Blue Wtpl Polygraph Machine With 4 Sensors

Description:

It is a great product that was developed by Polygraph experts, which has adopted the newest and advanced technologies in the polygraph industry.

It contains data acquisition hardware inside a plastic box and firmware embedded software for reading and decoding biological signals from the human body. The firmware transmits the signals and analysis to a windows PC or Android mobile. This hardware reads data from 6 different sensor as a real-time values with the transmission rate of 2400 bytes per second.

When you connect the hardware to the Android device you need to use OTG USB cable. Each machine has its own serial numbers inside the hardware, preventing the possibility of faking the product. When using the machine for the first time, the user need to activate the hardware from his PC.

Functions and Features:

There are 4 different physiological bio signals sensors, which reads the human body signals, do analysis of the psycho physiology parameters as follows:
1. The blood volume capacity in the finger AcA A BVP (blood volume pulse amplitude that reflects the human fear level)
2. HR heart rate and IBI (Inter Beat Interval in MSEC, increasing the pace - measure pressure and stress - fight or flight syndrome).
3. Dynamically relative blood pressure changes that measures even very small changes of the BP that indicates fear, stress, pressure, fight or flight, etc .
4. HRV (Heart Rate Variability) time domain calculation and FFT spectrum analysis that provides 40 different psychophysiology and physiological indicators concerning mental and emotional state of the autonomic nervous system activity. The most 4 common parameters are: "Rumination thoughts" (VLF), "Stress activation" (HF), "relax activation" (LF), "calm ratio" (LF/HF).

The GSR sensor: Measuring the human galvanic Skin Response with 2 electrodes that connected to 2 fingers (2 and 4) for the inspection of the sympathetic autonomic nervous system activity. The electric circuit is extremely sensitive and show values between 2000 to 60,000 in a very high-resolution measurements.

The Temperature Sensor: Measuring the peripheral skin temperature in 0.01 C resolution, when the skin temperature become lower - this is indicator for the general sympathetic nerve system state.

The Abdominal breathing sensor: A very sensitive stretch sensor based on rubber that measures the human abdominal breathing amplitude.

PC Software

The PC software of the machine enables the customer to run a professional polygraph test - very simple to use - very sophisticated technology include updating sequential questions (cold questions, hot questions and control question).
The tester can update during running the test any kind of surround or background or inside artifacts that influence the recorded signals and that's include the "artifacts timing" signed with a specific background color to indicate the situation.
