    Abstract: A security system is provided that integrates a unique set of structural features for concealing self-powered sensor and communication devices in aesthetically neutral, or camouflaged, packages that include energy harvesting systems that provide autonomous electrical power to sensors, data processing and wireless communication components in the portable, self-contained packages. Color-matched, image-matched and/or texture-matched optical layers are formed over energy harvesting components, including photovoltaic energy collecting components. Optical layers are tuned to scatter selectable wavelengths of electromagnetic energy back in an incident direction while allowing remaining wavelengths of electromagnetic energy to pass through the layers to the energy collecting components below. The layers uniquely implement optical light scattering techniques to make the layers appear opaque when observed from a light incident side, while allowing at least 50%, and as much as 80+%, of the energy impinging on the energy or incident side to pass through the layer.

    Abstract: A particularly-formed multi-layer micron-sized particle is provided that is substantially transparent, yet that exhibits selectable coloration based on its physical properties. The disclosed physical properties of the particle are controllably selectable refractive indices to provide an opaque-appearing energy transmissive material when pluralities of the particles are suspended in a substantially transparent matrix material. Multiply-layered (up to 30+ constituent layers) particles result in an overall particle diameter of less than 5 microns. The material suspensions render the particles deliverable as aspirated or aerosol compositions onto substrates to form layers that selectively scatter specific wavelengths of electromagnetic energy while allowing remaining wavelengths of the incident energy to pass. The disclosed particles and material compositions uniquely implement optical light scattering techniques in energy (or light) transmissive layers that appear selectively opaque, while allowing 80+% of the energy impinging on the light incident side to pass through the layers.

    Abstract: A method is provided that integrates an autonomous energy harvesting capacity in a mobile device in an aesthetically neutral manner. A unique set of structural features combine to implement a hidden energy harvesting system on a surface of the mobile device body structure or casing to provide electrical power to the mobile device, and/or to individually electrically-powered components in the mobile device. Color-matched, image-matched and/or texture-matched optical layers are formed over energy harvesting components, including photovoltaic energy collecting components. Optical layers are tuned to scatter selectable wavelengths of electromagnetic energy back in an incident direction while allowing remaining wavelengths of electromagnetic energy to pass through the layers to the energy collecting components below. The layers appear opaque when observed from a light incident side, while allowing at least 50%, and as much as 80+%, of the energy impinging on the energy or incident side to pass through the layer.
