摘要： A system includes a core, a plurality of tubes, a plurality of gates, and a plurality of compressors. The core defines a plurality of openings. The plurality of tubes extend radially outward from the core. Each tube of the plurality of tubes includes (i) a first end interfacing with one of the plurality of openings and (ii) an opposing second end. Each gate of the plurality of gates is positioned at a respective opening of the plurality of openings of the core such that the plurality of gates are positioned to selectively prevent a backflow of liquid from the core through the plurality of openings and the first end of the plurality of tubes into the plurality of tubes. Each compressor of the plurality of compressors is associated with a respective tube of the plurality of tubes and is positioned at the opposing second end of the respective tube.

摘要： A power transmission assembly includes a base, a rotating frame rotatably coupled to the base and configured to rotate about an axis, an output shaft coupled to the rotating frame, a weight selectively repositionable relative to the rotating frame, and a weight actuator configured to reposition the weight relative to the rotating frame to move the weight from a subtraction position located at a first height to an addition position located at a second height. The second height is greater than the first height such that a gravitational force on the weight drives the rotating frame to rotate about the axis and drive the output shaft.

摘要： An accessory case for a mobile device includes a housing, a channel, and an input board. The housing has a base wall and a perimeter wall extending away from the base wall, which together define a cavity to receive a mobile device. The channel is formed within the base wall, and extends inward from but not through the base wall to define a pocket that is separate from the cavity. The input board is received within the pocket. The input board is formed by folded segments that have one or more inputs. The input board is configured to transition between a folded position and an unfolded position. In the folded position, a width of the input board is less than a width of the channel. In the unfolded position, the width of the input board is greater than the width of the channel.

摘要： A rotational engine system comprises a rotational engine and a propulsion system. The rotational engine includes an outer ring enclosure, an inner ring component, and a drive gear. The inner ring component includes a piston and a drive gear engagement portion. The piston is configured to travel within the outer ring enclosure along a circumference of the outer ring enclosure. The drive gear engagement portion is configured to rotate as the piston travels along the circumference of the circular shape of the outer ring enclosure. The drive gear is coupled to the drive gear engagement portion of the inner ring component such that rotation of the drive gear engagement portion rotationally drives the drive gear. The propulsion system is configured to deliver propulsive energy to propel the piston along the circumference of the outer ring enclosure.
