摘要： An optical element (200; 300) for providing a variable refractive surface. The element comprises a chamber (215) defined by at least one side wall (270), with an optical axis (90) extending through the chamber (215). The chamber (215) contains a first fluid (220) and a second fluid (230) in contact over a meniscus (225) extending transverse the optical axis (90). The perimeter of the meniscus (225) is constrained by said side wall (270). The fluids (220, 230) are substantially immiscible and have different indices of refraction. A first electrowetting electrode (242; 243) is arranged to act on at least a portion of the meniscus perimeter constrained by said side wall (270). A second electrowetting electrode (280) extends through the meniscus (225).

摘要： A device (100; 200; 300; 400) comprising a sealed cavity (210) containing n volumes of fluids (80, 87; 220, 230; 320, 332; 420, 422, 430, 432) is described, where n is an integer and n≧2. Each volume of fluid is substantially immiscible with every contiguous volume of fluid. The cavity is defined by an interior surface divided into n continuous areas (60, 170; 260, 270; 360, 362, 370; 460, 462, 470, 472), each continuous area corresponding to and being in contact with a respective one of the volumes of fluid. The wettability of each area is such that each volume of fluid preferentially adheres to the corresponding continuous area rather than any one of the continuous areas adjacent to the corresponding area.

摘要： A variable focus lens comprises a container enclosing an insulating liquid (A) and a conducting liquid (B), the insulating liquid (A) and the conducting liquid (B) being immiscible, having different refractive indices and being in contact with each other via an interface (14), the liquids (A, B) being at least partially placed in a light path through the container. The variable focus lens further comprises an electrode arrangement (2, 12) for controlling the shape of the interface (14) by means of an applied voltage. The container further comprises a transparent end portion (4) in the light path, a part (4) the transparent end portion (4) defining the shape of a part of the interface (14) at a predefined value of the voltage. Consequently, a variable focus lens with a reduced building height (H) is achieved that suffers less from the gradual formation of is small droplets of the conducting liquid (B) on the inner surface of the end portion (4).

摘要： The present invention discloses a method for measuring an intensity of a part of an electromagnetic spectral range, and an electronic device implementing the method. The method comprises the steps of providing an electronic device comprising an optical device (10) comprising at least a first liquid (A) and being placed in front of a sensor (120), the optical device (10) having a transmittance of the part of the electromagnetic spectral range depending on an orientation of at least the first liquid (A); measuring a first intensity of the electromagnetic (EM) spectral range; changing the orientation of at least the first liquid (A); measuring a second intensity of the electromagnetic spectral range; and calculating an intensity of the part of the electromagnetic spectral range from the difference between the first intensity and the second intensity. Consequently, an intensity for a part of the EM spectral range can be measured without the need for a sensor dedicated to this part of the EM spectral range. In particular, an optical element based on the electrowetting principle is used in a mobile phone to measure the intensity of UV radiation.

摘要： Motor, comprising a first body (3) and second body (5), the latter being movably mounted with respect to the first body. A chamber (4), sandwiched between surfaces of said bodies, is filled with a non-polar and/or non-conductive first fluid (6) and at least one volume of a polar and/or conductive second fluid (7), which fluids are immiscible. One of said surfaces is provided with means (10) for locally varying the wettability of said surface by the second fluid, to move the or each volume of second fluid along a desired path. The other surface is provided with means (9, 14, 15) for coupling the or each volume of second fluid to this surface, so that this surface will be dragged along by the moving volume or volumes. This results in a relative movement between both surfaces and hence in a movement of the second body.
