Abstract: A movement detection method, applied to a navigation input device with a navigation pattern comprising a center pattern and a radial pattern. The movement detection method comprises: (a)capturing a sensing image comprising a center pattern image and at least portion of a radial pattern image by an image sensor, wherein the center pattern image corresponds to the center pattern and the radial pattern image corresponding to the radial pattern; (b)computing a translation of the navigation input device according to shift of the center pattern image; and (c)computing a rotation angle of the navigation input device according to a first pattern relation between the center pattern image and a first portion of the radial pattern image. The translation and the rotation angle can be precisely and sensitively detected even if the joystick device is miniaturized, since the translation and the rotation angle are computed according to the navigation pattern.

Abstract: A fluid mixing device includes a body, a water controlling valve assembly and a Venturi tube structure. The body is internally formed with inlet channels for communicating with water source, a first channel, an outlet channel communicating between the first channel and outside of the body, and a gassing channel communicating between the first channel and a gas source. The water controlling valve is operable between first and second positions. The Venturi tube structure is disposed within the first channel and includes a necked passage communicating with the first channel and a gassing hole communicating between the necked passage and the gassing channel. When the water controlling valve is located in the first position, the water flow passes through the necked passage and draws gas from the gas source through the gassing hole to come into the necked passage to mix with each other.

Abstract: A gas injection device is provided. A separation plate is disposed between inlet and outlet ends of a main body. At least one flow hole is disposed around a through hole of the separation plate. Top, middle and bottom sections of a valve body are disposed respectively at the inlet end, through the through hole and at the outlet end. Respective outer diameters of the top and bottom sections are larger than an inner diameter of the through hole, and the largest outer diameter of the bottom section is larger than a smallest inner diameter of the outlet end. A length of the middle section is longer than an axial length of the through hole. An elastic member through the middle section abuts against the separation plate and the bottom section to bias the valve body toward the outlet end and normally unclose the bottom section.
