Abstract: Systems and methods for monitoring and controlling water consumption in a water-based system are disclosed using one or more sensors for generating signals indicative of the operation thereof. One or more interface modules are provided as breaker circuits for receiving the generated signals, and a fluid control device is operable for limiting the water consumption. A motherboard receives the interface modules and provides communication therebetween for information processing. Signals from the various sensors are supplied to a controller, which provides signals to status indicators, and also operates to provide alarm signals via network interfaces to remote locations and to operate an alarm. In an alternate embodiment, a water monitoring system is designed to shut off the water supply to the water device and to shut off either the electrical supply or the gas supply to the heating unit of the water device in response to sensing a malfunction through one or more of a number of different sensed parameters.

Abstract: A swimming pool alarm system includes a sensor device mounted at the water line of the pool and carrying a magnetically actuated, normally closed switch and a magnet carried by a float for maintaining the switch closed when the water is at a predetermined level whereby the switch closes if the float moves downwardly away therefrom in response, for example, to lifting of the device out of the pool or from wave motion of the water in the pool.

Abstract: A set of electric terminals are mounted in a vehicle near the end thereof opposite to the end where the battery is located and are connected internally of the vehicle to the battery terminals thereby to permit jumping of the battery from either the front or rear end of the vehicle.
