Abstract: An electronic device with touch-link functionality includes a touch panel, a signal processing circuit and a controller. The touch panel includes a first transmitting electrode for transmitting a first signal. The signal processing circuit provides the first signal to the first transmitting electrode. The first signal has a first frequency that is adjustable. The controller is coupled to the touch panel and the signal processing circuit. The controller adjusts the first frequency to make the first frequency correspond to an effective communications range. Within the effective communications range, another electronic device with touch-link functionality is able to receive the first signal, whereas outside the effective communications range, the another electronic device with touch-link functionality is unable to receive the first signal.

Abstract: A mobile device includes a motion detector, a processing unit, and a wireless positioning module. The motion detector is configured to detect a motion of the mobile device to obtain a motion signal. The processing unit is configured to do the followings: process the motion signal to obtain a vibration frequency and a vibration regularity of the mobile device; determine a device activity status of the mobile device according to the vibration frequency and the vibration regularity; and generate a control signal when finding that the device activity status switches from a first activity status to a second activity status. The wireless positioning module is configured to identify a first location of the mobile device in response to the control signal.
