Provided is a bipolar electrode probe, which includes a conductive needle, an insulation layer, a conductive sleeve, and an insulation sleeve. The conductive needle has a longitudinal direction and a transverse direction perpendicular to the longitudinal direction. The insulation layer covers the conductive needle and has a first opening. The conductive sleeve covers the insulation layer and has a second opening. The insulation sleeve covers the conductive sleeve. When the bipolar electrode probe is turned on, a longitudinal electric field is formed from a front end of the conductive needle to the conductive sleeve along the longitudinal direction. A transverse electric field is formed from the conductive needle to the conductive sleeve via the first opening and the second opening along the transverse direction.

A radiofrequency ablation electrode needle includes at least one first segment and at least two second segments. The at least one first segment and the at least two second segments are exposed on a surface of the needle body. An impedance of the at least one first segment is smaller than an impedance of the at least two second segments and at least one of the at least one first segment is disposed between two immediately adjacent ones of the at least two second segments. Besides, the radiofrequency ablation electrode needle is a monopolar electrode needle.

A method of image reconstruction is provided. When an object is not placed in a measurement space, first intensity images of an electromagnetic wave passing through the measurement space and corresponding to photon energy levels are measured. When the object is placed in the measurement space, second intensity images of the electromagnetic wave passing through the object and corresponding to photon energy levels are measured. In a database, data including an attenuation coefficient of each substance respectively having components irradiated by the electromagnetic wave corresponding to each photon energy level and a thickness of each substance in a transmission direction of the electromagnetic wave corresponding to each photon energy level are provided. Attenuation images of the object respectively corresponding to the components are calculated according to the data and the first and second intensity images. An image reconstruction system and a method and system of image construction are also provided.

The present invention provides a medium for storing a subtitle data structure of an audio/video program and a method for displaying the same. The subtitle data structure of the audio/video program includes a plurality of character packages and a background image package, wherein each character package further has a header that includes the start and the end of a presenting time stamp (PTS), X-Y coordinates of the character, X length, Y length and a color (or colors) of the character, as well as pixel data for displaying the character. Compared with prior art, using the subtitle data structure of the present invention can considerably save the required medium capacity for storing the subtitle data.

A watermark coding method and its recording medium utilize image interleaving and wavelet-based transformation to enhance the robustness of the image. The watermark series to be inserted is converted, encrypted, and modulated to increase the difficulty in decoding and restoring. Finally, the watermark is distributed and hidden in various frequency bands of the image in a frequency hopping way, generating a robust watermarked image. When used in a recording medium, side information produced during coding is recorded in the lead-in area of the recording medium to reduce the chances of illegal copying.

Watermark coding method and recording medium thereof

A method for repairing video/audio files of multimedia video/audio disks is provided. The disclosed method may repair the fields with errors in the video/audio files after recording by utilizing the rewritable characteristic of rewritable optical disks. The errors caused by the video/audio instantaneous editing and recording platform may be reduced according to the disclosed method such that the repaired films may play fast forward/backward smoothly, perform Time Search function accurately, and display presentation time correctly, and are compatible to players of different specifications.
