Abstract: A method and system of printable payload extensions of a quadcopter are disclosed. In one aspect, a quadcopter includes an airframe and a central portion of the airframe having at least one of an upper extender mechanism and a lower extender mechanism. The central portion enables users of the quadcopter to design payload extensions that mechanically couple with the quadcopter using a three-dimensional (3D) printing device as long as the payload extensions have a weight less than a maximum payload capacity of the quadcopter. The quadcopter couples with at a set of payload extensions including a hook assembly, an interlocking building block platform assembly, a DSLR camera assembly, a HD camera assembly, and/or a container assembly through the central portion of the airframe.

Abstract: A method and system of printable payload extensions of a quadcopter are disclosed. In one aspect, a quadcopter includes an airframe and a central portion of the airframe having at least one of an upper extender mechanism and a lower extender mechanism. The central portion includes a connection means that enables users of the quadcopter to design payload extensions that mechanically couple with the quadcopter using a three-dimensional (3D) printing device in conformance with the connection means as long as the payload extensions have a weight less than a maximum payload capacity of the quadcopter. The connection means to couple any of a set of payload extensions including a hook assembly, an interlocking building block platform assembly, a DSLR camera assembly, a HD camera assembly, and a container assembly through the central portion of the airframe.

Abstract: A reformer exercise apparatus is disclosed that has a generally rectangular frame. The rail portions of the frame each have an upright outer wall and a hidden outwardly open slot therein. A foot bar support assembly movably carried by each of the outwardly open slots supports the foot bar. Each foot bar support assembly has an elongated slide plate movably supported within the slot, a hook plate fastened to the slide plate, and a foot bar support arm rotatably and slidably fastened to the hook plate. A pair of tubular risers each having a lower and upper roller therein at the head end of the frame direct arm cord ends to a cord retraction assembly mounted on the carriage. The retraction assembly mounted to the carriage releases the cords by pivoting either one of the shoulder stops toward the foot end of the frame.

Abstract: A method, device and system of sidewalk messaging of an autonomous robot are disclosed. In one embodiment, an autonomous robot includes a motherboard comprising a processor communicatively coupled with a memory, a sensory fusion circuitry to execute a command of a sensory fusion algorithm, and a communication circuitry to bi-directionally communicate an instruction between a central server and the autonomous robot. A sidewalk lighting circuitry executes a projection command of a sidewalk messaging algorithm. The sidewalk lighting circuitry autonomously projects a relevant projection of at least one of an operational status message, a directional message, and an advertisement message on a ground of a sidewalk area immediately in front of a present trajectory of the autonomous robot based on the projection command generated by applying the sidewalk messaging algorithm to instructions of at least one of the sensory fusion circuitry, the central server, and the communication circuitry.

Abstract: A method and device of a Skyteboard™ quadcopter are disclosed. In one aspect, a quadcopter includes a first pair of rotors including a first rotor and a second rotor physically enclosed in a peanut shaped airframe, an undercarriage mechanically coupled on a lower side of the peanut shaped airframe, and a second pair of rotors comprising of a third rotor and a fourth rotor mechanically coupled to the undercarriage. The second pair of rotors folds underneath the first pair of rotors such that the first pair of rotors and the second pair of rotors are substantially parallel to each other in a folded mode of the quadcopter. The first pair of rotors is substantially above the second pair of rotors in the folded mode, such that the first rotor is substantially above the third rotor and the second rotor is substantially above the fourth rotor when in the folded mode.

Abstract: A reformer exercise apparatus is disclosed that has a generally rectangular frame. The rail portions of the frame each have an upright outer wall, an integral downwardly slanted inner wall and a hidden outwardly open slot therein between the outer and inner walls. A foot bar support assembly movably carried by each of the outwardly open slots supports the foot bar. Each foot bar support assembly has an elongated slide plate movably supported within the slot, a hook plate fastened to the slide plate, and a foot bar support arm rotatably and slidably fastened to the hook plate. A pair of tubular risers each having an upper roller therein at the head end of the frame direct arm cord ends to a cord retraction assembly mounted on the carriage. The retraction assembly releases the cords by pivoting either one of the shoulder stops toward the foot end of the frame.

Abstract: In one embodiment, a computer device comprises a back cover in the shape of a plate and a basic module where the back cover is removably attachable to and detachable from a basic module of the computing device by the user by an attachment portion. In this manner designs of and on the back cover may be easily customized to the individual tastes of consumers. Another embodiment of the invention is directed to the back cover and the attachment portion of the type described above. An optional front cover may be added and connected to the back cover about a hinge. The front cover can serve as a stand for the computer display when rotated about the hinge away from the display screen. The optional front cover may also be connected to the back cover by a side cover to form a device resembling a hard bound book.

Abstract: A seating unit comprising a base configured to be positioned on a floor, a torsional energy unit connected to the base, a back connected to the torsional energy unit and a seat rotatably connected to the torsional energy unit. The torsional energy unit biases the back to a forward position. The torsional energy unit further limits angular rotation of the seat between a substantially horizontal seating position and a substantially vertical seating position.
