A detachable supporting device includes a base, an external component and a supporting portion. The base is put on a holding surface. The external component is detachably disposed on the base. A bar of the external component has a first end and a second end. A first magnetic member is disposed on the first end. A second magnetic member is disposed between the first end and the second end. The supporting portion is connected to the base. The supporting portion includes a first magnetic unit and at least one second magnetic unit. The first magnetic unit and the at least one second magnetic unit are disposed on different sides of the base respectively, wherein the first magnetic unit cooperates with the first magnetic member to provide a magnetic attraction force and the second magnetic unit cooperates with the second magnetic member to provide a magnetic repulsion force.

An external component of a prosthesis, including a first module including a functional component and first structure including magnetic material. The first module is configured to be retained against skin via a magnetic field at least partially generated by a magnet implanted in a recipient that interacts with the magnetic material of the first structure, the first module including a skin interfacing surface configured to interact with skin of the recipient when the first module is retained against the skin of the recipient, a second module including a second structure including magnetic material configured to enhance magnetic retention of the external component to skin of a recipient, wherein the second module is removably attached to the first module and visible from an outside of the external component when the second module is attached to the first module and when viewed from a side opposite the skin interfacing side.

A dampening system combined between a mounting bracket and a block oriented along an x-axis. An electrical connector of a pair of electrical connectors combined to the block for relative movement about a y-axis and a z-axis to combine with the other electrical connector on the magnetic chuck of a pallet changing system.

A system for connecting and monitoring a magnetic operator interface assembly. The assembly can provide protection of an operator interface by limiting glare, UV damage, and exposure to rain. It can also protect the operator interface from high pressure cleaning equipment. The assembly is removably magnetically mountable to a sealed enclosure without breaching the enclosure's seal. The magnetic operator interface assembly can withstand operational forces, staying at a magnetically fixed position and without becoming accidentally detached. It is also easy to intentionally install and remove. The system may include sensors that can inform a local or remote dashboard about the status of the magnetic operator interface assembly, such as whether it is installed and whether the cover is open or closed. The system may also include a locking system to prevent tampering and limit access to the operator interface.

Devices for detachable attachment to a ferromagnetic object and/or surface are disclosed. The device may comprise a core housing defining a pocket, a magnet disposed in the pocket, and a baseplate fixed to the magnet sheet assembly. The baseplate may include a pivot portion that engages a corresponding portion of the core housing to form a hinge joint such that the baseplate and the magnetic sheet assembly selectively pivot about a pivot axis of the hinge joint relative to the core housing. The camming mechanism may apply a camming force to a portion of the baseplate and the camming force may urge the magnet and the baseplate to pivot about the pivot axis of the hinge joint.

A magnetic alignment assembly can be incorporated into an electronic device to facilitate alignment with another device. The magnetic alignment assembly can include a main magnet (e.g., a square or rectangular magnet) having a magnetic dipole in an axial direction and a ring magnet coaxial with the main magnet. The ring magnet can be smaller than the main magnet. The ring magnet can be positioned between the main magnet and an interface surface.

An earphone box includes a box body and a box magnet. The box body defines an accommodating groove configured to accommodate the earphone, and the accommodating groove is provided with an interface configured to be electrically coupled to the earphone. The box magnet is mounted on the box body and configured as a multipole magnet, the earphone is provided with an earphone magnet with the same number of poles as the box magnet, and the earphone magnet attracts and couples with the box magnet.

Described herein are percussion instruments and drums, such as snare drums. The drums include a throw-off device with a handle attached to a mount, which itself can be attached to a drum sidewall. One of the handle and the mount includes a magnet while the other includes a magnetic portion for magnetic engagement with the magnet. The magnetic engagement can be used to bias the handle toward or into a desired position.

An earphone is provided, the earphone includes a main body and an add-on unit, and the add-on unit is removably disposed on the main body using magnetic attraction force.

A magnetic ornament system includes: a mounting structure with a mounting surface; a magnetic plate, including a plate body, an adhesive material, and a protective member; and a magnetic ornament, including a magnet, a connector member, and an ornament assembly; such that the magnetic plate is positionable on the mounting surface of the mounting structure, such that the magnetic ornament is detachably connectable to the magnetic plate.
