Abstract: An enclosure protects electronic equipment from physical contact and electromagnetic interference. The enclosure includes a base portion which is attachable to a circuit board and which surrounds all sides of the electronic equipment. A cover is attachable to the base in order to cover the top of the electronic equipment. The cover is attachable to the base by snap-in tangs formed on the base which cooperate with projections formed on the cover. The base is attachable to the circuit board by snap-in fasteners formed on the base. The base and the cover are made of a material which reflects and/or absorbs EMI. The EMI shielding enclosure protects the electronic equipment and allows access to the electronic equipment for replacement or repair without having to take the time to manipulate separate mechanical fasteners.

Abstract: A modular apparatus is described which houses electronic equipment. The apparatus includes a plurality of electronic modules surrounded by an air vent system. In one embodiment, the air vent system cools the electronic components indirectly, through a connection module. In another embodiment the electronic components are cooled directly. One of the main advantages of the present invention is its modular configuration which allows additional components to be added with relative ease as the requirements of the system are expanded over time.
