  • Patent number: 11943694
    Abstract: A disclosed apparatus obtains emergency data for multiple device types from a plurality of emergency data sources and provides a jurisdictional map view to a plurality of emergency network entities, where each emergency network entity corresponds to a given geographic boundary. The jurisdictional map view corresponds to a respective emergency network entity's geographic boundary. The apparatus determines portions of the emergency data corresponding to emergencies occurring within each respective emergency network entity geographic boundary, and provides location indicators within each respective jurisdictional map view, with each location indicator corresponding to an emergency.

  • Publication number: 20210344217
    Abstract: Datacenter current injection for power management is disclosed. A controller for managing power control modules and current sensing for a datacenter power infrastructure unit is provided. At least three power control modules coupled to the controller are each connected to each phase of a three-phase datacenter power grid. Current sense inputs for each phase of the datacenter power grid are coupled to the controller. At least three battery modules are coupled to a corresponding power control module. The coupling provides an energy path between a battery module and phase of the three-phase datacenter power grid. The coupling is managed by the controller. Each power control module includes a battery charging unit and a current mode grid tie inverter unit. The current mode grid tie inverter unit enables current injection into each phase of the three-phase datacenter power grid at constant voltage and in-phase AC frequency for the phase.

  • Patent number: 10429914
    Abstract: Multi-level data center using consolidated power control is disclosed. One or more controllers communicate with one or more power supplies and sensors to adapt to dynamic load requirements and to distribute DC-power efficiently across multiple IT racks. The distributed DC-power includes one or more DC-voltages. Batteries can be temporarily switched into a power supply circuit to supplement the power supply during spikes in power load demand while a controller reconfigures power supplies to meet the new demand. One or more DC-to-AC converters handle legacy power loads. The DC-to-AC converters are modular and are paralleled for redundancy. The DC-to-AC converters are sourced from the one or more AC-to-DC converters. The AC power is synchronized for correct power flow control. The one or more controllers communicate with the one or more AC-power supplies to dynamically allocate AC-power from the DC-to-AC converters to the multiple legacy IT racks.

  • Patent number: 10128684
    Abstract: Disclosed are systems and methods to provide energy control via power-requirement analysis and power-source enablement. Both demand-side and supply-side techniques are used alone or in conjunction to determine an optimal number of power sources to supply power to one or more loads. When fluctuations in power requirements are present, measures such as decoupling less-critical loads in order to continue delivering power to critical systems and turning on and off power sources as needed to meet the current power demands of a system are implemented. Power sources are periodically deactivated by the system on a rotational basis such that all power sources wear evenly, prolonging the life of the equipment. A scalable architecture that allows the virtualization of power from the underlying hardware form factor is also provided.
