Abstract: A method, or corresponding apparatus, for controlling deformation of a structure, in part, includes applying a command signal at a first signal level to at least one actuator mechanically coupled to a structure, the first signal level known to produce an energy level in the actuator(s) substantially the same as an energy level currently stored by the actuator(s). The method enables the actuator(s) to respond to the command signal by applying an electrical reference to the actuator(s). The method drives the command signal from the first signal level to a second signal level, changing the actuator(s) in at least one dimension as a function of the command signal, which results in a corresponding deformation of the structure. The method electrically disables the actuator(s) by removing the electrical reference, which results in maintaining deformation of the structure defined by energy stored by the actuator(s).

Abstract: A desktop electronic device translates on a desktop from a first position to a second position through use of at least one mobility assembly. The mobility assembly(s) may be integral with the desktop electronic device, connected to the desktop electronic device, or integral with a platform that supports the desktop electronic device. The mobility assembly(s) include at least one primary revolving element and optionally includes at least one secondary revolving element in contact therewith. The primary and secondary revolving elements may be spherically or cylindrically shaped in any combination. A spherical primary revolving element allows the desktop electronic device to translate linearly or non-linearly. Brakes or disengaging mechanisms may be combined with the desktop electronic device, mobility assembly(s), or platform to resist or prevent movement of the desktop electronic device.
