    摘要: A switchable element is described, which comprises a fluid chamber (111) containing a polar (101) and a non-polar (102) liquid, which are immiscible. The element is further provided with two electrodes (103,104), which are arranged to control the spatial distribution of the liquids, by means of an applied voltage across two the two electrodes. By the addition of surfactant to one or both of the liquids, the actuation voltage of the element is lowered. The element can work for example as an optical device or a motor.

    摘要: An electrowetting module (20) comprises a fluid chamber (8) which contains a first fluid (A) and a second fluid (B), which are separated by an interface (14) , and means (16, 17) to exert a force on at least one of the fluids to change the position and/or shape of the interface. By providing the second fluid body with a dissolved or mixed compound, being insoluble in or immiscible with the first fluid body, and/or the first fluid body comprises a dissolved or mixed compound being insoluble in or immiscible with the second fluid body, in amounts sufficient for lowering the freezing point of the respective fluids to below −20° C., the performance of the module can be improved so that the module can be used at low temperatures.

    摘要: An acoustic probe (100, 300) includes an acoustic transducer (15, 444), and a plurality of variably-refracting acoustic lens elements (10, 210a, 210b, 442) coupled to the acoustic transducer. Each variably-refracting acoustic lens element has at least a pair of electrodes (150, 160) adapted to adjust at least one characteristic of the variably-refracting acoustic lens element in response to a selected voltage applied across the electrodes. In one embodiment, each variably-refracting acoustic lens element includes a cavity, first and second fluid media (141, 142) disposed within the cavity, and the pair of electrodes. The speed of sound of an acoustic wave in the first fluid medium is different than the speed of sound of the acoustic wave in the second fluid medium. The first and second fluid media are immiscible with respect to each other, and the first fluid medium has a substantially different electrical conductivity than the second fluid medium.

    摘要: The disclosure is directed to a system for variably refracting, and is transparent for, ultrasound as well as for light. By choosing liquids with the right optical and acoustical properties, it is possible to variably refract (including focusing and deflecting or steering) ultrasound while not affecting the refraction of light, or vice versa. Two lenses in series, or preferably one lens, allow for variably refracting ultrasound and light.

    摘要: An imaging system with two modalities has a catheter with an optical lens system situated at an end of the catheter and optically connected to optical guide. The lens system has a numerical aperture which is changeable between a first aperture and a second larger numerical aperture. The imaging system also has an imaging unit for optical imaging with the catheter. First and second imaging modalities are optically connectable with the optical lens system of the catheter. The imaging system can change between imaging in two modes: (1) the first numerical aperture of the optical lens system and the first imaging modality of the imaging unit, and (2) the second numerical aperture of the optical lens system and the second imaging modality of the imaging unit.
