  • Patent number: 11962117
    Abstract: The present disclosure provides a fiber laser light coherent combination system, comprising: a modulator module configured to perform a phase modulation on sub-beams according to pseudo-random sequences orthogonally independent from each other, and perform a frequency shift on a reference beam according to a set frequency; a fiber laser light amplifier module configured to perform a power amplification on the modulated sub-beams; a laser light collimation emission module configured to collimate and output the sub-beams and the reference beam; a combination sampling module configured to perform a combination of the sub-beams and the reference beam which are collimated and outputted, and convert them into an electrical signal; a digital phase modulation and demodulation module configured to perform a demodulation on the electrical signal according to the shifted frequency and each of the pseudo-random sequences, and obtain a phase difference between each of the sub-beams and the reference beam.

  • Patent number: 9683840
    Abstract: A method and a device for continuously detecting thickness of a sheet-type medium in a continuous conveying process can achieve a more accurate and stable detected thickness value. The device for detecting thickness of a sheet-type medium comprises a conveying roller; a detection roller, the detection roller being arranged opposite to the conveying roller, and an elastic displacement existing between the detection roller and the conveying roller; a plate spring, arranged by pressing opposite to the other side of the detection roller relative to the conveying roller; a sensor, arranged above the plate spring; and a thickness calculation unit, calculating a thickness value of the sheet-type medium according to a distance detection value and a standard zero value; and further comprises a zero value correction unit.

  • Patent number: 9561928
    Abstract: A banknote temporary storage unit of a banknote processing device includes a box body, and further includes a controllable telescopic rod having one end configured to be fixed at a transaction port of the banknote processing device and a telescopic end articulated to the box body. The box body is slidably arranged at the transaction port, and in the case that the controllable telescopic rod is at a terminal of a telescoping stroke of the controllable telescopic rod, the box body is located outside the transaction port, and a banknote dispensing space in the box body is in a visible area.

  • Patent number: 9230162
    Abstract: An identification control method and system for a valuable document. The system comprises a collection part, an identification part, a control part, a transmission part and an upper computer. In the identification part, complete identification information about a valuable document is split into basic identification information and high-grade identification information. Only the basic identification information which is required by the control part is sent to the control part, and the information which is not required by the control part is directly sent to the upper computer by the identification part.

  • Patent number: 9224185
    Abstract: Disclosed are a valuable-file identifying method and an identifying device thereof. The identifying method and the identifying device store image data of a valuable file using a fast storage method for image data. The fast storage method for image data comprises: compulsively converting collected single-byte image data into long-integer image data; using N data masks which correspond to each other through a “bitwise AND” operation to extract the long-integer image data in such a manner that N points are extracted from M*N points in each line and one point is extracted from L points in each column, where N is an integer greater than or equal to 2, L and M are all integers greater than or equal to 1; and integrating the data extracted respectively by N data masks through a “bitwise OR” operation to obtain coded image data and store same.

  • Patent number: 9014459
    Abstract: An identification method for a valuable file and an identification device thereof. The method includes the following steps: (1) acquiring an original infrared image, type, denomination and orientation data of a current valuable file; (2) obtaining size data and infrared characteristic data of a corresponding standard valuable file; (3) applying an image projection conversion technology, and correcting the original infrared image to form a second infrared image matched with the size of the standard valuable file; (4) obtaining the infrared characteristic data of the current valuable file from the second infrared image and comparing same with that of the standard valuable file to identify whether the current valuable file is true or false; and (5) outputting the identification result.
