A driver circuit is provided to connect a charged capacitor through a switch to the inductive windings of an electromagnet for a haptic feedback application. A feedback circuit provides an indication of the current supplied. When the current reaches a desired level, the current is cut off, rather than being controlled. The cutoff level can be slightly below the desired level to allow the desired level to be reached with overshoot. A diode is provided in parallel with the electromagnet winding when the current is shut off, providing a recirculation path that prevents the current from being discharged, thereby dissipating less energy than classical solutions.

Aspects of the invention include a computer peripheral device comprising an input element that operates based on a performance characteristic, an electropermanent magnet (EPM) assembly including a permanent magnet configured to generate a magnetic field and a magnetizing assembly configured to set an intensity of the magnetic field generated by the permanent magnet, and a magnetorheological (MR) material coupled to the input element. The MR material has a viscosity that changes based on the magnetic field and affects the performance characteristic of the input element.

This invention relates to a washable multi-component magnetic floor mat with a hidden base component. The floor mat contains a textile component and a base component. The textile component and the base component are attached to one another by magnetic attraction. The magnetic attraction is provided by incorporation of magnetic particles in both the textile and base components. The textile component is designed to be soiled, washed, and re-used, thereby providing ideal end-use applications in areas such as building entryways. The present invention eliminates the need to wash the base component of the floor mat which results in environmental, cost and labor conservation. Alignment and deployment of the textile component with the base component in an efficient manner is also described herein.

A rotational operation unit includes a rotational operation member that is rotatable, an annular magnet configured to integrally rotate with the rotational operation member, and a magnet holding member configured to rotatably hold the magnet and including an undulated portion configured to generate a click sense as the rotational operation member rotates. The magnet includes a positioner configured to determine a position relative to the magnet holding member.

Aspects of the disclosure provide apparatuses, methods for controlling the apparatuses, and terminal devices containing the apparatuses in the field of mobile solutions. In an example, an apparatus includes a magnetic moving structure and a functional module. The magnetic moving structure has a fixed part, a moving part configured to be movable along a specified trajectory of the fixed part, and a magnetic part. The functional module is connected with the moving part and is configured to move with the moving part. The magnetic part includes a first magnet located on the fixed part and a second magnet located on the moving part and the magnetic part is configured to generate a magnetic force to move the moving part along the specified trajectory.

An aerosol generating system includes an aerosol generating device and a charging case for charging the aerosol generating device when it is received in the case. The aerosol generating device includes a device battery; a heating chamber including a lid arranged to move between an open and closed position to allow a consumable to be received in the heating chamber. The charging case includes a case battery; a receiving means for receiving the aerosol generating device in a charging position within the case. When the aerosol generating device is received in the charging position: the device battery is connectable to the case battery to charge the device battery; and the lid of the heating chamber is moveable to allow a consumable to be inserted or removed from the heating chamber by a user.

A magnetic deformable member includes a magnetic portion formed of a magnetic elastic body, and a base portion formed of a non-magnetic elastic body to cover at least a side surface of the magnetic portion. At least the magnetic portion has a magnetic deformable portion in which shape deformation is caused by application of a magnetic field. The magnetic deformable portion is provided at a boundary-side end portion on the boundary with the base portion. A display portion in which the shape deformation is displayed is provided on a front surface s1 of the magnetic deformable member. With the magnetic deformable member, a tactile feel or viewability of the display portion can be varied by deforming the boundary between the magnetic portion and the base portion.

An energy storage device includes multiple bulk superconductor rings and at least one superconductor wire coil between the multiple bulk superconductor rings. The multiple bulk superconductor rings and the at least one superconductor wire coil are interconnected to define a closed geometric shape.
