  • Electromagnetic interference shield for data storage systems
    Patent number: 7492608
    Abstract: A system including an EMI shield. In an embodiment, the system includes a chassis with at least one bay for receiving a replaceable unit and a lip. The replaceable unit includes a housing and a faceplate. Further, a gasket is operationally coupled to the replaceable unit housing and the replaceable unit faceplate for reducing electromagnetic radiation emissions from the replaceable unit and chassis interface. The gasket may include four sides which are configured to provide a varying force-compression curve along the length of the gasket. Upon installation of the replaceable unit, the lip defined within the chassis compresses the gasket to provide a constant force per unit length and form an electromagnetic interference shield with uninterrupted electrical conductivity.
