A key entry device including a housing, a keypad array disposed within the housing and including a plurality of keys, a key contact array disposed within the housing below the keypad array and including a plurality of contact pairs, a dome array underlying the keypad array and the key contact array and including a plurality of domes, and a protrusion array underlying the dome array and including a plurality of protrusions, whereby depression of one of the plurality of keys of the keypad array causes a corresponding one of the domes of the dome array to be displaced downwardly and to be deformed by pushing engagement with a corresponding one of the protrusions of the protrusion array into contact with at least one of the contact pairs of the key contact array.

Particular embodiments described herein provide a display that includes a mask that includes a one or more exposed areas, a top electrode, one or more bottom electrodes, a dielectric between the top electrode and the one or more bottom electrodes, and an electrical connection to create a differential voltage between the top electrode and the one or more bottom electrodes.

Particular embodiments described herein provide for a keycap. The keycap can include a protective layer and an active element, where the height of protective layer and the active element is less than six (6) millimeters in height. The keycap can also include a front plane layer, a back plane layer, where the front plane layer and the back plane layer comprise the active element, and an electrical connection through the keycap to provide electrical communication with the active element.

Particular embodiments described herein provide for an electronic device that can be configured to include a plurality of bio-sensing areas, where the bio-sensing areas are located in an area of the electronic device where a user typically comes into contact with the electronic device and a bio-signals engine, where the bio-signals engine can analyze bio signals detected by the bio-sensing areas. These bio-sensing areas can be processed for color, finish and material so as to blend with the electronic device enclosure thereby not degrading the visual appeal.

A secure smartcard reader including a smartcard connector and a flexible printed circuit board wrapped around and at least partially surrounding the smartcard connector and at least partially defining a security volume enclosing the smartcard connector, the wrapped flexible printed circuit board defining on an outer-facing surface thereof a plurality of keypad contacts, the wrapped flexible printed circuit board defining electrical conductors connecting the plurality of keypad contacts to connector pads and the wrapped flexible printed circuit board defining a protective anti-tamper mesh protecting the electrical conductors.

Particular embodiments described herein provide a keycap that includes a plurality of front plane elements, where each front plane element includes a top electrode, a conductive region under each of the plurality of front plane elements, where each conductive region includes a bottom electrode and a top electrode coupling area, where each top electrode coupling area is electrically coupled to a common top electrode node, an electrical path between each top electrode and each corresponding top electrode coupling area such that each top electrode is connected to the common top electrode node, and a dielectric between each top electrode and each bottom electrode.

A load-detecting device 1 includes a load detection sensor unit SU and a base 2 on which the load detection sensor unit SU is mounted, and the load detection sensor unit SU includes an upper surface 47S configured to be pressed by a seat cushion SC, a first electrode 52, and a second electrode 62. The upper surface 47S moves with respect to the mount surface 21S such that an angle of the upper surface 47S with respect to the mount surface 21S changes.

In a first aspect of the present disclosure, a spring plate includes a central portion; a first leg portion projecting outward from an edge of the central portion; and a second leg portion projecting outward from the edge of the central portion. The first leg portion includes a hollow portion that is positioned within an outline of the first leg portion in a top plan view, and the second leg portion includes a hollow portion that is positioned within an outline of the second leg portion in a top plan view.

Embodiments are directed to a dome switch and methods related to the use thereto. In one aspect, an embodiment includes a key cap. The embodiment may further include a domed structure having upper and lower portions. The domed structure may be configured to deform in response to an input force received at the upper portion by the key cap. The embodiment may further include a collar affixed to the lower portion and extending toward the key cap. The collar may resist deformation of the domed surface.

A secure smartcard reader including a smartcard connector and a flexible printed circuit board wrapped around and at least partially surrounding the smartcard connector and at least partially defining a security volume enclosing the smartcard connector, the wrapped flexible printed circuit board defining on an outer-facing surface thereof a plurality of keypad contacts, the wrapped flexible printed circuit board defining electrical conductors connecting the plurality of keypad contacts to connector pads and the wrapped flexible printed circuit board defining a protective anti-tamper mesh protecting the electrical conductors.
