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: A control system, a mouse and a control method thereof are provided. The control system comprises a dongle and the mouse. The dongle is wiredly connected to a host and has a first light source for emitting a first light. The mouse is wirelessly connected to the dongle and has a transmitter, a second light source for emitting a second light, an optical sensor and a processor. The optical sensor senses the first light at a first time interval to generate a first sensing signal and then also, senses the second light at a second time interval to generate a second sensing signal. The processor generates a first control signal and a second control signal according to the first sensing signal and the second sensing signal, respectively, and transmits them to the dongle via the transmitter so that the host receives the first and second control signals via the dongle.

Abstract: The present disclosure illustrates an optical navigation chip. The optical navigation chip is disposed on an optical navigation module. The optical navigation module includes a light-emitting unit. The light-emitting unit provides a light beam to irradiate a surface of a displacement generating unit. The light beam has a low divergence angle to reduce scattering. The optical navigation chip includes a sensing array and a displacement calculating unit. The sensing array is disposed corresponding to the surface. The sensing array receives a reflected light beam which the surface reflects, and captures an image once every capturing interval based upon the reflected light beam. The displacement calculating unit calculates a relative displacement between the optical navigation chip and the surface according to the images.

Abstract: An image sensing circuit includes floating node, switch circuit, capacitor(s), and counting circuit. The floating node receives image electric charge from a photosensitive pixel. The switch circuit is coupled between floating node and capacitor(s) to dynamically connect and disconnect floating node and capacitor(s). The capacitor(s) include(s) first terminal(s) connected to switch circuit and second terminal(s) connected to ground. The counting circuit counts the number of charging and discharging behavior of capacitor(s) according to dynamic switches of switch circuit wherein the switch circuit dynamically switches to make capacitor(s) be charged and discharged dynamically in response to one exposure time period to receive energy of image electric charge which is determined by the number of charging and discharging behavior of the capacitor(s) and the capacitor(s)' potential value measured finally.
