Abstract: In a component mounting system having an inspection device performing a mounting inspection after component mounting, a correction value for correcting a mounting program is calculated based on board inspection information including fed-back component position deviation information, a component is mounted on a board in accordance with the mounting program corrected based on the calculated correction value, and a “present value” based on most recent board inspection information and a “pre-correction evaluation value” are displayed together on an evaluation value display screen as evaluation values representing accuracy at a time of the mounting based on the board inspection information during this component mounting work, the “pre-correction evaluation value” being calculated based on a temporary position deviation amount pertaining to a case where it is assumed that no correction based on the calculated correction value has been performed.

Abstract: To measure a film thickness of a coating film (25a) of a flux (25) serving as a bonding paste formed on a transfer stage (24) of a paste transfer unit (7), the film thickness of the coating film (25a) in a transfer area (26) is measured through a light-transmitting member (51) by a light interference method and by an optical type film thickness measuring sensor (53) which is arranged below the transfer stage (24). Thus, it is possible to automatically and accurately measure the film thickness of the flux (25) in the transfer area (26) without requiring any complicated measurement work.

Abstract: Determining the lung compliance and lung resistance of a subject undergoing respiratory therapy using non-invasive ventilation requires taking the presence of leaks into account. In particular, variable and unintentional leaks at or near a subject interface appliance may be dynamically determined based on an average resistance of the leak orifice of the subject.
