Abstract: A soft-switching power converter includes a main switch, an energy-releasing switch, and an inductive coupled unit. The main switch is a controllable switch. The energy-releasing switch is coupled to the main switch. The inductive coupled unit is coupled to the main switch and the energy-releasing switch. The inductive coupled unit includes a first inductance, a second inductance coupled to the first inductance, and an auxiliary switch unit. The auxiliary switch unit is coupled to the second inductance to form a closed loop. The main switch and the energy-releasing switch are alternately turned on and turned off. The auxiliary switch unit is controlled to start turning on before the main switch is turned on so as to provide at least one current path.

Abstract: Interconnect structure packages (e.g., through silicon vias (TSV) packages, through interlayer via (TIV) packages) may be pre-manufactured as opposed to forming TIVs directly on a carrier substrate during a manufacturing process for a semiconductor die package at backend packaging facility. The interconnect structure packages may be placed onto a carrier substrate during manufacturing of a semiconductor device package, and a semiconductor die package may be placed on the carrier substrate adjacent to the interconnect structure packages. A molding compound layer may be formed around and in between the interconnect structure packages and the semiconductor die package.

Abstract: A quick release coupling includes male and female connector assemblies releasably secured together. The male connector assembly includes two parallel male connectors and the female connector assembly includes two parallel female connectors. A sleeve assembly is releasably connected to one ends of the female connectors. A plunger assembly is provided in each of the sleeve assembly and female connector. A sleeving assembly is provided on each of the female connector and the sleeve assembly. The parallel female connectors can be disconnected from the parallel male connectors or connected together at the same time. After the female connectors have disengaged from the male connectors, leakproof arrangements in the female connector assembly act to prevent water in the female connector assembly from leaking.

Abstract: A latch coupling includes male and female connector assemblies releasably secured together. The male connector assembly includes two parallel male connectors and first latches. The female connector assembly includes two parallel female connectors and second latches. A sleeve is releasably connected to an end of the female connector. Force is exerted on the second latches to hook the first latches so as to connect the female and male connector assemblies together. The parallel female connectors can be disconnected from the parallel male connectors or connected together at the same time. After the female connectors have disengaged from the male connectors, leakproof arrangements in the female connector assembly act to prevent water in the female connector assembly from leaking.

Abstract: A lens structure for mobile phone flashlight is provided, to improve luminance of edge area and overall luminance. The lens structure includes a lens body. The lens body includes an incident surface and a light-emitting surface, and the incident surface is a Fresnel lens. Edge area of the light-emitting surface is partially disposed symmetrically with at least a pair of second surfaces, and remaining area forms a first surface. The edges of the second surfaces tilt towards direction of the incident surface so that the first surface forms an angle with the second surfaces. As such, the lens structure is able to refract light to project in near rectangular area onto a target object when taking picture.

Abstract: A shoe structure is composed of a vamp, an insole and an outsole. The insole and its balanced plate are made of a botanic cornstarch synthetic resin. A support plate made of a bamboo sheet in different styles is disposed between the insole and the outsole, so that the integrated shoe structure can absorb forces exerted onto a foot sole to reduce the force and achieve a shock absorption effect and an anti-shock effect by the elasticity of fibers distributed on the support plate, so as to reduce the burden of the foot sole without feeling an increased weight, and the shoe structure made of a botanic material gives the effects of using an easily available material, lowering cost, and protecting environment.

Abstract: A stocking capable of the convenient holding of articles, wherein the stocking body section extending upward from the sole and along the joint between the calf and the thigh has an additional layer appended to the stocking body in the form of an annular, wrap-around outer layer stocking body. The outer layer stocking body bottom consists of a fixing means disposed at the upper extent of the joint over the sole and an opening at the topmost end that is hemmed. As such, after being worn by the user, articles such as protective equipment and warmth insulating material are directly placed inside the outer layer stocking body and retained in position by the knitted binding force of the outer layer stocking body, thereby enabling effective leg section protection and convenient wearing utility.
