FYI,Lafayette Polygraph is releasing a new movement sensor developed here at NCCA. The "Masseter Movement Headphones" are (as the name implies) a set of headphones in which movement sensors have been installed into the ear cups to pick up facial based CMs (tongue biting, teeth clenching, etc). the prototype we developed at NCCA worked great at picking up these movements and I am optimistic the Lafayette unit will work as well (I have not yet seen their unit in action). Additionally, MMH headphones also serve to block out outside noise and can used as part of computerized presentation of test questions (to include foreign language translation programs) As not to "push" any particular vender, I am told the folks over at Limestone are right behind Lafayette on this new technology and I understand their masseter unit will also be out shortly. A FINAL NOTE: As a government employee it is critical I remind anyone who reads this that any opinions I have expressed here are not necessarily those of the U.S. Government, nor does the government endorse this or any other particular product.

Please be assured that Limestone Technologies is focused on covering all the bases with respect to physical countermeasures. We have recently released a true USB instrument that is dedicated solely to the task of detecting, identifying, and recording all examinee movements during an examination. The Limestone_MMS is an instrument with five dedicated activity sensors that are used to provide exact activity information from multiple sites. Example sites include the following: right arm, left arm, feet, seat, face, jaw, tongue, etc. The MMS will work as a value added USB accessory that is devoted to recording and displaying examinee movement activity. The Limestone examiner has the power to now display and record up to seven channels of movement activity. These channels can be recorded and displayed independently as individual channels or they can be multiplexed into one channel to minimize chart clutter. When the channels are multiplexed, a chart annotation will clearly identify precisely where the movement originated. The examiner will easily be able to discriminate exactly where the activity originated and in synchronization with their recorded polygraph chart data. With the Limestone_MMS there will be no value in trying to manipulate the test results with any physical countermeasures. Imagine the following scenario. “I can clearly see that you’re moving your left hand and biting your cheek...” you’re busted! Cheers,

All,My post regarding Lafayette's movement sensor (and reference to Limestone's efforts) was in no way meant to imply that Lafayette's or anyone elses technology was in any way ahead of Limestone's. If that is how it appeared or was percieved then I would hope the folks at Limestone would accept my apology.. IP: Logged |

There's absolutely no need for an apology. I wasn’t offended in any way and I just wanted to take the opportunity to let examiners know that Limestone Technologies is working diligently to eliminate any chance of test manipulation.We’re all in this together and our mutual co-operation is the best recipe for success. Sincerely, --

Well said by both of you. As you might remember, the piezoelectric movement sensor pad was developed by a contractor employee at DODPI and the technology was provided to all the vendors, most of which developed variations and enhancements to the basic pad design.We desperately need innovation in this area and it is welcomed. I had an opportunity to view the MMS system developed by Limestone at the APA last week and it's really sharp! We're getting really good at picking up signal noise, artifacts and countermeasures.....I just wish I knew what the rest of those squiggly lines mean.
I'm currently developing the IMPACT+3 scoring system. IMPACT stands for Igonre Most Pneumograph And Cardio Tracings,give three points to the EDA. So far, it works great and inter-rater agreement between me and my QC folks is really high. But I think they've been using it for years!

Skip,You are one witty forensic psychophysiological detection of deceptionist! And funny to boot, IMPACT-3... very witty Mr. Webb. ------------------
