Balancing of a Haptic Device with a Set of Springs
2021This paper addresses the balancing of a haptic device by using a set of springs. The proposed haptic device is based on a purely translational parallel manipulator. Given the specific application as haptic device, it is necessary to eliminate or minimize the effect of gravity for achieving a suitable positioning and force feedback.

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.

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 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

Effectiveness of the Majzlin spring intrauterine contraceptive device
American Journal of Obstetrics and Gynecology, 1972Abstract Since March 1967, 3,687 first insertions of the Majzlin spring were performed at the State University of New York Downstate Medical Center Family Planning Clinic. Seven different forms of this device, with different degrees of flexibility, made of wire gauges varying from 0.010 to 0.020 inches in diameter, were used. The 14T device made of a

Implementation of CAM physiotherapy device with a virtual spring
Computers in Biology and Medicine, 2008Continuous passive motion (CPM) and continuous active motion (CAM) physiotherapy devices are commonly used to promote rehabilitation of damaged synovial joints. A CPM/CAM device with no resistive CAM-type components is presented. In the CPM mode the electric motor functions conventionally, but in the CAM mode, intelligent use of the motor simulates ...

Tuboovarian abscess and the intrauterine device (Maizlin Spring)
American Journal of Obstetrics and Gynecology, 19732 case histories of severe pelvic infection and tuboovarian abcesses associated with use of the Majzlin Spring intrauterine device are presented. A 30-year-old parous white woman and a 25-year-old parous black woman were admitted to the Brooklyn-Cumberland Hospitals on separate occassions with a history of prolonged fever diarrhea pelvic pain and ...

Recent developments of insertion devices at SPring-8
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2001Abstract The construction of the 25-m long undulator of in-vacuum type was finished successfully and installed into the 30-m straight section of the SPring-8 storage ring. The period length is 32 mm and the number of periods is 780. The maximum field is obtained as 0.59 T at the minimum gap of 12 mm. Although this device is composed of five segments,
