Fan with EMI absorbent blades
An air-moving device with electromagnetic interference (EMI) reduction is provided. The air moving device, which may be embodied as a fan, includes a motor, one or more blades coupled to the motor, and each of the one or more blades comprising EMI absorbent material.
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.
Cover for socket of fan wall
A cover for covering an opening of a socket formed by a housing comprises a body; one or more bosses extending from the body, a first locking mechanism, a second locking mechanism, and a release tab. The bosses movably couple the body to the housing such that the body is movable between first and second positions. The first locking mechanism releasably attaches to the housing to secure the body in the first position. The second locking mechanism releasably attaches to the housing to secure the body in the second position. The release tab aids in detaching the first locking mechanism from the first wall and the second locking mechanism from the second wall. When the body is in the first position, the body allows access to the socket through the opening. When the body is in the second position, the body prevents access to the socket through the opening.
FRAMELESS EMC AIR FILTER
A frameless EMC air filter for a conductive enclosure includes a body comprising a conductive layer disposed between two filtering layers, the air filtering layers forming a periphery of the body. The frameless EMC air filter further includes one or more bare edge portions that extend outwardly past the periphery of the body. Each bare edge portion is formed by an extension of the conductive layer capable of providing direct electrical contact with the conductive enclosure.
Housing assembly and cover applied to electronic device
The present disclosure provides a housing assembly, and the housing assembly is applied to an electronic device. The housing assembly includes a first part and a second part. The first part includes at least one opening. The second part includes at least one mesh area. The mesh area deformably connects to the first part, and covers the opening.
Fans in series with cable plug interfaces
Method for and apparatus were fans and cable placed at the ends at the same end of a computer rack drawer. The cable ends are located between the fans and the computing elements. The bulk length of each cable passes through the region where the fans are located. Air, and optionally EMI, sealing are provided by an elastic material near the fans. In this way cables could exit the same tailstock of the drawer where fans are located. The cable ends can receive good cooling, and the distance between the cable ends and computing elements of the drawer is not lengthened by the fan position.
Electronic device with a thermal and EMI shield
An electronic device is disclosed. The electronic device includes a shield that provides thermal and electromagnetic interference (EMI) shielding benefits. The shield is secured with fan assemblies by airtight seals to prevent air leakage and promote a pressured volume when the fan assemblies are running. Further, the shield can direct airflow from the fan assemblies to one or more thermally conductive components, where the airflow can convectively cool the thermally conductive components and exit the electronic device. The shield is made from a metal, and when the shield covers a circuit board, the shield protects an EMI barrier for integrated circuits located on the circuit board. Moreover, the shield can provide a single-piece, monolithic body that provides advantages over multiple shields, such as eliminating gaps in the shield for air leakage and EMI intrusion, increasing air circulation efficiency, and decreasing costs.
Flexible electromagnetic shielding that attenuates electromagnetic interference
Described herein is electromagnetic shielding that is configured to attenuate electromagnetic interference (EMI) by at least a threshold amount when the EMI has a frequency within a predefined frequency range. The electromagnetic shielding includes a layer of metal, such as aluminum foil, and a layer of thermoplastic polymer fabric (such as woven polyethylene fabric), where the electromagnetic shielding has several apertures that extend therethrough. The electromagnetic shielding is at least partially draped over electronic equipment that is to be shielded from EMI.
System and method for optical state determination
A method for managing electromagnetic interference (EMI) includes: obtaining electromagnetic radiation from a device, disposed in an internal volume of a data processing device, while the internal volume is EMI isolated and after the device performs a function; making a determination that the device disposed in the internal volume has an optical state associated with the electromagnetic radiation; and performing a first action set based on the determination, in which the electromagnetic radiation is obtained through a boundary of the internal volume.
SYSTEMS AND METHODS FOR AN ELECTRONIC DEVICE
Methods and systems for an electronic package for a vehicle are provided. In one example, the electronic package includes a chassis having a plurality of bent tabs forming a plurality of respective vent openings in the chassis, and a circuit board coupled to the chassis, wherein the bent tabs directly contact the circuit board.
