A particle detecting module is provided and includes a base, a piezoelectric actuator, a driving circuit board, a laser component, a particulate sensor and an outer cover. A gas-guiding-component loading region and a laser loading region are separated by the base. By the design of the gas flowing path, the driving circuit board covering the bottom surface of the base, and the outer cover covering the surfaces of the base, an inlet path is defined by the gas inlet groove of the base, and an outlet path is defined by a gas outlet groove of the base. Consequently, the thickness of the particle detecting module is drastically reduced.

A nebulizer system capable of identifying when activation has occurred and aerosol is being produced. The nebulizer system monitors the inhalation and exhalation flow generated by the patient and communicates proper breathing technique for optimal drug delivery. The nebulizer system may monitor air supply to the nebulizer to ensure it is within the working range and is producing, or is capable of producing, acceptable particle size and drug output rate. When a patient, caregiver or other user deposits or inserts medication into the nebulizer, the nebulizer system is able to identify the medication and determine the appropriate delivery methods required to properly administer the medication as well as output this information into a treatment log to ensure the patient is taking the proper medications. The system is able to measure the concentration of the medication and volume of the medication placed within the medication receptacle, e.g., bowl.

A method for evaluating a biological material for unassociated virus-size particles having a particular epitope uses a fluorescent antibody stain specific for binding with the epitope and a fluid sample with the virus-size particles and fluorescent antibody stain is subjected to flow cytometry with identification of fluorescent emission detection events indicative of passage through a flow cell of a flow cytometer of unassociated labeled particles of virus size including such a virus-size particle and fluorescent antibody stain.

In accordance with an example embodiment, a method for directing a work machine to one or more worksites from a selection of candidate worksites is disclosed. The method includes receiving obscurant data related to a forecast availability of obscurants at one or more worksites; receiving environmental data related to the suppression, creation, transportation, or direction of obscurants; and receiving operational data related to machine components and the ability of the machine components to generate obscurants or have performance degraded by obscurants at the one or more worksites. Determining an obscurant metric for each of the one or more worksites based on the obscurant data, the environmental data, and the operational data; and directing the work machine to the one or more worksites based on the obscurant metric.

A cell detector and a cell detection method detect cell proliferation. A cell detector includes a light emitter, a culture vessel that accommodates a culture medium containing a cell, a first slit member including a first slit and a first light shield, and at least one light receiver that receives light emitted from the light emitter and passing through the culture medium and the first slit in the first slit member in an order of the culture medium and the first slit. The first light shield in the first slit member blocks light emitted from the light emitter and scattered by the cell in the culture vessel when the cell is at a position overlapping the first slit.
