-**Bracelet power consumption** : 4.5+115.2+13.32+6+6+4= **149.02‬‬ [mW]**

 This peak power consumption will, however, never be reached. The body temperature sensor will only be active twice a day, taking a measurement in the morning and one in the evening. The only component which needs to work in normal mode constantly is the pulse sensor, while the other components can be used in a deep-sleep/low-power regime or only when necessary.

 Below is a typical current consumption for the bracelet while sending data and having **all components active**: 1.5+24.6+3.7+0,0027+1.2+2=**33.0027‬‬ [mA]**

+**Deep-sleep current consumption:** 0.001+0.001+0.0198+1.2= **1.2218 [mA]**
 Taking into account the 600 mAh battery, this would provide us with approximately 18 to 20 days of deep-sleep functionality. With proper battery management and efficient coding, we should be able to provide our customers with the 2 weeks functionality we initially planned for, while perpetually monitoring pulse and oxygen level, as well as having the accelerometer active for detecting falls.

 In order for these trees to survive, care and precision are needed and their harvesting must be done carefully. This process is "carried out entirely by the skilled hands of local workers rather than machines". Cork harvesting remains very important for both the environment and the local economy, as they "are some of the highest-paid agricultural field workers in the world" ((corature)). An authorization from the Portuguese Ministry of Agriculture is required because it is illegal to cut it without a permit.
-Another major positive fact about this tree and one of the reasons why it makes such a sustainable material is that every year cork production in southern Portugal absorbs 14 million tonnes of CO<sub>2</sub>. "After a tree is stripped of its bark, it can take in roughly five times more CO<sub>2</sub> than an un-harvested tree" ((corature)). This means that the continuation of the cork harvest actually protects these forests. They also help prevent erosion and preserve the water supply, and without them, these areas would be deserts.

-After removing all products, the buyer can place the medicine organizer at the bottom of the package as in the example in **Figure {{ref>pre}}**. In this way, the elderly will have a special space for daily pills that prevent them from falling every time the box is opened. Also, another advantage is that the treatment will be taken properly and the pills are kept in a proper environment. The inside of the box under the medicine organizer can be used to store pill blister packs, jewelry, or other objects.
