Abstract: A surgical robot includes a fixed frame and a moving frame, each having an open space in a center region and may be formed as a partially open ring. The robot also includes three leg structures connecting the fixed frame and the moving frame, and enabling the moving frame to move relative to the fixed frame. The robot also includes a stabilizer for holding an anatomical structure in the open space of each frame. Each leg structure may include a linear component coupled to the moving frame, a rotary component mounted to the fixed frame, and a connector connecting between the two. Each of the linear component and the rotary component may have a rotary actuator that can be controlled by a computer. The robot may be controllable by a computer to assist a reduction procedure of long bone fractures or pelvis surgery.

Abstract: Systems and methods are provided to detect and determine the location and relative significance of joint damage in structures including bridges, and particularly including accelerated bridge construction (ABC) bridges, based on measured changes in bridge dynamic or static response parameters and model updating methods. These systems and methods may use a detailed finite element model to calculate the sensitivity of joint damages in the structure response parameters for a particular loading configuration and the change of state in the structure obtained through instrumentation and response monitoring of the structure compared to a prior condition of the structure in order to identify potential damages.
