1. A system which controls an apparatus which comprises a set of actuator elements, each comprising a moving element which moves between first and second extreme positions, wherein each actuator element of the set is comprised in: (a) exactly one first subset out of a plurality of non-empty first subsets (R-subsets) of the set of actuator elements; and (b) exactly one second subset out of a plurality of non-empty second subsets (C-subsets) of the set of actuator elements; the system comprising:
a processor, configured to: determine a maximal number (Nltr) of moving elements which may be released from the first extreme position at a second sampling cycle in a first C-subset which comprises moving elements released from the first extreme position in a first sampling cycle, based on: a number of the moving elements of the first C-subset which were released from the first extreme position in the first sampling cycle; and obtain a number (Ntbr) of moving elements which, if released from the first extreme position during the second sampling cycle, enables production by the apparatus during the second sampling cycle of a physical effect, at least one attribute of which corresponds to at least one characteristic of a digital input signal; and generate one or more control commands for a group of subsets out of the first and the second pluralities of subsets, in response to: (a) Nltr, (b) Ntbr, and (c) a first release-order indication, indicative of an order in which moving elements of the first C-subset are released from the first extreme position; wherein the group of subsets comprising the first C-subset; and an interface for transferring the control commands to the apparatus, thereby resulting in movement of at least one moving element which is comprised in the first C-subset from the first extreme position. |
