Abstract: An electromagnet device moves two moving contacts from one of a closed position or an open position to the other position when an electric current flows through a coil. A regenerative current coming from the coil flows through a regeneration unit when the coil makes a transition from an energized state where the coil is supplied with an electric current from a power supply to a non-energized state where the coil is supplied with no electric current from the power supply. The control unit causes the regenerative current to flow through a load by controlling a switch when the coil makes the transition from the energized state to the non-energized state.

Abstract: Transparent structures for portions of electronic device housings are disclosed. The transparent structures are formed from multiple layers of transparent (optically clear) materials. The multiple layers can include at least an outer glass layer and one or more other transparent layers that can be either glass or polymer layers. The multiple layers can be bonded together with one or more lamination layers. Accordingly, multi-layer transparent structures that are formed from multiple layers bonded together are able to be not only thin but also sufficiently strong and resistant to damage. The multi-layer transparent structures are well suited for use in consumer products, such as consumer electronic devices (e.g., portable electronic devices).

In the second state, a portion of the ferromagnetic actuator is disposed closer to the first inductor than it is in the first state. Current flows through the second inductor to generate a second magnetic field that attracts the ferromagnetic actuator towards the second inductor causing the ferromagnetic actuator to transition from the first or second state to a third state. In the third state, a portion of the ferromagnetic actuator is disposed closer to the first inductor than it is in the first state.
