Abstract:
Described is an I/O driven, feedback based rate control mechanism that allows a transfer session to self-adjust its transfer rate in response to the speed of the storage device at the destination. The described system may operate at the application layer, which makes cross-platform deployment an easier task
Abstract:
A method of serving content to multiple clients via a network is provided. Independent sessions with each of a plurality of clients are maintained, wherein the number of clients in the plurality of clients can vary over time, and wherein the start of each session and the end of each session can be independent of the start and end of other sessions. A stream of packet payloads is received, each packet payload of the stream of packet payloads including data generated from the content, wherein each packet payload in at least a subset of the stream of packet payloads includes a different set of data. Each packet payload in the stream of packet payloads is transmitted to each client of the plurality of clients in corresponding packets, wherein the packet payload transmitted to a client at any particular time is independent of the state of the corresponding session.
Abstract:
This disclosure relates to network data communication. Some embodiments include initiating a network connection between an original source and an ultimate destination, transmitting a block of data from the original source to the ultimate destination on the network, requesting retransmission of lost blocks from the ultimate destination to the source and retransmitting the lost blocks from source to the ultimate destination. These embodiments further include measuring round-trip time of a retransmit request, the round-trip time measured from a time of transmission of a retransmit request from the ultimate destination to a time of reception at the ultimate destination after retransmission from the original source and setting the round-trip time as a minimum retransmission request time for the network connection, wherein the round-trip time includes latencies of the network connection and in data processes at the original source and at the ultimate destination.
Abstract:
In one embodiment, a system includes a fuel nozzle that includes a fuel injector configured to output a fuel flow and a premixer tube disposed about the fuel flow output from the fuel injector. The premixer tube includes a perforated portion and a non-perforated portion, and the non-perforated portion is downstream of the perforated portion.
Abstract:
A practical economic and technical model for building commercial-grade electronic file delivery services that provide the same scale, predictability, and differentiated service levels as physical courier services traditionally used to move electronic data on physical media. Systems and methods for providing such services using a charge-back scheme based on congestion pricing are described.
Abstract:
Un procédé de commande en fonctionnement d'un dispositif d'entraînement motorisé d'une installation domotique comprend au moins une étape (E10) d'entrée dans un mode de configuration du dispositif, une étape (E40) d'appairage d'un point de commande avec une unité électronique de contrôle du dispositif, une étape (E50) d'activation d'au moins un élément de sélection du point de commande au cours d'une période de temps prédéterminée démarrant suite à l'étape (E40) d'appairage et une étape (E80) d'entrée dans un deuxième état de veille d'un module de réception d'ordres de commande de l'unité électronique de contrôle. Le deuxième état de veille du module de réception d'ordres de commande présente une fréquence de réveil du module de réception d'ordres de commande inférieure à la fréquence de réveil du module de réception d'ordres de commande dans un premier état de veille.
Abstract:
Cet actionneur (1) sert à l'entraînement d'un écran autour d'un tube (2) fixe par rapport à un bâti. L'actionneur comprend des moyens (4) de fixation sur le tube (2) comportant au moins trois pièces (45a, 45b, 410, 420) aptes à exercer chacune un effort de serrage sur le tube (2) lorsque deux de ces pièces sont rapprochées par des moyens (9, 10) de réglage de l'effort de serrage. Les moyens (9, 10) réglage de l'effort de serrage sont distants de la surface extérieure (22) du tube (2), ce qui évite de fragiliser le tube (2).
Abstract:
A safety mechanism for a closing installation, comprising a shaft and an element having teeth for cooperating with a catch which oscillates during rotational movements of the shaft. The mechanism further comprises a safety system including a ring for braking the oscillatory movement of the catch. The movement of the ring is controlled by a detecting system that detects the state of a spring which used to compensate the torque exerted on the shaft by the screen body.
