The present invention relates to an aerosol sampling system operating at a high temperature and pressure, and in particular to a system which is able to sample and analyze an aerosol. The present invention aims to provide a system which is able to carry out measurements, for example, a sampling, an analysis, etc. at a high temperature and pressure, which was unavailable in the past since there is not any aerosol measuring system to sample and analyze at a high temperature and pressure.

A device (1) for detecting a concentration of predetermined particles, particularly viruses, in air (3) with organic and/or inorganic aerosol particles, has a supply unit (10), an imaging unit (20), an image acquisition unit (40) and an evaluation unit (50). The supply unit (10) binds the aerosol particles as particles in a fluid (4). The imaging unit (20) operates on the functional principle of a scanning electron microscope in order to generate an enlarged image of the particles contained in the fluid (4). The image acquisition unit (40) acquires and transmits the image. The evaluation unit (50) evaluates the particles depicted in the image. The evaluation unit (50) automatically detects morphological properties of the particles depicted in the image and compares the detected morphological properties with morphological properties of the predetermined particles. Through the comparison, it determines a proportion and/or number of predetermined particles in the image and the concentration of the predetermined particles in the air (3).

An apparatus for passive sampling of airborne particles such as those found in an aerosol is disclosed. The passive sampler is designed to take advantage of natural air flow to collect airborne particles, such as those contained in an aerosol, for subsequent analysis. The passive sampler increases the sampling efficiency for diffusion and electrostatic collection of particles by using natural airflow or movement to bring particles closer to the deposition surface. Alternately charged electret filters further increase the sampling efficiency.

A method includes receiving, from an imaging device associated with a robotic apparatus, an image signal including an object of interest represented in the image signal; receiving, by the robotic apparatus from an external agent, a task indication related to the object of interest, the task indication representative of a task to be performed by the robotic apparatus with respect to the object of interest; and responsive to receipt of the task indication: detecting salient features of the object of interest within the image; storing, by the robotic apparatus, a task context, the task context comprising data pertaining to the salient features and data pertaining to the task indication; and commencing, by the robotic apparatus, the task with respect to the object of interest.

A filter for mimicking regional lung deposition is provided that includes filter layers of fibrous filter material stacked coaxially and an outer ring portion encircling the fibrous filter material and securing the filter layers together. The fibrous filter material is formed for fibers having a fiber diameter, and the filter has a tunable filter efficiency. A regional lung deposition system capable of measuring constant flow or variable flow is provided that includes a throat simulation device, a filter housing downstream of and in fluid communication with the throat simulation device, a breath simulator downstream of and in fluid communication with the filter housing, and a an above-referenced filter positioned within the filter housing. Also provided is a filter housing for use in the regional lung deposition system that includes a conical housing having a small inner diameter at a first end and a large inner diameter at a second end.

A kit has a separating device and a particle sensor. The separating device is arranged upstream of the particle sensor and is set up to leave only respirable particles in the fluid stream, so that only those particles which have a particle diameter in a range from 0 to 10 μm reach the particle sensor and are analyzed by it. As a result, the particle sensor can be effectively protected from undesired contamination and its measuring accuracy can be increased considerably by reducing the number of particles to be analyzed that enter its measuring region. In a second aspect, the invention relates to the use of the proposed kit in a dust device. In further aspects, the invention relates to a dust device which includes a proposed kit, as well as a method for controlling a dust device in dependence on the measurement data determined with the kit.

An automated control system including an unmanned aerial vehicle (UAV) and an input device. The UAV includes: a sensor, a receiver; and memory. The memory includes a task association data including one or more tasks for execution by the UAV. The input device includes a tagging block. The tagging block allows an operator to tag an object of interest and send a tag regarding the object of interest to the UAV, via the receiver, wherein the object of interest is located within a visual field of the UAV. The sensor processes data within the visual field and the input device is configured to communicate the object of interest from the visual field tagged by the operator. The task is selected from the task association data and the UAV executes the task with respect to the object of interest from the visual field.
