    摘要: A dc-to-coax adapter is provided for establishing an electrical coupling between a power source and a coaxial cable device. The adapter may include a power connector portion and an RF connector portion. In an exemplary embodiment the power connector portion comprises a dc jack adapted to establish an electrical coupling with a standard dc barrel plug connector and the RF connector portion comprises a female F connector adapted for establishing electrical coupling with a male F connector. The contacts of the power connector portion may be integrated with the contacts of the RF connector portion the adapter housing may provide a continuous ground connection.

    摘要: The present invention is directed towards a discrete protection circuit located on a circuit card, and systems and methods related thereto. The protection circuit protects circuit card components from an inrush current and overcurrent conditions. The discrete protection circuit includes a switch to control a delivered load current to an output port, an SCR which latches when an overcurrent condition is detected across a sense resistor, and a series of resistors and a capacitor that determines the retry delay subsequent to an overcurrent detection. Advantages of the discrete protection circuit of the invention over prior art integrated circuits include: lower parts counts, lower production costs, greater flexibility, and increased reliability.

    摘要: A power supply system that provides redundant power by automatically selecting one power supply as the master power supply. Power supplies configured in parallel share load. The load voltage of the power supply is compared to a reference voltage producing output errors. The error is amplified and compared with the peak switch currents to determine the pulse width of the power supply switch. The power supply with the highest error voltage controls a shared bus and thus become the master. The remaining power supply (or power supplies) having a lower error voltage becomes (or became) the slave power supply. Thus, the system automatically provides redundancy with one power supply operating as the master and the remaining ones as the slave power supplies. Due to the common shared bus, all the paralleled power supplies have the same peak currents through their switch and to the load. In an alternative embodiment, one power supply can be pre-set as the master power supply with the remaining power supplies functioning as slave power supplies.
