Abstract: The present invention provides an earphone storage structure comprising a necklace, two fasteners formed in the two ends of the necklace respectively and a stopper formed in the necklace. The size of the fasteners is less than the size of the stopper and the size of the earphones. Therefore, the earphone may couple with the necklace with the fasteners fastening the earphones. Moreover, the stopper and the fasteners may together determine the extendable distance of the earphones.

Abstract: A dual-axis circuit board is disclosed. The circuit board includes at least an upper circuit board, a lower circuit board, and a connecting circuit board. The upper circuit board connects to the circuit in a top cover of the folding electronic apparatus, and the lower circuit board connects to the circuit in the body of the folding electronic apparatus. The angle between the folding directions of the upper and lower circuit board is approximately 90 degrees.

Abstract: A handheld electronic device (200) is provided. The handheld electronic device mainly comprises a first casing (210) and a second casing (220). A display screen (212) and an image-capturing apparatus (222) are set up on the first casing and the second casing respectively. The display screen is positioned on a front surface (210a) of the first casing. The second casing is pivoted to a rear surface (210b) of the first casing and the second casing is permitted to flip between first and second positions. At the first position, the second casing is received in a recess defined in the rear surface of the first casing, and the image-capturing apparatus faces rearwards. At the second position, the second casing is located above the first casing, and the image-capturing apparatus faces forwardly.

Abstract: A handheld electronic device has a body (110) and a sliding member (120) wherein the body is pivotably mounted on the sliding member by a pivot axle (102). The body is provided with a display (510) thereon, and the sliding member is provided a keyboard (520) thereon. When the sliding member is lengthwise aligned with the body, the keyboard is hidden below the body. When the sliding member is rotated relative to the body to reach a position wherein the sliding member is at an orientation perpendicular to that of the body, the keyboard is exposed and has two end portions located outside of lateral sides of the body, respectively.

Abstract: An image data transfer device for use with a portable non-volatile memory card and an optical disc includes a memory card socket for attaching thereto the portable non-volatile memory card; a digital image processor electrically connected to the portable non-volatile memory card which has been attached to the memory card socket, reading a digital image data from the portable non-volatile memory card, and transforming the digital image data into an interactive image file; and a recording device electrically connected to the digital image processor for writing the interactive image file into the optical disc which has been placed into the recording device.

Abstract: A self-returning aerial glider is disclosed, which can be launched to travel outwardly away from the point of launching and subsequently reverse its flight and return to the location of launching. The object is comprised of a generally ring-shape planar body conforming to specific dimensional proportions and mass-to-projected-area ratios optimized to producing favorable return glide behaviors.
