Systems and methods for preventing leakage of electromagnetic waves from electronic devices, or for preventing unwanted RF fields from entering an electronic device. According to an aspect, a system includes a body and a cover positioned to define an enclosed interior space for placement of an electronic device. The system also includes a gasket attached to or integrated one of the body and cover to seal the interior space from outside the electronic device enclosure. Further, the system includes an electromagnetic wave absorptive material attached to a portion of the gasket for absorbing electromagnetic waves generated within or outside of the electronic device enclosure.

A fan assembly includes a fan having an outlet side, a fan duct positioned at the fan outlet side, and a hollow cylindrical chamber positioned within the fan duct, wherein the chamber has two closed ends, a cylindrical side wall, and an inlet port. The dimensions of the chamber are determined to suppress one or more noise frequencies emitted by the fan. In one example, one or more dimensions of a chamber disposed in an outlet duct of an axial fan is automatically adjusted to suppress a noise frequency that is a function of a rotational speed of the axial fan.

Embodiments of the invention relate to a primary contact or primary body comprising of a primary material with a propensity to corrode. A location on a surface of the primary body is an active location and functions to interface with a secondary body. The active location has a first surface and an oppositely disposed second surface. An anode material is applied to the second surface adjacent to the active location on the first surface. The primary body is exposed to a corrosive material. The anode material functions to divert a galvanic corrosive medium from the active location to the applied anode material.
