  • Publication number: 20220010578
    Abstract: The detailed principle, structure, manufacture and designing method of a retractable roof for large stadiums or other huge spaces are established. This roof is formed by using a number of connected and paralleled inflatable arc shaped tubes (called “air beams”) made of soft material (membrane). Using successive inflation to the tubes can realize deploying of the roof, and using successive deflation of tubes can realize retraction of the roof. All these processes can be completed by an automatically controlled program. A rigorous mathematics derivation and mechanics proof show that, the retractable air beam roof with durable membrane of ordinary durability can have a large span of over 100 meters, and can withstand in a regularly extreme (critical) weather (heavy wind, rain, snow and hail). The outstanding strong point of this kind of retractable roof is absolutely safe for spectators and performers (or competitors) inside the stadium.

  • Publication number: 20210249013
    Abstract: An apparatus supports smart assistant services with a plurality of smart service providers. The apparatus includes an audio device that receives a speech signal having a user utterance, captures the user utterance when the user utterance includes a user wake word, and sends the captured utterance to a backend computing device. The backend computing device replaces the user wake word with specific wake words associated with different smart service providers. The processed utterances are then sent to selected smart service providers. The backend computing device subsequently constructs feedback to the user utterance based on voice responses from the different smart service providers. The backend computing device then passes a digital representation of the feedback to the audio device, and the audio device converts the digital representation to an audio reply to the user utterance.
