443 results about "Tick" patented technology

Ticks are arachnids, typically 3 to 5 mm long, part of the order Parasitiformes. Along with mites, they constitute the subclass Acari. Ticks are external parasites, living by feeding on the blood of mammals, birds, and sometimes reptiles and amphibians. Ticks evolved by the Cretaceous period, the most common form of fossilisation being amber immersion. Ticks are widely distributed around the world, especially in warm, humid climates.

Green long-acting zoonosis vector prevention and control medicament

A green long-acting zoonosis vector control medicament provided by the invention is prepared from an insect growth regulator (IGR), a plant essential oil and/or a low-toxicity high-efficiency pesticide, a bactericide, an insect attractant and/or a repellant, a sustained release agent and the like. According to different use conditions and environments, by the adoption of microemulsification and sol technologies, a spraying agent, a sol coating, a film-forming inhibitor and a sol-forming inhibitor are prepared to form different release mechanisms so as to satisfy control demands in different places. The medicament provided by the invention has low toxicity and high efficiency, has effects of killing ovum, inhibiting insect growth and resisting bacteria and mildew, has a long persistent period, is not easy to generate resistance, has low residual, can be used to minimize the spread of diseases and eliminate the pollution caused by unbalance of drug application, is beneficial to the ecological environment, and is used to control zoonosis vectors (such as flea, louse, mite, tick, mosquito, fly, ant, cockroach and the like) in the fields of public place, garden, urban landscaping, means of transportation, neighborhood, hotel, school, restaurant, household, pet, animal husbandry, culturing farm and the like.

Intelligent and conventional transformer substation optical fiber longitudinal difference protection channel joint debugging test method

InactiveCN102721882AGuaranteed correctnessGuaranteed action settingElectrical testingTime informationTransformer
The invention discloses an intelligent and conventional transformer substation optical fiber longitudinal difference protection channel joint debugging test method which is characterized in that the intelligent transformer substation adopts a light inter-range instrumentation group (IRIG)-B code synchronous time tick mode, and the conventional transformer substation adopts a global positioning system (GPS) time tick mode, so that a plurality of points can be subjected to synchronous acquisition and trigger test; during test, relay protection testers on two sides are respectively connected to a GPS clock and an IRIG-B code clock; and time information comprising date, hour, minute, second and the like is sent at the frequency of one time per second. The intelligent and conventional transformer substation optical fiber longitudinal difference protection channel joint debugging test method has the advantages that the intelligent transformer substation adopts the light IRIG-B code synchronous time tick mode, and the conventional transformer substation adopts the GPS time tick mode, so that protection synchronous sampling and synchronous sampling of the testers on two sides are completed by using the two clocks, and a plurality of points can be subjected to synchronous acquisition and trigger test; therefore, the test on dual-end optical fiber current longitudinal difference protection is realized; and the test method is simple, and the data is accurate.
