Researcher Katsigiannis of the Greek Research and Technology Center (CERTH) and researcher Hatziyannaki of Patras Computer Technology Institute recently developed a new type of recording electronic card that can be used to manufacture ultra-small Holter electrocardiograph (Holter). The new dynamic electrocardiograph developed according to this technology will have many outstanding advantages. It is not only small in size, light in weight, consumes very little power, but also has excellent signal quality, and has good fidelity and wireless sensing functions. It will have a GPS function, which can automatically alert the medical team or doctor immediately via a Wi-Fi mobile phone or PC wireless communication device. When detecting heart rhythm, it only captures abnormal heart rhythm instead of normal heart rate. The instrument weighs only 90 grams, easy to carry, does not affect the patient's activities. Without a monitor and printer, the acquired ECG can be connected to any computer via USB for reading, storage, processing, or sending to another doctor or medical center.

Researchers say the next goal is to find ways to improve battery life so that patients can carry it for more than a week, determine the geographic coordinates of patients and doctors at any time, and send arrhythmia records in real time. It will become a truly innovative product that provides patients with permanent monitoring of heart disease.

RJ45 Keystone Jack

A keystone jack is a standardized snap-in package for mounting a variety of low-voltage electrical jacks or optical connectors into a keystone wall plate, face plate, surface-mount box, or a patch panel.

Many types of jacks are available in the keystone module format, limited mainly by their physical size, including:


6P6C (RJ-11) modular jacks (telephone)
8P8C (RJ-45) modular jacks (computer networking)
F connector (TV antenna/cable/satellite)

RCA jacks (audio/video)
4-pin mini-DIN (S-Video jacks)
HDMI jacks (high-definition video and audio)
Optical fiber connectors
BNC connector
With compact size, integral shutter, keystone mounting format a, our keystone Jack for voice and Category 5e and 6A ensure a smart, reliable installation. All copper conductors are plated with gold. The 8 pins of RJ45 tool-less keystone jack are effortlessly terminated in one simple operation resulting in reliable interconnection in record time. The jacks can be reused several times if a wiring mistake is made.

What's more,we can also supply you blank patch panel, face plate and surface mount box to use together with our modular jacks.
