Article Synopsis
  • The paper presents a new method for determining the relative rotation angle between two spacecraft or aircraft cabins during automated assembly using distributed vision technology.
  • It utilizes two sets of cameras to capture images from different angles of mating features like dowel pins and holes, which are then analyzed to calculate the relative rotation.
  • A practical registration process involving an auxiliary device is introduced to accurately align the cameras, achieving a measurement precision of 0.02° over a distance of 340 mm.

Introduction: Compensatory movements usually occur in stroke survivors with hemiplegia, which is detrimental to recovery. This paper proposes a compensatory movement detection method based on near-infrared spectroscopy (NIRS) technology and verifies its feasibility using a machine learning algorithm. We present a differential-based signal improvement (DBSI) method to enhance NIRS signal quality and discuss its effect on improving detection performance.

Contralateral controlled functional electrical stimulation (CCFES) can induce simultaneous movements in patients' bilateral hands. It has been clinically proven to be effective in improving hand motor control and dexterity. sEMG and bending sensor-based data gloves for detecting patients' motor intent have been developed with limitations.

Objective: This paper aimed to develop an orthosis to apply a compensating force to improve the stability of the glenohumeral joint without resisting arm movement.

Methods: The proposed orthosis was based on a parallelogram structure to provide a pair of compensating forces to the glenohumeral joint center. Theoretical analysis was used to evaluate the additional moments caused by glenohumeral joint center shifting.
