Patent number: 11016516Abstract: Energy packet switches (EPS) employing supercapacitors as storage provide aggregation and delivery of energy to users based on shared-capacitance in a digital power grid. The EPS aggregates energy from one or multiple energy sources, stores and dispatches the energy in discrete amounts as energy packets to one or multiple users. The payload of the energy packet is adjusted by the voltages of the supercapacitors which are used as energy containers for both the EPS and the users. The EPS has a control plane where data transmitted is used to control the operation of the EPS, and a power plane to receive and transmit energy between ports. The power and data planes work in parallel and with a parallel data network. Control and management of the EPS are based on a request-grant transport protocol. The data network is used to receive energy requests and grants, and a granting scheme is used to select which loads are granted energy.Type: GrantFiled: July 30, 2019Date of Patent: May 25, 2021Assignee: New Jersey Institute of TechnologyInventors: Roberto Rojas-Cessa, Haim Grebel, Zhengqi Jiang

Patent number: 11009928Abstract: Techniques for optimizing airflow in a network device are provided. In one set of embodiments, a network device can identify one or more device components whose temperature thresholds may be adjusted to be higher (or in other words, more aggressive) than their normal values. The network device can then increase the temperature thresholds for those identified components and use the increased thresholds as static inputs to a fan control algorithm of the device. In another set of embodiments, the network device can check the current airflow within the device on a periodic basis. If the current airflow does not meet an airflow requirement, the network device can incrementally increase the temperature thresholds of the identified components, provide the increased thresholds to its fan control algorithm, and subsequently re-check the current airflow. These steps can repeat until the current airflow meets the airflow requirement.Type: GrantFiled: June 12, 2019Date of Patent: May 18, 2021Assignee: Arista Networks, Inc.Inventors: Geoffrey Hanson, Vincent Cridlig, Edward Chien

Patent number: 11009934Abstract: To eliminate the adverse effects of power swings in a large scale computing system during the life cycle of an application or job, control of several operating characteristics for the collective group of processors is provided. By providing certain levels of coordination for the many processors utilized in large scale computing systems, significant and abrupt changes in power needs can be avoided. In certain circumstances, this may involve limiting the transition between several C-States of the processors involved and the overall power transitions for a large scale system are not detrimental and do not create issues for the data center or local power utility. Some cases will require stepped transitions between C-States, while other cases will include both stepped and modulated transitions. Other cases will incorporate random wait times at the various transitions in order to spread the power consumption involved.Type: GrantFiled: September 19, 2018Date of Patent: May 18, 2021Assignee: Hewlett Packard Enterprise Development LPInventors: Josh Williams, Steve Martin, Clark Snyder, David Rush, Matthew Kappel
