Coiled Molecules in Spring Loaded Devices
Journal of the American Chemical Society, 2006A cylindrical capsule containing a coiled alkane incorporates spacers. The alkane lengthens and gauche strain is relieved. The spacer can be removed to reset the system to the original state. The system represents a spring-loaded device that operates reversibly in response to acids and bases.

Spring Tension Performance Test Device
2019 5th International Conference on Control, Automation and Robotics (ICCAR), 2019Tensile strength is one of the key parameters of spring performance. The measurement of tensile strength is inseparable from the measurement of spring tensile performance. This paper proposes a spring tension performance test device, which can measure the tensile length and spring tension value curve of the spring by setting the stretching distance and

A Spin‐Orbit Torque Ratchet at Ferromagnet/Antiferromagnet Interface via Exchange Spring
Advanced Functional Materials, 2022The antiferromagnet (AFM) and ferromagnet (FM) interface is a unique branch of magnetics of broad scientific interest. AFMs play an important role in spin‐orbit torque devices based on their ability to generate spin‐polarized current and exchange bias ...

Development of vibration control device with changeable spring constant spring
International Journal of Applied Electromagnetics and Mechanics, 2014Springs are used for various purposes, particularly for vibration control and the removal of machines. However, the use of a spring generates high amplitude at the resonance point; therefore, it is difficult to eradicate vibration from all frequency bands.

Spring over muscle (SOM) actuator for rehabilitation devices
The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005For people affected by stroke, frequent physical therapy has been shown to be an effective form of rehabilitation. To this goal, several home therapy devices have been developed. Many of these devices may benefit from the use of a bidirectional pneumatic muscle actuator.

Spring Suction Device for Pulmonary Needle Aspiration Biopsy
Radiology, 1971A simple spring attachment to provide automatic suction during percutaneous needle lung aspiration biopsy is described. The spring device provides continuous suction while the needle and syringe are rotated to core the lesion. Its use is suggested to facilitate manipulation of the needle, particularly for those who may have difficulty in maintaining ...
