A method used in a digital photo frame (DPF) with television (TV) tuning function is provided. The method includes: receiving search parameters input by users during a DPF mode of the DPF; searching in a pre-stored TV program schedule to find TV programs matched the search parameters; determining whether any of the TV programs matched the search parameters is on or about to start at the current time; displaying a program list showing information at least on the “currently on” or “about to start” TV programs among the matched TV programs; switching the DPF from the DPF mode to a TV mode if a “currently on” or “about to start” TV program is selected to play; and receiving and playing the selected TV program. A related DPF is provided.

An audio signal switcher includes a jack switcher and a plug switcher. The jack switcher includes an audio jack and a first USB port. The first USB port includes a first data pin, a second data pin, a power pin, and a ground pin. The audio jack includes a left track segment, a right track segment, and a ground segment, which are isolated coupled to at least three pins of the first USB port. The plug switcher includes an audio plug and a second USB port. The audio plug includes a left track segment and a right track segment which are coupled to a first data pin and a second data pin of the second USB port, respectively. The plug also includes a ground segment divided into a left ground ring and a right ground ring which are connected together to couple to a ground pin of the USB port.

An energy saving system used in an electronic device is provided. The energy saving system includes a battery for supplying the electronic device with energy; a energy detector for measuring a energy level of the battery, and transmitting a battery energy saving control signal when the measured energy level is equal to or less than a predetermined energy level; and a control unit for changing a predetermined first time period into a predetermined second time period which is shorter than the predetermined first time period according to the battery energy saving control signal, and controlling the electronic device to enter a sleep mode state when an elapsed time of not receiving any operations on the electronic device reaches the predetermined second time period.

A touch sensing apparatus is provided. The apparatus includes: a flip-flop, a sensor, an AC signal and a detector. The AC signal supplies AC signals to the flip-flop. The flip-flop outputs a first type output signal at the output thereof when the sensor is not touched. The sensor receives electricity signals from an object, and causes a delay of the AC signal to be inputted to the first input of the flip-flop, the delay of the AC signal to be inputted to the first input of the flip-flop further causes the flip-flop to output a second type output signal at the output thereof. The detector detects a change from the first type output signal to the second type output signal at the output of the flip-flop and accordingly identifies a touch on the sensor.

A method used in a digital photo frame (DPF) with television function is provided. The DPF has a DPF mode for playing multimedia files stored in a storage and a television (TV) mode for playing TV programs received by a TV receiving module. The method includes: fetching TV program information from a TV program schedule when the DPF is in the DPF mode; detecting whether at least one TV program is airing soon or currently aired at the current time; displaying a TV listing menu prompt containing information on the at least one “airing soon” or “currently aired” TV program; receiving a mode switching signal and changing the operational mode of the DPF to the TV mode; and receiving and playing one of the “airing soon” or “currently aired” TV programs.

An RF-controlled power saving communication system includes an electronic device (30), an antenna (60), a radio frequency (RF) receiver (40) and a power saving apparatus (20) for controlling power supply of the electronic device. The RF receiver receives RF signals via the antenna and transmits the RF signals to the electronic device to process. The RF receiver further transmits the RF signals to the power saving apparatus. The power saving apparatus resumes the power supply of the electronic device in accordance with the RF signals.
