Abstract: A photodetector focal plane array (FPA) with enhanced detection capability and reduced thermal current is provided. The FPA includes light-concentrating dielectric structures in a form of arrays of elements with three-dimensional geometrical shapes. The elements have tapered sidewalls that taper inwardly toward a surface portion with a reduced width. A photodetector is joined to the portion with a reduced width. A metallic layer is disposed over the tapered sidewalls of the elements and the portion of the surface of the elements with a reduced width. The metallic layer provides mirror reflection properties to concentrate electromagnetic fields towards the detectors. The photodetector focal plane array may be used for infrared (IR) imaging applications in mid-wave IR (MWIR) and long-wave IR (LWIR) cameras as night vision and thermal imaging devices.

Abstract: The present disclosure relates to magnetization-free Faraday rotator systems, apparatuses, and related methods. One such system comprises a Faraday rotator device comprising a magneto-optical composite material having first and second magnetic component materials in a periodic or uniform pattern in an X-Y plane, wherein the first and second magnetic component materials are magnetized along a Z-axis in opposite directions and the Faraday rotator device produces nonzero magnetic Faraday rotation for the electromagnetic wave propagating in a Z-axis direction in the absence of an external bias magnetic field.

Abstract: The present invention provides liquid cleaning compositions useful in cold water and hard water laundry applications, and methods for making and using such compositions. The compositions of the invention use surfactants or surfactant blends, such as ?-sulfofatty acid esters or mixtures thereof (optionally along with one or more additional components), that have increased solubility/stability at cold temperatures, at higher-than-usual concentrations, and/or in hard water, with the composition remaining as a clear liquid. In certain embodiments, the compositions of the invention may be provided in the form of a unit dose, for example in a water-soluble pack or pouch. In use, the compositions of the invention result in an enhanced detergency along with a reduced amount of residue remaining in the machine, on laundered garments or cleaned dishware or hard surfaces, and on the body in personal care settings, and demonstrate a longer shelf-life, particularly when stored or used in colder temperatures.

Abstract: Embodiments of the invention provide a method for visually designating a plurality of points in three-dimensional space using an apparatus including at least one laser configured to emit visible light, at least one lens configured to collimate the visible light emitted from the laser, a plurality of independently controllable reflective surfaces wherein each surface is configured to independently steer a portion of the collimated visible light dynamically in time, and a control means configured to adjust the steering of the collimated light. The method includes selecting a plurality of points on an arbitrary plane. A portion of the collimated visible light is steered to locations corresponding to the selected plurality of points on the arbitrary plane. And, at least one of the points of the plurality of points is illuminated with the portion of the collimated visible light. Alternatively, a plurality of non-planar points is selected in the three-dimensional space.
