摘要： A network for sensing video noise power over a wide dynamic range and outting a voltage proportional to that noise power. The input signal is filtered, inverted and rectified to separate the noise component from the signal. The noise component is then converted to a negative level voltage which is added to first and second preset voltages. A non-linear output voltage which is a function of the first signal sum is provided for driving the voltage threshold devices in external equipment. A linear voltage output which is a function of the second signal sum is also provided for driving the voltage threshold devices of external equipment.

摘要： An electric switch assembly having a switch arm movable from "on" to "off" position and a cover plate through which the switch arm extends. The cover plate has an integral guard providing a stop substantially abutting the switch arm when in one of its "on" and "off" positions and blocking movement of the switch arm to the other position. The cover plate may replace the conventional cover plate or serve as an auxiliary cover plate applied over the conventional cover plate.
摘要翻译：一种电开关组件，其具有可从“接通”到“断开”位置的开关臂，以及开关臂延伸穿过的盖板。盖板具有整体的防护件，当处于其“开”和“关”位置中的一个位置时，提供大致邻接开关臂的止挡件，并阻止开关臂移动到另一位置。盖板可以替代传统的盖板或用作应用在传统盖板上的辅助盖板。

摘要： A safety alarm for a weapon such as a hand gun is provided that is mounted in the hand grip of the weapon to warn of possible impending use by either an authorized or an unauthorized person. The safety alarm is mounted within the hand grip and has an alarm connected electronically to a battery in a normally open circuit that is closed only when a switch within the circuit is activated. In one embodiment the switch is in the form of a plunger that extends outside of the grip and is engaged by the hand to be depressed to connect two electronic contacts to complete the circuit and sound the alarm. In another embodiment the switch is in the form of a motion detector such as a mercury switch so that when the weapon is moved from one position in which the circuit is normally opened, the circuit is closed to connect the alarm to the battery and sound the alarm.
摘要翻译：提供武器如手枪的安全报警器，其安装在武器的手柄中，以警告被授权或未经授权的人员可能即将使用。安全报警器安装在手柄内，并且具有以常开电路的电池电连接的报警器，仅在电路内的开关被激活时才关闭。在一个实施例中，开关为柱塞的形式，其延伸到手柄外部并且被手接合以被按压以连接两个电子触点以完成电路并发出警报。在另一个实施例中，开关是诸如水银开关的运动检测器的形式，使得当武器从电路正常打开的一个位置移动时，电路闭合以将警报连接到电池并且将声音报警。
