Your task is to draft three patent claims to cover your invention. Please make sure to follow the standard format of a claim (X comprising/consisting of Y element(s)).

1. For the first question, you will need to demonstrate what it means for a patent claim to be "broad." You will also need to show an understanding of what a PHOSITA is.

2. The second question will require you to understand the novelty requirement, the non-obviousness requirement, and the "fully and appropriately described" requirements in the patent law context.

3. Question three will require you to demonstrate that you understand what it means for a patent claim to be "narrow." Emphasis should be placed on the "fully and appropriately described" requirement.
