Patent number: 6285980Abstract: A natural number recognition method and system that uses minimum classification error trained inter-word context dependent models of the head-body-tail type over a specific vocabulary. One part of the method and system allows recognition of spoken monetary amounts in financial transactions. A second part of the method and system allows recognition of numbers such as credit card or U.S. telephone numbers. A third part of the method and system allows recognition of natural language expressions of time, such as time of day, day of the week and date of the month for applications such as scheduling or schedule inquires. Even though limited natural language expressions are allowed, context sharing between similar sounds in the vocabulary within a head-body-tail model keeps storage and processing time requirements to manageable levels.Type: GrantFiled: November 2, 1998Date of Patent: September 4, 2001Assignee: Lucent Technologies Inc.Inventors: Malan Bhatki Gandhi, John Jacob

Patent number: 6282275Abstract: A method for storing caller identification information as a log of answered and unanswered telephone calls at a central server. This call log server is accessible by the internet, so if a subscriber is traveling, he or she is still able to access and read a list of answered and unanswered calls to the subscriber's home station. Internet devices such as browsers that are internet telephony capable may return a call from the call log list using a point and click sequence. The call log may be processed from natural chronological order into a personal priority order such as: family, professional and everything else. This call log may also be forwarded via e-mail to the subscriber. Such e-mail forwarding may be either contemporaneously with call logging or periodically.Type: GrantFiled: August 7, 1998Date of Patent: August 28, 2001Assignee: Lucent Technologies Inc.Inventors: Vijay Kumar Gurbani, Ajay Jain

Patent number: 5689706Abstract: Techniques for providing replicated files in a distributed system. A replicated file has a set of copies in components of the distributed system. Operations on the copies have the same semantics for the application processes accessing them as operations on a single copy of a file in a system where all processes execute on the same host. These semantics are achieved by means of a distributed synchronization system. Each replicated file has a read token and a write token. In order for an application process to perform an operation on a replicated file, the token required for the operation must be in the process's host and the process must have access to the token. Tokens are passed between hosts by token servers which respond to requests for tokens from application processes and from other token servers. The techniques are implemented using a library which replaces a standard I/O library, and may thus be employed without modification to hardware or the operating system.Type: GrantFiled: October 10, 1996Date of Patent: November 18, 1997Assignee: Lucent Technologies Inc.Inventors: Chung-Hwa Herman Rao, Andrea H. Skarra

Patent number: 4969385Abstract: A method for operating a digital synthesizer type of electronic musical instrument to rapidly make available digital oscillators to produce newly keyed notes even when all digital oscillators are currently active with previous assignments. The method contains a way of maintaining a record of the digital oscillator with the lowest amplitude, and reassigning this lowest amplitude digital oscillator to produce the new note on the rationale that the output of the lowest digital oscillator will be the least missed if an output has to be prematurely curtailed. Beside just a straight amplitude critereon, the method also allows for prioritizing some low amplitude outputs over others to make a more pleasing performance. The invention also includes an apparatus for performing the method.Type: GrantFiled: December 28, 1989Date of Patent: November 13, 1990Assignee: Gulbransen, Inc.Inventors: Anthony G. Williams, David T. Starkey

Patent number: 4941387Abstract: A digital synthesizer type electronic musical instrument that has the ability to automatically accompany a pre-recorded song with appropriate chords. The pre-recorded song is transposed into the key of C major, divided into a number of musical sequences, and then stored in a data structure. By analyzing the data structure of each musical sequence, the electronic musical instrument also can provide intelligent accompaniment, such as voice leading, to the notes that the operator plays on the keyboard.Type: GrantFiled: January 19, 1988Date of Patent: July 17, 1990Assignee: Gulbransen, IncorporatedInventors: Anthony G. Williams, David T. Starkey

Patent number: 4642475Abstract: The invention pertains to an uninterruptible power supply (UPS) with a rectifier supplied with power by a power network, connected to an intermediate circuit having a battery as well as to an inverter connected to the intermediate circuit for supplying an interruption protected power source. The control for the main input rectifier and the inverter is supplied using two secondary rectifiers, whose outpus are connected in parallel through decoupling diodes. The first secondary rectifier which supplies power to the control unit in normal operation, is connected to the input power network.Type: GrantFiled: May 20, 1985Date of Patent: February 10, 1987Assignee: Siemens AktiengesellschaftInventors: Dietmar Fischer, Christian Kublick

Patent number: 4613734Abstract: The invention concerns a mounting arrangement for an arc-quenching chute cover upon a base of a switching device. For that purpose it includes resilient clamping elements, such as a quick-release fastener which guides a coil spring and a rubber bushing. The anchoring of the quick-release fastener in the base is achieved by twisting a pin into a widened region. When excess pressures arise inside the arc-quenching chute cover, the rubber bushing is compressed and has a damping effect on the shaft portion of the quick-release fastener passing through it.Type: GrantFiled: March 11, 1985Date of Patent: September 23, 1986Assignee: Siemens AktiengesellschaftInventors: Guenther Eckert, Franz Singer

Patent number: 4589162Abstract: A carrying device is provided for electrical apparatus enclosure. The carrying device has a handle which is attached to carrying arms which are bent in an approximate semi-circle. The arms are movably mounted behind the wall of enclosure for movement of the handle from a rest position to a working position. In the rest position the handle is flush in an opening of the enclosure and in working position, the handle is swung out upwards of the opening of the enclosure.Type: GrantFiled: September 19, 1984Date of Patent: May 20, 1986Assignee: Siemens AktiengesellschaftInventors: Hermann Manz, Walter Schweiger
