    • PURPOSE: Provided are a sensor apparatus and a safety apparatus which can ensure significantly enhanced safety by monitoring constantly whether the sensor apparatus is operating normally. CONSTITUTION: An auxiliary electrode plate(80) of a small area is disposed in parallel and in opposition to an electrode plate(26) with a short distance therefrom. A switching element(90) is turned on every second for a period of milliseconds repetitively. When the switching element(90) is turned on under the control of a central processing unit (74),m the auxiliary electrode plate(80) is connected to the ground potential, as a result of which a capacitance(DELTA C) effective between the auxiliary electrode plate(80) and the electrode plate(26) is electrically connected in parallel with a capacitor(C0) effective between the electrode plate(26) and a machine component(18), resulting in that the capacitance(C0) is increased by a proportion corresponding to the capacitance(DELTA C). Consequently, change of the capacitance(C0) comparable to that brought about upon detection of the human body takes place, whereby a substantially similar detection signal as the human body detection signal is made available. On the basis of this detection signal, it is possible to monitor whether or not the sensor apparatus(22) is operating normally.
    • 目的:提供传感器装置和安全装置,其可以通过不断监测传感器装置是否正常运行来确保显着增强的安全性。 构成:小面积的辅助电极板(80)平行放置,与距离短的距离的电极板(26)相对设置。 开关元件(90)每隔一秒重复开启几毫秒。 当在中央处理单元(74)的控制下开关元件(90)接通时,辅助电极板(80)连接到接地电位,结果电容(DELTA C)在 辅助电极板(80)和电极板(26)与在电极板(26)和机械部件(18)之间有效的电容器(C0)并联电连接,导致电容(C0)为 增加了对应于电容(DELTA C)的比例。 因此,发生与人体检测时相比的电容(C0)的变化,由此可以获得与人体检测信号基本相似的检测信号。 基于该检测信号,可以监视传感器装置(22)是否正常运行。

    • A laser interlocking system and a controlling method thereof according to one aspect of the present invention are able to protect eyes of an inspector and a person to be inspected and prevent unnecessary power consumption by generating a laser only in case the inspector and the person to be inspected wear safety glasses properly or photo-acoustic image equipment is actually used. The laser interlocking system according to one aspect of the present invention includes: a sensor unit which senses a contact between a user and safety glasses; a light source unit which generates a laser; and a control unit which determines whether the safety glasses are worn normally or not based on an output value which is outputted from the sensor unit and generates an interlocking signal which turns on or off the laser generation of the light source unit depending on the determined result.
