  • Publication number: 20190307117
    Abstract: An avian collision avoidance system utilizing a lighting system and a power source. The lighting system is able to focus on a power line, or power lines, or other structure such as a wind turbine or cell tower, to provide illumination visible to avian populations. The power source may generate power by any means necessary, may store power and may supply power to the lighting system. The lighting system will provide a light source in a desired wavelength to accommodate both humans and birds as necessary.

  • Patent number: 10345267
    Abstract: A method of detecting material changes in a composite structure is presented. A pulsed laser beam is directed towards the composite structure comprised of a number of composite materials. Wide-band ultrasonic signals are formed in the composite structure when radiation of the pulsed laser beam is absorbed by the composite structure. The wide-band ultrasonic signals are detected to form data. The data comprises a number of ultrasonic A-scans. The data is processed to identify a plurality of frequency measurements for each of the number of ultrasonic A-scans. A frequency image is displayed using the plurality of frequency measurements. The material changes are represented in the frequency image.

  • Patent number: 10309893
    Abstract: A method of detecting inconsistencies in a composite structure is presented. A pulsed laser beam is directed towards the composite structure comprised of a number of composite materials. Wide-band ultrasonic signals are formed in the composite structure when radiation of the pulsed laser beam is absorbed by a surface of the composite structure. The wide-band ultrasonic signals are detected over a duration of time to form data. The data comprises an ultrasonic A-scan spectrum. The data is processed to identify a structure signal in a frequency domain of the ultrasonic A-scan spectrum. The structure signal of the ultrasonic A-scan spectrum is compared to a structure signal of a composite structure standard to determine whether the inconsistencies are present in the number of composite materials.

  • Patent number: 10201815
    Abstract: The present disclosure provides for a novel pig design and method of retrieval based on thermal ablation. The pig comprises an external layer and an inner core, where the inner core further comprises at least one incendiary charge comprising at least one exothermic material. When ignited via an ignition source, the incendiary charge releases the exothermic material into one or more thermal dispersion channels. The exothermic material melts the interior of these thermal dispersion channels thereby distributing the exothermic material throughout the pig device causing its destruction via thermal ablation. The destroyed pig can then be easily retrieved from its location in a pipe, as detected via radio signals, without the need for costly excavation of large sections of the pipe.

  • Patent number: 8101551
    Abstract: A process and method for the production of endophytes as plant inoculant products, specifically Clonostachys rosea strain 88-710, for the promotion of plant vigor, health, growth and yield are disclosed. The endophyte, Clonostachys rosea strain 88-710 produces a fungal conidial preparation by utilizing a discrete solid substrate fermentation system, namely Potato Dextrose Agar or Malt Extract Agar. Additionally, the endophyte, Clonostachys rosea strain 88-710, can act as an inoculant to stimulate and have an additive effect with rhizobium bacteria on the production of nitrogen fixing nodules on legumes and growth enhancement e.g. beans, soybeans, peas and alfalfa. As well, Clonostachys rosea strain 88-710, can combine with rooting hormones, e.g. indole-3-butyric acid (IBA) to provide inoculant and rooting benefits to cuttings/transplants of plants.

  • Publication number: 20090047378
    Abstract: A feed/food process and product that provides a stabilized feed/food supplement that enhances the conversion efficiency and levels of omega 3 essential fatty acids including docasahexaenoic acid (DHA), Docosapentanenoic acid (DPA) and eicosapentenoic acid (EPA) in livestock/human products therefrom e.g. poultry. Specifically, Chickens (var. Ross) are fed a stabilized form of non-marine, non algal source omega 3 fatty acids including DHA, EPA, DPA for 5 weeks during a total 6 week production period that results in conversion efficiencies and increased levels of omega 3 fatty acids including DHA, EPA, DPA in various cuts and parts of poultry meat (legs, breasts etc. with or without skin) that also results in improved production benefits in terms of weight gains, improved flavour, taste, tenderness and less stress in poultry during production/transporting and the production of feeds/food and or ingredients with reduced levels of contaminants e.g. heavy metals.

  • Patent number: 7001610
    Abstract: This invention describes feed supplement, and processes which increase the amount of essential fatty acids in the milk, eggs, meat and other by-products from animals including dairy cattle, beef cattle, goats and poultry. The food supplement described herein includes specific fish meal, fish oil, algae or plant dietary supplements combined with a natural ingredient/coating mixture, which can be either talc, clay or combinations; or mixtures of talc or clay with flax sprout powder to achieve enhanced levels of the essential fatty acids in the milk, eggs, meat and processed livestock products from animals fed this dietary supplement. In ruminants, the natural ingredient/coating mixture prevents microbial degradation of the essential fatty acids in the rumen stomach of the animals fed with this composition, thus providing more of the essential fatty acids to the animal, for their use. This in turn results in improved concentrations in the milk, meat and processed products from these animals.
