Patent number: 7772579Abstract: Particle detection systems without knowledge of a location and velocity of a particle passing through a volume of space, are less efficient than if knowledge of the particle location is known. An embodiment of a particle position detection system capable of determining an exact location of a particle in a fluid stream is discussed. The detection system may employ a patterned illuminating beam, such that once a particle passes through the various portions of the patterned illuminating beam, a light scattering is produced. The light scattering defines a temporal profile that contains measurement information indicative of an exact particle location. However, knowledge of the exact particle location has several advantages. These advantages include correction of systematic particle measurement errors due to variability of the particle position within the sample volume, targeting of particles based on position, capture of particles based on position, reduced system energy consumption and reduced system complexity.Type: GrantFiled: May 18, 2007Date of Patent: August 10, 2010Assignee: Massachusetts Institute of TechnologyInventors: William D.

Patent number: 7543493Abstract: A cylindrical collector of the rain gauge has a vertical distinctively colored stripe extending parallel to its vertical axis a focal length from its central axis on the opposite side of the rain gauge from rainfall indications. With this arrangement, the rain water in the rain gauge appears to have the color of a stripe which makes the water height easier to see. An open end of a parallelopiped interface receives the rain and has an area larger than the cross sectional area of the cylindrical collector to which it supplies the rain it receives. The numerals on the rain gauge indicating rainfall are scaled in proportion to the ratio of the area of the open end of the interface and the cross sectional area of the cylinder for easier reading. The parallelopipe design was selected to reduce the size of the shipping container and the dimension perpendicular to the holder is less than the width to permit the gauge to lie flat against a surface for hanging.Type: GrantFiled: March 14, 2007Date of Patent: June 9, 2009Inventor: Robert C.

Patent number: 7516002Abstract: A system and/or method for sensing the presence of moisture (e.g., rain) and/or other material(s) on a window such as a vehicle window (e.g., vehicle windshield or backlite). In certain example embodiments, a capacitor-based system and/or method is provided for auto-correlating sensor data to determine the existence of a material on the window, and then cross-correlating sensor data to identify the type and/or amount of that material (e.g., rain). This data may be used to actuate and/or deactivate a vehicle's wiper(s), and/or adjust wiper speed. In certain example embodiments, the sensor may include an array of at least two capacitors. In certain example embodiments, the system and/or method may perform check(s) to enhance the accuracy of the detection by comparing, for example, the sign of autocorrelation values, maximum autocorrelation values, and/or gradients of autocorrelation values.Type: GrantFiled: January 27, 2006Date of Patent: April 7, 2009Assignee: Guardian Industries Corp.Inventor: Vijayen S.

Publication number: 20080110254Abstract: A dual channel inflight ice detection system to detect ice accretion on an aircraft surface by illuminating an ice collecting surface mounted on an aircraft with linear polarized light. The backscattered light is acquired in two light conductors one with polarization sensitivity aligned to the transmitted light and the second with polarization sensitivity orthogonal to the first. The presence of ice is determined by the change in the ratio of light intensities in the two light conductors.Type: ApplicationFiled: October 31, 2006Publication date: May 15, 2008Applicant: SWAN INTERNATIONAL SENSORS PTY LTDInventors: Dong Zhao, Paul Andel, Brian McGuire

Patent number: 7340949Abstract: A precipitation measurement device measures a precipitation rate of falling precipitation. A first probe is exposed to the falling precipitation. A first temperature sensor detects a first probe temperature. A second probe is shielded from the falling precipitation. A second temperature sensor detects a second probe temperature. A heating element heats the first probe and the second probe when turned on, but not when turned off. After being heated and when the heating element is turned off, the first probe cools at a first temperature drop rate, and the second probe cools at a second temperature drop rate. Circuitry processes a difference between the first temperature drop rate and the second temperature drop rate to determine the precipitation rate of the falling precipitation.Type: GrantFiled: November 8, 2006Date of Patent: March 11, 2008Assignee: University Corporation for Atmospheric ResearchInventor: Frank William Hage

Patent number: 6883390Abstract: A system measures dynamic force of an impacting spray of air and water. A pitot-tube section is aligned to receive a longitudinal flow of impacting air/water spray in a laterally extending orifice. A first differential pressure transducer is coupled to the pitot-tube section for producing signals representative of velocity of the air/water spray at the orifice. A rain gage section adjacent to the pitot-tube section receives and collects volumes of water of the longitudinal flow of air/water spray through a laterally extending opening. A second pressure differential transducer is coupled to the rain gage section to produce signals representative of the volumes of water collected in the rain gage section. A computer-based control/readout module receives the velocity representative signals and water volume representative signals for indicating the magnitude of dynamic force attributed to impacting air/water spray in the opening.Type: GrantFiled: December 18, 2003Date of Patent: April 26, 2005Assignee: The United States of America as represented by the Secretary of the NavyInventor: Richard A.

Patent number: 6751571Abstract: A precipitation measuring system comprising a top thermal plate positioned to maximize exposure to falling precipitation and includes at least one ridge circumscribing the top surface for capturing precipitation. A second thermal plate is positioned under the top thermal plate to protect it from falling precipitation while still exposing it to the same atmospheric temperature and wind conditions.
