  • Publication number: 20220360685
    Abstract: An image outputting device includes a scanning module, a storage module, an identification module, a calibration module and a printing module. The scanning module generates an image by scanning an object. The storage module stores the image. The identification module identifies a layout orientation and a text orientation of the image. The calibration module calibrates the layout orientation and the text orientation of the image according to a relation of an identification result of the identification module and a layout orientation of the printing medium. When the printing module prints the calibrated image on a printing surface of the printing medium and outputs the printing medium with the printing surface facing downwardly, the layout orientation of the printed image matches with the layout orientation of the printing medium, and the text orientation of the printed image is opposite to an medium outputting direction or arranged from proximal to distal.

    Abstract: A projection type transparent display includes a polarization modulator and a reflective layer. The polarization modulator is stacked in sequence by a linear polarizer, a liquid crystal layer and a phase retarder. The reflective layer is stacked on the phase retarder. A projection light is incident on the linear polarizer to form a linearly polarized light. The liquid crystal layer changes a polarization direction of the linearly polarized light. Two kinds of linearly polarized projection lights with polarization directions orthogonal to each other are respectively formed and pass through the phase retarder to respectively form two kinds of circularly polarized projection lights with opposite rotation directions.

  • Patent number: 11480450
    Abstract: An EHz ultrafast modulated pulse scanning laser and a distributed fiber sensing system. A plurality of phase-shift gratings are engraved on a doped fiber, the phase-shift gratings having different central window wavelengths and a wavelength interval between the adjacent central window wavelengths being a preset fixed value. When a pump light emitted by a pump laser source is coupled by a wavelength division multiplexer and enters the doped fiber, a single-mode narrow-linewidth laser light having multiple wavelengths with a wavelength interval being a preset fixed value can be generated, by using the phase-shift gratings graved on the doped fiber. The ultrafast modulation is completed by using a time-domain control method based on an EOM. An internally frequency converted pulse light formed by splicing pulse lights whose frequencies linearly increase is obtained, thus forming the EHz ultrafast modulation of a distributed feedback fiber laser.

  • Patent number: 11369316
    Abstract: There is provided a system architecture including a PPG hardware module and a MEMS hardware module. The PPG hardware module processes PPG raw data, which is generally composed of analog signals or digital signals. The PPG hardware module filters the raw data for later digital calculation to, for example, find out frequency signals with higher peak values. The PPG hardware module then outputs the selected frequency signals to an MCU for heart rate calculation. The MEMS hardware module receives MEMS raw data from a motion detector made of MEMS elements. The MEMS raw data represents motion status of a user that could possibly affect the heart rate determination result. The MEMS hardware module filters the raw data for later digital calculation to find out frequency signals with higher peak values caused by motion.
