Abstract: Emulsion breaking and phase separation is achieved by droplet adhesion. An emulsion breaking device includes a channel having distinct adjacent zones with distinctly different surface wettability characteristics, namely, solvophilic and solvophobic surfaces. The device is positioned such that the upstream portion of the device is configured to be wetted by the continuous phase of the emulsion, and the downstream portion of the device is configured to be wetted by the dispersed phase of the emulsion. As the emulsion flows from the upstream zone to the downstream zone, the change in surface wettability characteristics promotes adhesion of the dispersed phase as the dispersed phase wets the surface of the downstream portion of the channel, which results in breaking of the emulsion. Subsequent collection of the broken emulsion in a collection vessel results in separation of the disparate phases to facilitate their recapture and recycling.

Abstract: A reference plane generating unit generates a reference plane of light parallel to a display surface. For example, the reference plane generating unit projects a plane of infrared light parallel to a plane including the display surface. When a pointer, such a stylus or a finger, breaks the reference plane, light is reflected from the reference plane, with at least a portion of the reflected light directed toward an image capturing unit. Based on the reflected light captured by the image capturing unit, the image processing unit determines a position of the pointer in the reference plane and determines a touch signal corresponding to the determined position of the pointer. The touch signal is communicated to a processing unit, such as a mobile device, that performs an operation corresponding to the determined touch signal.
