An aircraft may include at least one secondary power system requiring secondary power, at least two main engines, and at least three non-propulsive utility power (NPUP) generation systems. The NPUP generation systems may each be configured to provide full-time secondary power during operation of the aircraft. The NPUP generation systems may be configured to provide at least a portion of the secondary power required by the secondary power system.

Non-propulsive utility power (NPUP) generation system for providing secondary power in an aircraft

The present disclosure provides a system, method, and apparatus for battery management. The disclosed method involves current balancing through sinking and/or sourcing current, by at least one virtual cell, for battery cells in a battery pack based on available current and capacity of the battery cells. In one or more embodiments, at least one virtual cell is capable to sink and/or source current for at least one degraded battery cell or at least one dead battery cell.

A thermal energy harvester and power conversion system employs a bleed air duct containing the flow of high temperature air from an engine. A lower temperature air source is included with an energy conversion device having a hot interface operably engaged to the bleed air duct and a cold interface operably engaged to the lower temperature air source. The energy conversion device generates electrical power from a thermal gradient between the bleed air duct and the lower temperature air source and the electrical power is routed to a power feeder.

A system, method, and apparatus for virtual cells for battery thermal management are disclosed. The disclosed method involves sensing, with at least one temperature sensor, a temperature of at least one battery cell in a battery pack. The method further involves sensing, with at least one current sensor, at least one current within the battery pack. Also, the method involves determining, with a battery thermal management system (BTMS) controller, if the temperature of any of the battery cells in the battery pack exceeds a temperature limit (T). Further, the method involves activating, with the BTMS controller, at least one virtual cell to provide current or sink current for at least one of the battery cells in the battery pack that exceeds the temperature limit.

A method and apparatus for managing a location. Soil sensor units are deployed in the location in a forest from a group of aerial vehicles. Information is generated about a number of soil conditions in the location in the forest using the soil sensor units in the location. The information is transmitted from the soil sensor units to a remote location for analysis.

Forest sensor deployment and monitoring system

A method and apparatus of managing a forest. A forestry management system comprises a forestry manager. The forestry manager is configured to receive information about a forest from a group of autonomous vehicles, analyze the information to generate a result about a state of the forest from the information, and coordinate operation of the group of autonomous vehicles using the result.

Forestry management system

A method and apparatus for managing icing of a plurality of transmission lines in a power transmission system. A power transmission system comprises a plurality of transmission lines and a control system. A first amount of power flows into the power transmission system through the plurality of transmission lines and a second amount of power flows out of the power transmission system through the plurality of transmission lines. The control system is configured to change a flow of power through the plurality of transmission lines such that icing of the plurality of transmission lines is managed. The first amount of power flowing into the power transmission system and the second amount of power flowing out of the power transmission system remains substantially constant during the change in the flow of power through the plurality of transmission lines.

Method and apparatus for anti-icing and deicing power transmission lines

A method and apparatus comprising an agent. The agent is configured to receive information from an electrical power grid. The agent is further configured to identify an event from the information. The agent is further configured to classify the event. The agent is further configured to determine whether to initiate an action based on a classification of the event. The agent is further configured to initiate the action in response to a determination to initiate the action.

Event processing system for an electrical power system

A method and apparatus comprising a switch and a charging management module. The switch is configured to control an electrical connection between a charging device for a battery and a power source. A current flows from the power source through the charging device to the battery to charge the battery when the electrical connection is present between the charging device and the power source. The charging management module is configured to identify a period of time for charging the battery and to control the switch to electrically connect the charging device for the battery to the power source during the period of time identified for charging the battery.
