  • Patent number: 10886897
    Abstract: A filter device includes a substrate and first to third filters provided on the substrate and each including an input terminal and an output terminal. A center frequency of a pass band of the first filter is lower than a center frequency of a pass band of the second filter, and the center frequency of the pass band of the second filter is lower than a center frequency of a pass band of the third filter. Of the first and third filters, when the filter having the center frequency of the pass band close to the center frequency of the filter is defined as a proximity filter and the other is defined as a non-proximity filter, an input terminal and an output terminal of the proximity filter are not adjacent to an input terminal and an output terminal of the second filter.

  • Patent number: 10880043
    Abstract: Methods and computer systems for establishing an interactive consistency property between receivers of messages. Messages are transmitted to receivers by a sender over a communication network including disjoint communication paths for connecting receivers and sender. Switches include local clocks. Local clocks of non-faulty switches are synchronized to each other with a maximum error (precision), and receivers detect switch failures. Redundant copies of a message are forwarded by sender to each receiver across different disjoint communication paths. A switch of each disjoint path is configured such that redundant copies are forwarded to each receiver with a temporal distance between disjoint paths. That distance is selected such that all non-faulty receivers receive redundant copies in the same receive order, when the switches and communication links of the disjoint paths exhibit no failure.

    Abstract: The first buffers forward data from the first device to the respective corresponding second devices through the respective buses while the second buffers forward data from the respective corresponding second devices to the first device through the respective buses. In response to a simultaneous data transmission request to simultaneously transmit data from the first device to the second devices, the switch controller switches the first buffer into a data-forwarding enable state, and switches the second buffer into a data-forwarding disable state, for simultaneous data transmission from the first device to the plurality of the second devices. The pseudo-response generator generates pseudo-response signals acting as a plurality of response signals that the second devices transmit to the first device as a result of the simultaneous data transmission, and transmits the plurality of the pseudo-response signals to the first device. This configuration achieves simultaneous access to multiple devices.

  • Patent number: 9843590
    Abstract: A method and apparatus for causing a delay in processing requests for Internet resources received from client devices is described. A server receives from a client device a request for a resource. The server transmits a response to the first client device indicating that access to the resource is temporarily denied. The response includes a cryptographic token associated with the first request and a predetermined period of time during which the first client device is to wait prior to transmitting another request to access the resource. The server receives a second request for the resource, upon determining that the second request includes a valid cryptographic token, the server causes the second request to be processed. The server receives a third request for the resource, and upon determining that the third request does not include a valid cryptographic token, the server blocks the third request.

  • Patent number: 9832679
    Abstract: A window regulator for improving the performance of communications networks is described. In a communications network, data is sent downstream from a sender to a receiver, and acknowledgements are sent back upstream. When data is received at the receiver, the data is placed in a buffer and an acknowledgement of receipt may be sent. If no acknowledgement is received by a sender after a certain period of time, the sender retransmits the data. The receiver communicates how much data the receiver is willing to receive at any given time by sending an advertised window to the sender. The window regulator sets the size of the advertised window based on measurements of capacity in the network to improve the amount and rate of data sent downstream while avoiding loss of data and subsequent retransmissions.
