A passenger detecting system includes a plurality of antenna electrodes provided in a seat, a signal generating section, a detecting section, a switching circuit and a control unit. The signal generating section generates an electrode signal. The switching circuit sequentially supplies the electrode signal to the plurality of antenna electrodes one by one in response to a switching control signal. The detecting section detects change of the electrode signal to generate a detection signal when the electrode signal is supplied to each of the plurality of antenna electrodes. The control unit outputs the switching control signal to the switching circuit and generates a passenger data associated with a passenger on the seat based on the detection signal for each of the plurality of antenna electrodes.
摘要:
An exhaust manifold has dual liner structure constructed of an intermediate liner forming a chamber and a plurality of sleeves extending outwardly from the chamber and of an inner liner within the intermediate liner. The inner liner forms a reaction chamber within the chamber of the intermediate liner and a plurality of tubes extending outwardly from the reaction chamber and mounted within the sleeves, respectively. The tubes have inlet ports for connection to exhaust ports of an internal combustion engine. The reaction chamber is formed with a plurality of apertures opening to the chamber of the intermediate liner to let hot gases to flow into the chamber of the intermediate liner embracing the reaction chamber. The chamber of the intermediate liner is formed with an outlet port for connection to an exhaust pipe.

摘要:
First, an amount of a current flowing between a first wiring and a third wiring is estimated, and the number of stack vias required for connecting the first wiring and the third wiring is determined. Next, based on the number of stack vias, the number of virtual wirings for determining positions of the stack vias is determined. Thereafter, the virtual wirings are arranged in a forming region of the third wiring above the first wiring, for example, at an equal interval, and the stack vias are created in intersections of the first wiring and the virtual wirings. Thereafter, the virtual wirings are removed, and the third wiring is created. According to needs, a second wiring passing between the stack vias is created.
