  • Publication number: 20040006595
    Abstract: The present invention enables an inter-network to provide enhanced conferencing services (such as, for example, multiple discussions, whispering and filtering) which includes one or more conference networks coupled to a service provider network over a public Internet, where the service provider network includes control features for establishing conferencing sessions. In particular, the present invention provides a conferencing (audio and/or video and/or the like networked conferencing with control features supportive of sub-conferencing) technology that incorporates enhanced control features (multiple discussions, whispering and filtering and the like) in an Internet-based solution by extending the traditional concept of “room” to “table” and “avatar” to organize a conferencing session.

  • Patent number: 6434156
    Abstract: An apparatus comprising a first interface capable of sponsoring a first protocol, a first service translation layer converting data formatted in the first protocol into streams, the first service translation layer extracting and appending a first path identifier to the streams, a core responsive to the first service translator for obtaining the streams and determining a second path identifier therefrom, the core transferring the streams according to the second path identifier, a second service translation layer accepting the transferred streams, the second service translation layer converting the transferred streams into data formatted according to a second protocol, and a second interface for asserting the data formatted into the second protocol.

  • Patent number: 6297722
    Abstract: A process for manufacturing surface mountable electrical devices includes the steps of preparing a PTC resistive plate, covering the plate with first and second conductive layers to form a laminate, forming a plurality of spaced apart bores of cross-shaped cross-section in the laminate along intersecting cutting lines at locations where the cutting lines intersect, electroplating the first and second conductive layers and the cross-shaped bores, and cutting the laminate along the cutting lines to form a plurality of polygonal elements with each of the bores being divided into four parts, each having a substantially L-shaped cross-section.

  • Patent number: 6285275
    Abstract: A surface mountable electrical devices includes a PTC resistive element having opposite first and second surfaces and lateral faces interconnecting the first and second surfaces, spaced apart first and third electrode layers formed on the first surface, a second electrode layer formed on the second surface, and a conductive layer. Each two adjacent lateral faces defines a corner that has a terraced face. The conductive layer has a first lateral segment formed on the third electrode layer, a second lateral segment formed on the second electrode layer, and a transverse segment formed on the terraced face of one of the corners and having a terraced cross-section.

  • Patent number: 6151214
    Abstract: Disclosed is a bearing structure of a central processing unit comprises a radiating plate, a back plate, a plurality of screws and elastic elements. The radiating plate has a heat conductive portion and a plurality of sleeves. The back plate is installed below the radiating plate and has a plurality of studs. The plurality of screws are placed within the sleeves of the radiating plate, and protrudes from the bottom of the radiating plate. The plurality of elastic elements being installed between the screws and the sleeve. The radiating plate is moved by the elastic elements so that the heat conductive portion of the radiating plate presses elastically the central processing unit. Therefore, the pressure will not be too large so as to harm the central processing unit, or too small so as to cause the unfastening therebetween. As a result, during assembly, the fastening force of the screws would not be adjusted. Thus, the assembly work becomes easily and the cost is reduced.

  • Patent number: 5321274
    Abstract: An electrostatic precipitator (ESP) intermittent energization controller is included with a CPU that adaptively controls the DC power used to energize the ESP. An opacimeter is mounted to the ESP for detecting the opacity of dust particles flowing through the same. The CPU searches through a table consisting of a predetermined number of charge-pause parameter sets until one charge-pause parameter set is found to cause the difference between the detected opacity level and the preset opacity level to be within a predetermined tolerable range.
