摘要:
An X-ray imaging apparatus includes a top transparent conductive layer and a bottom transparent conductive layer electrically connected to the top transparent conductive layer. The apparatus also includes an X-ray field modulator positioned adjacent to the bottom transparent conductive layer and an electro-optic layer positioned between the X-ray field modulator and the top transparent conductive layer. The X-ray field modulator is configured to modulate one of a resistance and a charge level therethrough when exposed to different X-ray levels to thereby create different levels of voltage drop across the electro-optic layer. In addition, the different levels of voltage drop causes varying optical properties to appear in the electro-optic layer.

摘要:
Provided is a low cost system and method for forming electronic devices, especially large surface area devices. The process of imprint lithography is combined with alternate manufacturing techniques to fabricate the devices. Initially, a template imprints a three-dimensional pattern into a resist layer deposited on a flexible substrate. The resist layer is cured using ultraviolet light or other curing techniques. After curing, the 3-D pattern is modified using one of several techniques to include inkjetting, electrodeposition or laser patterning. In one embodiment, a semi-fluid material may be jetted into channels formed in the pattern, thereby forming conductive or insulating lead lines. Alternatively, a two-dimensional pattern may be jetted onto the resist layer. Final processing may include multiple etch-mask-etch steps. The integration of techniques into a single system provides a low cost, efficient method for manufacturing high quality, large surface area electronic devices.

Disclosed is an anti-counterfeiting system. In a particular embodiment, the anti-counterfeiting system has a first structure having a plurality of three-dimensional nanostructures, each having a height dimension less than a wavelength of visible light. In addition, there is a second structure having a second plurality of three-dimensional nanostructures, each having a height dimension less than a wavelength of visible light. The first and second structures are configured to couple together. An alignment mechanism is operable to align the first structure to the second structure and establish proximate contact between the first and second pluralities of nanostructures. With respect to the first and second structures, each encodes part of an authentication key. The authentication key includes pre-determined elements and interaction modalities. The resolution of the structures makes them copy-resistant. An associated method of use is also provided.

A tactile display for providing tactile feedback has a touch surface layer formed of a plurality of pixels. Each pixel has an aperture for ejecting a fluid, and a valve for opening and closing the aperture. The valve is operable to modulate the fluid ejection through the aperture at a frequency selected for detection by the somatic sensors of a human finger.
