Filed:

Feb 27, 2008

Appl. No.:

12/038151

Inventors:

Barth Robins Pitchford - Fairfax VA, US
William Dudley Pitchford - Fairfax VA, US
Robert Paul Simon - Fairfax VA, US
C. David Binning - Warrenton VA, US
David Lewis Rasmussen - Vienna VA, US

Assignee:

Fairfax County Water Authority - Fairfax VA

International Classification:

F03B 13/00
H02P 9/04
H02P 15/00
H02K 49/02

US Classification:

290 43, 290 54, 310103, 310105

Abstract:

A system and method for generating and harvesting energy in response to the flow of water through rotating device, such as a nutating or oscillating disk. Mechanical energy from flow of water is converted into electrical energy via an energy conversion unit. For example, the power generation system may be used to power electronic and mechanical devices used in automated meter reading (AMR) systems. The power generator system may recharge a storage circuit that enables long term AMR operations without the need for battery replacement. The power generation system, in various embodiments, can provide additional power for two-way communication and other sensors such as pressure, temperature, water quality and services such as remote shut-off, event-based messaging, and water quality monitoring.

International Classification:

G08C 15/06

US Classification:

34087002, 34087007, 73195, 7386177, 7386178

Abstract:

A remote water meter monitoring system is provided. A mesh network-type transceiver unit is coupled to a water meter housing having a water counting mechanism inside to transmit water consumption information as well as other sensor information, such as backflow detection, water pressure, and water metrics (e. g. , residual chlorine and temperature) to a central server system via a bridge device and a corresponding mesh network. Mechanical energy from the water flowing through the water meter housing is converted to electrical energy via an energy conversion unit. An electrically powered shut off valve is remote addressable via the transceiver unit.

International Classification:

D02J 1/18

US Classification:

028282000

Abstract:

A large-tow fiber placement system having (1) a creel, (2) a tow feeding mechanism, (3) a tow cutting mechanism, and (4) a tow consolidation system, wherein the creel shuttles a spool to maintain a substantially fixed exit path of a large-tow exiting the spool, the tow feeding mechanism has a head that is cooled by a fluid to control integrity of the large-tow and the tow consolidation system has interlocking shoes to provide a continuous application of the head is disclosed.
