    摘要: Provided are an optical modulation device and a method of operating the same. The optical modulation device may include a nano-antenna, a conductor, and an active layer located between the nano-antenna and the conductor. The optical modulation device may further include a first dielectric layer located between the active layer and the conductor and a second dielectric layer located between the active layer and the nano-antenna. The optical modulation device may further include a signal applying unit configured to independently apply an electrical signal to at least two of the nano-antenna, the active layer, and the conductor.

    摘要: An IOL includes a fluid optic body having a cavity defined by a sidewall, a deformable optical membrane intersecting the sidewall around an anterior circumference of the sidewall, and a posterior optic intersecting the sidewall around a posterior circumference of the sidewall. The posterior optic includes a central protrusion extending anteriorly into the cavity and the deformable optical membrane includes a ring-shaped protrusion extending posteriorly into a space between the sidewall and the central protrusion. A second optic body is spaced apart from the fluid optic body and coupled thereto via a plurality of struts. Axial compression causes the plurality of struts to deform the sidewall in a manner that increases the diameter of the cavity, modifying a curvature of the deformable optical membrane is modified. Contact between the ring-shaped protrusion and the central protrusion defines a maximum modification to the curvature of the deformable optical membrane.

    摘要: Methods and apparatuses, including computer program products, are described for predicting the potential for severe weather. Data associated with lightning activity is received by a computing device. A location, a movement speed, a movement direction, and a lightning rate of one or more cells of lightning activity are determined by the computing device based on the received data. The lightning rate is compared, by the computing device, to a threshold lightning rate. One or more geographical areas at risk are determined by the computing device based on the location, the movement speed and the movement direction of the one or more cells of lightning activity. An alert is issued by the computing device to one or more remote devices monitoring the geographical areas when the lightning exceeds a value of the threshold lightning rate.
