  • Publication number: 20240129043
    Abstract: A real-time vector analysis method for detecting an optical signal with a bandwidth greater than 1 THz includes: mapping, by a time-lens focusing system, a spectrum of a signal under test to different temporal location information; obtaining, by fully broadening an ultrashort pulse by a dispersion, a time domain spectrum of the ultrashort pulse to form a chirped swept frequency source; inputting an out of the signal under test after passing through the time-lens and the chirped swept frequency source to a coherent receiver to realize an interference process and a conversion of an optical signal to an electrical signal, and recovering an intensity information and a phase information of frequency domain of the signal under test from the electrical signal by data acquisition and processing; then recovering a full-field information of time domain of the signal under test by a Fourier inverse transform.

  • Publication number: 20240082490
    Abstract: An infusion line gas removal device and process for its fabrication and use is disclosed herein. The gas removal device includes a gas permeable tubing coupled between first and second couplers, and an impermeable tubing shield encasing the gas permeable tubing between the first and second couplers. The impermeable tubing shield is larger in diameter than the gas permeable tubing and comprises at least one vent and a plurality of supports, the plurality of supports being between the tubing shield and the gas permeable tubing and configured to support the gas permeable tubing within the impermeable tubing shield in a fixed position between the first and second couplers and facilitate passage of gas from the gas permeable tubing to the at least one vent.

  • Patent number: 11695239
    Abstract: An electrical connector includes multiple electrical modules sequentially stacked along a vertical direction. Each electrical module includes an insulating block being arc-shaped, a row of conductors fixed to the insulating block, and a first shielding member. The row of conductors includes multiple first grounding conductors and multiple pairs of first signal conductors arranged on the insulating block along a left-right direction. The two first signal conductors in a same pair of first signal conductors have a same length. The first shielding member has a first main body portion overlapping with a projection of one pair of first signal conductors in the vertical direction. The first shielding member and each conductor bend and extend downward from a top thereof and backward from a front thereof to be arc-shaped. The first contact portions of the row of conductors located on the same electrical module are located on a same horizontal plane.

  • Patent number: 11580668
    Abstract: There is provided an automatic correction method for an onboard camera and an onboard camera device. The automatic correction method includes the following steps: obtaining a lane image with the onboard camera and a current extrinsic parameter matrix, and identifying two lane lines in the lane image; converting the lane image into a top-view lane image, and obtaining two projected lane lines in the top-view lane image for the two lane lines; calculating a plurality of correction parameter matrices corresponding to the current extrinsic parameter matrix according to the two projected lane lines; and correcting the current extrinsic parameter matrix according to the plurality of correction parameter matrices. This can be applied in situations where the vehicle is stationary or travelling for automatic correction on the extrinsic parameter matrix of the onboard camera.

  • Patent number: 11139628
    Abstract: An electrical connector and a method of manufacturing the same are provided. A connecting member is embedded in an insulating body between a side edge of the insulating body and an outer side of a first terminal or a last terminal in a first terminal group, and a gap exists between the connecting member and the first terminal or the last terminal. In other words, the connecting member is not in contact with the first terminal or the last terminal adjacent to the connecting member. Thus, the width of the first terminal or the last terminal is not increased, ensuring the high-frequency transmission rate of the first terminal group, and thereby forming an electrical connector which is capable of facilitating machining without affecting the transmission quality of the terminals, and having a stable structure and high-frequency transmission performance.
