  • Publication number: 20200101454
    Abstract: A micro-droplet-emulsifier to generate a micro-droplet-emulsion for application on digital polymerase chain reaction is provided. This device comprises of a micro-pipette to hold a dispersed-phase-liquid; a droplet generator that attaches to the micro-pipette and has a plurality of substantially flat micro-channels. The dispersed-phase-liquid is forced through the micro-channels to form micro-droplet-emulsion of dispersed-liquid-phase in the continuous-liquid-phase inside the chamber. The size of the micro-droplets is controlled by the shape and the aspect ratio of the micro-channels, the depth of micro-channel and the material of the micro-droplet-generator-head that dictates the contact angle of the droplet on the micro-channels.

  • Patent number: 10511759
    Abstract: An image capturing terminal includes a first camera module, a second camera module, and a processing module. The first camera module and the second camera module are used for framing concurrently a same scene and for detection and analysis according to contrast ratios of different frames of images, in which a focus search range includes a first focus area and a second focus area that do not overlap each other. The processing module is used for controlling the first camera module to search for a focus in the first focus area and, at the same time, for controlling the second camera module to search for a focus in the second focus area, and for capturing focus information of either the first camera module or the second camera module, and is used for controlling, according to the focus information, the first camera module to capture an image at the focus point.

  • Publication number: 20190318736
    Abstract: The embodiment of the disclosure provides a method for voice controlling, a terminal device, a cloud server and a system. The method includes: receiving voice information that the user performs voice controlling on a terminal device; transmitting voice information to the cloud server, so that the cloud server determines, according to the voice information, a voice control and a control instruction that match the voice information in the current interface, and generates a corresponding voice control instruction; receiving the voice control instruction transmitted by the cloud server; and controlling, according to the voice control instruction, a corresponding voice control of the terminal device to perform an operation. The method of the embodiments of the present disclosure achieves controlling over the controls in the interface through the voice, which deepens the controlling degree of the voice over the terminal device, and improves the user experience.

  • Publication number: 20190308326
    Abstract: Described are machine vision systems and methods for simultaneous kinematic and hand-eye calibration. A machine vision system includes a robot and a 3D sensor in communication with a control system. The control system is configured to move the robot to poses, and for each pose: capture a 3D image of calibration target features and robot joint angles. The control system is configured to obtain initial values for robot calibration parameters, and determine initial values for hand-eye calibration parameters based on the initial values for the robot calibration parameters, the 3D image, and joint angles. The control system is configured to determine final values for the hand-eye calibration parameters and robot calibration parameters by refining the hand-eye calibration parameters and robot calibration parameters to minimize a cost function.

  • Patent number: 9986148
    Abstract: Provided is an image capturing method and an image capturing terminal. The terminal includes a first camera module, a second camera module, and a processing module. The first camera module and the second camera module are used for framing concurrently a same scene. The resolution of an image outputted by the first camera module is greater than the resolution of an image outputted by the second camera module. The processing module detects and analyzes on the basis of the contrast ratios of different frames of images, and controls the second camera to automatically focus on a determined focus. The processing module also is used for determining a focus for the first camera module on the basis of focus information of the second camera module, controlling the first camera module to focus directly on the basis of the determined focus and to capture an image while focused on the focus.
