A first end of the trunk is connected to the top side of the extension portion and a second end of the trunk is connected to the head. The base member is a unitary piece, and the head of the pivoting portion engages and retains the carrier member of the magnet-carrier assembly.

The present invention relates to a temporary paint brush storage device. The device is designed to hold a paint brush in an upright position within a paint can. The storage device is in the shape of inverted “J” and is coated with a protective material. The storage device is supported by the rim of a paint can and magnetically attaches to a metal ferrule of a paint brush. The storage device may further comprise one or more additional attachment points to store additional paint brushes or painting accessories on the exterior of a paint can.

An electronic device is provided. The electronic device includes a foldable housing which has a hinge structure including a first housing and a second housing, the first housing is connected to the hinge structure and includes a first surface facing a first direction, a second surface facing a second direction opposite the first direction, and a first side surrounding the space between the first second surface, and the second housing is connected to the hinge structure and includes a third surface facing a third direction, a fourth surface facing a fourth direction opposite the third direction, and a second side, the first surface facing the third surface when the electronic device is in a folded state, and the third direction being the same as the first direction when the electronic device is in an unfolded state, a flexible display extending from the first and third surface, and a magnet array.

Enclosures and corresponding magnetic joints. An apparatus includes an enclosure. The enclosure includes a magnetic panel joint formed by: a first panel carrying a magnet and comprising a first pocket; a second panel including a second pocket; and a ferromagnetic shield coupled within the second pocket and couplable within the first pocket via the magnet.

A portable interface system including an interface device, in particular a sensor device, and a base part, wherein the base part includes an attachment area for the interface device and a retraction device, wherein the retraction device is attached to the interface device and is designed to move the interface device into a predefined holding position in the attachment area, wherein the interface device is detachably fixed without tools in the holding position in the attachment area.

The present invention discloses a mobile device positioning structure including, a central magnetic portion on a mounting surface of a fixture for magnetically positioning the back of a mobile device and a ring-shaped magnetic portion formed by two curved clamp arms which are bilaterally symmetrical to each other, and separated and unfolded from each other. After the two curved clamp arms are unfolded relative to the mounting surface, the back of the mobile device is magnetically positioned by the central magnetic portion, and both sides of the mobile device are elastically abutted, clamped and positioned by the two curved clamp arms.

An input device comprising a processor(s), an input element, an electropermanent magnet (EPM) assembly including: a permanent magnet operable to generate a magnetic field; and a magnetizing assembly configured to set a magnetic field generated by the permanent magnet, a first ferromagnetic element, and a second ferromagnetic element. The first ferromagnetic element is configured to part and move away from the second ferromagnetic element as the input element is depressed. When the EPM assembly magnetizes the permanent magnet to a first polarity, the first and second ferromagnetic elements are magnetically attracted to each other and provide an attracting that magnetically opposes the first and second ferromagnetic elements from parting, and when the EPM assembly magnetizes the permanent magnet to a second polarity, the first and second ferromagnetic elements are not magnetically attracted to each other and do not magnetically oppose the first and second ferromagnetic elements from parting.

A pick-up truck bed having controllably magnetized areas for retaining cargo or attachment devices. A first permanent magnet may be attached below the lower surface of the truck bed with a second permanent being rotatable relative to the first permanent magnet to control the magnetic flux provided to retain objects in the truck bed. Alternatively, one or more electromagnets may be provided that may be turned on to retain objects in the truck bed and turned off to allow removal of objects.
