Abstract: A venting device includes a first flap, which is configured to be actuated to swing upward during a rising time, and a second flap, which is disposed opposite to the first flap and configured to be actuated to swing downward during a falling time, a first actuating portion disposed on the first flap, and a second actuating portion disposed on the second flap. The venting device configured to form a vent is disposed within a wearable sound device or to be disposed within the wearable sound device. The vent is formed via applying a first voltage to the first actuating portion and applying a second voltage on the second actuating portion, such that the venting device gradually forms the vent.

Abstract: A method of reducing gray energy consumption and achieving optimal gray energy saving for carbon neutralization is proposed. In a cellular network, each cell or BS (group of cells) has renewable (green) and non-renewable (gray, on-grid power) energy sources. The renewable (green) energy is highly variable and unpredictable, while non-renewable (gray, on-grid power) is stable but is not renewable and thus has more carbon impact. Each cell or BS (group of cells) services is associated UEs when it is on. In one novel aspect, a cell or BS (group of cells) that consumes more non-renewable energy can give some or all of its served UEs to another cell or BS (group of cells) that consumes less non-renewable energy.

Abstract: A backlight module of a display device includes a back plate, a light source, a reflector, a support pin, a diffuser, and an optical film. The light source is disposed on the back plate. The reflector is disposed on the back plate and has an opening. The support pin is located in the opening and on the back plate. The support pin includes a base, an abutting portion, and a transparent supporting portion. The transparent supporting portion is on the base. The abutting portion protrudes outward from the base and extends onto the reflector. The abutting portion and the base form a step structure. The diffuser is located on the transparent supporting portion. The optical film is located on the diffuser. The reflector is located between the abutting portion of the support pin and the back plate.

Abstract: A wearable display device comprises a casing, a display panel, a lens and a prism. The display panel is disposed on the casing, and has two planes connected to each other. An angle between the planes is greater than 0 degrees and less than 180 degrees. The lens is disposed on the casing, and faces the planes. The prism is disposed between the display panel and the lens, and comprises two refractive portions. Each refractive portion has a light-incoming surface and a light-outgoing surface. The light-incoming surfaces respectively face the planes of the display panel. The light-outgoing surfaces face the lens. An angle between the light-outgoing surfaces is greater than 0 degrees and less than 180 degrees. One of the light-incoming surfaces is parallel to one of the planes of the display panel. The other light-incoming surface is parallel to the other plane of the display panel.

Abstract: A dye compound is described, which is expressed by formula (I): wherein A1, A2 and A3 each independently represent a substituted or unsubstituted 1,4-phenylene or 2,5-thiophene group, and B1 and B2 each independently represent a substituted or unsubstituted aryl group. The dye compound is suitably used as a dye sensitizer in a dye sensitized solar cell (DSSC).

Abstract: A foldable wheelchair includes a pair of front legs, a pair of rear legs, a seat frame, a dual-hinge joint, and a pair of armrests. A front pivoting means is pivotally connected to the seat frame and the front legs. A rear pivoting means is pivotally connected to the seat frame and the rear legs. A bottom of the dual-hinge joint is pivotally connected to a rear of the seat frame. A top of the dual-hinge joint is pivotally connected to a backrest body. Therefore, the front legs can be folded backward by the front pivoting means and the rear legs can be folded forward by the rear pivoting means. The tilt angle of the backrest body can be adjusted and the backrest body can be folded forward. Thereby the volume of the wheelchair can be reduced.
