Abstract: A composite structure includes an electronic component and a supporting member. The electronic component includes a main body and a plurality of pins extended outwardly from the main body. The supporting member includes a first supporting part and a second supporting part. The first supporting part is foldable with respect to the second supporting part. The main body of the electronic component is accommodated within the first supporting part of the supporting member. The pins are accommodated with the second supporting part of the supporting member. The first supporting part is folded with respect to the second supporting part such that the pins are bent to define a bent structure.

Abstract: The present invention provides an electronic device having a rotatable plug. The electronic device includes a casing having a hollow portion, a rotary base rotatably mounted within the casing, and a circuit board mounted within the casing. The rotary base includes a rotating disc and a plug. The plug includes conducting pins. The conducting pins are coupled with the rotating disc such that respective first ends of the conducting pins are exposed and protruded through the hollow portion of the casing and respective second ends of the conducting pins are protruded from bilateral sides of the rotating disc. The circuit board includes a first conductive element and a second conductive element corresponding to the first and second conducting pins. The first conducting pin and the second conducting pin are electrically connected to the circuit board when the rotary base is rotated to a specified position.

Abstract: A cushioning member for use in a circuit board includes an elastic main body and a fixing element. The fixing element is coupled with the elastic main body and aligned with a perforation of the circuit board. The fixing element includes an extension part and a fastening part. The extension part is arranged between the elastic main body and the fastening part. The fastening part is arranged on an end of the fixing element. The fastening part is sustained against a first surface of the circuit board and the extension part is received in the perforation after the fixing element is penetrated through the perforation, so that the cushioning member is combined with the circuit board and the elastic main body is attached on a second surface of the circuit board, wherein a cushioning efficacy is provided when the electronic device is suffered from an external force.

Abstract: A packing box includes a plurality of cushioning members, a plurality of carrier members and a cover member. Each of the cushioning members includes multiple length-wise retaining plates and multiple width-wise retaining plates arranged in a staggered form to define a plurality of receiving portions for receiving the articles therein. The carrier members are arranged in a stack form and having respective confining spaces for confining the cushioning members in position. The cover member shelters the cushioning members, the carrier members and the articles.

Abstract: An electronic device includes a casing, a plug, a retaining element and a resilient element. The casing has multiple support members and multiple receiving parts. The plug has a rotating shaft and multiple pins. The rotating shaft includes a ratchet tenon and is pivotally supported on the support members. The pins are substantially perpendicular to the casing when the pins are rotated to the first position. The pins are received in the receiving parts of the casing when the pins are rotated to the second position. The retaining element includes a ratchet part. The resilient element is contacted with or sustained against the retaining element for providing a restoring force on the retaining element. The ratchet part is engaged with the ratchet tenon of the rotating shaft due to the restoring force, so that the pins are automatically fixed in either the first position or the second position.

Abstract: A boomerang includes a central disk comprised of concentric inner and outer rings that are connected by radially extending connection sections. Wings radially extend from an outer circumference of the outer ring, corresponding in position to the connection sections. The inner ring defines a central bore. Arc openings are formed between the inner and outer rings and delimited by the connection sections. Aligned openings are defined in each wing and the associated connection section. Tabs extend from edges of the openings in opposite directions and also incline in opposite directions. Further tabs are formed on and extend from an inner circumference of the outer ring. When the boomerang flies, the central bore, the arc openings, and other openings allow airflow to pass therethrough, while the tabs impose constraints to the airflow to induce stable and extended flying of the boomerang in the air.
