Abstract: A scanner obtains point-cloud data of adjoining parts of a product. A computing device reads two point-clouds from the point-cloud data, fits two or more lines according to the two point-clouds, selects two lines that have the same ascending direction from the two or more lines, and creates a two-dimensional coordinates system base on the two selected lines. The computing device determines a highest point in each of the two point-clouds based on distances from each point in either of the point-clouds to a corresponding selected line, and determines two nearest points in the two point-clouds. A difference between Y coordinates of the two highest points is determined as a gap-height of two adjoining parts of the product, and a difference between X coordinates of the two nearest points is determined as a gap-width between two adjoining parts.

Abstract: A remote computer monitors virtual machines in cloud servers of a data center. The remote computer obtains parameters of each virtual machine authorized to a user by a monitoring program when a user logs in a login interface in a client computer. The remote computer calculates a resource coefficient of each virtual machine according to the parameters of the virtual machine authorized to the user. The remote computer displays an icon corresponding to each virtual machine in the login interface according to the resource coefficient of each virtual machine.

Abstract: A method for managing a number of power supply units (PSUs) of a power supply device is provided. A total operation time of each PSU is counted. A number of the PSUs to be assigned to work is determined according to a load value of a load connected to the power supply device. Which of the PSUs will be assigned to work and which of the PSUs will be assigned to idle are determined according to the total operation time of each PSU and the determined number of the PSUs to be assigned to work. The PSUs to be assigned to work are controlled to enter a work state, and the PSUs to be assigned to idle are controlled to enter a standby mode.

Abstract: In a method for managing serial attached small computer system interface (SAS) expanders using a host computer, the host computer connects to an SAS expander storage system through a redundant array of independent disks (RAID) card. The SAS expander storage system includes a first switch device, a first SAS expander, a second SAS expander, a second switch, a flash memory, and hard disk drives. The method controls the first switch device to switch the RAID card from the first SAS expander to the second SAS expander when the first SAS expander fails to function, controls the second switch device to switch the flash memory from the first SAS expander to the second SAS expander, and controls the first switch device to connect each of the hard disk drives to the second SAS expander.

Abstract: Method of measuring a point cloud of an object includes obtaining the point cloud of the object from a storage device of the electronic device. Based on the point cloud, a triangular mesh surface is constructed and triangles of the triangular mesh surface are determined. According to the triangles, a reference plane is determined. According to the reference plane, a three dimensional (3D) object coordinate system is established. 3D object coordinates of points in the point cloud are calculated in the 3D object coordinate system. Measurement elements of a profile of the point cloud are determined and points in the point cloud corresponding to each of the measurement elements are determined. According to the 3D object coordinates of the determined points corresponding to each of the measurement elements, each of the measurement elements are fit. A distance and an angle of two fit measurement elements are calculated.

Abstract: In a database accessing method using an electronic device having a database, character fields and corresponding attributes are predefined. An entity object including the character fields is generated and provided to a client device for inputting business data. After receiving an encapsulated entity object from the client device, the business data including selected character fields, corresponding character data, and an operation request for the database are acquired. When the database includes a data table and the data table includes the character fields corresponding to the selected character fields, the selected character fields and the character data of the selected character fields are verified. When the selected character fields and the character data of the selected character fields are valid, character data of the character fields corresponding to the selected character fields are updated using the character data of the selected character fields according to the operation request.

Abstract: In a method for monitoring safe driving of a vehicle, the method obtains a current image captured by an image capturing device positioned on an outside sideview mirror of the vehicle, determines a horizontal distance and a vertical distance between each pixel point in the current image and the lens of image capturing device, and selects a reference point from first specified pixel points whose horizontal distances are less than a first preset value. The method further determines second specified pixel points whose vertical distances are less than or equal to a second preset value based on the reference point, to obtains a processed image based on the second specified pixel points, and displays the processed image on an inside rearview mirror of the vehicle.
