Design and development of functional foot for agile and dynamic legged robots
… designs that work on porous surfaces and ferromagnetic surfaces to tackle these challenges in two approaches. Specifically, this work first introduces the foot design that utilizes two different foot pads (a rubber pad and micro-spine arrays), which can be switched based on the slip condition …

Homopolar bearingless slice motors with magnet-free rotors for extracorporeal life support
… relation similar to that of permanent-magnet synchronous machines. For both machines, permanent magnets are located on the stator to provide a homopolar bias flux to the magnet-free rotors. The bias flux passively stabilizes the rotor's axial translation and out-of-plane tilts, thereby …

Investigation of material properties by NMR in low and high magnetic fields
… investigation with a wide range of applications. Magnetic resonance is used in medicine, the oil industry, food industry, for chemical analysis, quality control in industry and construction, analysis of cultural heritage, and materials science, in particular polymer analysis. The unique feature of …

Linear iron-core permanent magnet motor with high force and low acoustic noise
… motors, induction machines, and permanent magnet synchronous motors. The severity of this problem depends on the types of motors and their applications. One exemplary case where the vibro-acoustic noise becomes especially detrimental is iron-core linear motors operating at high acceleration …
