    • In an MIMO mobile communication system allowing a PDMA base station to communicate with a single terminal through a plurality of paths the terminal and the base station are each responsive to information of communication quality of a spatial path detected as having a reception error to appropriately control switching the path's communication operation between a plurality of types of operations. In a first operation, only a single path remains and the other paths are disconnected. In a second operation, path diversity is effected. In a third operation, path's modulation level is reduced. These operations are performed by a DSP. If in the MIMO system paths' mutual interference occurs the terminal and base station can still maintain connection.
    • 在允许PDMA基站通过多个路径与单个终端通信的MIMO移动通信系统中,终端和基站各自响应于检测到具有接收错误的空间路径的通信质量的信息,以适当地控制切换 该路径在多种类型的操作之间的通信操作。 在第一个操作中,只剩下一个路径,其他路径被断开。 在第二操作中,实现路径分集。 在第三操作中,路径的调制级别减小。 这些操作由DSP执行。 如果在MIMO系统路径中发生相互干扰,终端和基站仍然可以保持连接。

    • An airbag includes two base cloths sewn together at their outer peripheries by a seam extending from a central portion to the outer periphery of the base cloths into a vortical shape. When gas is supplied from an inflator to a center aperture of one of the base cloth to inflate the airbag, load generated by gas pressure breaks the seam sequentially from the central portion to the outer periphery, preventing sudden deployment of the airbag in fore and aft directions at the initial stage of deployment, thereby enabling not only soft restraining of passengers but also sufficient restraining by deploying the airbag into a final shape that is flat in fore and aft directions upon completion of breaking of the seam. The seam comprises a plurality of bonding portions such that the inflation breaks each of the bonding portions sequentially.

    • In an MIMO mobile communication system in which a PDM base station communicates with a single terminal through a plurality of paths the terminal and the base station each collectively transmit control message for a plurality of paths through a path best in communication quality as based on the plurality of spatial paths' communication quality information. Furthermore the communication quality information is referred to to appropriately control the path's communication operation to switch between a plurality of types of operation. A first operation increases the path's transmission power and a second operation decreases the path's modulation level. These operations are performed by a DSP. Thus in the MIMO system the control message can be transmitted more efficiently with increased certainty.
    • 在其中PDM基站通过多个路径与单个终端进行通信的MIMO移动通信系统中,终端和基站各自通过基于多个路径的通信质量最佳的路径共同地发送多条路径的控制消息 的空间路径通信质量信息。 此外,参考通信质量信息来适当地控制路径的通信操作以在多种类型的操作之间切换。 第一个操作增加了路径的传输功率,第二个操作降低了路径的调制电平。 这些操作由DSP执行。 因此,在MIMO系统中,可以以更高的确定性更有效地发送控制消息。

    • Four load sensors having an upper limit value in a detection range are mounted in a seat of a vehicle. The weight of an occupant sitting on the seat is detected as a total of outputs from the load sensors. When the detected weight of the occupant is equal or larger than a predetermined value, the deployment of the air bag is permitted, and when the detected weight of the occupant is smaller than the predetermined value, the deployment of the air bag is prohibited. When any one of the outputs from the plurality of load sensors is the upper limit value in the detection range, the deployment of the air bag is permitted irrespective of the detected weight of the occupant. Thus, even when the output from the load sensor has been modified to the upper limit value by a limiting process, so that the weight of the occupant is calculated as a value smaller than an actual weight to become smaller than the predetermined value, the air bag can be deployed reliably to restrain the occupant.
    • 具有检测范围中的上限值的四个负载传感器安装在车辆的座椅中。 坐在座椅上的乘员的重量被检测为来自负载传感器的总和的输出。 当检测到的乘员重量等于或大于预定值时,允许安全气囊的展开,并且当检测到的乘客重量小于预定值时,禁止安放气囊。 当来自多个负载传感器的输出中的任何一个是检测范围中的上限值时,无论检测到的乘员重量如何,均允许安全气囊的展开。 因此,即使当通过限制处理将负载传感器的输出修改为上限值时,使得乘员的重量被计算为小于实际重量的值以变得小于预定值,空气 袋可以可靠地部署以限制乘客。
