the user
and communicate with an external apparatus.
[0004] 2. Description of Related Art
[0005] A ubiquitous system indicates an information communication
environment in which a user is unaware of a network or a computer
and whose position is irrelevant while the user freely access the
network. When a ubiquitous system is generally used, every one can
use information technology in varied embodiments. Thus, a user
could, for example, not only use such technology in a house or
vehicle but also on the top of a mountain. Also, since the general
use of a ubiquitous system increases the number of users of
computers connected to a network, the information technology
industry may be also expanded to a size and range in relation to
the number of the users. Due to merits of not only portability and
convenience, as described above, but also accessing a network in
which time and position are irrelevant, technologies associated
with Ubiquitous system are being developed in nations
worldwide.
[0006] The described technologies associated with ubiquitous
systems may be applied in every field of human life, and currently,
in particular, due to the well-being fad, a ubiquitous healthcare
(U-healthcare) is in the spotlight as a notable technical field.
U-healthcare is a ubiquitous technology in which a chip or sensor
associated with medical services is integrated into any part of
human life, thereby naturally providing medical services to
everyone at anytime and anywhere. According to the U-healthcare,
medical treatments performed in only hospitals, such as various
medical examinations, management of diseases, emergency care, and
consulting with doctors, may be realized during everyday life.
[0007] As a result, a device capable of measuring or monitoring a
change in a body or a peripheral environment may be required. Also,
according to development of a technology associated with integrated
circuits (IC), a circuit capable of performing desired functions
may be embodied in one chip. Accordingly, according to the level of
present technology, the size of a circuit unit may be minimized to
several mm or less.
[0008] Also, since technology associated with antennas is
continuously developed, the size of an antenna may be minimized.
Generally, a small device including wireless communication function
may employ a monopole antenna because the monopole antenna having a
quarter (1/4) length of a wavelength of a used frequency may
perform efficient communication function. Also, recently, greater
minimization of antennas has been made possible by employment of
dielectric material or improvement of technology of antenna
patterns. For example, when a monopole antenna is used for a
frequency of approximately 2.45 GHz, a required length of the
antenna is approximately 3 cm, and when a dielectric material or a
particular pattern is used, the size of the antenna may be
manufactured to be less than approximately 1 cm.
[0009] When a device for monitoring a change in a body or
environments is placed on a body, a functional circuit and antenna
may be minimized to a desired size. However, a ground has to have a
length of 1/4 wavelength, and when a monopole antenna is used in a
frequency band of approximately 2.45 GHz, a required length of a
ground has to be at least approximately 3 cm.
[0010] Accordingly, to manufacture a monitoring device placed on a
body in a small size, since a ground of a certain length is
required, there are many restrictions to manufacture the monitoring
device in a micro size. Actually, when a ground is formed on a
printed circuit board (PCB), as the entire size of the PCB is
reduced, an area in which the ground is formed is also reduced and
the antenna cannot perform its function.
BRIEF SUMMARY
[0011] An aspect of the present invention provides accessories
capable of containing a circuit unit and an antenna formed in a
small size and effectively providing a ground greater than a
certain length.
[0012] An aspect of the present invention also provides accessories
capable of being usually placed on or easily carried by using
conventional small articles or accessories.
[0013] According to an aspect of the present invention, there is
provided an accessory including a body capable of being placed on a
human body; a measurement unit installed in the body measuring a
change in surroundings; a signal processing unit processing a
signal acquired from the measurement unit; and a wireless
communication unit including a monopole antenna transmitting the
signal processed by the signal processing unit and a ground
installed along the body, corresponding to the monopole
antenna.
[0014] Due to development of technology, the signal processing unit
or the monopole antenna may be manufactured smaller than 1 cm.
However, the ground may be required to be greater than a certain
length because of resonance. Accordingly, the ground may be
separately connected to a PCB substrate and wired along the
accessories body, thereby manufacturing a minimized monitoring
device.
[0015] The accessory may be an accessory or small article which can
be placed on a human body or clothes. In detail, they may be
accessories formed in the shape of a ring or other ornaments such
as a necklace, a bracelet, a necktie pin and the like, and they may
be small articles formed in the shape of a ring or band such as a
hat, a watch, a band, a waist belt, glasses and the like. The
measuring unit may be directly or indirectly in contact with the
body of the user to measure an ECG, an EMG, an EEG, a GSR, a body
temperature, a pulse, and a blood pressure. In addition, the
measurement unit may sense temperature, pressure, humidity,
components of air, composition of air, radioactivity, and
deleterious bacteria of peripheral environments.
[0016] The signal processing unit for processing the measured
signal may be embodied as an IC chip on the PCB substrate, and the
monopole antenna may be embodied on the same. Also, the monopole
antenna may be manufactured to be less than .lamda./4 by using high
dielectric material or embodying a precision antenna pattern.
[0017] According to another aspect of the present invention, there
is provided an accessory for remote monitoring, including: a body
capable of being placed on an object; a measurement unit installed
in the body measuring a change in a surrounding environment; a
circuit unit including an integrated circuit chip processing a
signal acquired from the measurement unit and a monopole antenna
formed on the same substrate on which the integrated circuit chip
is installed; and a ground connected to the circuit unit and
extended along the body.
[0018] According to another aspect of the present invention, there
is provided a method of remote monitoring, including: placing a
body on the object; measuring a change in a surrounding state via a
measurement unit installed in the body; processing, via a signal
processing unit, a signal acquired from the measurement unit; and
transmitting the signal processed by the signal processing unit via
a wireless communication unit including a monopole antenna and a
ground installed along the body and corresponding to the monopole
antenna.
[0019] Additional and/or other aspects and advantages of the
present invention will be set forth in part in the description
which follows and, in part, will be obvious from the description,
or may be learned by practice of the invention.

