An electromagnetic actuator device, the device including an electromagnet including a coil, and a magnetic core including a first portion extending from a front face of the coil, and a second portion extending from a back face of the coil bending back along the coil toward the front face of the coil, and a plate placed such that a first portion of the plate parallels the first portion of the magnetic core and a second portion of the plate parallels the second portion of the magnetic core. Related apparatus and methods are also described.

An electromagnetic solenoid assembly is disclosed. The solenoid assembly includes a cup-shaped ring defining a pocket for an annular coil, and including a radially extending portion, a radially inner axially extending flange, and a radially outer axially extending flange. An axially outer end of the radially outer axially extending flange includes a first inclined surface and an axially outer end of the radially inner axially extending flange includes a second inclined surface. A ring-shaped armature includes a radially outer portion and a radially inner portion. An axially outer end of the radially outer portion includes a third inclined surface and an axially outer end of the radially inner portion includes a fourth inclined surface. Pairs of the inclined surfaces are aligned substantially parallel to each other. A distance between the ring-shaped armature and the cup-shaped ring is variable based on energizing the annular coil.

An image sensor substrate includes an insulating layer including a first open region; and a first lead pattern part disposed on the insulating layer. The first lead pattern part includes: a first pattern part disposed on the insulating layer; a connection portion extending from the first pattern part; and a second pattern part connected to the first pattern part through the connection portion. The second pattern part and the connection portion are disposed to fly on a region not overlapped with the insulating layer in a vertical direction.

An electromagnetically actuated, bistable locking device is disclosed. The locking device has a lock pin that is moveable substantially along a longitudinal axis between an extended position and a retracted position, at least one permanent magnet with two pole ends, at least one electromagnet having first and second ends and electromagnetically actuated in one of the extended and retracted positions of the lock pin, a mechanical interconnection between the pin lock and the at least one permanent magnet for moving said pin lock between the extended and the retracted positions of the lock pin at the actuation of the electromagnet. The inventive idea lies in that if the permanent magnet abuts by one of its faces on the end of the magnetic core of the electromagnetic solenoid, then this configuration allows the exploitation of the magnetic forces at a maximum efficiency in both the energized state and the de-energized state.

A detent solenoid includes an armature assembly with a groove, a coil arranged for displacing the armature assembly, and a detent arranged for seating in the groove. In an example embodiment, the groove includes a first axial side having a toroidal shape and a second axial side, opposite the first axial side, having a conical shape. In some example embodiments, the armature assembly includes an armature and a shaft fixed in the armature, and the groove is disposed in the shaft. In an example embodiment, the armature is made of a ferrous material.

A lens driving device related to the field of driving devices and includes a lens assembly and a driving module for driving the lens assembly to move. The driving module includes a first driving module and a second driving module. The lens assembly is accommodated in the first driving module. The second driving module is sleeved on one side of the first driving module away from the lens assembly. The lens assembly is driven by the first driving module and the second driving module that realize movement in multiple different directions, so the lens assembly accommodated in the first driving module realizes movement in multiple directions, thereby achieving good image stabilization effect.
