Assume that you are hired to develop an automatic patient monitoring system for a home-bound patient. The system is required to read out the patients heart rate and blood pressure and compare them against specified safe ranges. The system also has activity sensors to detect when the patient is exercising and adjust the safe ranges. In case an abnormality is detected, the system must alert a remote hospital. Identify the actors and their goals. Briefly, in one sentence, describe each use case but do not elaborate them. Draw the use case diagram
