Abstract: A chip package including a substrate having an upper surface, a lower surface, and a sidewall surface that is at the edge of the substrate is provided. The substrate includes a sensor device therein and adjacent to the upper surface thereof. The chip package further includes light-shielding layer disposed over the sidewall surface of the substrate and extends along the edge of the substrate to surround the sensor device. The chip package further includes a cover plate disposed over the upper surface of the substrate and a spacer layer disposed between the substrate and the cover plate. A method of forming the chip package is also provided.

Abstract: A rotating inflatable device includes a base having an outlet a top thereof and an inlet in a side of the base. A blower is received in the base and driven by a motor. A drive part is received in the base and includes a rotating rod which is driven by another motor via a speed reduction unit. A drum to which a lower opening is mounted includes an annular ring and a central part which is located at a center of the drum by a plurality of ribs connected between the annular ring and the central part. A top end of the rotating rod is co-axially connected to the central part. A central shaft composed of a plurality of sections has its a lower end connected to the central part. A top end of the central shaft extends through a top opening of the balloon and is connected to a plate which seals on the top opening of the balloon.

Abstract: A blower includes a casing for receiving a motor therein and the shaft of the motor extends through an opening in a top surface of the casing. A blade assembly is connected to the shaft and a cover is fixedly connected to the top surface of the casing and has an air outlet. The blade assembly is enclosed by the cover. Two recesses are defined in an outer periphery of the casing and a handle is connected to one of the two recesses, and an air inlet is defined in an inside of the other recess of the casing.
