Abstract: The present invention relates to a device and method for shifting a fluid within a fluid channel. The device comprising: - a fluid channel (20) comprising at least one chamber (15), each chamber (15) being filled with a fluid (12) comprising an electrolyte and having at least two inlets (17), wherein each inlet (17) has a cross-section which is smaller than a cross-section of the at least one chamber (15); - a sealing control element (13) being enclosed in the fluid (12) of the fluid channel (20) for sealing the at least one chamber (15) and controlling a shift of the fluid (12) within the fluid channel (20) in response to a control signal (30); and - at least one pair of electrodes (8) arranged such that the electrodes (8) are in fluidic contact with the at least one chamber (15) for causing, in response to the control signal (30), an electrocapillary force acting on the sealing control element (13); wherein the sealing control element (13) has a surface tension which is higher than a surface tension of the fluid (12), such that in the absence of the control signal (30) at least a portion of the sealing control element (13) is trapped in one of the at least one chamber (15) due to an intrinsic capillary force, thereby sealing said one of the at least one chamber (15).

Abstract: Die Erfindung betrifft eine Vorrichtung, ein System und ein Verfahren zur Erzeugung einer dreidimensionalen Struktur in einem Medium (1). Die Vorrichtung weist auf: eine Aufnahmeeinrichtung (10), welche dazu eingerichtet ist, ein Medium (1) aufzunehmen, welches eine Vielzahl von in mehreren Zeilen parallel zueinander angeordneten Stiften (12) aufweist, welche in Längsrichtung einzeln verschiebbar sind, und mindestens einen Schreibkopf (20), welcher mehrere in einer Zeile angeordnete, einzeln ansteuerbare Positionierstifte (21) aufweist, welche dazu eingerichtet sind, jeweils eine vorgegebene Position bezogen auf die Längsrichtung einzunehmen und auf eine zu beschreibende Zeile des von der Aufnahmeeinrichtung (10) aufgenommenen Mediums (1) zu bewegt zu werden und dabei die in der zu beschreibenden Zeile angeordneten Stifte (12) des Mediums (1) entsprechend der jeweils eingenommenen Position der Positionierstifte (21) in Längsrichtung zu verschieben.

Abstract: A refreshable Braille display system (100) includes a plurality of Braille cells (101), an interface (103), and a microcontroller unit (104). Each of the braille cells (101) includes an array of openings such that each opening (101a) houses a Braille dot element (105). A motor (102) is positioned within each opening (101a) to raise or lower the Braille dot element. The microcontroller unit (104) is configured to determine an input received from the interface (103) and selectively control the motor (102) to cause a rotary motion of the selected Braille dot element (105) based on the determined input.

Abstract: A media control device is provided. The media control device includes a first output port and a second output port. The media control device receives a user input indicative of disability information of a user. Further, the media control device controls the first output port to output a first audio portion of media content. The media control device further retrieves a second audio portion which describes a first image portion of the media content based on the received user input. The first image portion is associated with the first audio portion. The media control device further controls the second output port to output the first audio portion and the second audio portion based on the received user input.
