Abstract: A device for generating a controlled flow event to regulate a hydraulic condition of a piping system of a building is an electrically-powered fluid pump or fluid valve, having a fluid inlet and fluid outlet. The fluid inlet is configured to be in fluidic communication with a tank of a toilet or is supplied water from the piping system of the building. The fluid outlet is in fluidic communication with either: i) a bowl of the toilet; ii) an overflow tube of the toilet tank; or iii) the tank of the toilet; iv) or a drain. An electronic controller controls the operation of the device and is configured to repeatedly turn on and off the electrically-powered fluid pump for a predetermined elapsed time when the hydraulic condition is identified. The hydraulic condition may be a potential freezing condition or an overly high pressure of the piping system of the building.

Abstract: Fluid cooled electric vehicle battery systems are disclosed. Systems can include an integrated coolant manifold and bus bar configured to carry coolant and electrical current along a common or coaxial path. An integrated coolant manifold and bus bar can include a conductive layer surrounding a coolant flow path and/or a conductor disposed within a coolant flow path. Integrated coolant manifold and bus bar structures may improve efficient use of battery space by reducing the number of battery components and by allowing reduced bus bar size due to fluid cooling of the bus bar.
