Abstract:
An exemplary method for testing light-emitting diodes (LEDs) on a motherboard is provided. The method includes: using a camera module to take a first bulb image of a corresponding number of transparent bulbs which are connected to each of the LEDs when the LEDs are set in a power-on state and taking a second bulb image of the transparent bulbs when the LEDs are set in a power-off state; processing the two bulb images and dividing each of the two bulb images into small pictures; calculating an average pixel value of each of the small pictures, calculating a first difference of each of the small pictures between the average pixel value and a first predetermined value, and calculating a second difference of each of the small pictures between the average pixel value and a second predetermined value; ascertaining a present state of each of the LEDs by comparing the two differences; obtaining test results by comparing the present state of the LEDs with the set state; and reporting the test results. A related system is also provided.

Abstract:
A system for testing audio of a motherboard includes a recording fixture and a computer. The recording fixture includes a recording device and a soundproof device. The soundproof device is configured for soundproofing the audio device and the recording device from environmental noise. The computer includes an output/input module, a comparing module and a displaying module. The output/input module is configured for outputting a first sound signal generated by the computer to the audio device to cause the audio device to generate a sound and receiving the sound generated by the audio device and recorded by the recording device from the recording device and transforming the sound into a second sound signal. The comparing module is configured for comparing the first and second sound signals. The displaying module is configured for displaying the compared result.
Abstract:
A handheld device includes a display, a touch panel opposite to the touch panel, and a controller. When a point on the touch panel is touched, the touch panel outputs a first signal corresponding to the location of the point being touched. The controller receives the first signal, and outputs a second signal according to the first signal to control a cursor displayed on the display screen. The location of the cursor is corresponding to the location of the point on the touch panel.
Abstract:
An exemplary method and system for testing light-emitting diodes (LEDs) uses a camera module to take two bulb images of transparent bulbs connected to each of the LEDs. A first bulb image is captured when the LEDs are set in a power-on state, and a second bulb image is captured when the LEDs are set in a power-off state. The method divides each of the two bulb images into small pictures, and calculates an average pixel value of each of the small pictures. After calculating a first difference of each of the small pictures between the average pixel value and a first predetermined value, and a second difference of each of the small pictures between the average pixel value and a second predetermined value, the method ascertains a present state of each of the LEDs by comparing the two differences.
Abstract:
An audio signal processing device receives a first voice analog signal from a portable electronic device and a second voice analog signal of noise from outside environment, and converts the first voice analog signal and the second voice analog signal into a first voice digital signal and a second voice digital signal, respectively. The first voice digital signal and the second voice digital signal are then mixed up to obtain a third voice digital signal. The third voice digital signal is converted into a third voice analog signal outputted to an earphone. A regulator is used to adjust signal intensity of the first voice analog signal and the second voice analog signal.
Abstract:
A hands-free mobile phone includes a housing and a hands-free unit. The housing defines two outer slide channels and two inner slide channels inside the corresponding outer slide channels. Each outer slide channel includes an access hole, a pivot hole, and a coupling passage communicating the access hole with the pivot hole. Two pivot portions are formed on the hands-free unit. Each pivot portion includes a pivot shaft and a plugging end formed on the pivot shaft. The plugging ends of the pivot portions are respectively inserted in the inner slide channels through the access holes of the corresponding outer slide channels and the pivot shafts thereof are respectively placed in the corresponding access holes and slid into the pivot holes of the outer slide channels through the corresponding coupling passages. Thus, the hands-free unit is pivotably secured to the housing via pivot of the pivot portions.
