Subject – Result analysis: Nexense “SleepAP” VS PSG (Embla A-10).
Attached please find summary reports of a sleep study conducted 20-May-07.
Subject description:
Female,
Age – 45,
Height -162cm,
Wight – 96kg,
BMI = 36.64.
The study was conducted in the patient’s home using A – 10 Embla PSG & “SleepAP” by Nexense
Simultaneously, the subject was reefed to the study due to – excessive daytime somnolence & snoring.
The PSG results show an RDI = 21 respiratory events per hour.
EEG shows no indication of abnormal motor activity.
Sleep Stages – ~ normal- with REM time slightly shorter then normal for her age.
The SleepAP system detected – a total of 24.3 respiratory events per hour for the same duration.
I find The difference in results low & is probably due to definitions of event analysis that is not standard – in terms of sensitivity I find this system interesting & shows promise – need to conduct several studies more in order to validate the findings.
Conclusion: The SleepAP system shows promise & when validated could be used as a great screening tool for OSA.
Respectfully,

Introducing NexaverTM SleePure
The Revolutionary Anti-Snoring Solution
“Because Quality of Life Begins with a Good Night’s Sleep “
Nexense Ltd., a world leader in sensor technology, is proud to introduce its Revolutionary Anti-Snoring Solution, NexaverTM SleePure.
It has been well documented in recent years that sleep-related breathing disorders, especially snoring, have been linked to several types of heart disease, including an increased risk of heart attacks, high blood-pressure, stroke and other cardiovascular events.
“Loud and frequent snoring can be more than a nuisance to your partner. This nighttime annoyance may indicate a serious health condition and it can disrupt your household and strain your relationship. “

Snoring is a wide spread sleep disturbance effecting the whole spectrum of the adult population.
• 30% of those over age 30 snore, rising to 40% in middle-age.
(Source: British Medical Journal, 1997)
• Two-thirds of partnered adults say their partner snores, while 6 out of 10 of all adults say they snore.
(Source: National Sleep Foundation, 2005)
• Male: Female ratio= 2:1 with the gap closing after menopause.
(Source: Vancouver sleep and breathing center)
What is also widely known is the relationship between habitual snoring and various types of Sleep Apnea.
• Sleep Apnea may be present in 20-40% of the adult population that experience snoring. (Source: National Sleep Foundation)
The devastating consequences of a person suffering from Sleep Apnea have been well documented in medical studies.
• An individual with untreated apnea (OSA) is up to 4 times more likely to have a stroke and 3 times more likely to have a heart disease. (Source: National Sleep Foundation)
• People suffering from sleep apnea are 6 times more likely to be involved in a car crash than those without sleep disorders. (Source: New England Journal of Medicine, 1999)
Nexense Ltd., utilizing its quantum leap innovative sensor technology, has developed a proven solution to the snoring problem, the Nexaver™ SleePure System.
The Nexaver™ SleePure System monitors sleep behavior and outputs a gentle biofeedback upon snore detection. The System allows users to learn how to enjoy free air flow to reduce or cease snoring. The Nexaver™ SleePure improves sleep quality and potentially reduces this risk of long-term heart-related conditions.
The Nexaver™ SleePure System has been successfully tested and has shown excellent results in significantly reducing the amount of snores as well as reducing the intensity of the less frequent sleep disturbances.
To date, the effectiveness of currently available anti- snoring products have either been virtually ineffective, extremely costly or terribly uncomfortable.
The enormous, untapped, sleep disturbance market requires a more effective, more economical and more user friendly solution. The market deserves The Nexaver™ SleePure System.

Nexense sensor detection validation
SleepLab Snore Detection ValidationThe validation used polysomnography as the golden standard for detection of snoring events with a calibrated microphone. The subject underwent a short polysomnography examination. During the examination, the Nexaver TM SleePure sensor was placed below the subject's mattress.
The data from both sources was recorded and compared simultaneously.

SleePure - A new non-invasive sensor technology reduces snoring

The Nexense Measurement Method
By applying the known principles of physics in a unique way, Nexense has managed to improve a measurement method, which has led to a means of improving a broad variety of sensors, used among other things to detect, recognize and discontinue snoring.
Nexense’s measurement method enables sensors to be designed so that they are up to
100,000 times more sensitive than current sensors.
The Nexense measurement method enables many different physical parameters to be more accurately measured. Specifically, they have been shown to provide a significant improvement over traditional sensors for the following physical parameters: distance, weight, strain, pressure, acceleration, temperature, vibration, volume, viscosity, density, mass, displacement, flow, torque, shape, tilt, and more.
Snoring has been found to increase in frequency with age. Snorers are commonly overweight and frustrated by the social consequences of their noisy night-time resonance. Sleep disordered breathing including habitual snoring is associated with hypertension, heart disease, cerebrovascular disease, and daytime sleepiness.
Using the non-invasive Nexense technology (The SleePure ) we have tried and managed to reduce dramatically the amount of snoring in a matter of days. (Figure 1)
Figures 2: shows data recorded during sleep, which includes heart rate, respirations, movements, and snores. The sensor is placed under the mattress and records the user’s movements, heart rate, respiration and snores. It allows the evaluating of the amplitude and rate of these indexes in detail. The highly accurate sensing method enables us to identify the different components, in a way that once the sensor documents the vibration of a snore, a vibrator starts to shake around the wrist of the person. The shake is gentle enough not to bring the person to full consciousness, yet he stops snoring. During the last years we performed sleep studies on 30 patients known as "snorers" during 500 nights all together.
Figure 3 shows the number of snore's episodes during 5 days with and without the SleePure system.
We succeeded to achieved a dramatic reduction in the number and the intensity of snores.We conclude that by using the Nexense SleePure system we can reduce the number and duration of the snoring episodes and improve the quality of sleep in the snoring population and we will soon perform a controlled study to prove it.
Nexense Ltd. Sleep Apnea
INTRODUCING THE NEXAVERSLEEP APNEA CARE SYSTEM
A New Effective Non-Intrusive Alternative Treatment for Sleep Apnea .
General:
Currently, Sleep Apnea is treated with a CPAP. This device is known to be a very uncomfortable and cumbersome piece of machinery that causes a significant number of apnea patients to refrain from complying with their doctor’s orders in wearing the CPAP mask. A long list of common problems supplied by CPAP users discourages many people of using it despite the fact that these people are aware of their need to use it.
The Break Through:
Nexense has developed an effective and unique system for treating sleep apnea that uses biofeedback methodology. This system does not change the user’s habits, the user does not have to wear any mask on his face and the user’s quality of sleep may also be upgraded as the system is capable of treating the common sleep disturbance closely related to sleep apnea known as snoring.
Additional Advantages:
The Nexense product can also be used as a home sleep lab system where the user can get his/her sleep analyzed in the comfort in his/her own home without being connected to any electrodes. This allows for a thorough examination over time which can result is a more accurate diagnosis of the user’s true sleep problem . Nexense has also developed the software needed for automatic screening and sleep analysis.
Business Opportunity:
Nexense is looking for strategic business partners to promote its technology in this field and to collaborate with the right player in order to move forward in attaining FDA approval and for market distribution purposes.
