A cap-covered keyboard apparatus is disclosed. The proposed cap-covered keyboard apparatus includes plural independent keycaps, each of which has a main body with a top surface, and plural cover layers, each of which at least covers the respective top surface of the corresponding main body, and has a first surface attached to the top surface and a second surface printed with a character (or symbol), wherein the plural cover layers are independent from one another.

A key button and a method of manufacturing the same are provided. The key button includes an upper surface, a side surface formed at a certain height along a border of the upper surface, and at least two worked surfaces formed to have a certain slope in a boundary portion between the side surface and the upper surface, wherein at least one first worked surface and at least one second worked surface are formed such that a shortest distance between the upper surface and the side surface differs from each other.

A method for manufacturing keycaps of a capped keyboard apparatus is disclosed. The proposed method includes: (a) providing a cover layer and plural keycap main bodies, wherein the cover layer includes plural units, and each the unit has an upper surface with a character; (b) putting the plural keycap main bodies on a fixture; (c) shaping the cover layer on the fixture and attaching each the unit to a corresponding one of the plural keycap main bodies; and (d) cutting the cover layer to obtain plural keycaps independent of one another.

Implantable medical systems include implantable medical leads that have magnetic orientation-independent magnetically actuated switches that are placed in the conduction path to the electrode of the lead. Thus, regardless of the orientation of a substantial magnetic field like that from an MRI machine to the lead and switch within the lead, the switch opens when in the presence of that substantial magnetic field. The switch may be placed in close proximity to the electrode such that the opening of the switch disconnects the electrode from the majority of the conduction path which thereby produces a high impedance for RF current and reduces the amount of heating that may occur at the electrode when in the presence of substantial levels of RF electromagnetic energy as may occur within an MRI machine.

There is disclosed in an example a key having a tactile element; and a flexible and conductive external element disposed over the tactile element. There is also disclosed an example method of manufacturing the key, and an electronic device comprising a plurality of active keys, including at least one of the key.
