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: System and methods directed to identifying music theory labels for audio tracks are described. More specifically, a first training set of audio portions may be generated from a plurality of audio tracks, segments within the plurality of audio tracks being labeled according to a plurality of music theory labels. A deep neural network model may then be trained using the first training set as an input, a first loss function for music theory label identifications of audio portions of the first training set, and a second loss function for segment boundary identifications within the audio portions of the first training set. In examples, the music theory label identifications and the segment boundary identifications are generated by the deep neural network model. A first audio track is received and segment boundary identifications and music theory labels for segments within the first audio track are generated using the deep neural network model.

Abstract: The present invention provides an in-vehicle terminal and a method for turning on/off the in-vehicle terminal. The in-vehicle terminal includes a switch circuit. The switch circuit includes: an output circuit, a control circuit, a first input circuit, a second input circuit and a control circuit. The first input circuit is configured to transmit the received first trigger signal to the output circuit. The second input circuit is configured to transmit the received second trigger signal to the output circuit. The output circuit is configured to output a first control signal for turning on/off the vehicle terminal according to the first trigger signal or the second trigger signal. The control circuit is configured to block the second trigger signal from being transmitted to the output circuit when both the first input circuit and the second input circuit are transmitting a corresponding trigger signal to the output circuit.

Abstract: A reservation system for watching online video is used in wireless communication equipment to watch online video via network. The reservation system contains: at least one network server linking to an instant video platform for storing live video medias and for facilitating a user to view and click a desired live video media; a user login interface linking to the plurality of live video medias so as to login and to confirm a user identity; a playing session schedule served to reserve a playing time and a playing session; an online traffic seating chart linking with the playing session schedule so as to confirm viewer's number of the playing time and the playing session, such that the user confirms booking; and a playback information transmission unit linking with the online traffic seating chart and generating playing information based on a booking confirmation and transmitting the playing information to the user.

Abstract: Light condensing lens, module, and photoelectric transducing apparatus are disclosed. The lens has a light receiving surface, a bottom surface, and two side surfaces. The side surfaces are obliquely connected with the light receiving surface and the bottom surface. By designing the radian of the light receiving surface, the light streams can be condensed to a predetermined region no matter where the light source is. Additionally, an auxiliary light module is provided for reflecting the light streams to the predetermined region, in order to increase the photoelectric transducing efficiency.

Abstract: A wireless transmission adaptation method and apparatus for converting a wireless signal between a first and second electrical devices are described. The apparatus has a first wireless transmission interface, a second wireless transmission interface and a control unit. The first wireless transmission interface is used for compatibility with a first wireless signal from the first electrical device. The second wireless transmission interface is used for compatibility with a second wireless signal from the second electrical device. The control unit is electrically coupled between the first and second wireless transmission interfaces. The control unit provides the format conversion for the signals transmitted between the first and second wireless transmission interfaces.

Abstract: A curved surface signal pick-up device comprises a rotary disk and graphite brushes. The rotary disk has grid ring on the side thereof. The grid ring have a common portion and transferring portions spaced with equal or unequal distances, each of the transferring portions are arranged alternatively so that the common portion and transferring portions on the rotary disk are arranged on the same radius. Graphite brushes made by dividing an single located element, one end of the graphite brushes are connected on a circuit board for transferring the receiving different signals, while another end of the graphite brushes are contacted with the common portion and the transferring portions of the grid ring.
