## Summary/Discussion

One of the design flaws of the Spree device was that the signal would cut out, if the Spree band was too far away from the phone that the app was installed on. In order to enhance the signal strength of the spree device, an amplifier that was wireless could be attached to the spree device to boost the signal so it could accommodate a higher range, if the person wearing the device were to move farther away. After plotting the data for the heart rate and temperature of the gold standard and the spree band; the Pearson's Correlation for the heart rate shows a positive linear relationship while the graph for temperature shows no linear relationship between the Spree and Gold Standard. The Pearson's Correlation for the heart rate is not perfect, but it is almost positive one at 0.983355. A recommendation to enhance the accuracy of the temperature would be to measure the temperature internally instead of externally. This could be done by converting an ear thermometer to the size of a miniature headphone that could be attached to the spree band and just sit in the ear and automatically record the internal body temperature of a person at set intervals, which would not get in the way of the workout and would also allow the other ear to remain free to be able to hear others or listen to music.

## Target Population and Need

The target population includes all consumers of alcohol. The product is mostly geared towards people that are over the age of twenty-one and have the legal right to drink, but it is not limited to them alone. Dos Eyequis were invented in order to optimize the safety of the user and others that are around them to reduce the number of alcohol related accidents.

We created this product because of the dangers associated with decision making under the influence, mainly drinking and driving. In 2012, approximately 10,000 people were killed because of drunk driving. On average, every 51 minutes someone is killed because of drunk driving and every 90 seconds someone else is injured. The number of drunk driving related deaths can be lowered because this issue can be avoided. In an effort to reduce injuries and fatalities caused by drinking and driving, we invented a device that will help keep drinkers, and those around them, safe by measuring the BAC of the user. An app can be downloaded onto the phone and programmed with the user's contact information of relatives and/or friends. The app will measure the blood alcohol content of the person through the contact lenses and will send out an alert when the drinker is heavily intoxicated. The app will then alert the family or friends of the location of the user who is wearing Dos Eyequis and will be able to pick them up and drive them home safely. Not everyone plans to drink past their limit when they go out for a night of fun, but Dos Eyequis will ensure that the user will always have a designated driver that is not under the influence.

## Device Design

The device will be a pair of contact lenses that have nanotechnology installed in order to perform the functions advertised. The nanotechnology will have the ability to test the blood alcohol content (BAC) of the wearer by taking samples of tears, and then relaying the information back to a smartphone application. The app will then analyze the BAC and determine whether or not the user is over the limit of intoxication; if so, the program will alert the contacts of the wearer that were initially programmed into the application, allowing one of them to track him/her down and pick them up.
