  • Patent number: 6885347
    Abstract: A method for assembling a PIFA antenna (20) onto a plastic base of a handle electronic device includes forming the plastic base (30) with a number of posts (35) by a single-shot-molding process and punching a number of pinholes (215) on the PIFA antenna body corresponding to the posts protruding thereon. The plastic base and the antenna body are conjoined together with the posts aligned with the pinholes. Then the posts are heated and then transfigured to flat-shape for engaging the edges of the pinholes. Thus the PIFA antenna is firmly retained on the plastic base.

  • Publication number: 20040215812
    Abstract: A method for transmitting the time-critical data over Ethernet. The method can tolerate at least 50% of packet-drop without affecting the quality of transmission. Ethernet network is considered a connectionless network, so the packet-drop is not avoidable. Therefore, the key to transmitting the time-critical data over Ethernet is not to prevent the packet-drop, but to control and to tolerate the packet-drop. To tolerate the packet-drop, we have to carry redundant data in each Ethernet packet so that we can recover the lost information from the redundant data when packet-drop occurs. An easy way of carrying the redundant data is as follows. Every packet carries two parts of data. The first part is the required data, and the second part is the redundant data. The required data is the data that the packet is supposed to carry in the case without redundant data. The redundant data is the required data of the next packet.

  • Publication number: 20030152092
    Abstract: A multilevel hierarchical addressing and routing mechanism for high-speed Internet is presented. The presented mechanism enables an Internet router to make its packet forwarding decision based on a short, fixed-length block of the IP address. This short, fixed-length block can be used as an index to an entry in the routing table. This will significantly speed up the packet forwarding and routing procedure, which is crucial for the future high-speed Internet.

  • Publication number: 20030076675
    Abstract: A sunshine curtain is a closed cubicle formed by a mounting base, a front wall, a back wall, two sidewalls and a bottom. There is a light tube inside the cubicle. On the outside of the front wall, there is a drawing of a normal window picture. On the inside of the back wall, there is a drawing of a sunshine-outside picture. The part of the front wall, which is covered by the glass area of the window picture on the outside of the front wall, is made of transparent material, so that we can see the sunshine-outside picture on the inside of the back wall through the front wall as if we saw the sunshine outside through the window. When the light tube inside the sunshine curtain is on, the light will come out of the sunshine curtain through the transparent area of the front wall. It looks like the sunlight comes in the room through the window. Therefore, the sunshine effect is created even when it's cloudy outside.

  • Patent number: 6003437
    Abstract: An apparatus for making noodles includes a casing, a rolling unit mounted on the casing for flattening a mass of dough into a flat piece of dough, a cutting unit mounted on the casing for cutting the flat piece of dough into strands of noodles, a drive unit for driving operably the rolling unit and the cutting unit, a guiding unit for guiding the flat piece of dough into the cutting unit, and an adjustment unit. The rolling unit includes a cylindrical first roller and a cylindrical second roller parallel to and spaced apart from the first roller. The first and second rollers permit passage of the mass of dough therebetween. The rolling unit further includes a first shaft connected fixedly and coaxially to the first roller, and a second shaft extending axially and rotatably through the second roller. The first shaft is coupled to and is driven rotatably by the drive unit.

  • Patent number: 5955958
    Abstract: A holiday candy jar with light and sound effects having a signal sensor (10) which gets continuous signal from a signal source (12). When someone puts his/her hand into the jar trying to get a candy, the signal between the signal source and the signal sensor will be blocked. A control circuit board (20) is connected to the signal sensor (10) through wires (16). When signal is blocked, the control circuit board controls color lights (14) blinking and a speaker (20) producing a special sound for holidays.

  • Patent number: 5815490
    Abstract: A method of managing a telecommunication subnetwork system composed of a number of network elements coupled together through an optical medium to form a Synchronous Digital Hierarchy (SDH) network ring. Each of the network elements receives upon initiation or reconfiguration and then stores an identical ring table or knowledge database that is composed of data in a predetermined format and structure. The ring table defines the ring type and ring identification, number of nodes, ring status, node identification, sequence, and status, and provides ring provisioning tables and embedded SDH ring path identification/status information. The ring table is utilized in each of the network elements for provisioning and other management type functions common within a SDH ring environment.
