Ambulance is one the most critical component in healthcare where it must have highest reliability and mobility to ensure minimum travel time of patient to the hospital. In Malaysia, there are significant number of cases where ambulance tend to have breakdown or caught on fire due to electrical current overload which caused by unmanaged electrical usage by medical equipment. To overcome this problem, a smart power management system has been developed by employing Hall-Effect based current sensor replacing conventional fuse. The sensor reading is actively analysed by a microcontroller which will cut off electrical power from over-current equipment. The system also can prioritize some critical equipment to be powered when there are limited current available.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
