Abstract: An LDPC parity check matrix, includes a systematic portion having a plurality of systematic elements having a value, the value each systematic element determining a cyclic shift to be applied to rows of an identity submatrix corresponding to that element; and a parity portion having a plurality of panty elements having a value, the value of each parity element determining a cyclic shift to be applied to rows of an identity submatrix corresponding to that element; wherein the weights of each column of a group of columns of the parity portion is the same. The LDPC parity check matrix may be used for data access, communication and storage, and may be used, for example for communications among a plurality of network nodes.

Abstract: A head-end equipment associated with a communication system configured to interface with an interference group (IG) composed of two or more modems is disclosed. The head-end equipment comprises a memory configured to store a plurality of instructions; and one or more processors configured to retrieve the plurality of instructions from the memory. In some embodiments, the one or more processors, upon execution of the plurality of instructions from the memory, is configured to generate an advanced warning signal to be provided to one or more modems associated with the IG. In some embodiments, the advanced warning signal comprises an information that a select modem, different from the one or more modems, in the IG will be initiating an upstream communication in a select frequency band, as well as information on a start time and a duration of the upstream communication.

Abstract: A method, system and computer program for transmitting at least two payloads in a downstream traffic phase of a time-division duplex (TDD) cycle with a single preamble from a headend followed by concatenated payloads without intervening preambles, whereby the payloads are ranked by increasing modulation profiles. The preamble, and concatenated and ordered set of payloads are then transmitted to two or more predetermined customer premise equipments (CPEs).

Abstract: A particular overall architecture for transmission over a bonded channel system consisting of two interconnected MoCA (Multimedia over Coax Alliance) 2.0 SoCs (Systems on a Chip) and a method and apparatus for the case of a “bonded” channel network. With a bonded channel network, the data is divided into two segments, the first of which is transported over a primary channel and the second of which is transported over a secondary channel.

Abstract: A connection device and system is disclosed that is made up of a flexible grid and durable connectors for removable insertion into spaces of the grid.

Abstract: Embodiments of the disclosure relate to adjustable and/or foldable play surfaces, that may include climbing surfaces, sliding surfaces, and/or other play structure surfaces. A foldable slide may comprise a slide surface; at least one side rail attached to the slide surface via at least one hinge, wherein the at least one side rail is configured to rotate with respect to the slide surface about the at least one hinge from a first position of the foldable slide to a second position of the foldable slide; and at least one attachment element configured to secure the at least one side rail into the second position.

Abstract: Embodiments may relate to a foldable play structure which may be easily assembled and which may be form of four or more panels each connected to another to provide an accordion fold structure; corner hinges comprising a first hinge portion attached to one panel of the at least four panels; a second hinge portion attached to another panel of the at least four panels; and a fastener configured to be retained within either the first portion or the second portion; and mid-wall hinge(s) attached to two of the panels and located between the corner hinges. Typically, in a first configuration, the panels of the accordion fold structure are folded to be stacked in substantially parallel planes, and in a second configuration, the panels are unfolded forming a play structure. The retained fastener may be used to secure the corner panels together.
