Abstract: The invention provides an electrochemical discharge-assisted micro-grinding device for micro-components of brittle and hard materials. The device includes a micro-grinding tool, grinding fluid, a workpiece, an auxiliary electrode, a processing groove, and a pulsed DC power supply; the processing groove is filled with grinding fluid; the micro-grinding tool, the workpiece, and the auxiliary electrode are immersed in the grinding fluid; the micro-grinding tool is composed of a conductive grinding tool base, an electroplating layer, and insulated superabrasives. The micro-grinding tool is connected to the negative electrode of the pulsed DC power supply; the grinding fluid is composed of H2O2, Na2CO3, EDTA-Fe-Na, and deionized water; the workpiece material is brittle and hard; a large number of micro structures need to be produced on the surface of the workpiece.

Abstract: A link re-establishment method, an apparatus, and a system are provided. The method includes: obtaining, by user equipment (UE), a MAC of the UE based on a NAS integrity key and a first MAC generation parameter, where the first MAC generation parameter includes an identifier of the UE; sending, by the UE, a re-establishment request message to a target RAN, where the re-establishment request message includes the MAC and the first MAC generation parameter; and receiving, by the UE, a re-establishment response message of the target RAN. The UE triggers, by sending the re-establishment request message, a CP functional entity to perform authentication on the UE. This resolves a prior-art problem that an excessively long time is consumed to re-establish a connection to a target RAN by using an RAU procedure, increases a speed of re-establishing a connection between UE and a network, and improves user experience.

Abstract: The present disclosure provides a method and apparatus for generating a front-end code. The method includes: acquiring attribute information of view elements in a target UI view interface; determining child view elements corresponding to a given parent view element based on the attribute information of the view elements; determining, according alternately to row correlation information and column correlation information between the child view elements, nodes at different levels of a DOM, tree corresponding to the parent view element except a root node until each leaf node is an individual child view element, to obtain the DOM tree; and generating a complete front-end code corresponding to the target UI view interface based on the DOM tree.

Abstract: An apparatus for eye surgery may comprise a nozzle having a delivery lumen, an implant bay coupled to the nozzle, an implant disposed in the implant bay, and an actuator coupled to the implant bay. The actuator may comprise a housing; a bore through the housing; a plunger disposed within the bore; and a compression ring. The plunger can be configured to advance within the bore, thereby advancing the implant from the implant bay through the delivery lumen, and the bore can be configured to compress the compression ring as the plunger moves through the bore. In some embodiments, the bore can be configured to increase compression on the compression ring as the first end of the plunger moves through the bore.

Abstract: An optical measurement and calibration method for a pose based on three linear array charge coupled devices (CCD) assisted by two area array CCDs includes the following steps: step 1: preparing devices, and determining cooperative targets, namely three red light-emitting diode (LED) light dots; step 2: arranging measuring devices; step 3: configuring a cylindrical lens of a linear array CCD camera with a cylindrical mirror and an optical filter; and step 4: measuring through a fast capture process, a coarse adjustment calculation process, a fine adjustment calculation process, and a calibration process till coordinates are obtained by means of a fine adjustment. According to the present disclosure, an optical lens based on a telecentric optical path in an image space can fulfill a large field of view (FOV), an extended depth of field (DOF), and low distortion of a system.
