Retrieve

2. Outline the elements this invention retrieves from past technologies.
This invention retrieves a few things from past technologies, although it is very innovative and new. One that comes to mind is the little toy that people enjoyed when they were children which you looked into and it showed you different images when you pressed a button. Also, the kaleidoscope is another thing that you look into and see things that are not there. Also, the function that alerts health care workers of the wearer’s physical health is similar to the devices that elderly people wear in case they fall and cannot get up or are in trouble in some other way. This is simply an extension of this because if the user is knocked unconscious, they will still receive help. It also retrieves the now almost obsolete contact lens and glasses because many people are getting laser eye surgery.
