The multilayer stack reflects a single band of visible light with a hue between 0-40°, and preferably between 10-30°, on an a*b* Lab color map. The single band of visible light has a hue shift of less than 30° on the a*b* Lab color map when viewed from all angles between 0-45° normal to an outer surface of the multilayer stack. | 10-29-2015 |

| 20150316221 | Optical Film Stack for Light Duct - A film stack reflects incident light in some areas and transmits incident light in other areas, and it redirects incident light with one or more structured surfaces. The spatially variable reflection and transmission is achieved at least in part with reflective strips, and the reflective strips are attached to a first major surface of a structured optical film in the film stack. A second major surface of the structured optical film, opposite the first major surface, attaches to a substrate. The reflective strips attach to the structured optical film by a first discontinuous adhesive layer, having first adhesive areas. The structured optical film attaches to the substrate by a second discontinuous adhesive layer, having second adhesive areas. A major portion of the first adhesive areas, and a major portion of the second adhesive areas, is circumscribed by the reflective strips. The film stack may be part of a light duct. | 11-05-2015 |
| 20150318799 | ACTUATOR APPARATUS, ELECTRONIC DEVICE, AND CONTROL METHOD - An actuator apparatus includes a pair of substrates facing each other; a plurality of bias actuators that each vary a gap dimension of a gap between the pair of substrates; a gap detection portion that detects the gap dimension; and a voltage control unit that controls driving of each of the bias actuators on the basis of the detected gap dimension. The bias actuators are located asymmetric relative to a driving central axis and are mutually independently driven; and the voltage control unit derives driving parameters for use in driving the bias actuators, on the basis of voltages and gap dimensions obtained by sequentially switching and driving the bias actuators on by one. | 11-05-2015 |
