  • Publication number: 20150304744
    Abstract: A radio frequency over glass (RFoG) system may be modified to extend a downstream band. A transimpedance amplifier with a downstream path may be used in the RFoG system in combination with an upstream path having greater than 200 MHz radio frequency (RF) bandwidth to provide the greater than 1.2 GHz downstream bandwidth overlapping with the greater than 200 MHz upstream bandwidth. The RFoG system may include a gateway facilitating an optical network unit and modem connection, the gateway having an express upstream port and an express downstream radio frequency (RF) port. The gateway may be configured for processing legacy RFoG signals in an upstream and a downstream direction and for at least one of generating or processing, via the express ports on the modem, RFoG signals in an extended spectrum beyond 42 MHz in the upstream direction and beyond 1000 MHz in the downstream direction.

  • Patent number: 9155552
    Abstract: The invention relates to systems for removing obstructions and other objects within a blood vessel or other interior lumen of an animal. The system may be deployed in the lumen from a catheter and includes a pull wire having a proximal end and a distal end, and a distal body having a proximal hub, a basket, and a distal hub. In some embodiments, the distal body includes a plurality of proximal strips that form a closeable claw that is used to capture the obstruction. In other embodiments, the basket includes an enlarged opening that allows the object to enter the basket. Optionally, the basket includes x-ray markers adjacent to the enlarged openings to allow the operator to locate the openings, as well as twisting strips that connect the basket to the proximal hub. The present invention also relates to methods of making and using such systems.

  • Publication number: 20150280816
    Abstract: An OBI manager provides the reduction/elimination of optical beat interference (OBI). As will be described in more detail below, the OBI manager identifies OBI partners through an identification process performed via an RFoG network. An OBI partner may be two optical networking units (ONUs) that may interfere with one another when transmitting in the same time slot. Once the OBI partners are identified, the OBI manager may perform a mitigation process to mitigate possible OBI. For example, the OBI manager may organize the OBI partners to reduce OBI, such as by guaranteeing no OBI partners transmit at the same time.

  • Patent number: 8900265
    Abstract: The present invention relates to a system for removing obstructions and other objects within a blood vessel or other interior lumen of an animal. The system may be deployed in the lumen from a catheter and includes a pull wire having a proximal end and a distal end, and a distal body. Optionally, the distal body includes a plurality of memory metal strips that form a closeable claw that is used to capture the obstruction. Optionally, the memory metal strips are connected to a proximal hub that is slideable along at least a segment of the pull wire and the memory metal strips are moved towards each other and towards the pull wire by moving the proximal hub distally towards a stationary distal hub, which in turn, causes the claw to close and capture the obstruction. The present invention also relates to methods of making and using such systems.

  • Patent number: 8654640
    Abstract: A system and method receives IP packets on a first device for delivery as DOCSIS packets over a DOCSIS interface, each DOCSIS packet encapsulating IP data from the IP packets, and including a sequence number that the first device generates for a bonding group. The method delivers first DOCSIS packets to a DOCSIS device using first downstream channels on the first device that are associated with the bonding group. When the first downstream channels exceed a capacity, the method determines an available capacity of second downstream channels on a second device that are associated with the bonding group, identifies second DOCSIS packets that do not exceed the available capacity, and forwards the second DOCSIS packets to the second device, which delivers the second DOCSIS packets to the DOCSIS device using the second downstream channels.

  • Patent number: 8468571
    Abstract: A method and system for enabling trick plays during a variable bit rate (VBR) playback of a media file transmitted to a user media device as a constant bit rate (CBR) flow includes determining a plurality of access points within the media file. The media file is configured to be played back from each of the plurality of access points. A minimum buffer value is calculated for each of the plurality of access points. The minimum buffer value identifies a minimum amount of the media file to transmit to the user media device before beginning playback of the media file from each of the plurality of access points to substantially ensure that the media file is configured to be played back from each of the plurality of access points continuously and uninterruptedly at a variable bit rate.

  • Publication number: 20090310596
    Abstract: An apparatus, method and system for delivering Internet content within a system that includes a bypass architecture, such as a bypass architecture that transmits content from the Internet or an Internet content source to a downstream modulator, such as an Edge Quadrature Amplitude Modulation (EQAM) modulator, in a manner that bypasses the system's Cable Modem Termination System (CMTS). Content from the Internet or an Internet source is transmitted to a last-hop router, which is configured to identify content for bypass encapsulation. The last-hop router also can be configured to perform at least a portion of the necessary bypass encapsulation for proper bypass flows of the identified content. Alternatively, the EQAM is configured to perform the bypass encapsulation, and the last-hop router transmits the identified content to the EQAM, which performs at least a portion of the necessary bypass encapsulation on the identified content.

  • Patent number: 6098131
    Abstract: A network apparatus having a chassis with an external network data port and a removable electronic module coupled to the network data port through an internal data port when the removable electronic module is present in the chassis. The chassis may also provide power, radio frequency (RF), data bus, and other types of electrical and data connections to the electronic module through the use of additional internal ports. The apparatus may additionally be connected to others via a data bus, and be included as part of a rack-mounted system. The electronic module may be inserted and removed from the chassis while electrical power is applied to the chassis.

  • Patent number: 5608728
    Abstract: A system and method for equalization for forward and reverse channels of communicating highway network system having a branching tree topology. The system and method cause the forward channel to be adjusted first for equalization, then the reverse channel is adjusted for equalization. A reference node periodically transmits a frequency-rich signal on the network to the head end, which broadcasts this signal to each of a number of system nodes. Each system node compares the frequency-rich signal with an expected signal, and adjusts its receiver based on this comparison. Next, each system node transmits another frequency-rich signal to the head end, receives a return echo, compares the echo with the transmitted signal, and adjusts its transmitter based on the comparison.

  • Patent number: 5471474
    Abstract: A communications highway network system for the interactive communication of digital and analog information that incorporates LAN, MAN, and CATV technology to provide an information pathway of metropolitan size that has a spanning tree topology. The system is multiple drop that operates according a network protocol. The network protocol is based on modified TDM techniques, compensation for round trip loop delay, dynamic allocation of time slots on the network bus, and global synchronization. The protocol also permits concatenation of data packets to reduce overhead. Access to the network bus is controlled by a system allocator operating according to the network protocol. The allocator may allocate network bus bandwidth to simultaneously provide three levels of service for the system nodes to access the network bus, namely, isochronous, demand-based dedicated, and contention bandwidth allocation. This allocation method incorporates fairness to give all nodes sufficient bus access opportunities.
