Abstract: A method and three-dimensional printer for compensating for build surface topography. The printer including a controller including executable code to carry out the method of measuring a position of a build surface in a z-axis at a number of points on the build surface when the build surface is pressed against a fixed point on a print head, fitting an x, y-plane to at least three of the number of points on the build surface, leveling the build surface by rotating the x, y-plane around the point of origin in the z-axis, creating a topographic compensation map based on the position of the build surface measured at the number of points on the build surface, and adjusting the distance between the fixed point on the first print head and the build surface during printing referencing the topographic compensation map.

Abstract: Provided herein are various enhanced systems, apparatuses, and techniques for on-surface analysis of celestial or terrestrial surfaces, such as for discovery and analysis of water ice deposits, locations, abundances, and depths. An example herein includes a swarm of spherical payloads sequentially deployed by a deployment host across a large area of a surface to impact the surface, sense properties of the surrounding environment using avionics and scientific instrumentation, and to establish a communication network to collect and transmit collected data.

Abstract: A rover can include a spherical shall and an avionics hub. The spherical shell defines a spherical volume and having an inner surface and an outer surface. The avionics hub is disposed within the spherical volume. The avionics hub includes an avionics shell, a data acquisition unit, and a plurality of motortrain assemblies. The avionics shell is disposed with the spherical volume of the spherical shell. The data acquisition unit is disposed within the avionics shell. Each motortrain assembly includes a motorized wheel extending at least partially through the avionics shell and in contact with the inner surface of the spherical shell, the plurality of motortrain assemblies configured to rotate the spherical shell relative to the avionics shell to move the rover.

Abstract: The present invention provides an extendable handle shaving system comprising an extendable handle assembly and a select shaving blade attachment. The assembly comprises a hand grip portion and a connecting rod. The connecting rod comprises a handle-engaging first rod end, a blade-receiving second rod end, and an S-shaped angular bend intermediate the first rod end and the second rod end. A length-adjusting button is cooperatively associated with the connecting rod for adjusting the effective length of the connecting rod. The select shaving blade attachment may be selected from a disposable straight razor blade assembly and an electric razor head assembly. The shaving system may thus further comprise a power source-recharging base and the extendable handle assembly may comprise a rechargeable power source and electric circuitry. The rechargeable power source and electric circuitry function to selectively and electrically operate the electric razor head assembly.

Abstract: The shaving device includes an extendable handle via a connecting rod with an angular bend whereby the handle may be extended by a connecting rod which fits inside said handle to desired variable length to adjust to different body sizes, such as approximately 12 to 18 inches and the angular bend may also be variable to adjust to different body sizes, such as approximately 30-45 degrees. The characteristic of the shaving device allows shaving hard to reach areas, such as the back. The shaving device may further comprise a disposable shaving blade attachment and switch mechanism for a detachable blade. If desired, the shaving device may further also comprise a detachable shaving cream applicator.

Abstract: A stabilizing wheel assembly has a support frame construction releasably securable to a bicycle and a stabilizing wheel secured to the support frame construction. The latter includes a substantially planar main plate attachable to the bicycle seat stay and the chain stay; a support bar affixed at one of its ends to the main plate and extending generally perpendicularly therefrom; and a fork unit having fork blades straddling the stabilizing wheel and being held on the support bar for a swinging motion in a plane parellel to the main plate. There is further provided an abutting mechansim carried by the support bar and arranged in a path of the swinging motion of one of the fork blades.

Abstract: A bicycle/scooter combination has a support tube assembly including two lower support tubes each having a front terminus affixed to the head tube; a downwardly extending front portion; a rearwardly extending horizontal portion; and an upwardly extending rear portion including a rear terminus of the lower support tubes. The rear terminus is affixed to the bracket shell. There is further provided an upper support tube having an upper terminus affixed to the head tube and a lower terminus attached to the rearwardly extending horizontal portion of the lower support tubes; a horizontal platform supported by the rearwardly extending horizontal portions of the lower support tubes; and chain stays each having a front end affixed to the upwardly extending rear portions of the lower support tubes and a rear end carrying a rear-wheel supporting plate.
