    • A plasma actuator (1) includes four electrodes (11) and three dielectrics (10) and is disposed on the side of an object surface (B). When a high voltage is applied to the electrodes (11), a plasma (15) is generated at an end (10a) of each dielectric (10) exposed so as to be accessible to a gas. In the plasma actuator (1), the electrodes (11) and dielectrics (10) are alternately stacked one on another. The plasma actuator (1) includes a stepped exposed portion (X). The plasma actuator (1) in which the electrodes (11) and dielectrics (10) are arranged such that the ends (10a) of the dielectrics (10) are exposed in the normal line direction of the object surface (B) in the stacked order in the stepped exposed portion (X) can suppress the flow of the generated plasma even when the plasma actuator is exposed to a high-speed airflow under high pressure. This stabilizes the plasma.
    • 等离子体致动器(1)包括四个电极(11)和三个电介质(10),并且设置在物体表面(B)侧。 当向电极(11)施加高电压时,在暴露于气体可接近的每个电介质(10)的端部(10a)处产生等离子体(15)。 在等离子体致动器(1)中,电极(11)和电介质(10)彼此交替堆叠。 等离子体致动器(1)包括阶梯式暴露部分(X)。 等离子体致动器(1),其中电极(11)和电介质(10)布置成使得电介质(10)的端部(10a)在堆叠的物体表面(B)的法线方向上暴露 即使当等离子体致动器在高压下暴露于高速气流时,阶梯状暴露部分(X)中的阶数也可以抑制所产生的等离子体的流动。 这就稳定了等离子体。

    • An entry and exit control apparatus wherein missing entry and exit information on a user entering and exiting a controlled area by tailgating is complemented by entry and exit information on another user presumed to enter and exit the controlled area along with the user that is tailgating. Therefore, reliability of user entry and exit history is improved to sufficiently suppress a decrease in security in the controlled area. The entry and exit control apparatus estimates entry and exit date and time concerning the missing entry and exit information based on the statistically processed staying time information of the user and the traveling time information for the entry and exit date information of the user determined that a missing item is generated, extracts complementary entry and exit information from pieces of entry and exit information stored in an entry and exit history DB based on the estimated entry and exit date and time, and complements the missing entry and exit information on the user using the extracted complementary entry and exit information.
    • 入口和出口控制装置,其中通过尾随进入和退出受控区域的用户缺少入口和出口信息,与进入和退出信息相互补充,所述入口和出口信息被认为与被尾随的用户一起进入和退出受控区域。 因此,提高了用户进入和退出历史的可靠性,以充分抑制受控区域的安全性的降低。 进出出控制装置基于用户的统计处理的停留时间信息和用户的进入和退出日期信息的旅行时间信息来估计关于缺失的进入和退出信息的进入和退出日期和时间,确定丢失 根据估计的进入和退出日期和时间,从存储在入口和出口历史数据库中的条目和出口信息中提取补充进入和退出信息的补充进入和退出信息,并使用提取的 补充进出信息。
