Publication number: 20230314299Abstract: Systems and methods for trapping and holding airborne particles using an orienting hollow beam are disclosed. In the various embodiments, an optical trap comprises: a light source for generating a beam of light; optics and/or mechanics for forming and shaping the beam of light into an orienting hollow beam having unequal axisymmetry with a substantially hollow ring geometry cross-section and no angular momentum; an optical focusing element for focusing the orienting hollow beam; and a trapping region where an airborne particle can be present to be trapped and held at or near a focal point of the focused optical focusing element. In this arrangement, the particle is trapped at or near the focal point of the focused orienting hollow beam. In this arrangement, the particle is trapped at or near the focal point of the focused orienting hollow beam.

Patent number: 10859694Abstract: The invention describes a method of monitoring of increased risk of lightning on the basis of information about the increase of electric charge of water droplets, which are obtained by measuring the characteristics of scattered EM radiation. The change of these characteristics is related to the electric charge, which the droplets acquire. In order to normalize the optical characteristics as well as the concentration of droplets it is necessary that the measurements are carried out at two suitably selected wavelengths. The wavelengths can be combined, allowing the use of two or more wavelengths.Type: GrantFiled: December 19, 2014Date of Patent: December 8, 2020Assignees: USTAV STAVEBNICTVA A ARCHITEKTURY SAV, UNIVERZITAKOMENSKEHOBRATISLAVEInventors: Gorden Videen, Miroslav Kocifaj, Jozef Kla{hacek over (c)}ka

Patent number: 9116838Abstract: Systems and methods for calculating the Lyapunov exponent of a chaotic system are described. In one particular embodiment, a Lyapunov exponent calculating method includes obtaining a value indicative of a condition of a chaotic system and assigning the value to first and second precision levels, the second precision level having a higher level of precision than the first precision level. The method also includes iterating the chaotic system over time and comparing the value at the first precision level with the value at the second precision level. From the comparison of values at the first and second precision levels, the method calculates the Lyapunov exponent for the chaotic system.Type: GrantFiled: April 8, 2011Date of Patent: August 25, 2015Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Gorden Videen, Robert H Dalling

Patent number: 7355707Abstract: A system and method and for analyzing dew in a system of interest are provided. A representative method comprises receiving infrared information corresponding to a degree of polarization of dew in a particular environment, and using the degree of polarization to determine dew presence in the environment. Changes in the degree of polarization can be attributed to changes in the density, size or shadowing of the dew drops. Infrared emissions information can be detected and accumulated over a range of emission angles and over a period of time. The system compares the accumulated data for the particular environment to detect the presence of dew, the rate of growth of the dew and the change in characteristics of dew over a period of time starting from a first time interval. The system also compares the accumulated data with other previous accumulated data from the environment to detect if changes should be made to the environment.Type: GrantFiled: September 9, 2005Date of Patent: April 8, 2008Assignee: The United States of America as represented by the Secretary of the ArmyInventor: Gorden Videen
