  • Publication number: 20210333533
    Abstract: A method and system for autofocusing an objective lens in a microscope system are disclosed. A decentered aperture is disposed in an optical path between an objective lens and an image plane of an image capturing device and a plurality of reference images are captured. Each reference image is captured when the objective lens is positioned at a corresponding z-position of a plurality of z-positions along an axis of travel of the objective lens and the optical path is at least partially occluded by the decentered aperture. At least one reference image of the plurality of the reference images is associated with a best focus position. The plurality of reference images are analyzed to develop a plurality of pattern locations, wherein each pattern location represents a position of a pattern formed on the image plane when a corresponding reference image was captured. The objective lens is positioned in accordance with the best focus position and the plurality of pattern locations.

  • Patent number: 11086118
    Abstract: Systems and methods for autofocusing an objective lens in a microscope system. A self-calibrating autofocus system includes a light source, a decentered aperture, and image-capturing device. The system may be connected to the microscope system so that the light source generates a light on an optical path that includes the objective lens and a plate having a reference surface proximal to a sample holding component. The image capturing device images a reflection of light from the reference surface as the objective lens moves to a series of z-positions. A reference calibration slope is generated for the objective lens by determining positions of the images taken at the z-positions of the objective lens. At least one image having a particular attribute corresponds to a best focus position. The objective lens is moved to predicted best focus or preferred offset from calibrated best focus using the reference calibration slope.

  • Publication number: 20210233363
    Abstract: A gaming machine comprising a display, and a game controller that at least: selects a first set of symbols, causes the display to display the first set of symbols at a first set of display positions and conducts a random selection process so that a second set of display positions has an overlapping spatial relationship with a first set of display positions. The random selection process includes a first type of outcome where a designated number of special symbols is selected and a second type of outcome where less than the designated number of special symbols is selected. Upon the occurrence of the second type of outcome, the game controller displays the less than the designated number of special symbols selected at either individual ones of the first set of display positions or of the second set of display positions, and triggers a feature game for conducting feature game play.

  • Publication number: 20210209898
    Abstract: An electronic gaming machine includes a processor configured to control a display device to display a plurality of columns of symbol positions, where each symbol position includes a symbol selected from a set of symbols. The processor is also configured to determine whether any of the symbol positions include a designated symbol, and if so, to: i) control the display device to hold the designated symbol in the symbol position for at least one subsequent game instance of a series of game instances, and ii) increase a multiplier used in determining a game award from a first multiplier to a second, larger, multiplier. The processor is also configured to evaluate the symbols included in each symbol position to determine whether a winning combination of symbols is displayed. If a winning combination of symbols is displayed, the processor also calculates a game award using one of the first multiplier or the second multiplier.

  • Patent number: 10983325
    Abstract: Method and system for trans-illumination imaging. In an exemplary method, a sample is irradiated in a well. The sample may include biological cells and a liquid or semi-solid medium that forms a meniscus. The step of irradiating may be performed with an array of light sources generating light of respective light beams that are incident on the meniscus at different orientations from one another. One or more images may be detected. A proportional contribution of light from two or more subsets of the light sources to the one or more images may be controlled by differential energization of the two or more subsets relative to one another to compensate for refraction by the meniscus and improve contrast.

  • Publication number: 20210049869
    Abstract: An electronic gaming system includes at least one processor configured to provide a reel-based wagering game. In the game, a matrix of symbol positions is displayed, and during each spin of the reels, the processor determines whether at least one symbol displayed in the matrix is a target (or collectable) symbol. When at least one target symbol is displayed, the processor also determines whether a threshold number of such target symbols have been accumulated from the matrix by the player, and if so, the processor awards a plurality of free games, each of which is evaluated against an upgraded paytable. The upgraded paytable defines a plurality of upgraded awards for a variety of symbol combinations, at least some of which incorporate the target symbol. In some cases, a different (e.g., upgraded) version of the target symbol may be displayed during free games.
