Environmental Sampling With an Unmanned Aerial Vehicle<\/em>. The patent claims a ducted fan for a vehicle take-off and landing (VTOL) vehicle that includes an annular duct surrounding the fan into which a working fluid is drawn to generate thrust that propels the VTOL and a fluid sample device with a sensor that detects a quality characteristic of a fluid that contacts the sensor. This system could be used to detect environmental hazards in water and other fluid sources without requiring a human operator to travel to the hazard area.<\/p>\n","protected":false},"excerpt":{"rendered":"Unmanned aerial vehicles, or UAVs, have evolved rapidly in recent years, especially since making the leap from military technology to consumer gadgetry. Recently, it\u2019s been suggested that this technology could be useful for a myriad of business opportunities, from food delivery to real estate photography to filming movies. However, the technology has been evolving more quickly than current federal airspace guidelines on the subject, which has proved to be an obstacle blocking the development of drones for commercial and other purposes. Today, we take a look at current drone technologies.<\/p>\n","protected":false},"author":11764,"featured_media":53584,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"content-type":"","footnotes":"","_links_to":"","_links_to_target":""},"categories":[228,3,187],"tags":[7078,33,34],"yst_prominent_words":[27273,27270,27276,27263,27277,27272,27268,27279,27274,27278,27267,27271,27262,27275,27266,27280,27264,27265,27261,27269],"acf":[],"_links":{"self":[{"href":"https:\/\/ipwatchdog.com\/wp-json\/wp\/v2\/posts\/53576"}],"collection":[{"href":"https:\/\/ipwatchdog.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ipwatchdog.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ipwatchdog.com\/wp-json\/wp\/v2\/users\/11764"}],"replies":[{"embeddable":true,"href":"https:\/\/ipwatchdog.com\/wp-json\/wp\/v2\/comments?post=53576"}],"version-history":[{"count":0,"href":"https:\/\/ipwatchdog.com\/wp-json\/wp\/v2\/posts\/53576\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ipwatchdog.com\/wp-json\/wp\/v2\/media\/53584"}],"wp:attachment":[{"href":"https:\/\/ipwatchdog.com\/wp-json\/wp\/v2\/media?parent=53576"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ipwatchdog.com\/wp-json\/wp\/v2\/categories?post=53576"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ipwatchdog.com\/wp-json\/wp\/v2\/tags?post=53576"},{"taxonomy":"yst_prominent_words","embeddable":true,"href":"https:\/\/ipwatchdog.com\/wp-json\/wp\/v2\/yst_prominent_words?post=53576"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
