The invention is a novel and economical method for detecting infectious microbes, whether airborne or bound to surfaces. A microbe is any microorganism, especially a virus, or bacteria, or fungal spore of any kind. Every infectious microbe has a specific path or vector to invade the human body and cause disease. This inspection and detection method utilizes a real or simulated human cell enzyme coating to bind the target microbe to the sample gathering filter or swab. This greatly increases the sample gathering sensitivity to the target microbe.

An aircraft, system, and method for sensing and/or releasing chemical agents by an aircraft is disclosed. The aircraft, system, and method may employ a chemical sensor, a wind sensor, an imaging device for capturing environmental features, and/or a processor operably coupled therewith. The processor may be used for collecting data from the chemical sensor, the wind sensor, and the imaging device to identify a navigational waypoint and to provide commands to the chemical sensor or to the aircraft based at least in part on collected data.

An environmental sampling system includes a passage in an aircraft component and a removable collector disposed in the passage. The passage has an inlet at a first region and an outlet at a second region. When the aircraft component is in operation the first region is at a greater pressure than the second region such that air flows through the passage from the inlet to the outlet. The removable collector is configured to retain constituents from the air and to react with the media designed to mimic corrosion effects seen at higher temperatures on engine parts. The constituents can then be characterized and correlated to engine deterioration to predict maintenance activity.

The present invention relates to a dust measuring apparatus and, more particularly, to a miniaturized fine dust measuring apparatus. According to one embodiment of the present invention, a non-sampling fluid is discharged irrespective of a speed change of an external fluid, thereby providing a particle sampling probe and a miniaturized fine dust measurement apparatus that provide uniform-speed sampling. Accordingly, it is possible to eliminate a restriction on a place for fine dust measurement.

An air sample collection apparatus and methods for operating the air sample collection apparatus are provided. The air sample apparatus comprises a plurality of air canisters comprising at least a first canister and a second canister, a multi-position valve comprising an outlet, and an inlet region, which are fluidly connected to a plurality of ports. Each respective port is fluidly connected to a canister of the plurality of air canisters, a pump operable to provide pressurized sample air to the inlet region of the multi-position valve, and a computing device operable to open and close each respective port fluidly coupled to each canister of the plurality of canisters.

An aircraft-mountable inflow and outflow apparatus has an accumulating sleeve, an inflow line and at least one exit opening. The regulating sleeve has an entry opening. The inflow line has a supply-line connection for a respective supply line. The accumulating sleeve forms a first supply-line portion, is designed for insertion into a respective shaft of the respective inflow and outflow apparatus and is dimensioned such that, in a state in which the insert has been inserted into the respective shaft, the entry opening of the accumulating sleeve is located in the vicinity of an opening between a respective head part and the respective shaft of the respective inflow and outflow apparatus. Furthermore, the accumulating sleeve is connected to the supply-line connection for a respective supply line via the entry line, which constitutes a second supply-line portion.

A method for determining emissions in an exhaust plume (11) produced by a combustion engine of a vessel (10) during cruise of the vessel (10), said emissions including the presence or concentration of carbon dioxide (CO.sub.2) and/or sulphur dioxide (SO.sub.2) and/or the count and size of particles. The position and distribution of the exhaust plume (11) is determined or estimated on the basis of the position, bearing and speed of the vessel (10) and further on the basis of meteorological data, such as wind direction and speed. An unmanned aerial vehicle (UAV) (12), i.e. a so-called drone, is controlled to fly through the 10 plume (11) to make measurements of exhaust emissions of the vessel (10).

The present invention relates to an environmental monitoring UAV system comprises a drone provided with an air monitoring platform that is adapted for taking air sample(s) by enforcing air to flow through or into at least one sampling medium, during the flight of said drone.

A fluid sampling process and apparatus for maintaining initial sterile conditions so as to reduce or eliminate contaminants in a collected sample and for preventing sample loss.
