Abstract: An asset tracking system includes a tracking device associated with a mobile asset and a centralized device management platform. The tracking device is configured via a set of device configurations. The centralized device management platform includes one or more processors in communication with the tracking device and computer-readable memory encoded with instructions that, when executed, cause the system to receive location data corresponding to a location of the tracking device; evaluate the location data to identify a zone corresponding to a physical region that includes the location of the tracking device; compare an identified zone with a set of location-based rules to identify a rule associated with the identified zone; update the set of device configurations with a device configuration that is associated with an identified rule; and sync an updated set of device configurations to the tracking device to reconfigure the tracking device based on the identified rule.

Abstract: While gold wire grids have been used to polarize infrared wavelengths for over a hundred years, they are not appropriate for shorter wavelengths due to their large period. With embodiments of the present invention, grids with periods a few tens of nanometers can be fabricated. Among other things, such grids can be used to polarize visible and even ultraviolet light. As a result, such wire grid polarizers have a wide variety of applications and uses, such as, e.g., in the fabrication of semiconductors, nanolithography, and more.

Abstract: A system and method of replacing a lens to treat a cataract is disclosed. Cataractous tissue is ablated via a multi-photon process using focused, ultra-short laser pulses. Multi-photon ablation requires an energy intensity between 1013 to 1015 W/cm2. Using lasers having femto-second duration pulses, this intensity is achieved with 50 micro-Joules of energy, allowing material disruption with very little heating or shock. The multi-photon ablated material is removed through a micro-channel that leads from the multi-photon ablated region to at least the surface of the eye. Once the material is removed a pre-polymer fluid is injected in to fill the void. This polymerizes into a gel once inside the lens. The polymerized, transformed material matches both the transparency to visible light and the Young's modulus of healthy lens.

Abstract: The invention relates to devices, compositions and methods used to improve vision and/or to treat an eye lens disease or condition. In some embodiments, the invention relates to altering or removing eye lens material for the treatment of presbyopia. In additional embodiments, the invention relates to placing compositions in a lens of an eye to improve elasticity of the lens both therapeutically by improving elasticity and/or improving refractive properties and/or prophylactically by preventing renewed stiffening and/or renewed deterioration of the lens refractive properties. In further embodiments, the invention relates to devices and methods of obtaining and analyzing data for use in altering the lens to optimize its elasticity and/or refractive properties.

Abstract: A method and apparatus is disclosed for providing shear-induced alignment of nanostructures, such as spherical nanodomains, self-assembled nanodomains, and particles, in thin films, such as block copolymer (BCP) thin films. A silicon substrate is provided, and a thin film is formed on the substrate. A pad is then applied to the thin film, and optionally, a weight can be positioned on the pad. Optionally, a thin fluid layer can be formed between the pad and the thin film to transmit shear stress to the thin film. The thin film is annealed and the pad slid in a lateral direction with respect to the substrate to impart a shear stress to the thin film during annealing. The shear stress aligns the nanostructures in the thin film. After annealing and application of the shear stress, the pad is removed, and the nanostructures are uniformly aligned.

Abstract: Methods of nanometer pattern formation and transfer onto a selected substrate are provided wherein a selected block copolymer is coated onto the selected substrate and a component of the block copolymer is chemically modified or physically removed so that the dense periodic pattern of the block copolymer can be transferred onto the selected substrate. Substrates prepared by these methods are also provided.
