Aspects of this disclosure relate to adjusting fluid flow using magnetically sensitive particles. Fluid can flow through an opening in a container. Magnetically sensitive particles can be confined within the container. A magnetic field can be applied to move the magnetically sensitive particles in the container to adjust flow of the fluid through the opening.

Flow adjustment based on particle movement in response to magnetic field

Aspects of this disclosure relate to particles that can move in response to a magnetic field. A system can include a container, particles within the container, and a magnetic structure integrated with the container. The magnetic structure can magnetically interact with both an external magnetic field and the particles. Related methods are disclosed including magnetic field detection methods based on detection of particles within a container.

Magnetically sensitive particles and magnetic structure

Aspects of this disclosure relate to one or more particles that move within a container in response to a magnetic field. A measurement circuit is configured to output an indication of the magnetic field based on position of the one or more particles.

A magnetic device may include a magnetic structure, a device structure, and an associated circuit. The magnetic structure may include a patterned layer of material having a predetermined magnetic property. The patterned layer may be configured to, e.g., provide a magnetic field, sense a magnetic field, channel or concentrate magnetic flux, shield a component from a magnetic field, or provide magnetically actuated motion, etc. The device structure may be another structure of the device that is physically connected to or arranged relative to the magnetic structure to, e.g., structurally support, enable operation of, or otherwise incorporate the magnetic structure into the magnetic device, etc. The associated circuit may be electrically connected to the magnetic structure to receive, provide, condition or process of signals of the magnetic device.

A transformer based digital isolator is provided that has improved immunity to common mode interference. The improved immunity is provided by placing the transformer in association with an H-bridge drive circuit, and taking additional effort to tailor the on state resistance of the transistors to control a common mode voltage at the transformer.
