After the current-use system is switched to the standby system, the standby system executes processing using the notification data stored in the memory of the standby system.

The electrical system may involve induction while the mechanical system may involve a solenoid or fully mechanical arrangement, the mechanical system acts as a backup for the electrical system if required.

The ENUM-DNS includes a master system and a standby system.

The main subsystem is in fluid communication with the emergency subsystem.

The system includes a fault ride through system having a variable resistor and a variable inductor.

During emergency mode, the emergency subsystem is configured for independently providing fluid to the working element.

Said primary/ standby dual-active systems comprise a primary system and a standby system, both capable of becoming either a source end or a destination end.

A fluid system includes an emergency subsystem and a main subsystem in fluid communication with a working element.

The invention also relates to a backup system and a computer program product.

Disaster Recovery (system protection and recovery)

Electric or fuel backup can be used with this system to regenerate the desiccant material.

A traffic light backup system for use with a traffic light is described.

The authentication information is associated with an identifier of the wireless backup system.

In some situations, a secondary or backup system is required.

It was great to finally have a support system of my own.
