Patent number: 11892293Abstract: A platform gauge instrument and a platform gauge measuring method based on a photogrammetric principle are provided. According to the platform gauge instrument, measuring stations are arranged on both sides of a platform, and the measuring stations on both sides work together to ensure the acquisition of complete platform information. The measuring stations have automatic traveling capability to complete scanning of a whole platform, platform information obtained by the scanning is automatically resolved by a measuring system, and gauge dimensions such as a transverse dimension and a vertical dimension of a platform gauge are resolved through parameters such as object-space coordinates of platform edge points, a space equation of intersection lines of upper surfaces of rails and a measuring cross-section, and common tangent lines of the upper surfaces of two rails on the measuring cross-section, so that resident and real-time gauge high-precision detection of the platform is achieved.Type: GrantFiled: May 17, 2023Date of Patent: February 6, 2024Assignee: NINGBO SPECIAL EQUIPMENT INSPECTION AND RESEARCH INSTITUTEInventors: Faju Qiu, Wei Chen, Jijie Yang, Xiangning Kuang, Gaoyao Ding, Yiyi Zhang, Jianer Wang, Jinhui Yang

Patent number: 11203424Abstract: A mechanical power transmission that pivots about an axis to vary an angle between an input shaft and an output shaft. The mechanical power transmission includes an input gear having an input shaft that couples to a drive shaft, an output gear having an output shaft that couples to a tail rotor, a first intermediate gear rotationally coupled to the input gear, and a second intermediate gear rotationally coupled to the output gear. The mechanical power transmission further comprises a shaft that mechanically couples the first intermediate gear with the second intermediate gear, where a centerline of the shaft is coincident with the axis.Type: GrantFiled: March 13, 2019Date of Patent: December 21, 2021Assignee: The Boeing CompanyInventors: Patrick Darmstadt, Yiyi Zhang, Mark J.

Publication number: 20200038595Abstract: The present invention provides medical syringe for preventing needle-stick injury, wherein an inner diameter of a middle part of an elastic disengaging ring is larger than an inner diameter of a front part and an inner diameter of a rear part. The elastic disengaging ring is located between a distal wall of a syringe barrel and a needle. When the middle part of the elastic disengaging ring plugged onto the conical fitting of the syringe barrel is radially pinched flat, the proximal end of the elastically deformed elastic disengaging ring leans against the distal wall of the syringe barrel, and the front end of the elastically deformed elastic disengaging ring leans against the proximal end of the needle and pushes the needle to move forward, so that the needle is disengaged from the conical fitting of the syringe barrel.Type: ApplicationFiled: February 18, 2019Publication date: February 6, 2020Applicant: SHANGHAI BOQIA MEDICAL DEVICE CO., LTD.Inventors: YIYI ZHANG, ZUREN ZHANG, WEIHUA XU

Patent number: 9561030Abstract: The present invention disclosed a surgical staple (50) and staple pocket (57) for forming kidney-shaped staple therefor, with the staple pocket (57) being recessed inward on the tissue contacting surface of the staple anvil (58), and with M-shaped staple (50) being used, wherein the degree of projection of the middle portion of the back span (51) of the M-shaped staple (50) arranged at the inner circle or arranged at a proximal side of a cutter slot (121) is larger than that of the back span (51) of the M-shaped staple (50) arranged at the outer circle or arranged at a distal side of the cutter slot (121), so that when the staple (50) of the same height are adapted to staple tissues to be stapled of different thickness, staple driver (68) bends the M-shaped staple (50) on the staple pocket (57) to form kidney-shaped staple (50) so as to achieve the operational effect of being able to seal the stapled tissue, to stop bleeding and to heal the tissue therearound.Type: GrantFiled: May 11, 2012Date of Patent: February 7, 2017Assignees: CHANGZHOU KANGDI MEDICAL STAPLER CO., LTD., SHANGHAI CHUANGYI MEDICAL DEVICE TECH.

Patent number: 9216020Abstract: An endoscopic surgical cutting stapler with a chain articulation is provided, in which a joint is implemented by a chain articulation, teeth are provided at two ends of a chain plate of the chain articulation, and teeth of adjacent chain plates in the same row are engaged. Through mesh transmission of engaged teeth of the adjacent chain plates in the same row, an angle of a most proximal chain plate of the chain articulation is gradually multiplied at several stages and transmitted to an end effector. The end effector can rotate for 90° with small drive motion of the operating mechanism, thereby achieving precise placement of the chain articulation after rotation. The end effector can be precisely aligned with a part to be cut and stapled, and a radius of curvature of the chain articulation can be significantly increased.Type: GrantFiled: December 14, 2010Date of Patent: December 22, 2015Assignee: CHANGZHOU KANGDI MEDICAL STAPLER CO., LTD.Inventors: Zuren Zhang, Yikang Jiang, Zhenyu Jiang, Rong Ji, Yiyi Zhang, Weihua Xu, Dongkun Yuan, Qi Yang

Publication number: 20140328762Abstract: Fluorogenic peptide probes specific for a target molecule are provided. Exemplary fluorogenic peptide probes include a peptide labeled with a fluorogenic label, wherein the fluorogenic peptide probe has an unstructured three dimensional conformation in the absence of the target molecule and a structured three dimensional conformation in the presence of the target polypeptide. The structured three dimensional conformation includes an alpha-helix that forms a coiled-coil with the target molecule allowing generation of a detectable signal from the fluorogenic label in response to an exciting amount of radiation.Type: ApplicationFiled: April 6, 2012Publication date: November 6, 2014Inventors: Yiyi Zhang, Steven N.
