摘要:
An IR controlling device includes a display panel, a number of IR emitters, a number of IR receivers, and a receiving controller. The IR emitters and the IR receivers are staggered under the display panel, and facing the display panel. The IR emitters are to emit IR beams in sequence, and the IR receivers are to receive the IR beams reflected by an external object. The receiving controller generates a plurality of response signals corresponding to the IR receivers. An IR processing unit receives the response signals, and determines a virtual position of the external object on the display panel. A controlling unit outputs a control signal and executes a corresponding function. A display processing unit receives the control signal and updates the content on the display panel.

An electronic device includes a first rechargeable battery, a solar cell mounted on the electronic device, a second rechargeable battery and a power management circuit. The power management circuit includes a control module, a DC/DC module, a switch and a power supply switching module. The DC/DC module is configured for converting the DC power generated by the solar cell from one voltage level to another, and activating and maintaining the activation of the control module. The switch is turned on by the control module when the control module is activated, causing the DC power from the DC/DC module to charge the second rechargeable battery. The power supply switching module is controlled by the control module to select the second rechargeable battery to power the electronic device if the voltage level of the rechargeable battery is lower than that of the second rechargeable battery.

A touch input method includes steps: controlling one of the infrared emitters to turn on and send an infrared signal to the infrared receivers in sequence, thus forming a number of first infrared lines. Detecting whether an infrared receiver does not receive the infrared signal. Determining if the first infrared line is blocked by an object, thus determining a first blocked infrared line. Controlling the other infrared emitter to turn on and send the infrared signal to the infrared receivers, thus forming a number of second infrared lines. Determining if the second infrared line is blocked by the object, thus determining a second blocked infrared line. Determining touch position according to the first and the second blocked infrared lines, executing the function of a GUI element corresponds to the touch position. The disclosure also provides an electronic device with an infrared touch panel.

An electronic device includes a main control system, a power key, a touch screen, and a touch screen control unit. The touch screen includes a plurality of infrared emitters, a plurality of infrared receivers and an infrared light grid comprising an infrared light beam passing through the power key. The touch screen control unit includes a scan controlling module, a detecting module, and a power controlling module. The scan controlling module periodically scans the infrared light beam passing through the power key. The detecting module determines whether a blocked time of the infrared light beam passing through the power key reaches a first predetermined time period. The power controlling module powers on or off the main control system when a time of blocking the infrared light beam passing through the power key being blocked reaches the first predetermined time period. A related method is also provided.

A computer mouse includes a housing and two wheels that are capable of rolling on a supporting surface. A first pair of light sources and a second pair of light sources are arranged at one side of the two wheels, respectively. A light sensor changes from a first state to a second state after receiving light, and changes from the second state to the first state after the light is blocked. A driving module is used for successively turning on the first pair of light sources and the second pair of light sources in a first frequency. A scanning module is used for scanning the light sensor in a second frequency, to obtain states of the light sensor. A controlling module is used for generating data representative of movement of the housing according to the states of the light sensor.
