Portable ultrasound system with battery backup for efficient shutdown and restart |
摘要 |
An ultrasound system is described which can be turned off quickly by an operator command or in response to an interruption of a.c. power to the system. When a.c. power is cut off, the system switches to battery backup while a processor executes an orderly shutdown sequence. The system can completely shut down, or the state of the system can be minimally preserved by battery backup in either volatile or nonvolatile memory so that the system can restart without having to sequence through an entire bootup procedure. This enables the system to remain active even when the ultrasound system is unplugged and being moved.
