Abstract: Apparatuses, systems, and methods for providing wind-resilient solar panel racking structures. The solar panel racking structures having first and second upper panel mount assemblies, first and second base assemblies, and first and second sets of solar panels. The upper panel mount assemblies and base assemblies linked by cross-braces and together forming a tent-like structure for supporting the solar panels at an angle.

Abstract: Apparatuses, systems, and methods for providing wind-resilient solar panel array fields. The solar panel array fields may have perimeter solar panel racking structures and core solar panel racking structures. The perimeter solar panel racking structures forming at least a perimeter around the core solar panel racking structures to help shield core solar panel racking structures and reduce wind forces applied to the core solar panel racking structures. The perimeter solar panel racking structures may be rigid and may be more wind tolerant than the core solar panel racking structures.

Abstract: A method of treating COVID-19 in a human in need thereof. The method comprises administering a tetracycline compound in an amount that is effective to treat COVID-19, but has substantially no antibacterial activity.

Abstract: A dual-diaphragm loudspeaker driver assembly can include a multiple pole magnet structure, and first and second pole piece assemblies can be provided on opposite first and second sides of the multiple pole magnet structure. In an example, each pole piece assembly defines an airgap over a polarity transition region on a respective side of the magnet structure. First and second voice coils can be provided in respective ones of the airgaps, wherein each of the voice coils is coupled to a respective diaphragm assembly, and at least one acoustic tuning port can be configured to provide a damped acoustic communication path between first and opposite second sides of each diaphragm assembly.

Abstract: Apparatuses, systems, and methods for a self-balanced PV array that can withstand extreme loads (e.g., wind, snow, etc.) applied across large surface areas using one or more supports configured along just a single axis. Generally, the load balancing mechanism comprises, in one embodiment, a configuration of support struts that are attached to the PV array at various points depending on the configuration of the PV array and the expected loads. The struts are generally configured to provide two work points that are distributed above and below the ground, pedestal or other connection of the PV array to the surface condition.

Abstract: An actuator for a tire inflation system, the actuator having a first component that has a first fluid passage and a second component having a second fluid passage and a sealing surface for sealing engagement with a rotatable component of a wheel assembly. The second component is movable relative to the first component between a first position, in which the first fluid passage is isolated from the second fluid passage and the sealing surface is spaced from the rotatable component, and a second position, in which the first fluid passage is in fluid communication with the second fluid passage and the sealing surface is in sealing engagement with a rotatable component.

Abstract: A tire inflation system having a spindle that is configured to support a wheel bearing. A passage for routing pressurized gas may be provided with the spindle or with a sleeve that may be disposed on the spindle.

Abstract: An axle assembly having a ballast insert assembly and a method of control. The ballast insert assembly may have an inflatable bladder that may be disposed in a cavity. The volume of lubricant in the cavity may be greater when the inflatable bladder is deflated than when the inflatable bladder is inflated.
