Abstract: A power transfer system to facilitate the transfer of electrical power between tree trunk sections of an artificial tree is disclosed. The power transfer system can advantageously enable neighboring tree trunk sections to be electrically connected without the need to rotationally align the tree trunk sections. Power distribution subsystems can be disposed within the trunk sections. The power distribution subsystems can comprise a male end, a female end, or both. The male ends can have prongs and the female ends can have voids. The prongs can be inserted into the voids to electrically connect the power distribution subsystems of neighboring tree trunk sections. In some embodiments, the prongs and voids are designed so that the prongs of one power distribution subsystem can engage the voids of another power distribution subsystem without the need to rotationally align the tree trunk sections.

Abstract: The present disclosure relates to trial scleral lenses, and the resulting scleral lenses, designed for the asymmetric shape of the sclera and/or its chiral properties. In some embodiments, the scleral lenses are also designed for the specific asymmetry associated with different scleral diameters. In addition, as discussed herein, the scleral shape can vary with different conditions of the eye. By designing a set of trial scleral lenses that takes into account these different asymmetric properties of the sclera, a clinician can be more efficient, fitting more eyes with fewer subsequent modifications. The resulting lenses will also achieve a better fit.

Abstract: This patent application relates to a feeding device for tubular component, which comprises: a first driver and a first wheel set; and, a second driver and a second wheel set; wherein, the tubular component can be clamped between the first and second wheel sets, and be driven to move under the friction action of the first and second wheel sets; the first wheel set has a plurality of first driving wheels, travelling directions of which are parallel to each other, and form an angle with an extension direction of a clamped portion of the tubular component, the angle being an acute angle; the second wheel set has a plurality of second driving wheels, travelling directions of which are parallel to each other. The technical solution of the present application involves a simple structure, low cost, and ingenious principle, and has applicability to both rigid and flexible tubular components.

Abstract: A flexible endoscope system is provided for use in surgical operation which includes a head part and a control handle detachably connected using first and second docking keys. The head part comprises a shaft, a flexible tip located at a distal end of the shaft, an image sensor module, and drive tendons extending in the shaft for controlling the movement of the flexible tip in multiple degrees of freedom. The control handle includes multiple motors for tensioning or relaxing the drive tendons via a capstan assembly. Control element is provided on the control handle to allow a user to trigger a complex movement of the flexible tip to form an S shape so that a bird-eye view of the surgical site can be obtained by the endoscope system. The detachable connection eliminates the need to sterilize the control handle in which the main electronic components are located.
