    摘要： The present disclosure disclose a diaphragm dome, the diaphragm dome includes a first carbon fiber layer and a second carbon fiber layer which are alternatively arranged by stacking, the first carbon fiber layer and the second carbon fiber layer are respectively a single-layer structure formed by an one-way extended carbon fiber bundle, an extending direction of the carbon fiber bundle of the first carbon fiber layer is perpendicular to an extending direction of the carbon fiber bundle of the second carbon fiber layer, and a thickness difference exists between the first carbon fiber layer and the second carbon fiber layer. In the diaphragm dome provided by the present disclosure, the material has larger specific strength, thus can reduce the thickness of the diaphragm dome, the carbon fiber layers of the diaphragm dome are well adhered, which is not readily layered, and has good water resistance.

    摘要： This invention discloses methods and circuits of wideband wireless transmitting and/or receiving by combining multiple RF transmitters and/or receivers, or multiple transceivers, each of which has a narrower bandwidth, e.g., producing a RF transmitter and receiver or a RF transceiver whose signal bandwidth is the sum or approximately the sum, e.g., slightly less than the sum, of the signal bandwidth of the multiple RF transmitters and/or receivers, or multiple RF transceivers. The embodiments apply in wireless communication systems with orthogonal or approximately orthogonal subcarrier type of modulation (OSM), e.g., Orthogonal Frequency Division Multiplexing (OFDM).

    摘要： This invention describes a method, the information processing system and the autonomous vehicles that enable in-person socializing of passengers in multiple traveling autonomous vehicles. Under the collaborative control of one or more information processing system and on-bard controllers, multiple traveling autonomous vehicles carrying passengers who have matching interests or requests, overlapping travel routes and times are connected together mechanically while traveling at normal operating speed to establish a connected space to allow in-person interactions and socializing. A cluster of connected autonomous vehicles moves as one integrated vehicle.
