A data transmission system includes a sender, at least one receiver, a sender controller, and a receiver controller. The sender controller receives an AC signal from an AC power source via a first AC input port, receives data from the sender via a first data port, and processes the received AC signal according to the received data, and outputs a processed AC signal via a first AC output port. The receiver controller receives the processed AC signal from the sender controller via the second AC input port, powers the at least one receiver using the processed AC signal via the second AC output port, and converts the processed AC signal to corresponding data and transmits the data to the at least one receiver via a second data port.

Data transmission system based on a power line

A method for controlling a normally closed relay includes: providing power to at least one of a first electromagnet and a second electromagnet via a power input port, then cause a first actuation member and a second actuation member to separate from each other, and the relay is then in an open state; and stopping providing power to the at lease one first electromagnet and the second electromagnet which being powered by the power input port such that the first actuation member and the second actuation member makes contact with each other, and the relay is then in a closed state.

The present invention provides a mobile phone for authenticating Subscriber Identification Module (SIM) card and a SIM card authentication method adapted for the mobile phone. Once a SIM card is inserted into the mobile phone, the mobile phone acquires a phone number associated with the inserted SIM card and identifies whether the acquired phone number has been stored in the non-erasable programmable memory of the mobile phone. If yes, the user is legal and can use the mobile phone, if no, then the user is illegal and cannot use the mobile phone. Therefore, the mobile phone protects and hides stored information from the user.

Mobile phone for authenticating SIM card and method thereof

A master-slave system includes a master and a slave. The master includes a first communication interface, a master controller, and a voltage meter. The voltage meter is connected to the first communication interface and the master controller. The slave includes a second communication interface, an input unit, a slave controller, and a control indicator unit. The control indicator unit is connected to the second communication interface and the slave controller. The salve controller controls voltage of a node between the control indicator unit and the second communication interface to change between a high logic level and a low logic level according to signals from the input unit. The voltage meter is connected to the control indicator unit to detect the voltage of the node. The master controller controls the master to execute a function according to change of the obtained voltage within a preset period.

Master-slave system with reversible control direction function

A method for measuring size of an object is provided. The method includes controlling a distance measurement unit to measure a vertical distance between an electronic device and the object in response to a measurement operation, controlling an image capturing unit to capture an image in front of the electronic device, which includes an image of the object in response to the measurement operation. Computing an actual size of the captured area according to the distance measured by the distance measurement unit and an angle of view of the image capturing unit. In addition, obtaining the image of the object from the captured image, and further computing the proportion of the image of the object in the captured image. Then computing the size of the object according to the proportion and the actual size of the captured area, and displaying the measured size of the object.

Electronic device with measurement function and measurement method thereof

An electronic device with time update function includes a radio module, a clock module, an audio input port, a storage module, and a processing module. The radio module receives and outputs audible signals from the broadcasts of a broadcasting station. The audio input port receives audible sound generated by the radio module, and the clock module provides a source of real time. The processing module determines whether the signals received by the audio input port include current time information, and if so whether the system time is consistent with the current time information. The processing module updates the stored initial time with the current time information and adjusts the system time as necessary. A time update method is also provided.

Electronic device with time update function and time update method

A data converter includes a signal input port, a processing unit, and an output port. The signal input port includes a number of ports for connecting to corresponding ports of an electronic device and receiving waveform signals from the electronic device. The processing unit includes a port detection module for detecting which port of the signal input port is receiving the waveform signals and a data conversion module including a number of conversion sub-modules, each conversion sub-module corresponds to one port of the signal input port. When the port detection module detects the port receiving the waveform signals, the conversion sub-module corresponding to the detected port is enabled and converts the waveform signals to digital data. Then the output port outputs the digital data to a computer, and the communication state of the port of the electronic device is analyzed via the computer based on the digital data.

Data converter for converting waveform signal to digital data

The present invention provides a telecommunication system, a mobile phone and a calling method adapted for the telecommunication system. The telecommunication system includes a mobile phone connected to a wireless network and a wired phone connected to a wired network. The mobile phone and the wired phone communicate each other within a predetermined coverage area. When there is not a wired phone within the predetermined coverage area or there is a wired phone within the predetermined coverage area and the current state of the wired phone is busy, the mobile phone makes a call via the wireless network. If there is a wired phone within the predetermined coverage area and the current state of the wired phone is idle, the mobile phone sends a phone number to the wired phone, and the wired phone makes the call via the wired network.
