A responsive material having an elastomeric matrix in which ferromagnetic particles are dispersed so as to have a predetermined magnetization pattern which, when exposed to an external magnetic field, changes the shape of the responsive material from an initial shape to a predetermined transformed shape dictated by the magnetization pattern. An initial shape of the responsive material is formed by direct ink printing while applying magnetic fields to a dispensing nozzle to align the particles and gives rise to the desired magnetization pattern.

A bi-stable solenoid includes a housing, a wire coil, a permanent magnet, an armature, a pin, and a spring. The wire coil is arranged within the housing. The armature is slidably arranged within the housing and is moveable between a first armature position and a second armature position. The pin at least partially extends out of the housing and is slidably engaged by the armature. The spring is biased between the armature and the pin. When the pin encounters an intermediate position between a retracted position and an extended position due to the pin engaging an obstruction, the spring is configured to maintain a biasing force on the pin until the obstruction is removed.

An attachment mechanism adapted for use to connect a vehicle headliner with a vehicle header is provided. The attachment mechanism includes a locating block that is adapted to be inserted into an opening in the header of a vehicle. The attachment mechanism includes a base member that devises a center portion and a pair of troughs adjacent the edges of the center portion. The locating block extends from the center portion of the base member. The attachment mechanism includes a plurality of magnets disposed in the troughs and adapted to connect with the header of the vehicle. The attachment mechanism connects to a center check and is helpful in installing the center check with the opening in the vehicle's header.

De-magnetization protection is provided for electro-permanent magnets during information handling system manufacture and use by monitoring thermal conditions at the information handling systems to detect a thermal state associated with de-magnetization and commanding the electro-permanent magnets to an off state so that both magnets in the electro-permanent magnet have opposing polarities. The opposing polarities tend to stabilize magnet polarity to prevent de-magnetization during increased temperatures. Normal operations are then re-enabled once temperatures decrease.

A product includes an array of cold spray-formed structures. Each of the structures is characterized by having a defined feature size in at least one dimension of less than 100 microns as measured in a plane of deposition of the structure, at least 90% of a theoretical density of a raw material from which the structure is formed, and essentially the same functional properties as the raw material.

A superconducting joint arrangement for superconducting magnets, having an elongate joint arranged between superconducting filaments of superconducting wires of one or more superconducting coils, and excess wire provided between the elongate joint and the one or more superconducting coils.

A gripping device for the gripping, holding and guiding of in particular bottle-like containers includes at least one gripper arm pair of a first gripper arm as well as a second gripper arm of complementary form to the first gripper arm, wherein the gripper arms each include a respective base body and gripping section; at least one spring for closing the gripper arm pair from an open position into a gripping position as well as at least one cam for opening the gripper arm pair from the gripping position into the open position. The at least one spring or the at least one cam is thereby arranged on the gripping device so as to be replaceable.

An electronic device includes a display which is foldable at a folding region of the display, a housing which is foldable together with the display, the housing including a first housing and a second housing, and a sensor which is on the first housing and detects a magnetic field, and a hinge structure which corresponds to the folding region of the display, is foldable together with the display and hingedly connects the first housing and the second housing to each other, the hinge structure including a magnet which is slidable along the first housing. Folding of the hinge structure includes folding of the housing together with folding of the display and sliding of the magnet relative to the sensor.

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.

The disclosure relates to a 3D printer using a screw extruder, including a housing including a driving motor, a dispenser in which raw materials are stored and including a nozzle through which raw materials are sprayed, a screw extruder including a screw forming unit arranged inside the dispenser, having a rod shape, and including a spiral screw formed on an outer circumferential surface, and an extension portion extending from the screw forming unit to outside of the dispenser, and an accommodating portion provided in the housing and to which the dispenser is coupled, wherein the dispenser is detachably coupled to the accommodating portion of the housing.
