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: An optical navigation device, comprising: at least one image sensor, configured to sense at least one sensing image; and a processing circuit, configured to determine at least one abnormal region in the sensing image and control the optical navigation device to inform the abnormal region exists to a user.

Abstract: There is provided an electronic device capable of improving the difficulty of breaking a digital electronic lock and the accuracy of gesture control. The electronic device is unlocked according to gestures of a single hand or two hands, an operation hand, a gesture position, a staying time of gesture and a gesture variation of a user. The electronic device further improves the accuracy of gesture control in conjunction with an accessory pattern, temperature sensing and space information of a wearable device. The present disclosure further provides an electronic device that identifies legitimacy of moving the electronic device according to a variation sequence of 3-axis accelerations of an accelerometer.

Abstract: A temperature detecting apparatus is provided. The temperature detecting apparatus includes a movable carrier and a thermal sensor. The movable carrier includes a control module, and is movable in a working place according to a designated command. The thermal sensor is assembled to the movable carrier and is electrically coupled to the control module. When the movable carrier is moved according to the designated command, the thermal sensor is configured to detect the working place so as to generate an immediate temperature distribution of the working place. Moreover, when the immediate temperature distribution generated from the thermal sensor has an abnormal temperature value, the control module is configured to emit a warning signal to an external apparatus.

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.

Abstract: A multiple detection system is applied to a vehicle and includes a contact-type detection module adapted to generate a contact-type detection datum, a contactless-type detection module adapted to generate a contactless-type detection datum, and an operation processor electrically connected with the contact-type detection module and the contactless-type detection module in a wire manner or in a wireless manner. The operation processor sets at least one of the contact-type detection datum and the contactless-type detection datum according to an environmental status of the vehicle to be a main detection result of the multiple detection system, and further sets the other detection datum to be an auxiliary detection result of the multiple detection system, for acquiring a passenger feature inside the vehicle.

Abstract: An electronic device control method, for calling a first electronic device in a building, comprising: (a) receiving a call command from an user by the first electronic device; (b) acquiring map information of the building by the first electronic device corresponding to the call command; and (c) driving the first electronic device to go to a user region in which the user is located according to the map information, wherein the user region is a predetermined region of a user location of the user.
