  • Patent number: 11971686
    Abstract: A dial, and timepiece including the dial, including a mother-of-pearl wafer partially covering a support member, and a decorative element arranged on a reverse of the wafer, the decorative element being visible on an obverse of the wafer when subjected to a stimulus and invisible on the obverse of the wafer in the absence of the stimulus. The decorative element has a first empty area on a reverse of the wafer, and a second empty area on the obverse of the wafer, facing the first empty area. A colour compensation layer is deposited on the first empty area or the second empty area, the colour being selected such that the difference in colour ?E in the CIE Lab colour space between the colour compensation layer and the decorative element in the absence of said stimulus, perceived by a user observing the obverse of the wafer, is less than 3.

  • Publication number: 20230026376
    Abstract: A local area network includes plural content delivery network CDN receiver devices so as to enable player-equipped terminals in the local area network to receive audio and/or video contents. The disclosed method includes: obtaining capacity information from the CDN receiver devices; selecting, according to the capacity information, at least one CDN receiver device for a session of delivering an audio and/or video content to the player; when the session ends, the selected at least one CDN receiver device holds in place, during a predefined time duration, processing resources for a potential upcoming session; when another session starts before expiry of the predefined time duration, the processing resources hold in place are used for the new session. And when another session starts after expiry of the predefined time duration, reselection of at least one CDN receiver device, according to updated capacity information, is performed.

  • Publication number: 20220044569
    Abstract: The present application discloses systems, methods, and computer-readable media that utilize computing devices to model multi-outcome transportation-value metrics that account for spatio-temporal trajectories across locations, times and other contextual features, and then utilize computer networks to dispatch provider devices to locations based on the multi-outcome transportation-value metrics. Moreover, the disclosed systems can utilize these multi-outcome transportation-value metrics and/or other models to manage and utilize dynamic transportation dispatch modes to more efficiently align provider devices and requestor devices across computer networks. For instance, the disclosed system can dispatch a provider device based on a discounted multi-outcome transportation-value metric.

  • Publication number: 20210314631
    Abstract: An audio-visual live content delivery system includes a client having access to a provider network via a gateway, an audio-visual live content delivering equipment comprising a multicaster for transmitting audio-visual live contents in multicast form via the provider network, a de-multicaster being able to perform a conversion in unicast form of audio-visual live contents received in multicast form from the multicaster, and a controller managing routing of requests to get audio-visual live contents. The client performs a discovery procedure aiming at receiving information on potential presence and availability of the de-multicaster. When the client intends receiving a targeted audio-visual live content, the client sends to the controller a request providing indication of presence and availability, or not, of the de-multicaster. Then the controller decides how redirecting the client to fulfill the request, according at least to the indication of presence and availability, or not, of the de-multicaster.

  • Patent number: 10700915
    Abstract: This document describes an adaptive bitrate streaming method allowing streaming an audio video (AV) content to a client device using a multi content delivery network (CDN) approach. Each CDN stores multiple versions of a content that can be requested in the form of a succession of consecutive files using HTTP requests. The method is based on a use of an intermediate module, called diversity module, between an AV player of the client device and each CDN of a plurality of CDN. For each file of a version of a content requested by the AV player, the diversity module requests a manifest file to each CDN and estimates a bitrate of each CDN using reception performances of the manifest files. Each file is requested by the diversity module in the form of a succession of groups of segments structured according to a pattern comprising a predetermined number of segments.

  • Patent number: 10652626
    Abstract: A gateway connects a first communication network comprising at least one terminal intended to consume multimedia contents and a second communication network via which the gateway is intended to receive the multimedia contents in a stream form. The gateway detects (400) a use of a unicast connection intended for transmitting a multimedia content from an original server to a terminal of said network via the gateway; seeks (403) a connection redirection rule according to information exchanged by the original server and the terminal; establishes (406) a multicast connection in order to receive the multimedia content; receives (407) the multimedia content in the form of a stream according to the multicast connection; and transmits (409) to the terminal the multimedia content in the form of a stream according to the unicast connection.

Each group includes one set of segments for each CDN, each set including segments to be requested to the CDN to which they correspond proportional to the bitrate of this CDN.

  • Patent number: 5105874
    Abstract: According to this process: the position in respect of height of the "molten metal (2)/liquid slag (3)" interface (M) is continuously determined. Further the position of an isotherm (IS) located at the "liquid slag (3)/powder layer (4)" interface is continuously determined by automatically controlling the position of a thermocouple (8) on this isotherm and by measuring the displacements of this thermocouple.By comparing the position in respect of height of the molten metal/liquid slag interface (M) with the position in respect of height of the isotherm (IS), the thickness and thus the variations in thickness of the liquid slag are continuously deduced.
