A system and method for the prevention of malicious file copying detects a file copy operation indicative of copying a file to an electronic clipboard. If the file copy operation is detected, the computer reads file contents of the copied file, and scrambles the file contents. If a file paste operation indicative of the copied file being pasted to a designated file system path, the computer pastes the scrambled file to the designated file system path. File attributes of the scrambled file are the same as file attributes of the copied file.

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.

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.

A computer-implemented method for testing an operating condition of light emitting diodes (LEDs) on a motherboard includes assigning an LED identification for each LED according to positions of the LEDs on the motherboard, selecting a first LED identification for a first LED and a second LED identification for a second LED, setting the first LED in a bright state, the second LED in a dim state, and any remaining LEDs in a flicker state, and controlling the LEDs to operate. The method further includes determining whether the total count of the LEDs in the bright state is equal to one, and whether the total count of the LEDs in the dim state is equal to one, comparing the first LED identification input with the first LED identification, and comparing the second LED identification input with the LED identification, and reporting a comparison result.
