Abstract: A channel sensing device for detecting preamble transmission by observing a channel sensing sequence of a length smaller than or equal to a maximum given length, the channel sensing device being implemented in a receiver, the channel sensing sequence includes one or more samples. The channel sensing device is configured to: receive input parameters comprising a target reliability metric, a receiver noise profile, the maximum given length, a received power, and a probability of there being a preamble; determine channel sensing parameters given the input parameters and according to the inimization of the average energy consumption per given length, the channel sensing parameters comprising a number of channel sensing phases, and a number of samples, a receiver power consumption value, and a preamble detection threshold corresponding to each of the channel sensing phases; perform a first channel sensing phase comprising: observing a batch of samples of the one or more samples by consuming the receiver power consumption value corresponding to the first phase channel sensing phase; applying a hypothesis test comprising the comparison of a value derived from the observed samples with the preamble detection threshold corresponding to the first channel sensing phase; deciding on the presence of a preamble or on performing a subsequent channel sensing phase based on the comparison and/or whether the number of channel sensing phases is greater than one; a subsequent channel sensing phase comprising: observing a batch of samples by consuming the receiver power consumption value corresponding to the channel sensing phase; applying a hypothesis test comprising the comparison of a value derived from all of the so far observed samples with the preamble detection threshold; deciding on the presence of a preamble or on performing a subsequent channel sensing phase based on the comparison and/or on a condition related to a number of performed channel sensing phases compared with the number of channel sensing phases.

Abstract: Methods, systems, and non-transitory computer readable storage media are disclosed for rendering portions of a three-dimensional environment at different sampling rates based on a focus frame within a graphical user interface. Specifically, the disclosed system provides a tool for marking a region of a graphical user interface displaying a three-dimensional environment. The disclosed system generates a focus frame based on the marked region of the graphical user interface and attaches the focus frame to a portion of the three-dimensional environment. The disclosed system assigns a first sampling rate to the portion of the three-dimensional environment displayed within the focus frame and a second sampling rate to portions of the three-dimensional environment outside the focus frame. The disclosed system renders the three-dimensional environment by sampling the portion within the focus frame at the first sampling rate and the portions outside the focus frame at the second sampling rate.

Abstract: Methods, systems, and non-transitory computer readable storage media are disclosed for generating enriched light sources by utilizing surface-centric representations of three-dimensional surfaces. Specifically, the disclosed system utilizes a surface-centric re-parameterization that combines geometric and algebraic components of a sphere to model different light source types in a continuous range of lighting configurations. The disclosed systems utilize a set of intuitive parameters to determine a shape and emission parameters for generating an enriched light source. Additionally, the disclosed system provides a set of interactive light source controls to modify a position, orientation, shape, emittance, and lighting attenuation over distance of a light source within a three-dimensional environment. The disclosed system determines the light source controls based on sets of three-dimensional interaction primitives to control one or more parameters of the light source. The disclosed system provides the light source controls for consistently modifying various light source types within the three-dimensional environment.

Abstract: The invention relates to a method for broadcasting a spatialized audio stream to terminals of spectators attending a sports event. The method comprises the acquisition of a plurality of audio streams constituting a soundscape. The soundscape is analyzed by a server in order for the sound spatialization of the audio streams and of the playback thereof on terminals, depending both on the localization of the audio flows and also the position of the spectators.
