Abstract: A battery system may include multiple battery cells grouped into modules. Each battery module may have a diffuser plate to direct the hot gases and molten material that are ejected during cell failure. The gas and material may be directed away from the nearest neighboring cells in the event of a single cell thermal runaway. Residual thermal energy is wicked away, absorbed or contained to keep heat away from the neighboring cells. These and other features may manage the blast energy and residual thermal energy of a single cell failure event. This may prevent a cascading failure of the larger battery system, thereby mitigating the risk of injury to personnel and property.

Abstract: In some embodiments, systems are provided to determine distances to one or more objects, and comprise an image capture system; an angular movement system; an illumination source providing illumination having a time varying amplitude; and a range measurement circuit configured to: obtain, based on at least one of measured and induced LOS angular displacement changes relative to the image capture system, a set of candidate point-spread-functions (PSFs) corresponding to different possible ranges; deconvolve, using the candidate PSFs, at least a region of interest (ROI) in an evaluation image to obtain at least a set of deconvolved ROIs of the evaluation image, each corresponding to one of the candidate PSFs; identify a first candidate PSF that produces a deconvolved ROI resulting in a determined artifact power that is lower than a corresponding artifact power determined from the other candidate PSFs; and determine a distance corresponding to the first candidate PSF.

Abstract: Disclosed are techniques and methods for producing silicon carbide and ceramic matrix composites from hydrocarbons. In one aspect, a method includes preforming a shape using silicon carbide fibers placed into a chamber, evacuating the chamber causing a silicon and polymer slurry to enter the chamber, and pressurizing the chamber causing the silicon and polymer slurry to permeate the silicon carbide fibers. The method includes heating the chamber to cause pyrolysis of the polymer and a hydrocarbon passed into the chamber into carbon and hydrogen gas. The carbon from the pyrolyzed polymer and hydrocarbon provide a coating of carbon on the silicon in the silicon and polymer slurry. The method includes heating the chamber to a higher temperature causing the silicon to melt and react with the carbon to form silicon carbide. The formed silicon carbide and the silicon carbide fibers form the ceramic matrix composite.

Abstract: A system for manufacturing a thermoplastic object may include a robotic arm configured to dispense thermoplastic material, a support apparatus, a computing device and an imaging system. The imaging system may scan thermoplastic material dispensed by the first robotic arm and create a three-dimensional scan model. The model may be compared to a computer model profile to determine if the dispensed material requires adjustment. If the dispensed material requires adjustment, the computing device may adjust the robotic arm or the support apparatus.

Abstract: Features for in-flight recovery of an unmanned aerial vehicle (UAV). A towline may be deployed by a host aircraft in-flight to recover an in-flight target UAV. The towline or portion thereof may be oriented nearly vertical. The towline may have a fitting thereon. A capture mechanism on the target UAV may have one or more deployable flaps that engage with the near vertical towline and fitting. The flaps may stow to secure the target aircraft to the towline and fitting. The host aircraft may then retract the towline to pull in the target UAV to the host aircraft using a hoist system having a winch. A latching system located in a pylon of the host aircraft, which may be under a wing, may have a towline connector that engages with and secures the target UAV. The host aircraft may have multiple hoist systems for deployment and/or recovery of multiple target UAV's.
