VENTILATION SOLUTION FOR ELECTRONIC EQUIPMENT
An apparatus suitable for providing ventilation and electromagnetic interference (EMI) containment for a computing device includes a first strip and a second strip. The first strip is sized to span ventilation openings of a computing device covering. The second strip intersects the first strip while also spanning the ventilation openings. Thus, the first strip and the second strip cooperate to define airflow openings within the ventilation openings, the airflow openings being sized to inhibit EMI from exiting the computing device via the ventilation openings.

Lightning strike and electromagnetic protection system
A composite article for incorporation at the surface of an assembly, the composite article being capable of withstanding a lightning strike by dissipating the energy of the lightning strike and by shielding the assembly from electromagnetic energy associated with the lightning strike. The composite article has a base structure made of a material exhibiting electrical conductivity that is inadequate to dissipate lightning strike energy and also inadequate to shield the assembly from the associated electromagnetic energy. Against the outer face of the base structure an electrically-conductive lightning shield is secured. The lightning shield has a substantially uniformly-distributed embedment of electrically-conductive nanostrands in a matrix that otherwise exhibits electrical conductivity that is inadequate to dissipate lightning strike energy and inadequate to shield the assembly from associated electromagnetic energy. Alternatively, an electrically-conductive ground plane may be secured against the outer face of the base structure.
