Abstract:
A method and electronic device for transmitting an emergency signal. The method includes: establishing a short-range communication link with a counterpart electronic device using a first short-range communication network; generating an emergency signal when the short-range communication link with the counterpart electronic device is cut off; and broadcasting the emergency signal using a second short-range communication network.
Abstract:
An analog-to-digital converter includes a comparator, a switch, and a counter circuit. The comparator is configured to generate a comparison signal by comparing an analog signal received through a first signal line and a reference signal received through a second signal line. The switch is coupled between the first signal line and the comparator. The switch is open before the analog signal is applied to the first signal line to disconnect the first signal line from the comparator, and is closed after the analog signal is applied to the first signal line to provide the analog signal to the comparator. The counter circuit is configured to generate a digital signal corresponding to the analog signal by performing a count operation in synchronization with a count clock signal based on the comparison signal.
Abstract:
An ambient light sensor includes a photoelectric conversion unit, a current control unit, a signal conversion unit and a comparison unit. The photoelectric conversion unit provides a photo current having a magnitude corresponding to illuminance of incident light to a first node. The current control unit generates a control current exponentially proportional to an elapse time based on a clock signal, provides the control current to the first node, and outputs a digital code corresponding to the elapse time in response to a reset signal. The signal conversion unit generates a comparison voltage logarithmically proportional to a sum of the photo current and the control current. The comparison unit generates the reset signal by comparing a magnitude of the comparison voltage and a magnitude of a reference voltage. The ambient light sensor generates the digital code effectively representing illuminance of ambient light that eyes of a human being perceives.
Abstract:
A method and an apparatus are provided for executing a plurality of objects displayed on a screen of an electronic device. The plurality of objects are displayed on the screen of the electronic device. Each of the plurality of objects is used to execute an application upon selection of a respective object. Information about a first object, of the plurality of objects, corresponding to a first application and information about a second object, of the plurality of objects, corresponding to a second application, are linked. Link information about the linked first and second objects is stored. The second application is executed upon receipt of a predetermined input value from an input means during execution of the first application.
