SOBERRIDE

The MQ-3 sensor works by measuring the concentration of alcohol in the air through the change in electrical conductivity of its sensing material, which is typically a tin dioxide (SnO2) film. The MQ-3 sensor mainly only detects ethanol, which helps the sensor differentiate between substances like toothpaste and liquor. It sends an analog signal to the Arduino with the concentration. The concentration will fall in a certain range, and based on that range as well as inputs from the quantum AI model and retinal eye scanner, the device will classify the driver as drunk or sober.

Under proper conditions, the sensor can detect alcohol concentrations within a range of 0.05 to 0.5 mg/L with a resolution of 0.01 mg/L. However, although this is already fairly accurate, we have been working to increase the accuracy with the addition of our AI model and retinal eye scanner. Using the sensor, model, and scanner brings the error rate close to zero.

Under typical usage conditions, some manufacturers estimate that the sensing material can last for 7 years. After that time period, they will have to get the sensor checked on. If eroded, the sensing materials will have to be replaced. However, it's relatively cheap to replace these sensors and we will provide this service to our consumers.

After working with one of our Ford advisors, we learned about a Controlled Area Network (CAN). It connects to the internal vehicle system if placed near the ignition of the vehicle. OEMs will utilize a CAN to connect our 3rd party device to the vehicle's internal system.

Our device will send an alert if it is moved outside a designated proximity from the car. To ensure security, the system incorporates a retinal scanner that captures the driver’s iris signature to verify their identity during the test. If someone attempts to switch with the driver who has taken the test, they must undergo a scan. If the new individual is not cleared as sober, the car’s gears will remain locked in park, preventing the vehicle from being driven.

The breathalyzer will scan for the driver's alcohol level right before the driver starts to operate the vehicle. The breathalyzer will be near the B pillar of the vehicle. If the concentration of alcohol is within legal limits, it will allow the driver to operate the vehicle. The retinal eye scanner will be located in front of the dashboard around half way up the steering wheel. It will use a camera which constantly scans the driver's eye to make sure the driver doesn't switch seats with anyone to bypass the device. The camera doesn't use laser or anything harmful to the human eye.

We will make sure we explicitly tell the driver what information is being sent to the insurance company and what isn’t. The driver will have full control of what they want to send as well and they are allowed to not send anything at all to the insurance companies. If the driver doesn't want to show their device readings, that is fine. They will be provided with all related terms and conditions and there will be no hidden details.

If the driver is not yet an adult, and thus below the age of 18, their parents will have to sign a waiver as their legal guardian authorizing the device the ability to check the teenager for alcohol when driving. If the driver is 18 or older, they can authorize this for themselves.

We will do extensive testing on the sensor and measure the sensor's accuracy. We will make sure we include this in print on our device instructions. We will also make the user sign a waiver, which declares that this device has a goal of helping the driver, but after all, it’s the drivers choice to drive after drinking. The device is meant to serve as an aid, and the driver will be 100% responsible for their own actions. This waives their rights of suing SoberRide for any false negatives.

We will have an override from the app if needed. This override will ask a few simple questions to make sure the driver is sober via the app, and unlock the vehicle if they are sober. We will also take steps to maintain security using our retinal eye scanner to make sure the driver isn't asking a third party to answer the questions on the app for them.
