Abstract: An optical detection apparatus and method thereof is provided, which is applicable for detecting the image signals of a labeled sample. First, a laser module provides excitation light, and the excitation light is continuously reflected by a scan module for providing linear scanning light by changing a reflection angle. The carrier moves the light module in a direction nonparallel to the linear direction so as to provide a two-dimensional testing zone. The labeled sample placed in the testing zone is excited by the linear scanning light and generates emission light to be received by the light receiver. Therefore, the light receiver forms the image signals of the labeled sample corresponding to the emission light.

Abstract: A microprocessor-based gas meter has fully electronic control, safety cutoff and data communication functions, while remains the same size of a conventional gas meter. The control circuit board in the microprocessor-based gas meter is mounted inside the main body of the gas meter through a mounting slot. The sensors, wires and battery are located in the rest space of the chamber so as to utilize the space of the chamber. When an abnormal situation is detected, the control circuit activates a cutoff valve and shuts off the gas intake. The data communication function is to transfer gas-metering data through telephone lines to the gas company so that the mistakes and cost of manual checking and recording can be eliminated.
