  • Publication number: 20140354604
    Abstract: A waterproof stylus is provided. The waterproof stylus comprises a hollow pen body. A circuit board is formed within the hollow pen body and has at least one switch. The hollow pen body has an opening, and a button is formed at the opening. The button abuts the switch of the circuit board so that when the button is subjected to pressure, the switch of the circuit board is synchronously triggered. Thereby the circuit board generates an electrical signal to the touch panel, which the waterproof stylus cooperates with. There is a waterproof member formed between the hollow pen body and the button, and the waterproof member seals the opening of the hollow pen body to block external water and air from getting into the hollow pen body and damaging the control unit. Therefore, the stylus of the present invention provides a good waterproofing effect.

  • Publication number: 20140327657
    Abstract: An input device for a touch interface is formed of a main body having an opening, a sensor mounted to the main body, a moveable assembly movably mounted to the main body and having a driven member and a contact member, and a resilient member mounted and stopped against between the movable assembly and the main body. The contact member has an end portion and is mounted to the driven member. The driven member is mounted to the main body. The end portion extends out of the main body through the opening. The driven member and the sensor interact with each other to make the sensor generate an electric signal corresponding to the position of the driven member when the movable assembly is moved relative to the main body. In this way, the input device can accurately control operational force to faithfully reflect the touch perception.

  • Patent number: 8274408
    Abstract: A USB keyboard arrangement having N-keys rollover and the method thereof mainly make use of rearranging a keycode of a firmware program of the USB keyboard through sets of bit maps to control each key thereon. After modifying a matrix, each key within a certain key-area can favorably avert from key ghosting existed in the matrix circuit. Therefore, when all keys in the key-area are concurrently pressed, isolated signals of the keys can be simultaneously sensed. While alternatively adjusting the firmware program through the above methods and adapting the methods to the prior art to split the keys in the key-area of the matrix from the crosspoints of key ghosting, the key-area of the USB keyboard can be provided with concomitantly sending isolated signals.
