Use of medical devices in the magnetic resonance environment is regulated by standards that include the ASTM-F2213 magnetically induced torque. This standard prescribes five tests. However, none can be directly applied to measure very low torques of slender lightweight devices such as needles. Methods: We present a variant of an ASTM torsional spring method that makes a “spring” of 2 strings that suspend the needle by its ends. The magnetically induced torque on the needle causes it to rotate. The strings tilt and lift the needle.

We use industrial cameras to take images of steel wire ropes under different conditions. We put the images of steel wire ropes in five folders, named as:Camera position step up_1; Camera position step up_2; From dark to light; Rotate(360 degrees); Rotate(360 degrees). Images in different folders come from different sources, explained below: Camera position step up_1:Move the camera from bottom to top to obtain images of different positions of the wire rope.

This paper presents an active disturbance rejection torque control strategy integrated with a Kalman filter for a pneumatic rotary actuator without pressure feedback. The interference from the position system and nonlinearity from friction and air compressibility can lead to chatter and crawl, presenting challenges to achieving precise torque control of pneumatic rotary actuators. A Kalman filter is designed for real-time filtering to address the chattering of active disturbance rejection controller (ADRC) caused by noise of feedback signal.

This data was collected during a validation study of our Torso-Dynamics Estimation System (TES). The TES consisted of a Force Sensing Seat (FSS) and an inertial measurement unit (IMU) that measured the kinetics and kinematics of the subject's torso motions. The FSS estimated the 3D forces, 3D moments, and 2D COPs while the IMU estimated the 3D torso angles. To validate the TES, the FSS and IMU estimates were compared to gold standard research equipment (AMTI force plate and Qualisys motion capture system, respectively).

This dataset is used to design patent and many machines can be designed using this dataset.

This is a very important dataset to do breakthrough. One of the secrets behind invention is revealed in these datasets.

Part of this design, with manually done tabulated calculations were submitted as the proposal design (for innovation challenge) proposed by the author, in the small concept paper to Ministry of Railways, Govt. of India in the year 2017.

 As the Excel files(using LibreOffice) are given, so no paper is written is for it.

The dataset 'sensitivityThreshold(haptic feedback).zip' contains the results of a haptic feedback sensitivity study comparing a novel laparoscopic grasper with 2 conventional graspers. Also grip preference of each participant was stored.The instrument sensitivity was validated by measuring the level at which participants could discriminate force differences applied at the grasper tip with an increasing force level, while the subjects were holding the new instrument and a conventional grasper at the handle grip.
