A health condition estimation apparatus 10 includes an obtaining unit 40 and a controller 42. The obtaining unit 40 obtains gas information. The gas information is based on a signal output by a sensor unit in a period in which a first gas is supplied to the sensor unit and a signal output by the sensor unit in a period in which a second gas is supplied to the sensor unit. The sensor unit outputs a signal with a signal value in accordance with the concentration of a specific gas. The first gas and the second gas are different in at least either of obtaining position and obtaining time. A controller 39 generates health information based on the gas information.

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.

A system for prompt virus infection carriers detection/screening using THz spectroscopy, which comprises a micro/nano-antennas array implemented as an antenna chip of predetermined shape and size, that has the maximum aspect ratio of the capacitor gap being sensitive to both P and S polarization, the array consisting of a plurality of printed micro-antenna elements, each of which having an equivalent inductor L of printed inductors and an equivalent capacitor C defined by gaps between printed contacts the length of the capacitor and the dielectric constant of a filler being between the printed contacts, to thereby determine a resonant frequency of the antenna element, the gaps are formed essentially along the cross diagonals of the each antenna element, thereby obtaining maximal aspect-ratio between the length of the capacitor and the gap width, that maximizes and sharpen the resonance effect of the each micro-antenna element; at least one capsule for holding the chip with the antennas array in a fixed position, preferably at the center, the at least one capsule being at least partially transparent to THz radiation range; means for applying material containing samples of viruses/exhaled biological ingredients to be detected that are exhaled into the gaps, for altering the dielectric constant of the filler and the resonance frequency; a THz spectrometer for scanning the samples and detecting shifts in the resonance frequency induced by the presence of the exhaled viruses/biological ingredients; at least one processor for processing the detected shifts in the resonance frequency and associating different shifts with different types of viruses/biological ingredients. The size of the array is matched to the beam size of the spectrometer, such that the entire radiation collimated beam will be captured by the antennas array, thereby maximizing the signal to noise ratio and the dynamic range.

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.

An apparatus for detecting an alcohol component of a driver's breath includes an inlet that absorbs a driver's exhalation and a passenger's exhalation, respectively, a sensor that detects an alcohol component in the driver's exhalation or the passenger's exhalation, a driver valve controlled to be opened or closed to allow the driver's exhalation to be introduced into the sensor and a passenger valve controlled to be opened or closed to allow the passenger's exhalation to be introduced into the sensor, and a controller that determines whether a passenger is on board a vehicle and controls the driver valve and the passenger valve to be open or closed based on a determination result. Therefore, the driver's breath is distinguished from the passenger's breath and the influence of the passenger is removed to detect the alcohol component in the driver's breath, thereby accurately determining the driver's drinking state.
