Abstract: Disclosed are systems and methods for a power control system for a vehicle having multiple power sources. The power control system may include a plurality of sensors associated with one or more power sources and a microcontroller configured to receive a plurality of signal inputs, wherein the microcontroller selects a power state for the power control system based at least in part on the plurality of signal inputs from the plurality of sensors. The power state may be selected from a group including a first power state, wherein power is provided to a critical power subsystem, an essential power subsystem, and an auxiliary power subsystem, a second power state, wherein power is provided to the critical power subsystem and the essential power subsystem of the vehicle, and a third power state, wherein power is provided only to the critical power subsystem of the vehicle.

Abstract: Apparatuses and methods for optimizing air flow in respiratory protective devices are provided. For example, an example respiratory protective device may include a pressure sensor component, at least one fan component, and a controller component. In some example, the controller component is configured to receive a plurality of air pressure indications from the pressure sensor component, calculate a breath pattern indication based on the plurality of air pressure indications, determine a forward rotation speed value for the at least one fan component, and determine a forward rotation start signal transmission time point and a forward rotation stop signal transmission time point for the at least one fan component.
