A hand-held electronic device hand-held electronic device. A sensing surface is adopted to detect fingerprints and a contact of an object on the sensing surface. Storage stores a fingerprint signature. A controller is configured to determine whether a composition of detected fingerprints matches with the fingerprint signature and determine at least one character of the contact. The at least one character comprises a location on which the object contacts the sensing surface.

Methods for controlling a hand-held electronic device and hand-held electronic device utilizing the same

A data transmission method for a data transmission system including a first device and a second device is disclosed. The method comprises the steps of transmitting a clock signal to synchronize the first device and the second device; transmitting a mode signal from the first device to the second device, wherein the mode signal indicates a transmission mode between the first device and the second device; and transmitting a serial data between the first device and the second device based on the clock signal, wherein the length of the serial data is determined based on the transmission mode.

Data transmission method and system

A portable electronic device includes a connector including first and second data pins and a power pin; a battery charging circuit configured to receive a charging current and a power voltage from an external device via the power pin and charge a battery according to the charging current; and a processor configured to make the first and second data pins, which are shorted by the external device, open and obtain an identification code via the first and second data pins from the external device after the first and second data pins are opened, wherein if the identification code matches a specific code, the processor sends a requirement to the external device, and the power voltage and the charging current received by the battery charging circuit are increased by the external device in response to the requirement.

Portable electronic device and charging method therefor

A mobile electronic system including a mobile electronic device and a charging accessory is provided. The mobile electronic device includes a first connector and a battery. The charging accessory includes a second connector. The first connector and the second connector are configured to couple the mobile electronic device and the charging accessory. When the charging accessory is coupled to an alternating-current voltage and the mobile electronic device, the charging accessory converts the alternating-current voltage into a direct-current voltage, detects an instantaneous voltage of the battery, determines the value of the direct-current voltage according to the instantaneous voltage, and outputs the direct-current voltage to charge the battery.

Mobile electronic system and charging accessory

An electronic system includes a first wireless transceiving module having a device identification code and a portable device. The portable device may include a second wireless transceiving module, and a processor. The second wireless transceiving module obtains the device identification code from the first wireless transceiving module. When the second wireless transceiving module obtains the device identification code from the first wireless transceiving module, the processor checks whether the device identification code matches to a pre-built identification code; and when the device identification code matches to the pre-built identification code, the portable device automatically determines a position of the portable device, and displays a map related to the position of the portable device in a display.

Electronic system and controlling method thereof

A touch-controlled electronic device with a wireless communication function and a method for reducing wireless signal interference to a touch sensing function are disclosed. The electronic device includes a wireless communication module, a touch sensing module and a synchronous signal interface. By the synchronous signal interface, a synchronous signal is transmitted between the wireless communication module and the touch sensing module and, accordingly, the transmission of the wireless signal is staggered from the timing that receiver electrodes of the touch sensing module receive sensed signals. Thus, wireless signal interference to the touch sensing function of the touch sensing module is suppressed.
