Haptic Actuator
A haptic actuator may include a housing that includes first and second shells. The first shell may define a first tab and the second shell may define a second tab. The housing may also include a plastic end portion positioned between the first and second shells. The plastic end portion may define recesses that receive the first and second tabs. At least one coil may be carried by the housing. A field member may be movable within the housing responsive to the at least one coil. A flexure may be coupled to the plastic end portion and the field member.

Support structure for supporting flexible display screen, and flexible display screen module
A support structure for supporting a flexible display screen includes: a plurality of electromagnets and a controller electrically coupled to the plurality of electromagnets. Each electromagnet has a first surface and a second surface. The first surface is configured to be attached and secured to a flexible display screen so as to support the flexible display screen, and the second surface is at an acute angle to the first surface. When the flexible display screen is extended, the controller controls two adjacent electromagnets to repel each other. When the flexible display screen is bent, the controller controls two adjacent electromagnets to attract each other.
Lifting device
A lifting device includes a base body. The base body includes a supporting surface and defines a cavity. The cavity extends through the supporting surface. The lifting device further includes a magnetic bar, a spring, and a coil in the cavity. The spring includes a first end fixed to an end of the magnetic bar away from the supporting surface and a second end fixed on a wall of the cavity. The coil surrounds the magnetic bar. When the coil is applied with a voltage to generate an electromagnetic induction, the magnetic bar is driven to move out of the cavity from the supporting surface or move to compress the spring.
Vapor impermeable solenoid for fuel vapor environment
A vapor impermeable solenoid for a fuel tank isolation valve assembly an outer housing defining an inner cavity, windings configured to generate a magnetic flux when energized, and a flux collector configured to direct the magnetic flux. An armature tube is disposed within the inner cavity inboard of the flux collector and formed of a magnetic and vapor impermeable material configured to prevent fuel vapor molecules from passing therethrough. A pole piece is disposed within the armature tube, and a magnetic armature is disposed within the armature tube and operably coupled to a seal configured to selectively seal a passage that allows fuel vapor to pass to a purge canister. The magnetic armature is configured to move from a first position to a second position when an electric current is applied to the windings.
