  • Patent number: 9112816
    Abstract: In one example, an Edge Quadrature Amplitude Modulation (EQAM) communicates EQAM information to a Modular Cable Modem Termination System (M-CMTS) core using a routing protocol that is configured on a packet switched network coupling the EQAM to the M-CMTS core. The EQAM generates a routing message according to the routing protocol and inserts EQAM information, such as a description of a modulated channel extending from the EQAM, the service-group information, etc., into the routing message. The EQAM then floods the EQAM information over at least portions of a routing domain by transmitting the routing message to an adjacent intermediary device.

  • Publication number: 20140348505
    Abstract: A Data Over Cable Service Interface Specifications (DOCSIS) Passive Optical Network (PON) system (DPON) makes optical subscribers appear as cable subscribers. In one embodiment, a Cable Modem (CM) proxy is located in an Optical Line Termination (OLT). The OLT implements a cable modem protocol stack that operates as the CM proxy and communicates with a back office system. The OLT translates the data retrieved by the CM proxy into Optical Network Unit (ONU) recognizable commands, and sends the translated data to the ONU. In a second embodiment, the CM proxy is located in the ONU. The ONU implements the cable modem protocol stack that operates as the CM proxy and communicates with the back office system. The ONU translates the data retrieved by the CM proxy into ONU recognizable commands and sends the translated data to the ONU.

  • Patent number: 8805522
    Abstract: A dressing for treating a damaged tissue, incorporates a pair of electrodes and a conductive gel between the electrodes. An electric current passes between the electrodes through the gel to repair the damaged tissue. Sensors can be incorporated into the dressing along with a control unit. The control unit can vary the current supplied to the electrodes according to environmental parameters detected by the sensors. Alternatively, one or more pre-defined programs can be stored in the control unit for supplying an alternating current to the electrodes with a varying amplitude, frequency and waveform.

  • Patent number: 8599842
    Abstract: In one embodiment, label distribution sessions are established between a Modular Cable Modem Termination System (M-CMTS) core and one or more remote PHYs. The label distribution sessions facilitate association of labels with either Radio Frequency (RF) channels or groups of the RF channels that extend from the remote PHYs to one or more cable modems. The labels are then used to facilitate communications between the M-CMTS core and the remote PHYs over a MultiProtocol Label Switching (MPLS) network.

  • Publication number: 20130072903
    Abstract: An improved method for preparing an adipose tissue biocomposite graft to serve a wide range of medical applications is presented. In particular, the embodiments consider a performing lipoplasty to derive a plurality of adipose tissue fragments containing at least one viable stem cell from a donor, harvesting said plurality of adipose tissue fragments from said donor, placing said plurality of adipose tissue fragments in contact with appropriate concentrations of a thrombin source and a fibrinogen source to achieve an appropriate gelling reaction and applying the mixture of said adipose tissue fragments, said thrombin source and said fibrinogen source to a wound site of the donor so as to promote wound healing. The adipose biocomposite graft of the present invention can be easily processed, molded and customized to precise dimensions. The present invention employs a three dimensional mold cavity to prepare multiple castings of said adipose tissue biocomposite grafts for an individual donor.

  • Patent number: 8397267
    Abstract: In one embodiment, upstream transmission throughput in a cable network is markedly increased by moving up the US/DS frequency split by approximately an order of magnitude to a few hundred MHz. Additional transceivers (carriers) may be implemented to take advantage of the broader spectrum. A block of multiple upstream carriers (FIG. 2A) are associated to form a single logical upstream providing a high-bandwidth, in-order packet stream. The carriers have a common start time (704), pursuant to a single MAP message, and operation synchronously to transmit an upstream transmission frame (250). They may use OFDM or discrete carriers. A convergence layer (350) assembles the data from all of the upstream channels (320,322,324) for presentation to the MAC layer logic (308,310) as a single, serial, high-speed transmission from the CM.

  • Patent number: 8089983
    Abstract: In one example, a resource reservation protocol is modified to allow a Modular Cable Modem Termination System (M-CMTS) core to use the protocol to reserve, for a flow, network resources as well as a Radio Frequency (RF) channel extending from the remote PHYsical interface (PHY). The modifications allow the M-CMTS core to identify parameters to be used by the edge device for selecting an available RF channel to be reserved for the flow, or to request a particular one of the RF channels. Intermediary devices operating on the DEPI can also reserve resources for the flow without being reconfigured according to the protocol modifications.
