  • Reserving resources over a DOCSIS downstream external physical interface
    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.

  • Method for amplitude insensitive packet detection
    Patent number: 8085879
    Abstract: The invention relates generally to the field of wireless communications and more particularly to a method of and device for detecting the presence of a received data packet in a digital receiver. The present invention proposes a simplified method of correlation by removing dependency on the amplitude fluctuations while at the same time maintaining phase relevancy. The key advancement involves mapping the complex quadrature amplitude modulation (QAM) preamble to a quantized phase shift keying (PSK) constellation before application to a matched complex correlator. The proposed process essentially “amplitude normalizes” the input signal without the use or complexity associated with a divider. This simplified normalization scheme makes the packet detection algorithm robust against amplitude variations in the input signal, while still allowing for good correlation output.

  • Map message expediency monitoring and automatic delay adjustments in M-CMTS
    Patent number: 8081659
    Abstract: An M-CMTS compatible UEQAM device implements circuitry to identify and analyze MAP message in the data stream sent from the M-CMTS Core with respect to timing information embedded in those messages. The improved UEQAM will then create a specific message as an extension to DEPI to communicate that information to the M-CMTS Core. The M-CMTS Core will employ that analysis to automatically adjust MAP message advance time to reduce delay and thus improve system performance. This invention will provide a closed-loop between the M-CMTS Core and the UEQAM where valuable transmission information will periodically be fed back from UEQAM-to-M-CMTS Core in real-time.

  • Multiple frame grabber
    Patent number: 8068182
    Abstract: A system is presented that applies M×N×K computational units to calculating image parameters on N picture images captured simultaneously by N digital camera devices, where there are N groups of frame grabber units, each containing M frame grabbers in which there are K computational units. The data operated on by a computational unit is separate and independent from the image data operated on by the other computational units. This results in a performance speedup of M×N×K compared to one computational unit making the same computations. A master frame grabber unit controls the illumination of the N digital camera devices, and synchronizes the illumination with the clocks of the N digital camera devices.
