FIRST PROJECT
Properties
of Home-care program using the wireless
ECG module
---- Determination (in terms of normal
or abnormal
ECG waveforms) of ECG waveform abnormalities by a neural network,
----
Learning the normal ECG waveform of the user (patient)
----
Determination and monitoring of abnormal rhythms (bradicardia,
tachicardia, asistol,
escape beat, premature ventricular contraction (PVC), T on R, bigemini,
trigemini, rarely PVC, atrial premature beat (APB),
----
Monitoring the standard limb leads I and II,
----
If needed, abnormal/normal ECG
data is saved in hard-disk, or read from the disk to monitor ECG data,
----
If needed, abnormal/normal ECG
data is sent to a computer on internet,
----
Configuration of the internet address of server/client computer, virtual serial
port number, etc.,
----
Handling connection/disconnection
of bluetooth communication
----
Compatible with Win98 & XP Operating System

escape beat, premature ventricular contraction (PVC), T on R, bigemini, trigemini, rarely PVC, atrial premature beat (APB),
----
Monitoring the standard limb leads I ,
----
Continue or if needed, abnormal/normal ECG
data is saved in MMC card, or read from the MMC card to monitor ECG data,
----
Continue or if needed, abnormal/normal ECG
data is sent to a computer (any IP or Port) on internet by GPRS,
----
Configuration of the internet address of server/client computer, virtual serial
port number, etc.,
----
Handling connection/disconnection
of bluetooth communication
----
Compatible with Symbean OP (for Nokia 6600).

THIRD PROJECT
Technical specifations of a
New Wireless ECG module
---- Continuous ECG data transmission from
standard limb lead (lead I ),
---- 300Hz sampling
frequency,
---- ECG data is saved
into a MMC Card (32 Mbyte) in real-time,
---- For Supply voltage 3.3V,
total current < 25
mA for the
module with bluetooth,
total current < 8.5
mA for the
module without bluetooth,
---- 26 hours
usage with 1.5 Li-ion battery
(2400 mA ) for the module with
bluetooth,
---- Size of the
module is 60´20´10 mm,
---- Modul
includes micro-controler with 12 bit ADC,
---- Modul
includes buzzer for alerting open
lead wires
---- Modul
can send ECG signal to the PC via
RS232 connection without bluetooth and
MMC card,
---- the cost of the module
is
less than 15 € (Euro) without bluetooth and MMC card.
