Abstract: Provide for herein is an apparatus that includes multiple printed circuit board (PCB) layers and a via assembly. The via assembly includes a signal via extending through the multiple layers, and the signal via is configured to transmit a signal between the layers. The via assembly also includes a capacitive structure connected to the signal via to adjust an impedance of the via assembly along the via assembly. The capacitive structure is physically and electrically separate from other components of the PCB.

Abstract: In some embodiments, an integrated circuit (IC) includes multiple packages that are separate from one another. Each package includes a pad, and a core via is electrically coupled to the pads of the separate packages to electrically couple the packages to one another. At least one of the pads includes an oblong shape to match its impedance with the impedance of the core via.

Abstract: A method that includes receiving an indication at a modular electronic system of initiation of online removal for a module removably inserted into a slot of the modular electronic system, increasing a fan speed at the modular electronic system before the module is removed, monitoring an internal temperature at the modular electronic system, and providing an indication that the module is ready for removal upon reaching a specified cooling state at the modular electronic system based on the temperature monitoring. A panel on an adjacent module is opened and extends into the slot upon removal of the module to substantially block airflow bypass from the slot and maintain cooling within the modular electronic system. An apparatus and logic are also disclosed herein.

Abstract: Presented herein are techniques for balancing energy usage. A method can include obtaining energy consumption patterns of a plurality of devices that consume energy in an environment from a plurality of data sources. The method can further include analyzing operational patterns of the plurality of devices that are dynamically controllable and associated with the environment to generate device data. The method can further include building and maintaining multiple domain ontologies for sustainability profiles. The method can further include developing a profile for energy consumption for at least one device of the plurality of devices, wherein the profile is based on the energy consumption patterns, the device data, and at least one sustainability profile of the multiple domain ontologies.
