  • Patent number: 9229218
    Abstract: Microstructured hybrid actuator assemblies in which microactuators carrying designed surface properties to be revealed upon actuation are embedded in a layer of responsive materials. The microactuators in a microactuator array reversibly change their configuration in response to a change in the environment without requiring an external power source to switch their optical properties.

  • Patent number: 9217851
    Abstract: A zoom lens includes a front unit including one lens unit having a negative refractive power, and a rear unit including an aperture stop and one or more lens units and having a positive refractive power as a whole, and an interval between adjacent lens units changes during zooming such that an interval between the front unit and rear unit decreases at a telephoto end when compared to a wide angle end. The front unit includes a negative lens G11 in a position closest to the object side, and a lens surface of the negative lens G11 on the image side has an aspherical shape by which the positive refractive power increases from a center to an edge. Various parameters for the zoom lens according to the present invention are properly set.

  • Patent number: 9207456
    Abstract: In a virtual image display device, since the frame section has the support section for detachably fixing the auxiliary mounting member, which is disposed adjacent to the optical members, on the observer side of the optical members, by providing a variety of functions such as an optical function to the auxiliary mounting member, the usefulness of the virtual image display device can be enhanced. Specifically, in the case of, for example, providing the auxiliary mounting member with a diopter correction function, it is possible for any observers with a variety of levels of vision to observe the image obtained by the video display element in a good condition without blur without using eyeglasses.

  • Patent number: 9195111
    Abstract: An electro-optic medium comprises at least one leuco dye such that the electro-optic medium can develop at least two differing colors upon exposure to two or more differing stimuli. The medium allows for development of differing colors in differing areas of the medium, thus allowing formation of intrinsic color within differing areas of a single layer of the same electro-optic medium. In an electrophoretic medium, the colors may be developed within the electrophoretic particles or within the fluid in which the particles are dispersed.
