  • Patent number: 6519812
    Abstract: A hinge structure for use in an electronic device such as a digital camera for connecting two elements and making the two elements turn against each other. A gear unit is provided, which has two gears engaging with each other and turning in opposite directions. The two gears connect respectively with the two elements. When one element is turned in one direction, through the transmission of the gear unit, another element will be driven to turn in the opposite direction, to thereby change the angle between the two elements and enhance picture taking flexibility.

  • Patent number: 6510137
    Abstract: A method and system for configuring a CDMA telecommunications system having at least one sending entity and at least one receiving entity, each entity configured to transmit data on at least one physical channel (DPDCH) via a transport channel composite (CCTrCH) of multiple transport channels. At least one entity includes a data processing module configured to determine for each transport channel a first parameter (RMi) proportional to a rate matching ratio (RFi) and a second parameter representing a maximum physical rate (Ndata) and to transform for each of the transport channels a number of symbols before rate matching (Nk) into a number of symbols after rate matching (Nk+&Dgr;Nk), where the number of symbols after rate matching (Nk+&Dgr;Nk) is obtained approximately by multiplying the number of symbols before rate matching (Nk) by the rate matching ratio (RFi).

  • Patent number: 6503770
    Abstract: A self-aligned fabrication method utilizes dielectric planarization process for fabricating ridge waveguide semiconductor lasers. The dielectric planarization process starts with depositing a thick dielectric film onto the ridge-structured semiconductor wafer surface, and then the resulting corrugated dielectric surface is polished into a flat surface in a self-terminated manner. This dielectric flat surface is able to uniformly expose its semiconductor ridge tops by an overall etch-back process.
