A method is proposed for improving the layout efficiency in laying out electronic components, which is applicable to information processing equipment, to accelerate the layout of electronic components. First, a first two-dimensional plan view including various electronic component members is preset using a drafting software platform. Subsequently, the two-dimensional plan view is converted to a text file and all the relevant data of the electronic components contained in the two-dimensional plan view are encoded in the text file. Then, all of the electronic component members contained in the first two-dimensional plan view are displayed in a second two-dimensional plan view, and a function selection menu is generated by an arithmetic process. Therewith, a user is able to select the data of the electronic component contained in the text file via the function selection menu to perform the layout operations for a printed circuit board.

A method for detecting defects when mixed colors among color channels on a liquid crystal monitor is disclosed. The disclosed method utilizes the interference of four channels of red, green, blue and white colors to check whether a detected liquid crystal monitor can normally show the mixed colors. A rectangular channel drawing is shown on a liquid crystal monitor; wherein the most upper left point, the most upper right point, the most lower left point, and the most lower right point are respectively allocated by red, green, blue, and white pixels. Each color channel then extends separately along the diagonal direction and accompanied with color intensity gradually decreasing to obtain an interference diagram that contains several arc stripes on the rectangular drawing. Accordingly, those defective pixels will be clearly indicated in the rectangular channel drawing because they are usually flashing visually. Additionally, color sensors can be employed to further analyze the channel weights of each pixel of the detected liquid crystal monitor, and the detecting information can be further illustrated by using a menu or a display window according to the display mode of a liquid crystal monitor currently used.

A PC interval timer test method used in a personal computer to test the abnormality of the interval timer of a PC (personal computer) by: calculating the difference between the periodic interrupt frequency of the PC's CMOS Real Time Clock (R.T.C.) and the interval timer interrupt frequency within the same time period, and then judging the result by comparing the value of the difference thus obtained with the set maximum allowable value of error of the CMOS R.T.C.'s periodic interrupt frequency. The maximum frequency of the CMOS R.T.C. can be as high as 8192 Hz, so that the test error can be as minor as below 1/8192.

A method used to test the correctness of image data transited between the system memory and display memory is described as follows. First, a image data A is stored in a location B of the system memory. Then, the data of image A and a location C of display memory are stored into a Bitblt temporary storage means. The Bitblt engine is used to transit the data of image A stored in the location B of system memory to the location C of display memory. Then, the data of location C, location D of display memory, and image A are input into the Bitblt temporary storage means. The Bitblt engine is used to transit the data of image A from the location C to the location D of display memory. The data of image A and location E are input into the Bitblt temporary storage means. The Bitblt engine is used to transit the data of image A from the location D into the location E of the system memory. Then, the image data A in location B of system memory is compared with the image data A in location E of system memory for determining whether the image data A is correct after the transiting procedure completed.

The present invention herein relates to a kind of testing method of the integrity of the software pre-installed in a computer hard disk by providing a file information access function to directly read data on the physical magnetic tracks of a hard disk through a lower level operating method, and to obtain and then test the file names, file sizes, file storage locations and other information stored in all partitions (including hidden partitions and normal partitions). The present invention also permits the operator to manually input the names of known files and directories that may be altered during the computer start-up routine in advance to enable the effects of said known files and directories being disregarded during the testing procedures, and, furthermore, to create a standard pre-installed software information file that is compared with a temporary file created from the software information on the hard disk, thereby ensuring that the software pre-installed on a hard disk of computer sold by a manufacturer is reliable and accurate to meet consumers' expectations.

A method for testing noise of a record/play-back loop in an audio system of a personal computer (PC) system is disclosed. The audio system comprises an analog-to-digital (A/D) converter, an FM synthesizer, an FM register, a mixer, an output device, an input device, and a connection element connected between the output device and the input device. The PC system has a system bus for communicating with the A/D converter and the FM synthesizer. The method comprises the steps of: (a) the PC system is started to issue a command to the FM synthesizer to output a sinusoidal analog signal to the output device via the mixer; (b) the analog signal is outputted to the input device via the connection element and then is outputted to the A/D converter for being converted to a digital signal which further stored as a digitized audio document; (c) the PC system performs a mathematical analysis on the audio document in order to calculate a signal-to-noise (S/N) ratio and a signal distortion of the record/play-back loop; and (d) the S/N ratio and the signal distortion described in step (c) are compared with a pair of predetermined standards respectively in order to determine that whether the S/N ratio and the signal distortion meet the predetermined standards.
