    • A safety circuit for use in low-voltage systems improves safety of and additional features to low-voltage connections. When incorporated into a battery, the circuit leaves the battery disconnected from the low-voltage system until it determines that it is safe to make a connection. When the safety circuit determines that no unsafe conditions exist and that it is safe to connect the battery, the safety circuit may connect the battery by way of a “soft start” that provides a connection over a period of time that reduces or prevents inductive voltage spikes on the low-voltage system. A method is used for detection of proper polarity of the connections between the battery and the low-voltage system. When incorporated into a jumper cable, the safety circuit provides communication abilities, can provide test abilities, and improves connection safety and functionality, such as allowing transfer of power between low-voltage systems having different voltages.
    • 用于低压系统的安全电路提高了低压连接的安全性和附加功能。 当电池并入电池时,电路将电池从低压系统断开,直到确定连接是安全的。 当安全电路确定不存在不安全的条件并且连接电池是安全的时,安全电路可以通过“软启动”来连接电池,该软启动在一段时间内提供连接,以减少或防止感应电压 尖峰在低压系统上。 一种方法用于检测电池和低压系统之间的连接的正确极性。 当安装在跳线电缆中时,安全电路提供通信能力,可提供测试能力,并提高连接安全性和功能性,例如允许在具有不同电压的低压系统之间传输电力。

    • A safety outlet that prevents hazardous conditions is described. Embodiments of the outlet use safe low-voltage DC power to check and ensure that an appliance is plugged into the outlet, that the appliance does not have short circuits or ground faults, and that the appliance is switched on. Some embodiments warn of unsafe conditions. Until the safety checks are performed and satisfactorily passed, embodiments of the outlet keep the AC power turned off and isolated from the outlet. Only then is the receptacle powered, after which the appliance can be used normally. Once the appliance is switched off, the power at the outlet is also turned off automatically. When an appliance is in use, some embodiments of the invention continue providing ground fault protection using GFCI technology. All this is performed automatically and quickly, nearly imperceptibly in normal use. Some embodiments may be integrated with external control systems.
    • 描述了防止危险状况的安全出口。 插座的实施例使用安全的低压直流电力来检查并确保器具插入插座,器具没有短路或接地故障,并且器具被接通。 一些实施例警告不安全的条件。 直到执行安全检查并令人满意地通过,插座的实施例保持AC电源被切断并与出口隔离。 只有在插座供电的情况下,才能正常使用电器。 一旦设备关闭,出口电源也会自动关闭。 当使用器具时,本发明的一些实施例使用GFCI技术继续提供接地故障保护。 所有这些都是自动快速执行的,在正常使用中几乎无法察觉。 一些实施例可以与外部控制系统集成。

    • A safety circuit used in low-voltage connecting systems leaves the two low-voltage systems disconnected until it determines that it is safe to make a connection. When the safety circuit determines that no unsafe conditions exist and that it is safe to connect the two low-voltage systems, the safety circuit may connect the two systems by way of a “soft start” that provides a connection between the two systems over a period of time that reduces or prevents inductive voltage spikes on one or more of the low-voltage systems. When one of the low-voltage systems has a completely-discharged battery incorporated into it, a method is used for detection of proper polarity of the connections between the low-voltage systems. The polarity of the discharged battery is determined by passing one or more test currents through it and determining whether a corresponding voltage rise is observed.

    • Current transformer relays having dual functions as current transformers and electromechanical switches are described. The current transformer relay includes a relay coil and a conducting loop concentric with the relay coil. Additional functions are thus provided in addition to the main relay switching function or functions. The concentric nature of the relay coil and the conducting loop create a current transformer between these elements. The additional functions include the ability to measure an alternating current (AC) current conducted by the conducting loop, the ability to detect and interpret an information signal imposed on power lines connected to the conducting loop, the ability to induce or impose an information signal on the conducting loop for transmission to power lies connected to the conducting loop, and the ability to measure a differential current between currents carried by the conducting loop and a second concentric conducting loop.
