摘要： An off-mains switch (14) and a control box (15) for electrically adjustable articles of furniture, such as beds, chairs or tables, which automatically interrupt the connection to the power supply when the article of furniture is not adjusted, such that this will not constantly be under the mains voltage. These off-main switches require a multi-part cable which is rigid and thick. In the present structure (14, 15) a single two-part cable (13) is sufficient, as the off-mains switch (14) is configured such that the control signals between control unit/control box (15) and the off-mains switch are transmitted through a mains cable (13). A standard cable having two conductors is then sufficient. This means in turn that standard plugs may be used, and thus that the cable (13) may be connected to the power supply via an ordinary plug. Since, hereby, the off-mains switch may appear as a separate unit, production and logistics are facilitated.

摘要： 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.

摘要： A battery protection circuit for an external battery pack has a switch for controlling connection of a battery output to a load and a detector for detecting a resistance at a load output terminal. A first comparator compares the detected resistance to a predetermined maximum value, and a second comparator compares the detected resistance to a predetermined minimum value. If the detected resistance is in the range between the minimum and maximum values, a control signal is produced to enable connection of the battery output to the load. If the detected resistance is outside the range, the switch is disabled and no current can flow to the load.

摘要： A coaxial drop cable safety device is used for cable television, data and telephony applications. The device is used on buried drop cable where 60 Hz powering voltages applied to the drop cable exceed low voltage safety limits and where the drop cable is buried at depths which is less than the minimum required to meet electrical safety codes. Tap end and premise end units are connected to the drop cable. The tap end unit applies a DC voltage to the center conductor of the drop cable. A monitoring circuit in the tap end unit monitors the center conductor DC voltage to a fault from the center conductor to ground along the drop cable. The tap unit will immediately remove the powering voltage In the event of either an open or faulted condition on the center conductor along the entire length of the drop cable. Additionally, while providing fault protection for the low frequency powering circuit due to tampering or damage to the cable, the fault monitoring circuit allows the high frequency television, data and telephony signals to pass with little or no impediment.

摘要： A power supply circuit for a neon tube includes a step-up power transformer having a primary winding connectable to a power source, a secondary winding to which the neon tube is connected, and an auxiliary winding which is used to sense if the secondary winding is loaded or not and develops a control voltage proportional to current flowing through the neon tube, the control voltage maintaining a relay operated so that the primary winding of the transformer is connected to the power source in the absence of load fault conditions, a load fault condition causing the control voltage to decrease below the level required to maintain the relay operated, so that the primary winding of the transformer is disconnected from the power source, interrupting high voltage in the secondary winding of the transformer.

摘要： A low impedance load is switched between a power supply source and ground through a series connected power MOSFET the conduction of which is controlled by a switching circuit. The switching circuit includes a linear loop that regulates the switch voltage to a minimum value to produce current flow through the load and the MOSFET. In addition, the switching circuit includes a current supply placed in parallel to the MOSFET which is set to supply a minimum predetermined current that is representative of the value of current flow through the load under an open load condition. If the load current falls below this set current value an open load status flag is provided by the switching circuit as the loop is no longer in regulation.

摘要： A resonant L-C circuit is series-excited from an AC voltage source and intended to be parallel-loaded with a load that, for some reason or another, may be inoperative. For efficiency reasons, the unloaded circuit Q-factor may be about 50 times higher than the loaded Q-factor; which implies that, if the load were to become inoperative, the power drawn by the L-C circuit from the source, and the voltage/current magnitudes developed in the L-C circuit, would be 50 times larger than when the load is operative. To prevent unnecessary power drain and/or to avoid damage to source and/or circuit components, which damage may occur even if the L-C circuit is left unloaded for but a very brief period, a circuit protector is provided.This circuit protector comprises: (i) a Varistor to provide an absolute limit on the maximum attainable magnitudes of power, voltage and current, such as to protect protecting the source and the L-C circuit, and (ii) control arrangement operative to protect the Varistor from overloading as well as to prevent unnecessary power drain, which control arrangement provides for an intermittently interrupted short circuit across the tank-capacitor in case current flows through the Varistor for more than a very brief period of time. With the tank-capacitor shorted, the resulting power drawn from the source will be of negligible magnitude.

摘要： A power supply system comprising an a.c. voltage source (ACS), a load (LL) and a detachable (DCC) cable connection (CC). In order to prevent a dangerously high a.c. voltage from occurring between cable conductors (CC1, CC2) when the cable connection is loose, a safety circuit (CITSR) is provided which includes an on/off switching circuit (S1, SR1, S2, SR2). The safety circuit (CITSR) includes a parallel arrangement (CI) of at least one capacitor (C) and a direct current source (I). The parallel arrangement (CI) is part of a direct current circuit (CC2, DC2, CC1, S1, DC1, CC2) which is closed via the cable conductors (CC1, CC2), the a.c. voltage source (ACS) and the load (LL). The parallel arrangement (CI) is coupled to the on/off switching circuit (S1, SR1, S2, SR2) via a threshold circuit (TC). When a controllable a.c. voltage source (ACS) is used to produce a low voltage (30 V) before a high voltage (700 V) is supplied, it is first detected whether there is a high-ohmic load or a short-circuit between the cable conductors.
