Abstract: A method for detecting abnormal direct current voltage measurement in a modular multilevel converter high voltage direct current transmission system is provided. In the method, a valve group voltage at a detection pole is obtained, voltages at voltage measurement points at the detection pole are collected, and comparison and determination are performed based on the actual arrangement of the voltage measurement points, and then whether an abnormal measurement occurs at each of the voltage measurement points is determined.

Abstract: The present invention provides methods and systems for managing a call based on multimedia data. According to one embodiment, the invention provides a method for managing a call. The method includes receiving first data related to a call sent by a calling party to a called party. In response to the first data, the method obtains from a database second data related to the call. At least one of the first data, the second data, and a combination of the first and second data includes multimedia data. The method manages the call based at least in part on the multimedia data. In another embodiment, the present invention provides a system for managing a call. The system includes: a database operative to store data associated with subscribers; and a MPCM service in communication with the database. The MPCM service has an interface for communicating over a network. The MPCM service receives over the network first data related to a call sent by a calling party to a called party.

Abstract: A real-time personal advisory service. In a preferred embodiment, experts access a server and register, providing their credentials, charge rates, and keywords related to their field of expertise. Information regarding the experts and customers are stored in a database. A registered customer sends a question as an SMS message to the server through a cellular device. The server scans the question for keywords and uses the keywords to query the database, generating a list of experts likely to be willing to answer the question. The question is then forwarded as another SMS message to the experts. Experts wanting to answer the question press an accept button, sending an SMS message back to the server. The server sends an SMS message to the customer, indicating that there are experts who want to answer the question. The customer selects an expert and replies to the message. The server then bridges the parties.
