    Abstract: 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 or low-voltage systems, the safety circuit may make the connection by way of a soft start that provides a connection over a period of time that reduces or prevents inductive voltage spikes. 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.

    Abstract: A surge protection element (50) for a conventional cable connector (10) includes a printed circuit board (50) preferably shaped as two concentric rings (58,54) connected by two spokes (56,57). The outer ring (54) is electrically connected to the grounded portion of the cable connector body. A printed circuit trace (62) on one of the spokes is separated from a printed circuit trace (66) on the inner ring (58) by a spark gap. If a high voltage surge is carried by the coaxial cable transmission line, a spark is formed in the gap. As a consequence, the high voltage surge is transferred to the surge protection element (50) which in turn conducts the electricity to the grounded body of the connector (10).

    Abstract: A power supply device capable of preventing a drive transistor from being damaged by heat when a collector output is grounded. A power supply device (10), which supplies for driving a drive current to the base of a transistor (20), has a lower-limit threshold value comparison unit (14) for comparing an actual collector output Vin with a lower-limit threshold value 0.5Vref of the transistor (20), and, when the collector output Vin is less than the lower-limit threshold value 0.5Vref, issuing a stop signal to a current control unit (18). Therefore, since the collector output of the transistor (20) grounding without intermediary of a load circuit (40) lowers the collector output Vin below the lower-limit threshold value 0.5Vref, the current control unit (18) receives a stop signal from the comparison unit (14) to stop the supply of a drive current to the transistor (20), thereby preventing damage to the transistor (20) by heat.
