Abstract: A gearbox decoupling apparatus and method for powering an accessory system. The gearbox decoupling apparatus employs a worm gear mechanism having an input worm pinion engaged with a worm gear wheel. A threaded rod is engaged with the worm gear wheel. A decoupling adapter is connected to the threaded rod. Rotation of the input worm pinion imparts movement of the decoupling adapter between a first position and a second position. When the decoupling adapter is in the first position, the decoupling adapter is mechanically engaged with a power take-off gear and a power take-off adapter. When the decoupling adapter is in the second position, the decoupling adapter is mechanically engaged with the power take-off gear and disengaged from the power take-off adapter thus allowing an accessory system to be powered by an alternate power source other than a main power source that is permanently connected to the power take adapter.

Abstract: 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.

Abstract: 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.

Abstract: An interface of the needle of a medical syringe and realizes that a conical fitting and a conical inclined surface of a syringe barrel and a conical lip and a conical hole of the needle form an interface of the needle; when the conical hole of the needle is plugged onto the conical fitting of the syringe barrel, the needle is fixed onto the conical fitting of the syringe barrel to achieve the purpose of preventing a needle tip from swinging when the needle pierces a muscle or a blood vessel of a human body, so as to avoid misoperation; and after the medical syringe is used, the conical lip of the needle distal away from the needle tip only needs to be pinched flat, the needle can then be separated from the conical fitting of the syringe barrel of the medical syringe.

Abstract: 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.

Abstract: 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.
