  • Patent number: 6898073
    Abstract: A hand-held electronic device includes a main body, a first lid and a second lid. The main boy has ends engaging pivotally with the first lid and the second lid, which also has a keyboard located thereon. The first lid and the second lid are turnable selectively to cover a usage surface that contains button keys and a screen to protect the usage surface from being damaged by impact. Only the screen is exposed to the usage surface of the main body to prevent accidental key punching while operating the main body. The second lid provides keyboard data entry to make data entry more convenient.

  • Patent number: 6755706
    Abstract: The structure of a fin shaped soft paddle comprised mainly of: a loom being a hard stick for exerting force; a fulcrum provided on one end of the loom for pivotally connecting to a fixed oarlock socket of the boat; and a fin shaped soft paddle blade made of elastic material with an end connected with the fulcrum. When in rowing to move the boat forwardly, by having the difference of softness and elasticity on various areas and the bendability of the paddle blade, the resistance of the water flow and the vector offsetting the forwarding force are reduced to the minimum, so that a user can move forward the boat with a most economic mode and with simplest and most force saving motions.
