Filed:

Oct 29, 1997

Appl. No.:

8/960347

Inventors:

Eugene T. Smith - Alexandria VA

Assignee:

Estech Corporation - Annandale VA

International Classification:

G08G 100

US Classification:

340902

Abstract:

A low-cost and reliable radio warning system that alerts system users of potential hazardous conditions is disclosed. The system makes use of a transmitter and at least one receiver. The transmitter generates and transmits a radio warning signal that carries a digital data sequence that includes information concerning a particular potential hazardous condition from which the transmission was initiated, such as an approaching ambulance, fire truck, bus, train, or the like. Other information, such as GPS coordinates, may also be included. Through the use of digital encoding techniques, the system's susceptibility to false alarms or "false triggers" is minimized. The radio warning signal is transmitted in burst transmissions and may use a number of signaling techniques, including spread spectrum transmission, which increases system reliability and performance even in the presence of interference or multipath distortion. System users are equipped with a receiver that receives the radio warning signal and interprets the digital data and information carried by the warning signal. The receiver alerts the system user who has received the radio warning signal of the potential hazardous condition through the use of an audible, visual or tactile alarm.

Abstract:

An automatic water sprinkler assembly is provided. A main conduit is connected to a source of water pressure, at least a portion of the main conduit is buried underground with a releasably connected vertical portion extending above ground. A main horizontal feeder conduit having at least four vertical output conduits is connected to a source of electrical power for operating electrically controllable valves associated with each of said at least four vertical output conduits for selectively controlling fluid flow therethrough. Each of the four vertical output conduits has an end portion terminating above ground and releasably connected to a primarily horizontally extending discharge conduit. The vertical portion of the main conduit, the horizontal feeder, and the vertical output conduits are all releasably connected above ground so that the entire distribution assembly is portable. Alternatively, the valves may be manually operated.
