  • Patent number: 7017964
    Abstract: A chopstick manipulating device includes a resilient connecting member having a pair of inwardly angled side members and a bottom portion extending therebetween to form a triangular member with an open top. A pair of chopstick keepers have coplanar substantially triangular-shaped board portions disposed on the rear of board member and outwardly extending posts disposed on an outer corner of the substantially triangular-shaped board portions. Elastic boards extend outwardly from a top portion of the board members. A back surface of each of the board members of the chopstick keepers is coupled to an outer surface of a respective side member of the resilient connecting member. The respective board member, post and elastic board define an open channel for releasably and slidably securing a chopstick against the triangular-shaped board portion. The chopsticks pivot as the resilient connecting member is opened and closed.

  • Publication number: 20020159267
    Abstract: The invention is a touch-sensitive switch with brightness-control for lamps. The switch consists of a switch body and a switch shell. The switch body comprises a brightness-control and touch-sensitive board, a brightness-controlling circuit and a luminous device. A touch-sensitive conductive thin film is on an outer surface of the brightness-control and touch-sensitive board. The luminous device is beneath the brightness-control and touch-sensitive board. Input of the luminous device is connected to output of the brightness-controlling circuit. There are electrode leading wires on the brightness-control and touch-sensitive board, which are serially connected to the brightness-controlling circuit. The switch of the invention is convenient to use and easier to manufacture. It can be used to control the brightness of one or multiple lamps and to function as a position indicator and light for gloomy or dim environments.
