  • Patent number: 10413953
    Abstract: A composite structure includes a base and an auxiliary portion of dissimilar materials. The auxiliary portion is shaped by stamping. As the auxiliary portion is stamped, it interlocks with the base, and at the same time forming a desired structured feature on the auxiliary portion, such as a structured reflective surface, an alignment feature, etc. With this approach, relatively less critical structured features can be shaped on the bulk of the base with less effort to maintain a relatively larger tolerance, while the relatively more critical structured features on the auxiliary portion are more precisely shaped with further considerations to define dimensions, geometries and/or finishes at relatively smaller tolerances. The auxiliary portion may include a composite structure of two dissimilar materials associated with different properties for stamping different structured features.

  • Patent number: 10389564
    Abstract: The present invention is designed so that, in a radio communication system in which inter-terminal communication is carried out, the impact of inter-symbol interference due to the delay of inter-terminal discovery signals is reduced. The radio communication method of the present invention is used in a radio communication system in which each user terminal transmits the inter-terminal discovery signal in a transmission duration of a predetermined period. A radio base station determines the cyclic prefix (CP) length configuration for use in the transmission duration, and transmits cyclic prefix (CP) length configuration information which represents the CP length configuration. Each user terminal transmits the inter-terminal discovery signal based on the CP length configuration information.
