Abstract: A method and a system for mental index prediction are provided. The method includes the following steps. A plurality of images of a subject person are obtained. A plurality of emotion tags of the subject person in the images are analyzed. A plurality of integrated emotion tags in a plurality of predetermined time periods are calculated according to the emotion tags respectively corresponding to the images. A plurality of preferred features are determined according to the integrated emotion tags. A mental index prediction model is established according to the preferred features to predict a mental index according to the emotional index prediction model.

Abstract: A method of manufacturing chip antenna and a structure of the chip antenna. The method includes the following steps: preparing a substrate, drilling a plurality of rows of external through holes and internal through holes arranged longitudinally, forming fishing grooves at the predetermined distance between every two of the internal through holes arranged longitudinally, electroplating a metal material on the external through holes and the internal through holes, to form a conductive layer. Afterward, a circuit layer is formed on the conductive layer by exposure, development, and etching techniques. An ink is printed on the substrate after the circuit layer finished, and the ink cover parts of the circuit layer and parts of the substrate exposed, to form a solder mask and a recognition pattern layer. Finally, a longitudinal cutting line and a horizontal cutting line are cut on the substrate, and to form a chip antenna.

Abstract: The present invention relates to a resonator and a filter using the same, and particularly, to a resonator, which includes partition walls that alternate vertically or horizontally in a cavity, and a filter using the resonator. The resonator includes: a housing which is made of a conductive material and includes a cavity; a cover which is made of a conductive material and fixed to an upper portion of the cavity, and seals the cavity; one or more first partition walls which are connected to one surface of inner surfaces of the cavity; and one or more second partition walls which are connected to the opposite surface to the one surface, in which the first partition walls and the second partition walls are made of a conductive material and have shapes corresponding to each other, and the first partition walls and the second partition walls alternate with each other.
