A game controller includes a main body, a detachable electrode, a sensor and a controlling unit. The main body includes a grasping part. The detachable electrode is disposed on the grasping part. The sensor detects whether the detachable electrode is in contact with the grasping part. According to a result of judging whether the detachable electrode is in contact with the grasping part, the controlling unit controls the detachable electrode to generate a corresponding electric shock signal.

Game controller

A touch pen for a capacitive touch screen is provided. The touch pen includes a signal receiver conductor, a signal detecting and adjusting circuit, and a signal transmitter conductor. The signal receiver conductor receives a first touch signal from the capacitive touch screen. The signal detecting and adjusting circuit enlarges the first touch signal to a second touch signal having a standard intensity with a first magnification factor, a second magnification factor and a third magnification factor. The signal transmitter conductor issues the second touch signal to the capacitive touch screen. According to the second touch signal, the capacitive touch screen senses a position of a touch point of the touch pen.

Touch pen

A touchpad controlling method and a touch device using such a method are provided. The touch device is applied to an electronic appliance. The touch device includes a touchpad and a coordinate transformation program. The touchpad is used for detecting a number of touching points in response to the touching gesture on the touchpad and the position of each touching point. If the number of touching points is equal to 1, the electronic appliance is operated in a relative coordinate mode. Whereas, if the number of touching points is greater than 1, the electronic appliance is operated in an absolute coordinate mode.

Touchpad controlling method and touch device using such method

The present invention relates to an input device having an indicating lamp. The input device includes a case and an electronic lighting module. The electronic lighting module includes a printed circuit board, an electronic lighting element and a light guide post. The light guide post has a crooked shape. Due to the crooked shape, the light beams emitted by the electronic lighting element are no longer focused as a spot on the surface of the case.

Input device having indicating lamp

The present invention relates to an input device having a multi-stage indicating lamp. The input device includes a case and an electronic lighting module. The electronic lighting module includes a printed circuit board, a first electronic lighting element, a second electronic lighting element, a light guide post member, a light-shielding member, a lamp cover and a button. By means of the light guide post member and the light-shielding member, the possibility of scattering the light beams is reduced.
