Abstract: A welding wire feeding device includes a base, a fixing post, a pressing member, a motor, and a conveying mechanism. The pressing member is pivotally connected with a driven wheel. A tension spring is provided between the fixing post and the pressing member. A shaft portion of the motor is pivotally connected with a driving wheel. The conveying mechanism is coupled to the base and has an air hole. The base is formed with a first passage and a second passage connected with a gas cylinder. The length of the conveying tube of the conveying mechanism can be adjusted by pressing. A wire is sandwiched between the driving wheel and the driven wheel through the tension spring. The motor drives the driving wheel to rotate the driven wheel so as to continuously convey the wire; meanwhile, the inert gas can be sent out through the second passage and the conveying mechanism to prevent a workpiece from being oxidized.

Abstract: A disclosed interactive gaming apparatus may include a flexible mat structure. The flexible mat structure may have at least one sensor module placed therein. The gaming apparatus may also include a main body having a computation module with gaming software installed therein. When the human operator motions, the sensor module may detect such motions along with data arising out of contact by the human operator on the flexible mat structure and deliver the same to the computation module. The computation module may compute the detected and enable a projector module to project an output image upon a surface of the flexible mat structure.
