Abstract: Disclosed are a rocker device and a handle controller. The rocker device includes a mounting seat assembly, an electric control board, an upper shell and a bottom shell. The mounting seat assembly is provided with a first groove and an arc-shaped groove for mounting the rocker arm assembly. The electric control board is disposed in the first groove, and the upper shell covers a top area of the mounting seat assembly. The upper shell fixes two ends of the rocker arm assembly in the arc-shaped groove and confines the electric control board to the first groove. A first connecting portion is also provided on an outer periphery of the upper shell. The mounting seat assembly is disposed in the bottom shell, and the bottom shell is clamped with the first connecting portion.

Abstract: A joystick device is provided. The joystick device includes a housing, a joystick assembly, a reset assembly, a translation assembly, and a circuit board. A magnetic component is located on the translation assembly, and a magnetic induction element is located on the circuit board. The joystick assembly pushes the translation assembly to translate, and the magnetic induction element generate an output that changes with the movement of the translation assembly. A handle using the joystick device also provided.

Abstract: A synchronous joystick sensor is provided, the synchronous joystick sensor includes a joystick, a joystick arm assembly, a swing detection assembly, a reset assembly. The joystick arm assembly is sleeved on the joystick, the arm assembly is driven by the joystick to swing in a first direction and a second direction perpendicular to the first direction. The swing detection assembly is configured to swing detection assembly, and configured to measure the swing amount in the first direction and the second direction through a magnetic detecting element, and convert the swing amount into a first electronic signal and a second electronic signal; a reset assembly configured to make the joystick being in a vertical reset state when there is no external force.

Abstract: A wick for use in a burning appliance consisting of (A) a fuel absorbing section composed of a plurality of short fiber web layers forming its outermost layers and one or a plurality of long fiber layers of numerous long fibers aligned substantially in one direction and (B) a heat-resistant burning section adjacent to the fuel absorbing section. The long fiber layers and the short fiber web layers are physically united into an inseparable integral structure by, for example, needle-punching or stitch-bonding. The wick has a high rate of fuel absorption and permits burning of a fuel at a high caloric output.
