Abstract: An orbital satellite has a bus formed of a bus module and a payload module. Both the bus module and the payload modules may include a pair of panels integrally formed at an angle of for example 90° with respect to each other. Components and electronics supporting the satellite systems may be mounted on the panels of the bus and payload modules. Heat generated by the components and electronics are conducted between panels of the bus module and/or payload module. Sufficient heat transfer between panels occurs as a result of their being integrally formed with each other.

Abstract: A painting tool for painting a vehicle wheel is disclosed. The tool includes a base and a plurality of idler wheels rotatably coupled to the base. The wheels are disposed about the base to rotatably support a workpiece. A motor is coupled to the base and includes a motor output disposed to engage the workpiece and to rotate the workpiece on the plurality of idler wheels about a workpiece axis. A mask is operatively coupled to the base. The mask is movable between an engaged position wherein the mask obscures a portion of the workpiece and a disengaged position wherein the mask is disposed away from the workpiece. A method of painting a vehicle wheel is also disclosed.

Abstract: A spacecraft having a body whose shape is not uniform along its major axis. The spacecraft body has a lower portion and an upper portion that are disposed along a major axis of the body. The upper portion is smaller in cross section along the major axis than the lower portion. The nonuniform body shape maximizes various dependent and independent features of the spacecraft. This allows additional equipment to fit within the available launch vehicle volume, increased thermal radiator area/capacity, and increased payload capability, and provides for more and/or larger antennas, for example. The nonuniform features of the spacecraft body thus allow for unique stowage of various appendages on the spacecraft body, and in particular, allows the use of four-sides of the spacecraft structure to stow antennas.

Abstract: An electric motor for driving a mechanical load at variable speed and constant torque includes a stationary housing containing a magnetic field rotor driven by alternating current and surrounding a drive rotor. The rotors rotate in opposite direction when the drive rotor is coupled to a load. The motor can be of induction or synchronous type.
