    Abstract: In many embodiments of the invention, a space-based data center includes orbital server modules configured to be deployed in space, each module including a communication subsystem for module-to-module communications to form a data center, tiles arranged in a planar array, where each tile has a layered structure including solar cells forming a layer across a first surface, thermal radiator panels forming a layer across a second surface, electronic components distributed laterally in a layer between the layer of solar cells and the layer of thermal radiator panels, where each electronic component receives power locally from solar cells and rejects heat to the thermal radiator panel beneath it, where a first subset of tiles are compute tiles in which the electronic components include one or more computing processors and memory, and where a second subset of tiles are support tiles in which the electronics components include network switches and energy storage.

    Abstract: A space-based solar power station, a power generating satellite module and/or a method for collecting solar radiation and transmitting power generated using electrical current produced therefrom, and/or compactible structures and deployment mechanisms used to form and deploy such satellite modules and power generation tiles associated therewith are provided. Each satellite module and/or power generation tile may be formed of a compactable structure and deployment mechanism capable of reducing the payload area required to deliver the satellite module to an orbital formation within the space-based solar power station and reliably deploy it once in orbit.

    Abstract: A deformable mirror is configured to be deformed by surface-parallel actuation. In one embodiment, the deformable mirror includes a first piezoelectric active layer on a first surface of a substrate. The first piezoelectric active layer has a substantially uniform thickness across the first surface of the substrate. The mirror also includes a first electrode layer on the first piezoelectric active layer. The first electrode layer has a plurality of electrodes arranged in a first pattern and has a substantially uniform thickness across the first piezoelectric active layer. The mirror may further include a second piezoelectric layer on the first electrode layer, and a second electrode layer on the second piezoelectric layer. The electrodes of the first and second electrode layers are configured to supply a voltage to the piezoelectric active layers upon actuation to thereby locally deform the shape of the mirror to correct for optical aberrations.

    Abstract: Deployable units and systems made of deployable units are described. The units have a retractable brace transitioning from a retracted condition to a deployed condition through a gravity driven movement, a latching arrangement contacting the brace and keeping the brace in position when the brace is in the deployed condition, and a guiding arrangement to guide the movement of the brace. The systems comprise plural deployable units to be arranged in a building structure, each unit to be located in a respective bay per story space of the building structure.
