Contactless Mechanical Components: Gears, Torque Limiters and Bearings

Machines, 2014
Contactless mechanical components are mechanical sets for conversion of torque/speed, whose gears and moving parts do not touch each other, but rather they provide movement with magnets and magnetic materials that exert force from a certain distance ...

COPIS: A robust and versatile robotic imaging system for the 3D digitization of natural history specimens with photogrammetry

Methods in Ecology and Evolution, EarlyView.
Abstract Ecologists and evolutionary biologists are increasingly turning to 3D models to use in scientific research. Natural history museums are one of the primary sources for specimens used as 3D models, and efforts are underway to digitize their collections using methods like photogrammetry.

Investigation of transmission characteristic for harmonic magnetic gears considering dynamic eccentricity using magnetic equivalent circuit

IET Electric Power Applications
Harmonic magnetic gears (HMGs) have the advantage of lubrication‐free, high speed ratio and high torque density, which make it an attractive solution for safety critical applications. Due to eccentricity caused by machining and assembly, HMG suffers from

Hydraulic In Vitro Characterization of MR‐Conditional Blood Pumps

Artificial Organs, EarlyView.
Cardiac surgery in neonates requires close placement of cardiopulmonary bypass machines due to limited blood volume, complicating MR compatibility. This study introduces three MR‐conditional blood pump prototypes. None interfered with MRI imaging, though RF‐related sensor effects remain untested.

Magnetic gear and coupling using permanent magnet.

Journal of the Magnetics Society of Japan, 1987
Recently, permanent magnets have shown excellent practical performance characteristics. A description is given of a magnetic device with rotational ratio n constructed using a permanent magnet. When n ≠ 1, it operates as a magnetic gear and when n = 1, it operates as a magnetic coupling. As a magnetic gear, we used SmCo5 for the permanent magnet.

Points vs. passes: A comparison between electric fishing techniques for sampling fish populations in upland headwater streams

Journal of Fish Biology, EarlyView.
Abstract Point‐abundance sampling by electric fishing (PASE) was compared with single‐pass (DF1) and triple‐pass depletion sampling (DF3) electric fishing on the same reaches of four headwater streams sampled over multiple years in the Ribble catchment, UK. Juvenile salmonids, mostly brown trout Salmo trutta with some Atlantic salmon S.

Analysis and Numerical Calculation for Several Basic Characteristics of Coaxial Magnetic Gears Applied in Robots

Jixie chuandong
Due to its natural characteristics, coaxial magnetic gears are still difficult to be directly applied to industrial robots. Some key basic characteristics such as torque density, transmission ratio, null-space, backlash and torsional stiffness, and ...

Stigma Management within and between Levels

Journal of Management Studies, EarlyView.
Abstract We respond to recent calls to connect our understanding of stigma across and between levels of analysis by investigating how stigma management strategies to the same stigma vary and relate in nested industry, organizational, and individual actors.
