Abstract: A system which controls a group of multiple arrays of actuator elements, each of the actuator elements including a moving element which moves between a first and a second extreme positions; the system including: a controller, configured to generate control commands for at least one array of the multiple arrays in each individual cycle out of a series of sampling cycles, based on obtained information; and (b) an interface configured to transfer the control commands to the at least one array, thereby resulting in releasing from the first extreme position during the intended cycle of at least one moving element that is included in the at least one array; wherein release of all moving elements of at least one restrained array out of the multiple arrays is prevented during the intended cycle.

Abstract: The present disclosure provides a method for use in manufacturing a microsystem, the method comprising forming an array of pillars in a thickness of a substrate, an area surrounding the array of pillars defining a cavity in the substrate; transforming at least some of the pillars into a sacrificial material; and depositing a sacrificial material layer using a non-conformal deposition process to fill up the cavity while enclosing hollow channels between the pillars of the pillars array, thereby obtaining a cavity filled with an etching facilitator arrangement.

Abstract: A system includes an apparatus and a processor. The apparatus includes a set of actuator elements that move between two positions. Each actuator element is comprised in: exactly one first subset out of a plurality of non-empty first subsets and exactly one second subset out of a plurality of non-empty second subsets. The processor is configured to 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 number of moving elements which, if released from the first extreme position during a second sampling cycle, enables production by the apparatus during the second sampling cycle of a sound.

Abstract: Actuator apparatus for generating a physical effect, at least one attribute of which corresponds to at least one characteristic of a digital input signal sampled periodically in accordance with a sampling clock, the apparatus comprising at least one actuator device, each actuator device including an array of moving elements, wherein each individual moving element is operative to be constrained to travel alternately back and forth along a respective axis responsive to an individual first electrostatic force operative thereupon, wherein each moving element has an at-rest position and is driven away from its at rest position solely by the first electrostatic force; and at least one electrode operative to apply a controlled temporal sequence of potential differences with at least one individual moving element from among the array of moving elements thereby to selectably generate the first electrostatic force; and a controller operative to receive the digital input signal and to control at least one of the at least one electrode and the individual moving element to apply the sequence of potential differences.
