Patent EP-3827294-A1 (EP)
Title: Éléments optiques de diffraction à atténuation de perte de lumière induite par rebond et systèmes et procédés associés
Inventor: Schmulen Jeffrey Dean
IPC: G02B6/122
Filed: 2019-07-23
Abstract: L'invention concerne des dispositifs d'affichage qui comprennent des guides d'ondes ayant des éléments optiques de couplage d'entrée qui atténuent un rebond d'une lumière couplée en entrée pour améliorer l'efficacité et/ou l'uniformité globales de couplage d'entrée. Un guide d'ondes reçoit une lumière à partir d'une source de lumière et/ou d'une optique de projection et comprend un élément optique de couplage d'entrée qui couple en entrée la lumière reçue pour qu'elle se propage par réflexion interne totale dans une direction de propagation à l'intérieur du guide d'ondes. Une fois couplée en entrée dans le guide d'ondes, la lumière peut subir un rebond, dans lequel la lumière se réfléchit sur une surface de guide d'ondes et, après la réflexion, frappe l'élément optique de couplage d'entrée. Lorsqu'elle frappe l'élément optique de couplage d'entrée, la lumière peut être partiellement absorbée et/ou découplée par l'élément optique, ce qui réduit efficacement la quantité de lumière couplée en entrée se propageant à travers le guide d'ondes. L'élément optique de couplage d'entrée peut être tronqué ou avoir un rendement de diffraction réduit le long de la direction de propagation pour réduire l'apparition d'une perte de lumière due à un rebond de la lumière couplée en entrée, ce qui entraîne que moins lumière couplée en entrée est prématurément découplée et/ou absorbée au cours d'interactions ultérieures avec l'élément optique de couplage d'entrée.

Abstract: This application provides a message transmission method, an apparatus, and a storage medium. The method includes: receiving, by a first transmission proxy, a first message from a first service instance, where the first message includes an identifier of a first service set; obtaining, by the first transmission proxy, a second service instance in the first service set based on the identifier that is of the first service set and that is included in the received first message; and sending, by the first transmission proxy, a second message to the second service instance based on the first message. In this way, the first transmission proxy may select the second service instance for the first service instance from the first service set, without participation of the second service instance and/or the first service instance. This helps simplify complex service logic of a service instance.

Abstract: This invention consists a Master Dimmer and one or more Dimming Control Modules. This invention uses embedded pulse width modulation signal to carry out phase control dimming for lighting equipment. 
     The Master Dimmer consists of a Code Detection Circuit (1), an Input Protection Circuit (2), a Power Supply and Synchronization Circuit (3), a Phase Cutting and Protection Circuit (4), a Main Control Circuit (5) and a Dial Switch and Encoder Circuit (6). 
     The Dimming Control Module Consists of a Dimming Control Module Input Protection Circuit (7), a Dimming Control Module Encoder circuit (8), a Dimming Control Module Power Supply and Synchronization Circuit (9), a Dimming Control Module Control Circuit (10) and a Dimming Control Module Dial Switch and Encoder Circuit (11). 
     Communication between the Master Dimmer and one or more Dimming Control Module are carried out on a communication wire (S) which connects between them. Encoded control signals are embedded onto the voltage carrying communication wire (S) for the communication between the Master Dimmer and all the Dimming Control Modules. The Master Dimmer is the only device which connects to the load (lamps). Dimming Control Modules send embedded control commands to the Master Dimmer and the Master Dimmer will decode the control commands and then carry out phase control dimming to the load (lamps). The Master Dimmer has it's own dial control to control the brightness of the load. Therefore, both the Master Dimmer and the Dimming Control Modules can control the brightness of the load (lamps). The combination of Master Dimmer and Dimming Control Modules provides a simple multi locations dimming control system. Since the communication between the Master Dimmer and Dimming Control Modules are made via a single communication wire (S) and the Live wire (L) of main power supply, the existing in-wall wiring of the 2-way and 3-way circuits can be used, i.e., without the requirement of rewiring the in-wall wires. This will make the retrofit process a lot easier, faster and cheaper.
