  • Publication number: 20240413957
    Abstract: The techniques described herein relate to methods, apparatus, and computer readable media configured to schedule individual orthogonal frequency-division multiple access (OFDMA) resources on an upstream channel to serve a data transmission request from a downstream device. A schedule for a set of available resources on the upstream channel to serve the data transmission request is generated, based on a dynamic bit loading profile, including generating data indicative of a first bit loading profile for a first set of resources from the set of available resources for a first burst, and data indicative of a second bit loading profile for a second set of resources from the set of available resources for a second burst. The schedule is transmitted to a downstream device, such that the downstream device is configured to encode the first burst using the first bit loading profile and the second burst using the second bit loading profile.

  • Patent number: 10497567
    Abstract: Implementations described herein generally relate to an etching process for etching materials with high selectivity. In one implementation, a method of etching a gate material to form features in the gate material is provided. The method includes (a) exposing a cobalt mask layer to a fluorine-containing gas mixture in a first mode to form a passivation film on the cobalt mask layer. The cobalt mask layer exposes a portion of a gate material disposed on a substrate. The method further comprises (b) exposing the portion of the gate material to an etching gas mixture in a second mode to etch the portion of the gate material. The portion of the gate material is etched through openings defined in the cobalt mask layer and the portion of the gate material is etched at a greater rate than the cobalt mask layer having the passivation layer disposed thereon.

  • Publication number: 20140317645
    Abstract: The subject matter described herein relates to transmitting and displaying a channel of a television to a non-subscriber when a subscriber is viewing the channel so that both the non-subscriber and the subscriber can simultaneously view the channel. A channel is displayed to a subscriber of a service offering the channel. A presence status of the subscriber is monitored. The presence status characterizes a subscriber presence for viewing the channel. The presence status is displayed to one or more contacts of the subscriber, including the non-subscriber. The channel can be simultaneously displayed to the subscriber and the contacts of the subscriber for as long as the subscriber views the channel until a predetermined period of time. Related methods, apparatuses, systems, techniques and articles are also described.
