  • Publication number: 20190191503
    Abstract: An electronic apparatus and a light-emitting module driving circuit thereof are provided. The electronic apparatus includes a light-emitting module and a driving circuit. The driving circuit is coupled to the light-emitting module and is configured to generate a driving signal set to drive the light-emitting module. The driving circuit includes a first driver, a second driver, and a switching circuit. The first driver receives a control signal related to an operation status of the electronic apparatus and generates a first signal set according to the control signal. The second driver includes at least one resistor which receives system power and accordingly generates a second signal set. The switching circuit is coupled to the first driver and the second driver to receive the first signal set and the second signal set, respectively. When the switching circuit does not receive the first signal set, the switching circuit takes the second signal set as the driving signal set.

  • Patent number: 10277790
    Abstract: A full-range image detecting system including a planar light source, an image capturing device, a light sensing device, a processing unit and a measuring module is provided. The planar light source projects a photo image with periodical variations onto an object. The image capturing device captures a reflective photo image reflected from the object. The light sensing device detects the coordinates of at least three measuring points on the object for fitting a plane. The processing unit calculates a phase variation of the reflective photo image after phase shift, a relative altitude of the surface profile of the object according to the phase variation, and an absolute altitude of the surface profile of the object with respect to the plane to obtain an information of absolute coordinate. The measuring module detects the surface of the object according to the information of absolute coordinate of the object.

  • Publication number: 20190012430
    Abstract: A method of creating characteristic peak profiles of mass spectra and identification model for analyzing and identifying microorganisms are provided. MALDI-TOF MS data of microorganisms having the same feature are gathered. Discretization of the data is performed. Density-based clustering is used to find m/z values of spectral peaks with high probability of occurrence from the discretized data. A characteristic MS peak profile is created for every specific feature of microorganisms. Every such a characteristic profile forms a feature template. The mass spectrum of each known isolate is matched against all the feature templates and a number of matched vectors are obtained. The matched vectors are then concatenated into a single “integrated vector.” Then, a machine learning method and the integrated vectors generated from all known isolates are used to create a classification model for microorganism identification.

  • Publication number: 20180120078
    Abstract: A flatness measurement device includes a movement platform, a standard component, a first flatness measuring device, a second flatness measuring device and a processor. The movement platform is used for driving a to-be-measured object to move. The standard component and the movement platform move together. The first flatness measuring device is used for measuring a first flatness information of the to-be-measured object when the to-be-measured object moves. The second flatness measuring device is used for measuring a second flatness information of the standard component when the standard component moves. A flatness information of the to-be-measured object is obtained by deducting the second flatness information from the first flatness information by the processor.
