The present disclosure provides a self-propelled pathogen detection device in which a place where a pathogen is highly likely to be present in a space such as an inside of a facility is allowed to be configured preferentially to be a target region of detection. The self-propelled pathogen detection device according to the present disclosure comprises a housing; a detection part for detecting a pathogen; a movement mechanism for moving the housing; a position acquirement part for acquiring position information representing a current position of the housing in a space; and a control part which determines a target region in the space on the basis of traffic line information on a person in the space, and controls the movement mechanism to move the housing in the target region on the basis of the position information. The detection part detects the pathogen in the target region.

A method and a device for measuring an oxygen content of a headspace gas in a beverage can. The beverage can is oriented upside down to allow the headspace gas to collect at the bottom. A hollow piercer on a piercing head forms a sampling opening in the bottom of the can through which the sampling tube penetrates. The liquid level in the beverage can is lowered to establish a direct connection of the gas-filled headspace and the sampling opening. Then the headspace gas is transported from the headspace to a sensor unit via the sampling tube and/or the hollow piercer or the piercing head. The oxygen content and/or an oxygen partial pressure and/or a headspace volume of the headspace gas are determined by the sensor unit. The sampling opening is closed off airtight by sealing elements arranged on the piercer or the piercing head.

A method for collecting aerosol particles in exhaled breath of a user using a portable handheld sampling device by means of a reopening breathing maneuver.

The present invention includes an apparatus and method for detecting the location of one or more sources of one or more target molecule, the apparatus comprising: a molecule detector; and a processor connected to the molecule detector and to a global position system, wherein the processor calculates the presence of the one or more target molecules, runs a computer code that determines a dynamic reverse gas stack model for the one or more target molecules, and triangulates the possible position for a source or effluent of the one or more target molecules based on the dynamic reverse gas stack model. The determined reverse gas stack model may have a Gaussian dispersion over one or more sampled locations.

A bioaerosol detector is operated in accordance with one or more first inputs. Operating the bioaerosol detector includes filtering pathogens from the air, extracting genetic material from the filtered pathogens, and analyzing the extracted genetic material to identify the filtered pathogens. While operating the bioaerosol detector in accordance with the one or more first inputs, a change is identified in an operating condition for the bioaerosol detector. In response, the bioaerosol detector is operated in accordance with one or more second inputs. At least one input of the one or more second inputs is distinct from a respective input of the one or more first inputs.

In order to achieve improved determination of fine dust particles, a method is provided for determining particles of an aerosol whereby, in a first measuring step, aerosol is fed to an optical aerosol measuring device without being influenced by a controllable centrifugal separator, at least in a further measuring step aerosol is guided to the optical measuring device while being influenced by the centrifugal separator rotating at least at a speed deviating from the speed 0, and properties of the particles of the aerosol are determined from the received measurement signals of the optical measuring device in the first and in at least one further measuring step. A device is also provided, which has an optical sensor unit forming the measuring volume for recording particles, and is designed such that a separator for size- and/or mass-sensitive separation of particles is arranged upstream of the sensor unit.

The present invention refers to a device comprising polytetrafluorethylene (PTFE) filters and the use of the same for collecting, detecting and identifying organisms present in air ecosystems. The invention also provides a method suitable for the capture, detection and identification of whole airborne biological particles, including viruses and other important air pathogens, which involves the use of the device. This method allows toperform organism, preferably viral, metagenomics to sequence all DNA and RNA organisms captured in the filters. This methodology may be used to detect, for instance, SARS-CoV2 particles in air samples.
