Dipha - 1

Dipha One – Amplifier – Multiple Uses Dipha® is the first of a new class of data acquisition systems opening the digital world for electrophysiology. Dipha® is based on a new concept for the collection and transmission of signals: one amplifier for multiple uses. Data acquisition and pre-processing takes place in a light weight, smartphone sized, battery powered amplifier. Measurement data is transmitted with low power from the Dipha® amplifier to a transceiver USB dongle connected to a Personal Computer or Notebook placed at a distance of up to 10 meters. The connector header contains a chip with a unique application specific number that is broadcast when the electrode head is placed on the amplifier. A computer, licensed to recognize the assembly number, automatically makes contact with the Dipha® amplifier. A docking station serves as battery charger and as traveling case for the Dipha® ampl

Dipha® amplifier MEASUREMENT SYSTEM The Dipha® amplifier contains a Digital Reference Amplifier with 16 measurement channels. The true DC Digital Reference Amplifier has especially been designed for the measurement of sensitive electro-physiological signals. Extremely high input impedances and very low input noise currents enable high quality measurements even with electrode impedances being more than 10 times higher as in common practice. The upper trace shows cable movement artefacts from uncoated shielded cables. During the same test coated shielded cables show a small EMG signal and no...

THE APPLICATION The application has the look and feel suited to the professional user and not to the biomedical engineer or software developer so the user is focused on the patient and not on the computer screen. The general idea is that Dipha® applications should give answers on simple formulated questions about physiological parameters measured by electro-physiological means. Applications therefore start at the result end of measurements in the form of a report containing information ranging from a single number to tables and figures. All known tools and activities leading to this report...
