Patent number: 9904070Abstract: An electromagnetic driving device is provided, which includes a stationary portion, a movable portion adapted to support an element, a number of rolling balls, a driving magnet, a driving coil, and a magnetic attraction element. The stationary portion and the movable portion are arranged along a main axis. The rolling balls and the driving magnet are positioned between the stationary portion and the movable portion. The driving coil is arranged to correspond to the driving magnet and configured to enable the movement of the movable portion along a direction perpendicular to the main axis. The magnetic attraction element is arranged to correspond to the driving magnet. The magnetic force between the magnetic attraction element and the driving magnet is greater than the sum of the weight of the movable portion, the element, and the magnetic member.Type: GrantFiled: May 2, 2016Date of Patent: February 27, 2018Assignee: TDK TAIWAN CORP.Inventors: Chao-Chang Hu, Shu-Shan Chen, Chih-Wei Weng

Patent number: 9906707Abstract: A method of adjusting a lens may include adjusting the lens at a first focus position, and acquiring a first image of a scene through the lens. The method may further include adjusting the lens at a second focus position, and acquiring a second image of the same scene through the lens. In addition, the method may include producing respective power spectra of the first and second images, and producing a criterion representing the ratio of the power spectra to estimate a focus error of the lens.Type: GrantFiled: August 24, 2015Date of Patent: February 27, 2018Assignee: STMICROELECTRONICS (GRENOBLE 2) SASInventors: Jérémie Teyssier, Francesco Cascio

Patent number: 9905041Abstract: Techniques are disclosed for synthesizing depth of field effects in a digital image using ray tracing approximation. For each target pixel in the image, an aperture-shaped kernel is centered about a reference pixel. A cone of rays is traced through the aperture toward the image scene. The trajectory of the rays and the intersections between the rays and objects in the scene are approximated for a given scene depth, focal depth and aperture shape. The color of the pixel lying at the intersection, which may be offset from the target pixel, is sampled. This sampling process is repeated for several apertures bounding the target pixel, where each aperture is centered about a different reference pixel. The resulting color of the target pixel is acquired by integrating the colors of the pixels at each of the resulting intersections.Type: GrantFiled: November 24, 2014Date of Patent: February 27, 2018Assignee: Adobe Systems IncorporatedInventor: Zhan Yu

Patent number: 9864296Abstract: An optical scanner includes a light source including a plurality of light emitting elements, a polygon mirror which deflects light from the light source for scanning a surface of a subject, an optical element arranged between the light source and the polygon mirror, having optical power in a sub scanning direction, a synchronous detector which detects the light deflected by the polygon mirror for synchronous detection and generates a signal for controlling a timing at which the scanning of the surface is started, and a fixing element which secures one end of the optical element. The light emitting elements of the light source are aligned with a certain tilt angle relative to the sub scanning direction. Light from one of the light emitting elements disposed closest to the fixing element in a main scanning direction is used for synchronous detection.Type: GrantFiled: March 10, 2015Date of Patent: January 9, 2018Assignee: RICOH COMPANY, LTD.Inventors: Tomoya Fujii, Tadashi Nakamura, Nobuyuki Arai, Yoshinobu Sakaue, Noboru Kusunose, Daisuke Imaki

Patent number: 9851550Abstract: Microscope slide scanner. In an embodiment the microscope slide scanner comprises a single enclosure unit that includes at least one objective lens, at least one line scan camera, at least one communication port, and at least one processor. The line scan camera may be configured to capture image data of a sample as a plurality of image stripes via the objective lens. The communication port provides communication over a network. The processor may align the plurality of image stripes into a contiguous image of at least a portion of the sample, and executes a web server that provides an operator interface over the network to one or more remote devices.Type: GrantFiled: July 1, 2016Date of Patent: December 26, 2017Assignee: LEICA BIOSYSTEMS IMAGING, INC.Inventor: Dirk G.

Patent number: 9853740Abstract: Adaptive communications focal plane arrays that may be implemented in, e.g., a specially-configured camera that can be utilized to receive and/or process information in the form of optical beams are presented. A specialized focal plane array (FPA) having a plurality of optical detectors is utilized, where one or more optical detectors are suppressed such that data is not allowed to be output from the one or more suppressed optical detectors, and only a significantly smaller number or subset of optical detectors receiving optical beams are allowed to output data. In this way, the rate at which data is to be output by an adaptive communications FPA (ACFPA) can be significantly reduced.Type: GrantFiled: June 6, 2017Date of Patent: December 26, 2017Assignee: SUREFIRE LLCInventors: John C.
