Abstract: A system includes a power source, an electrical load, a pyrotechnic fuse, a pyrotechnic fuse, and/or an electrical subsystem, in some configurations. The load may be selectively electrically connected to the power source. The fuse may be electrically connected between the power source and the load. The subsystem may be electrically connected to the power source and the fuse. The subsystem may include a first circuit section, a second circuit section, and/or a capacitive coupler. The first circuit section may include a fault detector that detects faults associated with the power source. The second circuit section may include a fuse actuator. The capacitive coupler may be electrically connected to the fault detector and the fuse actuator. The capacitive coupler may isolate the first circuit section from the second circuit section. In accordance with detecting a fault, the subsystem may actuate the fuse to disconnect the power source from the load.

Abstract: A system comprises a bus and a capacitive circuit. The bus connects a battery and an impedance. The capacitive circuit is connected to the bus between the battery and the impedance. The capacitive circuit charges the impedance by using current from the battery and discharges the impedance by discharging current from the impedance through the capacitive circuit. The capacitive circuit comprises a primary switch bridge comprising a high-side switch and a low-side switch, a secondary switch bridge comprising a high-side switch and a low-side switch, and a capacitor connected between the switch bridges.

Abstract: A method of efficiently tracking state data on a computer by designating a class of items called watch objects which have relationships with other data that may change. A change in value in the data which a watch object relies upon causes the execution of a method which efficiently evaluates the watch object and other items which depend on the watch object.
