Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: A gas detection system for gynecological disease detection and a detection method using the same are provided. The gas detection system is configured to detect an analyte from a female vagina and includes: a main body, a sleeve, a detection module, a pump, and a control module. The main body includes a body portion and a head portion having an intake channel. The body portion includes a detection chamber and an exhaust channel. The detection module includes at least one sensor configured to detect at least one target of the analyte and produce at least one detection signal. The pump is communicated with the detection chamber and the exhaust channel. The control module includes a processing unit and a first communication unit. The processing unit receives the at least one detection signal and controls the first communication unit to send the at least one detection signal.

Abstract: The present invention provides a pneumonia detection device for detecting an exhaled air of a patient to determine whether the lungs of the patient have been infected by at least one bacterial species. The device comprises a multi-gas sensing module, a temperature and humidity control module, and an operation control unit. The multi-gas sensing module comprises a gas sensor array reacting with a gas metabolized from the bacteria to generate a plurality of characteristic signals. The temperature and humidity control module controls and measures an operational condition of 45° C.-60° C. and humidity between 7% and 20% for the gas sensor array. The gas sensor array contacts with the exhaled air to generate a plurality of measurement signals. The operation control unit comparisons the measurement signals and the characteristic signals of different bacteria to generate a result determining whether the patient has contracted the bacteria.
