Abstract: A system including a flow straightener for a fuel cell cathode subsystem is provided. The system includes an intake manifold including a tube configured for providing an airflow to a compressor of the fuel cell cathode subsystem. The intake manifold includes an inlet configured for receiving the airflow into the intake manifold. The system further includes a mass air flow sensor disposed upon the intake manifold and a flow straightener disposed within the intake manifold between the inlet and the mass air flow sensor. The intake manifold includes an upstream portion between the flow straightener and the intake manifold inlet. The intake manifold further includes a downstream portion between the flow straightener and the mass air flow sensor. The flow straightener is configured for causing the airflow within the downstream portion to be less turbulent than the airflow within the upstream portion.

Abstract: In exemplary embodiments, methods and systems are provided that include: sensors configured to obtain sensor data for a vehicle having both friction braking and regenerative braking capabilities and coupled to a trailer, the sensor data including: friction braking data as to a vehicle friction braking force for the vehicle; and regenerative braking sensor data as to a vehicle regenerative braking force for the vehicle; and a processor coupled to the sensors and configured to at least facilitate controlling braking of the trailer by providing trailer braking force, via instructions provided by the processor, based on both the friction braking data and the regenerative braking sensor data, with a sensitivity toward the vehicle regenerative braking force such that the trailer braking force is affected differently by the vehicle regenerative braking force versus the vehicle friction braking force.

Abstract: Apparatus are provided for automatic repositioning of fluid nozzles when operating on a workpiece with a tool. The apparatus includes a nozzle assembly configured to convey a fluid to a target zone defined on the workpiece and/or on the tool. The target zone has a location that varies over time. A spring applies a spring force to bias the nozzle assembly toward the target zone, and moves the nozzle assembly as the location of the target zone varies. The nozzle assembly moves to a position relative to the target zone by a combination of action of the spring force and of any hydrodynamic force of the fluid, when moving through the nozzle assembly.

Abstract: An assembly and a method are provided for manufacturing a joined assembly. A method for manufacturing includes fitting together and datuming a beam and a node, wherein at least one of the beam and the node is formed with an aperture, and wherein a cylindrical interface is formed between the beam and node. Further, the method includes advancing a mechanical fastener through the aperture to temporarily hold the beam and the node in an engagement. Also, the method includes injecting a structural adhesive into the cylindrical interface between the beam and the node. The method includes final joining the beam and the node by curing the structural adhesive.

Abstract: A vehicle and a system performing a method of heating a battery of the vehicle. The vehicle includes a battery having a first cell having a first cell type and a second cell having a second cell type, a DC/DC converter having a first side and a second side, and a processor that controls flow of current. The first cell is connected to a first side of a DC/DC converter and the second cell is connected to the second side of the DC/DC converter. A first current is flowed between the first cell and the second through the DC/DC converter to heat the first cell and the second cell during a first heating phase. A second current is flowed between the second cell and the DC/DC converter to heat the second cell during a second heating phase.
