Publication number: 20240092633Abstract: An MEMS has a substrate and a cavity arranged in the substrate. A movable element is arranged in the cavity, configured to interact with a fluid arranged in the cavity, wherein a movement of the fluid and a movement of the movable element are causally related. A first opening which connects the cavity to an environment of the substrate causes a first phase offset of a first periodic oscillation which is causally related to the movement of the movable element when passing through the first opening. A second opening which connects the cavity to the environment of the substrate causes a second phase offset, different from the first phase offset, of a second periodic oscillation which is causally related to the movement of the movable element when passing through the second opening.Type: ApplicationFiled: September 14, 2023Publication date: March 21, 2024Inventors: Anton MELNIKOV, Jörg AMELUNG, Bert KAISER, Michael STOLZ

Patent number: 9226348Abstract: A light-emission device with a two-dimensional OLED element and an encapsulation element for protecting the OLED element. The light-emission device furthermore has a support, on which the OLED element is arranged in such a way that the encapsulation element points toward the support, and an electrical conductor element for an electrical connection between the support and the OLED element. wherein the electrical conductor element is elastic in a normal direction to the OLED element. By way of example, the conductor element can be helical. As a result of the elastic property thereof, the conductor element can absorb mechanical tension while ensuring reliable electrical contacting. Hence, this can reduce or even avoid the risk of the electrical connection between the support and the OLED element being disadvantageously influenced or impaired by forces which can occur when handling the light-emission device or which can be generated by temperature variations.Type: GrantFiled: April 2, 2013Date of Patent: December 29, 2015Assignee: TRODONIC GMBH & CO.
