Publication number: 20120013404Abstract: A CMOS differential power amplifier having broadband input matching with Noise and Non-linearity Cancellation. The broadband input match is realized by using two “Diode-Connected” NFETs (i.e., N-type Field Effect Transistors). Resulting noise degradation is reduced by using a noise cancellation structure. By using the same structure the disclosed method and apparatus also achieves non-linearity cancellation.Type: ApplicationFiled: June 28, 2011Publication date: January 19, 2012Applicant: ENTROPIC COMMUNICATIONS, INC.Inventor: Wai Lim NGAI

Patent number: 8098605Abstract: Growth of a distributed communication system is facilitated through dynamic addition of routing elements. A new routing element may be added to a network of routing elements by first establishing a connection between the new routing element and an existing routing element in the network. The connection may be either wireless or wireline. At least one address is assigned to the new routing element. Each assigned address comes from a pool of addresses maintained at the existing routing element. At least one pool of addresses is issued to the new routing element, permitting the new routing element to dynamically add yet another new routing element to the network of routing elements.Type: GrantFiled: August 27, 2008Date of Patent: January 17, 2012Assignee: Qwest Communications International Inc.Inventors: Angus O.

Patent number: 8098806Abstract: A wireless communication system has a central computer, one or more access points and personal badges that communicate with the one or more access points. The central computer includes a database indexed by either user identification codes or badge serial numbers. When a user activates a badge, the central computer assigns the badge to the user who activated the badge so that any message for the user is directed to the badge. The user may also access his personal data section in a central computer database through the badge while the activation is valid. When the user deactivates the badge, the central computer deletes the association and returns the badge to a non-user-specific state. Where docking stations are available to rest the badges not being used, the badges may be configured so that they are activated when decoupled from the docking stations and deactivated when coupled to the docking stations.Type: GrantFiled: August 28, 2003Date of Patent: January 17, 2012Assignee: Vocera Communications, Inc.Inventor: Robert E. Shostak

Patent number: 8099281Abstract: A device and related methods for word-sense disambiguation during a text-to-speech conversion are provided. The device, for use with a computer-based system capable of converting text data to synthesized speech, includes an identification module for identifying a homograph contained in the text data. The device also includes an assignment module for assigning a pronunciation to the homograph using a statistical test constructed from a recursive partitioning of training samples, each training sample being a word string containing the homograph. The recursive partitioning is based on determining for each training sample an order and a distance of each word indicator relative to the homograph in the training sample. An absence of one of the word indicators in a training sample is treated as equivalent to the absent word indicator being more than a predefined distance from the homograph.Type: GrantFiled: June 6, 2005Date of Patent: January 17, 2012Assignee: Nunance Communications, Inc.Inventor: Philip Gleason
