An example keyboard can include: a base with a midpoint, a first end, and a second end opposite the first end; and a plurality of keys arranged on the base, wherein the plurality of keys is positioned to form a curved shape on the base such that the plurality of keys extend from the midpoint of the base towards a user as the plurality of keys extends towards the first end and the second end of the base.

A keyboard device includes plural key structures. Each key structure includes a keycap, a membrane circuit board, a key frame, an elastic conduction element and a connecting member. The membrane circuit board is located under the keycap. The key frame is arranged between the keycap and the membrane circuit board. The key frame includes a frame body and a bottom plate. The bottom plate is arranged between the key frame and the membrane circuit board. The bottom plate includes a perforation. The elastic conduction element is arranged between the keycap and the bottom plate of the key frame. The perforation is covered by the elastic conduction element. The connecting member is arranged between the keycap and the bottom plate of the key frame. The keycap is movable upwardly or downwardly relative to the bottom plate of the key frame through the connecting member.

An electronic device includes an enclosure and a keyboard positioned within the enclosure. The keyboard includes a substrate and a key mechanism. The key mechanism includes a keycap support mechanism, a keycap supported by the keycap support mechanism and movable relative to the substrate, a ferromagnetic component attached to the keycap support mechanism, and a selectively magnetizable magnet. The selectively magnetizable magnet system may include a magnetizable material and a coil configured to selectively magnetize and demagnetize the magnetizable material. The key mechanism may include a collapsible dome biasing the keycap toward the extended position.

Electrical input devices can be produced using a multi-material 3D-printing process. The electrical input devices can include a non-conductive material portion and a conductive material portion. The non-conductive and conductive material portions are integrally formed during a single 3D-printing process. Deformation of the electrical input devices cause an electrical variance of the conductive material portion that is responsive to the deformation. Some electrical input devices described provide digital responses, and some electrical input devices described provide analog responses. The described techniques can be used to manufacture complex finished devices in a single 3D-print run, and, in some examples, without the need for post-processing or assembly.

A system includes a frame and a camera coupled to the frame. The camera includes a switch having an on position and an off position. The switch coupled to the frame wherein when the switch is in an off position a portion of the switch covers the lens and the camera is disable and when the switch is in an on position the portion of switch does not cover the lens and the camera is enabled.

A microelectronic device comprises pillar structures extending vertically through an isolation material, conductive lines electrically coupled to the pillar structures, contact structures between the pillar structures and the conductive lines, and interconnect structures between the conductive lines and the contact structures. The conductive lines comprise one or more of titanium, ruthenium, aluminum, and molybdenum. The interconnect structures comprise a material composition that is different than one or more of a material composition of the contact structures and a material composition of the conductive lines. Related memory devices, electronic systems, and methods are also described.

A keyboard device includes plural key structures. Each key structure includes a base plate, a keycap, a membrane circuit board, a connecting member and an elastic element. The keycap includes a pressing post. The membrane circuit board is arranged between the base plate and the keycap. The connecting member is penetrated through the membrane circuit board and connected between the keycap and the base plate. The keycap is movable upwardly or downwardly relative to the membrane circuit board. The elastic element is arranged between the keycap and the membrane circuit board. The elastic element includes a resilience piece and plural supporting ribs. The plural supporting ribs are arranged between the resilience piece and the keycap. The plural supporting ribs are contacted with the pressing post of the keycap. Consequently, there is a gap between the pressing post and the resilience piece.
