Abstract:
A theft warning system includes a first electronic device and a second electronic device. The first electronic device is configured for transmitting monitoring signals, wherein the frequency of the monitoring signals is capable of changing according to change in the voltage supplied to the first electronic device. The second electronic device communicates with the first electronic device by receiving the monitoring signals transmitted by the first electronic device, and generating alarms when a frequency of the received monitoring signals is changed. A theft warning method applied to the electronic device is also provided.
Abstract:
A television includes a television signal receiving unit, a communication signal receiving unit, a processor, and a display unit. The television signal receiving unit is configured to receive TV signals. The communication signal receiving unit is configured to receive communication signals from a communication device. The processor is used for processing the TV signals to generate first video signals, and extracting second video signals from the communication signals. The display unit is used for displaying the first video signals default. When the communication signal receiving unit receives the communication signals, the processor controls the display unit to display the second video signals.
Abstract:
An information gathering apparatus for gathering information from a scannable document including a plurality of information regions includes a plurality of gathering circuits corresponding to the plurality of information regions. Each gathering circuit emits light to the corresponding information region and receives light reflected from the corresponding information to generate electrical signals based on an intensity of reflected light.
Abstract:
A display control method includes: generating an input signal according to a mouse input operation; detecting whether the input signal includes a scroll signal generated when a scroll wheel of the mouse is scrolled, and a press signal generated when a predetermined button of the mouse is pressed; and moving the contents of the document being displayed left or right when a detected result is the input signal including the scroll signal and the press signal.
Abstract:
An exemplary charging control circuit includes a signal shaping unit, a first switch unit, and a second switch unit. The signal shaping unit receives a control signal, and is capable of reshaping the received control signal to have a time interval transited from a first state to a second state. The first switch unit receives the shaped control signal, and generates a first switching signal. The second switch unit receives the first switching signal, and is capable of being turned on based on the first switching signal for allowing electrical power to be outputted to a battery.
Abstract:
