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 ...

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

A Spring-Loaded Constant Force Exercise Device
Advances in Bioengineering, 2001Abstract Bone mineral density loss has been observed in astronauts who have spent a significant amount of time in a micro-gravity environment [1]. The lack of mechanical stress placed on the bones while in this environment is a major factor in the decrease in bone mineral density.

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 ...

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,

Molecular Springs: Integration of Complex Dynamic Architectures into Functional Devices
Angewandte Chemie International Edition, 2020AbstractMolecular/supramolecular springs are artificial nanoscale objects possessing well‐defined structures and tunable physicochemical properties. Like a macroscopic spring, supramolecular springs are capable of switching their nanoscale conformation as a response to external stimuli by undergoing mechanical spring‐like motions.

A damping device based on bistable springs
2012 IEEE 4th International Conference on Nonlinear Science and Complexity (NSC), 2012A device for earthquake energy dissipation in shear-type structures is introduced. The idea is basically to employ chains made of bistable springs, that exhibit hysteretic behavior.
