  • Patent number: 11020213
    Abstract: An intraluminal device adapted to be positioned in a lumen that experiences peristalsis and method of fixation of an intraluminal device in the lumen, includes a wall configured to the size and shape of a portion of the lumen and at least one core. The at least one core is removably connected with a portion of the device wall. The at least one core is configured to be positioned against the lumen when the wall is positioned in the lumen. In this manner tissue envelopes the core during implantation of the intraluminal device. The at least one core is configured to be axially removable in situ from the tissue enveloping the core after the device has been deployed by disconnecting the core from the portion of the wall in order to explant the intraluminal device from lumen.

  • Patent number: 9674104
    Abstract: An example method for adapting Proportional Integral controller Enhanced (PIE) algorithm for varying network conditions is provided and includes estimating an average dequeue rate at which packets are dequeued from a queue of packets maintained in a buffer in a network element operating, estimating a current queuing latency for the queue of packets based on the average dequeue rate, determining a target delay based on the average dequeue rate, the target delay varying with the average dequeue rate according to a predetermined relationship, and calculating a current drop probability associated with a probability that packets arriving at the buffer will be dropped or marked, the current drop probability being calculated using at least the current queuing latency and the target delay. In some embodiments, a threshold for a number of bytes dequeued from the buffer is estimated based on network conditions.

  • Patent number: 8156554
    Abstract: A method and system for verifying identification of an electronic mail message. An electronic mail message including a signature and a key is received, the signature identifying a domain from which the electronic mail message originated and the key for verifying the signature. A key registration server of the domain is accessed to verify the key. The key registration server provides for verifying that a key used to sign an electronic mail message is valid and that the sender is authorized by the domain to send the electronic mail message from the return address.

  • Patent number: 7650387
    Abstract: A method, a system, a machine-readable medium, and an apparatus for managing storage on a shared storage space, for example, on an email server, are provided. A plurality of emails is compared. If the content of each of the plurality of emails is the same, then a single copy is stored on the email server. Further, each recipient of the plurality of emails is enabled access to the stored email via a link to the single copy. Additionally, one or more attachments of the plurality of emails are compared. If an attachment is the same in each of the plurality of emails, then it is stored as a single copy. Further, a link is inserted in each of the plurality of emails, enabling access to the attachment from the single copy.

  • Patent number: 4809265
    Abstract: A controller for a bridge interconnecting local area networks operates in two modes. In a first mode the controller receives and transmits station data frames with previously appended frame check sums. In a second mode the controller responds to requests for information from stations by generating data frames from an associated memory. The controller computes and appends frame check sums and then transmits the frames and check sums to the requesting station. The controller is constructed and is effective to operate in a way which insures that all station data frames transmitted from stations to the bridge are received by the bridge without interruption or loss during all periods of operation. The controller receives all such frames at all times, including the time intervals during which circuitry in the controller must be off line and reprogrammed for changing operation between the first and second modes.

  • Patent number: 4706081
    Abstract: A communications system interconnects local Area Networks (LAN's) across broadcast simplex channels. The LAN's are connected independently and transparently of protocols above the data link layer so that the system appears to the user at a station in one Local Area Network as one large single network. A bridge interconnects the LAN's across simplex channels. The bridge is constructed to permit more than two local area networks to be interconnected across simplex channels to the bridge and to provide communication between stations.
