LXCAT

What is it?

The LXCAT is a next generation field-deployable rapid use preliminary credibility assessment system. It records and analyzes physiologic responses that are well-known to correlate with truth telling and deception. It does so by transmitting data to a laptop or tablet using a new and improved credibility assessment software. The LXCAT is an expedient method for screening individuals through use of a highly standardized testing protocol and structure. The software includes automated scoing and report functions, alleviating, or minimizing, the user from introducing subjectivity into the test result decision.

How does it work?

The LXCAT records and analyzes physiological responses to pre-reviewed questions. Electrodes are attached to two fingertips (or stuck to the palm) to measure changes in electrical conductivity of the skin and a photo-plethysmograph (pulse oximeter) is clipped onto a fingertip to measure blood volume and the interval between heartbeats. The system converts the analog signals to digital then transmits them to a tablet or laptop.

Device

The ruggedized housing features medical grade electrical isolation, high-quality ruggedized quick release (IP62 rated) component connectors that are dustproof and have a high mating cycle. The unit is small, portable and housed in a watertight, crushproof and dust proof carrying case. Only requiring EDA and Vasomotor sensors, the system requires reduced professional training for test administration.

Simple Configuration

Gone are the days of bulky handhelds with specialized drivers and complications: LXCAT software is powered by LXEdge, with the most up-to-date and scientific algorithm available. LXEdge is compatible with Windows computers and tablets allowing for maximum portability and simplicity of set up with the availability of regular software updates!
