  • Patent number: 10254619
    Abstract: The present invention provides driving methods for electrophoretic color display devices. The backplane system used for the driving methods is found to be simpler which renders color display devices more cost effective. More specifically, the driving method comprises first driving all pixels towards a color state by modulating only the common electrode, followed by driving all pixels towards their desired color states by maintaining the common electrode grounded and applying different voltages to the pixel electrodes.

  • Patent number: 10194797
    Abstract: A method for selecting an intraocular lens (IOL) to be implanted into an eye, in which the selection is based on a non-paraxial approach. In a ray tracing method for selecting an intraocular lens to be implanted into an eye with a simplified, centered optical system, in addition to the preoperatively measured biometric values, the effective lens position of the corresponding eye and the optical transfer function of the IOLs are used, which are calculated for a standardized distance behind the equatorial plane of the IOL. The method may be used to select an intraocular lens to be implanted into an eye and is equally suitable for spherical, aspherical, toric and multifocal IOLs.

  • Patent number: 10191189
    Abstract: A wide angle optical lens, an optical lens unit, and an imaging device are small-sized and can secure an attachment space even when space is limited, and can avoid adhesion peeling or the extrusion of an adhesive. Optical lens (10) has a lens frame receiving surface (2a) on the side of first optical surface (S1) having a smaller optical surface diameter than second optical surface (S2), and is further provided with an adhesion space forming surface (3a) on the surrounding side of the lens frame receiving surface (2a). Therefore, it is possible to suppress adhesion peeling even when a smaller size is requested. Furthermore, by securing a larger size for lens frame receiving surface (2a), it is possible to suppress leakage or extrusion of adhesive from lens frame receiving surface (2a) and thus adherence to first optical surface (S1).

The projection direction corresponds to a center of the image. The diffusion portion diffuses the light from the light source. A distance between the first optical surface and the second optical surface increases in a direction from a side on which the diffusion portion is closer to the light source portion to a side on which the diffusion portion is farther from the light source portion.

  • Patent number: 10175470
    Abstract: The disclosed examples relate to methods and systems facilitate self-healing of regions of electrowetting devices. Electrowetting devices may be coupled to a switchable AC/DC electrical power supply that provides AC power to the electrowetting device to control electrowetting device operation and DC power to promote self-healing of the electrowetting device. A monitoring circuit outputs a signal in response to electrical power supply operating characteristic changes due to a failure of the electrowetting device's dielectric. The controller, responding to the signal, switches the power supply output from AC power to DC power to the electrowetting device. In response to the DC power, the electrowetting device responds by healing the degraded dielectric. When the failure is determined to be corrected, the power supply output is switched from DC power to AC power to the electrowetting device. The number of times self-healing is applied may be tracked for future analysis.
