    摘要: An H bridge circuit includes a gate driver circuit coupled to a gate of an NMOS device. The output of the gate driver circuit is at a voltage from 0.1V to 0.4V during a dead time of the H bridge circuit. The gate voltage of the NMOS device is biased at 0.1˜0.4V to overcome the problems of minority carrier injection and power dissipation as compared with VG=0 in a conventional H bridge circuit.

    摘要: The system retrieves information from the internet using multiple search engines that are simultaneously launched by the search engine commander. The commander is responsive to a speech-enabled system including a speech recognizer and natural language parser. The user speaks to the system in natural language requests, and the parser extracts the semantic content from the user's speech, based on a set of goal oriented grammars. The preferred system includes a fixed grammar and an updatable or downloaded grammar, allowing the system to be used without extensive training and yet capable of being customized for a particular user's purposes. Results obtained from the search engines are filtered based on information extracted from an electronic program guide and from prestored user profile data. The results may be displayed on screen or through synthesized speech.

    摘要: The remote control unit supports multi-modal dialog with the user, through which the user can easily select programs for viewing or recording. The remote control houses a microphone into which the user can input natural language speech. The input speech is recognized and interpreted by a natural language parser that extracts the semantic content of the user's speech. The parser works in conjunction with an electronic program guide, through which the remote control system is able to ascertain what programs are available for viewing or recording and supply appropriate prompts to the user. In one embodiment, the remote control includes a touch screen display upon which the user may view prompts or make selections by pen input or tapping. Selections made on the touch screen automatically limit the context of the ongoing dialog between user and remote control, allowing the user to interact naturally with the unit. The remote control unit can control virtually any audio-video component, including those designed before the current technology. The remote control system can be packaged entirely within the remote control handheld unit, or components may be distributed in other systems attached to the user's multimedia equipment.

    摘要: Speech recognition and natural language parsing components are used to extract the meaning of the user's spoken input. The system stores a semantic representation of an electronic program guide, and the contents of the program guide can be mapped into the grammars used by the natural language parser. Thus, when the user wishes to navigate through the complex menu structure of the electronic program guide, he or she only needs to speak in natural language sentences. The system automatically filters the contents of the program guide and supplies the user with on-screen display or synthesized speech responses to the user's request.

    摘要: Speech input supplied by the user is evaluated by the speaker verification/identification module, and based on the evaluation, parameters are retrieved from a user profile database. These parameters adapt the speech models of the speech recognizer and also supply the natural language parser with customized dialog grammars. The user's speech is then interpreted by the speech recognizer and natural language parser to determine the meaning of the user's spoken input in order to control the television tuner. The parser works in conjunction with a command module that mediates the dialog with the user, providing on-screen prompts or synthesized speech queries to elicit further input from the user when needed. The system integrates with an electronic program guide, so that the natural language parser is made aware of what programs are available when conducting the synthetic dialog with the user.
