Abstract: A multiplexer (MUX) driver system controls a deformable mirror, in part, by enabling and disabling individual or multiple actuators, mechanically coupled to the deformable mirror, through use of switches (e.g., solid-state switches) electrically coupled between the actuators and a reference node. In operation, the driver system enables actuator(s) by closing respective switch(es) and driving the enabled actuator(s) to deform respective portions of the deformable mirror in a controlled manner. The driver system disables the actuator(s) by opening the respective switch(es) to decouple the actuator(s) from the reference node. The switches, in the open state, prevent respective actuators from discharging, thereby allowing a desired surface figure of the deformable mirror to be maintained for long periods of time without having to refresh the actuators.

Abstract: Desktop mobility is provided for a desktop electronic device by at least one mobility assembly to translate the desktop electronic device from a first position to a second position on a desktop. The mobility assembly(s) may be integral with a housing of the desktop electronic device, connected to the desktop electronic device, or combined with a platform used to provide mobility for the desktop electronic device. The mobility assembly(s) include at least one primary revolving member and at least one secondary revolving member in contact therewith. The primary and secondary revolving members may be spherically or cylindrically shaped, independently. The mobility assembly(s) may be selectably engaged with and disengaged from the desktop. Additionally, various braking mechanisms may be selectably applied to restrict movement of the desktop electronic device.
