  • Strip-based ventilation solution for electronic equipment
    Patent number: 11140800
    Abstract: 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.
