  • Publication number: 20240048500
    Abstract: An Internet Protocol (IP) phone system includes a traffic control device connected to a line. The traffic control device acquires a call duration of each of calls on one line shared by a plurality of IP phones, and sets a packet discard rate of each of the calls in a manner where the packet discard rate is proportional to the call duration until start of a new call so that total call traffic falls within a line capacity of the one line when the total call traffic exceeds the line capacity with the start of the new call.

  • Publication number: 20230370380
    Abstract: A congestion control method in an IP telephone system includes acquiring a number of simultaneous calls in one line shared by a plurality of IP telephones, acquiring a call time order corresponding to length of a call time for each call, and controlling a packet discard rate of each call on the basis of the number of simultaneous calls and the call time order. The packet discard rate of each call is set to a predetermined first upper limit value or less. In addition, the packet discard rate is set higher as the call time is longer, and the packet discard rate is set lower as the call time is shorter. Further, the packet discard rate of the latest call having the shortest call time is set to be equal to or less than a predetermined second upper limit value lower than the predetermined first upper limit value.

  • Publication number: 20230318632
    Abstract: Provided is a software wireless device capable of continuing communication without being affected by quality deterioration of a wireless line and without discarding of traffic data. The data to be transmitted is duplicated and wirelessly transmitted over a plurality of communication lines having different frequency bands (step 104). The received data received by the communication line having the best line quality is validated. Another frequency band that is different from the frequency band used in the plurality of communication lines and can provide line quality exceeding a determination criteria is searched (step 106). When the quality of the communication line communicating the same data deteriorates (step 108), the communication on that line is switched to the wireless communication on the additional communication line using the other frequency band (step 110).

  • Publication number: 20230300255
    Abstract: A congestion control method in an IP telephone system includes processing of acquiring the number of simultaneous calls on one line shared by a plurality of IP telephones, processing of acquiring lengths of call duration of respective calls, and communication parameter setting processing of setting communication parameters that contribute to communication quality of respective calls on the basis of the number of simultaneous calls and the call duration. The call duration of the first call is longer than the call duration of the second call. The communication parameter setting processing includes processing of setting communication parameters such that the communication quality of the first call is worse than the communication quality of the second call in a case where the number of simultaneous calls exceeds a threshold value.

  • Publication number: 20230275839
    Abstract: To avoid uniform deterioration of the voice quality of all the calls sharing an IP phone line at a time of congestion. The congestion control method in an IP phone system includes a call state acquisition process of acquiring the number of simultaneous call sessions in one line shared by a plurality of IP phones. A congestion control method further includes a packet loss control process of setting a priority ranking to each call session and dynamically controlling packet loss rates of the call sessions in accordance with the number of the simultaneous call sessions and the priority ranking. In the packet loss control process, the packet loss rate is set lower for call sessions ranked higher in priority, and higher for call sessions ranked lower in priority.

  • Publication number: 20230217281
    Abstract: A wireless quality degradation factor detection method according to an embodiment includes a spectrum generation step of generating a spectrum based on a received radio wave, a determination step of determining whether or not information based on the generated spectrum contains a factor that prevents maintenance of the quality of the received radio wave based on a determination criterion specified in advance, an identification step of identifying the factor that prevents maintenance of the quality of the received radio waves based on the result of the determination and the determination criterion, and an output step of outputting information representing the identified factor.

  • Patent number: 5221340
    Abstract: In a method for producing an odor-free metallic pigment composition, a metallic pigment is ground by a wet process. The pigment is then mixed into a molten thermoplastic resin to vaporize any additives in the metallic pigment by the heat of the resin. The pigment may be dried until its solid content becomes 50-99 percent by weight before mixing into the molten thermoplastic resin.

  • Patent number: 4868033
    Abstract: Laminates comprising a film of heat-shrinkable synthetic resin and a metallic foil or metallized plastic film laminated to the resin film through a bonding layer which comprises a discontinuous layer of a synthetic resin which flows at a temperature for heat shrinkage and an adhesive layer which maintains its adhesive strength at that temperature. Upon heat shrinkage, the metallic foil or metallized plastic film will wrinkle at the portions in contact with the synthetic resin which is not highly adhesive at the temperature for heat shrinkage. The heat-shrunk laminate can be formed into a casing or container such as an electromagnetic interference shield, a packaging material, and decorative material.

  • Patent number: 4848931
    Abstract: A packaging sheet for containing foodstuff is proposed which comprises a substrate of synthetic resin and a metallic film layer laminated to the substrate through an adhesive layer and a resin layer having a lower bond strength than the adhesive layer. Food packaging containers using the packaging sheet as a lid and self-standing pouches using the packaging sheet as their side sheets are also proposed. Before such a container or pouch containing food is put into a microwave oven for cooking, the metallic film layer or layers can be removed easily from the substrate.

  • Patent number: 4771937
    Abstract: An improved lid for heat-sealing a container is proposed which comprises a substrate and an outer peel layer laminated to the substrate through two adhesive layers, one of which has a weaker adhesion strength than the other. The substrate has a base sheet and is formed with such a discontinuous cut outlining an opening that a tear starting from the end of one cut will be received by the front end of a cut next to the cut, and a partial opening will be formed in the substrate.
