Abstract: The present disclosure relates to systems and methods for screening a formulation of a material being printed in an additive manufacturing process, in situ, to enable rapid analysis, modeling and modification of at least one characteristic associated with the material formulation. In one embodiment the system includes a computer and an experimental planning software module that includes a historical database of sample material test results, a machine learning software module, and a new batch formulation generation software module. The experimental planning software module enables new material formulations to be determined in situ and in real time, using one or more machine learning models, and new material samples to be printed in accordance with newly determined material formulations, for closer inspection and evaluation of at least one desired characteristic of the sample materials.

Abstract: Screening for screening a material includes: providing active mixing direct-ink-writing of the material, providing in situ characterization substrates or probes that receive the material, and providing active learning planning for screening the material. The providing active mixing direct-ink-writing of the material prints five to ten films. The providing in situ characterization substrates or probes includes printing five to ten films on the substrates or probes with a first set of constituents. The providing active learning planning for screening the material includes providing machine learning that takes the first set of constituents and uses the first set of constituents to dictate a next batch of films to achieve improved additional sets of constituents.

Abstract: Mounting blocks for securing items to a tire are secured by a tensioner wrapped around the tire and mounting blocks. Tensioning blocks maintain tension in the tensioner. The tensioner may be a pair of cables passing through grooves in the mounting blocks. The mounting blocks may define recesses over which the cable passes. Straps may pass around the cable in a recess to secure a pouch over a center of the tire. The cables may include widened portions that fit within widened portions of slots defined in the tensioning blocks. The mounting blocks and tensioning blocks may be identical but used differently. The mounting blocks may define openings for receiving straps securing items to the mounting blocks. Straps may be used in the place of cables and a pouch secured to the mounting blocks using other structures on the mounting blocks.

Abstract: A collapsible travel case includes a plurality of panels that are each non-removably secured to at least one other panel of the plurality of panels. Each panel of a subset of the panels may be removably secured to another panel of the subset of panels such that the plurality of panels define a substantially cuboid shape. A top panel may define a top opening with a closure mechanism. A bottom panel may be foldable and insertable within the top opening with other panels of the plurality of panels folded between the top panel and the bottom panel. The bottom panel may include a retractable stiffening element. Panels may define openings through which flaps secured to other panels may insert and be secured within using fastening material.

Abstract: A sheet of material has a left panel secured to the left edge and a right panel secured to a right edge such that a pouch is formed at one end of the sheet of material with a roll panel portion of the sheet extending outwardly form the pouch. Storage structures, such as pouches and tool rolls may secure to the roll panel removably or non-removably. The storage structures and roll panel which may be rolled up and placed within the pouch. A perimeter of the pouch may include a closure mechanism, such as a cord and cord lock for constricting the opening of the pouch. A suspension portion may secure to the roll panel for hanging the roll panel and pouch during use.

Abstract: Fastening patches with fastening material (VELCRO, 3M DUAL LOCK) on both surfaces each include a column with outwardly extending tabs. Fastening patches secure to a backing layer and the tabs of fastening patches may secure to one another to form loops for securing items. The backing layer may include fastening material for securing to an inner surface of luggage. The arrangement of the tabs may correspond to the MOLLE or PALS standard. Fastening patches may include smaller anchor tabs at the top and bottom of the column and be secured to luggage without stitching.

Abstract: The present disclosure relates to a hitch-mounted apparatus for use in conjunction with a vehicular hitch receiver to efficiently transport one or more payloads. In particular, the hitch-mounted apparatus may include first and second support arms that are adjustably connected to a connecting member. In some embodiments, each of the first and second support arms and the connecting member include at least one mounting surface defining one or more slots. Utilizing the one or more slots, at least one of the first and second support arms can slide relative to the connecting member. Similarly, upper and lower retention mechanisms for securing a payload can slide relative to the respective first and second support arms. Further, via the one or more slots of the connecting member, lever locks can secure or loosen fasteners at a pivot joint coupling the connecting member and a hitch tube inserted into a vehicular hitch receiver.

Abstract: A travel pouch includes a plurality of panels defining a cuboid shape. Within the travel pouch is a sleeve including divider portions with fastening material that may be joined together to form a divider across the sleeve. The divider portions may each include multiple panels. Fastening material on the sleeve may facilitate folding back the divider portions when not in use. A panel may include a cable opening, an end portion of which is covered with an outer panel.

Abstract: An architecture for powering systems on an aircraft has a gas turbine engine including a main compressor, a combustor, and a turbine. The turbine powers the main compressor, and further powers a propulsor. The turbine is operably connected to drive a generator. The generator is connected to store generated power at a battery. The battery is connected to provide power to a motor from the propulsor such that the propulsor can be selectively driven by both the motor and the turbine. A bleed air control system and a tap for selectively tapping compressed air from the main compressor, and a control valve for delivering at least one of the tapped compressed air or a compressed alternative air to bleed systems on an associated aircraft. An electric bleed compressor selectively compresses the compressed alternative air. The electric bleed compressor is powered by the battery.

Abstract: Passive reduction of internal jet engine component temperature in supersonic and hypersonic vehicles results from use of nanocomposite optical ceramic materials between the heat-generating portions of each jet engine and the ambient environment, allowing heat dissipation from the jet engine components directly to the ambient environment. A propulsion-airframe integrated scramjet aircraft includes a jet engine and an airframe supporting the jet engine, with at least a portion of the airframe between a heat-generating portion of the jet engine and an ambient environment comprising a nanocomposite optical ceramic material in the form of a panel or a grid of windows each supported within a frame. The nanocomposite optical ceramic material portion of the airframe disposed between the heat-generating portion of the jet engine and the ambient environment is infrared-transparent, and may transmit at least 75% of heat energy from the heat-generating portion of the jet engine to the ambient environment.
