The axial expansion of the elastic bellows artificial muscle is restricted by the chain plate framework to overcome the elastic force of a tension spring to bend, to generate conformal contact between one or more chain plates and an object to be gripped and generate a contact force for a gripping state. With the control of a high-speed on-off valve, the air pressure in an inner cavity of the elastic bellows artificial muscle is accurately controlled to vertically or horizontally grip a cylindrical object, a cuboid object, a spherical object or an ellipsoid object. The flexible finger has adequate flexible adaptability and a simple structure, and is reliable to use, and adapts to differently shaped objects to be gripped and vertically and transversely placed objects.

Abstract: A system for detecting Denial-of-Service (DoS) attacks on one or more user profiles collects a number of invalid sign-on attempts on the one or more user profiles during every time interval. The system determines a number of invalid sign-on attempts on every user profile since the start of the first time interval. The system detects a first DoS attack on a particular user profile if a first number of invalid sign-on attempts on the particular user profile exceeds a single-user profile. The system detects a second DoS attack on multiple user profiles during the first time interval if the increase in the total number of invalid sign-on attempts since the last time interval exceeds a scan-level threshold number. The system detects a third DoS attack on multiple user profiles if the total number of invalid sign-on attempts detected during combined time intervals exceeds a third threshold number.
