Abstract: A conductive signal transmission structure for a printed circuit includes a copper material and a graphene layer disposed within the copper material at a depth below a surface of the structure. The depth of the graphene layer is further within a skin depth region of the structure when a transmission signal applied to the conductive signal transmission structure has a signal speed of at least 112 Gbps and/or a Nyquist frequency that is at least about 14 gigahertz (GHz).

Abstract: Presented herein is an air vent including a plate, and a non-uniform array of openings extending through a thickness of the plate. The non-uniform array of openings arranged to admit a flow of cooling air through the plate. The plate and the non-uniform array of openings are arranged to attenuate electromagnetic interference (EMI) emitted through the plate.

Abstract: A system includes a millimeter (MM) wave radar detector, where the MM wave radar detector generates signal data associated with a person of interest (POI) within a field of view of the MM wave radar detector. The system further includes an Access Point (AP) coupled with the MM wave radar detector. The AP includes a computing device to receive and analyze the signal data provided by the MM wave radar detector to determine a movement or action of the POI within the field of view, and facilitate generation of a feedback response in response to the determined movement or action of the POI.

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.
