An information processing method includes obtaining image information including a first image of a first person in a predetermined facility and a second image of a second person in the predetermined facility; classifying each of the first person and the second person as a resident of the facility or a visitor to the facility, the first person being classified as the resident, the second person being classified as the visitor; calculating a distance between the first person and the second person, based on the first image and the second image; determining whether the first person and the second person are having a conversation with each other, based on the calculated distance; measuring, when it is determined that the first person and the second person are having a conversation with each other, a conversation time during which the first person and the second person are having a conversation with each other; and transmitting, when the measured conversation time exceeds a predetermined time, infection notification information indicating that a risk of the first person contracting infectious disease is high to a terminal apparatus.

Information processing method, recording medium, and information processing system

Provided is an information processing method executed by a computer. The information processing method includes detecting a cough or a sneeze of a person who is in a predetermined space; acquiring an image of the predetermined space captured when the cough or the sneeze is detected; recognizing a state around a mouth of the person from the image; generating, based on the recognized state around the mouth of the person, a control signal for controlling at least one of a direction or a volume of air that is to be sent from an airflow generation apparatus that generates an airflow in the predetermined space; and outputting the generated control signal.

An infection risk map provision system includes virus sensors for detecting viruses in the air, the virus sensors being provided at different positions, a communication unit that collects detection information obtained by the virus sensors, and a control unit that provides, on the basis of the detection information, an infection risk map representing the distribution of infection risk information. The control unit sets display granularity for the infection risk information on the infection risk map displayed on an information terminal on the basis of granularity information corresponding to the virus sensors and creates the infection risk map by superimposing the infection risk information upon a map on the basis of the set display granularity and positional information.

A cleaning route determination apparatus includes a calculation condition inputter that receives a calculation condition including information regarding an inside of a facility, an analyzer that analyzes, on a basis of the calculation condition, behavior of airflow and particles inside the facility, a map generator that generates, on a basis of a result of the analysis, a dust accumulation map indicating dust accumulation areas inside the facility and one or more dust amounts corresponding to the dust accumulation areas, a classifier that selects, on the basis of a certain condition, clusters from among clusters inside the facility, and a route calculator that determines a first route from second routes. Each of the second routes is a route for a cleaner to pass through, within a certain period of time, at least one dust accumulation area included in the clusters selected from among the clusters.

A cleaning route determination system includes an analyzer that analyzes behavior of airflow and particles inside a facility, a map generator that generates a dust accumulation map indicating one or more dust accumulation areas inside the facility and one or more dust amounts corresponding to the one or more dust accumulation areas, and a route calculator that determines a first route from second routes. Each of the second routes is a route for a cleaner to pass through, within a certain period of time, at least one of the one or more dust accumulation areas. A total amount indicating a sum of dust amounts corresponding to dust accumulation areas included the first route is largest among total amounts corresponding to the second routes, each of the total amounts indicating a sum of dust amounts corresponding to dust accumulation areas included in each of the second routes.

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.

Self-propelled pathogen detection device, pathogen detection system, and control method

A liquid treatment device comprises: a first insulator including a first opening and a first inner surface, a gas being emitted into a subject liquid through the first opening; a first electrode that is at least partially disposed within a first space surrounded by the first inner surface; a second electrode that is at least partially disposed within the subject liquid; a gas supply source; and a power supply source. The first inner surface includes a first partial region which contacts the first opening. A forward end of the first electrode protrudes from the first opening to outside the first space, or the forward end retreats from the first opening into the first space by less than 3 mm. A first distance, which is a shortest distance between an outer surface of the first electrode and the first partial region, is 1 mm or greater.

Liquid treatment device utilizing plasma

A liquid treatment apparatus includes a liquid storing vessel, a first electrode, a second electrode at least partly arranged inside the vessel, a tubular first insulator surrounding a first-electrode lateral surface with a first space interposed therebetween, and including a first opening in an end surface in contact with the liquid, a tubular second insulator surrounding the first-electrode lateral surface inside the first insulator, a gas supply device supplying gas into the first space and ejecting the gas into the liquid through the first opening, and a power supply applying a voltage between the first and second electrodes and producing plasma. The second insulator is arranged with a second space interposed between the first and second insulators. Portions of the first and second insulators, those portions being positioned inside the vessel, are covered with the gas when the gas is supplied into the first space by the gas supply device.
