Abstract: A sensor system (100) or a sensing method minimizes the loss of aroma chemicals or other analytes in a sample gas while controlling the temperature and humidity of the sample gas. The system (100) may employ a humidifier (120) that adds water vapor to sample gas to provide a known water content, e.g., a saturated humidity at a known temperature. A sensing unit (130) may accurately measure the composition of the sample gas having a known water content, e.g., at a higher known temperature.

Abstract: An optical detector (100, 200, 300) for detecting gas and suspended matter therein includes a test chamber (111, 113), at least one light source (12), a sensing object (131, 133), a test optical sensor (141) and a processor (19). The test chamber (111, 113) accommodates a gas to be analyzed. The at least one light source (12) emits an incident light that enters the test chamber (111, 113). The sensing object (131, 133) is exposed to gas in the test chamber (111, 113), receives the incident light, and reflects or transmits a portion of the incident light to form a test light. The test optical sensor (141) receives the test light and generates a detected spectral signal. The processor (19) receives the detected spectral signal and calculates a detection result according to the detected spectral signal.

Abstract: The present invention provides a tracker and the operation process thereof. In one aspect, the tracker, designed for positioning on a part below a user's knee, provided in the present invention is able to switch between modes such as walking mode, cycling mode, swimming mode, sleeping mode, and other modes by detecting the motions of a user. By the sensing unit included in the tracker, the tracker can further detect signatures, such as steps taken, distance traveled, stairs climbed, calories burned, cycling speed, swimming type, or heart rate, of a user. Furthermore, the tracker in the present invention is able to synchronize or stream information with other devices. In another aspect, the tracker in the present invention is able to control avatars of a game on other devices as a sensory tool.

Abstract: A recognition device of a foot action includes a sensing module, a processing module, and a display module. The sensing module senses the foot action to generate at least one sensing signal corresponding to the foot action, and a form of the sensing signal is a waveform. The processing module is electrically connected the sensing module. The processing module recognizes an action mode corresponding to the foot action according to the waveform and converts the waveform into input data according to the action mode. The display module is electrically connected the processing module and displays the input data. Furthermore, a recognition method of the foot action is also disclosed herein.

Abstract: The present invention provides a stuffed tire for lightweight vehicles, comprising: a wheel; a tire casing, mounted onto the wheel; a harder elastic structure, installed inside the tire casing, and having an end abutted against the wheel; and a softer elastic filler, filled into the tire casing, and having an end abutted against another end of the harder elastic structure, so as to enhance the supporting strength of the tire and the balance of the rotating tire.
