Abstract: A suction cleaner and an operation method thereof are provided. The suction cleaner includes a housing, a holding part, an impeller module, at least one sensing device, and a controller. An end of the housing has a dust-suction opening. The impeller module is located inside the housing, and a channel is located between the impeller module and the dust-suction opening. The controller is electrically connected to the sensing device to drive and adjust the rotation rate and the suction force of the impeller module, and thus the power consumption of the suction cleaner can be reduced.

Abstract: A defect detection system and method enable a fastened crystalline silicon product to generate micro-vibration by a micro-vibration excitation device, so as to enable the crystalline silicon product to generate an excitation signal, then to acquire the excitation signal by a acquisition device, so as to analyze the excitation signal acquired by the acquisition device in the time and frequency domain by an analysis detection device with a specific analysis, and to obtain an analysis result, at last, determine a defect state of the crystalline silicon product according to the analysis result.

Abstract: A method for navigation of a movable platform is provided. The method includes the steps. First, a plurality of reflection devices is placed to mark a range. A coordinate location and a direction of the movable platform are received by a positioning system, At least one laser to measure relative positions and distances between the reflection devices and the movable platform are emitted by a laser range finder, respectively. Absolute locations of the reflection devices and the range are calculated by a processor according to the coordinate location and the direction of the movable platform, the relative positions and the distances between the reflection devices and the movable platform. The reflection devices are scanned and tracked by the processor, and the coordinate location and the direction of the movable platform and the absolute locations are calibrated by the processor to control the movable platform to move in the range.
