Abstract: A cleaning system and a cleaning method are provided. The cleaning system includes a main body, an air suctioning device, a light source, an optical sensor, a memory and a processing unit. The air suctioning device includes an air flow passage and a fan-motor assembly that is disposed in the air flow passage and generates a suction force to suction outside air through the air flow passage. The light source emit light to the air flow passage. The optical sensor captures a plurality of successive image frames from the air flow passage. The processing unit is configured to: obtain first and second image frames from the successive image frames; compare the first image frame with the second image frame to identify dust particles; obtain a particle feature of the dust particles; and determine a current cleanness condition according to the particle feature.

Abstract: A navigation device applied to a wireless identification tag includes a movable signal transceiver and an operation processor. The movable signal transceiver is adapted to transmit a detection signal and receive an actuation signal relevant to the detection signal. The operation processor is electrically connected to the movable signal transceiver. The operation processor is adapted to analyze the actuation signal to acquire relative position between the movable signal transceiver and the wireless identification tag, and generate a motion parameter in accordance with the relative position for moving the movable signal transceiver.
