  • Publication number: 20220373616
    Abstract: A system for detecting a connection between two devices includes a first device and a second device. The first device includes a first connection terminal and a first reactance element connected to the first connection terminal. The second device includes a second connection terminal; a first resistance element, and a first frequency generator for allowing a signal to pass through the first resistance element and be applied to the first device via the second connection terminal. The second device further includes a first comparator having both input terminals connected to both ends of the first resistance element, and comparing and outputting a signal of both ends of the first resistance element, and a first control unit for determining whether or not the first connection terminal of the first device is connected to the second connection terminal by means of the output signal of the first comparator.

  • Publication number: 20140305778
    Abstract: An input device for an electronic device includes a floating prevention mechanism that prevents a physical key from being rocked. The input device may include a case, a body that is partially exposed to the outside of the case, a key base that is made of a soft material and coupled to a lower surface of the body, a switch that is positioned below the key base and generates an electrical signal when pressed by a force that is equal to or larger than a predetermined magnitude, and a substrate on which the switch is mounted. The key base may include a pressing protrusion that is formed on a bottom surface of the key base and presses the switch, and a floating prevention unit that is made of a soft material and formed at opposing sides of the key base with respect to the pressing protrusion. The floating prevention unit supports the body to prevent the body from being rocked.
