A heat transfer assembly may be used to provide a thermal conduit from a module mounted on a circuit board through the circuit board, allowing a thermal path away from the module. The heat transfer assembly generally includes a thermally conductive base with at least one raised thermal pedestal accessible through at least one heat transfer aperture in the circuit board and in thermal contact with the module. In an embodiment, the heat transfer assembly is used in a remote PHY device (RPD) in an optical node, for example, in a CATV/HFC network. The RPD includes an enclosure having a base with at least one raised thermal pedestal in thermal contact with an optical module (e.g., an optical transmitter or transceiver) on a circuit board through at least one heat transfer aperture in the circuit board.

Energy reduction in a CATV network device, such as an optical node, in a CATV network may be accomplished using a system and method for controlling an amplifier in response to channel loading. The system and method detects a channel loading condition for a CATV RF signal including a plurality of utilized channels across a channel spectrum defining a plurality of potential channels. The channel loading condition may be detected by scanning the CATV RF signal to measure the channel loading or by obtaining channel loading data from a remote PHY device (RPD) located in the optical node. The system and method then obtains an amplifier operating parameter associated with the channel loading condition and applies the amplifier operating parameter to control power consumption of an amplifier in the optical node (e.g., by changing bias current) in response to the channel loading condition.

A computer-implemented method for interacting with a file stored on a computing device that includes a display. The method includes causing a first user interface element to be displayed; receiving user input; determining that the user input is received for a duration of time greater than a threshold value; and, in response to determining, causing a first full tab to be displayed on a first side of the first user interface element, where the first full tab is associated with a first function for manipulating the file.

Tabs for managing content

A method that includes causing at least a portion of a first representation of a first file and at least a portion of a second representation of a second file to be displayed in a user interface on a display associated with a computing device, where the first file is included in a first folder included in a folder structure stored in a memory included within the computing device, and the second file is included in a second folder included in the folder structure. The method further includes receiving user input to navigate content stored in the folder structure, and, in response to the user input, causing the at least a portion of the first representation and the at least a portion of the second representation to move in a first direction within the user interface.

Upstream data handling in a digital Data Over Cable Service Interface Specification (DOCSIS) passive optical network (DPON). Embodiments include receiving at a headend, in an upstream path over an optical network, a plurality of digitized and serialized DPON upstream packets respectively distributed in a time division multiplexed fashion, wherein each DPON upstream packet includes a header, a trailer and a payload, monitoring the optical network for energy in the upstream path, including energy associated with a header and a trailer of respective DPON upstream packets, controlling a bit stuffer that adds bits to the upstream path to (1) stop adding bits to the upstream path when energy is detected in the upstream path and (2) resume adding bits to the upstream path after an end of a trailer of a given DPON upstream packet has been detected, and removing the header and the trailer of the respective DPON upstream packets. The resulting original payload is then digital to analog converted, and the resulting data is passed to, e.g., a cable modem termination system (CMTS).
