Abstract

Apparatus for generating a target physical effect, at least one attribute of which corresponds to at least one characteristic of a digital input signal sampled periodically, the apparatus comprising a multiplicity of electrostatic actuator elements, each comprising a moving element moving between first and second electrodes, the multiplicity of electrostatic actuator elements including Nr first subsets (R-subsets) of actuator elements and Nc second subsets (C-subsets) of actuator elements, wherein a first partitioning of the multiplicity of actuator elements yields the Nr first subsets (R-subsets) and a second partitioning of the multiplicity of actuator elements yields the Nc second subsets (C-subsets); a first plurality of Nr electrical connections (R-wires) interconnecting the moving elements of actuator elements in each R-subset, such that the moving element of any actuator element in each individual R-subset is electrically connected to the moving elements of all other actuator elements in the individual R-subset, and electrically isolated from the moving elements of all actuator elements not in the individual R-subset; a second plurality of Nc electrical connections (A-wires) interconnecting the first electrodes of actuator elements in each C-subset, such that the first electrode of any actuator element in each individual C-subset is electrically connected to the first electrode of all other actuator elements in the individual C-subset, and electrically isolated from all actuator elements not in the individual C-subset; a third plurality of Nc electrical connections (B-wires) interconnecting the second electrodes of actuator elements in each C-subset, such that the second electrode of any actuator element in each individual C-subset is electrically connected to the second electrode of all other actuator elements in the individual C-subset, and electrically isolated from all actuator elements not in the individual C-subset; and a controller electrically.
