  • Patent number: 11007957
    Abstract: A bumper structural body (100) includes a bumper reinforcement (10), energy absorbing members (30a, 30b), and intermediate members (50a, 50b). The sloped sections (12a, 12b) of the bumper reinforcement (10) are connected to the energy absorbing members (30a, 30b) and the intermediate members (50a, 50b). The intermediate members (50a, 50b) are each formed in a quadrilateral by connecting a first portion (51) contacting the energy absorbing member (30a, 30b), a second portion (52) contacting the bumper reinforcement (10), and portions connecting the first portion (51) and the second portion (52).

  • Patent number: 10513236
    Abstract: An energy absorbing member (20) is formed of an aluminum alloy extruded material having a substantially quadrangular outer shape. Straight portions of a pair of long sides of a quadrangular shape are each segmented into three side walls (21a, 21b, 21c) by two arcuate internal projections (26) that project inward. Vertices of opposing internal projections (26) are joined by a rib (25). Accordingly, the energy absorbing member (20) is configured to have a shape in which three cylindrical portions having hollow portions (24a, 24b, 24c) are joined. Arc-shaped internal projections (23) that each project inward are provided in four corners of the quadrangular shape.

  • Patent number: 7995522
    Abstract: A base station and a router are interactively connected by a multilink group which transmits VoIP packets and a multilink group which transmits data packets other than VoIP packets. The base station and the router split transmission lines by referencing the ToS area of received packets and transmit only VoIP packets by way of a dedicated line. In this way, VoIP packets can be transmitted without being affected by other data packets, and the quality of VoIP can be warranted on the mobile network.
