Abstract: An example apparatus includes a pointing structure, a magnetic-contrast bearing, and drive circuitry. The magnetic-contrast bearing is coupled to the pointing structure, and includes a magnetic array and a substrate that is arranged with the magnetic array. The drive circuitry generates a magnetic field that interacts with the magnetic array and causes control of a pointing position of the pointing structure.

Abstract: Systems are provided for the efficient generation of oscillating magnetic fields below the Low Frequency band. These systems generate such fields by mechanically rotating one or more diametrically-magnetized permanent magnets. In order to reduce friction, the magnets are rotated by applying a motive magnetic field to the magnet(s) to rotate the magnet(s) and thereby generate the oscillating magnetic field. Additionally, diamagnetic repulsion, active magnetic field control, and/or biasing permanent magnets are employed to levitate the rotating magnet(s), further reducing friction and increasing system efficiency. These systems may be employed to generate modulated low-frequency oscillating magnetic fields for communication through seawater, rocks, or other obstacles. Additionally or alternatively, these systems may be employed to generate low-frequency oscillating magnetic fields for navigation and location sensing, resource identification and extraction, or other applications.

Abstract: A microrobot assembly system includes a substrate containing conductive traces formed into at least one holding zone and one moving zone, a diamagnetic layer on the substrate, at least two magnetic structures movable across the diamagnetic layer in response to voltages applied to the conductive traces, wherein the holding zone holds one of the magnetic structures and the moving zone allows another of the magnetic structures to attach to the magnetic structure being held. The system may include a plate spaced above the substrate and rails to guide the moving magnetic structures.
