Patent number: 11291992Abstract: A portable and completely self-contained apparatus(20) for detecting analyte and the methods of use thereof is described. The apparatus (20) includes a microfluidic cartridge driver unit (30), an optical inspection unit (32), and a control unit (28) and a power supply unit, which can run the binding and detection of the analyte without any fluidic interfaces to the instrument. The microfluidic cartridge driver unit (30) receives microfluidic cartridge (22) that holds a microarray and integrated microfluidic chip (24) for delivering the analyte to perform different process steps in the detection of analyte. A complete detection of analyte using the invention takes only a few minutes.Type: GrantFiled: August 5, 2015Date of Patent: April 5, 2022Assignee: Sanwa BioTech LtdInventors: Isabelle Cécile Angèle Dutry, Kin Sun Ip, Kelvin Chiu, Wai Lam William Yim, Yiu Ting Richard Lau

Patent number: 10666920Abstract: A method of altering audio output from an electronic device based on image data is provided. In one embodiment, the method includes acquiring image data and determining one or more characteristics of the image data. Such characteristics may include sharpness, brightness, motion, magnification, zoom setting, and so forth, as well as variation in any of the preceding characteristics. The method may also include producing audio output, wherein at least one characteristic of the audio output is determined based on one or more of the image data characteristics. Various audio output characteristics that may be varied based on the video data characteristics may include, for instance, pitch, reverberation, tempo, volume, filter frequency response, added sound effects, or the like. Additional methods, devices, and manufactures are also disclosed.Type: GrantFiled: February 27, 2018Date of Patent: May 26, 2020Assignee: Apple Inc.Inventors: Aram Lindahl, Kelvin Chiu

Patent number: 9466127Abstract: Various techniques relating to the alteration of image data are provided herein. An electronic device capable of carrying out such techniques may include data processing circuitry configured to receive image data and detect the occurrence of a device operation event (e.g., an audio event, a motion event, a location event, or an image event, and so forth). The data processing circuitry may alter the image data using a full-quality version or a reduced-quality version of an image alteration effect associated with the device operation event, depending on currently available resources.Type: GrantFiled: September 30, 2010Date of Patent: October 11, 2016Assignee: Apple Inc.Inventors: Aram Lindahl, Kelvin Chiu

Patent number: 8933960Abstract: Various techniques relating to the alteration of image data are provided herein. In generally, disclosed embodiments may provide techniques for applying on or more image alteration effects to image data that is displayed on an electronic device. In certain disclosed embodiments, the application of such image alteration effects may be triggered based upon various detected device operation events, which may include audio-related events, motion-related events, location-related events, and/or events relating the imaging properties. The selection of a triggering device event and a corresponding image alteration affect may be defined by a user through a set of user preference settings on the electronic device.Type: GrantFiled: August 14, 2009Date of Patent: January 13, 2015Assignee: Apple Inc.Inventors: Aram Lindahl, Kelvin Chiu
