Abstract: A method and apparatus worn by a user for controlling weeds using concentrated solar energy is disclosed. Solar energy may be concentrated by Fresnel lens over the wearer and directed by manual methods by the wearer at surfaces of weed plants to heat portions thereof causing damage. Shutters or other devices may be used to direct, and control intensity of concentrated, solar energy, such control preferably applied before significant concentration of the solar energy. In some embodiments, solar energy concentration apparatus may be integrated with solar photovoltaic cells for generating electric power for purposes such as an electrical temperature sensor, a camera and video display device for viewing underneath a crop canopy, control of solar intensity and other purposes.

Abstract: A method and apparatus for controlling weeds using concentrated solar energy is disclosed. Solar energy may be concentrated by Fresnel lens and directed by manual or automated methods at surfaces of weed plants to heat portions thereof causing damage. Shutters or other devices may be used to direct, and control intensity of concentrated, solar energy, such control preferably applied before significant concentration. In some embodiments, solar energy concentration apparatus may be integrated with ground, air, or water vehicles which may use solar photovoltaic cells for electric power for propulsion and other purposes. Vehicles may use global positioning satellite (GPS) receivers or other methods and apparatus, including video cameras, for navigation and selection of areas (e.g., row middles), plants, or portions of plants to be exposed to concentrated solar energy. Air vehicles may use hydrogen gas electrolyzed from water condensed from humid air to replenish hydrogen gas lost from containment vessels.

Abstract: Apparatus and methods for an airborne biota monitoring and control system are disclosed. Radar and laser/optical sensors are used to detect insects, with detection zones being over water in some embodiments to reduce backscatter clutter. A pest control laser or small autonomous or radio controlled aircraft under automated or human control may be used to disable a targeted flying insect. Technologies include radars formed using semiconductor modules, such as are being developed for automotive radar and other industrial applications. Also disclosed are additional embodiments of the instant invention.

Radar and laser/optical sensors are used to detect insects, with detection zones being over water in some embodiments to reduce backscatter clutter. A pest control laser or small autonomous or radio controlled aircraft under automated or human control may be used to disable a targeted flying insect. One embodiment includes use of a head-mounted display for displaying insect targeting information superimposed on a real landscape view. Technologies such as adaptive lens, holographic optical elements, polarized radar and/or laser beams, light amplifiers and light guides, thin disk, spinning disk, or vertical cavity surface emitting lasers enhance performance of the apparatus or reduce cost of the apparatus. Also disclosed are methods of discrimination of insect types using spectral information and dynamic relative variation of spectral intensities at different wavelengths reflected from an insect in flight.

Abstract: A method and system, which may be implemented in some embodiments as a video game, for identifying harmful airborne biota, particularly flying insects, and either killing or disabling the harmful airborne biota is disclosed. Lasers, radar, and other types of radiation may be used to illuminate objects in a detection region, with radiation returns detected and applied to a pattern classifier to determine whether the detected airborne biota are harmful, benign or beneficial. Tracking and classification information may be provided to a remotely located game participant who may be permitted to control measures taken to eliminate the harmful airborne biota, these measures including firing pulses of beamed energy or radiation of a sufficient intensity to at least incapacitate them, or mechanical measures such as flying a remotely-controlled miniature unmanned aircraft to engage and kill the pests.

Abstract: A method and system for identifying harmful airborne biota, particularly insects, and including plant material, such as mold spores and pollen, and flying insects and birds and either killing ordisabling the harmful airborne biota is disclosed. Lasers, radar, and other types of radiation may be used to illuminate at least a perimeter around assets to be protected, with radiation returns detected and applied to a pattern classifier to determine whether the detected insects of interests are harmful, benign or beneficial. In the event the insects are determined to be harmful, a variety of measures responsive to the radiation returns may be taken to eliminate the harmful insects, these measures including firing pulses of beamed energy or radiation of a sufficient intensity to at least incapacitate them, or mechanical measures such as controlled drone aircraft to track and kill the pests.

Abstract: A method and system for detecting airborne plant material, such as mold spores and pollen, and flying insects and birds, and classifying them as to whether they are harmful to field crops, production animals or other assets within a protected volume or area. Lasers, radar, and other types of radiation may be used to illuminate at least a perimeter around such assets to be protected, with radiation returns detected and applied to a pattern classifier to determine whether the detected objects of interest are harmful, benign or beneficial. In the event the objects are determined to be harmful (pests), a variety of measures controllable via the radiation returns may be taken to eliminate the harmful objects, these measures including firing pulses of laser, microwave or other radiation of a sufficient intensity to at least incapacitate them, or mechanical measures such as controlled drone aircraft to macerate the pests with propellers or spray limited amounts of pesticide in the area of the pests.

Abstract: A method for processing an image of eyes of a subject is provided. The image is divided into two halves, each containing an eye of the subject. The halves are then processed to determine at least a position of a pupil within the first half and second half. After positions of the pupils are determined, horizontal and vertical histograms are developed from the pupil in each of the halves. Several ways of plotting the respective histograms are disclosed, these plots provided with various indicators for detecting abnormal conditions of the eyes.

Abstract: A plurality of methods of analysis of images of eyes of a subject taken by a reflex photometer are disclosed. In this methods, a computer coupled to the reflex photometer is programmed to locate the pupil of at at least one eye, crop an image array containing the pupil from the total image and perform analyses on the cropped array to determine whether conditions are present indicative of disease processes in the eye. In essence, parameters of the subject eye are developed, and these subject pararmeters are compared to the same parameters developed by a normal eye. In addition, indications of strabismus are examined by comparing the area of the white portion of the eye on one side of the iris with the white portion on the other side of the iris.
