Aithre Inc
AVI-G 1-Place Smart O2 Valve Designed for Glider Installation
This is a standalone AVI smart pulse system that is usable with any existing aviation oxygen bottle with the provided Mountain High Regulator.
The included MH Regulator is custom-made by Mountain High Oxygen Systems specifically to enable use of the Aithre AVI with an existing oxygen bottle. The regulator enables use of any existing brand of oxygen bottle (such as an aluminum, Kevlar, or carbon fiber bottle sold by Mountain High, Precise Flight, or Aerox/SkyOx) by converting the legacy bottle to one that supports the AVI smart pulse system. Note that the oxygen bottle itself is not included in this system.
The Altus AVI is the first smart oxygen system that is integrated with your iOS device and the Aithre suite of health technology products to deliver smart pulsed oxygen. You get a lighter bottle with a pulsed delivery system that factors pressure altitude, respiration rate, and custom user parameters to extend oxygen duration by more than 4X. This lightweight system offers incredible endurance, which time can be extended more using the Aithre Illyrian oximeter.
Other important features are a wireless Altus pressure gauge, respiration rate and flow rate monitoring, and auto oxygen on/off settings based on measurements of oximetry, heart rate, carbon monoxide, and pressure altitude. Additionally, the emergency mode with higher flow rates equivalent to 12.5 LPM starts automatically when using the app or Healthview when your Aithre Illyrian measured oximeter reading drops below 85%, Aithre Shield carbon monoxide levels exceed 50 PPM, or pressure altitude of 18k MSL is reached.
ONE PLACE
The AVI includes one quick cannula connect for the pilot that is powered by a MEMS flow-breathing detection circuit. A 100% silicone soft cannula ensures your total comfort - even maintaining supreme flexibility at low temperatures.
SMART PULSE
Our smart pulse system is the first ever to base pulsed oxygen on MEMS flow measurements. This technology provides enhanced inhalation detection plus provides real-time flow rate determinations and accurate respiration rate feedback. What makes the system smart is the integration with the Aithre Connect iOS/WatchOS app and Healthview to control oxygen and pulse duration based on respiration rate and pressure altitude. Simply plug in your cannula, push the button, and oxygen will begin pulsing. The AVI titrates automatically the oxygen delivery amount based on pressure altitude and provides for further user customization and emergency overrides. Further, with the Aithre Illyrian oximeter, the app allows the pilot to scale down the total oxygen delivery amount to squeeze every drop of useful oxygen out of the system without compromising safety.
HEALTHVIEW
The Healthview is the first dedicated avionics display for health information, including gauges for blood oxygen, heart rate, respiration rate, flow rate, cabin pressure, cabin temperature, carbon monoxide, oxygen tank pressure, and wing tip temperature/dewpoint spread - and the first dedicated avionics display that controls your oxygen dosage per station based on altitude, carbon monoxide, blood oxygen, and heart rate.
The Healthview features a 240 x 320 pixel TFT resistive touch LCD display with rich and vibrant graphical gauges, enclosed in an ultra-compact aluminum anodized laser etched case. The Healthview is powered by three parallel low energy processors and a wireless communication module for an exciting low heat, low power, high functionality display, using only 150mA of current at 14V.
Available as either in portrait or landscape orientation, the Healthview will fit in any panel design. The portrait or landscape orientation must be selected on purchase as a variant and is not changeable in the field.
The Healthview works as a standalone device for cabin pressure altitude, using an internal barometric pressure sensor. But, the real power lies in the Healthview's ability to dynamically expand to feature any available Aithre device, wirelessly and with OR without use of the popular Aithre Connect iOS app. The Healthview is compatible with all Aithre devices, including the Shield series of carbon monoxide detectors, the Illyrian oximeter, the Meso oxygen pressure, the AVI oxygen systems, and the Metis wingtip temperature/dewpoint sensor. Up to six Illyrian oximeters can be linked to the Healthview at any moment. Many of the connections are wireless, but the Healthview also features serial channels linking directly to the AVI.
