An end-effector is disclosed. The end-effector includes a clamp arm and an ultrasonic blade configured to acoustically couple to an ultrasonic transducer and electrically couple to a pole of an electrical generator. The clamp arm includes a clamp jaw, a clamp arm pad, and a cantilever electrode that is free to deflect. The cantilever electrode is configured to electrically couple to an opposite pole of the electrical generator. Also disclosed are configurations where the clamp arm includes a peripheral cantilever electrode and a clamp arm pad extending beyond the electrode, a floating cantilever electrode and a resilient clamp arm pad, an interlocked cantilever electrode plate and a clamp arm pad configured to receive the plate, a laterally deflectable cantilever electrode and a clamp arm pad extending beyond the electrode, and a flexible cantilever electrode and a clamp arm pad extending beyond the electrode.

Deflectable support of RF energy electrode with respect to opposing ultrasonic blade

A non-contact communication method and a communication device are presented. The communication device includes a trusted execution environment (TEE). A first security application and a second security application are provided in a security element of the communication device. The first security application and an application in the trusted execution environment are communicationally connected by means of a first communication channel. The second security application and a near-field communication (NFC) module provided in the communication device are communicationally connected by means of a second communication channel. The first security application and the second security application are communicationally connected by means of a security channel. Using the non-contact communication method and the communication device, a security channel may be established between NFC and a TEE, which may enable NFC non-contact card reading for a TEE application.

Non-contact communication method and communication device

A surgical instrument has an ultrasonic blade that connects to a distal end of an ultrasonic waveguide. A clamp arm assembly is moveable from an opened position for receiving a tissue, toward a closed position for clamping the tissue. A clamp arm actuator connected to the clamp arm assembly directs the clamp arm assembly from the opened position toward the closed position. An outer sheath surrounds at least a portion of the ultrasonic waveguide. The outer sheath includes a cover removably received against a sheath body, and a sheath securement feature able to detachably couple the cover to the sheath body such that the cover can be detached from the sheath body for accessing the ultrasonic waveguide within the outer sheath.

Surgical instrument with removable portion to facilitate cleaning

A deformable segment with combined motion includes a flexible center backbone, the tendons of deformable segment with combined motion, a connecting piece, a proximal disk and a distal disk. The proximal end of the flexible center backbone and the proximal ends of the tendons of deformable segment with combined motion are fixedly connected to the proximal disk. The distal ends of the tendons of deformable segment with combined motion are fixedly connected to the distal disk. The distal end of the flexible center backbone penetrates through the distal disk and then extends into the distal execution segment, and is connected with the end-effector. The deformable segment with combined motion is provided with the connecting piece. The proximal driving segment is provided with proximal driving tendons. The proximal driving tendons penetrate through the proximal disk, and then are fixedly connected with the connecting piece.

Deformable mechanism with combined motion

The present disclosure provides compounds of Formula (III) 

GLP-1R agonists and uses thereof

The present invention relates to a method for access control of a multimedia system to a secure operating system and a mobile terminal for implementing the method. The method includes the steps of: initiating an application access request for selecting a trusted application from a client application of a multimedia system to a secure operating system; making a decision as to whether the client application is a malicious application, and if not, proceeding to a next step, if yes, returning Selection Failure to the client application and performing an interrupt handling; sending the application access request from the multimedia system to the secure system; and acquiring, at the secure operating system, the trusted application based on the application access request and returning the trusted application to the multimedia system. The malicious accesses initiated by a malicious application to a trusted application in a securing operating system can be prevented without switching between systems, and the problem that a trusted application cannot be accessed due to malicious access can be avoided.

A venous valve replacement device includes a stent with a blood flow channel and two leaflets connected to the stent, wherein one side of each leaflet is configured as a fixed edge connected with the stent, and the other side is configured as a movable edge, and wherein the movable edges of the two leaflets cooperates with each other to open or close the blood flow channel, and the movable edges of the two leaflets are provided with flaps that attach to each other in a closed configuration.

Venous valve replacement device

Embodiments of the present invention disclose an application management method for terminals, including: after receiving the application download request sent by the terminal, the application server sends the corresponding application installation package to the terminal. Then, the first verification message sent by the terminal is received, and the first verification message is generated by the terminal according to the content of the received application installation package. After determining that the first verification message is consistent with a stored second verification message, the application server sends an permit-to-install message to the terminal, so that the terminal installs the application according to the received application installation package. Because the application server determines the legitimacy of the application package, it does not need the terminal to verify by using the certificate, thereby reducing the certificate work management for the terminal and improving the efficiency of application installation.

Application management method for terminal, application server, and terminal

The present disclosure relates to user plane link establishment methods. One example method includes sending, by a first base station, an obtaining request associated with user equipment to a second base station, receiving, by the first base station, a response message corresponding to the obtaining request, where the response message includes a peer address associated with the user equipment, and establishing, by the first base station and based on the peer address, a user plane link corresponding to the user equipment.
