A surgical robot system includes a slave unit and a computing unit. The slave unit includes a robotic arm, a surgical instrument, a cannula and a sensing element. The robotic arm drives the surgical instrument to rotate about a remote center of motion (RCM). The cannula is detachably coupled to a terminal of the robotic arm and defines an axis passing through the RCM. The surgical instrument is detachably connected with the terminal of the robotic arm and extends distally through the cannula, and the sensing element is disposed on the cannula and senses an axial deformation of the cannula. The computing unit determines a radial force acting on the terminal of the surgical instrument, from a force on the cannula sensed by the sensing element, according to the principle of torque balance. This surgical robot system has force feedback capabilities and obtains the radial force acting on the terminal of the surgical instrument directly from a measurement with higher accuracy and not requiring any additional component, providing for reduced structural complexity of the surgical instrument.

The present disclosure describes techniques of processing information flow and synchronously displaying image s, mask frames and comment information. According to the present disclosure, a system processes a first information stream uploaded by a stream pushing terminal to obtain a frame image and mask frame data, the mask frame data corresponding to the frame image and identifying a timestamp offset indicative of a time difference between the mask frame data and a playing timestamp of the frame image. The system synthesizes the frame image and the mask frame data to generate a second information stream; and output the second information stream to a client for synchronously displaying the image frame, a corresponding mask frame, and the comment information.

Embodiments relate generally to methods and systems for detecting and indicating end-of-service-life in disposable filtration masks. Applicant has proposed incorporating end-of-service-life indicators comprising color changing chemicals into the mask. The indicating chemicals may be incorporated into the nonwoven fabric material of the mask, or may be attached to the nonwoven material of the mask, such as by dipping, spraying, or adhering. The color change of the indicating chemicals may indicate to a user that the use life of the mask has been depleted.
