  • Patent number: 11459229
    Abstract: An MMS includes a substrate, an element movable with respect to the substrate and a frame structure. A first pair of springs is arranged between the substrate and the frame structure along a first spring direction. A second pair of springs is arranged between the movable element and the frame structure along a second spring direction. The frame structure is configured to generate tensile stress in the second pair of springs at tensile stress acting in the first pair of springs.
    Type: Grant

  • Patent number: 11079411
    Abstract: An electromechanical component and an electromechanical component arrangement for proving the existence of a potential difference which consists of a first electrode, a second electrode and a proving structure. The proving structure is configured to be deflected in the event of there being a potential difference. In addition, an electromechanical component is configured to generate a useful effect. A method implements operation of an electromechanical component for proving the existence of a potential difference, other methods implement operation for performing a functional test on the electromechanical component.

  • Patent number: 10807859
    Abstract: Embodiments of the present invention provide an MEMS actuator with a substrate, at least one post attached to the substrate and a deflectable actuator body that is connected to the at least one post via at least one spring, wherein, during electrostatic, electromagnetic or magnetic force application, the actuator body takes a second position starting from a first position by a tilt-free translational movement, wherein the first position and the second position are different, and wherein in a top view of the MEMS actuator the actuator body is arranged outside an area spanned by the at least one post.

  • Patent number: 6259550
    Abstract: A structure for the phase modulation of light (32) incident upon said structure comprises a mirror (40), a deformable and transparent dielectric (36) disposed on the mirror (40), at least two electrodes (41; 42; 41a, 41b, 42; 50, 50′) having one or several fixed potentials and being adapted to have one or more control voltages applied thereto for generating an electric field (58) in at least a partial region of said dielectric (36), thereby changing the optical path length of the light passing through said dielectric (36) with respect to a state of the dielectric (36) in which the electric field is not applied thereto. An arrangement of a plurality of such phase-modulating structures applied on a CMOS active matrix constitutes a very large scale integrated spatial light modulator.

  • Patent number: 5169617
    Abstract: A method for treating produced gypsum and, in particular, a method for treating flue-gas desulfurization gypsum forms highly active, modifiable gypsum binders of high strength with simultaneously drying, deagglomerating and dehydrating. Pursuant to the invention, produced gypsum (flue-gas desulfurization gypsum), with a particle size ranging up to 200 .mu.m, to which 10% by weight of milled natural gypsum is optionally added, is dehydrated at a material temperature of 335.degree. to 363.degree. K. and at a pressure ranging from 2.5 to 8 kpa, the dehydration being concluded when anhydrite III constitutes 50% to 100% by weight.
