“Controller for Life Support Device and Control Method Thereof” describes a controller that communicates with parts of a life-support device through a first interface and uses a second interface to maintain an output state until it receives a specified data sequence again. This arrangement allows a device component to be driven through the second interface.

“Medical Device and Method for Controlling Same” describes a medical device with a primary controller and a backup controller that operates if the primary controller fails. An alarm notification is determined using the exclusive OR of their notification outputs. The backup controller adjusts its output according to whether the primary controller’s notification is on or off.
