  • Patent number: 6434226
    Abstract: In order to realize notification of an incoming call at a client terminal utilizing an existing extension switch system, an exchange of the extension switch system is linked with a server of client terminals such that notification of an incoming call to an extension is made also at a client terminal. Further, whether an incoming call to a client terminal is permitted or not can be changed depending on whether the client terminal is in a log-in state or not. Still further, notification of an incoming call to a client terminal is made by reproducing an audio file or the like to realize a flexible extension call. Further, a response to an incoming call at a client terminal is managed by a timer such that, in case of time out, an ordinary extension rings. Still further, the server is made to have alternative recipient information such that notification of an incoming call is transferred via the server.

  • Patent number: 6353856
    Abstract: A terminal (A) sends a call request message to a terminal (b). This message contains a request for a TCP/IP service. A call control section in a switching node passes the message to an agent, which, in turn, examines whether or not an IP address and a TCP port number set in the received call request message have been entered into a firewall table. If they are found, the request for access to the terminal (b) is granted. As a result, an ATM connection is set up between the terminal (A) and the terminal (b) and a TCP/IP connection is set up on the ATM connection. If they are not found, access to the terminal (b) is refused and no ATM connection is set up between the terminal (A) and the terminal (b).

  • Patent number: 6351469
    Abstract: A TDMA in a CATV center and a CAU in a subscriber home communicate a B-ch idle/busy map indicating the idle/busy state of a B channel in synchronization with each other, so that the allocation of the B channel dedicated to sound and the C channel dedicated to data in a transmission frame can be dynamically changed according to the contents of the B-ch idle/busy map. Consequently, it becomes possible to effectively use a transmission bandwidth up to its maximum.

  • Patent number: 6338238
    Abstract: A jewelry chain is formed from a plurality of coil links, with each link having a coil diameter, a first end and a second end. With the exception of the ends of the chain, which are typically secured to the mating clasp sections, each of the links in at least a portion of the body section are intertwined with two or more links. The number of coils capable of being intertwined is predominantly governed by the coil diameter and the number of turns in each coil.

  • Patent number: 6330222
    Abstract: A traffic control apparatus in an exchange, comprised of an incoming cell analyzing means for identifying if incoming cells are fixed band cells or variable band cells, separating the two, and calculating the total fixed band cell flow and the total variable band cell flow, an incoming cell amount decision means for instructing the allocation of the amount of cells to be discarded among subscribers of the variable band service by a predetermined ratio when the sum total cell flow, that is, the sum of the calculated total fixed band cell flow and total variable band cell flow, exceeds an allowable cell flow, and an incoming cell limiting means for discarding cells from among the incoming variable band cells in accordance with the instruction. Due to this, when subscribers using the variable band (e.g., UBR) service through an exchange use the exchange with a greater working band width than the allowable band width, the discarding of cells is fairly apportioned out among the subscribers.

  • Patent number: 6320852
    Abstract: A technique used in a mobile communications system. A mobile terminal station transmits a signal subjected to an error-correction encoding processing. Each of a plurality of base stations receives the signal transmitted from the mobile terminal station via the wireless line, performs an error-correction decoding processing for the received signal, and transmits an error-correction decoded signal to a base-station host apparatus via the wired line. The base-station host apparatus performs an error-correction encoding processing for each of the signals received from the base stations, composes the thus error-correction encoded signals into one signal, and performs an error-correction decoding processing for the composed signal. The technique can improve the error rate of a received signal without increasing the amount of signal data flowing between the base stations and the base-station host apparatus.

  • Patent number: 6317605
    Abstract: A mobile communication terminal includes a location information database storing location data and map data for each of the radio cell stations. When receiving a data request including an identification of a second mobile terminal from a first mobile terminal through a first radio cell station, the database is searched for first location data of the first radio cell station, second location data of a second radio cell station forming a micro cell in which the second mobile terminal is located, and map data for at least one of the first and second radio cell stations. Then the first and second location data and retrieved map data are transferred to the first mobile terminal through the first radio cell station and thereby a map and two locations corresponding to the first and second mobile terminals are displayed on screen based on the retrieved map data and the first and second location data.

  • Patent number: 6313982
    Abstract: Disclosed is a protective case for protecting a portable electronic device against moisture and dust so that the device can be carried anywhere. The protective case has an upper case and a lower case which, by being abutted against each other, form a closed space in a interior of which the portable electronic device (100) is capable of being accommodated. Provided in at least one of the cases is a through-hole at a position opposing an operating element of the portable electronic device accommodated inside the space. The through-hole is closed by a closure member (167) comprising an elastic material and having a push-button (165) that is capable of pushing the operating element of the portable electronic device from the outside. Furthermore, the abutting portion of each case is sealed by a sealing member comprising an elastic material, whereby moisture and dust are positively prevented from penetrating the interior.

  • Patent number: 6314144
    Abstract: A digital wireless receiving apparatus performs AGC control. A desired wave level is detected at a modulator, and AGC control is performed for a high frequency portion by detecting a desired wave level at a demodulator. A tap number of a digital filter in the demodulator is controlled or another analog filter of an intermediate frequency detects an input level of an interfering wave or a desired wave, thereby performing AGC control for the high frequency portion and controlling the tap number of the digital filter at the demodulator.

  • Patent number: 6313832
    Abstract: There is provided a remaining battery capacity display device for use in a communication device powered by a battery, which is capable of displaying an exact remaining battery capacity even if battery current consumption varies. A voltage detection device detects a value of voltage of the battery to deliver the detected voltage value to a remaining battery capacity calculation device within a controller, while a current consumption calculation device calculates a battery current consumption based on a transmission output level of a transmission/reception block to deliver the calculated battery current consumption to the remaining battery capacity calculation device. The remaining battery capacity calculation device calculates a remaining battery capacity based on the received values of the battery voltage and battery current consumption.
