摘要： A computing device and a method for controlling access to driver programs obtains a first system time at the time that an application uses a CTL_CODE to access a driver program. The first system time and the CTL_CODE is encrypted to generate an encrypted CTL_CODE which is then sent to the driver program. The encrypted CTL_CODE is decrypted to obtain the first system time and the CTL_CODE therein. A second system time at the time that the driver program receives the encrypted CTL_CODE is obtained and compared with the first system time. Access to the driver program is allowed if a difference between the first system time and the second system time falls within a predetermined range, and access to the driver program is forbidden if the difference is beyond the predetermined range.

摘要： A method for transferring one or more guest operating system (OS) using a remote server. The remote server periodically obtains a central processing unit (CPU) utilization ratio of each guest OS installed in each cloud server of the data center. The remote server counts the number of times of obtaining the CPU utilization ratio, and calculates a predicted average of the CPU utilization ratio for each cloud server if the counted number of the times is equal to a predetermined number. The remote server transfers one or more guest OS from the cloud server to other cloud servers before a predetermined time, in response to a determination that the predicted average of the CPU utilization ratio of the cloud server is greater than a predetermined average.

摘要： A method corrects trapezoid distortion of projected images using a projector. The projector includes a projection lens, a driver device, an image capturing device, and a storage system. A rectangular picture is read from the storage system and projected on a projection area by the projection lens. The method controls the image capturing device to capture an image from the projection area when the projection lens increases one trapezoid row correction grade, and corrects each trapezoid row of the captured image if the captured image has trapezoid rows. The method further controls the image capturing device to capture an image from the projection area when the projection lens increases one trapezoid column correction grade, and corrects each trapezoid column of the captured image if the captured image has trapezoid columns.

The method sets an interval step according to a focusing range of the projection lens, reads a predefined picture from a storage system of the projector, and controls the projection lens to project the picture to a projection area. The method controls the image capturing device to capture an image of the picture from the projection area when the projection lens moves at every interval step, and analyzes a contrast of each of the images to determine an optimal image from the images. The method determines a current focus of the projection lens having the optimal image as an optimal focus of the projection lens, and drives the driver device to control the projection lens to move at the optimal focus.

摘要： In a method for validating speed of a fan of an electronic device, different speeds of the fan are set for validation. The method controls the fan to operate under each of the set speeds in turn, and controls a camera device to continuously capture images of the fan with a shutter speed of the camera device corresponding to the set speed. The images are transmitted to a comparison unit to be analyzed for sameness and clarity. The fan is determined to work abnormally if not all the images are sameness or if at least one image is unclear, and the fan is determined to work normally if all the images are sameness or clear. A validation report is generated to indicate whether the fan is normal or abnormal according to the determination.

摘要： A method captures images of objects using an image capturing apparatus. The method obtains x-coordinate values, y-coordinate values, and z-coordinate values of the accelerations of a camera device sensed by a gravity sensor in a default time interval, calculates three-dimensional coordinate differences according to the obtained x-coordinate, y-coordinate, and z-coordinate values, and determines whether the three-dimensional coordinate differences are less than corresponding predefined thresholds. If at least one coordinate difference is not less than a corresponding predefined threshold, the method delays a period of time to obtain the x-coordinate, y-coordinate, and the z-coordinate values in a next default time interval. If all the three-dimensional coordinate differences are less than the corresponding predefined thresholds, the method controls the camera device to capture images of the subject object.
