Abstract: Synchronizing video content projected onto a transparent display with switching of pixels in the display. The transparent display has pixels capable of switching between a clear state to make portions of the display transparent and a hazy state to display the projected video. A decoder receives and decodes audio content associated with the video content in order to control the switching of the pixels in the display such that the video content is projected onto pixels in the hazy state.

Abstract: A display system includes a switchable display screen comprising a first transparent substrate, a first transparent conductive layer disposed upon the first transparent substrate, a second transparent substrate, and a second transparent conductive layer disposed upon the second transparent substrate. The display screen further includes a polymer-stabilized cholesteric texture layer and spacer elements disposed between and in contact with the first transparent conductive layer and the second conductive layer. The display screen comprises a plurality of addressable regions, each region capable of being switched from a transparent state to a diffuse state.

Abstract: A system for use in wirelessly monitoring a pipeline such as a natural gas pipe. The system includes a locator configured to wirelessly transmit power and a subsoil sensor marker located adjacent the pipe and configured to wirelessly communicate with the locator. The sensor marker includes a microcontroller, a memory module, a sensor configured to sense the presence of a gas, and a power module. The power module is configured to harvest a sufficient amount of the power wirelessly transmitted from the locator in order to operate the microcontroller to take a measurement via the sensor, save the measurement in the memory module, and wirelessly transmit the measurement to the locator.
