Computerized Polygraph

The Computerized Polygraph Machine is a cutting-edge lie detection system that records physiological responses such as heart rate, respiration, and skin conductance to assess truthfulness. It is widely used in forensic investigations, law enforcement, and psychological research.

Developed by highly qualified technocrats having a rich experience of 25 years in Bio-medical instrumentation. Already manufacturing EEG, EMG, ECG, ECT, ENG, BIO-FEEDBACK "BIOTRAINERS" POLYGRAPH, STUDENT PHSIOGRAPH and many more. Having more than 5000 satisfied users in the field of Neurology, Psychology, Psychiatry, Cardiology, Physiology and Pharmacology.

LESSIONS

• ELECTROENCEPHALOGRAM (EEG): Record and View EEG from any location. See how EFG signal changes in Relaxation, Attention and use filters to examine frequency band (Alpha, Beta, Delta & Theta).
• MUSCLE CONTRACTION (EMG): Record & View the EMG Signal with surface electrodes from different location. See raw and with integrated real time EMG data. Simultaneously Compare the EMG signal from one muscle group to another. Study isometric and Isotonic muscle loading tasks.
• ELECTROCARDIOGRAM (ECG): Record & View ECG leads I, II, III, AVR, aVL, AVF & Chest. Study Finthoven Law. Perform measurements of P,Q,R,S and T Waves. Measure amplitude and timing of waves and calculate BPM. Study realtime ECG and BPM.
  
• ENG: Record & view vertical and horizontal eye movement. Perform Saccade and Gaze Test. See a graph for vertical motions and for horizontal motions. A complete X/Y tracing of where subject looked during the test period is recorded.
  
• PULSE & PLETHYSMOGRAPHY: Pulse is measured at the fingertip non-invasively sensing variations in blood density. Examine the relationship between ECG and PULSE. Study mechanical action of the heart.
• RESPIRATION: Record and view Respiratory efforts and relative air flow Respiration is measured by recording chest expansion and contraction. Air flow is indirectly recorded by using a thermister placed next to the nose. Examine the time relationship between chest motion and air flow.
• POLYGRAPH: Record and view the standard Polygraph measurements e.g. Respiration, Galvanic Skin Response and Pulse rate. The timing of each question is recorded by a marker on the graph. Study Physiological Changes on telling (or not telling) the truth. Any four parameters can be recorded simultaneously.
• REACTION TIME: Auditory "Click" stimulation is given to subject and the subject responses by pressing a pushbutton. Auditory stimulations are given in two modes random and non random fashion.
• BIOFEEDBACK: Record and view Heart Rate (BPM) and GSR. Control the X/Y position of a dot, by influencing subject's BPM or GSR. If the heart rate beats faster, the dot moves up, if slower, the dot moves downward. If subject perspire more (decrease in Resistance) the dot moves to left incase in resistance, dot moves to the right.
• SPIROMETERY: Pulmonary Function Testing Capable of performing tests:-

1. Forced Vital Capacity
2. Slow Vital Capacity
3. Maximum Voluntary Ventilation

• HEART SOUNDS: Record and view Phono cardiogram. Examine relationship between Pulse and Phonocardiogram.
• AMPHIBIAN EXPERIMENTS: Amphibian experiments like signal Muscle twitch, after load and free load contractions, strength of Stimuli, Tetanus, fatigue, Isometric contraction etc. are performed using Isotonic and Isometric Force Transducer.
