Abstract: There is provided a capacitive communication system including an object and a capacitive touch panel. The object includes a plurality of induction conductors configured to have different potential distributions at different time intervals by modulating respective potentials thereof. The capacitive touch panel includes a plurality of sensing electrodes configured to form a coupling electric field with the induction conductors to detect the different potential distributions at the different time intervals. When the different potential distributions match a predetermined agreement between the object and the capacitive touch panel, a near field communication is formed between the object and the capacitive touch panel.

Abstract: There is provided a displacement detection device including a light source, an image sensor and a processing unit. The light source provides light to a finger with a light source parameter. The image sensor receives reflected light from the finger, outputs valid images when the light source is being turned on and outputs dark images when the light source is being turned off. The processing unit determines a contact status according to one of the dark images and one of the valid images, and calculates a displacement according to two of the valid images to accordingly adjust the light source parameter.

Abstract: There is provided a mobile carrier and an auto following system using the mobile carrier. The mobile carrier is capable of capturing at least an image of a guiding light source and automatically following the guiding light source based on the captured image of the guiding light source. The mobile carrier is further disposed with a mobile light source for a remote image sensing device to capture an image of the mobile light source while the mobile carrier cannot capture the image of the guiding light source, so that the mobile carrier can be guided by a control signal provided according to the captured image of the mobile light source.
