  • Patent number: 10386655
    Abstract: Techniques and mechanisms for sensing an overlap of an ophthalmic device by an eyelid of a user while the ophthalmic device is disposed in or on an eye of the user. In an embodiment, a circuit, disposed in a sealed enclosure of the ophthalmic device, interacts via an electromagnetic field with a film of tear fluid that is formed on the ophthalmic device. Based on the electromagnetic interaction, an oscillation characteristic of the circuit is evaluated. The oscillation characteristic varies with a resistance that is due in part to an eyelid of the user overlapping at least some portion of the ophthalmic device. Based on the evaluated oscillation characteristic, an amount of the eyelid overlap is determined by circuitry of the ophthalmic device. In another embodiment, the amount of eyelid overlap is used to determine one or more characteristics of gazing by the user's eye.

  • Patent number: 9001282
    Abstract: A variable power optical element is divided into cells which contain two liquid crystals mixed according to different proportions. The proportion of one of the liquid crystals in each cell increases on the basis of the radial distance between a central point of the optical element and said cell. An appropriate selection of the two liquid crystals results in a higher variation of the optical power between two control states of said optical element. More particularly, the optical element may consist of an ophthalmic lens which changes between a convergent lens state and a divergent lens state.

    Abstract: According to one embodiment, an apparatus includes first and second liquid crystal lenses, a pair of temples, a sensor, and a driver. The first liquid crystal lens includes a first liquid crystal layer and a plurality of first control electrodes on the first liquid crystal layer. The sensor is provided on one of the pair of temples, and detects a contact position on a detector plane. The driver applies a plurality of voltage to the plurality of the first control electrodes. A focal length of the first liquid crystal lens is determined according to an amount of movement of the contact position when the contact position continuously moves along a longitudinal direction of the sensor. Each voltage value is determined according to the focal length of the first liquid crystal lens.

  • Patent number: 8994797
    Abstract: A display system comprises a display device for accomplishing 3D displays by displaying images for the left eye and images for the right eye, and a display assistance device for separating them for viewing, and the display assistance device detects the wearing status and inclination of the viewer and sends status information to the display device. The display device determines whether or not the posture of the viewer is within a normal viewing range on the basis of the status information, and if this is within the range, can recognize a 3D display even in a posture other than the horizontal direction by controlling the parallax direction of the display of images in accordance with the inclination direction. When the posture is outside the range, the display device prompts correction of the posture or weakens the effect of the 3D display.

  • Patent number: 8988648
    Abstract: Techniques are disclosed for creating optical systems and devices that provide through-sight information while enabling the optical systems and devices to maintain a small, lightweight form factor. According to certain embodiments of the invention, an optical assembly can include a liquid-crystal display (LCD) disposed between the two prism elements of a Schmidt-Pechan prism at a focal plane of the optical assembly. This allows the LCD to be used to display information by blocking light passing through the optical assembly. Additionally, a light-emitting display, such as a backlit LCD, light-emitting diode (LED) display, or organic LED (OLED) display, can be coupled at a surface of one of the two prism elements of the Schmidt-Pechan prism to provide additional information in low-light environments.
