Healthcare at Home (Part II)
A major trend in medicine is to move treatments and monitoring out of the hospital or even the doctor's office and either attach them to the patient or enable it to be done in the home. What can device designers do to aid this effort and what technologies would help to enable it.
(EDN, February 25, 2008)
Human Fall Detection Using New MEMS Accelerometer Technology
For humans, an unobserved fall can have very serious consequences. Statistics show that the majority of serious consequences are not the direct result of falling, but rather are due to a delay in assistance and treatment. Post-fall consequences can be greatly reduced if relief personnel can be alerted in time.
