  • Publication number: 20190068592
    Abstract: An IoT device has a public device identifier and a private device identifier, where the public device identifier is publicly available and the private device identifier is secret but kept in a secure device database as a correspondence. A registration request is sent from the IoT device to an association server in communication with the device database having an association between IoT public identifier and a corresponding IoT private identifier. The association server which receives the registration request responds with a registration acknowledgement containing, in encrypted form, the private device identifier of the original request and, optionally, the public device identifier associated with the registration request. The requesting IoT device receives the association acknowledgement, decrypts the private device identifier, compares it to its own device identifier, and if they match, sends one or more association requests.

  • Publication number: 20160278618
    Abstract: A method for positioning an endoscope involves installing an auxiliary positioning device on a robot arm, coinciding a terminal of a docking member of the auxiliary positioning device with a remote center of motion defined by the robot arm, inserting and fixing the endoscope inside the auxiliary positioning device, removing the docking member of the auxiliary positioning device so that a terminal of the endoscope coincides with the remote center of motion of the robot arm, and then inserting the endoscope into a body cavity catheter for finalizing positioning. Thereby, the method helps to save time used for preoperative preparation and provides more precise positioning, without using any additional positioning tools to approach the body cavity, thereby reducing the risk of infection.
