The Phalanx Monitor uses the saliva of an individual and scans it to see if the person has been exposed to a sexually transmitted disease (STD) covered by the device. This is to eliminate the more invasive or strenuous methods of STD detection of extracting body fluids, such as blood, urine, vaginal or seminal fluids. This device targets the 18-45 year old demographic in the United States. Such a selection is based on the belief that men and women of ages within this group are at the highest risk of STD exposure.
Due to the astronomical amount of total individuals who have potentially been exposed to some sort of sexually transmitted disease, the Phalanx Monitor targets the five most commonly known STD’s in American society: HIV, Syphilis, Gonorrhea, Chlamydia and Herpes. It is rather difficult to pinpoint the exact number of people the device will affect. However, the following values may possibly give more clarity on how many people the device will target generally:
Syphillis: Approximately 110,000 Americans affected
Herpes: Approximately 24 million Americans affected
HIV: Approximately 900,000 Americans affected
Chlymydia: Approximately 1.4 million Americans affected
Gonorrhea: Appproximately 800,000 Americans affected
Grand total (rough estimate): 27.21 million people in the United States
[[Image:PhalanxCustomerForm.jpg]]
Needs of the population:
Affordability: It is well understood that since the worldwide financial disaster of 2008, money has been a major issue for the majority of the American population. Everyone has been affected in some way since then. With the prevalence of sexually transmitted diseases in the nation, high quality STD testing comes at a price. Our device aims to offer the best quality product at a price which is made to be the most affordable to the population. If the people affected are unable to purchase an STD test, there are more susceptible to inaction regarding their condition, allowing the disease to more effectively ravage their bodies.
Accessibility: Being able to purchase the product directly from the company’s website and phone number shows that the device is not difficult to acquire.  People, especially the younger age groups in the demographic targeted, have trouble being able to figure out where to go to get the equipment or tools they need for their condition. The company aims to simplify the accessibility process in order to assure that our device can fall into the right hands when it is needed.
Accuracy: No amount of testing can erase the critical nature of data accuracy. If an individual suspects they may have contracted an STD, they want to be sure that if they complete an STD test, they want the disease identified as close to 100% of the time as possible. They do not want to risk the confusion that they may have contracted more than one disease from a simple saliva test, or if they’re symptom lead to something potentially worse than what is really is. Our device is estimated to have a nearly 99% accuracy level for identifying the appropriate STDS from the person’s saliva. 
Privacy: The history of sexuality in America has consistently been of a reclusive and conservative nature. Despite the amount of advertisement readily available in numerous media outlets, the American population is reluctant to have an open and honest discussion regarding sexual intercourse, outercourse or any sort of similar activity. Having to purchase and use an STD test can be humiliating and embarrassing for people who do not want to disclose such problems. At our company, the purchase and use of our device demands the absolute amount of privacy an individual has rights to. The device can be purchased at our company website or phone number with total privacy. Products shipped to the homes of individuals do not advertise the product itself. Only the person who bought the device knows what is in the package that arrives at their door. The device can also be shipped to a specified address if the person does not want their family, relatives or friends to find out that they have purchase the device. Hospitals, health clinics, school and university health services are excellent examples of product acquirement with total privacy.

Heart Rate T-Test Value and Additional Data



Analysis

The team studied the effectiveness of the Spree headband compared to the thermometer and the Pulse Ox device which both served as gold standards for measuring the heart beats per minute and the temperature of a subject respectively. Data analysis showed that the Pearson's Correlation Coefficient of -0.053072216 for temperature represents a negative correlation between the Spree headband and the thermometer. The temperature's T-Test value of 8.5316E-20 is less than the alpha value of 0.05, which is used as a standard to measure data significance. This indicates that there was a significant difference in data between the headband and the thermometer. Based on these two factors, the team believes that the headband was insufficient in measuring the body temperature of an individual accurately.

However, the team's data for measuring the rate of heart beats per minute gives a different conclusion. The Pearson's Correlation Coefficient of 0.51788901 indicates that there is a positive correlation between the Spree headband and the Pulse Ox that was used as a gold standard. This discovery is reinforced by the T-Test value of 0.116138892 that was also determined. Since this value surpasses the standard alpha value of 0.05, the conclusion that there was no significance in data between the two temperature groups can be made. This may suggest that data accuracy for measuring the heart beats per minute in an individual may be more apparent, giving the Spree headband more legitimacy in that area of expertise.



Summary/Discussion

Before the team gives their opinion on the Spree headband device, a disclaimer regarding the experiment must be made. The team's study of the device was postponed by forty-five minutes of time. There was an insufficient amount of Spree devices provided for the laboratory and the supervisors of the lab were forced to find more. This large gap in available time for the experiment proved a hindrance on data collection. The team personally was only able to accomplish half of the experiment with the remaining time left, which may have played some sort of role in the conclusions made regarding the Spree device.



With the aforementioned information above, the Spree headband device was an attempt of being a multipurpose fitness tool capable of providing any major needs an individual would have in those activities. It was a failure for several reasons. First, the device required consistent motion on the individual's part in order for data collection to occur. Placed on the forehead, the individual would be less likely to move their head compared to other body parts, such as the wrist or the leg. The team believes that by relocating the device to a more active area on the body, the Spree device would have had better data accuracy and overall reliability, if motion does have to be a factor here.

Second, the stress the Spree headband placed on the battery life of a mobile smartphone seemed to be too demanding. One of the research team's members used their Apple iPhone for data collection. The iPhone started with a charge of 35%. By the conclusion of the experiment, the phone was down to a charge of 7% after one hour of use. The team was forced to end the experiment at this moment. They understood that mobile Apple products have a failsafe battery shutdown at 5%, to prevent the death of the mobile's battery. The team recommends that more measures are made to improve the battery demand of the Spree device in order to justify its use to begin with.

Lastly, the data collection and how it was represented by the Spree headband was not as simple as the company had advertised. The temperature of an individual was measured using a color and level code. On the device, blue was level 1, yellow was level 2, a partially filled red bar was level 3, and a fully red bar was level 4. No actual numerical measure was given for temperature, which required the team to decipher what each level meant. This system of measuring temperature is ineffective in providing what the customer would want when recording body temperature. The team recommends the removal of the color and level code and replacing it by using both the Fahrenheit and Celsius numerical method. This is to provide a more simplistic interaction with the Spree device and the individual who uses it.

Target Population and Need

The Phalanx Monitor uses the saliva of an individual and scans it to see if the person has been exposed to a sexually transmitted disease (STD) covered by the device. This is to eliminate the more invasive or strenuous methods of STD detection of extracting body fluids, such as blood, urine, vaginal or seminal fluids.

It is rather difficult to pinpoint the exact number of people the device will affect. However, the following values may possibly give more clarity on how many people the device will target generally:
