An ink stabilizing composition includes a polymeric network including an acrylate polymer and a plurality of high aspect ratio particles each having an aspect ratio of about 2:1 to about 30:1 and an average particle diameter of about 0.5 to about 1.2 micrometers.

Temperature-stabilization of convertible functional inks by disruption of conduction paths

A position tracking system includes a member extending along a lengthwise axis. Multiple position tracking elements (such as conductive strips) are fabricated to be exposed on a surface of the member. The multiple position tracking elements form a sequence along the lengthwise axis and are spaced apart from each other. The position tracking system further includes a probe. The probe monitors for presences and absence of the position tracking elements disposed in the sequence as the member and corresponding sequence of position tracking elements moves with respect to the probe. Based on the detected presence and absence of position tracking elements, a monitor resource of the position tracking system monitors parameters such as: i) a position of the member along the axis, ii) a rate of movement of the member along the axis over time, iii) a direction of movement of the member along the axis, etc.

Electronic position sensing system, method, and apparatus

A chip-embedded printed circuit board includes a cavity in a printed circuit board, a chip in the cavity of the printed circuit board, and a thixotropic dielectric filler in a gap in the cavity to seal the chip in the printed circuit board.

Nanocomposite material for ultraviolet curable direct write semiconductor applications

Among other concepts, this disclosure describes a thermal/optical/electronic authentication system (covert or non-covert) for device/system implementations. The authentication system may be based on different design parameters such as i) materials composition, ii) thickness of material, iii) geometry of material, iv) external effects including use of an external DC bias and curing, etc. The authentication testbeds can be configured to include one or more inks. Using such methods as discussed herein, the authentication can be broadened to include near-IR (700-900 nm), short wave IR (1-2.6 mm), and UVA (300-400 nm) or any spectrum. Printed resistors are very difficult to duplicate without Ag-BST13 ink. If necessary, a printed resistor network on a respective substrate can be hidden using a layer of non-sintered Ag-BST13 (non-conductive).

Multi-level authentication using different materials

A luminous system comprising one or more illumination sources, a multilayer structure, and one or more diffuse reflection layers being optically decoupled from the multilayer structure, wherein the emission and the reflection of the luminous system produce a first observed visible color when the one or more illumination sources are powered and a second observed visible color when the one or more illumination sources are non-powered is disclosed. Also disclosed are methods of creating the inventive luminous system.

Luminous systems

A chromic luminescent composition and method for fabricating the composition are disclosed. The chromic luminescent composition comprises at least one or more non-luminescent materials and one or more luminescent materials. The one or more non-luminescent materials having absorption spectra that at least partially overlap with the spectrum of incident electromagnetic radiation. The one or more luminescent materials convert at least a portion of energy of incident electromagnetic radiation to a lower energy wavelength. The one or more non-luminescent materials and the one or more luminescent materials are selected such that, when subsequently exposed to incident electromagnetic radiation, color and brightness are substantially modulated through absorption and emission as a function of incident electromagnetic radiation. Also disclosed are a chromic luminescent textile and a method for fabricating the textile.

An illuminator and a method for fabricating the illuminator are disclosed. The illuminator comprises at least a light source and a discriminator. The light source comprises one or more luminescent layers that substantially convert the energy of a primary electromagnetic radiation to an output radiation. The discriminator comprises one or more layers that substantially transmit the primary electromagnetic radiation to the one or more luminescent layers and reflect at least a portion of the output radiation from the one or more luminescent layers to the viewing hemisphere. A method for applying the illuminator to an object is also disclosed.

A luminescent end indicating tape comprising one or more base layers and an adhesive layer is disclosed. The one or more base layers provide support to the adhesive layer, whereas the adhesive layer comprises one or more fluorescent materials that convert at least a portion of incident electromagnetic radiation to a longer output wavelength. The adhesive layer redirects at least a portion of the longer output wavelength to at least an end of the tape, such that the end is illuminated with that of at least a portion of the longer output wavelength upon the tape being exposed to incident electromagnetic radiation. Further disclosed are methods of fabricating and using the luminescent end indicating tape.
