  • Patent number: 9494785
    Abstract: Image resolution enhancement techniques are implemented using a single image an unstructured broadband illumination. By placing an axicon and a convex lens pair in an optical path of a microscope, telescope, or the object system, between the system and an image capture pickup device (e.g., a camera) the maximum resolution of the system may be increased through the formation of an interference pattern at the image capture device.
    Type: Grant

  • Patent number: 9211539
    Abstract: A microfluidic arrangement including a fluid channel configured to receive a first fluid from a first inlet and a second fluid from a second inlet, and a mixer connected to the fluid channel, the mixer including a mixer channel configured to receive a volume of the first fluid and a volume of the second fluid from the fluid channel, the mixer channel defining a mixer capacity, wherein the mixer is (i) configured to mix the volume of the first fluid and the volume of the second fluid in order to provide a mixture of the first fluid and the second fluid when the combined volume of the first fluid and the second fluid is less than the mixer capacity, and (ii) further configured to mix the volume of the first fluid and the volume of the second fluid in order to provide a mixture of the first fluid and the second fluid when the combined volume of the first fluid and the second fluid is equal to the mixer capacity.

  • Patent number: 8753498
    Abstract: An open optoelectrowetting (o-OEW) device for liquid droplet manipulations. The o-OEW device is realized by coplanar electrodes and a photoconductor. The local switching effect for electrowetting resulting from illumination is based on the tunable impedance of the photoconductor. Dynamic virtual electrodes are created using projected images, leading to free planar movements of droplets.

  • Patent number: 8376317
    Abstract: A microfluidic purge valve in a microfluidics system includes a notch defined in the valve seat of a microfluidic valve. The notch is sized so that gas entrained within a liquid pumped through the microfluidics system can pass freely therethrough but the liquid cannot. The notch is sized so that the resistant force generated by the surface tension of the liquid is equal to or greater than the force generated by the fluid pressure.
