Abstract: An auscultatory sound analysis system that makes it possible to chronologically understand qualitative changes in an auscultatory sound from an auscultation device that contributes to telemedicine avoiding medical practice involving users' close contact, in medical care having a possibility of a contact infection such as COVID-19. The auscultatory sound analysis system converts the auscultatory sound into digital data, further performing a spectrogram conversion, and chronologically outputting, along a time axis, strengths of a signal component at a specific frequency or in a specific frequency range. The system thereby makes it possible to output, to transfer data of, and to display quantitative and temporal changes in high-pitch crepitations caused by interstitial pneumonia from COVID-19 and to thus understand a development status of the disease.

Abstract: The lighting system according to the present invention includes an electrical wiring substrate in which a connector to a power source is formed, a plurality of LED chips mounted in a predetermined array pattern on the electrical wiring substrate, a deflection lens array disposed in proximity to the LED chips between the LED chip and the predetermined illumination region and a housing for receiving the electrical wiring substrate and the deflection lens array. A plurality of deflection lenses are integrally molded in the deflection lens array to lead lights from the LED chips to the predetermined illumination region in a state where the lights from the LED chips are superposed with each other. The lights emitted from the LED chips are collected in a state where they all are superposed in a common, single illumination region through the deflection lenses.