figures.
[0030] FIG. 1 is a perspective view illustrating an accessory
according to an embodiment of the present invention, FIG. 2 is a
partial enlarged front view illustrating internal elements of the
accessory of FIG. 1, and FIG. 3 is a partial enlarged
cross-sectional view illustrating the internal elements of the
accessory of FIG. 1.
[0031] Referring to FIGS. 1 through 3, accessory 100 is a kind of
necklace. Accordingly, the accessory 100 comprises an accessory
body 110 in the shape of a necklace, a measurement unit 120 mounted
on the accessory body 110, an IC chip 132 including a signal
processing circuit, a monopole antenna 142, and a ground 144. A
part of the measurement unit 120 is exposed outward to be capable
of maintaining contact with the body of the user directly or
indirectly.
[0032] The accessory body 110 is in the form of a general necklace
and includes a pendant 112 and a necklace string 114. The
measurement unit 120 that can be attached to the body is mounted on
the rear side of the pendant 112, the IC chip 132 and the monopole
antenna 142 are mounted on a printed circuit board (PCB) substrate
130 in the pendant 112.
[0033] The top of the pendant 112 is connected to the necklace
string 114, and the monopole antenna 142 and the ground 144 are
electrically connected via the engaged parts of the pendant 112 and
the necklace string 114. The ground 144 is built into and along the
necklace string 114 and is formed in a length of more than
approximately .lamda./4, where the symbol of .lamda. indicates a
wavelength of a used frequency. Accordingly, the IC chip 132 may
form a wireless communication unit by using the monopole antenna
142, and the ground 144 may function as a valid image antenna with
respect to the monopole antenna 142.
[0034] The measurement unit 120 installed in the pendant 112 may
receive a signal for monitoring a biosignal of the user by being in
contact with the body of the user. Generally, the biosignal may
include an electrocardiogram, an electromyogram, an
electroencephalogram, and a galvanic skin response. The measurement
unit may be also used for measuring a body temperature, a pulse, or
a blood pressure. In addition, the measurement unit 120 may further

characteristics instead of physiological characteristics, the
measurement unit may be mounted on the front of a pendant instead
of the rear of the pendant.
[0035] In the present embodiment, though the measurement unit 120
includes one contact terminal, according to the type and number of
biosignals to be measured, two or more contact terminals may be
provided and positions of contact terminals may be determined. When
a plurality of contact terminals are formed, each of the contact
terminals is independently connected to the signal processing unit,
and the signal processing unit may generate a signal to be
transmitted to the wireless communication unit via a process of
amplifying, filtering, or combining signals transmitted from each
of the terminals.
[0036] FIG. 4 is a partial enlarged front view illustrating

elements of FIG. 4.
[0037] Referring to FIGS. 1-5, the measurement unit 120 disposed in
the rear side of the pendant may be in continuous contact with the
body of the user and may measure electrocardiogram or
electromyogram. A signal measured by the measurement unit 120 may
be an analog signal. The IC chip 132, as a signal processing unit,
receives the analog signal from the measurement unit 120 and may
process the received signal to transmit to an external apparatus or
server. Generally, the IC chip 132 may amplify, filter, and convert
the measured signal into a digital signal, and the processed signal
may be transmitted to an external apparatus or server via the
wireless communication unit 140.
[0038] In the present embodiment, it is described that the
accessory 100 measures a biosignal and transmits the biosignal to
the external apparatus or server. However, the accessory 100 may
receive emergency information from the external apparatus or server
and may display the degree of the danger for giving a warning to
the user. Namely, the wireless communication unit 140 may include
not only a function of transmission but also a function of
reception.

body temperature, a pulse, and a blood pressure of a user while
being in contact with the head. Though the measurement unit 420 is
mounted in one of the glasses legs 414 in the present embodiment,
according to the type and number of biosignals to be measured, two
or more measurement units may be provided in each glasses leg.
[0059] The measurement unit 420 in the glasses leg 414 may measure
a desired biosignal while being in contact with the head. A signal
measured by the measurement unit 420 is processed via the IC chip
of the signal processing unit 430, and the processed signal may be
transmitted to an external apparatus or server by using the
monopole antenna and the ground 444.
[0060] The accessories of the above-described embodiments of the
present invention may be conventional accessories or small articles
and may include a micro circuit unit and an antenna. However, since
a ground has to have a certain length for effective communication,
the ground may be built or wired into an accessory body in the
certain length. A ground having more than the certain length makes
an efficient wireless communication of the accessory possible.
[0061] Since the shapes of conventional clothing articles or
accessory can be used as an accessory body of the present
invention, it is simple to put on or carry, thereby maximizing
convenience of users.
[0062] Although a few embodiments of the present invention have
been shown and described, the present invention is not limited to
the described embodiments. Instead, it would be appreciated by
those skilled in the art that changes may be made to these
embodiments without departing from the principles and spirit of the
invention, the scope of which is defined by the claims and their
equivalents.
