A facility wayfinding system is provided which includes an interactive public display device and a mobile device, running a mobile wayfinding application. The interactive public display device, which is situated at a first location within a facility, displays a facility map showing facility units, receives a user selection of a facility unit as a second location, and displays a route from the first location to the second location on the facility map. The mobile device also displays the facility map, displays a route from a start location to a destination location on the facility map, and updates the start location to the first location and the destination location to the second location by synchronizing with the interactive public display device.

A power distribution network includes multiple charge storage components and multiple charging circuits to control the charging and discharging of the charge storage components, which may comprise a battery and a supercapacitor. By appropriate arrangement and selection of the storage components, ripple in the power supply voltage, whose propagation to other components relying on the power distribution network may cause an audible buzz, may be significantly reduced. Additionally, appropriate arrangement and selection of the storage components, electromagnetic interference may also be significantly reduced. Optionally, an electromagnetic interference filter may be placed between the charge storage components.
