According to one embodiment, a power control circuit includes a converter, a signal generating circuit, an estimation unit, and a controller. The converter includes a switching circuit and is configured to transform an output voltage from a power generator. The signal generating circuit is configured to transmit a signal to the switching circuit. The estimation unit is configured to determine a switching operation condition based on vibration information indicative of a vibration applied to the power generator. The controller is configured to control an operation of the switching circuit based on the determined switching operation condition.

An intelligent fuseless switch includes a moving contactor, a switch, a base, and a vibration detection module. When the vibration detection module detects that vibration intensity is higher than a preset value, the electromagnetic trip device is triggered by the base to push the moving contactor to open a circuit. The power cannot be introduced into the house. This automatic power-off mode has an active protection effect. After the vibration detection module is installed, if it needs to be repaired, it can be directly replaced without removing the circuit breaker, thereby reducing the difficulty of maintenance greatly.

A system and method for protecting an electronics module on a spacecraft in space are described. The system includes a non-radiation hardened electronics module electrically connected to a power supply, with a switch connected between the power supply and the electronics module. The switch can disconnect the electronics module from the power supply in response to an event signal. A sensor which is capable of detecting a solar proton event is connected to the switch. The sensor emits the event signal upon detection of the solar proton event.

A communication device has a first data interface and a second data interface. A safe protection of the communication device against malicious code even under an easily breakable communication line between the communication device and a remote server is achieved by an intermediate protection unit located in a data communication line between the two data interfaces, wherein the intermediate protection unit blocks data in the direction from the second to the first data interface.

A protective device includes an airbag assembly configured to extend at least partially around a waist or hips of an individual; a buckle attached to the airbag assembly, the buckle comprising a first buckle half, and a second buckle half, the first and second buckle halves being attachable to and detachable from one another; and an airbag actuator configured to actuate the airbag assembly. At least a portion of the airbag actuator is disposed in the first buckle half or the second buckle half.