Additionally, the Healthview controls the built-in AVI with dedicated serial communication, including pulse dosage based on pressure altitude and blood oxygen saturation levels. For advanced oxygen users, the Healthview provides an auto mode functionality that automatically turns your oxygen on and off on a station-by-station basis, using parameters of pressure altitude, SPO2, heart rate, and carbon monoxide.
You'll be proud to feature the elegant aluminum housing on your panel and it won't tax your battery. Power requirements are 12-18V and only 150 mA (0.15 A). Dimensions are 90mm x 61mm x 21.5mm and weight is just under 6 ounces.
MICRO BURST TECHNOLOGY
The AVI delivers each pulse of oxygen as a series of micro bursts with each inhalation. The micro bursts start immediately upon inhalation and extend over the first critical portion of the inhalation cycle. The number and spacing of the microbursts are adjusted in real-time and customized for each inhalation based on respiration length, pressure altitude, and other factors. The benefits of microbursts over a single pulse is that the oxygen is infused over the course of inhalation making the delivery smoother and more efficient.
RESPIRATION AND FLOW MONITORING
Respiration rate and flow information is updated about every 12 seconds in the Aithre Connect app and the Healthview, providing near-real-time snapshots of your breathing rate and the volume of oxygen being delivered. This additional information improves and replaces the physical inline flow meter that has traditionally been part of oxygen systems. And, the AVI can detect when a cannula has been disconnected or kinked because of the absence of respiration. Alerts are provided for start and stop of oxygen, high or low respiration rate, and when no respiration is detected on the pilot port, the AVI will sound an on-unit buzzer.
AUTO MODE SETTINGS
Auto mode allows for the AVI to be engaged and then activate on or off based on the thresholds for altitude, oximeter, heart rate, and carbon monoxide. Within the Healthview, the auto mode can be activated with a graphical switch for predetermined thresholds. Additionally, the iOS auto mode settings can be further refined to provide greater control of when oxygen should begin and end. There are four options in the app currently: pressure altitude, heart rate, SPO2, and carbon monoxide. Each option has a slider bar that allows you to set when the oxygen should start and then a touchable switch that enables or disables the setting. Any or all of the parameters can be defined so that whenever one of the variables is triggered, the oxygen will start automatically. For instance, pressure altitude can be set to 10k, SPO2 can be set to 92%, carbon monoxide can be set to 5 PPM, and heart rate can be defined as 100 bpm. If any of these parameters occur, then the oxygen will turn on. Conversely, if none of the parameters are met then the oxygen is off, but oxygen will always occur over 10k MSL while in auto mode. The heart rate is interesting because oxygen use is demonstrated to reduce your heart rate and we are observing the ability to impose resistance to heart rate surges during stressful parts of flight. The oxygen during carbon monoxide exposure will not prevent carbon monoxide poisoning, but may improve your odds of being able to remedy an exposure problem.
USER SELECTION OF PERCENTAGE OF STANDARD
The Aithre Connect app provides the ability for independent adjustment of the oxygen concentration per user. We have developed an algorithm that is based on the 1 LPM per 10K MSL that is used by the FAA. However, in some cases this amount is not sufficient for a user and more is desired to maintain a high SPO2 percentage. In other cases, this amount is too much and less oxygen concentration may be desired. Within the app, two slider bars are provided for the pilot and copilot that can be dragged to higher or lower percentages of standard. You can always increase the percentage of standard, but for safety you cannot decrease the percentage of standard below 100% without also wearing the Aithre Illyrian oximeter for continuous SPO2 readouts to your phone and paired headset.
ALTUS WIRELESS PRESSURE GAUGE
The system includes the Aithre Altus Meso wireless tank pressure gauge for installation with your current oxygen bottle. This provides 0-2500 PSI readings to your iOS device and the Healthivew in increments of 10PSI to permit monitoring of your oxygen bottle pressure.
