Patent number: 8371163Abstract: In some embodiments, a method for monitoring tropical storm conditions includes determining a target sea-surface path relative to a tropical storm center where in situ measurements are desired. A buoy is configured to include one or more sensors for one or more in situ measurements and to move relative to a local wind in the tropical storm so as to approximately follow the target sea surface path. The buoy is deployed in the tropical storm at a location substantively on the target sea surface path. In some embodiments, a buoy includes means for automatically maintaining position near a sea surface, moving at a particular direction and a particular speed relative to a local wind, measuring one or more environmental conditions in a vicinity of the buoy, and sending, to a remote facility, observation data based on output from the means for measuring one or more conditions.Type: GrantFiled: November 11, 2008Date of Patent: February 12, 2013Inventor: Marshall Delph Earle

Patent number: 8299931Abstract: An inexpensive and simple-to-operate ice safety device is provided for deployment in a body of water. Once deployed, the ice safety device can be activated to check whether ice has formed to a predetermined thickness around the ice safety device. If ice has not formed to the predetermined thickness, the ice safety device indicates an unsafe condition. The ice safety device can be moored to a fixed location.Type: GrantFiled: August 31, 2009Date of Patent: October 30, 2012Inventor: Zoe Eggleston

Patent number: 7536907Abstract: An illuminated rain gauge comprising an elongated, transparent collection vessel or tube having upper and lower ends with the lower end thereof being closed by a plug and which has a funnel-shaped collector at the upper end thereof. The plug has a battery compartment formed therein for receiving a DC battery power source. A pair of LEDs are operatively connected to the battery power source and are positioned on the plug outwardly of the vessel so as to direct light upwardly therefrom to illuminate the rain gauge. A third LED is positioned on the plug and is operatively connected to the battery power source so as to direct light upwardly onto the vessel and the float. The electronic circuitry of the gauge is positioned within the plug and is controlled by a remote IF control device which signals an IF receiver positioned on the plug.Type: GrantFiled: August 1, 2007Date of Patent: May 26, 2009Inventor: George W. Peterson

Patent number: 6789417Abstract: A magnetostrictive precipitation gage includes a catch tube having an upper opening configured to receive precipitation therein. A vertical magnetostrictive rod and corresponding magnetic float linearly displaceable thereon are used to determine the fluid level within the catch tube. More particularly, as the fluid level fluctuates in the catch tube, so will the vertical position of the float, which interacts magnetically with the magnetostrictive rod. Accordingly, the vertical position of the float may be detected to determine the fluid level within the catch tube, and calculations regarding precipitation may be performed.Type: GrantFiled: September 27, 2002Date of Patent: September 14, 2004Assignee: The United States of America as represented by the Secretary of AgricultureInventor: Charles H. Luce

Patent number: 6609422Abstract: A rain gauge includes a cylindrical rain holder having a float in the rain holder and a rainfall value indicator arranged so that as the float moves vertically in the rain holder a pointer moves circumferentially to indicate the amount of rainfall. A cover for the rain holder includes an opening that is less in area than the area of the surface of water in the rain holder, whereby the water level in the rain holder raises less than but in proportion to the rainfall. The pointer is on the float and the float is mounted to a vertical screw so as to rotate as it floats vertically, whereby the pointer points to lettering on the rain holder wall indicating the amount of rainfall. The pitch per inch of the screw is proportional to the ratio of the area of the surface of water in the rain holder to the area of the opening.Type: GrantFiled: December 8, 1999Date of Patent: August 26, 2003Inventor: Robert C. Geschwender

Patent number: 6401530Abstract: A rain sensor is described comprising a tray for the collection of rain water provided on top with evaporation and overflow side windows covered by a perforated cover. A finned float is housed in said tray so as to be able to move vertically as a function of the level of the water present in the tray. A permanent magnet supported by said float cooperates with an electric magneto-sensitive switch that is fixed to the tray in order to switch it between a first and a second electric state as a function of the vertical position of the float.Type: GrantFiled: February 17, 2000Date of Patent: June 11, 2002Assignee: Claber S.p.A.Inventor: Gianfranco Roman

Patent number: 6169487Abstract: A severe storm warning system includes an atmospheric pressure sensor utilizing an air-filled chamber with a first pressure sensor mounted between the interior of the chamber and the atmosphere and being located within the chamber interior and a second pressure sensor mounted between the interior of the chamber and the atmosphere and being located outside the chamber. Both sensors are formed of multiple-plate, floating plate capacitors which are movable in response to pressure changes. Electronic circuitry periodically determines what pressure changes have occurred and compares the changes to the changes associated with a predetermined signature of the type of severe storm being determined. Indicators including alarms are provided if a known sequence of pressure changes is detected.Type: GrantFiled: December 13, 1999Date of Patent: January 2, 2001Inventor: Robert B. Davis
