    摘要: Disclosed is keypad circuitry operable to detect a pressed key while reducing electromagnetic interference (EMI). The keypad circuitry is operable to reduce EMI in two ways: a) reducing the voltage swing occurring at the row circuitry and column circuitry of the keypad, and b) reducing the number of signal transitions by restricting the signal transitions to occurring at the column and row corresponding to a pressed key. By limiting signal transitions to occurring only at the row and column corresponding to a pressed key, fewer signal transitions occur, and thus, less EMI is produced. Additionally, reduced voltage swings at the row circuitry and column circuitry results in reduced EMI.

    摘要: A contact element for the intermittent contacting of conductor tracks on a circuit board, in particular, for flexible touchpads, for example for flexible input devices in the automobile industry, is made from a metal foam. The metal foam may be at least partly infiltrated by an elastomeric material which can also be the material of construction of the touchpad. The contact element has a very reliable construction which is particularly suitable for high voltage application. A method for production of the contact element, touchpads/input devices with such contact pads and the use of the contact pads is also provided.

    摘要: The present invention discloses a high voltage resisting keyboard comprising at least one press key on a casing, a circuit board inside the casing, and a metal dome between the press keys and the circuit board inside the casing, wherein the edge of the metal hemisphere of the metal dome is directly connected to an end of an electrode of the circuit board, and the other end of the electrode is connected to an end of a resistor. Thus, when the edge of the metal hemisphere receives the high voltage current, the keyboard is protected by the resistor to avoid the high voltage current from being sent directly to another end of the resistor that is connected to another electronic component to achieve the purpose of protecting another electronic component.
