An electromagnetic actuator device has at least one stationary spool unit (4), which can be energized, and at least one armature unit (7), movable along a displacement axis (V) and with respect to the spool unit (4) in reaction to the spool unit (4) being energized. The armature unit (7) can be displaced between a parked position and an actuating position in an output drive direction along the displacement axis (V) in order to interact with an actuating element, which can be a camshaft disposed on the output side of the armature unit (7), and can be rotated about the displacement axis (V). A spring member (14) supported against an abutment component (16) is preferably disposed in a torque-proof manner and allocated to the armature unit (7) in such a manner that the spring member (14) applies a spring force to the armature unit (7) during a displacing movement in the output drive direction while simultaneously at least partially relaxing and applying a spring force to the armature unit (7) when in the actuating position. It is intended that the spring member is supported against the abutment component (16) by a rotation decoupling member (15) for decoupling a rotational movement of the armature unit (7) from the spring member (14) about the displacement axis (V) at the armature unit (7) and/or for decoupling a rotational movement of the spring member (14) about the displacement axis (V) from the abutment component (16).

A wireless power reception device can include a first shielding member; a mounting member on the first shielding member; a short-range communication coil on the mounting member; a second shielding member inside the short-range communication coil; a wireless charging coil inside the short-range communication coil; and an alignment hole outside the wireless charging coil, in which the alignment hole penetrates through the first shielding member and the mounting member.

The wearable magnetic pressure point device disclosed herein may comprise, at least, a main body assembly, a strap assembly, a pressure point assembly, and a fluid disc. Such a device contemplates the use of resilient, flexible, and magnetic materials and is suitable for wearing. The purpose of the device is to allow a user to apply acupressure as needed, especially to the PC6 and TW5 locations around the wrist. The device is intended to be completely adjustable for different user needs, and resilient so that the device is resistant to weakening and a user may continue to apply consistent pressure over time. In certain embodiments the user may even apply pressure to the PC6 and TW5 locations simultaneously.

A method of continuously variable valve duration (CVVD) location learning may include when a controller determines necessity of position learning for short duration and long duration of a CVVD system, performing conditional application re-learning control in which the position learning is performed in a situation in which validity determination of system environment condition for CVVD hardware and validity determination of vehicle environment condition for engine operation information of an engine are satisfied.

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 magnetic trap is configured to arrange at least one diamagnetic rod. The magnetic trap includes first and second magnets on a substrate that forms the magnetic trap defining a template configured to self-assemble diamagnetic material. Each of the first and second magnets extends along a longitudinal direction to define a magnet length, and contact each other to define a contact line. The first magnet and the second magnet have a diametric magnetization in a direction perpendicular to the contact line and the longitudinal direction so as to generate a longitudinal energy potential that traps the diamagnetic rod along the longitudinal direction.

A plunger includes an elongate plunger body which is at least in part cylindrical and a plunger head at one end of the plunger body. The plunger body has a magnet-interface body portion which has a non-cylindrical cross-section perpendicular to a longitudinal axis of the plunger body. A magnetic latching solenoid actuator using such a plunger is also provided, as is a method of improving the performance of a magnetic latching solenoid actuator.

A sensor system comprises a magnetic field generator and a sensor device arranged at a distance from said magnetic field generator and adapted for measuring or determining at least one magnetic field component and/or at least one magnetic field gradient component. The magnetic field generator comprises a multi-pole magnet having a number N of pole pairs that are axially magnetized to generate an N-pole magnetic field that is substantially rotationally symmetric around an axis. The magnet comprises a plurality of grooves and/or elongate protrusions that are arranged in a rotationally symmetric pattern around the axis to provide a substantially constant magnetic field gradient in a central region around said axis.

Devices configured to direct heat flow are disclosed, as well as methods of forming thereof. A device may include a self-assembling heat flow object. The self-assembling heat flow object may include a material having one or more self-assembling properties that cause the material to react to an environmental stimulus and one or more thermal pathways. An application of the environmental stimulus causes the self-assembling heat flow object to deploy and arrange the one or more thermal pathways for directing thermal energy to one or more locations.
