  • Patent number: 10773045
    Abstract: An anesthesia delivery and ventilation system (ADVS) includes an expiratory section, a circulation flow system (CFS), an inspiratory section, a ventilation drive system (VDS), and an anesthesia delivery system (ADS). The expiratory section receives gases from a patient and the inspiratory section and fresh gases from a fresh gas supply system. An elastic mixing reservoir receives and mixes the gases circulated by the CFS with residual gases via a connector element. The inspiratory section connects to the expiratory section at one end and to a patient connector tube at the other end. The ADS infuses an anesthetic agent into the mixed gases in the inspiratory section. The VDS delivers the mixed gases with the anesthetic agent to the patient. The VDS and the CFS are controlled and operate independently of each other to provide positive end-expiratory pressure control and ventilation control to the patient without use of a proportional valve.

  • Patent number: 8131961
    Abstract: The present invention relates to the reliable storage of data within a distributed storage system. A method and system for storing a data unit within a distributed storage system is disclosed, wherein the distributed storage system comprises a plurality of storage elements of unspecified system reliability, a public network interconnecting the plurality of storage elements and a reliability index control unit measuring a plurality of storage element reliability indexes associated with the plurality of storage elements. The data unit is stored following the steps of receiving a request to store the data unit according to a data unit reliability index and storing replicated copies of the data unit in at least one storage element, such that the data unit reliability index is achieved.

  • Patent number: 7990885
    Abstract: Accuracy of network topology information and efficient usage of available bandwidth when broadcasting topology updates are optimized in accordance with the principles of the present invention by collecting and utilizing locally known network usage information to update the network topology information between regular updates. This information is then used in establishing paths for end user communication through the network. It is further used to determine which network topology information is to be included in a subsequent update broadcast by the node. Additionally, it is used to tune adaptively the frequency with which updates are broadcast by the node.

  • Patent number: 7787875
    Abstract: A method is provided of transmitting information from a mobile terminal in a wireless telecommunications network. The method involves sending a radio signal from a first base station to a second base station. The mobile terminal modulates the radio signal so as to include the information into the radio signal. The second base station receives the radio signal and decodes the information.

  • Patent number: 7170893
    Abstract: A communication node comprises a receiver for receiving packets and a routing device for routing the received packets to one of two output ports. For each output port, the communication node further comprises a classifier for classifying a received packet based on its traffic characteristic and storing that packet in a corresponding queue for that traffic characteristic, and a concatenated packets preparer for concatenating n received packets from each queue to form a concatenated packet to be transmitted by the associated output port, where the maximum of n is determined based on the traffic characteristic of the associated queue.

  • Patent number: 6963568
    Abstract: A method for transmitting data packets includes determining from the first header part of first data packets the original first destination address, storing the original first destination address of the first data packet in storing means, discarding the first header part, storing in storing means the first body part of the first data packet. Thereafter, a concatenated or second data packet is made that includes in the body part: a data part including the first body parts and a content information part including information about the number and position of the first body parts. Thereafter, the concatenated or second data packet is transmitted to the second destination address. Hereby an increase of the payload is achieved and therefore more effective use of network connections bandwidth. A method to receive a concatenated or second data packet, devices to perform these methods and a computer network including such devices are also described.

  • Publication number: 20010015841
    Abstract: A method of and arrangement for buffering, during at least a predetermined retention time, a digital optical signal (S(i), i=0, . . . , 3) having a predetermined digital level is described. In one illustrative embodiment, the method includes inputting the optical signal (S(i)) to an optical input of a semiconductor laser element (SLE(i)) and injecting an injection current to the semiconductor laser element (SLE(i)) to establish an optical gain process in the semiconductor laser element (SLE(i)), the injection current having an amplitude such that the optical gain process and an optical absorption process within the semiconductor laser element (SLE(i)) outweigh one another longer than the retention time in order to keep the digital optical signal on the predetermined digital level during the retention time.
