    • A pressure sensor includes a case, a vibrator, a detector, and a processor. The case includes a tubular section and a flat section. The tubular section has a hollow having an opening and is configured to be filled with a target fluid. The flat section closes the hollow. The flat section has a first surface facing the hollow, and a second surface opposite to the first surface. The vibrator is disposed on the second surface of the flat section of the case. The detector outputs a signal according to a vibration of the vibrator. The processor is operable to detect a frequency of the vibration of the vibrator based on the signal output from the detector, and to detect a pressure of the target fluid based on the detected frequency of the vibrator. This pressure sensor has a high sensitivity and excellent characteristics.
    • 压力传感器包括壳体,振动器,检测器和处理器。 壳体包括管状部分和平坦部分。 管状部分具有一个具有开口的中空部分,并被构造成填充有目标流体。 扁平部分封闭空心。 平坦部分具有面向中空部的第一表面和与第一表面相对的第二表面。 振动器设置在壳体的平坦部分的第二表面上。 检测器根据振动器的振动输出信号。 处理器可操作以基于从检测器输出的信号来检测振动器的振动频率,并且基于检测到的振动器的频率来检测目标流体的压力。 该压力传感器具有高灵敏度和优异的特性。

    • A present locking device is a locking device for locking/unlocking a lock of a door of a closed space, including: a first transmission antenna for transmitting a first signal to a range including an outside of the closed space; a second transmission antenna for transmitting a second signal to an inside of the closed space as a target; a key which transmits a first response signal when receiving the first signal and not receiving the second signal, and which transmits a second response signal when receiving the first signal and also receiving the second signal; a reception antenna for receiving at least the first response signal from the key; and a control unit for controlling whether locking or unlocking can be performed on the lock or not, based at least on whether the reception antenna receives the first response signal or not.
    • 本发明的锁定装置是用于锁定/解锁闭合空间的门的锁定装置,包括:用于将第一信号发送到包括封闭空间外部的范围的第一发送天线; 第二发送天线,用于将第二信号发送到作为目标的封闭空间的内部; 当接收到第一信号而不接收第二信号时发送第一响应信号,并且在接收到第一信号时发送第二响应信号并且还接收第二信号的密钥; 接收天线,用于至少从所述密钥接收所述第一响应信号; 以及控制单元,用于至少基于接收天线是否接收到第一响应信号来控制是否可以对锁进行锁定或解锁。
