Abstract: A method of through tubing cement evaluation includes obtaining acoustic cement bond evaluation data relating to a property of a cement bond of a cased-borehole for each of a plurality of acoustic methods, wherein the acoustic cement bond evaluation data comprises a quality control (QC) value indicative of a confidence level of cement bonding condition, determining an eccentricity value of a tubing relative to a casing in the borehole, determining an output of each acoustic method by combining the eccentricity value and the acoustic cement evaluation data associated with each acoustic method, combining the output of each acoustic method to generate an optimized cement bonding index log of the cement bond, and employing the optimized cement bonding index log to provide an interpretation of an overall cement bonding condition.

Abstract: An authentication method of a specified condition for executing authentication of the specified condition for a user through a device is provided. The authentication method includes the following steps: actuating a first capturing unit of the device to capture an information to be authenticated of the user; actuating the first capturing unit or a second capturing unit of the device to capture a specified condition information; and executing an analysis judgment software to analyze and judge whether the information to be authenticated is consistent with the specified condition information or not, if consistent, the user being authenticated to reach the specified condition, thereby overcoming the problem of the prior art that needs troublesome manual steps for authentication.

Abstract: A verification method includes displaying a selected pattern set on a display device electrically connected with a user apparatus. One of a first selected pattern and a second selected pattern as an as-selected pattern is selected. The as-selected pattern is used as a first target pattern, and the other is used as a second target pattern. A match object area and a target object area on the display device are displayed. The selected pattern is displayed in the match object area, and the first and second object patterns are displayed in the target object area. A user operates the user apparatus or a connected wearable device to control and select the as-selected pattern in the match object area on the display device or on another display device. When the as-selected pattern conforms to the first object pattern, the verification is finished.

Abstract: A server, a user apparatus and a terminal device are provided. The server includes a transmission interface, a database and a processor. The transmission interface receives an identification verification request from the user apparatus. The processor captures a plurality of selected patterns from a plurality of database patterns stored in the database according to the identification verification request, selects at least one target pattern from the plurality of selected patterns, and enables the user apparatus to display the plurality of selected patterns and the at least one target pattern in a match object area and a target object area of a user interface displayed by the user apparatus, respectively. An identification verification procedure is finished while the processor determines that one of the plurality of selected patterns that corresponds to the at least one target pattern is selected to conform to the at least one target pattern.
