Homework 1
Patent 4,697,285: Ballistic Vest
Date Issued: October 6, 1987
This patent describes a ballistic vest as a worn garment designed to protect the wearer from bullets and/or explosive shrapnel. This patent is for a vest that is comprised of a front panel that will protect the front end of the user as well as a rear panel. These panels are held by front and rear carriers, respectively, and are connected to the carriers by elastic straps which are rigidly fixed to the edges of the panels. The panels are composed of multiple layers of flexible impact-resistant material, such as Kevlar, that are contained within a flexible jacket. The layers are free-floating across the area of the panel, making the vest light and comfortable to wear. The rigid fixing of only the edges of the layers to the fasteners ensures that they will remain intact after multiple bullet impacts from different angles as tested.

Homework 2
The patent for a ballistic vest described above cites two earlier patents, 4,079,464, by Sam Roggin, and 4,483,020 by Anthony G. Dunn. The earlier patent by Roggin dates to 1978 and is for a "Protective Garment" that incorporates a folded segment of Kevlar sealed together by a thermosetting resin into the front and back plates, which are connected by shoulder straps. The latter by Dunn from 1984 reflects a development in the protection offered by the vest wherein multiple layers of hard and soft bullet resistant material act together to stop a bullet. This solved a problem with earlier vests in which wearers suffered blunt trauma type injuries from the kinetic energy impacted by a slug hitting the vest. These patents follow shortly after patent 3,829,899, which was awarded in 1974 to Second Chance Body Armor Company as the first bullet resistant article of soft clothing.
There are many similarities between the ballistic vest patent of 1987 and the earlier patents but also distinct new innovations.
