Abstract: A server includes a printed circuit board (PCB), an electronic component connected to the printed circuit board, and a chassis connected to the PCB. The chassis includes a first end with a first aperture configured to allow airflow into the server, a second end with a second aperture configured to allow the airflow out of the server after having passed across the electronic component, and a temporary bulkhead that is movable between a deployed position and a stowed position, wherein in the deployed position, the temporary bulkhead is connected to the PCB and extends across the server in a path of the airflow, and wherein in the stowed position, the temporary bulkhead is disconnected from the PCB and is positioned to open the path of the airflow.

Abstract: Embodiments relate to materials and methods for manufacturing the materials for an enclosure that houses one or more electronic devices. In some embodiments, the materials include a tuned micro-lattice that includes one or more metallic materials defining a micro-lattice configuration. In some embodiments, the one or more metallic materials extend over at least a portion of an elastomeric material. In some embodiments, the materials include a tuned composite metallic foam including one or more metallic materials. A first portion of the foam has a first porosity and a second portion of the foam has a second porosity. In some embodiments, the materials for the enclosure are one or more of a gasket and a coating that extends over a least a portion of an interior portion of the enclosure.

Abstract: An land grid array (LGA) or hybrid land grid array (HLGA) includes a socket housing and a plurality of electrical contacts. The socket housing is made of a first material that defines a first dielectric constant. The plurality of electrical contacts extends through the socket housing to electrically couple a printed circuit board on a first side of the socket housing to a processor on a second side of the socket housing. A coating of a second material that defines a second dielectric constant that is higher than the first dielectric constant covers surfaces of a subset of the plurality of electrical contacts.

Abstract: Aspects of this disclosure relate to adjusting the lumen output of a light source. A system may include a light source, a pipe, and at least two light-obscuring elements within the pipe. The pipe may have an inlet port and an outlet port, where the inlet port is configured to be secured to the light source such that all lumens of the light source are directed through an inner passageway of the pipe to the outlet port. The light-obscuring elements may be configured to be moved to reduce a number of lumens of the light source that traverse through the pipe to the outlet port.
