摘要:
A prepaid accounting system for a wireless local area network (WLAN) and a method thereof are provided. The system includes: an authentication control point, an authentication server, and a service control point. The authentication control point is used to control access of a subscriber to WLAN; the authentication server is used to perform authentication, authorization and accounting for the subscriber; and the service control point is used to store and update subscriber information. The method includes the steps of: upon the start of accounting, an authentication server requesting a service control point to check account balance of a subscriber; during the accounting, the authentication server periodically requesting the service control point to check the account balance of the subscriber; and upon the termination of accounting, the authentication server notifying the service control point of the termination of accounting and the service control point updating the balance.

This invention provides an isolated strain of Hepatitis B virus designated Human Hepatitis B Virus Surface Antigen-‘S’-133 Oon Strain (Methionine to Threonine) which constituent viral genome is deposited under Accession Nos. P97121501, P97121502 and P97121503 with the European Collection of Cell Culture on 15th Dec. 1997. This invention also provides an isolated nucleic acid encoding a polypeptide which is a mutant major surface antigen of a strain of hepatitis B virus, such polypeptide having an amino acid sequence which differs from the amino acid sequence of a major surface antigen of a wild type hepatitis B virus in that the amino acid at position number 133 of such polypeptide is a threonine rather than a methionine. This invention also provides an isolated nucleic acid which encodes a peptide, wherein the peptide is encoded by a nucleic acid molecule comprising nucleotides 527 through 595 of SEQ. I.D. No. 1 and the purified peptide. This invention also provides various methods of using the disclosed isolated nucleic acid and peptides.

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 input signal is transformed into the frequency domain and then subdivided into bands corresponding to different frequency ranges. Adaptive thresholds are applied to the data from each frequency band separately. Thus the short-term band-limited energies are tested for the presence or absence of a speech signal. The adaptive threshold values are independently updated for each of the signal paths, using a histogram data structure to accumulate long-term data representing the mean and variance of energy within the respective frequency band. Endpoint detection is performed by a state machine that transitions from the speech absent state to the speech present state, and vice versa, depending on the results of the threshold comparisons. A partial speech detection system handles cases in which the input signal is truncated.
