  • Patent number: 8662634
    Abstract: An image forming apparatus includes a liquid ejection head, a head tank, a liquid storage container, a liquid supply passage, a liquid feed device, a control valve, and a suction device. The control valve is disposed at the liquid supply passage to open and close the liquid supply passage between the head tank and the liquid storage container. The head tank has a filter, a flow channel, a deformable wall face member, and a gap maintaining elastic member. The wall face member is opposed to the filter and forms a wall face of the channel. The elastic member is disposed in the head tank to urge the wall face member in a direction to increase a gap between the wall face member and the filter. When the suction device sucks liquid from the nozzles with the valve closed, the wall face member deforms in a direction to approach the filter.

The image is correlated with the plurality of comparison objects to yield a local best match between the image and the comparison objects when there is a coincidence of one of the ring-shaped comparison objects and a ring-shaped jump in brightness in the image having the same radius and the same center. The comparison objects having a local best match with the image are determined. Thereafter, the position of the center of the comparison object having a local best match with the image is selected as the position of the center of the limbus and/or the position of the center of the pupil.

    Abstract: An ophthalmic illuminator includes a one or more light combining stages arranged in series to augment a white light source with various color spectral bands. A first stage combines white light from a white light source with colored light from a first color source. Each subsequent stage in the series adds its own respective colored light. The color sources may be selectively turned on/off or driven with variable amounts of power. In this fashion, a combined light is produced by the final stage that represents a desired chromaticity and brightness as desired for a particular ophthalmic therapeutic procedure.

  • Patent number: 8662671
    Abstract: The present invention features an optical apparatus for the transmission of a virtual image to facilitate an individual's copy or reproduction thereof onto a working surface. The optical apparatus provides an image transfer that is more realistic than apparatuses of the prior art because of the illusion that the image is in actual contact with the working surface, when in reality the image impinges only a transparent medium. In addition, the invention provides a more effective image transfer than conventional devices by not including an opaque transfer of the artist's hand and/or art utensil, but rather by rendering the illusion that the artist's hand and/or art utensil is transparent. The optical apparatus consists of a supporting frame upon which is mounted a light source, an upper transparent support plate, a lower plate consisting of at least two layers, and a working surface on which is disposed canvas or paper for receiving the artist's final, copied image or work.

  • Patent number: 8662676
    Abstract: Devices and techniques are described for automatically calibrating a projector system. The projector system undergoing calibration is coupled to a computing device and an automated positioning platform coupled to a target structure. The computing device acquires images using a calibrated camera of one or more patterns projected by the projector onto the target structure when the target structure is in a plurality of repeatable poses. From these acquired images, intrinsic projector parameters may be determined. Once determined, the parameters may be used to correct images produced by the projector or acquired by the camera which include a projected pattern or portion thereof.

  • Patent number: 8662677
    Abstract: A projection apparatus, an illumination module and a brightness adjusting method for the projection apparatus are provided. The projection apparatus comprises the illumination module and the actuator. The illumination module comprises a luminous element. First, the actuator drives the luminous element to move from the first position to the second position to detect the first brightness and second brightness generated by the luminous element. When the first brightness is higher than the second brightness, the actuator is adapted to drive the luminous element to the first position. Thereby, the brightness of a projection image generated by the projection apparatus can be adjusted to an optimal value.

  • Patent number: 8662679
    Abstract: An object-side lens group has different power factors between the vertical and horizontal directions of a liquid crystal panel, and a projection system as a whole therefore has different focal lengths between the vertical and horizontal directions and hence different magnification factors between the vertical and horizontal directions, whereby the aspect ratio of an image on the liquid crystal panel can be set at a value different from the aspect ratio of an image projected on a screen. That is, the projection system can convert the aspect ratio, which is the ratio of the width to the height of an image. When the distance between a diaphragm and an extreme end surface of the object-side lens group on the screen side satisfies a predetermined condition, at least a certain degree of telecentricity can be provided both in the vertical and horizontal directions.