ILLYRIAN II HAPTIC WEARABLE
This new revolutionary product delivers on Aithre's commitment to innovation and safety in flight with another first ever - a haptic safety wearable. Featuring an improved silicone pad and a built-in pressure altimeter, oximeter, heart rate and variability monitor, movement detector, and optional connectivity to the Healthview and Aithre Connect iOS app for cabin temperature and carbon monoxide sensing, the Illyrian II is packed with useful technology.
The haptic feedback is a first for aviation and one of the highlights of the Illyrian II. The use of repetitive audio speech for warnings can be obtrusive when flying an aircraft. Instead of disruptive speech, the Illyrian II relies upon a subtle haptic vibration that is amplified by the earcup of an active noise-cancelling aviation headset or felt on via the compression of the provided sport headband. This new modality provides information effectively, yet unobtrusively.
The haptic vibrator settings and controls can be setup via the app. A simple pattern alerts the wearer to safety issues without auditory disruption and without requiring an expensive headset upgrade.
- 1 Haptic Vibration => Cabin Temperature* or Miscellaneous**
- 2 Haptic Vibrations => Heart Rate
- 3 Haptic Vibrations => SPO2 or Carbon Monoxide*
- 4 Haptic Vibrations => Cabin Altitude
- 5 Haptic Vibrations => Head Movement
*Requires active use of Aithre Shield and Aithre Connect iOS app
**Requires active use of Aithre Connect iOS app
Power is via an exposed USB micro port. There is no internal battery, power levels, or on-off button to manage, greatly simplifying operation, reducing the weight and size of the Illyrian II, and minimizing the risk of inadvertent loss of power. Merely plug the in the Illyrian II to portable or dedicated USB power and the Illyrian II continuously operates for hours and hours at just around 10mA of current.
The silicone pad is a complete redesign of our original pad form. It is defined by a flat tapered wing shape with a honeycomb surface pattern. These improvements make the Illyrian II more comfortable to wear over long flights and less prone to shifting during movement. The Illyrian II pad remains designed for either headband or under the ear cup placement and the Aithre Connect iOS app is usable to find the perfect pad placement location for your body.
The Illyrian II is based on the same oximeter technology as the Illyrian I, which was given a prestigious Annual Editor's Choice award by Aviation Consumer magazine for 2018.
12V-14V POWER
The AVI smart valve is a 12V device that uses max current of 150mA. It can be wired to 12V ship power for experimental aircraft and includes an onboard fuse with over current and reverse current protection.
REGULATOR
The Mountain High regulator is custom made for Aithre systems and includes a standard CGA-540 female connection for your existing oxygen bottle. Output to the AVI is provided by a built-in 6mm push-to-connect hose fitting. The MH regulator outputs the pressure and flow volume of oxygen that is required for the AVI to operate.
Do not use any other unapproved regulator with the AVI to avoid malfunction or damage to the unit.
EASY INSTALLATION
The AVI is strapped to the bottle or mounted to the aircraft using the provided slide mount system. From there, the AVI accepts the 6mm plumbing line from the regulator and provides the output flow via the cannula quick release plug. The AVI will pass oxygen to the cannula when the power is provided and inhalation is detected. The Healthview is hooked to aircraft power and ground and then wired to the AVI using two dedicated com wires.
The AVI can be mounted up to 15 feet from the cannula ports. There is no requirement to keep the AVI on or near your person and the smart pulse operation is unaffected by this distance. The kit includes a plumbing kit and bulkhead fitting set to permit behind-the-panel plumbing to the pilot station.
BACKUP BOTTLE
A dedicated backup 47L carbon fiber composite bottle is provided for approximately 2.1 hours of 0.5 LPM continuous flow, independent of the AVI system. This small backup bottle is small enough to conveniently fit in a backpack or pocket and supports emergency oxygen access in the event that the primary bottle is depleted or there is loss of power to or malfunction of the AVI unit.
