Abstract: A synchronization system for motor vehicles which enable external blinking or flashing lights of one or a number of vehicles to be synchronized. Among a group of motor vehicle, such as those produced by a given motor vehicle manufacturer, when the operators of the vehicles activate the turn signals or emergency flashers, they blink in unison with one another. External timing signals are used to establish the phasing of the flashing or blinking oscillations.

Abstract: An improved hot water supply system is disclosed which provides hot water from a faucet without requiring water flow for a prolonged period of time necessary to displace water retained within connecting pipe. A significant reduction in the time delay before hot water becomes available is achieved by employing a pair of hot water supply pipes connected to a valve or a flow controller. One of the pipes has an internal diameter which is less than that necessary to provide the maximum flow rate capacity requirement of the outlet. This small diameter pipe, termed the auxiliary pipe, is used to provide hot water when the valve is set at a low flow rate setting and due to its small retained volume, provides hot water quickly. A high flow rate setting, water flow through both a primary and auxiliary pipe is permitted, thereby enabling water to be discharged at the desired maximum flow rate various embodiments disclose alternate means for employing several hot water supply pipes.
