Abstract: A mast assembly for a hydrofoil watersports board system includes a mast, a fuselage adapter, and a watersports board mount. The mast has a fuselage end coupled with the fuselage adapter and a board end coupled with the watersports board mount. The mast includes a side profile having width dimensions in portions of the mast that are greater than at its fuselage end and its board end. The fuselage adapter couples to a fuselage of a lower assembly, which further includes a front wing and a tail wing. The watersports board mount couples to a watersports board. The mast includes internally integral stringers to improve structural integrity.

Abstract: A battery pack and battery pack chassis are described. The battery pack includes a chassis that is configured to position multiple cells proximate to one another within the pack, while also providing areas through which a potting compound can flow and contact the cells. For example, the chassis can include spacers or ribs that separate the cells, in some cases in asymmetric configurations, such that the potting compound contacts the outer surface of each battery cell within the pack. The chassis, in some cases, can also facilitate the connection of a bus bar between battery cells.

Abstract: Systems, methods, and apparatus for storing perishable items under reduced pressure conditions. Total atmospheric pressure within a vacuum chamber containing a perishable item is reduced below a total pressure limit. Oxygen partial pressure and total pressure within the vacuum chamber are monitored. When oxygen partial pressure falls below a lower oxygen partial pressure limit, an oxygen-containing gas is admitted to raise oxygen partial pressure above the lower oxygen partial pressure limit. When the total atmospheric pressure reaches or exceeds the total pressure limit, total pressure is once again reduced. The vacuum container or chamber comprises a section of cylindrical pipe open at both ends, a first end cap and a second end cap, and formed of a plastic material. Notwithstanding that the pipe and end caps are formed of plastic, they are formed with a structure capable of withstanding pressure created by a high vacuum in the vacuum container.

Abstract: A vacuum container for containing perishable items in controlled, reduced pressure, atmospheric conditions is provided. The vacuum container includes a section of generally cylindrical pipe open at both ends and formed of a plastic material. A first end cap is detachably secured to one end of the pipe to form a vacuum resistant seal between the first end cap and the pipe. A second end cap detachably secured to the other end of the pipe to form a vacuum resistant seal between the second end cap and the other end of the pipe. Preferably, the pipe and end caps are all formed of a plastic material capable of withstanding the pressures created when a high vacuum is formed in the chamber.

Abstract: A system and method for storing perishable items under controlled atmospheric conditions is provided. Total atmospheric pressure within a vacuum chamber containing the perishable items is reduced to below a predetermined total pressure limit. Oxygen partial pressure within the chamber is monitored. When the Oxygen partial pressure falls below a predetermined lower Oxygen partial pressure limit, an Oxygen-containing gas is admitted to the vacuum chamber to raise the Oxygen partial pressure above the lower Oxygen partial pressure limit. Total atmospheric pressure within the chamber is also monitored. When the total atmospheric pressure reaches or exceed the predetermined total pressure limit, total pressure within the vacuum chamber is once again reduced below the predetermined total pressure limit.

Abstract: Methods, apparatus, and system to manage an atmosphere and/or an antimicrobial inside a vacuum chamber or container, including via at least one of valves, sensors, manifold, antimicrobial delivery unit, antimicrobial sachet, vacuum pump, and an atmosphere control.

Abstract: A system and method for transporting and storing post-harvest fruits, vegetables and other perishable commodities under controlled atmospheric conditions is provided. One or more transportable vacuum containers are packed with the perishable commodity. Thereafter, the controlled atmospheric condition is created within the container. The atmospheric condition is maintained while the container is transported from one location to another. Part of the controlled atmospheric condition includes the formation of a vacuum within the container. Internal structure is provided within the container to resist collapse of the container when the vacuum is formed therein. A plurality of containers can be provided. A central control, coupled to each of the containers can be provided to maintain the desired atmospheric condition within each of the containers.

Abstract: A portable electronic device, having a single piece housing to carry operational components having a front opening, an integral bottom and sidewalls that cooperate to form a cavity in cooperation with the front opening. The operational components can include a display to present visual content disposed within the front opening and having an outermost protective layer, a main logic board that extends along a central portion of the cavity having a size and shape that bisects the cavity into a first portion and a second portion each having substantially the same size and shape, a power storage system supported at the bottom wall and comprising a first power storage unit located in the first portion and second power storage unit located in the second portion, each being coupled to the main logic board, and self-contained audio components positioned at each corner of the single piece housing.

Abstract: Hydrofoil assemblies that can be attached to a board used for watersports are disclosed herein. A hydrofoil assembly may include, for example, a mast a coupleable to a fuselage at a lower portion of the mast and coupleable to a board at an upper portion of the mast, and front and rear wings coupleable to the fuselage. A hydrofoil mast may include, for example, first and second composite sections bonded together to form a hollow load-bearing mast structure. Leading and trailing elements made of a material that is softer than the composite mast structure may be adhered to the mast structure to complete a hydrodynamic profile of the mast.

Abstract: An enclosure for an electronic device is enclosed. The enclosure includes rib structures configured to improve structural support to prevent damage and to dissipate vibration throughout the enclosure. The rib structure can receive a speaker module and a cap member. The rib structure and the speaker module can combine to form a three-dimensional volume allowing the speaker module in which the speaker module may project sound, thereby enhancing acoustic performance. Also, the cap member may be adhesively attached to the rib structure to provide additional structural support against vibration and abuse caused by load forces associated with a drop event.

Abstract: A vehicle body structure, includes a structural pillar that is located adjacent to a passenger compartment. The structural pillar has an elongate aluminum extrusion that has a peripheral wall that defines a closed cross-sectional shape. The peripheral wall has at least a first portion that is oriented toward the passenger compartment, and a stiffening structure that is connected to the first portion of the elongate aluminum extrusion.

Abstract: Carbon fiber bicycle wheels are formed from parts cut from carbon fiber cloth and then joined together to form a rim, sidewalls, spokes, flanges and a center tunnel on which the flanges are mounted. The parts are then assembled, bonded together, and cured to form a wheel. During assembly, the spokes and the wheel are placed in tension by moving the flanges outwardly on the center tunnel after assembly and then bonding them in place to stiffen and strengthen the wheel. The spokes of the drive side of the rear wheel are specially shaped to accommodate torque transfer forces generated by pedaling.

Abstract: This application relates to systems, methods, and apparatuses for reducing bending stresses and tension from damaging components of a computing device. A component of the computing device can be connected to a spacer that can distribute impact forces and resist bending when an impact force is applied to the computing device. Additionally, a bracket can be connected to a circuit board of the computing device to further help distribute impact forces and resist bending. The bracket can be ring shaped and surround components connected to the circuit board to intercept impact forces from contacting the components.
